I love your explanation Professor. you helped me to find out that i really love physics. Thanks for sharing these videos.

[InventTwig]

Yay !! got it correct. It's getting exciting !! Can't wait.

[camolita]

Lovely Science and its enormous need not only to acquire new but also to transmit its knowledge.

[federico]

Profesor your lectures are awesome!! they're helping me through my physics course, greetings from Argentina! ☺

[neozxa]

why do i love science in general so much when im bingewatching science videos on youtube

then when i have to cram for exams i start to hate it again

[ritikgarg]

Your videos are awesome, sir! Thankyou for these videos.

Awesome video!
congratulations on the 100K subs

Greetings to the best professor that ever lived! I just want to congratulate you on your 100K subscribers. I also wanted to ask you something: I am someone who adores math and physics, and I don't just see them as something academic, physics is my life. In high school, I perform averagely in physics (about 75/100), while at home, I am reading, solving, learning, and most important, thinking about physics at a university level. My teacher says that it is because of my work habits. In class, I find everything too simple, and when I study for the exams... It is also too simple. E.g: Yesterday, I wanted to see how much I knew about the lesson before studying. I wrote everything I knew on my notebook... but I noticed that I wrote the entire lesson! I did the quiz today and got a 60%. What can be the reason I am getting average grades when I find it easy and I am doing more advanced topics? What can I do to increase my grades?

BTW: This was an amazing problem! Keep up the good work!

Congratulations professor on 100k! Well deserved!
I'm having issues considering solving problems involving emf and so, any advice?
Do you give online lectures? Like skype?
Thank you!

Hello mr Walter Lewin can you please tell me why an amplifier can reject certain frequency by performing convulution by stacking and scaling how does it happen is it due to inductor or capacitor inside op amplifier

[MrKatana]

However, you are assuming here, that the radius of the rod is negligible, right? Otherwise the moment of inertia would contain antoher term which would look like (Mr^2)/4 because the rod is in fact a cylinder rotating around its end. It's perfectly alright to do so because the radius is almost nothing compared to the lenght of the rod - it is negligible.

Professor really aweosome video.Can you tell me is Irodov Fundamental laws mechanics & basic laws of the electromagnetism good for physics olympiad

[Dynamicblingbling]

Professor Lewin, I am studying for my high school physics. Do you have any advice for me?

[hseverins]

Bijna hetzelfde! 😂😂😂😂😂😂. Lieve walter, je hebt me doen duizelen! Op zn plat gezegd, snap er geen klote meer van haha

[hansonyuen]

yay! i have passed this course again !

[sriauphy]

I love your videos very much sir.
Its very interesting.
But I can't understood in taking uncertainty & in calculations of uncertainty.

[RahulKumar-quwi]

But Professor, this is the same answer I got at my second attempt after you told my first one was incorrect... You told me even this answer of mine is incorrect... Why?
