Beautifully explained. I have my Classical Mechanics exam tomorrow. If I ace it, I will give you the credits because my teacher is not responding to my messages. Thank you.
Well, there was a question to draw a graph of a function and it higher powers. I went into infinity mode. Couldnt get out of the loop. Anyway, I aced the exam of Mathematical Methods for Physicists without much effort at all.
Hi i like your videos . Can you please make video on lagrangian , hamiltonian and thier derivation covering all topics(d alemberts priciple, euler's equation).
no - the 3 values on the right are not all the same. If you chose specific values for i and k and try it out, you'd get 1 if i and k are the same, and 0 if i and k are different. That matches the result you'd get from the summation property: delta(ij)delta(jk) = delta(ik)
I like your videos, but the Einstein summation convention is not used like that. You need one covariant index and one contravariant index. Which becomes important when you go to general and special relativity.
Yes, you are completely right. I didn't want to complicate the topic with covariant and contravariant indices. The Einstein summation works just fine for doubly occurring indices, placed no matter how: on top, on the bottom, on the left, on the right or upside down. 😃

This is the best explanation, I didn't understand anything in my 90 minutes course of university but in 10 minutes i totally got it. Thanks 🙏
nice! Thank you for your feedback! :)
Appreciate this, this 10 minute video clip is way more better than a 90 minute lecture in college
Thank your very much!
❤
Wow. As a German engineering Student i did understand more in this video, than i did, listening to hours of lecture
You are such a great teacher, one of a kind.
Ausgezeichnet !
Thank you very much!
good intuitive explanation with nice visuals, thanks man
Thank you very much!

I love your videos!! Keep the good work, you have one of the best real science channels in RUclips
Thank you very much!
Excellent instruction - well presented - complete/concise. Excellent. Thank You.
this is just a fancy '1'
Love this graphically clear explanation, thank you for putting in so much work
Thank you for your feedback, shashank! 🙂
감사합니다! Learned the basics of tensor from your lectures. it really helped
Thank you! Glad to hear it!
Nice and clear explanation 👏
Thank you!
Guy took 10 minutes what my professor took weeks to explain. Thanks a lot.
Hehe, I feel you 😅
Love you sir for this video 🤩🤩 i🙏🙏🙏
thanks
THANK YOU !
Thank you so much for your explanation!
Thank you for watching! Check out my physics website: en.universaldenker.org :)
Nice video and very helpful and clean editing.
Thank you very much!

Thank you! I wish you good luck tomorrow with the exam
@@fufaev-alexander I will not disappoint you!

Thanks bro!
Hey Matheus, thank you too for the comment!
Keep up the great work....
Thank you very much!
Thank you so much!!!
You're welcome, tee
Danke!
Ist das der Anfang einer Serie?
Sir how to prove rule2 properly?
Great video 📷📸 thank you
Brilliant!
Thank you very much!
Great methodology
Thank you very much!
You got a new subscriber ❤️😁
Thank you!
damn, this cleared everything!!!!!!!!!!!!!!!
Thank you very much!
Is it possible to make a video on variational calculus that we use at multiple places, e.g to get equation of motion and all?
Vielen Dank
Thank you!
Can you do a video on tensor calculus
I want to learn the "radical physics"
Hi i like your videos . Can you please make video on lagrangian , hamiltonian and thier derivation covering all topics(d alemberts priciple, euler's equation).
Please explain why the rules came so instead of just stating them.
Check out my lesson:

2:05 isn't it supposed to be 3*delta(ij) delta(jk) bexlcause thezly are added on the right side?
no - the 3 values on the right are not all the same. If you chose specific values for i and k and try it out, you'd get 1 if i and k are the same, and 0 if i and k are different. That matches the result you'd get from the summation property: delta(ij)delta(jk) = delta(ik)
Is kroneker delta on isotropic tensor

Imagine a 50D vector. :D :D
👌👌
