“The different branches of science are so intimately connected that the study of one can not be pursued to any great extent without an acquaintance with the others.”

“The seeds of great discoveries are constantly floating around us, but they only take root in minds well prepared to receive them.”

“Information is not knowledge.”

“A man has no right to withhold from the world a discovery, however unimportant he may think it, which may be of use to others.”

“The worth and importance of the institution are not to be estimated by what it accumulates within the walls of its building, but by what it sends forth to the world.”

“It is in the highest degree improbable that the secret of what is called gravitation will ever be discovered.”

“All knowledge is but an approximation.”

“The general mental qualification is scientific conversation.”

“Every movement of the mind is based on some sensation.”
