## Special Relativity

**Special relativity** (**SR**, also known as the **special theory of relativity** or **STR**) is the physical theory of measurement in an inertial frame of reference proposed in 1905 by Albert Einstein in the paper "On the Electrodynamics of Moving Bodies".

### Famous quotes containing the words relativity and/or special:

“By an application of the theory of *relativity* to the taste of readers, to-day in Germany I am called a German man of science, and in England I am represented as a Swiss Jew. If I come to be regarded as a bête noire the descriptions will be reversed, and I shall become a Swiss Jew for the Germans and a German man of science for the English!”

—Albert Einstein (1879–1955)

“An indirect quotation we can usually expect to rate only as better or worse, more or less faithful, and we cannot even hope for a strict standard of more and less; what is involved is evaluation, relative to *special* purposes, of an essentially dramatic act.”

—Willard Van Orman Quine (b. 1908)
