Who said: “The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it... That is how we will preserve our planet, commanded to our care by God. That’s what will lend meaning to the creed our fathers once declared.”

Theoretical Chemistry Quotes (4 quotes)

The deepest part of theoretical chemistry must end up in quantum mechanics.
In 'Chemistry', The Feynman Lectures on Physics (1965), Vol. 1, page 3-1.
Science quotes on:  |  Chemistry (353)  |  Deepest (4)  |  End (590)  |  Mechanic (119)  |  Mechanics (131)  |  Must (1526)  |  Quantum (117)  |  Quantum Mechanics (46)

The theory of quantum mechanics also explained all kinds of details, such as why an oxygen atom combines with two hydrogen atoms to make water, and so on. Quantum mechanics thus supplied the theory behind chemistry. So, fundamental theoretical chemistry is really physics.
In 'Introduction', QED: The Strange Theory of Light and Matter (1985), 5.
Science quotes on:  |  All (4108)  |  Atom (355)  |  Behind (137)  |  Chemistry (353)  |  Combine (57)  |  Detail (146)  |  Explain (322)  |  Fundamental (250)  |  Hydrogen (75)  |  Kind (557)  |  Mechanic (119)  |  Mechanics (131)  |  Oxygen (66)  |  Physic (517)  |  Physics (533)  |  Quantum (117)  |  Quantum Mechanics (46)  |  Theory (970)  |  Two (937)  |  Water (481)  |  Why (491)

Theoretical chemistry is a peculiar subject. It is based on an equation that can hardly ever be solved.
'Orbital Update', review of R. McWenny, Methods of Molecular Quantum Mechanics (1989). Nature, 1990, 343, 222.
Science quotes on:  |  Chemistry (353)  |  Equation (132)  |  Orbitals (2)  |  Peculiar (113)  |  Subject (521)

~~[Need source]~~ All theoretical chemistry is really physics; and all theoretical chemists know it.
Webmaster, so far, has been unable to find a primary source that adds the ending clause. (Can you help?) But Feynman certainly several times stated the idea in the opening clause. See, for example, the quote, “The theory of quantum mechanics … supplied the theory behind chemistry. So, fundamental theoretical chemistry is really physics.” on the Richard Feynman Quotes page on this website.
Science quotes on:  |  All (4108)  |  Chemist (156)  |  Chemistry (353)  |  Know (1518)  |  Physic (517)  |  Physics (533)  |  Really (78)  |  Theoretical (22)


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
