How to weigh a flatlander in 2D gravity? Newton who laid out a set of mathematical rules to predict the motion of objects from a falling apple to planets orbiting the Sun, however it was Einstein who described how two masses tend to accelerate towards each other; he formulated the general relativity. Flatland is a story written by Edwin Ab... (more) |
