Sidelights on Relativity

An exceptional historic document composed of two distinct addresses by Albert Einstein. Firstly, recounting the stumbling of Physical Science from Newton's theory to his own: the intrinsic relation of matter and energy; and how the influence of problems derived from Hertz's investigations in electro-......more

If you want to know anything about the basics of relativity, Einstein's pretty much the only one to read. He brings an unusual and remarkable clarity to his own work without grandstanding. This short bit combines two lectures from the early 1920s answering some of the inherent queries on his recent w......more

Short but very interesting and surprisingly clear! It really brings out Einstein's ability to explain difficult concepts in a way which pretty much confirms one of his quotes: "If you can't explain it to a six year old, you don't understand it yourself." (At least I think he really said it, you can ne......more

Comprised of two lectures delivered at the University of Leyden (1920) and the Prussian Academy of Sciences (1921), Sidelights on Relativity is probably best served to gluttons. (I count myself among them.) "Ether and Relativity" is his rebuttal of the idea of a universal "ether" through which t......more

This book is for anyone. This gives a nice context to Relativity, without actually explaining much about it, but by through two relevant stories (one about the theory of light and the other about the transition to non-euclidean geometries), Einstein, the man himself, gives an accessible potted scien......more
