Reader’s review:
The Pythagorean Theorem has been with us for over 4000 years and has never ceased to yield its bounty to mathematicians, scientists, and engineers. Amateurs love it in that most new proofs are discovered by amateurs. Without the Pythagorean Theorem, none of the following is possible: radio, cell phone, television, internet, flight, pistons, cyclic motion of all sorts, surveying and associated infrastructure development, and interstellar measurement.
