TODAY IN SCIENCE HISTORY NEWSLETTER - 5 OCTOBER

Feature for Today

On 5 Oct 1880, William Lassell died, an English astronomer, who was an amateur, but wealthy enough to build his own telescope, and to set up his own observatory at Starfield, near Liverpool, England. An obituary on The Late Mr. William Lassell appeared in The Observatory: A Monthly Review Of Astronomy in Nov 1880. Or, read this shorter article on William Lassell for more information on this enterprising amateur.

Book of the Day

On 5 Oct 1882, Robert H. Goddard was born, an American pioneer in the construction of liquid-fuel rockets for whom NASA's Goddard Space Center is named. Today's Science Store pick is: Rocket Man: Robert H. Goddard and the Birth of the Space Age, by David A. Clary, a biography that details the significance of a scientist that is both complex and fascinating. He has been said to be—in his day—more famous than Einstein or Edison, yet he is the “forgotten man” of the space age. His own government ignored his rocketry until the Germans demonstrated its principles in the V-2 missiles of World War II. Though he is known as the father of rocketry, much of Goddard's pivotal role in launching the Space Age has been largely forgotten by the public. It is available New from $9.16. Used from $0.01. (As of time of writing.). For picks from earlier newsletters, see the Today in Science History Science Store home page.

Quotations for Today
	I picture the vast realm of the sciences as an immense landscape scattered with patches of dark and light. The goal towards which we must work is either to extend the boundaries of the patches of light, or to increase their number. One of these tasks falls to the creative genius; the other requires a sort of sagacity combined with perfectionism. - Denis Diderot, French encyclopedist (born 5 Oct 1713).
	Let me tell you how at one time the famous mathematician Euclid became a physician. It was during a vacation, which I spent in Prague as I most always did, when I was attacked by an illness never before experienced, which manifested itself in chilliness and painful weariness of the whole body. In order to ease my condition I took up Euclid's Elements and read for the first time his doctrine of ratio, which I found treated there in a manner entirely new to me. The ingenuity displayed in Euclid's presentation filled me with such vivid pleasure, that forthwith I felt as well as ever. - Bernhard Bolzano, Czech mathematician and theologian (born 5 Oct 1781).
	There can be no thought of finishing, for aiming at the stars, both literally and figuratively, is the work of generations, but no matter how much progress one makes there is always the thrill of just beginning. - Robert Goddard, American physicist, rocket engineer and inventor (born 5 Oct 1882).
