Lighting the way with Parrondo’s paradox
In science, paradoxes often appear when familiar rules are pushed into unfamiliar territory. One of them is Parrondo’s paradox, a curious mathematical result showing that when two losing strategies are combined, they can produce a winning outcome. This might sound … Continue reading

Sharks don’t do math
From ’Sharks hunt via Lévy flights’, Physics World, June 11, 2010: They were menacing enough before, but how would you feel if you knew sharks were employing advanced mathematical concepts in their hunt for the kill? Well, this is the … Continue reading

A not-so-random walk through random walks
Though I’ve been interested of late with the idea of random walks, I was introduced to the concept when, more than two decades ago, I stumbled across Conway’s Game of Life, the cellular automaton built by John Conway in 1970. … Continue reading
