Classical mechanics includes both Newtonian and relativistic mechanics. In Newtonian physics, gravity is an attractive force, which acts at a distance between all objects; and can be represented as a universal gravitational field.… Continue reading GR: Chicken or egg redux

These stories are engaging because of strong characters, their conflict (the essential ingredient of any great story), and the ethical dilemmas over use of such powers. We expect magic in classical fairy tales (or in Harry Potter… Continue reading Magic Exclusion Principle
