TODAY IN SCIENCE HISTORY
NEWSLETTER - 30 MAY

Feature for Today

On 30 May 1892, Lewis M. Rutherfurd died, the American astrophysicist and spectroscopist who made the first telescopes designed for celestial photography. From his own observatory (built in 1856), he photographed the Moon, Jupiter, Saturn, the Sun, and stars down to the fifth magnitude.

In an Obituary of Lewis Morris Rutherfurd (1892), John K. Rees begins by telling that he was named after Lewis Morris, one of the signers of the Declaration of Independence, from whom his mother was a direct descendent. The author continues with a fine account of this notable astronomer's many contributions in his field.

Book of the Day

On 30 May 1912, Wilbur Wright died, who with his brother Orville had invented the first powered airplane. Today's Science Store pick is: To Conquer the Air: The Wright Brothers and the Great Race for Flight, by James Tobin, who explores the contentiousness at the time from partisans of other pioneers as to whether Samuel Langley or Glenn Curtiss should have greater recognition. Other personalities woven into the narrative include Alexander Graham Bell and Octave Chanute. Available Used from $0.30 (as of time of writing).

Yesterday's pick: Humphy Davy: Life Beyond the Lamp, by Raymond Lamont-Brown

Quotations for Today
	"Scientists tend to resist interdisciplinary inquiries into their own territory. In many instances, such parochialism is founded on the fear that intrusion from other disciplines would compete unfairly for limited financial resources and thus diminish their own opportunity for research." (Naming territorial dominance, greed, and fear of the unknown, as some of the influences on the increasing specialization of science.) - Hannes Alfvén, Swedish astrophysicist (born 30 May 1908)
	"Those individuals who give moral considerations a much greater weight than considerations of expediency represent a comparatively small minority, five percent of the people perhaps. But, In spite of their numerical inferiority, they play a major role in our society because theirs is the voice of the conscience of society." - Leo Szilard, Hungarian-American physicist (died 30 May 1964)
	"Superstition is to religion what astrology is to astronomy; the mad daughter of a wise mother." - Francois Marie Arouet Voltaire, French author (died 30 May 1778)

QUIZ
Before you look at today's web page, see if you can answer some of these questions about the events that happened on this day. Some of the names are very familiar. Others will likely stump you. Tickle your curiosity with these questions, then check your answers on today's web page.
Births
	Aleksey Arkhipovich Leonov, born 30 May 1934, was a Soviet cosmonaut who was the first man to climb out of a spacecraft in space. Voskhod 2 was launched into space carrying Leonov with Pavel Belyayev aboard. On the second orbit Leonov left the spacecraft through the air lock while still tethered to the vessel. He took motion pictures and practiced moving outside of the spacecraft for 10 minutes. Voskhod 2 made 17 orbits at about 110 miles (177 km) above earth. Ten years later, Leonov commanded the Soviet Soyuz craft that linked in orbit with a U.S. Apollo craft. *In what decade did this first space walk take place?*
	Joseph William Kennedy, born 30 May 1916 was an American scientist, one of four co-discoverers of a new element which was produced from uranium oxide bombarded with deuterons in a cyclotron at the Univ. of California at Berkeley. Subsequently, on 28 Mar 1941, Glenn Seaborg, Emilio Segrè and Joseph Kennedy demonstrated that this element, like U235, is fissionable with slow neutrons, thus neutrons of any speed, which implies it's a potential fission bomb material. After working with Seaborg, Kennedy was chosen by J. Robert Oppenheimer to lead the Chemistry Division of the Manhattan Project. *What was this element?*
Deaths
	A French inventor (1914-1994) built his business empire by creating throwaway Bic pens, razors and lighters. In 1945, he and his friend, Edouard Buffard, acquired an empty factory shell near Paris, France, and soon developed a thriving business, producing parts for fountain pens and mechanical lead pencils. Later, he spent two years developing his ballpoint pen design, and in 1949, he was able to produce a reliable, low cost ballpoint pen. In 1973 the Bic® Lighter was introduced in the U.S., followed by Bic® Shavers, first introduced in 1976. *Can you name this inventor?*
	Leo Szilard (1898-1964) was a Hungarian-born American physicist who, with Enrico Fermi, designed the first nuclear reactor that sustained nuclear chain reaction. *In what decade was his nuclear reactor built?*
Events
	In 1959, the first of a new craft made its first trip at Cowes on the Isle of Wight. It was designed by Sir Christopher Cockerell and built by Saunders-Roe. The invention was considered initially only for military use, but was released for civilian use in 1959. On 25 Jul 1959, the prototype crossed the English Channel. What was the new craft made its first trip?
	In 1821, a fire hose of cotton web lined with rubber was patented by James Boyd of Boston, Mass. He invented it to replace another form of hose then in use. What was the material used for the older style hose?
	In 1898, Morris William Travers, an English chemist, while working with Sir Willam Ramsay in London, discovered a new element. Its name derives from the Greek word for "hidden." It was a fraction separated from liquified air, which when placed in a Plücker tube connected to an induction coil yielded a spectrum with a bright yellow line with a greener tint than the known helium line and a brilliant green line that corresponded to nothing seen before. What was this new element?
