In physics, the term sometimes refers collectively to electromagnetic radiation of any wavelength, in which case light includes gamma rays, X-rays, microwaves, and radio waves, but in common usage "light" more often refers specifically to visible light. linear actuator A form of motor that generates a linear movement directly. linear algebra
A Magic Triangle image mnemonic - when the terms of Ohm's law are arranged in this configuration, covering the unknown gives the formula in terms of the remaining parameters. It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ.
Meaning SI unit of measure alpha: alpha particle: angular acceleration: radian per second squared (rad/s 2) fine-structure constant: unitless beta: velocity in terms of the speed of light c: unitless beta particle: gamma: Lorentz factor: unitless photon: gamma ray: shear strain: radian

An astronomy enthusiast while still a child, he studied at the Tokyo College of Physics and at the Institute of Cosmical Physics in Kyoto. While participating in Kyoto University's expedition to the total solar eclipse on 1941 Sept. 21 he obtained color photographs of the solar corona, the first in Japan.
Leibniz accepted the principle of conservation of momentum, but rejected the Cartesian version of it. [2] The difference between these ideas was whether the quantity of motion was simply related to a body's resistance to a change in velocity (vis inertia) or whether a body's amount of force due to its motion (vis viva) was related to the square ...
Edward Witten (born August 26, 1951) is an American theoretical physicist known for his contributions to string theory, topological quantum field theory, and various areas of mathematics.
Besso was born in Riesbach from a family of Italian Jewish descent. [2] He was a close friend of Albert Einstein during his years at the Federal Polytechnic Institute in Zurich, [3] (today known as ETH Zurich) and then at the patent office in Bern, where he helped Einstein to get a job. [4]
