In its frequent incarnation as a physics demonstration, a Gauss gun usually consists of series of ferromagnetic balls on a nonmagnetic track. On the track is a permanent magnet with a ball, the projectile, stuck to the front of it. Between the projectile and the magnet is a spacer, usually consisting of one or more additional balls.
For the first time measurements of their spectral characteristics were determined. Collaborative works directed by V.F. Minin were started to develop high-quality non-aberrational quasi-optical lens of submillimeter-wave range on the basis of theoretical insights and the unique equipment of the Institute of Applied Physics.
Newton's cradle is a device, usually made of metal, that demonstrates the principles of conservation of momentum and conservation of energy in physics with swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, compressing them and thereby transmitting a pressure wave through the stationary ...
Early high-speed visualisations of electrical voltages were made with an electro-mechanical oscillograph, [2] [3] invented by André Blondel in 1893. These gave valuable insights into high speed voltage changes, but had a frequency response in single kHz, and were superseded by the oscilloscope which used a cathode-ray tube (CRT) as its display element.
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
His first teaching position was with the University of Pittsburgh at Johnstown. In the early 1980s, he performed his first physics show at the university's open house. A few months later, Willey made a 15-minute video of physics demonstrations with a group of troubled boys from a remand home.
The Laboratory for Elementary-Particle Physics (LEPP) is a high-energy physics laboratory studying fundamental particles and their interactions. The 768-meter Cornell Electron Storage Ring (CESR) is in operation below the campus athletic fields. CESR is an electron-positron collider operating at a center-of-mass energy in the range of 3.5–12 GeV.
