Recently, the fields of number theory and prime numbers have had enormous impact on disciplines such as computing, communications, and physics. However, many of the theorems related to prime numbers remain the exclusive domain of mathematicians. This book is designed to educate non-mathematicians on the connections between the Riemann zeta-function and the distribution of prime numbers. The subject matter is presented without the use of rigorous mathematical language, and complicated ideas are illustrated through simple examples. It is appropriate for physicists, electrical engineers, computer scientists, and students in these fields.
