The History of Simulation Experiments

Some of the earliest attempts to simulate the Universe did not use computers at all. For example, in the 1960s, researchers at Lund University built a laboratory full of light bulbs to simulate the motion of stars in a galaxy. By measuring the intensity of light from the bulbs, they could use the inverse square law to approximate the forces of gravity.

These early "experiments" pioneered techniques like the "drift step" and "kick step" that are still used in modern simulations. The idea is to split up the complex motions into discrete steps - first calculating the forces, then moving the objects along their trajectories.
