Ramanujan said that he received his formulas from God. This book is dedicated to all those who find Ramanujan’s π formulas beautiful to look at:
(where Poch(n) refers to the Pochhammer notation described in chapter 2)
“Truly the gods have not from the beginning revealed all things to mortals, but by long seeking, mortals make progress in discovery.”
—Xenophanes of Colophon (c. 500 B.C.)
“Every blade of grass has its angel that bends over it and whispers, ‘grow, grow.’”
—Talmudic commentary Midrash Bereishis Rabbah, 10:6
Acknowledgments
I thank Brian Mansfield for his wonderful cartoon diagrams that appear throughout the book. Over the years, Brian has been helpful beyond compare.
Numerous people have provided useful feedback and information relating to the solutions to my puzzles; these individuals include Dennis Gordon, Robert Stong, Paul Moskowitz, Joseph Pe, Daniel Dockery, Mark Nandor, Mark Ganson, Nick Hobson, Chuck Gaydos, Graham Cleverley, Jeffrey Carr, Jon Anderson, “Jaymz” James Salter, Chris Meyers, Pete Barnes, Steve Brazzell, Steve Blattnig, Edith Rudy, Eric Baise, Martie Saxenmeyer, Bob Ewell, Teja Krasek, and many more. I discussed some of the original puzzles in this book at my Pickover Discussion Group, located on the Web at groups.yahoo.com/group/CliffordPickover , and I thank the group members for their wonderful discussions and comments.
Many of the fancy formulas derived by the Indian mathematician Srinivasa Ramanujan come from Calvin Clawson’s Mathematical Mysteries , Bruce Berndt’s Ramanujan’s Notebooks (volumes 1 and 2), and various Internet sources. With respect to some of the elegant prime number formulas, Clawson cites Paulo Ribenboim’s The Book of Prime Number Records , second edition (New York: Springer, 1989), and The Little Book of Big Primes (New York: Springer, 1991). Calvin Clawson’s Mathematical Mysteries and David Wells’s various Penguin dictionaries provide a gold mine of mathematical concepts. A few problems in this book draw on, update, or revise problems in my earlier books, with information provided by countless readers who spend their lives tirelessly tackling mathematical conundrums.
Other interesting sources and recommended reading are given in the reference section. Numerous Web sites are proliferating that give comprehensive mathematical information, and my favorites include Wikipedia, the Free Encyclopedia ( wikipedia.com ), Ask Dr. Math ( mathforum.org/dr.math/ ), The MacTutor History of Mathematics Archive ( www.gap-system.org/~history/ ), The Published Data of Robert Munafo ( www.mrob.com/pub/index.html ), and MathWorld ( mathworld.wolfram.com ).
Introduction
“An equation means nothing to me unless it expresses a thought of God.”
—Srinivasa Ramanujan (1887-1920)
The Ramanujan Code
“An intelligent observer seeing mathematicians at work might conclude that they are devotees of exotic sects, pursuers of esoteric keys to the universe.”
—Philip Davis and Reuben Hersh, The Mathematical Experience , 1981
Readers of my popular mathematics books already know how I feel about numbers. Numbers are portals to other universes. Numbers help us glimpse a greater universe that’s normally shielded from our small brains, which have not evolved enough to fully comprehend the mathematical fabric of the universe. Higher mathematical discussions are a little like poetry. The Danish physicist Niels Bohr felt similarly about physics when he said, “We must be clear that, when it comes to atoms, language can be used only as in poetry.”
When I think about the vast ocean of numbers that humans have scooped from the shoreless sea of reality, I get a little shiver. I hope you’ll shiver, too, as you glimpse numbers that range from integers, fractions, and radicals to stranger beasts like transcendental numbers, transfinite numbers, hyperreal numbers, surreal numbers, “nimbers,” quaternions, biquaternions, sedenions, and octonions. Of course, we have a hard time thinking of such queer entities, but from time to time, God places in our midst visionaries who function like the biblical prophets, those individuals who touched a universe inches away that most of us can barely perceive.
Srinivasa Ramanujan was such a prophet. He plucked mathematical ideas from the ether, out of his dreams. Ramanujan was one of India’s greatest mathematical geniuses, and he believed that the gods gave him insights. These came in a flash. He could read the codes in the mathematical matrix in the same way that Neo, the lead character in the movie The Matrix , could access mathematical symbols that formed the infrastructure of reality as they cascaded about him. I don’t know if God is a cryptographer, but codes are all around us waiting to be deciphered. Some may take a thousand years for us to understand. Some may always b
