  许晨阳和一个外国数学家小时候都看过这本作为启蒙，时间长了名字记不住了。已经绝版了，本来有pdf版，还是找到了影印版。好多有趣的细节，挺有意思的书

  多年前的一个下午，在电脑上看完了这本书，只记得当时的心潮澎湃，却对内容已经模糊。我想，如果没看到这本书，我会不会和现在有所不同呢

  In short he (Archimedes) used his mechanics to advance his mathematics. This is one of his titles to a modern mind: he used anything and everything that suggested itself as a weapon to attack his problems.

  Archimedes made his own occasions. Sitting before the fire he would rake out the ashes and draw in them. After stepping from the bath he would anoint himself with olive oil, according to the custom of the time, and then, instead of putting on his clothes, proceed to lose himself in the diagrams which he traced with a finger-nail on his own oily skin.

  ... the common whole numbers 1,2,3 ... are insufficient for the construction of mathematics even in the rudimentary form in which he (Pythagoras) knew it. [...] This was what knocked his theory flat: it is impossible to find two whole numbers such that the square of one of them is equal to twice the square of the other. [...] Actually Pythagoras found his stumbling-block in geometry: the ratio of the side of a square to one of its diagonals cannot be expressed as the ratio of any two whole numbers. This is equivalent to the statement above about squares of whole numbers. In another form we would say that the square root of 2 is irrational, that is, is not equal to any whole number or decimal fraction, or sum of the two, got by dividing one whole number by another.
