January 1, 2001, will mark the beginning of a new thousand-year period on earth.But our earth is more than four billion years old, and humans have lived on our planet for perhaps two hundred thousand years.So how can it be the year 2000?The answer is that it is the year 2000 only on the Gregorian calendar. On the Hebrew calendar, the year will be 5760.On the Muslim calendar, the year will be 1420.And on the Chinese calendar, it will be 4698.So what year is it really? It all depends on what calendar you use and when you started counting the years.

Here is the fascinating story of timekeeping: how, over thousands of years, calendars and clocks came to be.

In his clear, informal, engaging style, Isaac Asimov explains historic brainteasers and numerical oddities in the fascinating universe of numbers. From man's first act of counting to higher mathematics, from the smallest living creature to the dazzling reaches of outer space, Asimov is a master at "explaining complex material better than any other living person." (The New York Times) You'll learn: HOW to make a trillion seem small; WHY imaginary numbers are real; THE real size of the universe - in photons; WHY the zero isn't "good for nothing;" AND many other marvelous discoveries, in ASIMOV ON NUMBERS. ...

A wonderful book on numbers and math
Why schools these day's require dry textbooks that cost $$$ instead of this wonderful story of numbers is beyond me.I think you would have triple the number of math lovers if they were all introduced to Isaac Asimov's world at an early age.You will gain a greater appreciation of numbers and the people behind the ideas of mathematic's as you glide through this book.I doubt you will want to put it down, and if you do, your mind will still be puzzling the ideas and concepts that Asimov explains.

The Joy of Counting
Let us return to those dark and thrilling days of yesteryear, the 1960s. I was in high school at that time. We were still using slide rules for mathematical calculations in physics. (You had to keep their edges lubricated with powdered graphite so that they would slip smoothly. Does anybody remember _those_ days?) There was no internet and no Googol website. But I knew what a googol was, and what a googolplex was, and even what Skewes numbers were. I had read an article by Isaac Asimov in the August 1963 issue of _Fantasy and Science Fiction_ called "T-Formation" that dealt with Big Numbers of various kinds.

From other math related articles by Asimov in _F&SF_, I understood why the square root of minus one wasn't _really_ imaginary. I had a rough idea of how the value of pi had been calculated over the years. And I had something of an understanding of why you couldn't square a circle with a straightedge and compass.

There were other things that I didn't grasp so easily. Why was infinity not really a number? And how could you have more than one infinities? My understanding of factorials was very fuzzy. And some mathematicians-- Gottfried Leibnitz, Leonardo Fibonacci, Georg Cantor, Leonard Euler, and Karl Friedrich Gauss-- I knew almost nothing about. (Though the names of Euclid, Archimedes, Pythagorus, and Newton were familiar.)

The articles by Asimov were no substitute for the daily drill in math that my teachers imposed upon me. But they sharpened my thinking about a few concepts, and they gave me my first glimmering of a notion that maybe mathematics was something more than what was presented to us in textbooks. The formulas that we were supposed to memorize didn't represent concepts that sprang full-blown out of the brow of Zeus. They were ideas that _evolved_, with lots of trial and error and refinement. I wasn't ready to admit that math was fun, but I was willing to concede that at times it could be interesting. In short, Asimov's articles gave me an education.

Here are seventeen mathematical essays from _F&SF_ published between September 1959 and June 1966. They are grouped into seven parts: Numbers and Counting (five essays), Numbers and Mathematics (three essays), Numbers and Measurement (two essays), Numbers and the Calendar (two essays), Numbers and Biology (one essay), Numbers and Astronomy (one essay), and Numbers and Earth (three essays). "T-Formation" is here, and most of the others that made an impression on me back then: "The Imaginary That Isn't," "A Piece of Pi," "Tools of the Trade," "Varieties of the Infinite," and "Exclamation Point!" Asimov elsewhere states that this last piece, on factorials, is his all-time favorite math essay.

Perhaps the most amusing article in the book is "Forget It!" It is a review of a 1797 math textbook, explaining why most of its contents are rightfully left out of modern math textbooks. In a related vein, "Nothing Counts" compares the Roman and the Arabic Number systems. And "Pre-Fixing It Up" is an introduction to the metric system. Asimov correctly argues that it is superior in every way to the English system. I remember that at one time I took several education courses on teaching metrics. It was to be the coming thing. But the metric revolution in the United States fizzled out in favor of tradition. Other countries have adopted it, but we still lag behind.

Asimov is fond of writing articles that play with comparisons and measurements, and there are several of these articles here: "That's About the Size of It" (on the relative sizes of animals), "Water, Water, Everywhere" (on the comparative sizes of bodies of water around the world), "Up and Down the Earth" (on geographic heights and depths and bulges), and "The Isles of Earth" (on the different sizes of islands). Herman Melville was known to sneer at science essays loaded with tables and numbers. I found these numerical exercises to be anything but dry.

The two essays on the calendar deal with figures like Julius Ceasar, Charlemagne, Napolean Bonaparte, and George Washington-- figures better known to high school students than many mathematicians. What is the significance of Washington and the calendar? It lies in the answer to this question: When was George Washington's birthday? Read Asimov for greater detail.

The book has one feature that was not in the original magazine columns. It has illustrated sidebars with commentary-- sometimes on historical personages, sometimes on animals, oceans, volcanoes, old mathematical documents. In each case, they give the reader a bit more in the way of informational trivia than would be obtained by the text alone. Today, my knowledge and appreciation of mathematics is much greater than it used to be. But I still return to the essays in this book. I often find that there are details in the Good Doctor's articles that I missed on the first couple of readings. Get this book for yourself. If you are a parent, get a copy for your children. Take the time to go over several chapters with them. Then let them read the rest on their own.

Can numbers be exciting?
Yes!

This is a funny, interesting, eye-opening, highly readable book. Who would have thought that a book about numbers could be so fascinating!

Are ya curious about the Fibonacci sequence?

Can't Get Enough
This is the most concise, humourous book on the history of numbers you will read. Asimov is at his peak with this one. The last couple of chapters lost my interest, but the rest is well worth the money. Written for the layman, but enough fuel for the enthusiast.

One of my favorite books
Every time I read this book (I've read it at least 4 times) I get to achapter that I've read before and I say, "I don't think I'll read thischapter, I'll just skip it and go on to the next one..."But then Iend up reading that chapter and I will think to myself, "That chapterwas AWESOME!Why would I ever think of skipping it?"I love thisbook, I find it hard to put down.Asimov has a way of explainingmathematical concepts in a very compelling way.I'm sad that the book isout of print - I can't find the copy that I read back in high school - surewould love to pick up another copy.As mentioned else where this book is acompilation of articles written by Asimov, mostly in the 60's. ...
