Namaste Sir, I am from India, I am grateful for the lessons you've taught me, in CZcams. Thank you for your guidance. You are the kind of teacher that every student dreams of having.
Sir, you are great. My teacher recommends your lecture videos for me to correctly visualize Physics. Now also, I am preparing for JEE as you told (by watching your lectures). All the thanks, I owe to you....
Hallo Prof. Lewin, leuk dat u weer eens in Nederland bent. Ik woon in Belgie en ben 72 jaar. Ik volg nog altijd uw video's met fysica problemen. Ik was 1 van de 10 met de juiste oplossing van probleem 200. Ik wens U en uw vrouw nog een aangenaam verblijf in Nederland.
woah.. this is so cool. I wonder if any way i’m related to you, I have the same last name. It’d be cool to know loving types of physics (and perhaps space/astronomy) runs from time to time in the family… I’ll be sure to watch your videos sometimes :).
Sir I m from indian.. ........You are the G. O. A. T of physics in all over the world ❤❤❤..... Sir I have a question..... Could you meet me???😢.... I m big fan of you....
@@lecturesbywalterlewin.they9259 Sir, I cannot come due to some reason. Sir, will you never come to India? Sir, I have a request, Sir, please come and meet the founder of Physics Wallah (Alakh Pandey Sir)... Sir, many students will come to meet you and will get some study related information...
@@Gilmaan-malik I have been 4 times in India. My last time was 6 weeks in 2014 when I gave 8 lectures in India. Given my age and the air polution in India, my medical staff does not want me to go again to India.
Even I want to meet you professor I am also from India Isn't there any online way or any other easier way to meet you I am very big fan of you since I saw your video and fell on love with physics and want to become a physics professor like you.
Well, I found out that I understood the physics (the easy part) so that my numerical approximation in Excel was correct, but on the other hand my calculus is really rusty, so I did not figure out the integral! So, I feel I should not be listed as solving it, because I did not get part A.
Hello sir I hope you are doing well Just wanted an advice I love physics and maths but idk chemistry is something which looks like a messy room What should i do I have just started 10th and have covered little bit of 11 and 12th topics of physics and maths which i found interesting Like vectors, models of atom and loved all the phenomena's associated with light diffraction, polarisation etc .. i have even attended your mit lectures
One of my favorite parts about this problem was that it really challenged not only the maths side, but physics as well. My initial attempt tried utilizing kinematic relations, but alas, it wasn’t constant acceleration! It took me a bit to reason through the problem until I finally got the correct setup and math. Thank you for a fun problem, can’t wait for the next.
I am getting trouble in understanding chemistry since it come i can't understand anything in chemistry i just have to memorise everything so much headache...
Today My lit teacher asked me to write a book as an event. I am thinking of writing about human life and proposing my opinions on various topic like suffering,failure detachment. What do you think about writing a book keeping in mind that I am just 16? Wish you good health sir Lewin.
Is it possible for us to imagine how light comes from the sun how does it actually look like bcz as it is a sphere , light is being emitted at each point and how can it have different wavelengths and different colours.. why only 7 colours I am not able to explain my question but if you got any idea what is my doubt plz answer i have been figuring it out since 6 months but .....
*NOT ONLY 7 colors* google "blackbody radiation form the sun" The Sun, with an effective temperature of approximately 5800 K, is an approximate black body with an emission spectrum peaked in the central, yellow-green part of the visible spectrum, but with significant power in the ultraviolet as well.
You are genius sir... I'll do my PhD from IIT Delhi And whole life dedicate to physics (in nowadays i read some good physics books like rasnik Halliday, university physics, the Feynman lectures and for the love of physics ) they help me to become my dream come True
How I approached this problem was to use the equation of variation in gravity due to height and ended up with a similar equation but not exactly the same. Can this problem be solved by this approach.
What answer did you get? If it was obviously wrong then so be it & you can write it off as a mistake. I provided a different answer and made no mistake in my final answer as far as I know... Never say never. Even professors can be wrong frequently. Mathematics can also be wrong (sometimes).
Today at sunrise time i saw few rainbow colours in the sky but with no rain drops , clear sky and with few clouds infront of the sun But colours are a result of scattering of light through rain drops

I really love your videos! I recently had a massive science exam which included physics. Hopefully I get good grades!
I hope so too!
Sir your lectures have made me love physics❤
Glad to hear that
I love physics too, if I could understand it!😃

Only 21 days left for jee adv❤
So what
Advanced army is here
As a 8th grader, I wish you for a great exam bhaiya
Have u qualified mains
If Walter Lewin sir like and comment on my comment I will gave my all life to physics and research ❤

Sir in that solar eclipse video ..when the video ended there was a flash of light something like that, what was that
refelection of nearby light
I eagerly waited for the solution.

I wanna became my physics like you
That is begun from May i but now i can and i will

if you did not find that the answer to question b) was 87 hr - then your approach was wrong
Yes I know I was wrong but can this problem be solved in that way?
Hello sir I am under graduate student in Physics from Paky
I want to study abroad in your country on student scholarship.Can you help in it.❤❤

Sir , I got wrong in this question . omg!! . I feel bad for me.😪😪😣😣😥😥😥😥😥😥😭😭😭😭. I'm so sad right now.
Don't feel bad or sad. Try to understand where you went wrong. Then you will have learnt something and you can feel good.

Sir I am from India, and I am preparing for IIT JEE exam, is it worth qualifying that exam Sir, are IITs good?
ask your teachers
Today at sunrise time i saw few rainbow colours in the sky but with no rain drops , clear sky and with few clouds infront of the sun
But colours are a result of scattering of light through rain drops
>>>>>>But colours are a result of scattering of light through rain drops>>>> *incorrect*
Sorry .. dispersion
But still we need water molecules?
@@studytosuccess6501 *wrong again* *just water molecules is not enough - *we need water drops*
Ok sorry again ...but then what is the reason of what I saw ..
@@studytosuccess6501 you did not see a rainbow. Where in the sky did you see the colors? how far away (angle in degrees) from the sun?
