This is the 50th issue of Plus and to celebrate, we've made it especially big. We explore the incredibly life-like images generated by computers and fragile medieval frescoes, find chaos in fluid flows and prime numbers in a sieve, meet the "English Galileo" and a man who's into geeky pop, and learn about the dangers of bacon sandwiches. Plus the usual regular features including book reviews, puzzle and podcasts.
