I love this guy! I would enroll in whichever college he is teaching at just to attend his lectures. Physics is not my thing, but he makes it so interesting I want to learn everything this man has to teach!
whmozart I was 43 years at MIT; I retired in 2009. I gave 2 lectures at MIT and 16 lectures in Japan and India (2012 and 2014) after my retirement. My "farewell lecture" at MIT (May 16, 2011) has is my mot popular lecture. It has been viewed 4.5 million times. ruclips.net/video/sJG-rXBbmCc/видео.html
I am doing Electrical Engineering, and I came here accidentally, but ended up watching one lecture after an other without getting bored.. Walter Lewin is a great teacher, and i'll buy his book some day.
Prof. Lewis’s infectious enthusiasm inspired me almost 2 decades ago to study physics after I finished my basic medical degree. I have only joy and satisfaction for doing so, no regrets. I’ve gone on to make some fundamental discoveries of my own in the theory of wave interference. Thankyou so much sir! Wish I had the chance to meet you in real life.
@@lecturesbywalterlewin.they9259 Thankyou sir for your reply. It’s such an honor! In case you are interested, the name of my paper is “multiple slit interference: a hyperbola based analysis” which can easily be found and downloaded on a google search. I was very blessed to have had such a great teacher as you. You are a rare gemstone.
Astonishing didactic quality, at the very highest level, very possibly unique! And this is no vulgarization: the reasoning is as rigorous as it needs to be, and the equations are introduced as the obvious language of Physics, not as a hindrance to be suffered. I think all Professor Lewin's students get to feel the esthetic emotion of practicing Physics and the joy of understanding the physical world. Superb teacher, in the highest sense of the word!
This is the way how physics (or any subject like that) should be taught... Love from India sir... Hope so every schools or institutes professor (or sir) starts explaining the things this way..
Professor I want to thank you for wonderful work and your upbeat spirit. I am lying here in a Covid-19 ward feeling rather down. Your infectious love of physics is the only disease I want to have and maintain. Thank you for your words helping me now.
19:20 - you cannot hear these organ pipes with such a low frequency, but you can feel it with your body. If you have ever visited the real organ concert (not listen by TV or headphobes) then you will feel your body vibration at low sounds frequencies. This brings you to the fantastic feeling of the live organ music.
Great sir, This is your love with physics that makes you different from many others . I loved the way you teach and really i do wish if every institution give practicals more importance than the theory.. Salute you sir.. May you live long and healthy life and keep teaching us this way.. Thank you With regards, Piyush Awasthi, INDIA
I could feel your passion to make others knowledgeable, sharing your life experiences in the subject that you love so much. Hats off to such Guru's. You made the session so interesting with those live demonstrations.
You are just amazing sir. I am a PhD student in Physics and the way you teach is giving me a bright view of the nature to love science and our elegant world. I remember once you said "You must love it or do not touch it"
Still remember why army is not allowed to March on pull so that resonance of army men March doesn't match with natural frequency of pull because if it does then pull will resonate up and down.. Love physics😍😍😍😍😍
Watched this in 2016, 2017 and now 2018. Each time i watch it, I learn something new and enjoy the beauty of physics. Thank you sir :) I think I have an emotional resonance for you haha.
As a an amateur violinist I found this really interesting. A violin teacher I had a few years didn't understand why I tuned to 440hz on the basis that orchestral stringed instruments resonate better at 442hz. I still tune my violin to 440hz to this day.
THIS IS PERFECT!!!!!!!!! I am trying to describe harmonics and timbre to a friend who is helping me make the tools I need to make trumpets from scratch, and I showed him this lecture and he got it!! what an awesome lecture and what an awesome professor!!!! - a trumpet player
THANK YOU SO MUCH Dr. LEWIN! I was wondering if you have an email address or some other means of contacting you. I have some questions on harmonics, progression, timbre, and so on for a project I am working on that I cannot seem to find definitive answers for, and it would be an extreme honour to have your take/opinion on it! thank you so much again!!! Ezra
I was reading the 1st chapter of "For the love of physics" and Walter said about how physics explains why and how many things are and do....and "why a flute makes sound" was on there......I'm gonna watch every bit of everything Professor Lewin.
You are one of the most indispensable gem for the whole world. I admire you the most sir, your lecture and practical experiments simultaneously let us understand even the most toughest topic in an esy way. Hats off to you sir.
What a great lecture and demonstration sit may Gid give u a long life u are the ver very great teacher of physics i learn many thing from u i salute u sir may God give along long life
Maybe passion can’t be taught, but you can certainly teach with passion, thank you for sharing top quality content for free to everyone, you never know who can get inspired.
was reading the wonders of resonance chap harmonies of strings and winds in YOUR BOOK SIR AND GUESS WHAT RUclips RECOMMENDED ME THIS GEM LECTURE I DIDNT HAVE A BETTER FEEL OF HARMONICS AND RESONANCE EVER !!!!!!!!!
Hello professor!😊❤️ Now a days I'm reading your book 'for the love of physics'... It's very motivation and also informative. It gives & develop different approach of thinking... ❤️❤️
The last moment when he changes his voice was really amazing.You are the GOD of physics.I am in love with physics.May you live long,so that I can get an opportunity to meet you.🙏🙏🙏🙏🙏💕💕💝💝.LOTS OF LOVE FROM ONAM.
I define 3 phenomena regarding self-excited vibrations: Natural Frequency, Critical Speed and Resonance. They are related but different. Natural Frequency is a physical property of any physical object dependent solely on the mass and rigidity of the object. Critical Speed is the turning speed of any rotating object that matches its natural frequency. Resonance is the extremely high amplitude response of an object that is being excited at its natural frequency or for a rotating shaft, at its criitical speed.
Violin 🎻 sounds more natural but look at the random frequency of electrical guitar ! 😳 Imagine what it will do to your brain,,even his voice frequency is not random like it..♡
All I can say is you are the best professor that i had ever seen. I loved all your lectures and the most remarkable one will be your last lectures with pendulum experiment along with the scattering of lights , that was really awesome. You made me to be more in love in Physics as I have always been. Thank you !!!!!!
I'm studying the relation that exists among physics/math and music, for instance: a major chord which is audibly consonant is composed by the first three odd harmonics, thats: 1, 3 and 5. If 1 is C, then 3 would be G and five would be E, so you would have a C major chord (C+E+G). On the other hand if the frecuencies are obtained by dividing the fundamental frequency in integer numbers (instead of multiplying it, as in the example above), that's: 1/1, 1/3, 1/5. In this case if 1/1 is G, 1/3 would be C and 1/5 would be E flat, that's a C minor chord (C+Eb+G) which is also consonant. The interesting thing is that while mathematically this chords are inverse (the Major and the Minor), musically each one of them evoques a certain mood or feeling which, although music is subjective, could be generalized as oposite. In the one hand, a Major chord evokes a harm, happy, light sound, while a Minor chord evoques a cold, sad, dark sound.
I was actually able to see a colour that humans aren't supposed to be able to see some time ago - it is sometimes called "yellowish blue", and it is a weird mix of yellow and blue that is very different from green - basically a yellow/blue mess where both colours are visible at the same time. You can see that colour by having blue and yellow next to each other and then have them converge with your eyes, kinda like when you look at "Magic Eye" pictures. There are several images like that on the Internet if you search for "yellowish blue".
The instrument, in 12:02 minutes, is built on same principle of EK-TARA (Ek means one and TARA means string). This is used in Bengali folk songs in India and Bangladesh. Many songs by Lalon Fakir has only this instrument. Many such folk songs had inspired Indian freedom fighters.
Sir you are amazing.........full concept..... Your lecture is like a Hollywood movie....... It gives the same pleasure to me when I watch a Hollywood movie......... Love from India..... Genius
Thank You professor. One can tell just how much you care, an example: your use of Emma's instrument. It must be precious to you, yet you use up a few plucks for all of us. Very generous. I'm watching carefully all of your lectures, only pausing, to research something I didn't understand. Thank you.
please professor walter lewin, i have already attended your lectures from 8.01 and 8.02, i think the best classes i have ever seen in my life. I am Brazilian and do not understand English perfectly, and the 8.03 classes are not translated. I ask that if possible, you provide translations for 8.03. Thank you.
You are a great professor, I wish I took physics at that college! Osu could learn a thing or two from this video about teaching physics to inspire students to maybe do a minor in it instead of teaching it to weed students out. For a while I lost my interest in physics due to how my college teaches it but this makes me interested in it again, thank you.
Dr. Lewin , Thank youuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuYou are amazing You Wouldn't believe How much your lectures affected my passion to science Students at MIT are so lucky to have you there. I was always hoping having brilliant teacher at this unbelievable level of knowledge. MIT thank you for sharing this video , keep on
Dear Prof. Lewin, yesterday Thursday Apr. 28, 2022 I watched one of your interesting fun videos in which you asked to let you know about any advertisement being displyed in the middle of any of your lectures. So, I´d like to kindly let you know that at this particular video about "Resonance and the Sounds of Music" up until the minute 56 I have seen at least 4 adds. More importantly, I wish you're doing good and also want to express my gratitude for all you shared knowledge.
I just clcked here randomly and ended up watching the whole thing. Fascinating! looking for more now!
There is plenty "more"
I love this guy! I would enroll in whichever college he is teaching at just to attend his lectures. Physics is not my thing, but he makes it so interesting I want to learn everything this man has to teach!

wait a second... are you THE Walter Lewin responding here??
Yes I am the REAL Walter Lewin and I run this channel. The woman who is playing the violin (see thumb nail) is my daughter Pauline.
I am doing Electrical Engineering, and I came here accidentally, but ended up watching one lecture after an other without getting bored.. Walter Lewin is a great teacher, and i'll buy his book some day.
Did u become an engineer now?
It seems that Walter Lewin is like the official unofficial mascot for the Dept. of Physics at MIT. Love this guy.

The great thing about reading your book would be hearing the lines narrated by you inside .
A great legend !
Sir Walter! I am a musician, and thank you for that wonderful lecture! You made me love music and physics even more! 😁
when your passion is your profession...
That kind of dedication shows up...
I had also gave 10 minutes standing ovation in my room after seeing this lecture
:)

Gets you to the start of the wine glass break attempted
BUT WATCH THE ENTIRE VIDEO...TRULY AMAZINGLY EDUCATIONAL AND ENTERTAINING!
It is a amazing lecture wish I can hear it 40 years ago , thank you Prof Lewin

Great lecture. Thanks to your lectures I fell in love with Physics. Greetings from Russia
was reading the wonders of resonance chap harmonies of strings and winds in YOUR BOOK SIR
AND GUESS WHAT RUclips RECOMMENDED ME THIS GEM LECTURE
I DIDNT HAVE A BETTER FEEL OF HARMONICS AND RESONANCE EVER !!!!!!!!!
Wonderful!
Sir today is 5th Sep, a special day for appreciation of Teachers and for me you are the worlds🌎 best Teacher.
With 💘
Happy Teachers Day.
Dear,
You are the best of the best proffessor i ever seen...👍
Hello professor!😊❤️
Now a days I'm reading your book 'for the love of physics'...
It's very motivation and also informative. It gives & develop different approach of thinking...
❤️❤️
The best professor for sure. Mr Walter, we need people like you, here in Italy. Unfortunly I haven't seen any of them here yet...
+Marco Keep looking!
I can watch your lessons for many hours, very detailed, these explanations are wonderful,thank you very much for content you provide,professor.
A lecture which will be heard for ages ! Love for Physics and Love for Walter Lewin !
I love the way you teach
You are my first and adorable Physic Teacher and forever will be🥰🥰🥰
Sir, you may not aware how your videos helping millions of student, really you are God of physics.
I have only watched some of his lectures so far. Now I am gonna watch them all...
Divine knowledge god bless sir
I watched complete. ❤
What a lecture! Seeing videos of respected walter lewin sir i have made interest in physics so much.
This is very very helpful.
What a fantastic teacher!!!!!!
Best explanation ever seen. Inspired me to see all the videos . Thanks for educating us !!!
If all our mentors were as good we would be in a far better place than we are now - well done
The last moment when he changes his voice was really amazing.You are the GOD of physics.I am in love with physics.May you live long,so that I can get an opportunity to meet you.🙏🙏🙏🙏🙏💕💕💝💝.LOTS OF LOVE FROM ONAM.
definitely noble prize should be given to you for your way of teaching
23:00 It's amazing that I can feel the frequency difference just by turning the pipe!
7:22 Watch the guy with glasses and a blue shirt😂 Im right there with you
music...pure sensation. nothing quite like it. love

How is it possible for a professor to teach in this incredible way...I do not have the answer...It is just unbelievable!!!!!!!!!!!!
:)
Super sir , Explain is really good 😊
That little stunt at the end was pure commitment. Great guy and awsome lecture
Violin 🎻 sounds more natural but look at the random frequency of electrical guitar ! 😳 Imagine what it will do to your brain,,even his voice frequency is not random like it..♡
Absolutely Amazing!!!
This is the best ever physics lecture I have ever seen. Thank you soo much respected sir for enriching our minds.♥️ from India
this talk was for kids + their parents
Could not help stop myself watching the whole lecture ! Great as always.
you always have something new to surprise us. thank you, sir, for your great service
Everyone clapping.... 1000 years later still clapping ;)

how satisfying are these lectures..
Wooow, you are a great physicist.. Thanks for this exciting lecture 👍
It's my pleasure
Actually you can "hear" lower frequencies than 20Hz, but you recive them by vibrations of your body. So i think we can say, that we can feel them!
YES
Wow didn't know this, if I may ask are u doing something In physics
I was actually able to see a colour that humans aren't supposed to be able to see some time ago - it is sometimes called "yellowish blue", and it is a weird mix of yellow and blue that is very different from green - basically a yellow/blue mess where both colours are visible at the same time.

i wonder what is the frequency of walter's head
physics needs more bassoon solos
Exact explanation I was looking for. Amazing.
Great to hear!
