Book of the Day

On 25 Jun 1799, David Douglas was born, the Scottish biologist whose name is remembered for the Douglas fir tree, one of 240 species of plants he established in Britain following botanical expeditions abroad. He died young and tragically - at age 35 he was gored to death by a wild bull already in the cattle trap into which he fell by accident. Today's Science Store pick is: Traveler in a Vanished Landscape: The Life and Times of David Douglas, by William Morwood. Available Used from $0.92 (as of time of writing).

Yesterday's pick: A Different Approach to Cosmology, by Fred Hoyle, G. Burbidge and J. V. Narlikar.

	"I am absolutely enraptured by the atmosphere of a wreck. A dead ship is the house of a tremendous amount of life—fish and plants. The mixture of life and death is mysterious, even religious.

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
	Johannes Hans Daniel Jensen, born 25 Jun 1907, was a German physicist who proposed a theory for the structure of protons and neutrons within the nucleus which won him a share of the 1963 Nobel Prize in physics. What is the structure he proposed for the nucleus?
	On 25 Jun 1864, Walther Hermann Nernst was born, who was a German scientist who was one of the founders of modern physical chemistry. In 1906, Nernst showed that it is possible to determine the equilibrium constant for a chemical reaction from thermal data, and in so doing he formulated what he himself called the third law of thermodynamics. This states that a certain quantity approaches zero as the temperature goes towards absolute zero. For this, he was awarded the 1920 Nobel Prize in Chemistry. What is this thermodynamic quantity?
Deaths
	A certain French naval officer, (1910-1997) was well-known as oceanographer, marine biologist and ocean explorer, known for his extensive underseas investigations. He was co-inventor of the aqualung which made SCUBA diving possible. In 1945 he founded the French Navy's Undersea Research Group. *Can you name this man?*
	Sir John Boyd Orr (1880-1971) was a Scottish scientist and authority on nutrition. In 1936, he published a report, Food, Health and Income, a dietary survey by income groups made during 1935. It showed that the cost of a diet fulfilling basic nutritional requirements was beyond the means of half the British population and that 10 percent of the population was undernourished. He was director general of the United Nations Food and Agriculture Organization (1945-48). He was awarded a Nobel Prize in 1949 for his efforts to eliminate world hunger. *Which category of the Nobel Prize was he awarded ?*
Events
	In 1903, Marie Curie went before the examination committee for her Ph.D. How many years passed before she was awarded her first Nobel Prize?
	In 1997, the Russian space-station suffered a near-fatal mishap when a Progress ferry being docked via remote control accidentally rammed into the Spektr science module, putting a hole in the pressure vessel and damaging its solar arrays beyond use. To salvage the station, which consisted of a core, a connecting node, and five science modules, crew members severed electrical and data connections between Spektr and the rest of the station and then sealed off the module. They saved the station but lost about half of their electrical power. What is the name of this space station?
