Here are 34 lectures for his Linear Algebra course he recorded in 1999: https://ocw.mit.edu/courses/18-06-linear-algebra-spring-2010...

Along with Jacques Pepin's "deboning a chicken" .FLV video, these are among the greatest videos on the Internet.

Great comparison! Both are absolute treasures.

Thanks to his recorded lectures I finally passed LA in a dutch University. At the time ~2008 my university profs had a say for specific courses if they wanted it recorded or not. Of course the profs who refused were gray dinosaurs. I'm glad Gilbert didn't fall into this education conservatism.

Linear Algebra was a course in the first semester of freshman year when I was in uni (this wasn't in the US or in an english speaking country). It was famous for being a "filter" course, that made a lot of people quit the degree and switch to a different degree next year. It had a 94% failure rate, but I got to pass on the first attempt because Gil's free lectures of his LA course made me intuitively understand the s…

I had the same experience. I didn't understand the teaching from my university. Once I found his lectures it all clicked. I understood what we were doing. It was no longer wrote learning of algorithms to manipulate things with no meaning. I did very well in that paper.

Fwiw the word is “rote” not “wrote”

I took linear algebra about 20 years ago as a requirement for my CS degree. I had no clue whatsoever what it was for beyond just "solving systems of equations" - whatever that meant. The prof didn't impress upon us how it underpins all of machine learning (which, mind you, wasn't as much of a hot topic then that it is now). Our attempts at grokking its importance were largely met with a kind of "because it's importan…

Same thing happened to me. Yes ml wasn't a hot area then (20 years ago) but computer graphics, linear regression (ie old school statistics used for supply chain), signal processing for audio and video were all got them but their applicability was never pointed out let alone emphasized. I was just lucky that I was interested in these areas on my own so the linkages thankfully "clicked". Is it me or did profs back then just do research and teaching in a bubble?

TIL, thank you.

Amazon printing service? I see they have one for photos/calendar and such. Do they have one for sending PDF's to print?

omg https://kdp.amazon.com/en_US/help/topic/G201834340 ah crap no pdf

I think, that is the Amazon service I have used to print out the book. I uploaded the pdf and week later got the book from Amazon. I will go though email and will get back to you.

There is a great book published in Russian "ЗАДАЧИ И ТЕОРЕМЫ ЛИНЕЙНОЙ АЛГЕБРЫ" (Problems and theorems in linear algebra), by Victor V. Prasolov. English translation was done by American Mathematical Society. Unfortunately, this translation is for the first edition of the book. Latest edition is available for free: http://prasolov.loegria.net/linalg.pdf (hint is you want to print it out, Amazon printing service is gre…

Oh so this is just a retire in peace .. I was affraid for a minute.

You thought he’d slipped into the null space, but instead he found his dominant eigenvector.

comments like these keep make me coming back to hn :) witty comments ftw !

I have a feeling that the intellect gap at a lot of universities isn't as profound as one would expect and that one of the reasons that the students of the best unis do so well is because their educators can actually explain the course material. You can do more when you've got to spend less cognitive energy on trying to piece together the hieroglyphic puzzle that lesser professors throw at you because they believe th…

i find that in general (not always) the smarter people are, the better they understand precisely what you don't know, and what you need to know to understand what they are trying to tell you it's a bit like the old "the more I know, the more I know I don't know" but with an addition of "the more I know exactly what I know, and exactly what I don't" and it's then applied via theory-of-mind, "the more I know precisely…

one related quote i really like is : "it takes a lot of knowledge to realize the extent of your own ignorance" :D
