Feature for Today
Thumbnail of Alexander George McAdie

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. Several of the topics above are featured in his articles, which you can find on this index page. They include a memoir upon John Muir's death. An opening paragraph for each may whet your appetite, and you can follow each link to its complete article.

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.


Book of the Day

On 4 Aug 1755, an inventive manufacturer was born, who made his career out of manufacturing pencils. Such a simple object would scarcely seem worthy of a whole book about it, but astonishingly there is. And it’s by an engaging writer, too. Today's book pick is: , by . The author is an engineer who has written much on structural failures of bridges and buildings. Anything he writes is an easy and informative read. In this book, he turns his attention to a lowly, small object, and has produced yet another little gem to read. Petroski traces the origins of the pencil back to ancient Greece and Rome, writes factually and charmingly about its development over the centuries and around the world, and shows what the pencil can teach us about engineering and technology today. Your Webmaster has read it and enthusiastically recommends it.

It is available from Amazon, typically about (As of earlier time of writing - subject to change.)

Thumbnail of William Henry Hudson
I am not a lover of lawns; … the least interesting adjuncts of the country-house. … Rather would I see daisies in their thousands, ground ivy, hawkweed, and even the hated plantain with tall stems, and dandelions with splendid flowers and fairy down, than the too-well-tended lawn.
— William Henry Hudson, English author, naturalist and ornithologist (born 4 Aug 1841). quote icon
