Einstein's theory of general relativity, published in 1916, built upon his earlier work, including special relativity and the mass-energy equivalence, both published in his "Annus Mirabilis" in 1905.

I. IN continuation of my article in the Relativity Number of NATURE (vol. cvi., p. 795, Feb ruary 17, 1921), I propose to discuss more fully, and to express as clearly and simply as possible, some of ...

When the theory of relativity appeared in the early 1900s, it upended centuries of science and gave physicists a new understanding of space and time. Isaac Newton saw space and time as fixed, but in ...
