In 1900, in the year that Mary Duncan was born, the German physicist Max Planck formulated an energy theory, postulating the existence of "quanta," which lays the groundwork for the quantum theory of modern physics. In December, he introduced a paper on the Planck postulate which stated that E=hv - the energy of a photon is proportional to its frequency times a constant. Planck won a Nobel Prize in 1918 for his work in theoretical Physics.
Did you know?
In 1912, when she was just 12 years old, in October, former President Theodore Roosevelt was shot, but not killed, while campaigning for another term as President with the newly created Bull Moose (Progressive) Party. John Schrank was a Bavarian-born saloon-keeper from New York who had been stalking Roosevelt when he shot him just before a campaign speech. Shot in the chest (and showing the audience his bloody shirt), Roosevelt went on to give a 55 to 90 minute talk (reports vary on the length) before being treated for the injury. After 8 days in the hospital, Roosevelt went back on the campaign trail.
