Science Quotes by Pafnuty Lvovich Chebyshev, (1 quote)
To isolate mathematics from the practical demands of the sciences is to invite the sterility of a cow shut away from the bulls.
— Pafnuty Lvovich Chebyshev,

Quotes by others about Pafnuty Lvovich Chebyshev, (1)
Chebyshev said, and I say it again. There is always a prime between n and 2n.
[Referring to the theorem known as the Bertrand postulate, partially solved by Joseph Bertrand (1822-1900). Chebyshev produced a complete, but difficult, proof. Paul Erdös gave an elegant new proof at age 18, while a second-year undergraduate.] Rhyme quoted by Béla Bollobás, 'The Life and Work of Paul Erdos", in Shiing-Shen Chern and Friedrich Hirzebruch (eds.) Wolf Prize in Mathematics (2000), Vol. 1, 296.

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) --
