I’ve been teaching my sons how to tell time on an analog clock. The following is a recent conversation:

Me: The little hand is the hour hand, and the big hand is the minute hand.
Eli: What’s the third hand for?
Me: That’s the second hand.
Alex: Why is the third hand called the second hand?

I had no idea how to respond.Fibonacci Clock

Here are some questions that I’ve been asked recently for which I did know to respond…

How good are you at algebra?
Vary able.

Why is simplifying a fraction like powdering your nose?
It improves appearance without changing the value.

What do you get when you cross geometry with McDonald’s?
A plane cheeseburger.

    I’m guessing that they’re called seconds because they are the second iteration of dividing hours (or degrees, in the case of angle measure) into groups of 60. The second “decimal” place in base 60.

    That said, I’ve never seen anyone go to thirds; we seem to use decimal fractions of seconds.

    So why aren’t minutes called “firsts”?

    If the third hand is the second hand, can we say by substitution that the third hand is minutes, too? But if the third hand is minutes, than the second hand doesn’t exist? Doesn’t that mean analog clocks are really only good for telling which hour of the day it is?
