How do you spell linyeraly (me trying to spell it) you said the word in the qualitative section at the start but I couldn't really read the writing (I'm writing this down in my book)
I'm taking electrodynamics this semester at UT Austin, and we are using Griffiths 4th edition. I am so impressed and grateful that you have made the painstaking effort to produce 201 videos on this textbook alone. Thank you.
I was never good at math. In fact, I never passed grade eight mathematics but when I listen to you and watch you draw an explain what I'm looking at, I get it. I completely understand the concept, even though I don't get much of the math. Thanks for making me a little smarter!
Wulfle i only failed in maths in grade 5 (last year) because my teacher (Mr k) exspected everyone to know everything in math. infact i sucked at it but now this year and the end of last year im starting to get B+ instead of C now im aiming for A+ but the bad thing is the job i want i have to be good at physics and math and all that stuff (i want to be a vet just incase you were wondering)
That physicist who deduced the magnitude of atomic bomb by the tiny piece of paper was Enrico Fermi He was famous for his superquicj approximated calculations
Michael Bruce Allen Books can certainly cover course material to the extent that they can be a "course", i.e. 'A Course in Plato'. But it is not a course in the sense of going to class and getting work done. That, and the fact that books tend to be much more affordable!! But on the whole, I think that books are more memorable (depending on the book) than courses per se.
jamesdragonforce It's too bad our generation still equates class time with education. Education is what you do to yourself. Class time can only help inspire you to action. You're absolutely right that books are better than classes. I'm hoping my videos can be a drop in the bucket that will change our world's attitude on education.
+jamesdragonforce And the internet is much better than books. Like for example, I am learning programming in Python and I would have never been able to learn from reading books as I am more a visual learner who can learn better from videos on certain subjects!
+Freak80MC I'm finding there is a large population of people who simply need to see and hear to learn, and now that it's almost trivial to produce videos and lectures, they are finally plugged into learning in a way that only the readers and thinkers were able in the past. This is opening up a number of subjects to a wider audience for the first time, and it's exciting to see it all unfold. (On the other hand, I learn by reading and I can't sit still during a video!)
1:10 wow, that is currently the state i relate, i learnt a lot of math back in the months, but i still dont consider me a mathematician, just a person trying to gather his tools to do some kind of job :)
I. 38 years old I was shit at math in hight school I loved maths and science, I don’t have the money to go to uni, now I’m self teaching mysellf, iv been better at the maths more than ever, I understand what calculus is like the meaning of it, I’m useing Khan Academy, cosmolearn, UA-cam, and now if I can pull it of I hope to get a diploma from the Edx hopefully by Christmas or next year site or the certificate. I have done a lot of derivative and I love useing the pdf but. Input I haven’t done the rest of the sum on calculus on khan academy, I used to love math and science but just by tinkering with it and practicing more than playing with it with computing and technology it became with my strongest point,I want to follow on from where Stephen hawkings left of he inspired me, I’m not trying to be like anyone I did whant to do it after school but I had othere things planed, but now I hope I can do it before I die whenever that may be, I want to look back and know i a mend my failures in life and I accomplished more than I used to I know I can do it, ever since I have left hight school iv noticed I can do more than I throught I could. What confuses me is look throught chi’s site called freebookcentre.com, on the basic sections, I am on diffraction section the now, but I don’t know whether to go throught the geometry type books like diffrential geometry, algabraic geometry and the basic book section first, there a tones of pdfs like one on highter algebra with 15558 say pages, or should I just continue on my calculus journey then do the what I said above, I have allways love reading, solving things, and story of my live iv allways been analysising things I mean everything apart from myself ever the Rudy bible, I mean it’s rediculouse it’s like iv allways had an addiction to anaylising thing, maybe now I have a hobby I should have continued after hight school insteD I f making mistakes in life, but on my math era physics journey I need to find out wich way to go up level by level or mixed.
My recommendation: Go through Basic Mathematics. Once you've got all that material, then you need to learn just the basics of calculus. That would be derivatives, integrals, and just a little bit of differential equations. At that point, you can pick up multivariable calculus and that's enough to do most of undergrad physics.
No Ph.D. I went into software because that is my love in life. I went into web development because that was what was needed and there are interesting problems there. Now I'm in machine learning.
I don't know, but what I know is there are constant values or variables for every symbols. That is if you're trying find another value. Then you'll apply mathematics in it, Haha! For example if you're trying to find let's say how long the Sunlight reach Earth. You'll divide the known distance from Sun to Earth then divide the factor against the speed of light then again in minutes. It's quite obvious speed of light can't amount to hours to reach Earth. If I have only known that I'll be interested in Astronomy later in my life, I should've taken my Physics seriously during my college days.
I think you're on the right track. There is a sort of map you learn with physics. If you know X, then Y and Z are around the corner, but you need to know A and B to get there.
That was a really good, simple, and effective explanation. I passed Calculus I and did Math for the Real World. I passed both of them with a B+. So, I stuck to the courses I was getting As in, which is Information Technology. I do love the idea of learning how things are related to each other mathematically.
Yep. As you learn more and more physics, you start to see a pattern in the types of things you learn. I find that TV pop physics does a good job of explaining things, but never ever ties it to math, so there is a huge gap there. Most of the beauty of physics lies not in the cool special effects on TV, but in the math behind it all, which is so incredibly elegant.
I'm not free, unfortunately. Recently, the company I work for has been acquired, which is a good thing, but we are actually doing fun work for them now and so I spend my working hours thinking about that rather than physics. At the time, I had a thought of going back to Physics or maybe just getting a PhD in ME or something, but now that is a distant dream.
And now I have some time. I am probably going to do introductory physics (freshman course) + calculus + EM before I get to classical mechanics. I definitely want to do classical mechanics before QM, though. Eventually, I want to get into Jackons and QFT.
Just be sure to give your brain plenty of time to process the ideas. You can't rush physics understanding. I remember staring at formulas for hours trying to get a feel for how the quantities interacted together. It was not time wasted.
Hey guys, I'm rebooting my channel! Subscribe and watch my new series on Basic Mathematics by Serge Lang. Thanks!
Real Physics plz discuss all the vector quantities and their formulas , this is really a big hurdle-- thank you

Nice video = ) Really helpful
Thanks!

I'm taking electrodynamics this semester at UT Austin, and we are using Griffiths 4th edition. I am so impressed and grateful that you have made the painstaking effort to produce 201 videos on this textbook alone. Thank you.
I'll be taking it this semester (Fall 2020). Would you recommend this as a good guide for the class?
Guillermo Highly recommend this text for that course, even if supplementary.
I'm currently enrolled for electrodynamics at UT Austin! So awesome that I saw this what a small world! Anyway, how helpful were these videos?
@@theaveragemegaguy It is a small world! I recall using these videos a lot. They certainly felt helpful at the time. Good luck this semester!

strawberryblast2004 AJ Well helping animals is one of the most honorable carriers someone could have.
:) SO RIGHT but i don't know how to do physics i want to know now so i wont struggle :I
................ ok lol you know i didn't even watch this whole entire video only a tiny bit like 5 seconds of the start lol
Wulfle I love math!
This is really, really important. I wish I could have seen this last semester when I started Physics I, but better late than never!
Great little video that gave me a lot of perspective about my future education.
Thanks brother

Books are much better than classes.
jamesdragonforce Is it not possible for a book to be a math course?
Michael Bruce Allen Books can certainly cover course material to the extent that they can be a "course", i.e. 'A Course in Plato'. But it is not a course in the sense of going to class and getting work done.
That, and the fact that books tend to be much more affordable!!

3:21 Does that say the integral df/dx? I can see that the derivative is equal to the function stands for dx=f.
Thank you for your time man you are Just great.
1:10 wow, that is currently the state i relate, i learnt a lot of math back in the months, but i still dont consider me a mathematician, just a person trying to gather his tools to do some kind of job :)
As I get older, I realize more and more I am more of a hands-on person than a theorist. Math is nice, but unless it is practical, I find it tedious.
The guy who dropped the bits of paper was Fermi :)
read that story in Programming Pearls. it was given as an example of back of the envelope calculations.

how much algebra do you need to learn
These are great videos! Just curious...how did you go from physics/engineering to web design? Do you have a Ph.D? Not that it matters!

+jg394 Learning Physics now for me won't matter anymore. Well, maybe if my grandchildren will be interested in numbers. Thanks for the attention :)

I know this one.. after 2 semesters of neglecting the qualitative aspect, I had to start from zero all over again xD
You saved my life for 2nd year E&M. I'm basically forever in your debt
Thanks. I'm going to start making videos again so your comments and advice are welcome.
Hey man 👋 , love from INDIA 🇮🇳 ♥
if you are free why don't you make videos on classical mechanics covering goldstein for example . I really enjoyed your video.
I'm not free, unfortunately. Recently, the company I work for has been acquired, which is a good thing, but we are actually doing fun work for them now and so I spend my working hours thinking about that rather than physics.

Thanks for replying. Best of luck for your future.

I am getting irritation with that pen sound but best video
Little problem for me English language... 70 percent lecture understand
can u plz tell me how to learn physics derivations easily ??
calculus might help.
I feel bad about not understanding what he is saying even though I'm in grade Seven.
+Villager263 Don't feel bad. There is a lot of bad physics education out there.
I'm in seventh grade too
Helpful video!
Thanks!
Yay
I couldn't understand any thing bro
Sorry. I have since bought a new microphone, and I'm trying my hand at actually editing my videos.
Physics is so fine chem is so boring bio the best
Physics the best, chemistry is fine, bio is so boring.
All three are awesome! Also geography.
Geology isn't a science (sarcasm)
I am in sixth and my worst subject is physics...shoot
Izma Qamar
It's a hard subject. You'll get it eventually, we all do (:

its bro difficult to get ur english
It's so difficult to get your English
Sorry. I have a thick American accent. UA-cam seems to make very good auto captions, so turn that on.
