Gil Strang's Final 18.06 Linear Algebra Lecture

[@johnstrang9300]

Posted on behalf of Gil Strang: This is my chance to thank everyone for such generous messages about my last lecture at MIT. I am almost tempted to have second thoughts about retirement ....... but it is the right time. Teaching has been a wonderful life. And I am so grateful to everyone who likes linear algebra and sees its importance. So many universities ( and even high schools ) now appreciate how beautiful it is and how valuable it is. That movement will continue because it is right. I thank you for your good thoughts. I appreciate them more than I can say. Very best wishes in all your work Gil

His lectures emphasised the different ways to think about linear algebra instead of just dry formulas. To this day, I still remember and use his column picture and row picture of matrix multiplication (each column of AB is a linear combination of columns of A) - this is seldom taught elsewhere but it really helped made a lot of reasoning with matrices and linear algebra a lot more intuitive. Used these pictures many times even when learning more advance math and my classmates seldom know about it.

I self-studied linear algebra during the summer of 2002 with his textbook and lectures (via Real Player, if I'm not mistaken), then breezed through the course at my university that fall. Those videos are the main reason why I share my own (microeconomics) lectures & videos on KZbin.

Thank you. Seeing prof. Strang videos all I feel is gratitude. Around 2007, as a PhD student, I watched his youtube videos on Linear Algebra and they rescued me. They probably had more impact in shaping my career than anything else that happened then. I even wanted to add these lectures as a reference to my NeuroIPS paper.

I decided to self study mathematics from scratch. I learned linear algebra via Strang on youtube...and never took a formal class in linear algebra. I am now starting a math PhD. Thank you for your beautifully written introduction to linear algebra and for the amazing lectures, Professor Strang. I hope to be as great a teacher and academic as you!

[@alfredomulleretxeberria4239]

How'd you get into a math PhD program without having a bachelor's degree in Math?

[@dark_art1]

A professor that will live forever, not only for his unique way of effectively teaching math, but also for his extraordinary ability to make students feel seen, heard and special. Thank you so much professor Strang!

[@JackLangerman]

living legend -- changed my life and helped set me on the path I am on today. Thank you Professor Strang. ♥

[@Jvo_Rien]

My kid learned linear algebra from your videos when he was 6 while he was rejected in France. I really thank you for making Dr Strang's teaching freely available.

[@shocktocker8282]

AMAZING career, Professor. USA has been blessed to have you teach our children (AND our kid's kid's!). NOW is the time. Look at great athletes who come back after retirement....

[@RASULSHABAN]

Thanks MIT opencourseware and Prof Strang for the Maths online lectures. I learnt and applied alot of algebra/matrix applications in my finance lectures. It is a pleasure to share your works for maths understanding. Rasul Shaban-Uganda

Professor Gilbert Strang’s lectures truly made me more interested beyond what I was learning in the classroom. The way he conveyed, the way he encouraged, the way he showed and told a story with math or showing how to tell a “a story” with math, all of it and more kept me engaged or explore even if just a little beyond discussions in class. These VODs re-flourished my appreciation and excitement for math after having it snuffed off by many monotonous professors or instructors who’ve made me eventually take on “just taking this for the credit requirements but idk why else” mindset before I realized it-and this is me coming from the MIT of the South, tongue-in-cheek. Thank you tremendously MIT OCW and Gil Strang for all you do and inspire to do for the betterment of the world, generating, disseminating, and preserving knowledge. I am joyed that Professor Gil has seen the generous messages and testimonies of his impact and legacy. I wish a blessed well-off retirement to you sir Strang!

[@ReveredDead]

61 freaking years?! Holy crap....he's been teaching longer than my own dad has been alive.

[@marklamias7763]

Congratulation on your retirement Professor Strang! We are forever indebted to you for your carefully crafted lectures and education you have brought to so many. I must tell you that I took my first two linear algebra courses from Richard Canary at the University of Michigan and several years after graduating, I needed to refresh myself on some concepts from the courses I took. Your material was the only really accessible material I could find and was perfect in every way. Succinct, yet sufficiently detailed for a post-graduate student needing to refresh his linear algebra skills prior to running some advanced simulation models with heavy use of matrices. Thanks again for all you've done. I hope you enjoy your retire and know the impact you've had on countless people and the applications, inventions they've subseqently brought forward that youv'e had a hand in, in some sense!

Thank you Prof. Gil Strang, I love your lectures, kindness and humour. Thank you for the 61 years of teaching the world.

The standing ovations we all want to see ! This is absolutely fantastic age is surely limitless ❤ kudos to his patience his knowledge

[@birgula.t.2965]

Thank you so much Prof. Strang. We will keep listening and suggesting your lectures.

[@ashirwadgarg174]

I can't believe this is his last lecture. 🥲Sir you are G.O.A.T of linear algebra. Thank you sir. Love from India. ❤

[@xiongcezhao3119]

How lucky for those who can attend this lecture in person! A legendary scholar and great teacher, salute.

[@shocktocker8282]

Fesser- congrats on teaching a complex subject at such a high level over so many years. Thx to MIT for allowing this open course to be broadcast to the public. NOW that I'm retired I enjoy learning from videos like this. Would be GREAT if you could do KZbin videos for public consumption, it would be a contribution to humanity! Good luck & continued success!

[@borjagarciahaendler6938]

Big applause to Gil ! I learnt online Linear Algebra thanks to him!!!! I cannot express my gratitude enough!

[@justalpha3429]

Total respect. Thank you Proff.Gil Strang🙏

The best channel on KZbin A platform for spreading science, culture and knowledge With the aim of developing societies and enhancing the capabilities of university students around the world ❤

I watched his lectures as a computer science student in Serbia, through MIT's open courseware platform. They were incredible and changed my perspective on many things, including whether to continue in academia or go to industry. It helped me decide to pursue a masters program at ETH Zürich, where I graduated with honors and then went on to Google where I still work as a machine learning team lead in search quality. Thank you professor Strang! You really had a profound impact on the course of my life.

Thank you Prof. Gil Strang, I love your lectures, kindness and humour. Thank you for teaching the world. From Pakistan

[@likeapple1929]

Sending love from a Chinese student! When I was a freshman in Australia, my English skills weren't great, and I had trouble understanding some of the content in my linear algebra course. Gil's book was the first book I read in English, and it made a huge difference. His course and book were super helpful, and I ended up acing linear algebra with a H1 (like an A+ in the US). And it's not just about the grade-I genuinely gained a deeper understanding of linear algebra thanks to his book.

[@yang7436]

Beautiful story🎆

[@mkryszak]

Bro how did you manage to study in Australia? It's freakin' expensive there 😅

Professor Strang and the MIT Open Course Ware single handlely gave me the extra content I needed to gain the confidence going into most of my engineering finals. I really appreciate everything Professor Strang and MIT has done for me. Thank you.

[@Pastor_virtual_Robson]

uma despedida muito comovente. felicidades ao professor Gil Strang . Abraços daqui Brasil.

[@alienxna6511]

A true privilege to have watched this and what an amazing and humble man. If I had had a few teachers/lecturers of Gil's quality, maths would have been so much more relatable and enjoyable. Trust Gil is enjoying his retirement and am sure his legacy lives on.
