Man Becomes Acquainted With the Laws of the Universe

Rational mechanics soon became a vast and profound science. The true laws of the collision of bodies, respecting which Descartes was deceived, were at length known. Huyghens discovered the laws of circular motions; and at the same time he gives a method of determining the radius of curvature for every point of a given curve. By uniting both theories, Newton invented the theory of curve-lined motions, and applied it to those laws according to which Kepler had discovered that the planets descr...

 Wizardry Violates the Conservation of Energy

“You turned into a cat! A small cat! You violated Conservation of Energy! That’s not just an arbitrary rule, it’s implied by the form of the quantum Hamiltonian! Rejecting it destroys unitarity and then you get ftl signaling! And cats are complicated! A human mind can’t just visualize a whole cat’s anatomy and, and all the cat biochemistry, and what about the neurology? How can you go on thinking using a catsized brain?” McGonagall’s lips were twitching harder now. “Magic.”...
