Sometimes, physics can be used to create beautiful art. Kinetic art is art that relies on motion to achieve a specific effect. Often that motion is just an application of simple laws of physics. Waves ...
Iterated algorithms are very important for mathematics today. By repeating equations, scientists are finding brand new things out about the natural world (populations, epidemics, etc.). Iterated algor ...
Do you remember the story of the tortoise and the hare? The tortoise and the hare decided to have a race. Everybody, most of all the hare, thought the hare would win the race because he hopped much fa ...
