Ramanujan developed an approximate formula in 1918, which helped him spot that numbers ending in 4 or 9 have a partition number divisible by 5, and he found similar rules for partition numbers divisible by 7 and 11. Srinivasa Ramanujan foi um matemático indiano nascido em Erode, uma pequena localidade a quatrocentos quilômetros a sudoeste de Madras, na Índia, em 22 de dezembro de 1887. It has been published in many different forms, and at least 29 proofs have been given. Back before computers were a thing, around 1956, Edsger Dijkstra came up with a way to ﬁnd the shortest path within a graph whose edges were all non-negetive. All these topics form part of what I such a proof is that proving irrationality of π is far from trivial. More generally. Modern Mathematicians. esp ame bra cat eng.
