  • Max Planck

    Max Planck
    Max Planck was born on April 23, 1858 and died on October 4, 1947. During the twentieth century, Max Planck was a highly important physicist. He claims to be the establisher of the quantum theory. The quantum theory is the theory that matter is made up of atoms. Max Planck was awarded the Noble Prize in Physics in 1918 for his astonishing discovery.
  • Ernest Rutherford

    Ernest Rutherford
    Ernest Rutherford was born August 30, 1871 and died October 19, 1937. Rutherford was a British-New Zealand chemist and physicist. He discovered the half life of radioactive substances and that radiation can be classified as alpha and beta. Rutherford was awarded the Noble Prize in Chemistry in 1908 for his studies in elements and radioactivity. In 1911, Rutherford figured out that atoms contain their positive charge in the nucleus. In 1917, he conducted the very first splitting of an atom.
  • Albert Einstein

    Albert Einstein
    Albert Einstein was born on March 14, 1879 and died on April 18, 1955. Einstein was a theoretical physiscist, philosopher, an author, and one of the most well known scientists in history. Einstein received the 1921 Nobel Prize in Physics for his contribution to Theoretical Physics and discovery of the law of the photoelectric effect. Einstein theorized that the energy in each quantum of light was equal to the frequency multiplied by a constant.
  • Max Born

    Max Born
    Max Born was born on December 11, 1882 and died January 5, 1970. He was a German physicist who made many contrubutions to physics. Born was awarded the Noble Prize in Physics in 1954. He formulated the probability density function for ψ*ψ in the Schrödinger equation. As well as, he contributed to solid-state physics and optics.
  • Niels Henrik David Bohr

    Niels Henrik David Bohr
    Niels Henrik David Bohr was born on October 7, 1885 and died November 18, 1962. Bohr was a Danish physicist who contributed to quantum mechanics and atomic structure. He was awarded the Noble Prize in Physics in 1922 for his discovery of the structure of atoms and the radiation emanating from them. Bohr was a part of the physicists working on the Manhattan Project, which occured during World War ll to create the 1st atomic bomb.
  • Erwin Rudolf Josef Alexander Schrödinger

    Erwin Rudolf Josef Alexander Schrödinger
    Erwin Rudolf Josef Alexander Schrödinger was born August 12, 1887 and died January 4, 1961. He was an Austrian theoretical physicist. Schrödinger was awarded the Noble Prize in Physics in 1933 for contributing may things to physics, but most importantly developing the Schrödinger equation which shows how the quantum state of a physical system changes in time.
  • James Chadwick and E.S. Bieler

    James Chadwick and E.S. Bieler
    James Chadwick was born October 20, 1891 and died July 24, 1974. Chadwick was an English Nobel laureate in physics. He was awarded the Noble Prize in Physics in 1935 for the discovery of the neutron. The neutron is a neutrally charged particle located in an atom's nucleus. The discovery of the neutron served as an important factor in the fission of uranium 235, and creating elements heavier than uranium. E.S. Bieler concluded with Chadwick that a strong force held the nucleus together.
  • Louis de Broglie

    Louis de Broglie
    Louis de Broglie was born August 15, 1892 and was born March 19, 1987. He was a French physicist, a Nobel laureate, and the 16th member in 1944 elected to be in the Académie française. Broglie's 1924 doctoral thesis stated his theory of electron waves. This opened a new area in physics called, wave mechanics. Wave mechanics combined the physics of energy and matter. He won the Nobel Prize in Physics in 1929 for his work on wave mechanics.
  • Werner Heisenberg

    Werner Heisenberg
    Werner Heisenberg was born December 5, 1901 and died February 1, 1976. Heisenberg was a German theoretical physicist and is known for theorizing the uncertainty principle of quantum theory. The uncertainty principle states states by precise inequalities that certain pairs of physical properties can't be simultaneously known to arbitrarily high precision. Heisenberg also worked on nuclear physics, quantum field theory and particle physics. He was awarded the Noble Prize in Physics in 1932.
