I am certainly glad to see a professor who teaches from his brain, not reading from power point slides. This is refreshing.
lol I'm about to say that
It most certainly is! It's so captivating as well.
Wow, the first 2 minutes of this lecture explain the topics better than 1.5 hours listening to my current teachers.
True)
I so agree, wow
you weren't paying attention in the class, let's be real
@@HK-sw3vi No my teacher just has a VERY heavy accent and he wasn't on rate my professor so I went in blind.
In which college u r ??
All math and engineering majors should be required to learn Linear Algebra from Dr. Strang. His lectures are beautiful, crystal clear, and emphasize the big ideas of the subject, and how they connect to one another.
Arlo
I wouldn’t say crystal clear in my opinion.
@@lucasm4299 compared to my professor, clearer than crystal XD ... My professor shouldnt be allowed teach
@@mikem9270 I agree. My professor couldn't explain what Dependent and Independent vectors are properly and every student in the class lost their shit.
Man... Wish my linear Algebra classes were as half as good as this one...
This is simply beautiful.
same bro
It's a treat to the brain. He is explaining like a person does not know anything about the topic but still can go through the lecture. Hats off to the professor here.
GILBERT STRANG, YOU ARE A GIFT FROM THE HEAVENS!!!!!!!!!!!!!!!!!! I HAD NOT UNDERSTOOD ANY LINEAR ALGEBRA WITH MY LECTURER AND YOU ARE NOW SAVING MY LIFE!!! YOU ARE B E A U T I F U L , thanks for changing my life 😩😩😩😩
This dude wrote the text book im referring for linear algebra! His lectures are as amazing as his book!
mustard seed
Yup and most importantly it talks abt. the APPLICATIONS which is more important.
mustard seed
But sadly I have the book in PDF format..
Can you email me the pdf or direct me to it
What is the name of his book please!
I WANT HIS BOOK! Expensive though, you can't get it free, right?
1,0,0 is a better A3... then.. that loser, that 6,3,5.
LOL he's halarious.
1,0,0 What the heck!
*than*
He’s an American professor :)
First video in the series Dr. Strang did not start with "Okay!". I love the work he has done and his effort to provide quality teaching to the world! Thank you!
A beautiful lecture! For the first time I understand basic terminology of Linear Algebra! Phew! There's a special place in heaven for you. There's a reason why MIT is MIT
I am glad people like me who did not get into MIT can take MIT courses. All the videos I saw from MIT are very clear, easy to follow, and well-structured! amazing
This lecture series shows vast improvement over previous eras; its total lack of fluff, jokes, anecdotes, it's just non-stop content in a nice little 13 minute package. I'm reviewing in the background, it's a great refresher even if oriented towards new students.
It is amazing how Professor Gilbert Strang manages to explain such an abstract mathematical topic with so much detail, yet making it easy to understand. He has all the qualities of a good teacher.
You are amazing sir... Education is all about transferring your intuition to others... You always great in that.
Thank the lord for this man. My teacher can't teach in a way that makes sense for his students, but Dr. Strang made it all make sense.
First 2 minutes of the video are more than sufficient to kick off any vector space problem you'll ever face in exams. Thanks for preserving quality education, I am really fed up with brainless professors these days trying to print formulas in brain. Thanks MIT and IIT for preserving quality education
Oh god, I paid $6000 for a Maths course in uni and barely understand teacher talking about, and it turns out free RUclips video helped me understand every single concept. Imao
professor like Dr strang produces brilliant student , and the student are the reputation of the university . 20 lecture of my professor= 13 min lecture of Dr strang .
You are a life saver, huge respect for the way you teach. Finally I understood all of the concepts after struggling for about one year. Hatsoff. Thankyou so much Sir
He called one of the vectors a loser. Thumbs up for this video. Also, Strang is great because he keeps simple. KISS is too long and he knew this. It's KS, and the K is only there for clarity.
Thanks to Dr Strang, I can now visualize what does all concepts represent. The things are very clear right now.
9:55 dimension = # of basis vectors for the subspace
Am reviewing LA and have not done it in over 20 years. This first lecture of Dr.S, as many have commented, is very clear and simple. Thank you Dr. S DVD:)
The best professor I've ever seen. There is the MIT!
My deepest respect to Professor Strang. Respect to his perennial enthusiasm, and all those years he had devoted to his field.
Every time I watch Strang's videos everything makes so much sense and I wonder why I hate Linear Algebra so much.
such an awesome guy! That's how math should be taught! You can never get bored while hearing Dr Strang's lectures..
Prof Strang, you are now deeply thanked by a man living far far away from the USA. God bless you, God bless MIT, and God bless America!
Now the idea is crystal clear in my mind. It has taken more than 5 years for me to get this and it happened in just 13 minutes. Thank you. Thank you.
Been wracking my brain for two days..listened to one line of his explanation and I got all the clarity in the world.
This is best explaination i have listen for basis, dimension and subspace. It explains everything with connecting one idea to another.
Bmte 141?
Lemma if f: A -. B is an affine map then the map L,: A-a -. B-f(a) defined by
4(x) = f(x+a) -f(a)
is a linear map. The map f is obtained from Lo by the previous construction.
god i love this guy. hes so chill bro.
Explained everything perfectly. Damn
Basis is a bunch of vectors and dimension is how many vectors.
In a single sentence, he sums up what wasn't made clear in so many other lessons and videos and lectures.
5 sections of gibberish laid out in 13 totally crystal clear minuets. good lord this is magic
You're the best, professor. I am studying from the 18.06 in spring 2010 and you explain everything very clear. Thank you!
One like is certainly not enough for your enthusiasm and dedication Prof. Strang.
Professor Strang is a genius math teacher!! This is how math should be taught.
I came from the lecs of linear algebra of 2005 , and i see how him grew up, omg, he is the best!!! i wish i has professors like him.
God what a godsend .. been trying to get these simple concepts for so long and finally one video did it!
I read the book, then I come to Strang's lectures and I am always all like "oh wtf, yeah it makes sense now"
WOW, he really made it more easier for me to understand and his really good! I like how he explain the concepts and meaning of those terms first before teaching about it.
What a pleasure it would've been to study mathematics under Dr. Strang, and physics under Dr. Feynman. Two luminaries who cut through the jargon and teach.
explained very well. wish he is my professor! thank you!
He is your professor. Aren't you studying from him? If yes, then he is :)
i finally understood after just 13 minutes of his lecture compared to the 1.5 hours rewatching my uni's lectures and trying to figure out what a basis is. Thankyouthankyouthankyouthankyou
Thank you so much . Have been trying to understand this concept but haven't found a right source which emphasizes on the practicality of the content rather than a textbook definition until this elegant lecture.
These topics are important in linear algebra. DR. Strang explains these topics very well in the video.
this is the best lecture so far
Hi, I would like to thank this gentleman for the idea of the dimension presented. It will help me better understand the definitions of Linear Algebra books.
you are a legend, this is so much more clear than any other explanations ive seen
Subspace: không gian con
Basis: cơ sở của vectơ
Column: cột
Dimension: số chiều
Amazingly explained, I've been trying to figure out this stuff for so long and you explained it beautifully
So good to hear and learn from u sir,
Clear my fundamental about dimensions and basis very well. Yup better than hours of class 🤟🏻
Thank you sir, you really helped me. This video is soo understandable. You explain everything soo well. This is full of information and short at the same time
“That loser 6, 3, 5” 😂 Strang is an exceptionally gifted lecturer And an absolute straight-faced blast. LOL
This was so simply explained that I'm in tears. THANK YOUUUU!!! ♥♥♥
you deserve the whole respect Prof I would like to thank you so much .
This guy CAN TEACH!
Excellent explanation with full understanding......and i think i can now clear this topic with a little bit of example solvings....never found such a good explaning teacher than sir. Dr. Strang
Make some more videos like this because there is no good education in my institution
We thank you for sharing such informative video with us
Wow!I have never seen such like lecturer....amazing, brilliant for sure!!
Thank you professor.. Now i have finally understood something that has been puzzling me for a week..
This video provided me with a very Strang introduction to the concepts. Thank you.
beautiful explaination bringing key concepts together, adding visuals and bringing them to life! This is one of the greatest explanations I have heard in my education thus far.
You're an angel sent from heaven! Thank you so much for these wonderful videos!!!
thank you! Dr. Strang. You invoke my interest in math as a math student!
you're the man Gilbert Strang.
Bruh what a G. He made it super easy. Thanks, profe
May Allah guide you to the light of ISLAM
Thank you MIT OCW and Dr. Strang!
Good video, thank you. I find this stuff really confusing and this really cleared things up
This video cleared all the ambiguities of mine related to these terms a big thanks to Sir....
Best teacher i've come across thankyou so much for saving us 😭
he explained 15 classes of university's schedule in 15 minutes!!
His voice makes learning Linear Algebra fun
Only depressing thing is that Prof.Strang is getting old ,wished he were half of his present age ,more gems from math we can get.
omfg i love this guy and his explanations actually make sense!
Thank you so much Professor, now my confusion on this point is "crystal clear " This was a marvelous & interesting lecture.
Thnx once again...
This guy is the real MVP
god bless you sir, i havent understood this this shit for 3 months till i found this video!
I wanna hug this man
God bless this guy
This guy is great
not like that 6 3 5 that guy is a loser
10:10 explained Dimensions for me so much better than the textbook.
Thank you so much for sharing these lectures-- You've helped me so much!! Pure love!!
😔 ....... Please upload full video cource in RUclips or any site for those student who not get chance in MiT but want good concept with Clearity...
This man is such a treasure! Great lecture
Subspace explained beautifully at @8:00
Thanks for explaining this. I get the idea in first 2 minnutes.
It's really a service to humanity.
I love you sir!!! you are a healer!
ive never had it explained so well like this, thanks
You're a Legend Madala
Thank you so much
super cool. such a life saver for my exam!
Finally got the idea of basis right. Thanks, Prof Strang!
Wow! What a brilliant explanation. Living legend❤
thank you very much for all your teachings!!! much love from Brazil!
Please just confirm if these dimensions, of the terms in the field equation, found on the internet, are correct or wrong.
[G(miu,niu)]=M.L^-1.T^-2; [R]=[Lamda]=L^-2; [g(miu,niu)]=M.L.T^-2; [T(miu,niu)]=M^2.T^-4. And if the dimensional homogeneity of the relativistic gravity equation is checked with these dimensions of the tensors and curves in the field equation?
Many many thanks for your good explanation!!
Thank you so much Prof
the moment he explained nullspace, i finally got it
This video made me realize how long it’s been since I heard chalk
