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.
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.
~~[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
