How do you pronounce relativity?
you pronounce it as 'relativity'
When speaking of Relativity, people mostly think of Albert Einstein. However, Relativity was experimented by Galileo Galilei first. So when speaking of Relativity, it helps to be specific: Einsteinian Relativity or Galilean Relativity. Please visit http://physics.ucr.edu/~wudka/Physics7/Notes_www/node47.html for more information about Galilean Relativity.
The theorizer of relativity would be Albert Einstein. Einstein's theory of relativity consisted of special relativity and general relativity. It has to do with relative measurements of quantities to observes, like space contracts and time dilates. Space time was a concept of relativity. The speed of lights invariance was also a part of the theory.
Relativity has two parts: General relativity and special relativity, general relativity describes gravity as a geometric property of spacetime and special relativity is the physical theory of measurement in inertial frames of reference. Now quantum mechanics, in it's wave formulation, deals with describing things on the atomic scale as a wavefunction.
Original theory of relativity: Galileo Galilei The theories of general and special relativity: Albert Einstein Albert Einstein developed the theory of relativity. Albert Einstein developed the theory of relativity between 1907 through 1915. It was further developed by Max Planck, Hermann Minkowski, and others. If you are referring to the theory of relativity it would be Albert Einstein Albert Einstein
Relativity was a concept in physics before Einstein came along. Galileo wrote about "The Basic Principle of Relativity". So "Special Relativity" refers to relativity applied to the special case of light beams (and spacetime)--the study of which Galileo was not equipped to tackle, since in his time the speed of light had not even been determined (although later it became clear that there had been some data laying around). Einstein's General Theory of Relativity attempted…
