Ramanujan Machine

• Scientists from Technion — Israel Institute of Technology have developed a concept and have named the Ramanujan Machine, after the Indian mathematician.
• It is not really a machine but an algorithm, and performs a very unconventional function.
• With most computer programs, humans input a problem and expect the algorithm to work out a solution.
• With the Ramanujan Machine, it works the other way round. Feed in a constant, for example well-known pi, and the algorithm will come up with a equation involving an infinite series whose value, it will propose, is exactly pi.
• Why named after Ramanujan
• The algorithm reflects the way SrinivasaRamanujan worked during his brief life (1887-1920). With very little formal training, he engaged with the most celebrated mathematicians of the time, particularly during his stay in England (1914-19), where he eventually became a Fellow of the Royal Society and earned a research degree from Cambridge.
• Throughout his life, Ramanujan came up with novel equations and identities —including equations leading to the value of pi — and it was usually left to formally trained mathematicians to prove these.
• In 1987, two Canadian brothers proved all 17 of Ramanujan’s series for 1/pi; two years earlier, an American mathematician and programmer had used one of these formulas to calculate pi up to over 17 million digits, which was a world record at the time (DekaBaruah, Berndt & Chan).
