What’s the best way to memorize the digits of pi?

**Calvin Trillin**explores the options, including using music, a form of poetry known as piems, and clustering the numbers. “

**Lu Chao**, the official world-record holder, used a method he based in part on the Chinese language—one that enabled him to recite sixty-seven thousand eight hundred and ninety digits,” writes Trillin. Even high-schoolers are tackling the challenge, particularly high-schoolers at New York City’s Facing History School, which awards the student with the best pi memory an iPod Touch during Pi Week. This year’s winner: a sophomore named

**Jason Gil**, who recited 162 digits.

Don’t bother. Learn Tau instead.

The question is why?

Everyone should stop using Pi and start using Tau, it makes way more sense. And it would give people who are bad at memorizing things a chance to hold the world record (at least for a day or two).

Memorizing the digits of pi, like the number itself, is irrational.

It’s sad that a school is rewarding such useless efforts. Memorize useful theorems or formulae, or memorize random phone numbers from the phone book; any of those would be more useful than memorizing the digits of pi. You’re not going to beat your calculator.

Yes, use music.

Interesting, and I’m sure there are some positive consequences of going through the exercise to some extent, but surely the extreme exercise is a whopping waste of time and effort. It’s just a form of trivia.

But I could be persuaded otherwise, I suppose. Convince me.

Furthering the discussion of memorizing the digits of pi: Pi is irrational, an infinite string of numbers so any finite string of numbers you can recite, read or just make up will be, somewhere, digits of pi.
