Definition of Chemistry


  1. That branch of science which treats of the composition of substances, and of the changes which they undergo in consequence of alterations in the constitution of the molecules, which depend upon variations of the number, kind, or mode of arrangement, of the constituent atoms. These atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained. Chemistry deals with the changes in the composition and constitution of molecules. See Atom, Molecule.
  2. An application of chemical theory and method to the consideration of some particular subject; as, the chemistry of iron; the chemistry of indigo.
  3. A treatise on chemistry.

Chemistry Quotations

In my school, the brightest boys did math and physics, the less bright did physics and chemistry, and the least bright did biology. I wanted to do math and physics, but my father made me do chemistry because he thought there would be no jobs for mathematicians.
Stephen Hawking

My eyes are constantly wide open to the extraordinary fact of existence. Not just human existence, but the existence of life and how this breathtakingly powerful process, which is natural selection, has managed to take the very simple facts of physics and chemistry and build them up to redwood trees and humans.
Richard Dawkins

I can't explain chemistry. I really can't. I haven't got a clue what it's all about. It just happens. It's like falling in love. You can't explain why you fall in love or explain why it's this particular person.
Elaine Stritch

Psychology, unlike chemistry, unlike algebra, unlike literature, is an owner's manual for your own mind. It's a guide to life. What could be more important than grounding young people in the scientific information that they need to live happy, healthy, productive lives? To have good relationships?
Daniel Goldstein

In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11-dimensional hyperspace.
Michio Kaku
