One benefit of base 12 and base 60 over base 10 for everyday use with things like time is simple factorization. You can divide 12 hours evenly into halves, thirds, quarters, and sixths, and 60 minutes evenly into halves, thirds, quarters, fifths, sixths, tenths, etc. With base 10, youโve just got halves and fifths.
Another benefit of base 12 is that you can count to 12 easily with one hand by using your thumb to count each of the 3 segments on your 4 fingers.
I learned that on that other website prior to the great migration and it blew my mind then.
Pros scale that up to base 60 by counting to 12 and using the other hand to count how many times they have counted to 12.
Thems rookie numbers. You can get to 144 using the twelve segments on each hand.
Iโm trying to think of a situation where I need to count to 12 on one hand ๐ค
This would be useful if I was used to counting with base 12.
Yeah, I know all about that, but I donโt think weโll convince people to change everything to base 12, so letโs go with a base 10 clock.
A base-10 unit circle would be abhorrent. 1/2 of a circle is an important concept, but 1/5th and 1/10th of a circle are rarely used in geometry or trigonometry. Meanwhile, a right angle (1/4 of a circle) would require an ugly fraction, and the angle of an equilateral triangle (1/6th) would require a repeating decimal.
Think of 12-hour clocks and 360-degree circles as paper bags. When weโre fucking with angular concepts, you do not want to take those bags off Decimalโs head.
I just want everything to be switched to 24 instead of 12. Why everyone want to complicate things?
I didnโt put in a secret punchline. Itโs a genuine thought. What do you think I did?
