“I have no need of proof. The laws of nature, unlike the laws of grammar, admit of no exception.”

“I wish to establish some sort of system not guided by chance but by some sort of definite and exact principle.”

“In science we must all submit not to what seems to us attractive from one point of view or another, but to what represents an agreement between theory and experiment.”

“We should still expect to discover many unknown simple bodies; for example, those similar to aluminum and silicon, elements with atomic weights of 65 to 75.”

“I suppose when my unknown elements are found, more people will pay us attention.”

“To burn oil!.. You can fuel with money as well.”
