For example, the first method invented to detect individual nuclear particles by electrical means, the Rutherford-Geiger detector, evolved into the Geiger-Muller tube.

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.Had it not been for that war James and Martha would never have met.Martha became a teacher at the Spring Grove school where her efforts were always praised by the provincial school inspector.So Ernest Rutherford and his siblings received a good education because of parents who appreciated education: his father because he hadn't had much and his mother because she had..Family chores, such as milking cows and gathering firewood, ate up time after school.As a boy Ernest was surrounded by hard-working people with technical skills. and arrived in New Plymouth in 1855 as a thirteen-year old.

She was evacuated to Nelson in 1860 during the Taranaki Land War.Encouraged by Sir Robert Ball, who wished to solve the difficult problem that a ship could not detect a lighthouse in fog, and sensing fame and fortune, Rutherford increased the sensitivity of his apparatus until, in February of 1896, he could detect electromagnetic waves over a distance of several hundred metres, a then world record. Thomson invited him to join in a study of the electrical conduction of gases.Wireless telegraphy was thus left for Guglielmo Marconi to develop and commercialize.He radically altered our understanding of nature on three separate occasions.Through brilliantly conceived experiments, and with special insight, he explained the perplexing problem of radioactivity as the spontaneous disintegration of atoms (they were not necessarily stable entities as had been assumed since the time of the ancient Greeks), he determined the structure of the atom and he was the world's first successful alchemist (he converted nitrogen into oxygen).The cannon exploded, luckily without causing injury.
