I'm in a Indian boy, I'm in 11th grade and i used to watch your videos for practical experience as a suppliment for my neet preperation. Thank you❤ prophesor
These lectures are true treasure. It's almost like youtube was invented so they can be shared here. Thank you professor, for bringing your love for physics to many people out there.
one of the greatest physicists ever lived thank you prof lewin for helping us as students and God bless you. brian from south africa university of zululand
"PHYSICS WORKS AND I STILL ALIVE" The great speech and it gives me goosebumps everytime when I study physics. Thanks professor. Love and respect from India 🇮🇳🙏🇮🇳
Waoh am a student.... In college have didcated my whole time helping friends with problems in physics I have never understand Conservation Law The way I did today professor..... Thank you professor
You are the best physics teacher I have ever seen. I heard about one of your quotes which says that teachers who make physics boring are criminals.:) ever since then , I have been watching your lectures. I have visualised and learnt a lot of things Thank you so much :)
I'm a high school student from Sweden. At the start of the first Phisycs course, we learn about experiments and how uncertain an experiment can be. For example: It covers human aspects like observation and reaction time to name a few. It also covers technological factors like our equipment and our measurement tools. Very useful! Love your lectures!
teachers like you makes physics interesting i love physics but after watching you lecture i fall in love with physic i also want be like you sir thanks for inspiring
Sir well, I am from India but feeling love with your videos and obviously watching this video nearly after 5 years ..................................................
I am a high school 12 grade students preparing for NEET exam ....your lectures helped me a lot while i am preparing....real realistical conceptual funny .....love you sir
Fantastic show, Doctor! Great teachers are showmen, and you're outstanding! Slowing the footage to 0.25 made the final minute of the presentation THRILLING!
@@lecturesbywalterlewin.they9259 You're welcome, Doctor. I have a special love of pendulums as a musician (and a former physics teacher), and I have created metronomes of every variety from Winkel's ideas (Harrison used the double-weighted even before in one of his marine chronometers) to Weber's Rhenish inch pendulums for timing. I wonder, if it's no bother, do you know of a time when in the 18th or 19th centuries that scientists like Young or musicians like Beethoven might have used the OSCILLATION instead of the VIBRATION when determining metronome markings for their works ... super curious if you might know. Thanks again, and keep on doing what you do; you're amazing at capturing our attention!!!
@@lecturesbywalterlewin.they9259 Statement: By matching vibrations (beat rates) of two sets of physical and simple pendulums (+/- 0.1 beats) and measuring them (+/- .003 M), I find that the physical pendulum and the simple pendulum have a 1.5:1 ratio with respect to L; therefore, the formula for a physical pendulum as shewn in the video is: T= 2π ((2/3)*(L/g))^(1/2) NB: The mass (M) (because of its equal distribution in the phys. pend.) and the displacement angle (b) (too small to fall out of isochronism) are not necessary in this equation.
I am a 7th grade student , Your lecture makes me a passionate lover of physics Thank you sir for making a very complex subject like physics so easier for us 🙏🙏
Your lectures never cease to amaze me.....You have the capability to turn a difficult lesson into easiest chapter that can ever exist..... your lectures helped me to explore different topics ... Thank you to the power infinity ♾️ .....Lots of love 💕 from India.
Speechless..I dont have words !!!!!! Like how can a person be so good in physics....you are actual and true inspiration who aim for physics in future; Thanks a Lot sir for igniting the inspiration among us...sending you Lots of love; Hope your well sir;!
THE STUDENT THERE ARE ACTUALLY LUCKY......PHYSICS WORKS 100 PERCENT CORRECT SIR....I AM LOVING PHYSICS ONLY BECOZ OFYOU SIR...,,,TEACHERS LIKE YOU WAS VERY RARE NOWADYS SIR ..IN THIS GENERATION TEACHERS ARE JUST TEACHING FOR NAME SAKE...BUT YOU OPENED MY EYES IN THE WAY I SAW THE PHYSICS.....LONG LIVE WALTER LEWIN ....SIR
I am a jee aspirant from india , I would like to bow down to you professor 🤗 for your practical visualisation of concepts that help me a lot in a deeper understanding of physics ...❤️ Again thankyou sir ❤️
Professor I am from country called NEPAL and I am just at 9th stander though I understand your all videos. You really explain in very simple and realistic way. Heartly thanks professor
I think sir Walter Lewin is the toolsy to make physics more enjoyable to people.He has proved that 'Physics' is not a simple word . It's a dream , it's a reality.Thanks a lot for spreading the love of physics
This lecture was not just a regular one, it is more of an exhibition and the one who on stage to perform it was our great lecturer of all time. Thank you sir Lewin for having show me the beauty of physics again after so long… ❤❤ Hope you still doing well.
Brilliant lecture. I am an electronic/electrical engineer with a PhD in acoustics, that has loved physics - particularly astrophysics - for years. I am by no means an expert, but I have managed to (whether it be accidentally or not) find myself correct in many debates with those - including astrophysicists - that are smarter and/or more respected/educated than me. I remember proposing the anti-photon as a reason for the double slit experiment, getting laughed at in university for it, but then being asked to come back and explain how it might work. But, over the years, as I have followed physics - particularly astrophysics - I have an uncertainly about some aspects of conservation of energy. Namely the claim that energy can't be created or destroyed. As such, I have come to the conclusion that - if modern day astrophysics is to believed; A) Energy can be created or destroyed; and it doesn't only change from one form to another. B) Energy conservation only is local. Examples within the universe where energy is created/destroyed, are as follows . . . Evaporating black holes are one, and the decaying cosmic microwave background is another. Where is the heat energy from the latter (the decaying cosmic microwave background) going; if not being destroyed? Also, where is the information, heat, and other energy from the former going; if not being destroyed?
I am a history student , but nowadays I watched some of your videos and it made me intrested in physics, so in my 5th semester I opted Astronomy and astrophysics as my opencourse subject
There was so much more I wanted to tell you when I had the opportunity to meet you last July. I was very fortunate to take physics in high school... We did go over error! Many of the experiments you perform in 8.01 we did in high school lab :)
@@lecturesbywalterlewin.they9259 I hope you're safe during this time. My heart goes out to any directly affected by this pandemic... I've been in self-quarantine for about a month here on Long Island and am looking forward to a time when I can resume my trips to Cambridge... I'm sure we all are looking forward to a return to normalcy...
Well, this man was born in the Netherlands (yes, in Yurp, next to Germany) in 1936 and around 1965 he started working at MIT. So he grew up without inches and feet! I am Dutch too, I know the problem. The rest of the world is in love with inches, feet, stones, two tastes of miles, Fahrenheit and whatever. I can not get used to these strange numbers and I don't want to know what Fahrenheit was thinking. The only one scale more bizar is Delisle. The higher the number, the colder it is. Yes, an inverted scale. Great. Of course we understand and if needed we get used to your units soon enough, but a scientist must get tired of all those conversions before and after the actual calculations. Or he must use different constants for the oldfashioned units, which is just as annoying. Tradition is okay, but it has toooo many drawbacks. A funny example was a giant hot air balloon, a Frisian cow. Drawing was in centimeters, and it was produced in the UK, in inches. That's a whole lot of volume more than expected. So, the balloon pilot said no thanks, and in the end somebody else bought it and installed a very large basket. This is a true story and there have been more cases of confusion just like this one. Awkward. So, thumbs and forearms and feet and stones, funny, but no thank you. No hard feelings, people start argueing about such things, viewers of this video know better. It is the way it is. At least I hope you liked the giant flying cow!
At 10:47 I think the Reason why your Grandmother was right is hidden in Gravity When we are Vertical Sir our neck muscles stiffen hence shorter And when we are horizontal our muscles relax and no unnecessary strain on muscles so they can relax hence longer... It is like the spring under weight and spring lying horizontally
🥺💬 Very nice example as he told angular velocity concerns as external force. 🥺💬 He is correct Energy conservation, if no additional force applying then it cannot change direction or target height.
I'm an Indian kid and we starve for practicality thankyou sir...loads of respect to you🇮🇳
I feel you. Especially the ones aiming for JEE. Only formulas, no practicality
