1949 ENIAC computer,Anders Celsius

1. A chip of silicon a quarter-inch square has the capacity of the original 1949 ENIAC computer, which occupied a city block.
2. An ordinary TNT bomb involves atomic reaction, and could be called an atomic bomb. What we call an A-bomb involves nuclear reactions and should be called a nuclear bomb.
3. At a glance, the Celsius scale makes more sense than the Fahrenheit scale for temperature measuring. But its creator, Anders Celsius, was an oddball scientist. When he first developed his scale, he made freezing 100 degrees and boiling 0 degrees, or upside down. No one dared point this out to him, so fellow scientists waited until Celsius died to change the scale.
4. Since the Earth is also several million miles closer to the sun at that time of the year than in the summer, sunlight striking the moon was about 7% stronger making it brighter. Also, this was the closest perigee of the Moon of the year since the moon's orbit is constantly deforming. In places where the weather was clear and there was a snow cover, even car headlights were superfluous.
5. The first full moon to occur on the winter solstice, Dec. 22, commonly called the first day of winter, happened in 1999. Since a full moon on the winter solstice occurred in conjunction with a lunar perigee (point in the moon's orbit that is closest to Earth), the moon appeared about 14% larger than it does at apogee (the point in it's elliptical orbit that is farthest from the Earth).
