In 1899, in the year that John C Blackwell was born, the meaning of Chinese "oracle bones" was rediscovered. Farmers in China had been turning up the bones in their fields for generations but most often they were ground up and sold as medicine. The chancellor of the Imperial Academy and a friend noticed, before they ground the bones, that they had writing. The bones had been used around the second millennium BC for divination.

In 1900, at the age of just 1 year old, John was alive when 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.
