Newsletter for Tuesday 1 July


TODAY IN SCIENCE HISTORY
NEWSLETTER - 1 JULY

Feature for Today
On 1 July 1818, Ignaz Semmelweis was born. You probably don't know his name. You should. His discovery was of life-saving significant. Joseph Lister may ring a bell in your mind for introducing antiseptic procedures. But Semmelweis was already onto it before Lister. In the article Pathfinders in Medicine: Semmelweis, the Obstetrician you'll learn how he realized the necessity of handwashing between making an autopsy of a deceased, often infected person, and going to attend to the next childbirth. Women were dying in large numbers due to rampant infection in hospitals. He solved that where he worked. But too many in the medical profession were not ready to learn from him. As a pioneer, he is now a hero, but then widely ignored, even despised by many. He died tragically too.

So, if the name is unfamiliar to you, honour his memory, by reading this biographical article from 1912.

On 1 July 1886, the Tribune newspaper of New York City began the first commercial use in the U.S. of a new kind of machine (which you'll likely name in the quiz below). The image shows one of many similar parts used with this machine.

It was an important advance, and fully described in an interesting article in The Manufacturer and Builder (1889).

Book of the Day
On 1 Jul 1913, the Lincoln Highway Association was formed in the U.S. to promote a coast-to-coast road to be known as the Lincoln Highway. The need for good roads led to the federal government building roads and the creation of numbered U.S. routes in the 1920s. Today's Science Store pick is: The Lincoln Highway: Coast to Coast from Times Square to the Golden Gate, by Michael Wallis and photographer Michael S. Williamson, who take you along this important early road from New York City to San Francisco Bay presenting oft-forgotten and offbeat sights and tales of an America bypassed by superhighways.
 Price $19.95, save 32%, New $13.75. Also a
vailable Used from $11.44 (as of time of writing).

Yesterday's pick: Sir Joseph Dalton Hooker: Traveller and Plant Collector, by Ray Desmond.

Quotations for Today

"Advocacy of leaf protein as a human food is based on the undisputed fact that forage crops (such as lucerne) give a greater yield of protein than other types of crops. Even with connventional food crops there is more protein in the leafy parts than in the seeds or tubs that are usually harvested."
- Norman Wingate Pirie, British biochemist and virologist (born 1 Jul 1907) Quotes Icon
"On foundations we believe in the reality of mathematics, but of course, when philosophers attack us with their paradoxes, we rush to hide behind formalism and say 'mathematics is just a combination of meaningless symbols,'... Finally we are left in peace to go back to our mathematics and do it as we have always done, with the feeling each mathematician has that he is working with something real. The sensation is probably an illusion, but it is very convenient."
Jean Dieudonn�, French mathematician and educator (born 1 Jul 1906) Quotes Icon

"To see every day how people get the name ‘genius' just as the wood-lice in the cellar the name ‘millipede'—not because they have that many feet, but because most people don't want to count to 14—this has had the result that I don't believe anyone any more without checking."
- Georg Christoph Lichtenberg, German physicist and writer (born 1 Jul 1742) Quotes Icon

Louis Bl�riot, born 1 Jul 1872, was a French aviator who made the world's first over-water flight in a heavier-than-air craft. As a successful inventor of automobile lights and accessories, he had his own funds available to turn his interest in aviation. After experimenting with gliders and light-engine airplanes of various designs, on 25 Jul 1909 he flew his Bl�riot XI monoplane on his historic crossing.
What body of water did he cross?
Gottfried Wilhelm Leibniz, born 1 Jul 1646, was a German philosopher, mathematician, and political adviser. Through meeting with such scholars as Christian Huygens in Paris and with members of the Royal Society, including Robert Boyle, during two trips to London in 1673 and 1676, Leibniz was introduced to the outstanding problems challenging the mathematicians and physicists of Europe. He independently discovered (published 1684) certain mathematical procedures, but became involved in a bitter priority dispute with Isaac Newton, whose similar ideas were developed earlier (1665), but published later (1687).
What mathematical idea did they independently invent?
Deaths

A U.S. engineer and architect (1895-1983) developed the geodesic dome, the only large dome that can be set directly on the ground as a complete structure, and the only practical kind of building that has no limiting dimensions.

An American inventor of the vulcanization process (1800-1860) made possible the commercial use of rubber. Originally the use of rubber was limited since it would freeze hard in winter and become gummy in summer. After years of persistent experimentation, he mixed and baked sulfur and rubber together, creating a tough, cured compound that could withstand the heat and stress. A rubber company was named in his honour.
