Hello professor Lewin. I’ve been watching your videos since i was still in highschool and i can confidently say i have always loved seeing something new about physics and that is how i started being interested in it. I studied physics at my highschool and i have just begun studying it at my dream university. I wanted to directly thank you for inspiring me to accept challenges and be ready for them and because of you and your videos i never gave up and i became what i am today. All i wanted with this comment is to show you my respect professor and tell you that trough my schooling and later on university i have met many other ones who are as thankful for your work and admire you as much. There is really no such a word i can think of that can explain my gratefulness towards everything you have done.
Dear professor, I'm looking forward to your next video, are you interested in discussing the energy of a rocket in flight, I'm very curious about the energy conversion in this case, I think it's a good question for people who study physics, for example, how much energy is released by fuel, how much energy is converted into kinetic energy of gas, etc., I'm still taking the 8.01 course but I'm having trouble analyzing the model of rocket mechanics, I hope we can discuss this together, and finally thank you for sharing the beauty of physics with us, you are Newton and Einstein in my heart❤
Sir, in the solution they have compared the total binding energies. I have another way, I don't know if the logic is correct or not. Since He3 has a binding energy per nucleon lower than that of Be7, it is less stable than Be7. Therefore the reaction will not be feasible due to formation of a less stable nuclei. Is the feasibility of the reaction dependent on both of the nuclei or can we decide it if even one of the nuclei is less stable than the reactant? Please tell.
Hey Prof. I have a question. In part (c) can't the reaction take place if we supply the system with energy through accelerating the Be atom (kinetic energy)?
Its interesting how, with these problem-videos, you are creating an environment similar to a classroom-engaging with the comments as if they are the pupils attending it. But please temper your expectations to avoid disappointment, should you find that the viewership and/or (the quality of) engagement in these videos decline. Such is the volatile nature of posting to social media.
Sir I z a class 10 student I don't know about this problem but I am truly passionate about physics for that you are the reason

thanks for your kind words
I love your lectures these helps a lot in my BS courses
The best support to all students!!
Hearty Wishes from India sir
You are so great Sir

I cover rockets in detail in one of my 8.01 lectures. *WATCH IT*
@LecturesbyWalterlewin Does sir has channel or something where he can share academic resources, Physics research papers and insights..?
no that does not exist on my channel
Thank you for 8.0x lectures sir
It's my pleasure
So energetic voice!!
So great Sir
Good bye nuclear physics, hello hello newtonian mechanics. I'm a bit sad, but also curious what the next problem will be...
Sir, in the solution they have compared the total binding energies. I have another way, I don't know if the logic is correct or not.

Hey sir I’m always a big fan of you hope you recognise me . Lots of love from ind❤❤
Hey Prof. I have a question. In part (c) can't the reaction take place if we supply the system with energy through accelerating the Be atom (kinetic energy)?
yes in principle it can happen if a large amount of energy were added to compendate for the decrease in Binding Energy
Are there any highs particles in sound waves
qujestion unclear, ask Quora
❤❤❤
Sir from Pakistan
Hello professor

thank you
I want to talk with you Mentor.
1.3 million of my 1.7 million subscribers want to talk to me. I cannot do it.

Sir please reply to my comment ❤️🧡💖 ur my passion
