Sherlock Holmes and Dr. Watson
Sherlock Holmes and Dr. Watson go on a camping trip, set up their tent, and fall asleep.
Some hours later, Holmes wakes his faithful friend. "Watson, look up at the sky and tell me what you see."
Watson replies, "I see millions of stars."
"What does that tell you?"
Watson ponders for a minute. "Astronomically speaking, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, it tells me that Saturn is in Leo. Timewise, it appears to be approximately a quarter past three. Theologically, it's evident the Lord is all-powerful and we are small and insignificant. Meteorologically, it seems we will have a beautiful day tomorrow. What does it tell you?"
Holmes is silent for a moment, then speaks. "Watson, you idiot, someone has stolen our tent."

Johann von LamontDied 6 Aug 1879 at age 73 (born 13 Dec 1805).Scottish-born German astronomer noted for discovering (1852) that the magnetic field of the Earth fluctuates with a 10.3-year activity cycle, but does not correlate it with the period of the sunspot cycle. From 1 Aug 1840, Johann von Lamont (as director of the Royal Astronomical Observatory in Munich) started regular and permanent observations of the earth's magnetic field. In the 1850's he started making regional magnetic surveys in the kingdom of Bavaria, later extended to other states in south Germany, France, Holland, Belgium, Spain, Portugal, Prussia and Denmark. His central European maps with isolines of geomagnetic elements, reduced to 1854, were the first worldwide. |
