1 What the book is about Number theory is known as the queen of math, and prime numbers are her beautiful building blocks, which occurs highly irregularly and yet " predictably " , as spelt out by one of the most famous math breakthroughs, the PNT (Prime Number Theorem), which gives us an asymptotic estimate to the overall distribution of primes over a large interval! With the invention of public key cryptography like RSA and discrete log based cryptosystems, prime numbers are not just interesting in math but in cryptography and the reaal world applications of e-comerce. This book tells us many facts about prime numbers, how to recognise a number is prime efficiently, and how to factorise a number into primes quickly. It covers not just theoretical number theory but the computational aspects which is lacking in most number theory books. One can hardly find a better duo to write such a book: Carl Pomerance and Richard Crandall. Pomerance was the discoverer of the quadratic sieve factoring algorithm, and he has won many awards on expository writing from MAA. Crandall (now deceased) was former chief cryptographer, Distinguished Scientist of Apple, Chief Scientist at NeXT and he had PhD in both math and physics! The book is painstakingly well written (it is enough just to take a look at how they explain the deepest math in computational number theory, which is the fastest factoring algorithm, aka Number Field Sieve) , and along the way interesting authoritative remarks are given at the appropriate places (see for example, page 37, where they stated the equivalence of PNT and the growth of Mertens Function; quote: " What a compelling notion, that the Mertens Function, which one might envision as something like a random wealk, with the Mobius mu contributing to the summation for M in something like the style of a random coin flip, should be so closely related to the Great Prime Number Theorem, and the Great Conjecture (Riemann Hypothesis) in this way! " The academic community has to really thank them for taking their precious time off their scientific research to educate us by writing this magnificent opus on number theory. There are 9 chapters in this 600 page book with many subchapters: The book starts with a 82 page story on Primes, followed by Number Theoretical tools (34 pp), Recognising primes and composites (56 pp), primality proving (52 pp), Exponential …
