Deep thoughts

I recently read that cognitive function increases during endurance exercise. Or in other words, riding a bike makes you smarter. At least for as long as you're riding the bike. This may explain why I often find myself thinking during a ride about things that are so out there that they surprise even me. Some of them are laughable, most of them forgettable, and a few are just so bizarre that I'm really not sure where they come from.

For instance, while I was riding yesterday, I started thinking about the difference between 26" and 29" wheels on a mountain bike. Which led me to think about the relationships between the wheel sizes, specifically calling to mind that pi is the ratio of a circle's diameter to its circumference. I then began to ponder pi and found myself wondering if there were some other world with its own unique system of mathematics where pi is an integer.

Like I said, not sure where that one came from or whether it proves an increase in cognitive function or just the opposite. But I do like pi.

What did you think I meant?

  1. The book / movie "Contact" clears up that whole meaning of pi issue.

    I find myself lost in thought a lot on the bike. Sadly, it's usually a song phrase or stanza that keeps repeating over and over.
