Matter is anything that occupies space and has rest mass (or invariant mass). It is a general term for the substance of which all physical objects consist.^[1][2] Typically, matter includes atoms and other particles which have mass. Mass is said by some to be the amount of matter in an object and volume is the amount of space occupied by an object, but this definition confuses mass and matter, which are not the same.^[3] Different fields use the term in different and sometimes incompatible ways; there is no single agreed scientific meaning of the word "matter," even though the term "mass" is better-defined.

Contrary to the previous view that equates mass and matter, a major difficulty in defining matter consists in deciding what forms of energy (all of which have mass) are not matter. In general, massless particles such as photons and gluons are not considered forms of matter, even though when these particles are trapped in systems at rest, they contribute energy and mass to them. For example, almost 99% of the mass of ordinary atomic matter consists of mass associated with the energy contributed by the gluons and the kinetic energy of the quarks which make up nucleons. In this view, most of the mass of ordinary "matter" consists of mass which is not contributed by matter particles.

For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470–380 BC).^[4] Over time an increasingly fine structure for matter was discovered: objects are made from molecules, molecules consist of atoms, which in turn consist of interacting subatomic particles like protons and electrons.^[5][6]

Matter is commonly said to exist in four states (or phases): solid, liquid, gas and plasma. However, advances in experimental techniques have realized other phases, previously only theoretical constructs, such as Bose–Einstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quark–gluon plasma.^[7]

In physics and chemistry, matter exhibits both wave-like and particle-like properties, the so-called wave–particle duality.^[8][9][10]

In the realm of cosmology, extensions of the term matter are invoked to include dark matter and dark energy, concepts introduced to explain some odd phenomena of the observable universe, such as the galactic rotation curve. These exotic forms of "matter" do not refer to matter as "building blocks", but rather to currently poorly understood forms of mass and energy.^[11]

Historical development[link]

Origins[link]

The pre-Socratics were among the first recorded speculators about the underlying nature of the visible world. Thales (c. 624 BC–c. 546 BC) regarded water as the fundamental material of the world. Anaximander (c. 610 BC–c. 546 BC) posited that the basic material was wholly characterless or limitless: the Infinite (apeiron). Anaximenes (flourished 585 BC, d. 528 BC) posited that the basic stuff was pneuma or air. Heraclitus (c. 535–c. 475 BC) seems to say the basic element is fire, though perhaps he means that all is change. Empedocles (c. 490–430 BC) spoke of four elements of which everything was made: earth, water, air, and fire.^[12] Meanwhile, Parmenides argued that change does not exist, and Democritus argued that everything is composed of minuscule, inert bodies of all shapes called atoms, a philosophy called atomism. All of these notions had deep philosophical problems.^[13]

Aristotle (384 BC – 322 BC) was the first to put the conception on a sound philosophical basis, which he did in his natural philosophy, especially in Physics book I.^[14] He adopted as reasonable suppositions the four Empedoclean elements, but added a fifth, aether. Nevertheless these elements are not basic in Aristotle's mind. Rather they, like everything else in the visible world, are composed of the basic principles matter and form.

The word Aristotle uses for matter, ὑλη (hyle or hule), can be literally translated as wood or timber, that is, "raw material" for building.^[15] Indeed, Aristotle's conception of matter is intrinsically linked to something being made or composed. In other words, in contrast to the early modern conception of matter as simply occupying space, matter for Aristotle is definitionally linked to process or change: matter is what underlies a change of substance.

For example, a horse eats grass: the horse changes the grass into itself; the grass as such does not persist in the horse, but some aspect of it—its matter—does. The matter is not specifically described (e.g., as atoms), but consists of whatever persists in the change of substance from grass to horse. Matter in this understanding does not exist independently (i.e., as a substance), but exists interdependently (i.e., as a "principle") with form and only insofar as it underlies change. It can be helpful to conceive of the relationship of matter and form as very similar to that between parts and whole. For Aristotle, matter as such can only receive actuality from form; it has no activity or actuality in itself, similar to the way that parts as such only have their existence in a whole (otherwise they would be independent wholes).

Early modernity[link]

René Descartes (1596–1650) originated the modern conception of matter. He was primarily a geometer. Instead of, like Aristotle, deducing the existence of matter from the physical reality of change, Descartes arbitrarily postulated matter to be an abstract, mathematical substance that occupies space:

So, extension in length, breadth, and depth, constitutes the nature of bodily substance; and thought constitutes the nature of thinking substance. And everything else which can be attributed to body presupposes extension, and is only a mode of that which is extended

— René Descartes, Principles of Philosophy^[16]

For Descartes, matter has only the property of extension, so its only activity aside from locomotion is to exclude other bodies^[17]: this is the mechanical philosophy. Descartes makes an absolute distinction between mind, which he defines as unextended, thinking substance, and matter, which he defines as unthinking, extended substance.^[18] They are independent things. In contrast, Aristotle defines matter and the formal/forming principle as complementary principles which together compose one independent thing (substance). In short, Aristotle defines matter (roughly speaking) as what things are actually made of (with a potential independent existence), but Descartes elevates matter to an actual independent thing in itself.

The continuity and difference between Descartes' and Aristotle's conceptions is noteworthy. In both conceptions, matter is passive or inert. In the respective conceptions matter has different relationships to intelligence. For Aristotle, matter and intelligence (form) exist together in an interdependent relationship, whereas for Descartes, matter and intelligence (mind) are definitionally opposed, independent substances.^[19]

Descartes' justification for restricting the inherent qualities of matter to extension is its permanence, but his real criterion is not permanence (which equally applied to color and resistance), but his desire to use geometry to explain all material properties.^[20] Like Descartes, Hobbes, Boyle, and Locke argued that the inherent properties of bodies were limited to extension, and that so-called secondary qualities, like color, were only products of human perception.^[21]

Isaac Newton (1643–1727) inherited Descartes' mechanical conception of matter. In the third of his "Rules of Reasoning in Philosophy," Newton lists the universal qualities of matter as "extension, hardness, impenetrability, mobility, and inertia."^[22] Similarly in Optics he conjectures that God created matter as "solid, massy, hard, impenetrable, movable particles", which were "even so very hard as never to wear or break in pieces."^[23] The "primary" properties of matter were amenable to mathematical description, unlike "secondary" qualities such as color or taste. Like Descartes, Newton rejected the essential nature of secondary qualities.^[24]

Newton developed Descartes' notion of matter by restoring to matter intrinsic properties in addition to extension (at least on a limited basis), such as mass. Newton's use of gravitational force, which worked "at a distance," effectively repudiated Descartes' mechanics, in which interactions happened exclusively by contact.^[25]

Though Newton's gravity would seem to be a power of bodies, Newton himself did not admit it to be an essential property of matter. Carrying the logic forward more consistently, Joseph Priestley argued that corporeal properties transcend contact mechanics: chemical properties require the capacity for attraction.^[25] He argued matter has other inherent powers besides the so-called primary qualities of Descartes, et al.^[26]

Since Priestley's time, there has been a massive expansion in knowledge of the constituents of the material world (viz., molecules, atoms, subatomic particles), but there has been no further development in the definition of matter. Rather the question has been set aside. Noam Chomsky summarizes the situation that has prevailed since that time:

What is the concept of body that finally emerged?[...] The answer is that there is no clear and definite conception of body.[...] Rather, the material world is whatever we discover it to be, with whatever properties it must be assumed to have for the purposes of explanatory theory. Any intelligible theory that offers genuine explanations and that can be assimilated to the core notions of physics becomes part of the theory of the material world, part of our account of body. If we have such a theory in some domain, we seek to assimilate it to the core notions of physics, perhaps modifying these notions as we carry out this enterprise.

— Noam Chomsky, 'Language and problems of knowledge: the Managua lectures, p. 144^[25]

So matter is whatever physics studies and the object of study of physics is matter: there is no independent general definition of matter, apart from its fitting into the methodology of measurement and controlled experimentation. In sum, the boundaries between what constitutes matter and everything else remains as vague as the demarcation problem of delimiting science from everything else.^[27]

Late nineteenth and early twentieth centuries[link]

In the 19th century, following the development of the periodic table, and of atomic theory, atoms were seen as being the fundamental constituents of matter; atoms formed molecules and compounds.^[28]

The common definition in terms of occupying space and having mass is in contrast with most physical and chemical definitions of matter, which rely instead upon its structure and upon attributes not necessarily related to volume and mass. At the turn of the nineteenth century, the knowledge of matter began a rapid evolution.

Aspects of the Newtonian view still held sway. James Clerk Maxwell discussed matter in his work Matter and Motion.^[29] He carefully separates "matter" from space and time, and defines it in terms of the object referred to in Newton's first law of motion.

However, the Newtonian picture was not the whole story. In the 19th century, the term "matter" was actively discussed by a host of scientists and philosophers, and a brief outline can be found in Levere.^{[30][further explanation needed]} A textbook discussion from 1870 suggests matter is what is made up of atoms:^[31]

Three divisions of matter are recognized in science: masses, molecules and atoms.
A Mass of matter is any portion of matter appreciable by the senses.
A Molecule is the smallest particle of matter into which a body can be divided without losing its identity.
An Atom is a still smaller particle produced by division of a molecule.

Rather than simply having the attributes of mass and occupying space, matter was held to have chemical and electrical properties. The famous physicist J. J. Thomson wrote about the "constitution of matter" and was concerned with the possible connection between matter and electrical charge.^[32]

Later developments[link]

There is an entire literature concerning the "structure of matter", ranging from the "electrical structure" in the early 20th century,^[33] to the more recent "quark structure of matter", introduced today with the remark: Understanding the quark structure of matter has been one of the most important advances in contemporary physics.^{[34][further explanation needed]} In this connection, physicists speak of matter fields, and speak of particles as "quantum excitations of a mode of the matter field".^[8][9] And here is a quote from de Sabbata and Gasperini: "With the word "matter" we denote, in this context, the sources of the interactions, that is spinor fields (like quarks and leptons), which are believed to be the fundamental components of matter, or scalar fields, like the Higgs particles, which are used to introduced mass in a gauge theory (and which, however, could be composed of more fundamental fermion fields)."^{[35][further explanation needed]}

The modern conception of matter has been refined many times in history, in light of the improvement in knowledge of just what the basic building blocks are, and in how they interact.

In the late 19th century with the discovery of the electron, and in the early 20th century, with the discovery of the atomic nucleus, and the birth of particle physics, matter was seen as made up of electrons, protons and neutrons interacting to form atoms. Today, we know that even protons and neutrons are not indivisible, they can be divided into quarks, while electrons are part of a particle family called leptons. Both quarks and leptons are elementary particles, and are currently seen as being the fundamental constituents of matter.^[36]

These quarks and leptons interact through four fundamental forces: gravity, electromagnetism, weak interactions, and strong interactions. The Standard Model of particle physics is currently the best explanation for all of physics, but despite decades of efforts, gravity cannot yet be accounted for at the quantum-level; it is only described by classical physics (see quantum gravity and graviton).^[37] Interactions between quarks and leptons are the result of an exchange of force-carrying particles (such as photons) between quarks and leptons.^[38] The force-carrying particles are not themselves building blocks. As one consequence, mass and energy (which cannot be created or destroyed) cannot always be related to matter (which can be created out of non-matter particles such as photons, or even out of pure energy, such as kinetic energy). Force carriers are usually not considered matter: the carriers of the electric force (photons) possess energy (see Planck relation) and the carriers of the weak force (W and Z bosons) are massive, but neither are considered matter either.^[39] However, while these particles are not considered matter, they do contribute to the total mass of atoms, subatomic particles, and all systems which contain them.^[40][41]

Summary[link]

The term "matter" is used throughout physics in a bewildering variety of contexts: for example, one refers to "condensed matter physics",^[42] "elementary matter",^[43] "partonic" matter, "dark" matter, "anti"-matter, "strange" matter, and "nuclear" matter. In discussions of matter and antimatter, normal matter has been referred to by Alfvén as koinomatter.^[44] It is fair to say that in physics, there is no broad consensus as to a general definition of matter, and the term "matter" usually is used in conjunction with a specifying modifier.

Definitions[link]

Common definition[link]

The DNA molecule is an example of matter under the "atoms and molecules" definition.

The common definition of matter is anything that has both mass and volume (occupies space).^[45][46] For example, a car would be said to be made of matter, as it occupies space, and has mass.

The observation that matter occupies space goes back to antiquity. However, an explanation for why matter occupies space is recent, and is argued to be a result of the Pauli exclusion principle.^[47][48] Two particular examples where the exclusion principle clearly relates matter to the occupation of space are white dwarf stars and neutron stars, discussed further below.

Relativity[link]

In the context of relativity, mass is not an additive quantity.^[1] Thus, in relativity usually a more general view is taken that it is not mass, but the energy–momentum tensor that quantifies the amount of matter. Matter therefore is anything that contributes to the energy–momentum of a system, that is, anything that is not purely gravity.^[49][50] This view is commonly held in fields that deal with general relativity such as cosmology.

Atoms and molecules definition[link]

A definition of "matter" that is based upon its physical and chemical structure is: matter is made up of atoms and molecules.^[51] As an example, deoxyribonucleic acid molecules (DNA) are matter under this definition because they are made of atoms. This definition can be extended to include charged atoms and molecules, so as to include plasmas (gases of ions) and electrolytes (ionic solutions), which are not obviously included in the atoms and molecules definition. Alternatively, one can adopt the protons, neutrons and electrons definition.

Protons, neutrons and electrons definition[link]

A definition of "matter" more fine-scale than the atoms and molecules definition is: matter is made up of what atoms and molecules are made of, meaning anything made of positively charged protons, neutral neutrons, and negatively charged electrons.^[52] This definition goes beyond atoms and molecules, however, to include substances made from these building blocks that are not simply atoms or molecules, for example white dwarf matter — typically, carbon and oxygen nuclei in a sea of degenerate electrons. At a microscopic level, the constituent "particles" of matter such as protons, neutrons and electrons obey the laws of quantum mechanics and exhibit wave–particle duality. At an even deeper level, protons and neutrons are made up of quarks and the force fields (gluons) that bind them together (see Quarks and leptons definition below).

Quarks and leptons definition[link]

Under the "quarks and leptons" definition, the elementary and composite particles made of the quarks (in purple) and leptons (in green) would be "matter"; while the gauge bosons (in red) would not be "matter". However, interaction energy inherent to composite particles (for example, gluons involved in neutrons and protons) contribute to the mass of ordinary matter.

As may be seen from the above discussion, many early definitions of what can be called ordinary matter were based upon its structure or "building blocks". On the scale of elementary particles, a definition that follows this tradition can be stated as: ordinary matter is everything that is composed of elementary fermions, namely quarks and leptons.^[53][54] The connection between these formulations follows.

Leptons (the most famous being the electron), and quarks (of which baryons, such as protons and neutrons, are made) combine to form atoms, which in turn form molecules. Because atoms and molecules are said to be matter, it is natural to phrase the definition as: ordinary matter is anything that is made of the same things that atoms and molecules are made of. (However, notice that one also can make from these building blocks matter that is not atoms or molecules.) Then, because electrons are leptons, and protons and neutrons are made of quarks, this definition in turn leads to the definition of matter as being "quarks and leptons", which are the two types of elementary fermions. Carithers and Grannis state: Ordinary matter is composed entirely of first-generation particles, namely the [up] and [down] quarks, plus the electron and its neutrino.^[55] (Higher generations particles quickly decay into first-generation particles, and thus are not commonly encountered.^[56])

This definition of ordinary matter is more subtle than it first appears. All the particles that make up ordinary matter (leptons and quarks) are elementary fermions, while all the force carriers are elementary bosons.^[57] The W and Z bosons that mediate the weak force are not made of quarks or leptons, and so are not ordinary matter, even if they have mass.^[58] In other words, mass is not something that is exclusive to ordinary matter.

The quark–lepton definition of ordinary matter, however, identifies not only the elementary building blocks of matter, but also includes composites made from the constituents (atoms and molecules, for example). Such composites contain an interaction energy that holds the constituents together, and may constitute the bulk of the mass of the composite. As an example, to a great extent, the mass of an atom is simply the sum of the masses of its constituent protons, neutrons and electrons. However, digging deeper, the protons and neutrons are made up of quarks bound together by gluon fields (see dynamics of quantum chromodynamics) and these gluons fields contribute significantly to the mass of hadrons.^[59] In other words, most of what composes the "mass" of ordinary matter is due to the binding energy of quarks within protons and neutrons.^[60] For example, the sum of the mass of the three quarks in a nucleon is approximately 12.5 MeV/c², which is low compared to the mass of a nucleon (approximately 938 MeV/c²).^[56][61] The bottom line is that most of the mass of everyday objects comes from the interaction energy of its elementary components.

Smaller building blocks?[link]

The Standard Model groups matter particles into three generations, where each generation consists of two quarks and two leptons. The first generation is the up and down quarks, the electron and the electron neutrino; the second includes the charm and strange quarks, the muon and the muon neutrino; the third generation consists of the top and bottom quarks and the tau and tau neutrino.^[62] The most natural explanation for this would be that quarks and leptons of higher generations are excited states of the first generations. If this turns out to be the case, it would imply that quarks and leptons are composite particles, rather than elementary particles.^[63]

Structure[link]

In particle physics, fermions are particles which obey Fermi–Dirac statistics. Fermions can be elementary, like the electron, or composite, like the proton and the neutron. In the Standard Model there are two types of elementary fermions: quarks and leptons, which are discussed next.

Quarks[link]

Quarks are particles of spin-¹⁄₂, implying that they are fermions. They carry an electric charge of −¹⁄₃ e (down-type quarks) or +²⁄₃ e (up-type quarks). For comparison, an electron has a charge of −1 e. They also carry colour charge, which is the equivalent of the electric charge for the strong interaction. Quarks also undergo radioactive decay, meaning that they are subject to the weak interaction. Quarks are massive particles, and therefore are also subject to gravity.

Baryonic matter[link]

Baryons are strongly interacting fermions, and so are subject to Fermi-Dirac statistics. Amongst the baryons are the protons and neutrons, which occur in atomic nuclei, but many other unstable baryons exist as well. The term baryon is usually used to refer to triquarks — particles made of three quarks. "Exotic" baryons made of four quarks and one antiquark are known as the pentaquarks, but their existence is not generally accepted.

Baryonic matter is the part of the universe that is made of baryons (including all atoms). This part of the universe does not include dark energy, dark matter, black holes or various forms of degenerate matter, such as compose white dwarf stars and neutron stars. Microwave light seen by Wilkinson Microwave Anisotropy Probe (WMAP), suggests that only about 4.6% of that part of the universe within range of the best telescopes (that is, matter that may be visible because light could reach us from it), is made of baryionic matter. About 23% is dark matter, and about 72% is dark energy.^[65]

Degenerate matter[link]

In physics, degenerate matter refers to the ground state of a gas of fermions at a temperature near absolute zero.^[66] The Pauli exclusion principle requires that only two fermions can occupy a quantum state, one spin-up and the other spin-down. Hence, at zero temperature, the fermions fill up sufficient levels to accommodate all the available fermions, and for the case of many fermions the maximum kinetic energy called the Fermi energy and the pressure of the gas becomes very large and dependent upon the number of fermions rather than the temperature, unlike normal states of matter.

Degenerate matter is thought to occur during the evolution of heavy stars.^[67] The demonstration by Subrahmanyan Chandrasekhar that white dwarf stars have a maximum allowed mass because of the exclusion principle caused a revolution in the theory of star evolution.^[68]

Degenerate matter includes the part of the universe that is made up of neutron stars and white dwarfs.

Strange matter[link]

Strange matter is a particular form of quark matter, usually thought of as a 'liquid' of up, down, and strange quarks. It is to be contrasted with nuclear matter, which is a liquid of neutrons and protons (which themselves are built out of up and down quarks), and with non-strange quark matter, which is a quark liquid containing only up and down quarks. At high enough density, strange matter is expected to be color superconducting. Strange matter is hypothesized to occur in the core of neutron stars, or, more speculatively, as isolated droplets that may vary in size from femtometers (strangelets) to kilometers (quark stars).

Two meanings of the term "strange matter"[link]

In particle physics and astrophysics, the term is used in two ways, one broader and the other more specific.

1. The broader meaning is just quark matter that contains three flavors of quarks: up, down, and strange. In this definition, there is a critical pressure and an associated critical density, and when nuclear matter (made of protons and neutrons) is compressed beyond this density, the protons and neutrons dissociate into quarks, yielding quark matter (probably strange matter).
2. The narrower meaning is quark matter that is more stable than nuclear matter. The idea that this could happen is the "strange matter hypothesis" of Bodmer^[69] and Witten.^[70] In this definition, the critical pressure is zero: the true ground state of matter is always quark matter. The nuclei that we see in the matter around us, which are droplets of nuclear matter, are actually metastable, and given enough time (or the right external stimulus) would decay into droplets of strange matter, i.e. strangelets.

Leptons[link]

Leptons are particles of spin-¹⁄₂, meaning that they are fermions. They carry an electric charge of −1 e (charged leptons) or 0 e (neutrinos). Unlike quarks, leptons do not carry colour charge, meaning that they do not experience the strong interaction. Leptons also undergo radioactive decay, meaning that they are subject to the weak interaction. Leptons are massive particles, therefore are subject to gravity.

Phases[link]

Phase diagram for a typical substance at a fixed volume. Vertical axis is Pressure, horizontal axis is Temperature. The green line marks the freezing point (above the green line is solid, below it is liquid) and the blue line the boiling point (above it is liquid and below it is gas). So, for example, at higher T, a higher P is necessary to maintain the substance in liquid phase. At the triple point the three phases; liquid, gas and solid; can coexist. Above the critical point there is no detectable difference between the phases. The dotted line shows the anomalous behavior of water: ice melts at constant temperature with increasing pressure.^[73]

In bulk^{[disambiguation needed ]}, matter can exist in several different forms, or states of aggregation, known as phases,^[74] depending on ambient pressure, temperature and volume.^[75] A phase is a form of matter that has a relatively uniform chemical composition and physical properties (such as density, specific heat, refractive index, and so forth). These phases include the three familiar ones (solids, liquids, and gases), as well as more exotic states of matter ( such as plasmas, superfluids, supersolids, Bose–Einstein condensates, ...). A fluid may be a liquid, gas or plasma. There are also paramagnetic and ferromagnetic phases of magnetic materials. As conditions change, matter may change from one phase into another. These phenomena are called phase transitions, and are studied in the field of thermodynamics. In nanomaterials, the vastly increased ratio of surface area to volume results in matter that can exhibit properties entirely different from those of bulk material, and not well described by any bulk phase (see nanomaterials for more details).

Phases are sometimes called states of matter, but this term can lead to confusion with thermodynamic states. For example, two gases maintained at different pressures are in different thermodynamic states (different pressures), but in the same phase (both are gases).

Antimatter[link]

In particle physics and quantum chemistry, antimatter is matter that is composed of the antiparticles of those that constitute ordinary matter. If a particle and its antiparticle come into contact with each other, the two annihilate; that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc². These new particles may be high-energy photons (gamma rays) or other particle–antiparticle pairs. The resulting particles are endowed with an amount of kinetic energy equal to the difference between the rest mass of the products of the annihilation and the rest mass of the original particle-antiparticle pair, which is often quite large.

Antimatter is not found naturally on Earth, except very briefly and in vanishingly small quantities (as the result of radioactive decay, lightning or cosmic rays). This is because antimatter which came to exist on Earth outside the confines of a suitable physics laboratory would almost instantly meet the ordinary matter that Earth is made of, and be annihilated. Antiparticles and some stable antimatter (such as antihydrogen) can be made in tiny amounts, but not in enough quantity to do more than test a few of its theoretical properties.

There is considerable speculation both in science and science fiction as to why the observable universe is apparently almost entirely matter, and whether other places are almost entirely antimatter instead. In the early universe, it is thought that matter and antimatter were equally represented, and the disappearance of antimatter requires an asymmetry in physical laws called the charge parity (or CP symmetry) violation. CP symmetry violation can be obtained from the Standard Model,^[76] but at this time the apparent asymmetry of matter and antimatter in the visible universe is one of the great unsolved problems in physics. Possible processes by which it came about are explored in more detail under baryogenesis.

Other types of matter[link]

Pie chart showing the fractions of energy in the universe contributed by different sources. Ordinary matter is divided into luminous matter (the stars and luminous gases and 0.005% radiation) and nonluminous matter (intergalactic gas and about 0.1% neutrinos and 0.04% supermassive black holes). Ordinary matter is uncommon. Modeled after Ostriker and Steinhardt.^[77] For more information, see NASA.

Ordinary matter, in the quarks and leptons definition, constitutes about 4% of the energy of the observable universe. The remaining energy is theorized to be due to exotic forms, of which 23% is dark matter^[78][79] and 73% is dark energy.^[80][81]

The observed curve of speed of rotation is blue. The predicted curve based upon stellar mass and gas in the Milky Way is red. The difference is due to dark matter or perhaps a modification of the law of gravity.^[82][83][84] Scatter in observations is indicated roughly by gray bars.

Dark matter[link]

In astrophysics and cosmology, dark matter is matter of unknown composition that does not emit or reflect enough electromagnetic radiation to be observed directly, but whose presence can be inferred from gravitational effects on visible matter.^[11][85] Observational evidence of the early universe and the big bang theory require that this matter have energy and mass, but is not composed of either elementary fermions (as above) OR gauge bosons. The commonly accepted view is that most of the dark-matter is non-baryonic in nature.^[11] As such, it is composed of particles as yet unobserved in the laboratory. Perhaps they are supersymmetric particles,^[86] which are not Standard Model particles, but relics formed at very high energies in the early phase of the universe and still floating about.^[11]

Dark energy[link]

In cosmology, dark energy is the name given to the antigravitating influence that is accelerating the rate of expansion of the universe. It is known not to be composed of known particles like protons, neutrons or electrons, nor of the particles of dark matter, because these all gravitate.^[87][88]

Fully 70% of the matter density in the universe appears to be in the form of dark energy. Twenty-six percent is dark matter. Only 4% is ordinary matter. So less than 1 part in 20 is made out of matter we have observed experimentally or described in the standard model of particle physics. Of the other 96%, apart from the properties just mentioned, we know absolutely nothing.

— Lee Smolin: The Trouble with Physics, p. 16

Exotic matter[link]

Exotic matter is a hypothetical concept of particle physics. It covers any material which violates one or more classical conditions or is not made of known baryonic particles. Such materials would possess qualities like negative mass or being repelled rather than attracted by gravity.

William Martin "Billy" Joel (born May 9, 1949) is an American pianist, singer-songwriter, and composer. Since releasing his first hit song, "Piano Man," in 1973, Joel has become the sixth best-selling recording artist and the third best-selling solo artist in the United States, according to the RIAA.^[3]

Joel had Top 40 hits in the 1970s, 1980s, and 1990s, achieving 33 Top 40 hits in the United States, all of which he wrote himself. He is also a six-time Grammy Award winner, a 23-time Grammy nominee and has sold over 150 million records worldwide.^[4] He was inducted into the Songwriter's Hall of Fame (1992), the Rock and Roll Hall of Fame (1999), the Long Island Music Hall of Fame (2006), and the Hit Parade Hall of Fame (2009). In 2008, Billboard magazine released a list of the Hot 100 All-Time Top Artists to celebrate the US singles chart's 50th anniversary, with Billy Joel positioned at No. 23. With the exception of the 2007 songs "All My Life" and "Christmas in Fallujah," Joel stopped recording pop/rock material after 1993's River of Dreams, but he continued to tour extensively until 2010.^[5]

Early life[link]

Joel was born in the Bronx^[1] and raised in Hicksville, New York. His father, Howard (born Helmuth), was born in Germany, the son of German merchant and manufacturer Karl Amson Joel, who, after the advent of the Nazi regime, emigrated to Switzerland and later to the United States. Billy Joel's mother, Rosalind Nyman, was born in England to Philip and Rebecca Nyman. Both Joel's parents were Jewish. They divorced in 1960, and his father moved to Vienna, Austria. Billy has a sister, Judith Joel, and a half-brother, Alexander Joel, who is an acclaimed classical conductor in Europe and currently chief musical director of the Staatstheater Braunschweig.^[6]

Joel's father was an accomplished classical pianist. Billy reluctantly began piano lessons at an early age, at his mother's insistence; his teachers included the noted American pianist Morton Estrin^[7] and musician/songwriter Timothy Ford. His interest in music, rather than sports, was a source of teasing and bullying in his early years. (He has said in interviews that his piano instructor also taught ballet. Her name was Frances Neiman, and she was a Juilliard trained musician. She gave both classic piano and ballet lessons in the studio attached to the rear of her house, leading neighborhood bullies to mistakenly think he was learning to dance.)^{[citation needed]} As a teenager, Joel took up boxing so that he would be able to defend himself. He boxed successfully on the amateur Golden Gloves circuit for a short time, winning twenty-two bouts, but abandoned the sport shortly after having his nose broken in his twenty-fourth boxing match.^[8]

Joel attended Hicksville High School with the class of 1967. However, he did not graduate. At the time, he was helping his single mother make ends meet by playing at a piano bar, and this interfered with his school attendance.^[9] After his senior year, he still was short of the total number of credits he needed to graduate. Rather than attend summer school, Joel decided to quit high school without a diploma in order to begin a career in music. Joel recounted, "I told them, 'To hell with it. If I'm not going to Columbia University, I'm going to Columbia Records and you don't need a high school diploma over there'."^[10] Columbia did, in fact, become the label that eventually signed him. In 1992, he submitted essays to the school board and was awarded his diploma at Hicksville High's annual graduation ceremony, 25 years after he had left.^[11]

Music career[link]

Early career[link]

Upon seeing The Beatles on The Ed Sullivan Show in 1964, Joel decided to pursue a full-time musical career, and set about finding a local Long Island band to join. Eventually he founded the Echoes, a group that specialized in British Invasion covers. The Echoes became a popular New York attraction, which convinced him to leave high school to become a professional musician. He began playing for the Echoes when he was 14 years old.^[12]

Joel began playing recording sessions with the Echoes in 1965, when he was 16 years old. Joel played piano on several recordings produced by Shadow Morton, including (as claimed by Joel, but denied by songwriter Ellie Greenwich) the Shangri-Las' Leader of the Pack,^[13] as well as several records released through Kama Sutra Productions. During this time, the Echoes started to play numerous late-night shows.

Later, in 1965, the Echoes changed their name to the Emeralds and then to the Lost Souls. For two years, Joel played sessions and performed with the Lost Souls. In 1967, he left that band to join the Hassles, a Long Island band that had signed a contract with United Artists Records. Over the next year and a half, they released The Hassles in 1967, Hour of the Wolf in 1968, and four singles, all of which failed commercially. Following The Hassles' demise in 1969, he formed the duo Attila with Hassles drummer Jon Small. Attila released their eponymous debut album in July 1970, and disbanded the following October. The reason for the group's break-up has been attributed to Joel's affair with Small's wife, Elizabeth, whom Joel eventually married.^[14]

[edit] Cold Spring Harbor

Joel signed his first solo record contract with Artie Ripp's Family Productions, and subsequently recorded his first solo album. Cold Spring Harbor (a reference to the Long Island town of the same name), was released in 1971. However, Ripp mastered and released the album at the wrong speed, resulting in Joel's voice sounding a semitone too high. In addition, the onerous terms of Ripp's Family Productions contract also guaranteed Joel very little money from the sales of his albums.

Popular cuts such as "She's Got a Way" and "Everybody Loves You Now" were originally released on this album, although they did not gain much attention until released as live performances in 1981 on Songs in the Attic. Since then, they have become favorite concert numbers. Cold Spring Harbor gained a second chance on the charts in 1984, when Columbia reissued the album after slowing it down to the correct speed. The album reached #158 in the US and #95 in the UK nearly a year later.

Joel gigged locally in New York City in the fall of 1971 and moved out to Los Angeles early in 1972, adopting the stage name Bill Martin.^[15] While in California he did a six month gig in The Executive Room piano bar on Wilshire Boulevard. It was there he composed his signature hit "Piano Man" about the various patrons of the lounge. Subsequently he toured with his band members (Rhys Clark on drums, Al Hertzberg on guitar, and Larry Russell on bass) until the end of June 1972 throughout the US and Puerto Rico, opening for headliners such as J. Geils Band, The Beach Boys and Taj Mahal. At the Mar y sol festival in Puerto Rico, he electrified the crowd and got a big boost for his career.^[16]

In addition Philadelphia radio station WMMR-FM started playing a concert recording of Joel performing his "Captain Jack," which became an underground hit on the East Coast. Herb Gordon, an executive of Columbia Records, heard Joel's music and made his company aware of Joel's talent. Joel signed a recording contract with Columbia in 1972 and moved to Los Angeles. He lived there for three years (and has since declared that those three years were a big mistake),^[17] returning to New York City in 1975.

Early Columbia years: 1973–1976[link]

Joel's experiences in Los Angeles connected him with record company executives, who bought out his contract with Ripp under the condition that the Family Productions logo be displayed alongside the Columbia logo for the next ten albums, and Family Productions would receive a 25-cent royalty on every Joel album sold. The president of CBS/Columbia Records at the time, Walter Yetnikoff, bought back the rights to Joel's songs from Artie Ripp in the late 1970s, giving the rights to the songs back to Joel as a birthday gift.^[18][19] However, Yetnikoff notes in the documentary film The Last Play at Shea that he ultimately had to threaten Ripp in order to finalize the deal for the song rights. So, although Ripp continued to make money on Joel's albums, Joel at least had ownership of his songs through the help of the president of his new record label.

The stand-out track from his first album for Columbia Records, Piano Man, was the title track, which, despite only making it to #25 on the Billboard Hot 100, stands as Joel's signature song (he ends nearly all of his concerts with it).

Joel's touring band changed as well in 1973. Don Evans replaced Al Hertzberg on guitar, and Patrick McDonald took over the bass position previously held by Larry Russell, and was then replaced in late 1974 by Doug Stegmeyer, who remained with Joel until 1989. Rhys Clark returned as drummer, Tom Whitehorse on banjo and pedal steel and then Johnny Almond on sax and keyboards rounded out the band. Joel's infectious spirit and talent galvanized the band into a tight performing unit, touring the U.S. and Canada extensively and appearing on the popular music shows of the day. Joel's songwriting was now attracting more attention; Helen Reddy recorded "You're My Home" (from Piano Man) in 1974.

Joel remained in Los Angeles to write Streetlife Serenade, his second album on the Columbia label. It was around this time that Jon Troy, an old friend from the New York neighborhood of Bedford-Stuyvesant, acted as Joel's manager although he would soon be replaced by Joel's wife Elizabeth.^[20] References to both suburbia and the inner city pepper the album.

The stand-out track on the album is "The Entertainer", a #34 hit in the U.S. which picks up thematically where "Piano Man" left off. Joel was upset that "Piano Man" had been significantly edited down to make it more radio-friendly, and in "The Entertainer," he refers to the edit with sarcastic lines such as "If you're gonna have a hit, you gotta make it fit, so they cut it down to 3:05", alluding to shortening of singles for radio play, as compared with the longer versions that appear on albums. Although Streetlife Serenade is often considered one of Joel's weaker albums (Joel has confirmed his distaste for the album), it nevertheless contains some notable tracks, including the title track, "Los Angelenos" and the instrumental "Root Beer Rag", which was a staple of his live set in the 1970s and was resurrected frequently in 2007 and 2008. Streetlife Serenade also marks the beginning of a more confident vocal style on Joel's part.

In late 1975, he played piano and organ on several tracks on Bo Diddley's The 20th Anniversary of Rock 'n' Roll all-star album.

Disenchanted with the L.A. music scene, Joel returned to New York in 1976. There he recorded Turnstiles, for which he used his own hand-picked musicians in the studio for the first time, and also adopted a more hands-on role. Songs were initially recorded at Caribou Ranch with members of Elton John's band, and produced by famed Chicago producer James William Guercio, but Joel was dissatisfied with the results. The songs were re-recorded in New York, and Joel took over, producing the album himself.

The minor hit "Say Goodbye to Hollywood" echoed the Phil Spector sound, and was covered by Ronnie Spector (in a 2008 radio interview, Joel said he does not perform "Say Goodbye to Hollywood" in his live shows anymore because it is in too high a key and "shreds" his vocal cords.) The album also featured the song "New York State of Mind", a bluesy, jazzy epic that has become one of Joel's signature songs, and which was later covered by fellow Columbia labelmates Barbra Streisand, on her 1977 Streisand Superman album, and as a duet with Tony Bennett, on his 2001 Playing with My Friends: Bennett Sings the Blues album. Other songs on the album include "Summer, Highland Falls", "Miami 2017 (Seen the Lights Go Out on Broadway)" and "Say Goodbye to Hollywood", which became a Top 40 hit in 1981 in a live version. Songs such as the powerful "Prelude/Angry Young Man" have become a mainstay of his concerts.

[edit] The Stranger and 52nd Street

For The Stranger, Columbia Records teamed Joel with producer Phil Ramone. The album was released in September 1977, and yielded four Top-25 hits on the Billboard charts in the US: "Just the Way You Are" (#3), "Movin' Out (Anthony's Song)" (#17), "Only the Good Die Young" (#24), and "She's Always a Woman" (#17). Album sales exceeded Columbia's previous top-selling album, Simon & Garfunkel's Bridge Over Troubled Water,^[21] and was certified multi-platinum. His first-ever Top Ten album, it reached #2 on the charts. Ramone subsequently produced every Billy Joel studio release up to Storm Front, initially released in 1989. The Stranger also featured "Scenes from an Italian Restaurant", an album-oriented rock classic, which has become one of his best-known songs.

The Stranger netted Joel Grammy awards for Record of the Year and Song of the Year, for "Just the Way You Are", which was written as a gift to his wife Elizabeth. He received a late night phone call to his hotel room in Paris (he was on tour) in February 1979, letting him know he had won in both categories.^[22]

Joel faced high expectations on his next album. 52nd Street was named after the famous street of the same name which hosted many of the world's premier jazz venues and performers throughout the 1930s, 1940s, and 1950s. Fans purchased over seven million copies on the strength of the hits "My Life" (#3), "Big Shot" (#14), and "Honesty" (#24). This helped 52nd Street become Joel's first #1 album. "My Life" eventually became the theme song for a new US television sitcom, Bosom Buddies, which featured actor Tom Hanks in one of his earliest roles. The album won Grammys for Best Pop Vocal Performance, Male and Album of the Year. 52nd Street was the first album to be released on compact disc when it went on sale alongside Sony's CD player CDP-101 on October 1, 1982, in Japan.^[23]

Despite the publicity photos and album cover showing Joel holding a trumpet, he does not play the instrument on the album, though two tracks on the album do feature some well-known jazz trumpeters. Freddie Hubbard plays two solos on "Zanzibar" and Jon Faddis joins Michael Brecker and Randy Brecker in the horn section for "Half a Mile Away".

In 1979, Joel traveled to Havana, Cuba, to participate in the historic Havana Jam festival that took place between March 2–4, alongside Rita Coolidge, Kris Kristofferson; Stephen Stills, the CBS Jazz All-Stars, the Trio of Doom, Fania All-Stars, Billy Swan, Bonnie Bramlett, Mike Finnegan, Weather Report, plus an array of Cuban artists such as Irakere, Pacho Alonso, Tata Güines and Orquesta Aragón.^[24] His performance is captured on Ernesto Juan Castellanos's documentary Havana Jam '79.

Early 1980s[link]

The success of his piano-driven ballads like "Just the Way You Are," "She's Always a Woman" and "Honesty" never sat well with Joel, as many critics were quick to slap the "balladeer" tag on him. With Glass Houses, he attacked the new wave popularity with aplomb and delivered several harder-edged songs custom made for the live shows in arenas and stadiums he was by then playing almost exclusively. The front cover showed Joel's real-life modern glass house. The album spent 6 weeks at #1 on the Billboard chart and yielded such hits as "You May Be Right" (used as the theme song, covered by Southside Johnny, for the CBS mid-1990s sitcom Dave's World) (#7, May 1980), "Close To The Borderline" (B-side of the "You May Be Right" single), "Don't Ask Me Why" (#19, September 1980), "Sometimes a Fantasy" (#36, November 1980) and "It's Still Rock and Roll to Me", which became Joel's first Billboard #1 song (for two weeks) in July 1980. "It's Still Rock and Roll to Me" spent 11 weeks in the top 10 of the Billboard Hot 100 and was the 7th biggest hit of 1980 according to American Top 40. Glass Houses won the Grammy for Best Rock Vocal Performance, Male. It would also win the American Music Award for Favorite Album, Pop/Rock category. The album's closing song, "Through The Long Night", (B-side of the "It's Still Rock & Roll to Me" single) was a lullaby that featured Joel harmonizing with himself in a song he says was inspired by The Beatles' "Yes It Is."^[16]

His next release, Songs in the Attic, was composed of live performances of less well-known songs from the beginning of his career. It was recorded during larger US arenas and intimate night club shows in June and July 1980. This release introduced many fans, who discovered Joel when The Stranger became a smash in 1977, to many of his earlier compositions. The album reached #8 on the Billboard chart and produced two hit singles: "Say Goodbye to Hollywood" (#17), and "She's Got a Way" (#23). It sold over 3 million copies. Though not as successful as some of his previous albums, the album was still considered a success by Joel.^[16]

The next wave of Joel's career commenced with the recording of The Nylon Curtain. Joel's songwriting on this album, which is considered his most audacious and ambitious by many critics,^[who?], and cited by Joel himself to the present day as his favorite of his works,^{[citation needed]} was heavily influenced by the Beatles.

Work began on The Nylon Curtain in the fall of 1981. Joel was involved in a serious motorcycle accident on Long Island on April 15, 1982, which delayed the completion of the album a few weeks. He embarked on a brief tour in support of the album, during which his first video special, Live from Long Island, was recorded at the Nassau Veterans Memorial Coliseum in Uniondale, New York on December 30, 1982. It was originally broadcast on HBO in 1983 before it became available on VHS.^[25]

The Nylon Curtain went to #7 on the charts, partially due to heavy airplay on MTV for the videos to the singles "Allentown" and "Pressure". "Allentown" spent six weeks at a peak position of #17 on the Billboard Hot 100, making it one of the most-played radio songs of 1982, pushing it into 1983's year-end Top 70, and making it the most successful song from The Nylon Curtain album, besting "Pressure". which peaked at #20 (where it resided for three weeks) and "Goodnight Saigon" which reached #56 on U.S. charts.^[26]

[edit] Christie Brinkley, An Innocent Man, and The Bridge

The album An Innocent Man was compiled as a tribute to the rock and roll music of the 1950s and 1960s, and also resulted in Joel's second Billboard #1 hit, "Tell Her About It", which was the first single off the album in the summer of 1983. The album itself reached #4 on the charts and #2 in UK. It also boasted 6 top-30 singles, the most of any album in Joel's catalog. At the time that the album came, WCBS-FM began playing "The Longest Time" both in regular rotation and on the Doo Wop Shop. Many fans wanted this to be the next single released in the fall, but that October, "Uptown Girl", Joel's next big hit from An Innocent Man, would be released. According to numerous interviews with Joel, this song was initially written about his relationship with his then-girlfriend Elle Macpherson, but it ended up also becoming about his soon-to-be wife Christie Brinkley (both women being two of the most famous supermodels of the 1980s).^[27][28] The song became a worldwide hit upon its release, #3 in the U.S. and Joel's sole #1 in the United Kingdom. Also, the James Brown-inspired song "Easy Money" would be featured in the 1983 Rodney Dangerfield film of the same name.^[29]

In December the title song, "An Innocent Man", would be released as a single and would peak at #10 in the U.S. and #8 in the UK, early in 1984. That March, "The Longest Time" would finally be released as a single, peaking at #14 on the Hot 100 and #1 on the Adult Contemporary chart. That summer, "Leave a Tender Moment Alone" would be released and hit #27 while "Keeping the Faith" would peak at #18 in January 1985. In the video for "Keeping the Faith", Christie Brinkley also plays the "redhead girl in a Chevrolet". An Innocent Man was also nominated for the Album of the Year Grammy, but lost to Michael Jackson's Thriller.

Joel would participate in the USA For Africa We Are The World project in 1985, capping off a series of successful singles for Joel.

Following the success of An Innocent Man, Joel had been approached to release an album of his most successful singles. This was not the first time this topic had come up, but Joel had initially considered "Greatest Hits" albums as marking the end of one's career. This time, he agreed, and Greatest Hits Vol. 1 and 2 was released as a 4-sided album and 2-CD set, with the songs in sequence of when they were released. The new songs "You're Only Human (Second Wind)" and "The Night Is Still Young" were recorded and released as singles to support the album; both reached the top 40, peaking at #9 and #34, respectively.

Billy Joel live on November 7, 2006

Greatest Hits was highly successful and has since been certified double diamond by the RIAA for over 11.5 million copies (23 million units) sold. To date it is tied for the third best selling album in American music history according to the RIAA.

Coinciding with the Greatest Hits album release, Joel released a 2-volume Video Album that was a compilation of the promotional videos he had recorded from 1977 to the present time. Along with videos for the new singles off the Greatest Hits album, Joel also recorded a video for his first hit, "Piano Man", for this project.

Though it broke into the Top Ten, The Bridge was not a success in relation to some of Joel's other albums, but it yielded the hits "A Matter of Trust" and "Modern Woman" from the film Ruthless People, a dark comedy from the directors of Airplane! (both #10). In a departure from his "piano man" persona, Joel is shown in its video playing a Les Paul-autographed Gibson guitar. The ballad "This is the Time" also charted, peaking at #18, and has been a favorite on the prom circuit ever since. The reason "Modern Woman" has been left off many of Joel's compilation sets (the exception appears to be My Lives) is that he has since said in interviews he does not care for the song.^{[citation needed]}

On November 18, 1986, an extended version of the song "Big Man On Mulberry Street" was used on a Season 3 episode of Moonlighting. The episode itself was also titled "Big Man on Mulberry Street." In a dream sequence, Maddie Hayes envisions David Addison with his ex-wife. An extra horn solo was added to the song.

The Bridge was also Joel's last album to carry the Family Productions logo, finally severing his ties with Artie Ripp. Joel has also stated in many interviews, most recently in a 2008 interview in Performing Songwriter magazine, that he does not think The Bridge is a good album.

Shortly after The Bridge tour ended in late 1987, Joel completed voice work on Disney's Oliver & Company, released in 1988, a loose adaptation of the Charles Dickens novel Oliver Twist. Joel brought both his acting and musical talents to the film as Dodger. For the film, Joel recorded a song titled "Why Should I Worry?" Critics were generally positive toward the film, and pointed to Joel's acting contribution as one of its highlights, despite it being his first acting job. In interviews, Joel explained that he took the job due to his love of Disney cartoons as a child.

Trip to the Soviet Union[link]

In October 1986, Joel and his handlers started planning a trip to the Soviet Union. He became one of the first American rock acts to play there since the Berlin Wall went up, a fact not lost on history buff Joel.^[30] There were live performances at indoor arenas in Moscow, Leningrad and Tbilisi. Joel and his family (including young daughter Alexa) and his full touring band made the trip in August 1987. The entourage was filmed for television and video to offset the cost of the trip, and the concerts were simulcast on radio around the world.

Most of that audience took a long while to warm up to Joel's energetic show, something that never had happened in other countries he had performed in. According to Joel, each time the fans were hit with the bright lights, anybody who seemed to be enjoying themselves froze. In addition, people who were "overreacting" were removed by security.^[31]

The album КОНЦЕРТ (Russian for "Concert") was released in October 1987. Singer Peter Hewlitt was brought in to hit the high notes on his most vocally challenging songs, like "An Innocent Man." Joel also did versions of The Beatles' classic "Back in the U.S.S.R." and Bob Dylan's "The Times They Are a-Changin'". It has been estimated that Joel lost more than $1 million of his own money on the trip and concerts, but he has said the goodwill he was shown there was well worth it.^[16]

[edit] Storm Front and River of Dreams

The release of the album Storm Front coincided with major changes in Joel's career and inaugurated a period of serious upheaval in his business affairs. In August 1989, just before the album was released, Joel fired his manager (and former brother-in-law) Frank Weber after an audit revealed major discrepancies in Weber's accounting. Joel subsequently sued Weber for $90 million, claiming fraud and breach of fiduciary duty and in January 1990 he was awarded $2 million in a partial judgement against Weber; in April, the court dismissed a $30 million countersuit filed by Weber.^[32]

The first single for the album "We Didn't Start the Fire", was released in September 1989 and it became Joel's third and most recent US #1 hit, spending two weeks at the top; it was also Billboard's second-last #1 single of the 1980s. Storm Front was released in October, and it eventually became Joel's first #1 album since Glass Houses, nine years earlier. Storm Front was Joel's first album since Turnstiles to be recorded without Phil Ramone as producer. For this album, he wanted a new sound, and worked with Mick Jones of Foreigner fame. Joel also revamped his backing band, firing everyone, save drummer Liberty DeVitto, guitarist David Brown, and saxophone player Mark Rivera, and bringing in new faces, including talented multi-instrumentalist Crystal Taliefero. Storm Front's second single, "I Go to Extremes" made it to #6 in early 1990. The album was also notable for its song "Leningrad", written after Joel met a clown in the Soviet city of that name during his tour in 1987, and "The Downeaster Alexa", written to underscore the plight of fishermen on Long Island who are barely able to make ends meet. Another well-known single from the album is the ballad "And So It Goes" (#37 in late 1990). The song was originally written in 1983, around the time Joel was writing songs for An Innocent Man; but "And So It Goes" did not fit that album's retro theme, so it was held back until Storm Front. Joel said in a 1996 Masterclass session in Pittsburgh that Storm Front was a turbulent album and that "And So It Goes," as the last song on the album, portrayed the calm and tranquility that often follows a violent thunderstorm.

In the summer of 1992, Joel filed another $90 million lawsuit against his former lawyer Allen Grubman, alleging a wide range of offenses including fraud, breach of fiduciary responsibility, malpractice and breach of contract^[33] but the case was eventually settled out of court for an undisclosed sum.^[34]

Joel started work on River of Dreams in 1992 and finished the album in early 1993. Its cover art was a colorful painting by Christie Brinkley that was a series of scenes from each of the songs on the album. The eponymous first single was the last top 10 hit Joel has penned to date, reaching #3 on the Billboard Hot 100 & ranking at #21 on Billboard's 1993 year-end Hot 100 chart. In addition to the title track, the album includes the hits "All About Soul" (with Color Me Badd on backing vocals) and "Lullabye (Goodnight, My Angel)", written for his daughter, Alexa. A radio remix version of "All About Soul" can be found on The Essential Billy Joel (2001), and a demo version appears on My Lives (2005). The song "The Great Wall of China" was written about his ex-manager Frank Weber and was a regular in the setlist for Joel's 2006 tour. "2000 Years" was prominent in the millennium concert at Madison Square Garden, December 31, 1999, and "Famous Last Words" closed the book on Joel's pop songwriting for more than a decade.

1994–2007[link]

On August 25, 1994, Joel and second wife Christie Brinkley divorced. On December 31, 1999, Joel performed at New York's Madison Square Garden. At the time, Joel said that it would be his last concert. The concert (dubbed The Night of the 2000 Years) ran for close to four hours and was later released as 2000 Years: The Millennium Concert.

1997's "To Make You Feel My Love" and "Hey Girl" both charted from Joel's Greatest Hits Volume III album. Joel wrote and recorded the song "Shameless" that was later covered by Garth Brooks and reached number 1 on Billboard's country charts. Joel performed with Brooks during his Central Park concert in 1997 with an estimated 980,000 people in attendance, the largest audience to attend a U.S. concert.^{[citation needed]} To add on to his achievements Joel was inducted into the Rock 'n Roll Hall of Fame in 1999.

In 2001, Joel released Fantasies & Delusions, a collection of classical piano pieces. All were composed by Joel and performed by Richard Joo. Joel often uses bits of these songs as interludes in live performances, and some of them are part of the score for the hit show Movin' Out. The album topped the classical charts at #1. Joel performed "New York State of Mind" live on September 21, 2001, as part of the America: A Tribute to Heroes benefit concert, and on October 20, 2001, along with "Miami 2017 (Seen the Lights Go Out on Broadway)", at the Concert for New York City in Madison Square Garden. That night, he also performed "Your Song" with Elton John.

In 2005, Columbia released a box set, My Lives, which is largely a compilation of demos, b-sides, live/alternate versions and even a few Top 40 hits. The compilation also includes the Umixit software, in which people can remix "Zanzibar", "Only the Good Die Young", "Keepin' The Faith", and live versions of "I Go to Extremes" and "Movin' Out (Anthony's Song)" with their PC. Also, a DVD of a show from the River of Dreams tour is included.

On January 7, 2006, Joel began a tour across the United States. Having not written, or at least released, any new songs in 13 years, he featured a sampling of songs from throughout his career, including major hits as well as obscure tunes like "Zanzibar" and "All for Leyna". His tour included an unprecedented 12 sold-out concerts over several months at Madison Square Garden in New York City. The singer's stint of 12 shows at Madison Square Garden broke a previous record set by New Jersey native Bruce Springsteen, who played 10 sold-out shows at the same arena. The record earned Joel the first retired number (12) in the arena owned by a non-athlete. This honor has also been given to Joel at the Wells Fargo Center (Philadelphia) (formerly the Wachovia Center) in Philadelphia where a banner in the colors of the Philadelphia Flyers is hung honoring Joel's 46 Philadelphia sold-out shows. He also had a banner raised in his honor for being the highest grossing act in the history of the Times Union Center (formerly the Knickerbocker Arena and Pepsi Arena) in Albany, New York. This honor was given to him as part of the April 17, 2007, show he did there. On June 13, 2006, Columbia released 12 Gardens Live, a double album containing 32 live recordings from a collection of the 12 different shows at Madison Square Garden during Joel's 2006 tour.

Joel visited the United Kingdom and Ireland for the first time in many years as part of the European leg of his 2006 tour. On July 31, 2006, he performed a free concert in Rome, with the Colosseum as the backdrop. Organizers estimated 500,000 people turned out for the concert, which was opened by Bryan Adams.^{[citation needed]}

Joel toured South Africa, Australia, Japan, and Hawaii in late 2006, and subsequently toured the Southeastern United States in February and March 2007 before hitting the Midwest in the spring of 2007. On January 3 of that year, news was leaked to the New York Post that Billy had recorded a new song with lyrics—this being the first new song with lyrics he'd written in almost 14 years.^[35] The song, titled "All My Life", was Joel's newest single (with second track "You're My Home", live from Madison Square Garden 2006 tour) and was released into stores on February 27, 2007.^[36] On February 4, Joel sang the national anthem for Super Bowl XLI, becoming the first to sing the national anthem twice at a Super Bowl. and on April 17, 2007, Joel was honored in Albany, New York, for his ninth concert at the Times Union Center. He is now holding the highest box office attendance of any artist to play at the arena. A banner was raised in his honor marking this achievement.

On December 1, 2007, Joel premiered his new song "Christmas in Fallujah."^[37] The song was performed by Cass Dillon, a new Long Island based musician, as Joel felt it should be sung by someone in a soldier's age range. The track was dedicated to servicemen based in Iraq. Joel wrote it in September 2007 after reading numerous letters sent to him from American soldiers in Iraq. "Christmas in Fallujah" is only the second pop/rock song released by Joel since 1993's River of Dreams. Proceeds from the song benefitted the Homes For Our Troops foundation.

2008–present[link]

On January 26, 2008, Joel performed with the Philadelphia Orchestra celebrating the 151st anniversary of the Academy of Music. Joel premiered his new classical piece titled, "Waltz No. 2 (Steinway Hall)". He also played many of his less well-known pieces with full orchestral backing, including the rarely performed Nylon Curtain songs "Scandinavian Skies" and "Where's the Orchestra?".

On March 10, 2008, Joel inducted his friend John Mellencamp into the Rock and Roll Hall of Fame in a ceremony at the Waldorf Astoria Hotel in New York City. During his induction speech, Joel said the following to Mellencamp:

Joel's staying power as a touring act continues to the present day. He sold out 10 concerts at the Mohegan Sun Casino in Uncasville, Connecticut from May to July 2008. Mohegan Sun honored him with a banner displaying his name and the number 10 to hang in the arena. On June 19, 2008, he played a concert at the grand re-opening of Caesars Windsor (formerly Casino Windsor) in Windsor, Ontario, Canada to an invite-only crowd for Casino VIPs. His mood was light, and joke-filled, even introducing himself as "Billy Joel's dad" and stating "you guys overpaid to see a fat bald guy." He also admitted that Canadian folk-pop musician Gordon Lightfoot was the musical inspiration for "She's Always A Woman".^[38]

On July 16, 2008, and July 18, 2008, Joel played the final concerts at Shea Stadium before its demolition. His guests included Tony Bennett, Don Henley, John Mayer, John Mellencamp, Steven Tyler, Roger Daltrey, Garth Brooks, and Paul McCartney. McCartney ended the show with a reference to his own performance there with the Beatles in 1965, the first major stadium concert of the rock and roll industry.^[39] The concerts were featured in the 2010 documentary film Last Play at Shea. The film was released on DVD on February 8, 2011. The CD and DVD of the show, Live at Shea Stadium were released on March 8, 2011.

On December 11, 2008, Joel recorded his own rendition of "Christmas in Fallujah" during a concert at Acer Arena in Sydney and released it as a live single in Australia only. It is the only official release of Joel performing "Christmas in Fallujah", as Cass Dillon sang on the 2007 studio recording and the handful of times the song was played live in 2007. Joel sang the song throughout his December 2008 tour of Australia.

On May 19, 2009, Joel's former drummer, Liberty DeVitto, filed a lawsuit in NYC claiming Joel and Sony Music owed DeVitto over 10 years of royalty payments. DeVitto has never been given songwriting credit on any of Joel's songs, but he claims that he helped write some of them.^[40] In April 2010, it was announced that Joel and DeVitto amicably resolved the lawsuit.^[41]

2011 re-releases[link]

2011 marks the 40th anniversary of the release of Joel's first album, Cold Spring Harbor. According to Billy Joel's website, in commemoration of this anniversary, "Columbia/Legacy Recordings will celebrate the occasion with a definitive reissue project of newly restored and expanded Legacy editions of the complete Billy Joel catalog, newly curated collections of rarities from the vaults, previously unavailable studio tracks and live performances, home video releases and more."^[42] The album Piano Man was re-released in a 2-disc Legacy edition in November 2011.^[42]

Face-to-Face tours[link]

Beginning in 1994, Joel toured extensively with Elton John on a series of "Face to Face" tours, making them the longest running and most successful concert tandem in pop music history.^[43] During these shows, the two have played their own songs, each other's songs and performed duets. They grossed over US $46 million in just 24 dates in their sold out^[44] 2003 tour. Joel and John resumed the Face to Face tour in March 2009^[44] and it ended again, at least for the time being, in March 2010 in Albany, NY at the Times Union Center. In February 2010, Joel denied rumors in the trade press that he canceled a summer 2010 leg of the tour, claiming there were never any dates booked and that he intended to take the year off.^[45] Joel told Rolling Stone magazine: "We’ll probably pick it up again. It’s always fun playing with him."

Other ventures[link]

In 1996, Joel merged his long-held love of boating^[46] with his desire for a second career. He formed, with Long Island boating businessman Peter Needham, the Long Island Boat Company.^[47]

In November 2010, Joel opened a shop on Oyster Bay, Long Island to manufacture custom-made, retro-styled motorcycles and accessories.^[48]

On March 22, 2011, Joel, as part of a fund raising event for impoverished children in the United States, performed with some of today's top teen artists, such as Justin Bieber, Selena Gomez, and Rebecca Black. He performed "Summer Highland Falls" with Justin Bieber as a cameo.^{[citation needed]}

In 2011, Joel announced that he was releasing an autobiography that he had written with Fred Schruers, titled The Book of Joel: A Memoir. The book was originally going to be released in June 2011, but in March 2011 Joel decided against publishing the book and officially cancelled his deal with HarperCollins. Rolling Stone noted, "HarperCollins acquired the book project for $3 million in 2008. [However,] Joel is expected to return his advance on that sum to the publisher."^[49] According to Billboard, "the HarperCollins book was billed as an 'emotional ride' that would detail the music legend's failed marriage to Christie Brinkley, as well as his battles with substance abuse."^[50] In explaining his decision to cancel the book's release, Joel stated, "It took working on writing a book to make me realize that I'm not all that interested in talking about the past, and that the best expression of my life and its ups and downs has been and remains my music."^[51]

Personal life[link]

Marriages, relationships, and family[link]

Joel married his business manager, Elizabeth Weber Small, on September 5, 1973. She was the former wife of his music partner, Jon Small, in the short-lived duo Attila. They divorced on July 20, 1982.

Joel mentioned in a television interview on the UK's Channel Five that he had dated Elle Macpherson in the 1980s prior to his marriage to Christie Brinkley. Joel has also said that the songs "This Night" and "And So It Goes" were written about his relationship with Macpherson.^[52]

Joel married Christie Brinkley on March 23, 1985. Their daughter, Alexa Ray Joel, was born December 29, 1985.^[53][54] Alexa was given the middle name of Ray after Ray Charles, one of Joel's musical idols.^[55] Joel and Brinkley divorced on August 25, 1994, although the couple remain friendly.

On October 2, 2004, Joel married 23-year-old Katie Lee. At the time of the wedding, Joel was 55. Joel's daughter, Alexa Ray, then 18, served as maid-of-honor. Joel's second wife, Christie Brinkley, attended the union and gave the couple her blessing. Lee works as a restaurant correspondent for the PBS show, George Hirsch: Living it Up!. In 2006, Katie Lee hosted Bravo's Top Chef. She did not return for a second season, instead going on tour with her husband. She then began writing a weekly column in Hamptons magazine, and became a field correspondent for the entertainment television show Extra. On June 17, 2009, both confirmed that they had split after five years of marriage.^[56]

Depression[link]

Joel battled depression for many years. In 1970, a career downturn and personal problems aggravated his condition. He left a suicide note (which inspired the lyrics to "Tomorrow Is Today") and attempted to commit suicide by drinking furniture polish, saying later, "I drank furniture polish. It looked tastier than bleach."^[16] His drummer assistant, Jon Small, rushed him to the hospital. Joel checked into Meadowbrook Hospital, where he was put on suicide watch and received treatment for depression.^[57] Joel later recorded "You're Only Human (Second Wind)" as a message to help prevent teen suicide.

Substance abuse treatment[link]

In 2002, Joel entered Silver Hill Hospital, a substance abuse and psychiatric center in New Canaan, Connecticut. In March 2005, he checked into the Betty Ford Center,^[58] where he spent 30 days for the treatment of alcohol-related problems.^[59]

Politics[link]

Although Joel has donated money to Democratic candidates running for office,^[60] he has never publicly affiliated himself with the Democratic Party. Although he isn't known for publicly endorsing political candidates, he did play a benefit with Bruce Springsteen to raise money for Barack Obama's presidential campaign in 2008.^[61] He has also played at benefit concerts that have helped raise funds for political causes. However, Joel has said about musicians endorsing political candidates, "People who pay for your tickets, I don't think they want to hear who you're going to vote for and how you think they should vote."^[62]

Religion[link]

Joel was born to non-observant Jewish parents and considers himself a cultural Jew.

During a 2010 interview on The Howard Stern Show, Joel referred to himself as an atheist.^[64]

Billy Joel receiving an Honorary Doctorate of Fine Arts from Syracuse University, May 14, 2006

Joel was inducted into the Rock and Roll Hall of Fame in Cleveland, Ohio in 1999. Joel was on the site selection committee for the Rock and Roll Hall of Fame board. Seven members of the committee voted for San Francisco and seven voted for Cleveland, Ohio, this was a tied vote so Billy Joel was the tie breaking vote, which gave Cleveland the hall in 1986.

Joel was also named MusiCares Person of the Year for 2002,^[67] an award given each year at the same time as the Grammy Awards. At the dinner honoring Joel, various artists performed versions of his songs including Nelly Furtado, Stevie Wonder, Jon Bon Jovi, Diana Krall, Rob Thomas and Natalie Cole.

Joel has banners in the rafters of the Times Union Center, Nassau Coliseum, Madison Square Garden, Mohegan Sun Arena in Uncasville, CT, Wells Fargo Center in Philadelphia, and Hartford Civic Center in Hartford. (Joel is erroneously cited as the first artist to perform a concert at Yankee Stadium in New York City; The Isley Brothers first performed there in 1969, and the Latin supergroup, The Fania All-Stars played and recorded live albums at the stadium during the 1970s.)

He has also sponsored the Billy Joel Visiting Composer Series at Syracuse University.^[68]

Joel is the only performing artist to have played both Yankee and Shea Stadiums, as well as Giants Stadium, Madison Square Garden, and Nassau Veterans Memorial Coliseum.
