Diophantus’ Age

No one knows much about Diophantus, the Greek mathematician, but in the sixth century a math puzzle purported to give his epitaph:

“This tomb holds Diophantus. Ah, what a marvel! And the tomb tells scientifically the measure of his life. God vouchsafed that he should be a boy for the sixth part of his life; when a twelfth was added, his cheeks acquired a beard; He kindled for him the light of marriage after a seventh, and in the fifth year after his marriage He granted him a son. Alas! late-begotten and miserable child, when he had reached the measure of half his father’s [total] life, the chill grave took him. After consoling his grief by this science of numbers for four years, he reached the end of his life.”

At what age did he die?

Let This Be a Lesson

Martin Kallikak was a youthful soldier in the Revolutionary War. At a tavern frequented by the militia he met a feeble-minded girl by whom he became the father of a feeble-minded son. In 1912 there were 480 known direct descendants of this temporary union. It is known that 36 of these were illegitimates; that 33 were sexually immoral; that 24 were confirmed alcoholics; and that 8 kept houses of ill-fame. The explanation of so much immorality will be obvious when it is stated that of the 480 descendants 143 were known to be feeble-minded, and that many of the others were of questionable mentality.

A few years after returning from the war this same Martin Kallikak married a respectable girl of good family. From this union 496 individuals have been traced in direct descent, and in this branch of the family there were no illegitimate children, no immoral women, and only one man who was sexually loose. There were no criminals, no keepers of houses of ill-fame, and only two confirmed alcoholics. Again the explanation is clear when it is stated that this branch of the family did not contain a single feeble-minded individual. It was made up of doctors, lawyers, judges, educators, traders, and landholders.

Timex had nothing on Jai Singh II. After building this 90-foot sundial, the Indian maharaja always knew the correct time to within half a second — and this was in the early 1700s.

Ben Franklin wrote, “Energy and persistence conquer all things.”

Stupid Nazis

Hitler thought the moon was made of ice. The idea came from an Austrian engineer named Hanns Hörbiger, who had suggested in 1913 that most objects in the solar system were icy, apparently because they’re shiny. No one took this seriously at the time, but German socialists began to support it during the ’20s, and eventually it became official Nazi policy, an alternative to “Jewish” science.

The idea was dismissed again after the war, but it had a strange holding power — as late as 1953 more than a million people in Germany, England and the United States still believed in Hörbiger’s theory.

Maximum Mileage

If you’re really dedicated, it’s possible to travel nearly 6,000 miles in a straight line within the United States.

A trip from Log Point on Elliott Key in Florida to Kure Island in Hawaii would cover 5,859 miles.
