jan 1, 1902 - Ernest Rutherford
Description:
Ernest Rutherford published his theory of radioactive decay in the Philosophical Magazine. He discovered that radioactive material decayed according to an exponential law and created the concept of half-life. Rutherford also proved that atoms of one radioactive element would spontaneously turn into another, by expelling a piece of the atom at high velocity.Added to timeline:
