A pendulum wave is an elementary physics demonstration and kinetic art comprising a number of uncoupled simple pendulums with monotonically increasing lengths. As the pendulums oscillate, they appear to produce travelling and standing waves, beating, and random motion. [1] [2] [3]
Demonstration First self-sustaining nuclear chain reaction: 1945 Trinity: Manhattan Project: Demonstration First nuclear weapon detonation 1947 Lamb–Retherford experiment: Willis Lamb and Robert Retherford: Discovery Lamb shift/Vacuum energy: 1956 Wu experiment: Chien-Shiung Wu: Confirmation Parity violation 1956 Cowan–Reines neutrino ...
Hand boiler — demonstrates vapour-liquid equilibrium and simple heat engine principles; Newton's cradle — demonstrates elastic collision, conservation of momentum, and conservation of energy; Gauss gun; Plate trick or Dirac belt trick — demonstrates spinors and the double cover of SO(3) by SU(2)
Most scientific demonstrations are simple laboratory demonstrations intended to demonstrate physical principles, often in a surprising or entertaining way. They are carried out in schools and universities, and sometimes in public demonstrations in popular science lectures and TV programs aimed at the public.
Demonstrations in Physics was an educational science series produced in Australia by ABC Television in 1969 [citation needed]. The series was hosted by American scientist Julius Sumner Miller , who demonstrated experiments involving various disciplines in the world of physics .
The balloon rocket can be used easily to demonstrate simple physics, namely Newton’s third law of motion. [2] A common experiment with a balloon rocket consists in adding other objects such as a string or fishing line, a drinking straw and adhesive tape to the balloon itself. The string is threaded through the straw and is attached at both ...
The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane of oscillation appears to change ...
Faraday's ice pail experiment is a simple electrostatics experiment performed in 1843 by British scientist Michael Faraday [1] [2] that demonstrates the effect of electrostatic induction on a conducting container. For a container, Faraday used a metal pail made to hold ice, which gave the experiment its name. [3]
