Mathematica , known familiarly as the Principia , Isaac Newton
laid out in mathematical terms the principles of time, force,
and motion that have guided the development of modern physical
science. Even after more than three centuries and the
revolutions of Einsteinian relativity and quantum mechanics,
Newtonian physics continues to account for many of the phenomena
