### A man calls home to his wife a...

A man calls home to his wife and says, "Honey I have been asked to go fishing at a big lake up in Canada with my boss and several of his friends. We'll be gone for a week. This is a good opportunity for me to get that promotion I've been wanting, so would you please pack me enough clothes for a week and set out my rod and tackle box. We're leaving from the office and I will swing by the house to pick my things up. Oh! And please pack my new blue silk pajamas."

The wife thinks this sounds a little fishy but being a good wife she does exactly what her husband asked. The following weekend he comes home a little tired but otherwise looking good.

The wife welcomes him home and asks if he caught many fish. He says, "Yes! Lots of Walleye, some Blue gill, and a few Pike. But why didn't you pack my new blue silk pajamas like I asked you to do?"

The wife replies; "I did, they were in your tackle box."

### John Michell

Died 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]
