  • I wish to establish some sort of system not guided by chance but by some sort of definite and exact principle.
  • 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 have no need of proof. The laws of nature, unlike the laws of grammar, admit of no exception.
  • I suppose when my unknown elements are found, more people will pay us attention.

Quotes about MendeleevEdit
