Tom Apostol was also part of the team that put together "The Mechanical Universe", a highly acclaimed 52 episode series of video lectures that cover a full undergraduate physics course.

The creators of the program provide all episodes online at https://www.learner.org/resources/series42.html

I never met the man but I learned a lot from him. May he rest in peace.

That site says: “After June 30, 2016, we will no longer distribute this series on DVD, and the videos will no longer be available online.” Anyone know why, or if they plan to do anything else with the videos?

An explanation is given here: http://scaapt.org/archives/1286

> "You may ask why the series is being retired. The original producers (Intelecom) do not have the staff or the information available to locate all the third party rights holders of the additional footage and rights to that footage has expired. Therefore, it must be taken out of distribution."

I imagine that unless unknown rights-holders pull them off YouTube (as they apparently haven't yet...) then it will still be available some places.

The above page also notes the availability of https://www.learner.org/courses/physics/ which includes 11 videos.

Our intellectual property system gets in the way again. Why don't all the limited government, anti-regulatory people complain about this?

There is a film of a way up, over the top lecture in plane geometry by Andrew Gleason with Tom Apostol.

I saw it broadcast late one night on a PBS station and intended for recording for playing in high school classrooms.

Elegant. Powerful. Nothing like what see in common high school plane geometry texts. I got in a few minutes after the start and recognized a lion by his paw. If you liked plane geometry, then you will be in love with this lecture.

I just did a Google search looking for a copy on YouTube and found nothing.

Anyone know where that lecture is?

One of my favorite books, I worked to buy used long after it was out of print, is

Tom M. Apostol, Mathematical Analysis: A Modern Approach to Advanced Calculus, Addison-Wesley, Reading, Massachusetts, 1957.

And that is advanced calculus more like your ugrad physics prof will see it. Great to have when studying Rudin, exterior algebra but having to study material much like physicists did it 100 years ago.

I learned analytic number theory from his text book. Probably unlike most other HN participants, that is where I learned big-oh notation, in its original context: measuring the growth of arithmetic functions. I distilled what I learned into a short little undergrad paper:

Thank you, Tom Apostol, for writing a book on analytic number theory for me to learn from.

I also learned the big-oh notation there. Among many, many other things. Absolutely great book.

Me three.

Absolutely, great introduction to analytic number theory for anyone curious about the subject.

I learned about Apostol's death from a post by a very astute mathematical biologist, Lior Pachter, who was once a student of Apostol's. The post is "The Ice Cream Cone Proof,"[1] which nicely illustrates Apostol's brilliance as a teacher.

I'm sad; I had him for the same course Pachter describes. One time he lectured on the prime number theorem, just for entertainment: he didn't prove it, but got deep enough to rather blow me away.

Here's a more recent elementary talk of his: http://www.its.caltech.edu/~mamikon/VisualCalc.html

Apostol's calculus texts were my first experience with 'real' proof-based mathematics, and I also learned real analysis through his Mathematical Analysis book. Good times; his books taught me a lot.

He wrote with clarity and conciseness; when I read Apostol it always seemed like not a single word was added unnecessarily. I highly suggest picking up his books, and am sad to see that he passed away.

If there is a Math's Heaven with the Book in it, I hope he joins the chorus.

(*) The Book as the place were the greatest theorems and proofs are located, P. Erdos, exposed in Noga Alon the probabilistic method.

By the way, there is a comment by someone nhatcher, is it the famous topology author?

Tom Apostol was my freshman math prof. He made math a useful tool for me. He was a great teacher. Thanks so much, Tom.

I only saw Apostle smile once. It was Gauss' birthday, which he always celebrated in April with a cake. It had the Flux Theorem (Divergence to Surface Integral), and I got the "dx" labeled piece.

I complained that he had given me the smallest piece, and saw just the hint of a curl to his lips.

Hopefully, the "useful theorem"* didn't die with him...

*Apostle always referred to the useful theorem when proving problems in class... if you could figure it out, you were done.

Check out page 212, 1969 Big T (lower photo). Big smile. But yeah, didn't see that very often. Upper photo of him on that page is amusing also.

I am tempted to believe that Lloydies had something to do with that 8^O...

We live for those we love and die.

That's actually a really cool link. Lots of photos of prominent CalTechers like Feynman and Gell-Mann that I haven't seen before (along with some of the former's artwork.)

I love the photo on page 219 of the engineering prof with his shiny new Tektronix 453 oscilloscope, which would have been exotic as hell back then. It's hard not to laugh at the idea of lighting up a smoke in a lab today.

I picked up his calculus book for the first time almost 15 years ago and still remember so much about it. Integration explained before derivatives, the method of exhaustion at the start, and that early (first?) exercise about "a number less than arbitrary epsilon therefore it's 0" all stuck with me through the end of grad school and to today.

Wow! I didn't know he was alive until recently. I used his books in high school extensively when preparing for my IIT entrance exam back in India. May he rest in peace.

Same here, didn't know! My father (a maths professor) showed me Apostol's books on calculus, always recommends them very much. May the earth be light on him.

My freshman & sophomore calc classes used his books 1 and 2. I still have them.

...and, quite remarkably for a calculus textbook that is still in use at many schools ~40 years later, the editions you and I bought at Caltech in the late '70s are the same editions that are used today. Volume I, second edition, 1967, and Volume II, second edition, 1969.

I wonder if there are any families where a parent went to such a school and bought these, and then their child went to such a school and used their parent's copies, and then their child did the same?

I was amazed to find those 2 books going for about $250 each on Amazon. Pretty good for 50 year old textbooks!

I bought mine used for maybe $5 each from some foolish upperclassman who thought he was done with calculus.

I now strongly regret having sold mine; the brief moment of glee and small amount of cash was small potatoes compared to the number of times I've since wanted to re-read them.

(Also glee-killing: AMa 95)

Off-topic, but am curious: was there a "standard" text for AMa 95? I didn't go to Caltech, but heard a bit about the course from a friend who did. These days I sometimes teach our equivalent course, and am always looking for good resources. Thanks!

They sold the paperbound lecture notes at the Caltech bookstore and presumably nowhere else (at least back in the 80s).

Ah, I see. Thanks for the info!

If bought as an investment in my freshmen year, and sold today, those books would have given an annualized return of around 8%.

I very rarely need calculus in my work, and so over time tend to forget an embarrassing amount of it. Three or four times I've decided to remedy this by rereading these books (although once, for variety, I used Spivak instead of Apostol). Of course, I always end up forgetting again.

The latest time I did this I tried to burn it in deeper by doing every exercise from Volume I, and every calculus exercise from Volume II. I probably should have kept my solutions and put them on the net. They might have been useful for people who are using these books for self-study.

My originals from the late '70s have physically not held up well. Loose pages, and the cover pulling away from the spine, and stuff like that.

There is an international paperback edition. The publisher does not sell it in the US, but numerous independent booksellers outside the US will sell and ship to the US, and several independent booksellers in the US import it. Same content as the US hardback, just thinner, a bit coarser, paper.

The US booksellers selling the imports typically sell them for about $18 per volume (including shipping). You can shave a couple dollars off that buying from an Indian seller, but personally I'd rather pay a little more to avoid a credit card transaction with someone who is under a completely different legal system just in case something goes wrong.

abebooks.com and biblio.com are good places to go for this kind of thing.
