Sir James Chadwick (1891-1974) was an English physicist and winner of the 1935 Nobel Prize in Physics. James Chadwick began his academic studies at the University of Manchester under the tutelage of Ernest Rutherford. Here, he earned his B.S. in 1911 and his MSc in 1913. WebJun 19, 2024 · James Chadwick created radiation from a radioactive Beryllium isotope and aimed this at Paraffin wax, a large hydrocarbon. Chadwick then measured the range of the protons that were given off and he found that instead of gamma waves being produced that a particle of the same mass as a proton but uncharged had been produced. mall chino rojas magallanes
