(physics) The generic term of the special relativity and the general relativity, two theories in physics developed mainly by Albert Einstein at the beginning of the 20th century from which several important results such as the equivalence of matter and energy and the Einstein field equations are derived.
But if you remember Einstein... he knew the theory of relativity to be true... long before he could prove it.
Mutta jos muistatte Einsteinin - hän tiesi, että suhteellisuusteoria oli totta - paljon ennen kuin hän pystyi todistamaan sen.OpenSubtitles2018.v3 OpenSubtitles2018.v3
