He discovered two different types of radiation, which he named alpha and beta.

He devised a method of dating rocks relating their age to the amount of helium present in them.

Based on the fact that our planet is still volcanically active, Lord Kelvin had indicated Earth’s age could be no greater than 400 million years old.

And so in 1898 Rutherford sailed to Canada, taking up a professorship, aged just 27.

At Mc Gill he carried out the work which led to his 1908 Nobel Prize in Chemistry. Thomson’s retirement as the Cavendish Professor of Experimental Physics at the University of Cambridge.

At the age of 18 he left for the city of Christchurch, where he had won a scholarship to Canterbury College, now the University of Canterbury.

In 1893 he graduated with first class honors in both mathematics and physical science.

Geiger and Marsden used a sample of radium to provide a stream of alpha particles, which passed through the gold foil.

Where the alpha particles ended up was recorded electrically. If gold were a smooth substance on the atomic scale, as it had been thought to be, a slight deflection of alpha particles would have been expected.

In 1895 he obtained a bachelors degree in chemistry and geology from Canterbury College and went on to spend a short time working as a schoolteacher. Rutherford had already invented a radio receiver in New Zealand; he improved it at Cambridge, where he built a world-record-breaking receiver capable of detecting radio waves at half-a-mile.

He then won a scholarship enabling him to study overseas. Rutherford arrived in Cambridge in 1895 and the 24-year-old newcomer was made to feel very welcome by J. However, the battle to develop radio was one he would quickly lose to Guglielmo Marconi. His radio work was not as intellectually stimulating as other work he was doing at Cambridge on radioactivity and the effects of X-rays on gases.

His father, James Rutherford, was a farmer from Scotland and his mother, Martha Thompson, was a schoolteacher from England.
