Foundations is a series of articles, first published in the magazine
Eidolon, on some of the theories of twentieth-century physics that
have most influenced modern science fiction. However, these are not
essays on the history or philosophy of science; their aim is to show
how the central idea of each theory leads to detailed, quantitative
predictions of real physical effects. For example, the article on
special relativity derives formulas for time dilation, Doppler shift,
and aberration.

These articles are for the interested lay reader. No prior knowledge
of mathematics beyond high school algebra and geometry is needed.
