So many thought-provoking questions are posed and
answered in this beautifully illustrated book. Author
Clifford A. Pickover reveals the magic and mystery behind
some of the most significant mathematical milestones as well as the
oddest objects and ideas humanity has ever contemplated,
beginning in 150 million B.C. and ending with the latest
cutting-edge breakthroughs.
Mathematics has permeated every field of scientific endeavor. It can be used to explain the colors of the sunset or the architecture of our brains, and help us explore subatomic quantum realities and image faraway galaxies. Notable formulas and mathematical concepts are accompanied by fascinating facts about mathematicians' lives and real-world, practical applications of theorems. Journey with Pickover as he traces 250 achievements like ancient ant "odometers," the first abacus, the discovery of computer-generated fractals, and the quest for new dimensions. Here also are remarkable thinkers from Pythagoras and Euclid to modern-day math icon Martin Gardner and cosmologist Max Tegmark. Chronologically organized, each entry is short enough to digest in a few minutes and is presented along with a striking full-color image. "For me," writes Pickover, "mathematics cultivates a perpetual state of wonder about the nature of mind, the limits of thoughts, and our place in this vast cosmos."

The Math Book features both the Rubik's Cube and the fractal Menger Sponge.
Here is a Menger sponge:
My favorite combination of the Rubik's Cube and Menger Sponge, far too difficult for any human to solve, is the "Menger Rubik's Cube," pictured at right, by Petter Duvander. You can learn more about this "Mengerubik Cubesponge" here. Imagine a race of mathematician aliens attempting to solve the Cube at all size scales. Imagine walking with someone you love along its hidden and mysterious interstices.
Book Reviews"I have often said that a good book is not merely written or compiled, it is crafted. That is, the book is designed for a specific audience and the textual and sensory format is carefully chosen for that audience. Clifford Pickover�s latest venture into the history of mathematics is such an endeavor. This is a wonderful book... excellent, stimulating and inspiring.... Highly recommended.... a tour de force of mathematical ideas" -- Frank J. Swetz, Mathematical Association of America - Book review at The Australian: "Clifford A. Pickover is author of more books than there are decimal places in pi. As his title suggests, Pickover, well, picks over all the best numerical oddities in chronological order, beginning at 150 million BC with the development of the odometer by ants... My longtime rave fave is the Mobius strip�. Small children and the inebriated will be amazed." - Leigh Dayton, The Australian (newspaper)
- Radio interview at Math Factor - Book review at Midwest Book Review: "Amazing.... gorgeous.... fascinating.... thoroughly enjoyable.... beautiful.... fun!
- Book review at Seed Magazine:
"Handsome, image-filled volume.... Pickover, a bona fide polymath who has written more than 40 books, elegantly sums up each mathematical feat...
Entertaining introduction to many strange and surprising ideas....
The book lets readers glimpse the history and development of mathematics and leaves a sense of awe at just how far the field has come." - Book review at Boing Boing: "A palace filled with awe-inspiring curiosities...." - Book review at Neatorama: "A thoroughly enjoyable walk through the history of mathematics with each milestone narrated by Pickover in a short and sweet fashion..." - Book review at Political: "Clifford... sees patterns in everything he looks at, and thinks in logical ways that the average person would scratch their head about. Some could call a man like Clifford obsessed. Whatever he is, his research is impeccable." - Book review at Dr. Dobbs: Delightful�. a truly enjoyable read, approachable by anyone with a curiosity of how numbers have shaped the world we live in�. Beautiful� clear, stunning� Permits the concepts to percolate, savored and appreciated. This is unlike any math book I've read before. There are so many unique facts and stories collected in this work that it demands to be re-read. The educational journey it offers is so memorable and rewarding�. The Math Book would make a memorable gift for any person in a technical field (especially in the realm of computers). I highly recommend this book and look forward to future compilations that Dr. Pickover may have on the horizon. "A marvelous popular trot through some 250 great mathematical conundrums.... with wonderfully exotic names such as the Quadrature of the Lune, Borromean Rings, and Fermat's Spiral." --Sydney Morning Herald "Clifford Pickover�s enthusiasm for all things mathematical is contagious! And each page of this stunning gift book is a testament to the sheer beauty�both intellectual and aesthetic� of the field as seen through his eyes. From evidence of a built-in �pedometer� in an ancient species of ant (dating from more than 150 million years ago) to the Mathematical Universe Hypothesis (advanced in 2007), this chronologically organized tour through �250 milestones in the history of mathematics� provides a concise explanation of the featured theorem/formula/discovery alongside a colorfully evocative illustration. The perfect present for mathematicians and number crunchers, The Math Book also offers an accessible and inspiring survey of major mathematical concepts�and their real-world relevance�for English-major types." - Bas Bleu "Pickover has scoured the millennia and the universe for milestones in maths, and has produced a thought-provoking and entertaining book." -- The Newcastle Herald. Nice entry for The Math Book in the "Signals" gift catalogue, along with math mug. |

I've
compiled the following list that identifies some of the material I used to
research and write this book. Occasionally, I also provide a few extra notes
(♪) of clarification in this section, which includes information culled from
books, journals and Web sites. As many
readers are aware, Internet Web sites come and go. Sometimes they change
addresses or completely disappear. The
Web site addresses listed here provided valuable background information when
this book was written. You can, of
course, find numerous other web sites relating to these mathematical marvels
and milestones using standard Web search tools.
If I have overlooked an interesting or
pivotal moment in mathematics that you feel has never been fully appreciated,
please let me know about it. Just visit my web site pickover.com, and send me
an e-mail explaining the idea and how you feel it influenced the mathematical
world. Perhaps future editions of the
book will include mathematical marvels such as: (1) the Gomboc, a special kind
of three-dimensional object that always tips itself back into a "standing"
position as if by magic, (2) the ancient Chinese texts The Nine Chapters on
the Mathematical Art and The Suan Shu Shū (Writings on
Reckoning), the later of which was written on 190 bamboo strips, (3) the Frobenius postage stamp problem, posed by English
mathematician James Sylvester in 1884 as a money-changing problem, (4) tangram
dissection puzzles, and (5) the ideas of Sophie Germain, one of the great
mathematicians of the early 19th century who considered topics related
to Fermat's Last Theorem and other areas in number theory.

Pythagoras Founds Mathematical Brotherhood (530 BC)
♪ Philosopher Bertrand Russell once wrote that Pythagoras was intellectually one of the most important men that ever lived, both when he was wise and when he was unwise. Pythagoras was the most puzzling mathematician of history because he founded a numerical religion whose main tenants were transmigration of souls and the sinfulness of eating beans, along with a host of other odd rules and regulations.
����� According to Jim Holt, "Mathematicians believe in God at a rate two and a half times that of biologists.� Most mathematicians believe in heaven. Not a heaven with angels, but one populated by the abstract objects they devote themselves to studying: perfect spheres, infinite numbers, the square root of minus one and the like. Moreover, they believe they commune with this realm of timeless entities through a sort of extrasensory perception. Mathematicians who buy into this fantasy are called �Platonists'."

Golden Ratio (1509)
♪ The origin of the term "golden ratio" is disputed but appears to emerge in the twelfth century. Although the recent history of the golden ratio was triggered by Luca Pacioli's Divina Proportione (1509), ancient Greek mathematicians studied the ratio much earlier because it frequently appeared in geometrical studies. Mario Livio writes, "Some of the greatest mathematical minds of all ages, from Pythagoras and Euclid in ancient Greece, through the medieval Italian mathematician Leonardo of Pisa and the Renaissance astronomer Johannes Kepler, to present-day scientific figures such as Oxford physicist Roger Penrose, have spent endless hours over this simple ratio and its properties."
����� Technically speaking, the artistic figure depicts a Fibonacci spiral, based on consecutive terms of a Fibonacci sequence. Because the ratios of consecutive terms in the Fibonacci series approach v, the two spirals are quite similar in appearance.

Using computer simulations, the researchers also showed that other ellipsoid packings result in random packing densities approaching that of the densest sphere packings (nearly filling 74% of the space).
In the 1950s, Hungarian mathematician Laszlo Fejes-Toth, showed that the most efficient stacking arrangement of spheres could be determined by examining a finite cluster of spheres. Specifically, he showed that a proof could be completed after analyzing only 50 spheres.

♪ Lissajous curves were actually first studied by the American mathematician Nathaniel Bowditch in 1815 and investigated independently by Jules Antoine Lissajous in 1857.
����� Hal Robinson, in a personal communication to me, notes that we may want to ask if Lissajous' patterns should really be considered "harmonographs," given that such early patterns may not have been recorded as persistent graphs. Note also that in actual harmonographs, the resultant attractive graphs depend on the gradual decay in the oscillations.
The first patent for innovations in harmonograph design appeared in the early 1900s. In the 1960s, Ivan Moscovich was an early pioneer in creating mechanically efficient, large harmonographs by linking pendulums to a vertical surface.

Hilbert's Grand Hotel (1925)
♪ Note that there are certain levels or classes of infinity that the Hilbert's Grand Hotel may not be able to accommodate. Georg Cantor showed that there are infinities too big to be counted, which is essentially what happens when we associate each guest with a room number.
The precise date and origin of Hilbert's Hotel is difficult to determine. Hilbert spoke of this hotel during his lectures in the 1920s, but he did not appear to write about it. His paper "On the Infinite" was delivered in 1925.� Hilbert's Hotel came to wider public attention in George Gamow's entertaining book One, Two, Three... Infinity, originally published in 1947 and revised in 1961.� Gamow writes that the Hilbert's Hotel appeared in Richard Courant's unpublished The Complete Collection of Hilbert Stories. Richard Courant (1888�1972) was a German American mathematician and assistant to Hilbert in Gottingen.

We could marshal the world's best minds and fastest computers, and within a year we could probably calculate the value. If the aliens demanded the Ramsey number for red six and blue six, however, we would have no choice but to launch a preemptive attack."

Penrose Tiles (1973)
♪ Reclusive amateur mathematician Robert Ammann (1946�1994) independently discovered these kinds of tilings at approximately the same time as Penrose. After being layed off from his programming job at the Honeywell corporation, Ammann worked as a mail sorter in a post office. Chorbachi and Loeb (see below) also discuss the occurrence of ancient indications of Penrose tilings.
According to Branko Gr�nbaum and G. C. Shephard, "in 1973 and 1974 Roger Penrose discovered three sets of aperiodic prototiles." For example, the first set, denoted by P1, consists of six tiles based on rhombs, regular pentagons, pentacles and �half-pentacles', with edges, modified by projections and indentations. The second set of aperiodic tiles, denoted by P2, "was discovered by Penrose in 1974 and is more remarkable than the first in that it contains only two tiles." The third set, denoted by P3 and consisting of two rhombs, was derived from the P2 tiling in 1974.

The Quest for Lie Group E8 (2007)
♪ Also in 2007, physicist A. Garrett Lisi speculated that E8 explained how the various fundamental particles in physics may result from different aspects of the strange and beautiful symmetries of E8. In particular, he found a way to place the various elementary particles and forces on the 248 points of E8. Twenty gaps remained, which he populated with "notional particles," such as those predicted to be associated with gravity. It is possible that Lisi's highly speculative theory, or similar theories, are complementary to string theory rather than an alternative to string theory.
����� In 2008, Scientific American featured a news story skeptical of Lisi's E8 theory; nonetheless, it is fascinating the degree to which mathematics is used to explore the fabric of reality. Albert Einstein once remarked that he sought truth in equations and then trusted that experiments would one day verify his theories. "Our experience hitherto justifies us in believing that nature is the realization of the simplest conceivable mathematical ideas," Einstein wrote. "I am convinced that we can discover by means of purely mathematical constructions the concepts and laws connect them with each other."

Mathematical Universe Hypothesis (2007)
♪ Tegmark's theory was partly based on a talk given at the symposium "Multiverse and

Theory: Toward Ultimate Explanations in Cosmology" held on
����� The theorist A. Garrett Lisi speculates in Zeeya Merali's "Is Mathematical Pattern the Theory of Everything?": "I think the universe is pure geometry -- basically, a beautiful shape twisting around and dancing over space-time. Since E8 [a complex, eight-dimensional mathematical pattern with 248 points] is perhaps the most beautiful structure in mathematics, it is very satisfying that nature appears to have chosen this geometry."
����� To my mind, mathematics is a process of discovery. Mathematicians are like archeologists. Physicist Roger Penrose felt the same way about fractal geometry. In his book The Emperor's New Mind, he says that fractals (for example, intricate patterns such as the Julia set or Mandelbrot set) are out there waiting to be found:����
"It would seem that the Mandelbrot set is not just part of our
minds, but it has a reality of its own...�
The computer is being used in essentially the same way that an experimental
physicist uses a piece of experimental apparatus to explore the structure of
the physical world. The Mandelbrot set
is not an invention of the human mind:�
it was a discovery. Like

Konrad Zuse published one of the first works on digital physics that proposed that the
universe is being computed on a discrete "device." (See reference above)
"Clifford Pickover, prolific writer and undisputed polymath, has put together a marvelous reference work.
Its 250 short entries provide a veritable history of mathematics by focusing on its greatest theorems and the geniuses who discovered them.
Topics are chronological, starting with the calculating abilities of ants 150 million years B.C. and ending with Max Tegmark's recent conjecture
that our universe is not just described by math, it is mathematics.
Dr. Pickover's vast love of math, and his awe before its mysteries, permeates every page of this beautiful volume. The illustrations alone are worth the book's price."
