Feature for Today

Book of the Day

On 14 Apr 1692, Christiaan Huygens was born, Dutch mathematician, astronomer, and physicist, who founded the wave theory of light, discovered the true shape of the rings of Saturn, and contributed to the science of dynamics. Today's Science Store pick is Unrolling Time: Christiaan Huygens and the Mathematization of Nature, by Joella G. Yoder, who offers a detailed account of the discoveries that Huygens made, the way that each of these important discoveries arose from the interaction of Huygens' mathematics and physics, and the role of Huygens in the rise of applied mathematics.. A discussion of Huygens' relationship with other scientists and the priority disputes that sometimes motivated his research help place his work in the context of the period.

Quotations for Today
	"Tedious as it may appear to some to dwell on the discovery of odds and ends that have, no doubt, been thrown away by the owner as rubbish ... yet it is by the study of such trivial details that Archaeology is mainly dependent for determining the date of earthworks." - Augustus Henry Lane-Fox Pitt-Rivers, English archaeologist often called the "father of British archaeology," who stressed the need for total excavation of sites, thorough stratigraphic observation and recording, and prompt and complete publication (born 14 Apr 1827)
	"...great difficulties are felt at first and these cannot be overcome except by starting from experiments .. and then be conceiving certain hypotheses ... But even so, very much hard work remains to be done and one needs not only great perspicacity but often a degree of good fortune." - Christiaan Huygens, Dutch physicist and astronomer (born 14 Apr 1629)
	"As crude a weapon as a cave man's club, the chemical barrage has been hurled against the fabric of life." - American marine biologist, conservationist and writer (died 14 Apr 1964)
