Four Lectures on Relativity and Space

1923. In this excellent exposition, Charles Steinmetz, one of America's great electrical geniuses, successfully translated the complex mathematical reasoning at the heart of the theory into language that even the layman can follow. Using analogies, examples, and comparisons as substitutes for intricate formulas and experiments, he has produced a carefully written, scientifically accurate statement of the Einstein's theory of relativity and its fascinating conclusions and deductions which involves only elementary mathematics.
