The Irrationals a Story of the Numbers You Can't Count on

Princeton, NJ: Princeton University Press, 2012. 5th Printing. Paperback. B&W Illustrations; This is a trade paperback book. The book is in Very Good+ condition and was issued without a dust jacket/ The corners of the book covers have some light bumping and curling. The text pages are clean and bright. "In mathematics, the irrational numbers are all the real numbers which are not rational numbers, the latter being the numbers constructed from ratios (or fractions) of integers. When the ratio of lengths of two line segments is an irrational number, the line segments are also described as being incommensurable, meaning that they share no "measure" in common, that is, there is no length ("the measure") , no matter how short, that could be used to express the lengths of both of the two given segments as integer multiples of itself. Among irrational numbers are the ratio p of a circle's circumference to its diameter, Euler's number e, the golden ratio f, and the square root of two; in fact all square roots of natural numbers, other than of perfect squares, are irrational.

"In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. The theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation": a 2 + b 2 = c 2 , {displaystyle a^{2}+b^{2}=c^{2}, } a^{2}+b^{2}=c^{2}, where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides.".

The exact origin of the abacus is still unknown. Today, abacuses are often constructed as a bamboo frame with beads sliding on wires, but originally they were beans or stones moved in grooves in sand or on tablets of wood, stone, or metal.
