| Keywords/Importance | Term/Person |
|---|---|
| Total wave function for two identical fermions is anti-symmetric with respect to exchange of the particles. No two fermions (half-integer-spin particles) may occupy same quantum state. Bosons unaffected. | Pauli Exclusion Principle |
| Idea of stimulated emission, proved Planck's radiation equation. Developed equivalence principle. "On the Electrodynamics of Moving Bodies." 1921 Nobel in Physics for photoelectric effect. Special relativity. | Albert Einstein |
| Violates CPT symmetry. Carlo Rubbia and Simon Van der Meer won 1984 Nobel for helping discover particles that carry this force. W and Z Bosons. Responsible for beta decay. Unified w/ electromagnetic force. | Weak nuclear force |
| Particle. 0 spin, negative parity. decay result in tau and Theta particles, leading to CP violation.most famous discovered by Richter and ting, called charmonium. Made of quark-antiquark pair. | Meson |
| Differential travel times of PKP used to explain super-rotation of this region. Separated into inner solid and outer liquid region. Rotation gives rise to earth's magnetic field. Compressed nickel and iron. | Earth's core |
| Process. Occurs when quantity equal to product of Grashof and Prantl number is above 1700. Primary mode of heat transfer in fluids. | Convection |
| Associated with principle of superposition. Occurs when two waves in a medium interact. Constructive or destructive. | Interference |
| experiment. performed by 2 American scientists. Used interference pattern generated by light waves reflected by mirrors to disprove existence of luminiferous ether. | Michelson-Morley Experiment |
| Principle. Named for Dutch scientist. States that every point on wave front is a source of secondary waves. | Huygens Principle |
| Subtracting magnetic pressure from this quantity gives Lorentz force. Laplace's Law: Pressure=twice this over radius. In free-body diagrams, must be vector pointing away from object. Cannot push, only pull. "Surface" variety. | Tension |
| Phenomenon. First observed by Lunik II satellite. Discontinuity caused by interaction with planetary magnetic field called bow shock. Stream of particles ejected by sun's corona. | Solar wind |
| Force. Particle undergoing circular motion. Always points inwards | Centripetal force |
| Force. Exerted perpendicular to surface. Used to represent force exerted by ground counteracting gravity. | Normal force |
| Force. Acts between surfaces in motion relative to each other. Proportional to normal force. | Kinetic friction |
| Ration of atomic number to atomic volume, divided by ratio as extrapolated from noble gas data. Tendency of an atom to attract electrons to itself. | Electronegativity |
| Lorentz equation describes force exerted on a mobile one. Denoted as Z. Millikan's oil drop experiment measured this. | Charge |
| Thomas Savery built a machine implementing this principle. Also discovered by Edme Mariotte. Related to Gay-Lussac and Charles' Laws. Pressure and volume of a gas in a closed system are inversely proportional. | Boyle's Law |
| Has SI units of kilogram meter squared per second cubed per ampere square. Omega, named for a German. | Ohm |
| Ohm is unit of this quantity. Increases with increasing length and temperature. | Resistance |
| Cornu spiral used to approximate this effect. When Fresnel number is much less than 1, a form predominated named for Fraunhofer. Light bending around obstacles. | Diffraction |
