You are all familiar with the famous equation E=mc^2. If you drop the temperature of the calculator, you lower its energy, E. But you haven't affected its mass, m. So light must be travelling more slowly. At the colder temperatures, the speed of light, c, is affected such that time slows down. The result is that things in the cold environment SEEM to run more quickly to a warm-blooded observer. Hence the lesser- known Eskimo Pie Twin Paradox: Two twins are each given an Eskimo Pie ice cream bar to eat. One sits in a large refrigerated room at 10 C, while the other is placed on a warm beach at 40 C. Because of the quantum mechanical effects of time and the speed of light, it will appear to the first twin that he has lots of time to eat his Eskimo Pie before it melts, while the other twin at the beach APPEARS to have to eat more quickly. This phenomenon also explains why bears hibernate, and why children drowned in cold water can survive under water for unusual lengths of "time." Good Day!

If you disagree with my examples or theoretical reasoning, that only proves the fact that much of quantum physics is still classified by the US Government. You err because you don't have access to the right documents.
