DeLorean Time Machine
In the ''Back to the Future'' franchise, the DeLorean time machine is a time travel device made by retrofitting a DMC DeLorean vehicle with a flux capacitor. The car requires 1.21 gigawatts ("jigawatts/jigowatts") of power and needs to travel 88 miles per hour (142 km/h) to initiate time travel. Operation The control of the time machine is the same in all three films. The operator is seated inside the DeLorean (except the first time, when the remote control is used), and turns on the time circuits by turning a handle near the gear lever, activating a unit containing multiple fourteen- and seven-segment displays that show the destination (red), present (green), and last departed (yellow) dates and times. After entering a target date with the keypad inside the DeLorean, the operator accelerates the car to 88mph (142km/h), which activates the flux capacitor. As it accelerates, several coils around the body glow blue/white while a burst of light appears in front of it. Surrou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Back To The Future (franchise)
''Back to the Future'' is an American science fiction comedy franchise created by Robert Zemeckis and Bob Gale. The franchise follows the adventures of a high school student, Marty McFly, and an eccentric scientist, Dr. Emmett "Doc" Brown, as they use a DeLorean time machine to time travel to different periods in the history of the fictional town of Hill Valley, California. The first ''Back to the Future'' film was the highest-grossing film of 1985 and became an international phenomenon, leading to the second and third films, which were back-to-back film productions, released in 1989 and 1990, respectively. Though the sequels did not perform quite as well at the box office as the first film, the trilogy remains immensely popular and has yielded such spin-offs as an animated television series and a motion-simulation ride at the Universal Studios Theme Parks in Universal City, California; Orlando, Florida; and Osaka, Japan (all now closed), as well as a video game and a stag ...

Back To The Future Part III
''Back to the Future Part III'' is a 1990 American science fiction Western film and the final installment of the ''Back to the Future'' trilogy. The film was directed by Robert Zemeckis, and stars Michael J. Fox, Christopher Lloyd, Mary Steenburgen, Thomas F. Wilson, and Lea Thompson. The film continues immediately following ''Back to the Future Part II'' (1989); while stranded in 1955 during his time travel adventures, Marty McFly (Fox) discovers that his friend Dr. Emmett "Doc" Brown (Lloyd), trapped in 1885, was killed by Buford "Mad Dog" Tannen (Wilson), Biff's great-grandfather. Marty travels to 1885 to rescue Doc and return once again to 1985, but matters are complicated when Doc falls in love with Clara Clayton (Steenburgen). ''Back to the Future Part III'' was filmed in California and Arizona, and was produced on a $40 million budget back-to-back with ''Part II''. ''Part III'' was released in the United States on May 25, 1990, six months after the previous ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Circuits2
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. 108 pages. Time in physics is operationally defined as "what a clock reads". The physical nature of time is addressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space-time
In physics, spacetime is a mathematical model that combines the three-dimensional space, three dimensions of space and one dimension of time into a single four-dimensional manifold. Minkowski diagram, Spacetime diagrams can be used to visualize Special relativity, relativistic effects, such as why different observers perceive differently where and when events occur. Until the 20th century, it was assumed that the three-dimensional geometry of the universe (its spatial expression in terms of coordinates, distances, and directions) was independent of one-dimensional time. The physicist Albert Einstein helped develop the idea of spacetime as part of his theory of relativity. Prior to his pioneering work, scientists had two separate theories to explain physical phenomena: Isaac Newton's laws of physics described the motion of massive objects, while James Clerk Maxwell's electromagnetic models explained the properties of light. However, in 1905, Einstein based wikisource:Translation:On ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminum Metal Toys
Aluminum Model Toys (AMT) is a toy manufacturing brand founded in Troy, Michigan in 1948 by West Gallogly Sr. AMT became known for manufacturing 1/25 scale plastic automobile dealer promotional model cars and friction motor models, and pioneered the annual 3-in-1 model kit buildable in stock, custom, or hot-rod versions. The company made a two-way deal in 1966 with Desilu Productions to produce a line of ''Star Trek'' models and to produce a 3/4 scale exterior and interior filming set of the ''Galileo'' shuttlecraft. It was also known for producing model trucks and movie and TV vehicles. The AMT brand was bought in 1978 by the Lesney company of UK, then by competitor Ertl in 1983, then by the Round 2 company in 2012. Beginning Because Gallogly had solid connections with Ford Motor Company, he was able to place his first models exclusively in Ford dealerships, starting a long promotional relationship. Gallogly's first model was a 1947–1948 Ford Fordor sedan made of cast alumin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Power
Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively. A common misconception is that electric power is bought and sold, but actually electrical energy is bought and sold. For example, electricity is sold to consumers in kilowatt-hours (kilowatts multiplied by hours), because energy is power multiplied by time. Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes (as domestic mains electricity) by the electric power industry through an electrical grid. Electric power can be delivered over long distances by transmission lines and used for applications such as motion, light or heat with high efficiency. ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geissler Tube
A Geissler tube is an early gas discharge tube used to demonstrate the principles of electrical glow discharge, similar to modern neon lighting. The tube was invented by the German physicist and glassblower Heinrich Geissler in 1857. It consists of a sealed, partially evacuated glass cylinder of various shapes with a metal electrode at each end, containing rarefied gasses such as neon, argon, or air; mercury vapor or other conductive fluids; or ionizable minerals or metals, such as sodium. When a high voltage is applied between the electrodes, an electrical current flows through the tube. The current dissociates electrons from the gas molecules, creating ions, and when the electrons recombine with the ions, the gas emits light by fluorescence. The color of light emitted is characteristic of the material within the tube, and many different colors and lighting effects can be achieved. The first gas-discharge lamps, Geissler tubes were novelty items, made in many artistic shapes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flux Capacitor Replica Kovacs
Flux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance. Flux is a concept in applied mathematics and vector calculus which has many applications to physics. For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface. Terminology The word ''flux'' comes from Latin: ''fluxus'' means "flow", and ''fluere'' is "to flow". As ''fluxion'', this term was introduced into differential calculus by Isaac Newton. The concept of heat flux was a key contribution of Joseph Fourier, in the analysis of heat transfer phenomena. His seminal treatise ''Théorie analytique de la chaleur'' (''The Analytical Theory of Heat''), defines ''fluxion'' as a central quantity and proceeds to derive the now well-known expressio ...

SI Prefix
The International System of Units, known by the international abbreviation SI in all languages and sometimes pleonastically as the SI system, is the modern form of the metric system and the world's most widely used system of measurement. Established and maintained by the General Conference on Weights and Measures (CGPM), it is the only system of measurement with an official status in nearly every country in the world, employed in science, technology, industry, and everyday commerce. The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity). The system can accommodate coherent units for an unlimited number of additional quantities. These are called coherent derived units, which can always be represented as pr ...

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...
