The function of mathematics in physical science. From a theoretical concept to a practical tool. Tracing the path of a comet is fixed by the laws of conservation of energy and angular momentum. The law of gravity leads to Einstein's general theory of relativity, into the black hole, and beyond. All physical phenomena of nature are explained by four forces.
Gravity ranges across the universe at large and electricity binds the atoms of all matter.
331 Forces at play in the Physics Theater. Newton's script suggested connections between electricity and magnetism. Acting on scientific hunches, Maxwell saw the matter in a new light. The music and mathematics of nature. The restoring force and inertia of any stable mechanical system cause objects to execute simple harmonic motion, a phenomenon that repeats itself.
