Dear Dr. Lewin,
Due to these lectures I have finally achieved my dream of becoming a plasma physicist. I just finished my internship at the french tokamak and at ITER and now I am applying for a Phd. You are one among some of the people who transformed my life and I thank you with all my heart.
:)
Congrats and all the best.
Where did you study?
Edupoint suggested me to see ur lecture ..so I came here...really ur explanation is amazing..like it ....love frm India ❤❤❤
love frm USA
Me too

Hello sir I M FROM NIT N INDIA. Sir your lectures make concept easy.
Me also
This website contains all my 94 course lectures (8.01, 8.02 and 8.03) with improved resolution. They also include all my homework problem sets, my exams and the solutions. Also included are lecture notes and 143 short videos in which I discuss basic problems.
ENJOY!
+Lectures by Walter Lewin. They will make you ♥ Physics.
Professor Lewin, I never liked the way my school teachers taught me. I've always believed in self studies. Which made me believe that I have a certain potential in the field of research.
After I've come across your lectures, I believe you are the right person who can guide me comfortably to this.
It is a great feeling. :)
+Lectures by Walter Lewin. They will make you ♥ Physics.
Your work is a piece of Art.
Physics is not an easy to understand topic, but you manage to make it fun and understandable. Watching your lectures have made a huge difference and helped me work my way through my year of physics! Thank you, you are one of the best instructors I have come across!

All my respect prof.
Dr. Lewin,
Thank you so much for putting these lecture videos together. You are an inspiration to young physicists the world over. At least you are to me, sir.
+James Dufour Thank you James
I gotta admit it, these lectures are just a golden ore of information, they helped me understand more things then I could do on my own in 2 years. Also, they are the embodiment of how physics should be done.
Yes. It’s good to know that 31251 says that cosmology can count on their eyes
8:11 when he said special relativity....i thought he is not going to explain it but when he said that he'll touch upon that topic i was like -"thank god....for the least there is someone who thinks out of the course"!... great job sir!

I wish I would have had such brilliant teachers when I did my physics courses at university. Thank you very much to open up your lectures on this platform to a wide audience.
The last part was mesmerising Professor! Thank you so much for your lectures :)
I started craving for the lectures, ever since I got started... I can't help sneaking though a couple of those even during office hours... :)
:)
Your lectures are amazing! I've been self-studying (won't be in college until fall) and your lectures are truly inspiring. Lately I've gotten where I want to actually *see* the physics I'm learning about, and not just all the equations (although I do love the math behind it) and your lectures satisfy that need perfectly! I plan on pursuing a doctorate in physics (even though it's way down the road), and I hope I can become even half as good as you in inspiring students!
Sir you are THE BEST TEACHER I've ever seen. Nobody ever will be able to teach physics like you.
:)
Cloud chambers are so fascinating, as well as the explanations given by the genius Dr Lewin!
You are the best physics professor I have ever seen...
Arnab Mallick Thank you!
Cyclotron at 20:50 (for my reference)
Thanks
This lecture really hit some emotional heartstrings for physics inside of me. I really appreciate this.
Watching this because my physics lectures are online and they are boring without experiments. I love that you do them in every single lectures. Thanks, Professor!
The "Flashforward" was amazing. Thanks for that! It gives Physics a sense of exploration and discovery, quite an awesome feeling.
I wish I could have live lectures from you. You are my inspiration sir after listening to your lectures I decided to study physics. I have no words to say about your lectures. Your lectures are gift from God. Respect from Pakistan.
i get confidence for exams after watching your lectures...thank u very much!!
Your explanation is outstanding... Thanks to you and edupoint !!!!!!
Thank you so much for helping me understand.
Nice to know there are still some good teachers
Sir, You are just too amazing
You made physics more adorable than it was before for me .
You are such an inspiration to the youths .lots of love to you sir ..god bless you ♥️
Thank you sir. it is really enjoyable. here I can study and at the same time can verify experimentally ,
again thank you very much sir for your contribution for students and physics.
My teacher always marvels at my knowledge in the topics
I wish I found this earlier
Thank you and love from Nigeria
You are very welcome
That's really a new world to naive ones like me.
These lectures of Prof. Lewin from 2002 are still magnificent in 2024.❤
Sir your lectures are extremely incredible and it make me to learn physics more deeply
Dear Professor,
Ever since I started watching your lectures I have developed the habit of looking through equations. It has created a tremendous development in the way I think and teach physics. I request you to make dedicated lectures in theory of relativity.
Love from Chennai( India)
thank you very much sir ,
I found physics little difficult but when I come to your lectures it became very easy for me .
really sir you are the best physics teacher who clears the concepts so clearly & nicely,
thank you very very much .
sir you are an amazing personality.
hats off to you
:)
Wooow sir! This is literally the best physics video I have ever seen and this increased my respect to the beauty of physics 💙💚💜.. Thanks a lot sir.. Wishing you good health
Thank you! All my 94 MIT course lectures are on this channel.
Beautiful with practicality I your explanation makes my mind think beyond the boundaries 🎉 thank you so much for this wonderful lecture sir🙏 love from Tibet
I would like to thanks for your incredible work for entire world!
This is not a lecture Its a Masterpiece , sir it your best lecture ive seen thank you from the bottom of my heart
It's my pleasure
loved it..such a great mix of qualitative and quantitative physics..
:)
Like love and respect from India professor. From my opinion you deserve NOBEL PRIZE.
This lecture was great, thank you. And I always love cloud chamber demonstrations! [golf clap]
I really wish I could meet you. You are amazing sir! ☺️❤️
It's always interesting to compare the predictions made in the past with the actual progression of events.
can’t believe this was filmed in 2002, this is a timeless piece of art.
Another amazing lecture! I always learn something new!
Glad you enjoyed it!
thank you profesor for this wonderful lecture !
Ur lectures are best on TH-cam love from India
I wish i had a physics professor like him in my school 😪
This helped me a real lot sir this course makes me potential that i can crack my neet exam luv from TAMILNADU💜 INDIA

Most welcome
I will be happy if you come and teach physics in our school in India
Because your videos motivating me to learn Physics
-Student of Walter Lewin sir from India🇮🇳
33.02 can't miss. Its old news now. But for him to add that is truly a gold of a gesture
I live in India I am 17 years old studying in 12th standard it helped me a lot to prepare me for my board exams thanks after my school I definitely be going to be an engineer and I hope soon I will come to USA as they teachers like him to teach us.
Good luck with you application to a University in the US.
thank you so much sir, for this lectures specially the cyclotron part was quiet interesting.....
You are most welcome
certainly the best person on physics explanation is you.
I tried for mit to explore the world range of physics but the present US policy for forgein student really doesn't seems to be inviting us.
so, with all due respects i would like to ask for the links to connect all lectures given by you.
sir, without a doubt.
here is the link

This is beautiful. I studied philosophy at UCLA and now almost 10 years later I’m learning physics. This lecture series is perfect because you throughly explain the theory and almost more importantly make it real with demonstrations. It’s kind of sad that with all this knowledge (free MIT lectures) general knowledge seems to be regressing into a world of conspiracy theories and nonsense. I do think the traditional lecture format, as powerful as it is, will soon be replaced by other forms of teaching like the channel Physics by Eugene... anyway, for now a proper lecture series hits the spot for me :)
This is from 2002 ? I cant belive it still gold💜
yup 2002
My favourit lecture .
Hello sir 🙂 I'm from India 🇮🇳😀
TodayI studied it in my physics book 📖🙃🙂and curiosity brought me here..!!!!
Love from deep of my heart ❤and from India
Great 👍
Love from INDIA sir....
The final Demonstration is mind blowing. We were looking at actual radiation. Real particles. My mind is blown.
Dr. Lewin thank you so much for uploading the videos and making physics interesting .Professor can you please upload any video on linear particle accelerator and synchrotron like cyclotron ? thanks once again .
:)
Regarding the cyclotron, I'm confused about how the protons can enter and exit the dees, seeing as they are made of metal conductors. How do protons enter and exit a solid?
Thank you for your lecture sir. Great. Can you list out few of your favourite physics books?
For the Love of Physics and the Feynman Lectures.
wow I was just at Fermilab and I saw this in the video. Some quite amazing discoveries (including the Higgs Boson) since this video was made!
Also were you talking about the Fermilab experiment that discovered the top quark?
Great that you were there! >>>>the Fermilab experiment that discovered the top quark?>>> yup! The Higgs was discovered by the LHC.
You are great sir
Professor Lewin ; an offbeat question.. what's written on your badge ? also ive noticed that in every lecture you wear a unique badge , why do you wear them ? I like your style :D
InventTwig I have about 50 broaches and I almost always wear one during my lectures for freshmen. They like it and so do I.
Lectures by Walter Lewin. They will make you ♥ Physics. They are all food related i think. I saw a coffee cup, an egg omelet also a cookie etc
Nice lecture sir ,love 💕 from India🇳🇪
You mean 🇮🇳
Sir why do charge particles experience force at all from magnetic field.Is it a fundamental property of magnetic field?😁😁😁too fundamental question but plzzzz ans
has he ever covered thermodynamics in his lectures ?
Just curious, are the breaks in the file due to the radioactivity?
This was a long time ago 32:50 how many eV have we gotten to today? What is the highest number of eV we have ever reached?
All i can say for prof. Walter lewin is thank u sir. Everytime when i used to get bored in my classroom i always miss some lectures but i didnt have any tension because i have Prof Lewin with me. Thank u sir.
:)
Sir i need ur study material. Is there any way of getting that.

Lectures by Walter Lewin. They will make you ♥ Physics. Can i have your email. I have a question regarding cyclotron.
15 thousand viewers have asked for my email during the past 3 years. It's strictly private. You can ask your question here on my TH-cam channel.
Love you Sir
Dear Prof. Walter Lewin, Where can I find videos on rest of the topics, not covered in 8.01 and 8.02 video lectures ,
I am appearing in GRE physics after two months. It would be very helpful, if I find it as videos lectures.
Dear Professor,
What is the trajectory of a proton moving across the B field with an increasing velocity v=vo+at?
F=q(E+vXB) Google LHC
Hi Walter, I enjoyed the lecture. I'm doing a review of C14 and I will be looking for materials to illustrate cosmic rays and their reactions. I recall someone was sending up cloud chambers in the 1930's to measure them. Also, what are Neutron detectors like? (Barry Marshall NL Med 2005).
use google - ilt's all there
Professor I have a question... We say when electric current flows through a spring it compresses because of attraction due to magnetic force ... But why do we ignore the fact that there has to be some electrostatic repulsion between the electrons flowing in the spring... As since we know electrostatic repulsion is far greater than magnetic attraction in this case... The string should rather elongate... ( This question was asked in jee and I had a doubt in the answer... The answer was that spring would compress when current flows through it)
Very intuitive lecture
Glad you think so!
Love from india sir♥
Sir! Please provide a link to download physics notes.
Thanku❤️
Sir and for changing the frequency of the cylclotron twice each, do we do it manually or is there any other mechanism?
how long does it take for the charge to go around? that will give you your answer. In one rotation the field has to change direction twice.
Love from India......
prof
is the formula of gamma which you gave, is also the formula of time dilation ?
Lorentz contraction gamma is 1/sqrt[1-(v/c)^2] it's all over SR also in time dilation.
Awesome👍
In which lecture is it that you distorted a tv image?

Very good 🙏🙏🙏🙏🙏🙏
Dear professor the charge q is in absolute value? My question comes because, supposedly the charge of the eléctron is negative.
Thank you teacher. :D
In all equations q is sign sensitive. The force F on charge q, F= qE. If q is + then F is in the same direction as E if q is negative then F it is in the opposite direction of E.
