Most quoted
"We may say that a basic substance is one which has a lone pair of electrons which may be used to complete the stable group of another atom, and that an acid is one which can employ a lone pair from another molecule in completing the stable group of one of its own atoms."
— from Valence and the Structure of Atoms and Molecules, 1923
"I have no patience with attempts to identify science with measurement, which is but one of its tools, or with any definition of the scientist which would exclude a Darwin, a Pasteur, or a Kekule."
— from The Anatomy of Science, 1926
"The essential feature of the theory of relativity is that it introduces a new conception of space and time, not that it modifies the laws of mechanics and electrodynamics."
— from The Anatomy of Science, 1926
All quotes by Gilbert N. Lewis (412)
The only thing that is constant is change.
The more we know, the more we realize how much we don't know.
The secret of success is to be ready when opportunity comes.
The future belongs to those who believe in the beauty of their dreams.
The only limit to our realization of tomorrow will be our doubts of today.
The important thing is not to stop questioning.
The greatest glory in living lies not in never falling, but in rising every time we fall.
The time is always right to do what is right.
The unexamined life is not worth living.
The journey of a thousand miles begins with a single step.
The mind is everything. What you think you become.
The only thing we have to fear is fear itself.
