Thought for Today: 14-Feb-2018:
This is about a strange dream I had last night of the Metric Units for time and Angular Measures. Surprisingly, we have no Metric equivalent of these two units. Why can’t we have one for these two measures? Let’s examine:
Time and angular measures are very close, the time arises out of the rotation of earth. Years, fortnights and days are fixed. Only days of weeks and hours of days can be changed - say to Metric style. One week may have 10 days, which most will not like. But, a day may have 10 hours, an hour may have 100 minutes, a minute may have 100 seconds. Further down seconds we already have a metric system as milli-second, micro-second and so on. So now a day will have 10 Hours, 1,000 Minutes and 1,00,000 seconds instead of 24 Hours, 1,440 Minutes (1 Min = 0.6944 Metric Min) and 86,000 seconds (1 sec = 1.1628 Metric Sec).
Similarly, for Angular Measure, we may have 100 degrees a right angle, total 400 degrees. Every degree may have 100 minutes and every minute may have 100 seconds. Thus the earth rotates 0.40 metric degrees every metric minute instead of 0.25 degrees every minute. (1 deg = 1.11111 metric degree, 1 min = 1.85185 metric min and 1 sec = 3.08642 metric sec)
