  I wait eagerly for him to say ,'So first I want to demonstrate to you....'

  This really belongs to &nbsp;the positive sides of internet, I can attend &nbsp;classes from MIT from my home in Sweden for free.<br>Let&apos;s forget about all the downsides of internet, at least for now.

  I start getting why the MIT is so prestigeous. Professors like you are capable of perfectly explaining something to the students without confusing them. I am currently studying electrical engineering at the Technical University in Vienna and here are the students the ones, that have to understand stuff out of books instead of listening of such great lectures. i guess everyone has it a bit different and their way of learning may vary, but the finishing pount is the same for everyone. thank you for sharing your knowledge in your unique way.

  I started studying physics to clear IITJEE but ended up falling in love with it

  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. <br>ENJOY!

  I was practicing for my Sat physics subject test, which in taking because it&apos;s an MIT entrance requirement. I didn&apos;t know an answer about emf and current, but started thinking and heard Walter&apos;s voice talking me through it, and figured it out. These lectures did make me &lt;3 physics, thank you professor Lewin.

  Sir, at first &nbsp;I was very afraid about <a href="https://www.youtube.com/hashtag/physics">#Physics</a> but now a days after watching your lectures &nbsp;, &nbsp;I can feel that physics is a theoretical and interesting subject. Thank you Sir. Love from &nbsp;# India... 🇮🇳🇮🇳🇮🇳

  I am a retired EE and CS engineer, having gotten my EE degree in the 60s. &nbsp;That being said, I am learning more from your videos, some of which I forgot, some I wasn&apos;t taught and some I never really fully understood. &nbsp;You obviously love your job and do a great job teaching. &nbsp;Right now, I am watching your videos selectively to get a better grasp of EM wave propagation, transmission lines and antennas. &nbsp;Thank you for posting these classes Professor Lewin! &nbsp;By the way, you probably should use less salt on your eggs. &nbsp;I know I have to. :-)<br>I wonder what would happen if you poured some Gatorade into the distilled water. &nbsp;I think the answer is easy. &nbsp;I have to avoid the stuff because of the salt content.

  Woooow mind blowing , man I love the way you teach in, where you connect everything together to help us understand feel the physics not memorize it !!! Thank you 👏👏👏
