Via the Seriously, Science? blog comes what looks like a pretty bad paper: Is poker a game of skill or chance? A quasi-experimental study Gerhard Meyer, Marc von Meduna, Tim Brosowski, Tobias Hayer Due to intensive marketing and the rapid … Continue reading
Chances are you’ve seen Conway’s Game of Life, the checkerboard cellular automaton featuring stable structures, replicators, and all sorts of cool designs. (Plenty of implementations available online.) It’s called “life” because the processes of movement and evolution bear some tangential … Continue reading
A short two-person dance, with a twist. Or more accurately, a shear: time is remapped so that there is a delay that increases as you move from the top of the frame down to the bottom. Or in math: (x’, … Continue reading
