    He discovered that the volume and pressure of a gas are proportionally related, this law is what we know of as Boyle's Law.
  • Robert Boyle

    Robert Boyle
    Proposed that the sun is at the center and planets including the earth revolve around it instead of the earth being the center and the sun along with other planets revolve around it.
