Science Quotes by Frederick the Great (5 quotes)

I have no fault to find with those who teach geometry. That science is the only one which has not produced sects; it is founded on analysis and on synthesis and on the calculus; it does not occupy itself with the probable truth; moreover it has the same method in every country.
— Frederick the Great

To your care and recommendation am I indebted for having replaced a half-blind mathematician with a mathematician with both eyes, which will especially please the anatomical members of my Academy.
— Frederick the Great
Letter (26 Jul 1766) to Jean le Rond D’Alembert appreciating his recommendation to bring the younger Joseph-Louis Lagrange (age 30) to the Academy of Sciences in Berlin when Leonhart Euler (age 59), vacated the post of director of mathematics. Euler lost the sight of one eye to disease in 1740, and a cataract took the sight of the remaining eye in 1766. As quoted in Florian Cajori, 'Frederick the Great on Mathematics and Mathematicians', The American Mathematical Monthly (Mar 1927), 34, No. 3, 128.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
