Did you know?
In 1898, in the year that John Dupczyk was born, on February 15th, the USS Maine exploded and sank in Havana harbor. The reason for the explosion has never been found, but it killed 266 men. "Remember the Maine" became a rallying cry and precipitated the United States' declaration of war on Spain two months later - the beginning of the Spanish-American War. On December 10th, the war ended with the signing of the Treaty of Paris. The Treaty gave the U.S. Puerto Rico, the Philippines, Guam - for $20 million - and, temporarily, Cuba.
Did you know?
In 1905, at the age of only 7 years old, John was alive when 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.
