Today is the birthday of Hans Geiger, born in 1882, he is famous for his invention of the Geiger counter, but also for the Geiger-Marsden experiment which led to the discovery of the atomic nucleus. He died in 1945 at age 63.
Jean Perrin, born in 1870 verified Albert Einstein’s explaination of Bownian motion confirming the atomic theory of matter, he died in 1942 at age 71.
Nevill Mott, born in 1905 received the Nobel Prize for his work on the electronic structure of amorphous semiconductors. He died in 1996 at age 90.
Jean-Marie Lehn, born in 1939 he received the Nobel Prize for his synthesis of crpytands.
Johann Deisenhofer, born in 1943, received the Nobel Prize in Chemistry for determining the first crystal structure of an integral membrane protein.
587 587 Antioch Earthquake, 60,000 people killed.
1993 The 6.2 Mw Latur earthquake shook Maharashtra, India with a maximum Mercalli Intensity of VIII which is Severe. The earthquake killed 9,748 people.
2009 The 7.6Mw Sumatra earthquake shook central Sumatra with a maximum Mercalli Intensity of VIII which is Severe, killing 1,115 people. It was a dip-slip earthquake followed by a 6.6 Mw event.
2016 Hurricane Matthew became a category 5 hurricane, making it the strongest hurricane to form in the Caribbean Sea since Hurricane Felix in 2007.
If you insist on using punishment as a training method, start with the least amount of aversive stimuli possible and build up, just don’t go too far.
Today is the birthday of Enrico Fermi, born in 1901, he opened the atomic age by working out the mathematics of the neutron. He immigrated to the United States from Italy during the Hitler years and built the first atomic reactor. When he received the Nobel Prize, he wouldn’t wear the fascist uniform or give the salute. He discovered that thermal neutrons, those that are slowed down are more effective in a controlled chain reaction. He died of cancer at age 53.
1717 An earthquake struck Antigua, Guatemala, destroying much of the city’s architecture and making authorities consider moving the capital to a different city.
1927 St. Louis Tornado Outbreak, 82 people killed.
2009 The 8.1 Mw Samoa earthquake struck with a maximum Mercalli intensity of VI which is Strong. A destructive tsunami followed killing 189 people dead.
There is a fine line between physical punishment and abuse so I say, avoid it and try to use positive reinforcement methods. Hitting a dog should never be used, but some say pronged collars and shock collars are physical punishment; they are but they might be necessary in some situations. Always try the positive methods first.
Today is the birthday Ferdinand Moissan, born in 1852, he received the 1906 Nobel Prize in chemistry for isolating fluorine from its compounds. This is the element used in toothpastes, some places put it in drinking water to prevent tooth decay and it is used in Teflon just to name a few uses.
