Earnest rutherford and papers and dating

To compare its sensitivity as a detector of electromagnetic waves against that of the standard detector of the time, the coherer, he mounted his detector in the receiving circuit of a Hertzian oscillator–receiver unit and found, as had others before him, that he could detect electromagnetic waves over a few metres even when there was a brick wall between the two circuits.Rutherford was encouraged in his work by Sir Robert Ball, who had been scientific adviser to the body maintaining lighthouses on the Irish coastline; he wished to solve the difficult problem of a ship's inability to detect a lighthouse in fog.In 1893 Rutherford obtained an MA with double first-class honours in mathematics and mathematical physics and in physical science (electricity and magnetism).At this time he boarded with a widow, Mary Newton, who was active in the suffrage movement.From 1890 to 1894 he attended Canterbury College in Christchurch.There he played rugby and participated in the activities of the Dialectic Society (a student debating society) and the Science Society.In 1894 Rutherford returned to Canterbury College where he took geology and chemistry for a BSc degree, awarded in 1895.For the research work required of a candidate for an 1851 Exhibition scholarship, he extended his researches of the previous year to even higher frequencies using the damped oscillatory current obtained from discharging a Leyden jar (an electrical capacitor), either alone or via a Hertzian oscillator.

However, Thomson, who was soon to be the first to discover an object smaller than an atom (the electron), quickly realised that Rutherford was a researcher of exceptional ability and invited him to join in a study of the electrical conduction of gases.This allowed him to return for a further (honours) year during which he took both mathematics and physics, and was influenced by Professor Alexander Bickerton.The physics course required students to undertake an original investigation; Rutherford elected to extend an undergraduate experiment in order to determine if iron is magnetic at very high frequencies of magnetising current.The commercial development of wireless telegraphy was thus left for Guglielmo Marconi.Rutherford developed several ingenious techniques to study the mechanism whereby normally insulating gases become electrical conductors when a high voltage is applied across them.
