 | TODAY IN SCIENCE HISTORY NEWSLETTER - 4 AUGUST |
| Feature for Today |
 On 4 Aug 1863, Alexander George McAdie was born. As an American meteorologist, he is remembered for his exploration of high altitude air conditions, invention of frost-proofing devices for fruit growers, studies of atmospheric smoke pollution, and urging the adoption of the metric system in meteorology. He also investigated atmospheric electricity, auroral phenomena, lightning. Oh! — and was interested in seismology, too.Yet, he still found time to write science articles for popular magazines on these topics. Several of his articles are introduced on this index page. They include a memoir upon John Muir's death. McAdie's name is probably unknown or only vaguely known to you. But as an example of a scientist beavering away in his field and communicating about it to the lay person, his writings are worth your attention. |
