Maxwell's equations - Wikipedia
WEB3 days ago · The covariant formulation (on spacetime rather than space and time separately) makes the compatibility of Maxwell's equations with special relativity manifest. Maxwell's equations in curved spacetime, commonly used in high-energy and gravitational physics, are compatible with general relativity.
The Gravity of Math: How Geometry Rules the Universe
WEB6 days ago · And in his monumental March 1916 paper, “Foundation of the General Theory of Relativity,” he considered how the Sun’s gravitational field would affect, as well as deflect, light from a ...
Hubble's law - Wikipedia
WEB3 days ago · In this form H0 = 7%/Gyr, meaning that at the current rate of expansion it takes a billion years for an unbound structure to grow by 7%. Although widely attributed to Edwin Hubble, [6] [7] [8] the notion of the universe expanding at a calculable rate was first derived from general relativity equations in 1922 by Alexander Friedmann.
Schrödinger equation - Wikipedia
WEB5 days ago · A more general form of the Schrödinger equation that also applies in relativistic situations can be formulated within quantum field theory (QFT), a framework that allows the combination of quantum mechanics with special relativity.

WEB4 days ago · gravity, in mechanics, the universal force of attraction acting between all matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. On the other hand, through its long reach and universal action, it controls the trajectories of bodies in the solar system and ...
Special Relativity | Brilliant Math & Science Wiki
WEB5 days ago · It is customary in special relativity to name this ratio \gamma γ (the Greek letter gamma) and rewrite the expression in the form. \gamma = \frac {c} {\sqrt {c^2 - v^2}} = \frac {1} {\sqrt {1 - \frac {v^2} {c^2}}}, γ = c2 −v2c = 1− c2v21, in which case one may write simply. \frac {t} {t'} = \gamma. t′t = γ.

Mathematicians Attempt to Glimpse Past the Big Bang
WEB5 days ago · The strategy is to apply Einstein’s general theory of relativity — a theory that equates gravity with the curvature of space-time — as far back into time as it can go. That’s the hope of three researchers: Ghazal Geshnizjani of the Perimeter Institute, Eric Ling of the University of Copenhagen, and Jerome Quintin of the University of ...
