Physics isn't as difficult as it seems when there is a professor like Walter Lewin teaching it
✨ & way more interesting!✨
☺️
very well said
Absolutely correct✅ 👍
especially with a banana on his chest.
I bet aapne pura lecture nhi dekha🙂
Students who are attending live classes are so lucky ....
NO,There are worthy
You can say that gain
Yeah
Not anymore.
Not lucky but are worthy to it
Two years ago I hated physics but now I love physics because of your explanation and visualisation Thank you very much sir
You are most welcome
I like this blackboard
Better than smart board
Love from india 🇮🇳
yes
Yeah sure 🤗
46:20 well that's one way to make a point.
he came in like a wrecking ball lol
I can't understand how possibly and beautiful your classes are. I am preparing my physics exam watching you videos. Thank you for making physics spectacular (PS I even bought your book, loooking forward to having time for reading it)
You're very welcome!
Literally am not having words.. the whole lecture was just awesome...was in an awe the whole time how could anyone explain a concept so deeply with so much patience..hats off to the legend out there 🙂❤️
Thank you so much 😀
Love you sir u are the best teacher i met in my life 💕
@@lecturesbywalterlewin.they9259 if I want to study that college .what I do for study in that college.
How lucky those students who attended Prof.Walter's lectures?? One of the rarest eminent professor in this era. Respect& love from Nepal🇳🇵🇳🇵
finally a physics learner from Nepal, u r lucky too to have get to watch these lectures free on youtube
First time ever in my life I found phy6 interesting sir u r simply amazing 😊😊
😉😌
@@lecturesbywalterlewin.they9259 🙂
love the way you wrote Physics
You explained it so well sir, that the only thing that confuses me is that banana thing on your chest..
+Usamah Jundi If that's the only thing that confuses you, you did VERY WELL!
now i found some other thing that confuses me
i noticed that you used the -kx=-mg*sin(tetha)
on the pendulum system, but i suppose the rope is considered not stretchable? or is the K here is just a constant so that the Restoring force is directly proportional to the displacement? if so, why is the displacement considered x (the small arc formed), or is it because of the small angle you can consider it a straight line? thanks
+Usamah Jundi How many minutes into the lecture?
+Lectures by Walter Lewin. They will make you ♥ Physics. i am terribly sorry sir, i think i mixed up with an other video, so i think it is the banana that confuses me the most ^^
I may have found a hint in his book "For the Love of Physics". There he writes: ".. - and when after ten oscillations I turn of the timer, it reads 45.61 seconds. That's a period of 4.56 ± 0.01 seconds. 'Physics works!' I scream, and the students go BANANAS"
46:23 that was a real Miley Cyrus moment for the professor lol. He has such a passion for teaching , I wish I had a teacher like him in school than I wouldn’t have sucked in physics like I did back then.
You never look like an old man! Your love for physics make you look like a young person! You're always energetic!
He does look like Santa Clause tho
9:30 , Hats off sir, This is the best way to solve a differential equation my eyes have ever witnessed , Really you make us see through the equations, so visual , so natural.
Samarth Sai enterprises
actually so basic equation lol
Lol no, this way how will you actually solve equations involving damping or complex DE involving exponential and trigonometric something like AC circuit before steady state
10:00 mind blowing sine curve
Yes
That was very satisfying
That's how you convert a digital signal into an analogue signal.
It is teachers, and demonstrations like this that made me love science. It has always been my favorite subject. Teachers any less eccentric, and demonstrations any less dazzling risk being perceived as boring to the average student. This man is a genius and these videos are solid gold!
Your lectures are a gift to physics majors and in long term gift to humanity.
Thank you so much for your lectures. You cover the content in depth and very clearly. I also enjoy your experiments a lot; they really demonstrate the real-world applications of the concepts in a very amusing fashion.
Thank you Bowen for your kind words.
best part of this video was 0:18 -- that chalk technique was beautiful.
+christiantabile Look at this short video. czcams.com/video/raurl4s0pjU/video.html
holy shit he's a mastermind.
+christiantabile "He" = the person who answered your question! (Yes, Dr. Lewin maintains this channel and responds to comments. :)
this is really walter lewin? don't lie to me!
+christiantabile He is :)
I was swallowing the 50 minutes like a hungry beggar. Loads of respect from a far continent for you sir..🙇🙇
I like the way sir teaches each and every thing practically, he explained how the things actually works in real world. I had enjoyed this lecture very much. (JEE Aspirant)👨🔬👨🎓 from India 🇮🇳♥️
Yeah, unlike teachers in India. They are like: this formula does this so learn it all.
Hey will you please tell did you Crack jee?
What us your age?
@@aakashsrivastava133 ikr it made me think that SHM is boring man
@@aakashsrivastava133 , so India teachers do the same thing? He literally just talked and wrote on the board for 40 minutes........
Wow, excellent. I missed physics in university because I thought the math would be too hard. I'm now learning what I missed back then. Thank you for these detailed videos. I can only learn so much from the short 5 minute CZcams mass consumption videos with fancy computer graphics and no math. You are helping me learn about wave/particle duality, wave functions, electromagnetism and more! My favorite is the Heisenberg Uncertainty Principle video. First time I truly understood what it meant and what quantum physicists mean by "information" and "observation."
+Mod MINI I am glad my lectures work for you.
Me too. I missed physics at university until I recognized that when I wrote my flight simulator program.
Hats off to you sir. Love physics
5 minutes? Lol it’s a 45 minute video
@@lecturesbywalterlewin.they9259 Sir, how I wish I could attend your live classes ! 😊
This lecture is $150,000 worth in 2019, thanks to the banana :)
Thank You, Dr Lewin. I really appreciate how you compared the two formula; the formula for the pendulum and the formula for the spring and how you explained that mass has nothing to do with the period of an oscillating pendulum!
You truly are the best teacher. No debate. Non-negotiable.
Best teacher🥺 , not seen anyone teaching like this before , i wish if i could study from him
I never believed in LUCK until I came across Sir Lewin's lecture. His students are the luckiest when it comes to physics.... well we all have the same through this platform ❤
I love physics ive had a passion for it since childhood but i can assure you it is very difficult to explain these complex topics in such an engaging, thorough and precise way. Demonstration is everything! He does it so effortlessly you can tell he understands in front back and sideways and really deeply cares about making it click for his students. Thats a passion for physics, not everyone has it but those of us who do really wamt others to get the same understanding and bewilderment the universe brings to us
what a great teacher you are, Sir! Time period of pendulum is independent of mass, now I won't ever forget this. But the sinusoidal wave with that paper, that was my biggest confusion when I was in high school. It couldn't be explained better. You're truly great sir!
Wow, thank you
I had a teacher like you in my tuition classes! He is also a great teacher! I hope I meet him again after getting my medical college.
Btw great explanation sir:) you really make physics easy! Thank you so much 😊
How I wish I'd come across this earlier... Best explaination!
+Preethi N :)
Thank you very much, it is hinting me towards the comprehension of universe and matter. I am a civil engineer aged 60 , the subject civil engg primarily based on hooks law, now realise what oscillations are from spring theory into string theory of quantum mechanics.
R u mallu??
The Best Physics teachet I've ever seen!!!Hats off to you sir! Greetings from India
Amazing professor! Imagine how much time he had to spent to give his students such an exciting lecture.
Awesome. The last experiment really refreshened the mood, I wish we had schools like these.
its MIT not school
i used to not be interested in this kind of stuff but the more i watch your lectures the more i become fascinated with everything that you talk about and it makes me want to learn more
Thank you so much sir. For the first time i could involve myself in physics for 47mins straight, and not force myself....this is a great achievement for me..😊😊
This man is like Master and so accurate in physics calculation😱😱
Professor hanging from pendulum, this is what MIT is and teachers like you make it what it
is.
This is my favorite lecture.Very VERY VERY exciting.
I can't express how happy I am to watch this lecture.
I am going to get in high school(I am going to get my result on 24th march), I am extremely privileged to see these lectures from my home(though getting into MIT is my wish and dream,it is difficult).
Bro you are now in 11th so what do you say....
Aren't you fucked up if took pcm...
46:51 that girl in the right lol
ahahahahahahaha
Keen observer
She is a grandma now
How do people get into MIT and then sleep while others just dream for it
One of the greatest Physics teachers the world has witnessed. Thank you very much Professor Lewin for your teaching methods that has literally set a standard of teaching Physics. I'm blessed to find these golden lectures during my lifetime. Stay well professor!
You're very welcome!
What an extraordinary teacher! I would not miss any day class if I had this teacher!
*imagine walking past his class and seeing him swinging in the class*
@scftlcve i thought the same thing LMAO 🤣🤣🤣
Mr. Lewin, you are a great teacher. I enjoyed learning from your video.
:)
Every time I watch your lectures,I am inspired to become a better teacher. You make things look very simple, being a teacher I know a lot of effort goes into making it so easy to understand. Great respect Sir.
This is the killer way of Prof. WL to deliver concepts to students. Very helpful session.
Happy teachers day sir. Love and respect from India. 🙏🙏🙏 You are the greatest teacher of all time.
:)
hey I'm an 11th grader Indian student is this lecture relatable to our course.
@@shambhavimishra4503 yea for the practical and fun purpose go for it ..
But not boards tho...
But it's of course awesome ..to take these lectures
@@shambhavimishra4503 this shows that you have no knowledge
at all

Thank you for this, you're the best teacher I've ever seen
+Joao Victor Thank you Joao
This is called teaching REAL PRACTICAL PHYSICS...Hats off to you sir...👍👏👏👏👏👏🙏🙏
This level of teaching motivates some beautiful minds so much, they reach the level of complexity and appreciation of nobel prize. You are beautiful Sir.
39:25 the spring on Professor’s left is nodding along with his statements
It’s really honor to seat in his class!
Speechless! Absolutely spectacular! Definitely the best physics class - and possibly the best class - I have ever seen in my life! Thank you, professor!
Physics works!
LOVELY lectures from Prof. Walter Lewin. Really hope that I have lecturers and concept explanations that are as great as Prof. Walter here in Indonesia. Thank you Prof. Walter !!
Once I got the solution of angular frequency equal to square root of the stretching coefficient divided by the mass of an object on a spring by using calculus in our opposite force formula, I felt so much euphoria, I almost passed out. Thanks, professor Lewin, your lectures are a godsend.
Yes really beautiful to who seeks. I have no words express . Once again thanks . The time period for planet Earth works out to 8.911 sec. For 1 day of acceleration. I don't undrstand what string is holding us.
...the best lesson is in the last few minutes. Practical explanation is the key to understanding a physical phenomena. He is the best teacher ever!
What a wonderful, wonderful teacher. Thorough, yet not wasteful.
WHAT A GREAT LECTURER.
AN DXCELLENT DEMOSTRATION
BY HIMSELF. HIS STUDENT NOT
ONLY LEARNT A LOT BUT ALSO
ENJOYED.😁😁😁👌👍👌👍🌷⚘🍁
I AM WATCHING TIS LECTUR AFTER
5 YEARS.THE TEACHER HAD FULL
COMMAND OVER HIS SUBJECT IN
PHYSICS. WE NEED SUCH A TALENTED
TEACHER.🇵🇰🇵🇰🇵🇰
sir that why we love you you dont give lectures of physics you also apply in class
a huge respect for you from whole india (and also sir please collabe with physics walla
i find it stunning how you do the physics in an empirical way to then do the maths. your classes are espetacular, i wish more physics teachers realized how actually showing the application in real life of the subjetic helps the students
Omg! I am revisiting my physics from highschool and mechanical semesters and now I m loving it. This WL is agreat teacher. Wish we had teachers like him
Your lectures are very useful for me thank you ❤️
Wonderful
Professor.. Thank you for the amazing lecture... Initially I hate this topic but after seeing your lecture, I am in love of Physics indeed!!Thanks a lot.
yeah he do keep you from going to sleep
hope for the degenerates?
I had a hard time learning those! I wish I had a teacher like you. May Allah bless you and you remain in sound health to teach millions! Amin! ❤️
Amazing teacher ever I have seen and known....... He is really a legend and we indians also need this type of teachers.... Respect for u sir... From the bottom of my heart ❤️
44:05 - Professor Lewin fiercely attacking the start button, complete with a karate shout. :)
47:00 what we all came for
Themks
Thx
Lol
No teacher can ever demonstrates it better than you .. your the best physics teacher I have ever seen sir .. lots of love and respect to you sir..
Great pendulums experience!!! Thank you so much, professor!!! I will never forget that T will just relate to the length!
this is what we called PRACTICAL KNOWLEDGE...👌👌👌 Superbb
Thank you for turning all those crazy looking equations to something I can actually understand, and then go on to explain to other people.
That's great!
He makes learning fun, and that's when you absorb the most information.
Perfect example for the quote "No pain ,No Gain". You must have taken such an amount of effort and pain to teach them.They are lucky to learn Physics from blessed hands.Enjoyed the lecture Sir...!
Awesome
now I realize that
physics works
Physics works
Physics works!!!
Physics works....and you still alive😊
"Thank u sir for making the lecture so good"
THERE IS SOME SPECIAL FEELIN YOUR LECTURES THAT MAKES PHYSICS LOOK MORE BEAUTIFUL. 😊😇😊
"You made my day, because i was struggling to understand these topics"
LOVE FROM INDIA🇮🇳
Tonnes and tonnes of love from India...
It is really unbelievable.... Because how could someone explain each and every concept with demonstration...
Hats off to Walter Lewin sir...
You will live forever..
We love you forever...
Sir after this watching video I have realised what physics in reality is . You are awesome professor . I would like to meet you at least once in my life . I touch your feet sir with huge respect . Touching feet of teachers is a culture in india . We all Indians are proud of you. Hats off to you sir🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
All the best
Great teacher. The best way to teach physics.

Very interesting.
Though I cannot be present at your lectures physically but still I can enjoy physics through you tube.
Respect and love Walter Lewin Sir.
Long live sir.... Knowing something better than other is nothing..but giving that learning to someone else in a better way is the best . And you are best.
Ill always think of this guy as Professor Bananapocket
From Kenya, I must confess Prof Walter Lewin made me believe physics indeed works! big up prof.
I am so lucky to find this series. Teaching is art and I think he is the grandmaster.
I appreciate students have a professor like you 🎉
I am a medical student from India... Left physics years ago ... But your lectures sir are again helping me to understand one of my favourite subjects deeply again ... A lot of respect sir.

Thank you for sharing these wonderful lectures. It doesn't take to be a genius to understand your lectures because you present things in a clear and practical way. If all teachers were like you - we would have a new Albert Einsteins every decade.
Glad you like them!
When Will we have A teacher Like U In Nepal🇳🇵🇳🇵
Without a doubt Prof WL is one of the most effective educators around, even if some of his breakfast is stuck to his shirt.
CZcams recommend this auspicious lacture after 6 years ✨💕
So good! The presentation as well as the physics. What a joy!
Students over there laughing at him and here me be like why we don't have teachers like him 🙃
They aren't kidding at him - they are just laughing !
