Relativistic kinetic energy increases to infinity when approaching the speed of light, thus no massive body can reach this speed. Tests of relativistic energy and momentum are aimed at measuring the relativistic expressions for energy, momentum, and mass. According to special relativity, the properties of particles moving approximately at the ...
Peter T. Demos (July 18, 1918 – September 18, 2012) was a professor in the Department of Physics and the Laboratory for Nuclear Science at MIT. [1] A native of Peterborough, Ontario, Demos attended Peterborough Collegiate and Vocational School and Queen's University, and received a Ph.D. in Physics from MIT in 1951. [2]
Alma mater. Boston University. Known for. Children's television. Scientific career. Fields. Physics education. Julius Sumner Miller (May 17, 1909 – April 14, 1987) was an American physicist and television personality. [1] He is best known for his work on children's television programs in North America and Australia.
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
In physics, the monkey and hunter is a hypothetical scenario often used to illustrate the effect of gravity on projectile motion. [1] It can be presented as exercise problem or as a demonstration. The essentials of the problem are stated in many introductory guides to physics. [2] [3] In essence, the problem is as follows:
Wigner's friend is a thought experiment in theoretical quantum physics, first published by the Hungarian-American physicist Eugene Wigner in 1961, [1] and further developed by David Deutsch in 1985. [2] The scenario involves an indirect observation of a quantum measurement: An observer observes another observer who performs a quantum ...

Below: In S′ the distance between the spaceships increases, while the string length stays the same. Bell's spaceship paradox is a thought experiment in special relativity. It was first described by E. Dewan and M. Beran in 1959 [1] but became more widely known after John Stewart Bell elaborated the idea further in 1976. [2]
