The Sceptical Chymist: or Chymico-Physical Doubts & Paradoxes is the title of a book by
Robert Boyle, published in
London in 1661. In the form of a dialogue, the
Sceptical Chymist presented Boyle's hypothesis that matter consisted of atoms and clusters of
atoms in motion and that every phenomenon was the result of collisions of particles in motion. For these reasons Robert Boyle has been called the founder of modern
chemistry by
J. R. Partington.
