The title of this thread reminded me of a great little book called A History 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:

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

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.

https://www.youtube.com/watch?v=epCOGAa7tRQ


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.
"Still, doubts gnawed at everyone. And under no circumstances could I acknowledge my own similar doubts. In order to coax the participants into psychic stability, I had to appear to be rock-solidly convinced of the necessity of carrying out this horrifyingly cruel command."

Rudolf Höß, hanged facing Auschwitz, the camp he commanded, in April 1947. He admitted to 1.1 to 1.5 million murders carried out under his command. Eichmann told him the number was 2.5 million.

Very ambitious, once again. Pretty good job, though far too focused on the "great men" aspect of science. Well, what the hell CAN one do, given 12 minutes to talk about the origins of calculus? Many French mathematicians, to this day, regard Fermat as the true inventor of calculus. And Descartes also deserves a lot of credit, as does Pascal. Those three French guys produced a lot of results that Newton and Leibniz didn't have to discover for themselves. For that matter, Newton's teacher, Isaac Barrow, actually proved a theorem equivalent to the fundamental theorem of calculus. It's hard to recognize it because it was phrased geometrically rather than algebraically. The geometry needed to be algebraized (which Fermat and Descartes actually did) before it could be simplified. In particular, instead of the derivative f'(x) of a function, Barrow, Pascal, Descartes, and Fermat all worked with the subtangent, which for positive functions f(x) is the quotient f(x)/f'(x). But obviously, if you can compute the one, you can compute the other. Newton was grossly unfair to both Descartes and Leibniz. (Whose name, by the way, is pronounced as if it were LIBE-nitz, not LEEB-nitz, as in the video. This guy also badly butchers the pronunciation of Latin in a way that would provoke objections from both a Benedictine monk and an Oxford don.) As for Descartes,

Isaac Newton wrote: Descartes makes a great show [of his solution of the three-line and four-line locus problem], as if he had achieved something so earnestly sought after by the ancients...[whereas if this algebra were written out in words], if would prove to be so tedious and entangled as to provoke nausea.


I got a news flash for ya, Ike: (1) The three and four-line locus problem really was earnestly sought after by the ancients, and Descartes also showed how to solve the five- and six-line locus problems. (2) The whole point of being a mathematician is to develop a nice compact notation, as Descartes did, to simplify thinking and avoid tedium and nausea.

So, it's incomplete. Well, what can one expect in 12 minutes? I've foolishly allowed myself to get roped into an encyclopedia project for Bloomsbury Press in London, in which I'm supposed to write the history of Russian and Soviet mathematics from 1914 to 2000....in 5500 words! That's going to set a new standard for incompleteness. So, continue with the Crash Courses. They fulfill a valuable function, whereas my encyclopedia article, as they say, will fill a much-needed gap in the literature.
"Still, doubts gnawed at everyone. And under no circumstances could I acknowledge my own similar doubts. In order to coax the participants into psychic stability, I had to appear to be rock-solidly convinced of the necessity of carrying out this horrifyingly cruel command."

Rudolf Höß, hanged facing Auschwitz, the camp he commanded, in April 1947. He admitted to 1.1 to 1.5 million murders carried out under his command. Eichmann told him the number was 2.5 million.
