  2. Mass–energy equivalence - Wikipedia

    en.wikipedia.org/wiki/Mass–energy_equivalence

    In analyzing these extreme events, Einstein's formula can be used with E as the energy released (removed), and m as the change in mass. In relativity, all the energy that moves with an object (i.e., the energy as measured in the object's rest frame) contributes to the total mass of the body, which measures how much it resists acceleration.

  3. Einstein field equations - Wikipedia

    en.wikipedia.org/wiki/Einstein_field_equations

    The study of exact solutions of Einstein's field equations is one of the activities of cosmology. It leads to the prediction of black holes and to different models of evolution of the universe. One can also discover new solutions of the Einstein field equations via the method of orthonormal frames as pioneered by Ellis and MacCallum. [22]

  4. Outline of Albert Einstein - Wikipedia

    en.wikipedia.org/wiki/Outline_of_Albert_Einstein

    [3] [4] Einstein is best known by the general public for his mass–energy equivalence formula E = mc 2 (which has been dubbed "the world's most famous equation"). [5] He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect ", a pivotal step in ...

  5. Timeline of special relativity and the speed of light - Wikipedia

    Enterprise crew members are spelling out Einstein's mass–energy equivalence formula E = mc 2 on the flight deck. Theories other than SR are not described here exhaustively, but only to the extent that is directly relevant to SR – i.e. at points when they: anticipated some elements of SR, like Fresnel’s hypothesis of partial aether drag,

    en.wikipedia.org/wiki/General_relativity

    General relativity, also known as the general theory of relativity, and as Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.

  7. Why Does E=mc²? - Wikipedia

    en.wikipedia.org/wiki/Why_Does_E=mc²?

    Why Does E=mc²? (And Why Should We Care?) is a 2009 book by the theoretical physicists Brian Cox and Jeff Forshaw . [ 1 ] This was the first full-scale book from Professors Cox and Forshaw.

  8. Postulates of special relativity - Wikipedia

    en.wikipedia.org/wiki/Postulates_of_special...

    1. First postulate (principle of relativity) The laws of physics take the same form in all inertial frames of reference.. 2. Second postulate (invariance of c) . As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body.

  9. Einstein solid - Wikipedia

    en.wikipedia.org/wiki/Einstein_solid

    The Einstein solid is a model of a crystalline solid that contains a large number of independent three-dimensional quantum harmonic oscillators of the same frequency. The independence assumption is relaxed in the Debye model .
