The Last Podcast on the Left is a weekly podcast on the Last Podcast Network [ 1 ] featuring podcast producer and researcher Marcus Parks, comedian and actor Henry Zebrowski, and comedian Ed Larson, three longtime friends. Episodes have explored the topics of serial killers, cults, conspiracy theories, UFO sightings, ghosts, cryptids, the ...
The 1984 United States presidential election was the 50th quadrennial presidential election, held on Tuesday, November 6, 1984.Incumbent Republican President Ronald Reagan and his running mate, incumbent Vice President George H. W. Bush, were re-elected to a second term in a landslide.
Radiation exposure. Radiation exposure is a measure of the ionization of air due to ionizing radiation from photons. [1] It is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. [1] As of 2007, "medical radiation exposure" was defined by the International Commission on ...
In physics, charge conservation is the principle that the total electric charge in an isolated system never changes. [1] The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved. Charge conservation, considered as a physical conservation law, implies that the ...
Free neutron decay. radiation, the emission of a fast electron from the nucleus (the accompanying antineutrino is omitted). In the Rutherford model for the nucleus, red spheres were protons with positive charge and blue spheres were protons tightly bound to an electron with no net charge . : The inset shows beta decay of a free neutron as it is ...
Electron-beam lithography (often abbreviated as e-beam lithography or EBL) is the practice of scanning a focused beam of electrons to draw custom shapes on a surface covered with an electron-sensitive film called a resist (exposing). [1] The electron beam changes the solubility of the resist, enabling selective removal of either the exposed or ...
A surface charge is an electric charge present on a two-dimensional surface. These electric charges are constrained on this 2-D surface, and surface charge density, measured in coulombs per square meter (C•m −2 ), is used to describe the charge distribution on the surface. The electric potential is continuous across a surface charge and the ...
The nautical mile (nmi) was originally defined as the arc length of a minute of latitude on a spherical Earth, so the actual Earth circumference is very near 21 600 nmi. A minute of arc is π 10 800 of a radian . A second of arc, arcsecond (arcsec), or arc second, denoted by the symbol ″, [2] is 1 60 of an arcminute, 1 3600 ...
