Scientists are always trying to unify observations into theories and then gather many theories into a higher view that explains several theories at once in the hope of arriving at "a theory of everything," unifying our understanding of the universe in a single equation, formula, or theorem. Newton's laws of gravitation explain much of the work of Kepler's laws of planetary motion and Boyle's law of gases. Quantum mechanics came along and united three of the four fundamental forces: electromagnetism, weak nuclear force, and strong nuclear force.
