Curses! I thought this was finally the answer to the dissonance I feel dealing with vector spaces coming from data analysis. [Yes, despite the row/column operational equivalence, the baseline pedagogy is *slightly* confusing] Not that anyone really wants that mess of crazy to make more sense,...and I have to reformulate that more cohesively before I even try. But for that brief moment, I thought the nonsense in my head actually had a cause! Eh...maybe someday you all can bask in the bedlam that is abstract analaytics.

Ephesians 6:10-18 says, Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; and your feet shod with the preparation of the gospel of peace; above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God: praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints. The bible is no old book. You have to really let Christ open your eyes; to see the world in shambles. Many people say it's a religion to lock up people in chains, and say it's a rule book.. why? Because people hate hearing the truth, it hurts their flesh, it's hurts their pride, it's exposes on what things have they done..people love this world so much, s*x, money, power, women, supercars.. things of this world. Still trying to find something that can fill that emptiness in your heart. You can't find that in this world.. only in Christ, the bible is no chains, it's a chainbreaker. Breaking your sins into pieces... Repent now, and turn back to the true Lord only.. God bless. 😢😢😢

The way you explain everything is so easy to understand. You start off assuming I don't know anything, and slowly build up to more complex topics, all within the timespan of 10 minutes. It's so easy and approachable, even for someone (like me) who hasn't even learned the basis that this is build on. Your teaching style is really great. Keep up the good work

[@mobyj4794]

If there's anyone like me with virtually zero prior knowledge in linear algebra and feeling like an idiot not understanding what this series (particularly the later videos) is about and why many others are praising Grant, I suggest you pick up an elementary linear algebra book to understand the fundamental concepts before continuing on. This lecture series focuses on the intuitive side of linear algebra, but I personally found it hard to gain intuition when I didn't know what LA tries to solve in the first place. After you've gone through the more formal basics, things will start to click. About two months ago, I watched the entire series of lectures understanding only abut 30% of it, now I'm back and this series is supplementing my knowledge very nicely. I hope this helps anyone that feels the same way I once did.

Could you possibly make a course on the essence of probability, chance and statistics as well? Thanks so much for your work! Love your style and videos!

[@b1gb017]

Love that idea

[@sabrinapereira7673]

This is amazing. I feel like I've learned more with your 9 min video than my full 4 years of algebra in school. Thank you!

[@Inspirtedmusic]

I can already tell that this video series is going to be phenomenal. Well done, ill see you on the next one!

That was a good explanation! I undestood better than what was in KZbin in my mother tongue. Thank you! Keep going with this good work!

[@whitelotus187]

you are the best teacher on youtube.

[@nunyabusiness3786]

You can no longer bamboozle me with your science for I have gained knowledge

[@JesbaamSanchez]

Im taking Linear Algebra rn and I got to say Im learning wayyy better with your than what my professor can teach during class (emphasis on teach... He goes according to a book he doesnt even teach the class the book does)

[@sudhirh1573]

thank you so much, can't appreciate enough to help make people understand in a simple & yet effective way.

[@monome3038]

Can't be thankful enough for the amont of effort and research done to explain so simply and illustrate so well all the steps! This video took you some time to make. Thank you so much!

[@twinbladevolt8679]

I love this channel. I feel like such an idiot all the time in math class because I don't understand it and the teacher says I should know this thing or whatever, but then I try to catch up and this breaks it down in such a way I can visualize EXACLTY what's happening and then put that on paper into the proper equations.

[@thomasshaw6169]

This has to be my favorite math channel.

[@chuksjr.1440]

It definitely is!

[@TobySimone]

I think this is my first video of yours I've watched and I can already tell I'm going to love your channel. I'm somehow excited to learn linear algebra now, something I could have never imagined saying!

[@japonjapon6242]

hello 😂

[@mavick.]

yeaah! I think the same!

[@cchuang0730]

I realy appreciate your video. Although I've got my engineering PHD degree for years, your videos inspire me very much. I got chances to review what I've learned from a strait-forward visualiation way. I also introduce your video to my son, who's a high-school student, to help him got the algebra ideas rapidly. Thanks!

[@andrexeme_swag]

Blimey, the way you explain is simply masterful! I've watched plenty of your videos and still can't help but think to myself how terrific your videos are.

[@lamalamalex]

That awkward moment when you’re the physics student, mathematics student, AND the CS student 😅 and you had to deal with all three perspectives.

I majored in math in college. I relied on my math degree for other careers, flying and law, in varying capacities. I'm now considering a new career in teaching. I can say that you are the best math teacher I have ever encountered. So, fwiw, I really appreciate your refresher courses (to me) as I consider changing careers one more time.

[@steven21736]

What sort of law did you practice?

[@KRYoung_dev]

Thank you so much. I got into a sort of ML bootcamp, where I suddenly find that ML is just math with a fancy coat of paint on top. Well, I majored in art and psychology, got a D in calculus 14 years ago, and never even took linear algebra. So my anemic math skills are hampering me in an extremely fast-paced program where it's like they are speaking a different language every time somebody busts out the Greek letters. Looking up these essential mathematical concepts mostly just brings up *how* to solve test problems and complete homework, whereas for ML you need to understand *why* these methods work. Thanks to your videos, I can get up to speed in minutes instead of months. I'm really, really grateful!

[@scnt]

Please never stop making videos, you are my math guru 😃!! And I absolutely 💯% love the way you teach each and everything with a broader perspective, I mean just amazing!!!

[@kietpham4635]

When I was in school struggling to make sense of this and I couldn't, my questions annoyed my classmates. "WHY CAN'T YOU JUST FOLLOW THE FORMULAS? " I wish I found this at that time

This man should be given a nobel prize for such terrific teaching. Thank you so much for producing high quality content for free!

Only nine minutes but with big efforts (scientific material, auditing the material, script and graphics motion) with production management and then FREE for people. Thank you very much for teaching us.

Sir, you are a vector. Thanks for providing us magnitude and direction to do math easily. ❣️❣️❣️❣️❣️

[@thegil-martingetaway8804]

Geography major at Edinburgh here. Feel like the only one coming from this background, but i'm trying to break into the world of remote sensing and geomatic engineering! Been slowly working on my thesis which requires principal component analysis, so wanted to come here and understand how the hell 'dimensionality reduction' and 'principal eigenvectors' apply to socio-demographic data. This is without a doubt the best series on the internet for this topic, and has brought me more clarity than any professional in the entire school of GeoSciences. Thank you Grant.

[@Dannnniel]

Hi im a first year maths student and have just started the linear algebra module, this alone has helped me so much already to understand actually what the last 3 weeks were about, I can see the rest of this series is going to be so helpful thank you! :D

[@odthegreatest]

I wish KZbin existed when I was in university. Such a lucky and unlucky generation right now. Like the Schrodinger's approach. Until you talk with them they are sharp and dumb at the same time. Yeah vectorsss

This isn't uni level right?

Gen zer here who really appreciates your perspective on us. The schrodingers approach is pretty accurate id say, even though I see a lot more negative/struggle overall.

I’m here to join the thousands of people here commenting this is a fantastic series to intuitively understand how linear algebra works, if I found any fun in trying to make sense of my Linear Algebra university course it’s only thanks to you 3b1b :) I hope I can teach my sister, now in uni too, what I understood, but I’m definitely directing her here
