## Any Old Pi Will Do

Make a joyful noise for today, oh happy day, is Pi Day, 3/14. As you surely know by now, either because you remember some maths or because you don’t live in in the wild, 3.14 are the first few digits of π. And, as we know, Pi are squared. Although, as my 8th grade math teacher Louise Blanchfield told us with a mischievous old-lady I’ve-been-telling-this-joke-for-forty-years grin, “Pi are not squared, Pi are round.” Meanwhile, I am proud to say that the establishment of this august day of celebration first occurred in my neck of woods, a day recognized by Larry Shaw at the San Francisco Exploratorium back in 1988. The rest is a lot of fun history.

## Achtung Lieber! It’s a Miracle!

One particularly curious fact about Pi Day is that it also happens to be Albert Einstein’s birthday. He didn’t have anything to say about pi, pier se (see what I did there? that’s not the last pun I am about to inflict on you either)… anyway, Einstein wasn’t a geometer, but he was a brainy guy and did a lot of math. Actually he failed math, which is always used as an example of how you could buckle down and make something of yourself even if you start a failure.

However, I always thought it was a better example of how to successfully buck the establishment, since it’s likely that Einstein failed math because he kept telling the teachers they were wrong. And they were. It’s more like Stephen Hawking crumpling up his physics homework and throwing it in the trash because he didn’t think his proofs were elegant enough. Other students would get them out of the trash so they could understand how to do physics.

RIP Stephen Hawking–who coincidentally passed away yesterday–or maybe it was today since it’s 12 hours ahead in Cambridge. (And you know those smart people always want to be ahead of everybody else.) Stephen and Albert can now argue about the exact shape of the curvature of space-time until infinity or until the end of pi. Maybe they can borrow some of Newton’s apples to use for examples.

## Where Fancy is Bred

Where, oh where, is fancy bred?
In the heart or in the head?
–Shakespeare, Merchant of Venice

The heart is a powerful muscle, delivering nourishment and energy throughout the body, second by second and minute by minute. The sound of a heartbeat signifies life, fear, elation, and anxiety – the approach of a leopard and the approach of a beloved. One of the most joyous sounds is of a heartbeat in a mother’s womb; the joyous picture is the sonogram of that beating heart. The heart has been described since ancient times as the seat of emotions, though 20th century scientists in the age of “better” information designated the brain as the true ruler of emotions rather than the heart. How did the ancients get it wrong? Or did they?

Blame it on Aristotle. Blame it on the Catholic and the Lutheran Church. Blame it on the Cro-Magnons.

For Valentine’s Day, I set out to find out where the scalloped heart shape came from and why the heart was identified as the seat of emotion. As with all investigation into historical and scientific evidence, the answer is … complicated. Continue reading “Where Fancy is Bred”
