NotesSelect any pattern that can be built in Life – for example, the Waterbear. Begin with a small number of gliders (now 15) in an otherwise empty Game of Life universe. After enough time goes by, those gliders need to build that pattern. No extra leftover debris, no stray scaffolding, just a pure synthesis of whatever you chose.FeedEmbedUnfurl
NotesGetting a computer to draw a shape in the way that a human would requires programming in some imperfection. The simple idea is to add in some randomization of drawing coordinates, which could be done in various ways. Below are two examples of imperfect circles drawn in an HTML5 canvas with JavaScript, where the imperfection has been added through the use of a fractal-like subdivision algorithm. The imperfection can be subtle, but it is enough to make the image appear to be human-drawn. Although the images are quite simple I find them quite nice to look at.Unfurl
Notes"Persi Warren Diaconis (born January 31, 1945) is an American mathematician and former professional magician. He is the Mary V. Sunseri Professor of Statistics and Mathematics at Stanford University. He is particularly known for tackling mathematical problems involving randomness and randomization, such as coin flipping and shuffling playing cards."FeedUnfurl
Notes"Perhaps you have wondered how predictable machines like computers can generate randomness. In reality, most random numbers used in computer programs are pseudo-random, which means they are a generated in a predictable fashion using a mathematical formula. This is fine for many purposes, but it may not be random in the way you expect if you're used to dice rolls and lottery drawings."Unfurl
Notes"In today's class, we'll be exploring the following principles: first, the Pythagorean theorem. Second, the reciprocal relationship between sine and cosine. And third, logarithmic functions and how they relate to me not having a damn clue what I've just said."Unfurl
