Atoms and the Periodic Table
Dr Brian Cox takes us on a journey through the history of particle
physics. In this episode we learn that the Greeks knew about atoms and
how Mendeleyev's periodic table was among the first clues that the atom
had a deeper structure.
The Discovery of the Electron Transcript
Dr Brian Cox takes us on a journey through the history of particle physics. In this episode we learn how J.J. Thomson discovered the fist subatomic particle - the electron.
