+ | ===== Diophantus ===== | ||
+ | |||
+ | The Greek Diophantus is sometimes called the father of algebra. A puzzle was written about him by Metrodorus: | ||
+ | |||
+ | 'Here lies Diophantus,' the wonder behold. | ||
+ | Through art algebraic, the stone tells how old: | ||
+ | 'God gave him his boyhood one-sixth of his life, | ||
+ | One twelfth more as youth while whiskers grew rife; | ||
+ | And then yet one-seventh ere marriage begun; | ||
+ | In five years there came a bouncing new son. | ||
+ | Alas, the dear child of master and sage | ||
+ | After attaining half the measure of his father's life chill fate took him. After consoling his fate by the science of numbers for four years, he ended his life.' [[http://en.wikipedia.org/wiki/Diophantus#Biography|W]] | ||
+ | |||
+ | How old was Diophantus when he died? ((Dr. W, Apr 8)) | ||

+ | ===== One Family, One Boy ===== | ||
+ | |||
+ | Suppose a group of Chinese families try to change the usual "one family, one child" policy. The want to make it so that each family has one boy. Under the new policy, if the first child is a boy, that will be the family's only child. If they have a girl first, they can have another child. If the second child is a boy, they can not have any more children. This way, each family will continue having children until they get a boy, then they must have no more children. If this new policy is put in place, what will be the distribution of boys and girls in China after many years? ((Junming Dio, Apr 15)) | ||
