What is this tower and why have I used it against this post?

Have you ever given that any thought? English, especially with the Web, definitely feels like the lingua franca of the day. [By the way, what does lingua franca mean?] So is English the predominant language in the World. It is worth thinking about.


Think first, then research, then THINK again. Think for the pleasure of thinking.


Yesterday’s ‘Think’: “24 hours in a day” — the ancient Egyptians came up with this. We know that because we have been able to find sundials testifying to this. They split the day into 10 DAYLIGHT hours. Then added a TWILIGHT hour at each end to get 12. Then 12 hours of darkness. The 12 hours was because the Egyptians didn’t count (to 10) using the fingers of their hands! Instead they counted using the JOINTS in the four, non-thumb fingers of a hand. Each non-thumb finger has 3 joints. Have a look. 4 fingers, each with 3 joints = 12. Easier to count. You can count using the forefinger (index finger) of one hand … Plus 12 has more divisors than 10. In other words 12 can be divided by (1), 2, 3, 4 & 6. That helps when trying to divvy up things. Ten, on the other hand, is only divisible by (1), 2 & 5. Not as handy.

Think – Today: Why Do We Have A 24-Hour Day?

sundialWhy 24? Why wasn’t it 20? Have you ever wondered? Pretty important to our lives. Most of us are slaves to time, but we are so busy that we never get a chance to think as to how time, as we know it, came to be.

Yesterday’s ‘Think’: “Changes in the composition of the atmosphere” — 99% of our current atmosphere is made up of two gases: Nitrogen (78%) & Oxygen (21%). All the other gases, including the Carbon Dioxide (that gets talked about so much in the context of climate change), fall within the remaining 1%! Carbon Dioxide, right now, only accounts for about 0.037%. As far as scientists have been able to determine, this 99% Nitrogen/Oxygen composition, possibly with some ‘small’ variations, has been around for the last 200 million years! WOW. In the ‘early days’ and we are talking maybe a billion years ago there was much more Carbon Dioxide and considerably less oxygen. Photosynthesis by plants, where they absorb Carbon Dioxide and release oxygen, was a factor in changing the composition of the atmosphere.
