Time zones
Today at the end of class, Mr. Schick brought up a really good topic. Why do we start our day at 12 o'clock? I've thought about this one night when I couldn't go to sleep. I then couldn't think of a reasonable answer. so I gave up. I looked up why there's 24 hours in a day and it said this, "Our 24-hour day comes from the ancient Egyptians who divided day-time into 10 hours they measured with devices such as shadow clocks, and added a twilight hour at the beginning and another one at the end of the day-time, says Lomb. " Night-time was divided in 12 hours, based on the observations of stars." As I looked more into this topic I found there's a more in depth explanation for the division of night-time into 12 hours which is based on the number of "decan" stars which were seen to rise during summer nights in Ancient Egypt. This made more sense to me, but I still ponder on why we always stuck with the 24 hour day. Then again we are still primarily using a map from 1569. I hope that the class of 2022 can be the class to help make more discoveries and possibly make a difference in the world.
