In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.
Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.
An engineer is a practitioner of engineering, concerned with applying scientific knowledge, mathematics, and ingenuity to develop solutions for technical, societal and commercial problems. Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word engineer is derived from the Latin words ingeniare ("to contrive, devise") and ingenium ("cleverness").
The work of engineers forms the link between scientific discoveries and their subsequent applications to human needs and quality of life.
In 1960, the Conference of Engineering Societies of Western Europe and the United States of America defined "professional engineer" as follows:
Engineers develop new technological solutions. During the engineering design process, the responsibilities of the engineer may include defining problems, conducting and narrowing research, analyzing criteria, finding and analyzing solutions, and making decisions. Much of an engineer's time is spent on researching, locating, applying, and transferring information. Indeed, research suggests engineers spend 56% of their time engaged in various information behaviours, including 14% actively searching for information.
In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.
Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.
Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.
At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO2); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.
A documentary film is a nonfictional motion picture intended to document some aspect of reality, primarily for the purposes of instruction or maintaining a historical record. Such films were originally shot on film stock—the only medium available—but now include video and digital productions that can be either direct-to-video, made into a TV show or released for screening in cinemas. "Documentary" has been described as a "filmmaking practice, a cinematic tradition, and mode of audience reception" that is continually evolving and is without clear boundaries.
In popular myth, the word documentary was coined by Scottish documentarian John Grierson in his review of Robert Flaherty's film Moana (1926), published in the New York Sun on 8 February 1926, written by "The Moviegoer" (a pen name for Grierson).
Grierson's principles of documentary were that cinema's potential for observing life could be exploited in a new art form; that the "original" actor and "original" scene are better guides than their fiction counterparts to interpreting the modern world; and that materials "thus taken from the raw" can be more real than the acted article. In this regard, Grierson's definition of documentary as "creative treatment of actuality" has gained some acceptance, with this position at variance with Soviet film-maker Dziga Vertov's provocation to present "life as it is" (that is, life filmed surreptitiously) and "life caught unawares" (life provoked or surprised by the camera).

Marine hydrokinetic energy engineers at APL-UW invented a free-drifting power station. The Wave Energy Buoy that Self deploys (WEBS) converts surface wave energy to mechanical and electrical power. “As opposed to typical wave energy devices that are anchored to the sea floor and cabled to shore, WEBS is all about having an easily deployed power station anywhere in the off-shore environment.” —Andy Stewart, APL-UW Principal Engineer Potential applications include power sensor payloads for scientific instrumentation; power station for autonomous systems, undersea vehicles, and/or surface vessels; and communications relay. This research and development project is a collaboration among APL-UW, the Monterey Bay Aquarium Research Institute, and Columbia Power Technologies.
Paul Woskov, a senior research engineer at MIT’s Plasma Science and Fusion Center (PSFC), is using a gyrotron, a specialized radio-frequency (RF) wave generator developed for fusion research, to explore how millimeter RF waves can open holes through hard rock by melting or vaporizing it. Penetrating deep into hard rock is necessary to access virtually limitless geothermal energy resources, to mine precious metals or explore new options for nuclear waste storage. The film clips show a granite sample being hit with a 28 GHz gyrotron beam of about 2 kW coming in from the top. In the first clip the beam is turned on and you see the rock glow start and increase in intensity. There are yellow flame-like flashes of plasma breakdown. In the second clip, the airflow down the waveguide with the bea...

Rakesh Agrawal, Winthrop E. Stone Distinguished Professor of Chemical Engineering at Purdue University, presents "Energy Solutions for a Fossil Fuel-Deprived Future" on February 9, 2009. Abstract: Recent swings in oil prices remind us that the world's supply of fossil fuels is finite. Roughly 85 percent of current energy use is being met by fossil fuels and the rapid increase in energy demand by developing nations is leading to ever-increasing use of coal, oil and natural gas. Therefore, alternate primary energy sources are being identified and developed to permit the continued functioning of the future world economy. In this presentation, Agrawal describes the current landscape of alternative sustainable primary energy sources: solar, wind, nuclear, and biomass. Agrawal also revie...

Thorium is an abundant material currently disposed of as waste. It is found in coal ash piles and mine tailings. A single Rare Earths mine could produce enough Thorium byproduct to power the entire planet. To do so requires a very different nuclear reactor than the kinds we use today. Not one that uses solid fuel rods, but a reactor in which the fuel is kept in a liquid state. Not one that uses pressurized water as a coolant, but a reactor that uses extremely stable molten salts. The full description of this reactor is: 2-Fluid, Thermal-Spectrum, Molten-Salt Breeder Reactor equipped with a chemical fuel salt treatment module. Such a reactor was conceived of decades ago, as documented in the book "Fluid Fuel Reactors" [1958]. Or, simply "LFTR" (Liquid Fluoride Thorium Reactor) as propose...
Engineer Afsaneh Cooper describes her academic and training life as a Mechanical CAD Engineer & tutor in this video. She is expert in Flywheel Energy Storage System and she started this research in a PhD course when there was a small grant to design and build her flywheel. She could not find a second expert in Australia as a PhD supervisor to graduate from this course which took 23 years and still she is the only who is expert in this field in Australia but can not enroll in any Australian University to graduate due to lack of capacity of Australian Universities for her supervision and resources in Flywheel Energy Storage System! So she can not go to work in the field she spent most of her life to research and study!

In 2003 Paul Burley encountered a prehistoric Native American medicine wheel at an elevation of over 10,500 ft in the mountains of Wyoming. A professional engineer and environmental geologist with over 25 years experience investigating the history of human impacts on the natural environment, Paul has researched sacred symbolism expressed by prehistoric and historic cultural traditions around the world. His research led to discovering that the medicine wheel in Wyoming was, and remains, an integral part of the largest stone circle on earth -- 550 miles in diameter. His further research led to the startling finding that all sacred circular structures --ranging from design of the original ark of the Great Flood described in the Sumerian Epic of Gilgamesh to mandalas of eastern philosophy, fro...
