Newsletter for Saturday 17 May


TODAY IN SCIENCE HISTORY
NEWSLETTER - 17 MAY

Feature for Today
On 17 May 1749, Edward Jenner was born, the English surgeon who discovered the method of vaccination for smallpox.

His interest was initiated by hearing tales of milkmaids who had caught the cowpox being immune from smallpox. Thus, he began by investigating cowpox.

He self-published the results of his study as An Inquiry Into the Causes and Effects of...the Cow Pox (1798). By following the link, which is to an abridged version, you again have a chance to wonder, or be impressed, or feel a quiet excitement, as you read the actual words of one of medicine's great researchers.

Book of the Day
On 17 May 1836, Sir Norman Locker was born. Today's Science Store pick is: Science and Controversy: A Biography of Sir Norman Lockyer, by A.J. Meadows. Lockyer left one the world's leading scientific journals, of which he was the Founder Editor, as his lasting memorial. But his life, and controversial theories, are an important part of science history. His ideas were at the forefront of public debate, and ranged from the brilliant to the perverse. This book is a fascinating insight into the eventful life of this eminent Vistorian scientist. Meadows's biography constitutes an important, absorbing and eminently readable narrative of Lockyer's role in transforming the practice and social organization of late Victorian science. New Price $40.00. Also available Used from $3.30 (as of time of writing).

Yesterday's pick: Dam Busters,  by Paul Brickhill.

Quotations for Today
"While the vaccine discovery was progressive, the joy I felt at the prospect before me of being the instrument destined to take away from the world one of its greatest calamities [smallpox], blended with the fond hope of enjoying independence and domestic peace and happiness, was often so excessive that, in pursuing my favourite subject among the meadows, I have sometimes found myself in a kind of reverie."
- Edward Jenner, English surgeon (born 17  May 1749) Quotes Icon
"Geology has its peculiar difficulties, from which all other sciences are exempt. Questions in chemistry may be settled in the laboratory by experiment. Mathematical and philosophical questions may be discussed, while the materials for discussion are ready furnished by our own intellectual reflections. Plants, animals and minerals, may be arranged in the museum, and all questions relating to their intrinsic principles may be discussed with facility. But the relative positions, the shades of difference, the peculiar complexions, whether continuous or in subordinate beds, are subjects of enquiry in settling the character of rocks, which can be judged of while they are in situ only."
- Amos Eaton, American botanist, geologist and lawyer (born 17 May 1776)  Quotes Icon

"I here present the reader with a new sign which I have discovered for detecting diseases of the chest. This consists in percussion of the human thorax, whereby, according to the character of the particular sounds then elicited, an opinion is formed of the internal state of that cavity."
- Josef Leopold Auenbrugger, Austrian physician who developed diagnotic use of percussion of the thora (died 17 May 1809) Quotes Icon

Births

Sir Joseph Norman Lockyer, born 17 May 1836, in 1868 discovered and named the element helium that he found in the Sun's atmosphere before it had been detected on Earth. He also applied the name chromosphere for the sun's outer layer. He discovered, together with P. J. Janssen, the prominences (red flames) that surround the solar disk. He was also interested in the classification of stellar spectra and developed the meteoric hypothesis of stellar evolution. He was the founding editor of a scientific journal that is still being published.
What is the name of the journal of which he was the Founder Editor?
Edward Jenner (1749-1823) was an English surgeon and discoverer of vaccination for smallpox. There was a common story among farmers that if a person contracted a relatively mild and harmless disease of cattle called cowpox, immunity to smallpox would result. On 14 May 1796 he removed the fluid of a cowpox from dairymaid Sarah Nelmes, and inoculated James Phipps, an eight-year-old boy, who soon came down with cowpox. Six weeks later, he inoculated the boy with smallpox. The boy remained healthy, proving the theory. He called his method vaccination. Jenner also introduced the word virus.
Can you explain the origin of his word vaccination?

On a certain 17 May,  the governor of Tennessee signed into law the repeal of the 1925 state law prohibiting the teaching of evolution. The original law had made it "unlawful for any teacher in any of the Universities, Normals and all other public schools of the State which are supported in whole or in part by the public school funds of the State, to teach any theory that denies the story of the Divine Creation of man as taught in the Bible, and to teach instead that man has descended from a lower order of animals." It was this law that was tested in what became known as the "Scopes monkey trial." Scopes was found guilty, but acquitted on a technicality upon appeal.
In what decade was this law repealed?

On 17 May 1912, the London newspaper, The Times, reported that new experimental equipment was in place at Epsom, to be tested in the afternoon of the following day.

What was the equipment?
