@@lecturesbywalterlewin.they9259 sir should I give importantance to jee exam in class 11 or my boards of class 12.
@@lecturesbywalterlewin.they9259 Which playlist will you suggest for Physics/ Astronomy for those of us who have already taken 8.01 and 8.02 ?
@@sachitvarshney1495 mit has a playlist for cosmology tho
its a nice experience to listen to dr. Walter .your padagogy is amazing.
It's amazing how everyone just gets up and just leaves at the end of the lecture. He honestly deserves a round of applause, because that was brilliant!
the assignments for the lecture are not easy and at least a full night's work. So no applause. There would be one if there were no assignments though!
This is MIT, not nursery school!
nerd!
@@iamok2009 You guys should be grateful to him. In my university, teachers don't even bother to do practical examples, just theory. And of course, we don't use laboratories for the whole 3 years.
@@lecturesbywalterlewin.they9259 always with u professor
This teacher is so good that in 50 min I gained more understanding than in weeks at my university. Till now I was just crunching the numbers and getting results, now I look at a formula and immediately have an insight at what's going on. He is simply awesome!
Thanks for your kind words
I have been studying physics at one of the oldest universities of the world, one that is very proud of its heritage (doubtfully, as they did court Lenard). But I only remember ONE of all the profs teaching who is faintly comparable to your way of explaining. Most are not even capable to put a headline to a lecture (like »today we talk about speed, velocity, acceleration«) and just start writing dx/dt etc on the blackboard without any reason becoming obvious for the students watching / listening. I can't remember any of my teachers (starting from school) introducing the concept of accuracy with the topic of measuring itself.
So, please do not be that modest. While teaching at my university was aimed at casting out 60% (believing that the remaining 40% would be the elite and not the cheaters), your lectures are targeted to take the whole bus to the destination. My great appreciation for this. And you know that you are a great stage performer, too - big motivation aspect.
I hope that anyone who tries teaching students will watch your videos.
Thanks for your kind words!
Aristotle is better
@@timmy18135 Galileo is better
At this moment in time, when we are forbidden to receive quality education due to unreasonable restrictions, i must say this video lecture is priceless. I spent hours trying to comprehend the concepts of kinematics from many books, yet i learned more from a 50 minute video in a foreign language. Best wishes to those who produced this material.
Bro are sir's lectures beneficial for jee?
@@intellect8444 absolutely. Sir is incredible
@@intellect8444 mhm definitely. I'm a class 11 student this helps a lot and just the best Physics teacher for me.
I am 30 years old now, I am from Argentina. I was wrong when I went to college, I studied something I do not really enjoy now, so I decided to go back to school at my age and start a physics career in my local University. Now I am more mature and I enjoy learning as I enjoy a movie. Science gave my life a purpose, and this lecture is making my trip way easier, I would like to thank you Walter for your passionate and amazing job at teaching us. I cannot be more greatful to be able to see an actual MIT class from my desk back in Argentina, I really appreciate what you are doing here, thanks.
Hola Nicolas,que carrera estudiaste la cual no te gusto?
estudiaras fisica en la UBA?
I studied physics most of my life , I love physics and physical science .I teach for more than 14 years before reaching this wonderful country .i will say that you have my admiration for the way you teach physics that has attracted as this science to many young people .

same with me
Same.
Im in class 11th from INDIA preparing for Jee started watching lectures of Lewin sir
These lectures are really amazing
Thanks Lewin sir❤️
It's my pleasure
Bro I am in class 11 now should I watch his lecture for jee
@@Skarminvestorsyou can go through the lectures for conceptual understanding, and go through some books for question practice for jee. That'll be enough..
Thank you professor. I'm from India. And your lectures helps me a lot in clearing concepts of physics. And it never bores me. Thank you very much.
bro i am also fromm india, are these lectures enough for JEE and Advanced?

after years studying physics in high school most of the material in this video was more or less known but still I felt like pieces of puzzle were only now falling into place, I'm loving these videos!
You are the Best physics teacher sir.
Got to understand concepts more better than ever .
Thankyou
It feels so strange knowing that this lecture was given during a time when they had to develop pictures. Times have changed so much now!
Your lectures are really wonderful, thank you so much for sharing them. I took physics in college because I really enjoyed it but majored in economics which I also enjoy very much. I think if I had had you as a teacher, things would have turned out differently!
Definetely, a perfect teacher that is needed in every university. No one could make me understand physics but with your videos its seems so easy
thank you for this lovely way of teaching great walter lewin
+DABAN 13 You are very welcome!
🙏RESPECT FROM INDIA🙏🇮🇳🇮🇳🇮🇳
I am Watching for IIT JEE Exam ❤️❤️
Watched all your mit lectures about 4-5 year ago. Still visit to watch it again and again. Each one of those are masterpiece. It doesn't just inspire students but teachers all over the globe. In one of those lecture camera turned to a student who was sleeping, literally sleeping. At that time I thought, How can someone sleeps in walter lewin's lecture.
I can’t be more grateful for you prof for all of your lectures❤️
Sir,
With Best Reagards ,
I want to tell you that....
This the the masterpiece since 8 years, I love your experiments very much thanks ❤️
11:03 That moment you ralized Isaac Newtown travels in time to learn physics.
😂😂
lmfao this made me laugh
Prof. EINSTEIN IS TEACHING NEWTONIAN PHYSICS TO SIR ISAAC NEWTON!!!!
May God bless you, Professor Lewin.
You and Physics are synonims.
You are Literally a rockstar for anyone on youtube! You are a Great Teacher!
This video is accurately very useful for 11th std students, the first imp chp in 11th std , thank Walter sir for this videos! Love from india
As a high school English major, I'm astounded that I actually enjoy this enough for me to get into physics
🙏 From India Sir.Start to follow your lectures. Now I see that how dead equations become live. Experiments are amazing.Thank you Professor.🙏
I think the one thing better than having a gift is being able to share a gift. And for that we thank you.
I am looking forward to getting stuck into these lectures, this is far better than any TV series!
:)
I'm preparing for JEE and this is very helpful for me...
Thanks Sir Lewin.
DID U CLEAR
The type of teaching i always dreamt of!
Instantly became your fan sir...that energy which you put in while delivering lectures is awesome...wish I had a chance to be taught by you.
So glad we have access to your lectures!!
just to write out the 100th comment!
Love your videos, professor! Your book, "For the love of physics", was an amazing read!
Glad you enjoyed it!
30.00 to 34.15 beautiful. .....
Sir is absolutely amazing
The way you teach is awesome
I wish I had teachers like you in my country
Here teachers just teach for the shake of scoring not for learning
But your lectures are very intuitive and fun
I love Physics from a very young age (8 years old)
Now I am 17 and starting my first year of Undergraduate Degree in Physics, Chemistry and Maths
And want to be a Physicist in future
So my salute to you for giving these wonderful lectures
Love from Himalayas , India
I'm taking physics in high school to take aerospace engineering in university. Thank you for providing free access to your wonderful lectures!! They are both entertaining and educational :)q
I'm very thankful to you sir for your interesting physics lectures. I'm very curious at the time you say that you are going "TO TEST". Your experiments are wow! There are very few lectures in India that perform practicals wid theory that you do...and I just love your lectures!
Hope you are well and good!😊
This what you call *REAL PRACTICAL KNOWLEDGE*
as a jee aspirant these lectures have helped me a lot not only in cracking tha advanced problems but also in regaining my interest in physics. lots of love from india.
Dear sir, your are great. Your lectures are giving us motivation to win noble.I just want to say that in our universe only few people are born to change it and you are the one. Thankyou so much to change my life.😊😊
I am JEE aspirant and it's really good for Revision sir!!
Thank you sir🙏🙏❤️❤️
Bro is it enough for jee ?
More than sufficient 😅
11:02 Newton invented a time machine, travelled into the future and found out he has sight defects, he ended up wearing glasses. To cover up with the physics that was discovered after his death. He joined Walter Sir's classes, because Walter sir is the best you can get.
I noticed the very same lmao, i was like "oh shit even Newton's in his class"
Newton learn his own topics😂😂
😂
I already know everything that is taught in this video, but still I watched it all because he explains so well and with so much enthusiasm :)
Needless to say, he is probably the greatest & most energetic professor of Physics in the world today !
Amazing man really helping through my 11th and 12th
:)
I regret the time I wasted watching celebrities instead of these.
Same
True
@@advaith7413 ereh
@Isaac Newton And apples I presume, he would've told you everything u needed to know.
Newton's apple IS the most widely known of all celebrities. Any others are so time constrained that only a small proportion of the populace ever knew them - perhaps barring Hank VIII and his wives' heads in baskets, as they were all 100 years older than Ike...
Sir, you taught them many years ago and this TH-cam never brought them in my recommendations when I was scrolling down. I wish I had more time :(
Thank you sir for such wonderful lectures.
Thank you Walter, good health to you and your family
Sir I'm from India 🇮🇳 and preparing for JEE Advanced Exam. I watch your lectures for clearing my concepts.:)
Thanks for uploading:)
Have you cracked
Did you qualify ??? I'm an aspirant and I'd like to know if you did.
Love the lectures btw, very helpful indeed.
These lectures can clear your basics but not help you in cracking JEE Advanced.
I came here because of youtube recommended and ended up watching the whole video. What a great teacher!
the best physics teacher more energitic and enthousiastic. i begin to love physics because of you sir and your lovely book for the love of physics. thank you

Thank you sir for your video I just loved it
From India
This man is an absolute genius. Love the passion he puts in
:)
I always thought physics to be a subject way out of my league, hence mugged up max formulas of it, sir, I'll remain eternally grateful to you for teaching me how relevant it is to delve into this subject, not only to prepare for an entrance but also to explore the massive wonders of this Universe and Beyond! Lots of Respect Sir

Today is special day for teachers in India... Professor I found ur channel today.. Happy Teacher's Day..
11:02 Even newton's son is attending your classes!
it's not his son, it's his great great great gandchild
@KESHAV There is no record of Newton having children. He must be Newton's great great great grandchild in spirit. Maybe Newton inspired his appearance.
Just to proof I'm studying :p , did someone saw that in 25:33 he forgot a "2" in dt?! Of course he corrected the mistake later in red!
yup
At the time 26.07 min in this video equation shown for acceleration as 2nd derivative of velocity and time is missing "SQR"for the time. Minor mistake/typo while professor was presenting it. On the second line for acceleration equation was added.
Fantastic lectures ... Bravo
Didn't skip the ads, Prof. really deserves that extra bit of money.
11:03
You know how good he is when ya see Newton travelling more than 3 centuries in future just to attend his lectures
Best comment ever.
11:07 - I was expecting him to say "i need a volunteer".
You are a boss, Walter. Greetings from Australia!
sir i am really impressed by the way you teach and infact i just love your lectures
sir tell me that what makes one to love physics
An anecdote from my life : " When I was 8 I first read the story of Newton's apple and I wanted to verify the truth I went to my backyard took a coconut and throeght on the air on a table of crystal i had a good scolding but mark my life i my love for physics
great story
by the way, it's not clear that the apple story of Newton is accurate, but it's a nice story anyhow.
I am so happy you did this. I can follow my own professor, but he seems to leave certain things out that keeps coming up in the homework. Thanks a lot for this. Just a quick question, what math was required to take this class. I assume at least basic calculus with derivatives, but was integral calculus required as well?
YES that's also required.
Thanks for letting me know.
Nicholi Martin i think it's just a basic integration rule you need that's it
Thankyou sir for clearing all my doubts regarding circular motion.Although tomorrow is my exam!!!You gave me a good revision of this chapter!!!😀From-🇮🇳
I am greeting from Somalia. Although I am biology and chemistry teacher, I like how he teaches physics. Go forward excellent physics professor.
Hello professor Lewin! I am wondering if you could give me the ISBN code for the book you used for this course? I find your lectures extremely helpful and the book that I have for Physics II for your course is great as well. Just want to complete my collection.
Thanks

i wish i couldve a teacher like you.......!
Thank you so much sir for these videos..........!
It's amazing like a playing a game
Superb walter L. ❤
Those chalk skills tho.
Frequency of dots = arm speed x hand pressure
I hope Bob's pictures are in a museum
What a teacher even I found Issac Newton in his class at 11:02😁
Best Lectures ever !
It's a very hight and fruitful educational process
thank you very much professor Walter Lewin

11:02 newton spotted wearing specs
love physics after seeing this video

Lectures by Walter Lewin. They will make you ♥ Physics
Your videos make people fall in love with physics.
We need this kind of teacher. I couldn't imagine how this can be explained in less than hour whereas, our math class makes very slow progress that's why I always advance my studies. I don't know if that's normal, but if it is, then normal is wrong (referring to our math class).
11:02 haha newton is learning his own theories
copied comment
I'm eren (11thgrade) solved the example questıon! (we learn derivative in 12th grade in tr)
I am a student of grade 9 in India. You teach in such an easy language that even I get your point!!!
These Lectures are so fun to watch
Even Issac Newton learned physics from prof. Lewin! @ 11:01
11:02 Newton spotted 😂
Even Newton came after death to attend lecture of Sir Walter Lewin.🙏
he´s just the best! I use these lectures on a daily basis to inspire me for my lecture! thank you so much!
I think this man just low-key taught all of us on how to technically get out of any future "speeding" tickets. Hahaha! Love these lectures!
4:50 that would have been funnier if he was talking about instantaneous velocity.
42:55 test of an actual cammera men
i love the lecture . clearly explained. keep it up professor
I am watching this classical mechanics lectures again just love this teaching
Hello Professor ! First of all thanks a lot for your brilliant lessons !
I followed your reasoning at 17:02 concerning the uncertainty of measurement and the fact that the 0.3% relative error concerning the distance is negligible. However, in determining the uncertainty of the velocity, is the following calculation correct:
velocity as measured = 148.5 x 10^-2 / (5.8 x 10^-3) = 256 m/s
maximal erroneous value on velocity determination = 149 x 10^-2 / (5.7 x 10^-3) = 261 m/s
Thus true velocity = 256 +/- 5 m/s (and not +/- 4 m/s)
5 / 256 = 0.0195 so the relative error concerning the estimation of true velocity is still just below 2%, as we wanted.
Best regards,
JM
:)
Shall I take this for a yes ? :-)
I had the same doubt i suppose the smile face means yes
I have very high difficulty understanding physics in my university since the teacher doesn't give a damn. But you care.
Thanks, you are very respectable professor.
Hye sir,
The lecture was absolutely mindblowing. What made the lecture more interesting was the Experiment and their analysis. The concpets were crystal clear.
