Dear Prof. Walter Lewin Sir, I wanted to take a moment to express my gratitude for the incredible impact your KZbin videos have had on me. Your passion for your subject and your ability to make even the most complex topics understandable have been invaluable to my learning journey. Thank you for sharing your knowledge and inspiring me to pursue my own academic interests. Sincerely, Amit Yadav Love ❤ from India 🇮🇳

​@@lecturesbywalterlewin.they9259 Sir. Would you be kind enough to clarify why condensation occurs over the upper wing of airliners as they land in humid air. My understanding is that it is due to Adiabatic Cooling where the air hits the low pressure on the upper wing and expands rapidly. In doing so the volume increases and there is work done and a drop in temperature to dew point condensation. Is this correct? Thanks

If you can afford it, of course, I am willing to send you a signed copy of my book with *a special note for you + a signed picture of me, which will also have your name on it,* but the price is high as I pay 30% tax here in the US of your payment. Postage for me is also high (e.g., India $35). Ofcoz the book that I send you contains the photo index. Your total costs for 1 paperback copy: US $40; Europe, South America, Brazil, Canada, Pakistan, Nepal, Bangladesh Tanzania & India $65; Middle East & Asia: Japan, Philippines, China, Thailand & Australia $80. I make zero money on these sales, I sell them for what they cost me. You should transfer the money to my PayPal account (see below). *Since we are friends, please mark "family and friends", PayPal will then not charge me a 5% fee* and please let me also know in PayPal your name and complete address and *which name I should use for my note in your book and on my picture.* *For those of you who only want a signed copy of the picture of me, swinging from the pendulum,* with your name on it as well, it will cost you *$10 for 1 copy* (that includes postage). It's the same price for all countries. *You should send me on PayPal your complete address and the name you want me to write on the picture.* Please transfer the $12 to *my PayPal account which is* [e-mail]. *Keep in mind that you must first enter PayPal and then my account.*

Dear Professor Walter Lewin I really appreciate what you have done and want good things happen to you. I recommend you to take shahadah-accept that there is no one worthy worship besides Allah and He is only one and true God, and Muhammad (peace be upon him) is his messenger. After you revert to Islam, your all previous sins will be forgiven and your good deeds will stay with you. I want to help you to reach paradise, Jannah. You already know that Buddha is not god and does not control anything-the statue cannot even help himself if you throw it in water, and there is only one much much powerful God and his name is Allah.
