Newsletter for Thursday 15 May


TODAY IN SCIENCE HISTORY
NEWSLETTER - 15 MAY

Feature for Today
On 15 May 1857, Williamina Paton Fleming was born, the Scottish-American astronomer who progressed from being a maid for Prof. Edward Pickering, to an assistant in clerical and computational work, and to a pioneer in the classification of stellar spectra.

She trained other women to do mathematical calculations, who were known as the Harvard Computers (and sometimes less flatteringly as Pickering's Harem).

This Obituary of Williamina Paton Fleming was written by Annie Jump Cannon, a Harvard Computer, who learned the skills from Fleming, and made significant contributions to the classification of stars in her own right.

The "Dinky" range of miniature cars and other motor vehicles was added in 1933, followed by and Scalextric. Today's Science Store pick is: Frank Hornby: The Boy Who Made $1,000,000 With a Toy, by M.

Quotations for Today
"It can even be thought that radium could become very dangerous in criminal hands, and here the question can be raised whether mankind benefits from knowing the secrets of Nature, whether it is ready to profit from it or whether this knowledge will not be harmful for it. The example of the discoveries of Nobel is characteristic, as powerful explosives have enabled man to do wonderful work. They are also a terrible means of destruction in the hands of great criminals who lead the peoples towards war. I am one of those who believe with Nobel that mankind will derive more good than harm from the new discoveries."

"It appears, nevertheless, that all such simple solutions of the problem of vertebrate ancestry are without warrant. They arise from a very common tendency of the mind, against which the naturalist has to guard himself,—a tendency which finds expression in the very widespread notion that the existing anthropoid apes, and more especially the gorilla, must be looked upon as the ancestors of mankind, if once the doctrine of the descent of man from ape-like forefathers is admitted. A little reflexion suffices to show that any given living form, such as the gorilla, cannot possibly be the ancestral form from which man was derived, since ex-hypothesi that ancestral form underwent modification and development, and in so doing, ceased to exist."
- Sir Edwin Ray Lankester, English zoologist (born 15 May 1847) Quotes Icon
"Each volcano is an independent machine—nay, each vent and monticule is for the time being engaged in its own peculiar business, cooking as it were its special dish, which in due time is to be separately served. We have instances of vents within hailing distance of each other pouring out totally different kinds of lava, neither sympathizing with the other in any discernible manner nor influencing other in any appreciable degree."
- Clarence Edward Dutton, American geologist (born 15 May 1841) Quotes Icon
