1st says that diffusive flux goes high to low concentrations proportional to concentration gradient/2nd predicts how diffusion causes the concentration to change with time

In solid-state physics this is the minimum thermodynamic work (i.e. energy) needed to remove an electron from a solid to a point in the vacuum immediately outside the solid surface

Differential equations arising from Newton's 2nd law that describe the motion of fluid substances/3-D version is a Millenium problem

Formula from atomic physics that describes wavelengths of spectral lines of many chemical elements

Partial differential equation involving the Laplacian, wavenumber, & amplitude that can be used to analyze vibrating membranes, 3-D solutions, & paraxial approximations

2nd-order partial differential equation/solutions are the harmonic functions/used in Potential Theory & physics app to describe potentials

Calculates reduction potential of a half-cell or total voltage of full cell (electrochemical cells) at non-standard rates

Organic chemical reaction between a conjugated diene and a substituted alkene (dienophile) to form a cyclohexene system

Partial differential eq in nonrelativistic quantum mechanics that describes how quantum state of a physical system changes with time

Symbolized by Greek psi/solution function of Schrodinger equation/describes quantum state of particle or system in isolation

Thought experiment relating to quantum mechanics where a cat, poison, & radioactive source are in sealed box/cat is simultaneously alive & dead

Thought experiment to show 2nd Law of Thermo has only 'statistical certainty'/container of gas at equilibrium is divided with door opened by namesake creature/decreases entropy

Expulsion of a magnetic field from a superconductor during its transition to the superconducting state

Vector resulting from the cross product of the electric & magnetic field vectors

Boundary which determines whether a star that goes supernova will turn into a neutron star or black hole

Maximum mass of a stable white dwarf star/named for 19 year-old Indian-American astrophysicist/above this mass would undergo gravitational collapse into neutron star or black hole

Mass of substance altered at electrode is directly proportional to charge transfered there/for DC charge, mass of altered material at electrode is dir prop to elements equiv weight

Relates the attenuation of light to the properties of the material through which the light is traveling

Gives statistical behavior of thermodynamic system not in thermo equil/fluid w/temp gradients in space cause heat to flow from hotter to colder regions by random transport
