Did you know?
In 1905, in the year that Theodore Callaghan was born, the German born physicist, Albert Einstein, proposed the Special Theory of Relativity: 1) that observers can never detect uniform motion except relative to other objects and that 2) unlike the velocity of massive objects, the speed of light is a constant and is the same for all observers independent of their constant velocity toward or away from the light source. Not such simple concepts that lead to the equation everyone now knows: E = mc2.
Did you know?
In 1920, at the age of only 15 years old, Theodore was alive when on November 2, radio station KDKA began broadcasting in Pittsburgh, PA. This was the first commercial radio broadcast in the United States. Westinghouse, a leading manufacturer of radios and the backer of the station, chose the date because of the Presidential election. People liked it because they could hear about the results of the election between Harding and Cox before the morning papers arrived. Four years later, there were 600 commercial stations broadcasting in the U.S.
