# Really Big Numbers

Richard Evan Schwartz

‘Infinity is farther away than you thought.’

Start with the number one and then move on to millions then to billions then to nonillions then to googols and then to plexes. Did you know that there are about 40 000 ways to place just three counters on a chess board? Or that if the approximately 7 billion people on earth all lined up about a foot apart (it is a US book) they would circle the equator around 50 times? Or that writing a googolplex in long form would be physically impossible since doing so would require more paper than could be contained in the entire known universe?

Each page is a bright, colourful and quirky graphic with accompanying text. The author, a university mathematics professor, not only explains really big numbers but illustrates them with interesting and unusual examples. A book that explores exponential notation, the logic behind naming of numbers and the sheer fascination of numbers so big that they are difficult to imagine.
