Theoretical Chemistry Quotes (4 quotes)
~~[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.
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.
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.
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.
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.
