I was in a couple’s home trying to fix their Internet connection. The husband called out to his wife in the other room for the computer password. “Start with a capital S, then 123,” she shouted back.
We tried S123 several times, but it didn’t work. So we called the wife in. As she input the password, she muttered, “I really don’t know what’s so difficult about typing Start123.”
John MichellDied 21 Apr 1793 (born 1724). British geologist and astronomer who was first to devise a realistic estimate of the distance to the stars, discovered physical double stars, and is considered the father of seismology. After the Lisbon earthquake of 1755 (which killed 70,000 people), he suggested that earthquakes set up wave motion in the earth. He noted the increased frequency of earthquakes in volcanic areas. Michell realized that by comparing the time at which earthquakes are felt, the epicentre could be calculated. He invented a torsion balance, a device to measure very small forces, though died before carrying out its purpose to determine the density of the Earth. His rebuilt apparatus was used by Cavendish to make that measurement, which also gives the gravitational constant).«[Image: Michell torsion balance as used by Cavendish] |
