Nuclear families typically centre on a married couple;[1] the nuclear family may have any number of children. There are differences in definition among observers; some definitions allow only biological children that are full-blood siblings,[2] while others allow for a stepparent and any mix of dependent children including stepchildren and adopted children.[3][4] Family structures of one married couple and their children were present in Western Europe and New England in the 17th century, influenced by church and theocratic governments.[5] With the emergence of proto-industrialization and early capitalism, the nuclear family became a financially viable social unit.[6] The term nuclear family first appeared in the early twentieth century. Alternative definitions have evolved to include family units headed by same-sex parents,[1] and perhaps additional adult relatives who take on a cohabiting parental role;[7] in this latter case it also receives the name of conjugal family.[1] In its most common usage, the term nuclear family refers to a household consisting of a father, a mother and their children[12] all in one household dwelling.[9] The late George Murdock, an influential observer of families, offered an early description: The family is a social group characterized by common residence, economic cooperation and reproduction. It contains adults of both sexes, at least two of whom maintain a socially approved sexual relationship, and one or more children, own or adopted, of the sexually cohabiting adults.[13] Many individuals are part of two nuclear families in their lives: the family of origin in which they are offspring, and the family of procreation in which they are a parent.[14] Nuclear fission From Wikipedia, the free encyclopedia (Redirected from Splitting the atom) "Splitting the atom" redirects here. For the EP, see Splitting the Atom. An induced fission reaction. A neutron is absorbed by a uranium-235 nucleus, turning it briefly into an excited uranium-236 nucleus, with the excitation energy provided by the kinetic energy of the neutron plus the forces that bind the neutron. "prompt gamma rays" (not shown) are produced, as well.

The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission of heavy elements was discovered on December 17, 1938 by German Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch. Frisch named the process by analogy with biological fission of living cells. It is an exothermic reaction which can release large amounts of energy both as electromagnetic radiation and as kinetic energy of the fragments (heating the bulk material where fission takes place). In order for fission to produce energy, the total binding energy of the resulting elements must be less negative (higher energy) than that of the starting element. The Titan II Intercontinental ballistic missile (ICBM) carried a 9 Mt W53 warhead, one of the most powerful nuclear weapons fielded by the United States during the Cold War. Nuclear warfare (sometimes atomic warfare or thermonuclear warfare) is a military conflict or political strategy in which nuclear weaponry is used to inflict damage on the enemy.
