Can someone help me understand the intuition behind 5:33? Why does the vector x move when the basevectors change but vector v is just lying there untouched? Shouldn't the vector v also move to a different position? Why is only the vector x repositioning? I don't understand the logic behind it

+iFoxx16 the intuition behind the x=A^-1*v transformation is quite simple. at first you're given the Ax=v transformation, that is the transformation A that takes the x vector and *transforms* it to the v vector, so going by pure math when you multiply the equation by A's inverse, you get the corresponding value of the x vector (which in the case of a real life problem you'd be looking for) and diagrammatically the inverse function of A takes the v vector and transforms it into the x vector. *So summarized A turns x into v so intuitively A inverse turns v into x* (Sorry for the long post hope it helped :))

+Abdul Adeshina Ahh, thanks bro. The video misguided me. I thought the video showed the base vectors changing in a linear transformation. But the intuition behind linear transformation is that you multiply it with a transformation matrice and your vector can change it's direction and length, it isn't the base vectors changing, I get it now.

These videos have the opposite effect on me than a regular lecture, they put me in a relaxed meditative state, concentrating on deep intuitions instead of a hectic state lost in calculations

I must tell you that I'm very impressed with your treatment of lin-alg in this series of videos. You've packed a solid chunk of a good LA course into a handful of 12-min videos, at a seemingly leisurely pace, with loads of intuition-provoking effects that help make the key concepts stick. It reinforces for me, the reason I subscribed to your channel. I'd also like to add - around the 1-minute mark in this chapter, where you're talking about the importance of matrices - a suggestion of another very strong reason: • the way they allow characterizing continuous, non-linear transformations as being locally approximated by linear ones. This really is something that makes them universally useful. It takes us into the concept of tangent spaces, and, ultimately, tensor calculus, which is the natural language of general relativity and other applications of curved manifolds, by relating nearby tangent spaces. Of course, this more full-blown explanation is well beyond the level of your series here, but I'm confident that you could drop the hints in a most understandable way about this, without going into unnecessary detail...Or maybe in a followup series that delves deeper.

I remember in college as a math major having the intuition squished out of me by the professors bent on formal rigor. I was never any good at abstract math after that. I am happy to see that intuition is making a comeback. I think that all breakthrough mathematics is a result of intuition. I really like what this guy is doing for the intuitives.

I feel you. Luckily, my calculus professor often provides geometric intuition for the lessons he teaches. That is what most professors miss in my opinion, they focus on us remembering the equations as opposed to having an intuitive understanding of what the equations mean, and their implications for other concepts in math. For example, I understood the concept of the derivative mostly through what it meant when applied in physics. This applied concept helped me understand the fundamental math behind it even more. Every class becomes a lot more beneficial when you focus less on remembering equations and focus more on solving problems.

I took linear algebra in college (it wasn’t even required for my engineering degree, I just wanted to learn more about it) and despite being taught how to CALCULATE all of these values, I had zero intuition for what they were. I didn’t even know that the kernel was the set of vectors that get mapped onto the zero vector by a transformation. They just told us HOW to calculate the kernel, not what it was. Same with the determinant. I finally realize why a matrix doesn’t have an inverse when the determinant is zero, because you lose information about where those original vectors were when you lose rank, because it becomes no longer possible or to reverse the transformation. I passed that class with an A and had no idea of any of this intuition, only how to get the answers I needed for the exams.

If we look at a matrix transformation that squishes 3D space into 2D space, we observe that a whole line (lines are 1 dimensional) of vectors gets 'squished' to the origin which in turn means that the nullity is 1. The rank of the transformation, we defined to be the number of dimensions in the output, which we know to be 2D. Now we see that rank(A)+nullity(A)=2+1=3 which should give us the dimension of our matrix A. Well, because we looked at a matrix that squishes 3D space this has to be true!

What you're teaching with these animations could never be accomplished on some lecture slides. Thank you!

I love this channel! I can't even describe how enlightened I feel now. I've been totally lost in math classes during my master's and PhD. Now I feel I can actually understand the concepts I've been trying to use all those years.

It's unbelievable how these animations make it so intuitive and easy to understand while dry text from a book has the opposite effect.

I find my self thanking you every few videos.. You help enlighten us with the very missing concepts that no lecturer of ours (university), as it seems, dares to delve in to while constantly and rapidly firing at us computational babble! I was laughing out of hopeless frustration during the lecture today (I would cry if else) and your unique time invested videos really contribute in restoring emotional balance in upset students like myself..

It's amazing how many properties of rank, nullity, and column space instantly began popping into my head watching this. In my abstract linear algebra class we were so focused on pumping out proofs about n-dimensional vector spaces that I never really got these. It makes sense that nullity and rank add up the way they do

Thank you very much for this series! I was able to solve questions of linear algebra before but never really understood the meaning behind it. You're a gift to education!

Holy sh*t! I'm finally understanding it! I have been trying to self-study linear algebra for about 3 days now, and nothing was really making sense intuitively, till I watched these videos. Thank you so much!

Take notes professors, this is how teaching is done.

You’re a hero! Very intuitive when viewed geometrically. And the visuals accompanying the explanations are top-notch. Thank you, and well done!

It's really incredible ... during my studies of linear algebra in Computer Science degree - almost 20 years ago - no one explained in this way and everything was very abstract and to be memorized without understanding what it was !! Compliments, I'll follow also your Calculus set for Analysis

I've finally understood it.

For some reason, I was so excited for this video to come out. This was the highlight of my day. I live a sad life :(

me too, I get even more hyped now that they are published every week rather than everyday

These videos are pretty cool, they get to touch the core of mathematics and life. I don't think one such video being the highlight of your day necessarily means you live a sad life.

The only thing sad about your life is that you think that's a bad thing

Aeroscience but dont lie, seeing in your subrcriptions a video of this channel really hypes you up

Unlike other videos who just explain how everything is as it is, you really dive deep into why it is right. You are the reason why I finally understand all of these concepts, by just watching the video once.

I really appreciate and love how he emphasizes more on INTUITION part than COMPUTATION...!!! Thanks!!

I am reborn after watching this playlist.

Waiting for the next one with bated breath!

Wow what a brilliant way to explain the inverse and identity matrix! This world needs more teachers like him.

This series makes math seem beautiful and exciting and I am here for it

I know that you have a lot of videos planned after the conclusion of this invaluable series, and I'm indescribably excited for whatever it is that you decide to cover - but I personally feel wrapped up in, even lost in the world of Cantor; I feel as if I'm skirting the edges of a real intuition for the realm, and something tells me that a video or even series of videos by you on the world of infinite ordinals, inaccessible cardinals and other awe-inspiring entities that inhabit the endless would help me scale the wall. In any case, thank you immensely for all your effort and your tremendous efficacy. You've helped myself and surely many others break through more completely into the wider world of mathematics. Time to start counting down the days until the next one!

you re a god man. this series is so great.

I got a solid A in my Linear Algebra course, but I have taken away more intuition about the subject in these videos than I did in that course. It isn't a slight at my old instructor either, you are legitimately an amazing instructor. Thank you so much for giving us these gifts.

Best tutorials ever. Most practically explained linear algebra videos . Can't find such material anywhere.

first of all, i really apreciate this videos, are extremly helpfull and im gonna recomend it to my math teacher to share it with the people, but i have to ask for references about how to solve this things, unfortunately (for me at least) we cant use any type of electronic equipement for the math exams, no calculators, no pc...

"this isn't meant to teach you anything" proceeds to explain everything i didn't understand

This is such a beautiful course. Very nice visual representation. Thank you!

I'm really glad that you've been posting such a great course about liner algebra. Thank you!

this is oddly relaxing. like i could see my mom enjoying this

I would nail my linear algebra exam if I could find this series earlier

thank you soo much for this wonderful playlist!!!

Compared to ALL the other math teachers and professors I have had over the years, you NAILED it.

Holly shit, after 2 years in math engineering you blew my mind at 2:47, now it all makes sense!

@Pedro Takahashi Gunderson apparently something that doesn't help you learn linear algebra in any reasonable time scale.

My professor started the lecture by showing this video.

Excellent explanation - makes doing the computations (for class) a whole lot more enjoyable too.

This channel is absolutely mindblowing. Thank you so much!!! Please make more of these!
