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.
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. :)
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!
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.
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.
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!
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.
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 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.
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!
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 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
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)
Hello sir I am from India , after watching this lecture and many more i have really now started looking beyond equation ..really love the way you teach physics ...!!!
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.
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.
Really appreciated lectures by you sir 😄 You really made me to love 😍😍 with PHYSICS. Im from INDIA,i too have shared your lectures to my couple of friends. My love 😍 to you and your physics from INDIA.

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
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 :)
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🇮🇳
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?
why they(CERN) declared the mass in GeV.. not in kg or other standard units for higgs boson...energy and mass are equivalent ..E=M*C^2...but why is in energy terms???is there a specific reason?
In nuclear and atomic physics we use eV as the unit of energy (it's 1.6*10^(-19) J. to get the mass you would have to change to Joules and then divide by c^2. No physicist thinks that way. For me a proton has a mass of about 1 GeV and an electron 511 keV.
+Lectures by Walter Lewin. They will make you ♥ Physics. thank you for helping me out....I really appreciate that you reply to me among the large number of students you have....really grateful....I am looking forward to see you....
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.
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
B has to be increased as the proton emerges from the gap in which it is accelerated. If the B field goes to zero during the short time that they spend in the gap, then the protons will cross over in a straight line. Ask google what the B-field is when the protons are in the gap.
I DID NOT tell you that. Read my answer again. I wrote >>> If the B field goes to zero during the short time that they spend in the gap,>>> When the protons have reached their maximum energy they can be tunneled to a target. Of course, there would be NO B-field in that tunnel. In most cases, the target is inside the cyclotron, in which case there is no tunnel. - ask google.
Thank you so much sir for this amazing lecture. I am preparing for a competitive exam and I am facing difficulties in solving numericals. But now after watching your lectures I am able to solve numericals and I really fall in love ❤ with Physics and this all is possible just because of you. I am going to watch your all lectures.

43:28...the bubble chamber showing both positron and electron creating spiral pattern of ions through liq. hydrogen,if they have same mass then they will have the same spiral structure,but the right spiral structure seems larger than the left.....why is that???
Some physics books call q*VXB the Lorentz force, others call qE + q*VXB the Lorentz force. At my University (many decades ago, only q*VXB was called the Lorentz force. A name is not so important as long as there is no misunderstanding about the difference between the two.
The gravitational force by the sun on the Earth is perpendicular to the Earth' velocity. Thus that force does NO work. Therefore its speed will not change but its direction will change. F=q*VXB sane thing! F is always perpendicular to V.
It's incredible how easily American citizens say this: "Atomic bombs were dropped on two cities and the second world war was over". When I heard this for the first time from my American teacher of English I was shocked... Still shocked hearing this from the professor. Something is wrong with this world if so brilliant and knowledgeable people can be at ease with such diabolic action.
alpha particles leave a VERY dense and short track because of their high charge and high mass. Electrons leave a thin long track - lower charge and much lower mass. The electron tracks look like a spider web
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
Professor, at 13:44 I believe you made a mistake with the forces applied to an electron with velocity. They should be flipped 180 degrees. Not that it truly matters that much :)
sir, I found it why you put different badges on the right of your shirt : to assure more concentration on your interesting lectures than on those badges

Isn't Lorentz force the sum of the electric force and magnetic force
