This little book concentrates on the foundations of modern physics (its "ABC`s") and its most fundamental constants: c the velocity of light and ? the quantum of action.
First of all, the book is addressed to professional physicists, but in order to achieve maximal concentration and clarity it uses the simplest (high school) mathematics. As a result many pages of the book will be useful to college students and may appeal to a more general audience.
Readership: College students and interested readers in the physical sciences.
