44Anti-Judaism — has been called a total or partial opposition to Judaism mdash;and to Jews as adherents of it mdash;by persons who accept a competing system of beliefs and practices and consider certain genuine Judaic beliefs and practices as inferior. [Langmuir …
45Pauli exclusion principle — The Pauli exclusion principle is a quantum mechanical principle formulated by Wolfgang Pauli in 1925. It states that no two identical fermions may occupy the same quantum state simultaneously . A more rigorous statement of this principle is that …
46Cloud seeding — can be done by ground generators, plane, or rocket (not shown). Cloud seeding, a form of intentional weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air… …
47mass spectrometry — or mass spectroscopy Analytic technique by which chemical substances are identified by sorting gaseous ions by mass using electric and magnetic fields. A mass spectrometer uses electrical means to detect the sorted ions, while a mass spectrograph …
48Plasma oscillation — Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals. The frequency only depends weakly on the wavelength. The quasiparticle… …
49Ice-nine — is a fictional material conceived by writer Kurt Vonnegut in his novel Cat s Cradle . It is supposed to be a more stable polymorph of water than common ice (Ice Ih) which instead of melting at 0° Celsius (32° Fahrenheit), melts at 45.8°C… …
50electron tube — an electronic device that consists, typically, of a sealed glass bulb containing two or more electrodes: used to generate, amplify, and rectify electric oscillations and alternating currents. Also called electronic tube. Cf. gas tube, vacuum tube …
