Right now World War 1 is currently happening. Currently turning my attention to antisubmarine reasearch (underwater warfare).

UPDATE: 1919- I just disovered how to artificially induce a nuclear reaction in a stable element!

UPDATE: I hope my discovery of the #nuclearmodel diddnt pave the way to the #nuclear bomb.

UPDATE: 2 years after Rutherford's death: Disovery of nuclear fission, and resulted in what Rutherford had feared- the use of nuclear power to build wartime weapons.

Contributions

• First to split the atom
• Theory of atomic structure
• Disovered and named the atomic nucleus, proton, alpha particle, and the beta particle.
• Discovered the concept of nuclear half-lives and achieved the first deliberate transformation of onel element into another
• Discovery of atomic nucleus.

Education

My Atomic Model

• Awarded scholarship in 1887 to attend Nelson Collegiate School
• Awarded another scholarship in 1890 to attend Canterbury College in Christchurch, NZ
• Won scholarship to go to University of Cambrdige in the UK to work in J. J. Thompsons's lab in 1895.

I discovered the atom must have a small, dense, core from my #goldfoilexperiment, the #nucleus!! Notice how nearly the total mass of an atom is concentrated in the nucleus.

Fun Facts

• Encyclopædia Britannica considers him to be the greatest experimentalist since Michael Faraday.
• The element 'rutherfordium' was named in Rutherford’s honor.
• He was a direct, no-nonsense man, who spoke his mind. He was not overly concerned with his appearance; some people mistook him for a farmer!
• An unusually large number of his research workers went on to win Nobel Prizes, including James Chadwick, Cecil Powell, Niels Bohr, Otto Hahn, Frederick Soddy, John Cockcroft, Ernest Walton and Edward Appleton.
• In addition to his Nobel Prize, he was knighted in 1914, becoming Sir Ernest Rutherford, and then made a British lord, receiving the title Baron Rutherford of Nelson in 1931.
• Known for his booming voice

The experiment that helped me to establish the nuclear theory of the atom: When I shot a beam of a alpha particles (radiation from uranium) at a sheet of gold foil, a few of the particles were deflected. I concluded that a tiny, dense nucleus was causing the deflections. #atomictheory
