The apostrophe replaces the i in the word it to create ’tis . . . not quite how we create contractions today. According to Google’s Ngram Viewer, the contraction ’tis was a fan favorite in the early 1700s. At this time, it was likely used more often than it’s. Why is ’tis used? ‘Tis …

British Dictionary definitions for lorentz-fitzgerald contraction
the supposed contraction of a body in the direction of its motion through the ether, postulated to explain the result of the Michelson-Morley experiment. The special theory of relativity denies that any such real change can occur in a body as a result of uniform motion but shows that an observer moving with respect to the body will determine an apparent change given by a formula similar to that of Lorentz and Fitzgerald

Science definitions for lorentz-fitzgerald contraction
[ lôr′ənts-fĭts-jĕr′ld ]
The shortening of an object along its direction of motion as its speed approaches the speed of light, as measured by an observer at rest with respect to the body. Lorentz-FitzGerald contraction is an effect predicted by Einstein's theory of Special Relativity. It is named for Dutch physicist Hendrik Lorentz and Irish physicist George Francis FitzGerald (1851-1901), who independently proposed such a contraction. See more at relativity.
