Atomic Timeline

  • John Dalton

    John Dalton
    John Dalton was a chemist, physicist, and meteorologist. He is best known for proposing the modern atomic theory and for his research into colour blindness, sometimes referred to as Daltonism in his honour. He used crudely fashioned dew point hygrometer to determine how temperature impacts the level of atmospheric water vapor.
  • JJ Thomson

    JJ Thomson
    Joseph John Thomson was an English physicist and Nobel laureate in physics, credited with the discovery and identification of the electron; and with the discovery of the first subatomic particle. Although he assumed that the positive charge of an atom was all one uniform blob of matter with the electrons moving in orbits inside the nucleus.
  • Max Planck

    Max Planck
    Max Planck was a theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics. However he was equally convinced ,that the second law of thermodynamics is an absolute, as his peers
  • Neils Bohr

    Neils Bohr
    Niels Bohr was a physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics
  • James Chadwick

    James Chadwick
    Chadwick has had many papers published on the topic of radioactivity and connected problems and, with Lord Rutherford and C. D. Ellis, he is co-author of the book Radiations from Radioactive substances. He wrongly determined that only the proton was located in the nucleus and nothing else.
  • Ernest Rutherford

    Ernest Rutherford
    Ernest Rutherford is one of the most illustrious scientists of all time.He is to the atom what Darwin is to evolution, Newton to mechanics, Faraday to electricity and Einstein to relativity. His pathway from rural child to immortality is a fascinating one. He spoke only twice in the House of Lords, both times supporting of industrial research.
  • Lise Meitner

    Lise Meitner
    Lise Meitner was a physicist who worked on radioactivity and nuclear physics. She discovered the radiationless transition known as the Auger effect. In 1944, she was awarded the Nobel Prize for Chemistry for his research into fission, but was ignored. But her discovery came at exactly the wrong time, and her primary role in both the experimental and theoretical discovery of nuclear fission would never be properly awarded.
  • Grace Hopper

    Grace Hopper
    Grace Hopper was a computer scientist and United States Navy rear admiral. She invented the A-0 System. Admiral Hooper received many awards and commendations for her accomplishments and contributions.
  • George Zweig

    George Zweig
    George Zweig was a physicist. He was trained as a particle physicist under Richard Feynman. He introduced the quark model. He later turned his attention to neurobiology. He worked too much with quarks and didn't have time to do other types of research.
