The title of this thread reminded me of a great little book called A History of Pi.
https://www.amazon.com/History-Pi-Petr- ... tory+of+pi

I haven't read it in years and just ordered a used copy from Amazon.

I can almost guarantee that anyone here who hasn't read it will love it.

I missed two episodes, either while I was away or while youtube was ignoring me and not telling me when new videos had been posted (or, alternately, telling me that someone had posted four, five, or even seven new videos when they had no new videos to see on their channels).

So here is episode #2:

If they don't start with, "Have you tried poking it with a stick?" I'm not interested.

That's skipping ahead a few million years. Have you tried smashing it with a rock? Maybe banging two together to make a spark?

I only make sparks by accident, like when I knock my friend off a moving car and his teeth hit the pavement at 30 mph.

Woah... That brings back a childhood memory...

Me and some friends were out playing late. It was dusk. Almost dinner time. I was maybe 8. But we found this weird rock. It was white, and crystalline. There were a bunch of other bits of it lying about. I picked up a bit and hit it. Not only did an orange spark fly off, but the crystal glowed blue. I said, go get your dad's hammer.

And then we smashed it to bits. There were many sparks.

One time I fell off the roof of another friend's car, and almost saved my beer. I have the scar to prove it.

OK. This one caught my eye.

I've closely studied women my entire life. My observation is that they're everywhere. My method is a trade secret. In conclusion, more study is required.

Not bad as a popularization. The guy has a good delivery, and of course, you can't go into much detail in 12 minutes, so some appearance of inaccuracy is inevitable. He says that these guys had students who made copies of what they wrote down. Maybe so, but most of what we know about the pre-Socratics comes from quotations of documents that no longer exist, especially by Aristotle, who usually quotes only to refute. Our knowledge of the social history of the Pythagoreans is pretty much based on Plutarch and Aulus Gellius ("Attic Nights"), and these guys were as remote from Pythagoras as we are from Petrarch. The most comprehensive ancient history of science, allegedly a copy of a work by Aristotle's student Eudemus, of which the original no longer exists, comes from more than a thousand years after Pythagoras. Who can say how accurate these versions are? The only physical documents still extant are from a garbage dump in Oxyrhyncus, Egypt, and they are only a few fragments. (A famous one gives a theorem from Book II of Euclid, showing geometrically how to do what is called completing the square in algebra.)

About 50 years ago, a German scholar whose name escapes me at the moment did a complete study of every quotation from Pythagoras that seemed to be authentic, and concluded that the Pythagoreans really had no scientific interests at all, to speak of. Their interests, according to him, ran much more in the direction of Buddha and his followers. Maybe so, but then why did Plutarch and Gellius go into such detail about the scientific interests? Plutarch even quotes a couple of theorems he says are due to Pythagoras, and Gellius gives a detailed discussion of the sociology of the Pythagorean cult. Initiates were first called "akoustikoi" (auditors), then progressed to become "mathematikoi" (learners---mathein is the aorist infinitive of the verb meaning to learn) and finally "physikoi" (natural philosophers---physos means inborn or innate). The "-ik-" in each of these should be interpreted as "skilled at". So, at least, Gellius claims. Most historians of mathematics (notably Jeremy Gray and Wilbur Knorr) don't think the discovery of incommensurable pairs of lines (neither of which can be assigned any rational number as its length using the other as a unit) goes back to the Pythagoreans. They think it was made in Plato's school, and that it was not regarded as any big deal.

There is a small inconsistency in that he pronounces Empedocles approximately the way it sounded in Greek, while most anglophones put the stress on the -ped-, just as with Thucydides, although the Greek pronunciation is more like "two-cue-DEED-ace". On the other hand, he gives Thales the anglophone pronunciation, while the Greek sounds approximately like "tall-ACE". Well, that's OK. Pretty good job in general.
