Did you know?
In 1900, in the year that Mary Lenkner 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 1910, Mary was only 10 years old when Halley's comet, which returns past the earth every 75 - 76 years was observed photographically for the first time. Two fortuitous events occurred - photography had been invented since the last time the comet had passed and the comet was relatively close. There was panic because one astronomer claimed that the gas from its tail "would impregnate the atmosphere and possibly snuff out all life on the planet." People bought gas masks, "anti-comet pills" and "anti-comet umbrellas".
