Zeno never had children. So, how could he tell his grand-children these paradoxes?

Ah a classic, “I’m not touching you”

Zeno’s tortoise paradox. The original idea was, you’re racing a tortoise. We’ll call him Marcus. Marcus has a ten yard head start. In the time it takes you to run ten yards, Marcus has moved maybe two yards. In the time it takes you to run two yards, Marcus has moved a little more. You run that smaller distance and he moves a little more. You could run forever, and never catch Marcus, you’d just decrease his lead. Of course you can just run past the tortoise in real life, but Zeno didn’t understand how that could happen. The truth is simple though- eventually the tortoise’s lead is smaller than one of your steps. That step will take you past him before he moves further. Then the tortoise is moving slower than you and is behind you, so you could win that race.

Miles, you created not a best friend, but a monster.

The principle of infinite regression. You can never cross the road. You must first cross half the road, then half of the half, then half of the quarter, then half of the eighth… Rejection of the idea is why the Greeks invented the atom. (You can’t keep dividing something in half forever. At some point there is the smallest indivisible particle, an atom – which is absolutely solid and can not be divided/split. The solid atom was an article of faith for centuries and may have held back modern physics. But, hey, most of the Theistic Proofs of Aquinas depend on the rejection of infinite regression.)

Wow. Nice to see some so smart and well educated actually reads one of the better comics! Thanks for the education!

Kevin…always putting valuable new learning to practical use. Gotta love him

My physics professor (Dr. Yount) described it thusly… If Bob and Carol start out twenty feet apart, halving the distance between them every minute, then they will never actually meet. But they’ll be close enough for all practical purposes (eyebrow waggle).

Miles finally got his hair back! Hooray!

Who doesn’t do that to their siblings?

Well, I cant say I’ve never done this

Miles’ hair is really growing fast- yesterday it was still close to his scalp and I thought it would stay that way for while – guess not!

Love how Miles has a philosophical musing and Kevin uses it for his own nefarious purpose

This principle has been known and practiced by adolescent children since the beginning of time.

Miles’s hair grew back.

His hair grew back really fast!

I’m glad to see one of our favorite games, “I’m not touching you,” has stood the test of time.
