Mersenne's Numbers (R.T. Gould / Fermat)

Found - a fascinating forgotten work Oddities: A Book of Unexplained Facts (Allan, London 1928) by R.T. Gould. Rupert Thomas Gould (1890 – 1948), was a lieutenant Commander in the British Royal Navy noted for his contributions to horology. While in the navy in WW1 he suffered a nervous breakdown. During long recuperation, he was stationed at the Hydrographer's Department at the Admiralty, where he became an expert on various aspects of naval history, cartography, and expeditions of the polar regions. He gained permission in 1920 to restore the marine chronometers of John Harrison, and this work was completed in 1933. Jeremy Irons played him in Longitude, a dramatisation of Dava Sobel's book about John Harrison Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time, which recounted in part Gould's work in restoring the chronometers.

Something of a polymath, he wrote an eclectic series of books on topics ranging from horology to the Loch Ness Monster. He was a member of the Sette of Odd Volumes (Brother Hydrographer) and the book Oddities is dedicated to the club. He was a science educator, giving a series of talks for the BBC's Children's Hour starting in January 1934 under the name "The Stargazer", and these collected talks were later published. He was a member of the BBC radio panel Brains Trust. He umpired tennis matches on the Centre Court at Wimbledon on many occasions during the 1930s. This is his chapter on Marin Mersenne (and of course Fermat). The reference to Mr R.E. Powers 'an American computer' dates the book, back then it meant 'one who computes..'

MERSENNE'S NUMBERS 

  Many, I have no doubt, have heard of the enthusiastic Don who once proposed a toast to "Pure Scholarship", coupling with it the pious aspiration, "And may it never be of any damned use to anybody". Like most other exemplary and edifying fables, it has been fathered upon many people and located in many places.

  There is one department of human knowledge concerning which we may safely assume that this aspiration will always be fulfilled. The utility of the various branches of mathematics is, generally speaking, in inverse ratio to their purity; and even though the abstruse results of non-Euclidean geometry and similar studies are now finding comparatively practical applications in the Theory of Relativity and quantum mechanics, most of us are willing to take such matters on trust, confident that, even if there is an omitted symbol or other loose screw in the reasoning, no shipwreck, structural collapse, or other practical inconvenience can possibly result.

  And of no branch of mathematics is this more true than of the Theory of Numbers.
