hi, guys
here, i'm going to introdused all the theories of the great scientist "ALBERT EINSTEIN"
1)Theory of relativity and E = mc²
2)Photons and energy quanta
3)Quantized atomic vibrations
4)Adiabatic principle and action-angle variables
Throughout the 1910s, quantum mechanics expanded in scope to cover many different systems. After Ernest Rutherford discovered the nucleus and proposed that electrons orbit like planets, Niels Bohr was able to show that the same quantum mechanical postulates introduced by Planck and developed by Einstein would explain the discrete motion of electrons in atoms, and the periodic table of the elements.
Einstein contributed to these developments by linking them with the 1898 arguments Wilhelm Wien had made. Wien had shown that the hypothesis of adiabatic invariance of a thermal equilibrium state allows all the blackbody curves at different temperature to be derived from one another by a simple shifting process. Einstein noted in 1911 that the same adiabatic principle shows that the quantity which is quantized in any mechanical motion must be an adiabatic invariant. Arnold Sommerfeld identified this adiabatic invariant as the action variable of classical mechanics.
4)Wave–particle duality
5)Theory of critical opalescence
6)Zero-point energy
7)General relativity and the equivalence principle
8)Gravitational waves
9)Hole argument and Entwurf theory
10)Physical Cosmology
11)Modern quantum theory
12)Bose–Einstein statistics
13)Energy momentum pseudotensor
14)Unified field theory
15)Wormholes
16)Einstein–Cartan theory
17)Equations of motion
18)Other investigations
Main article: Einstein's unsuccessful investigations
Einstein conducted other investigations that were unsuccessful and abandoned. These pertain to force, superconductivity, and other research.

20)Schrödinger gas model
21)Einstein refrigerator
22)Bohr versus Einstein
23)Einstein–Podolsky–Rosen paradox
