I’m an amateur radio operator and have been making HF and 6M band (50MHz) contacts across Europe tonight by bouncing the signal off the aurora, the sound of the received audio is very distinctive. Great fun.
I'm pretty sure I 'heard' the X-class flare that occurred just after midnight, without any radio equipment. I also had a phone charger blow on me just before midnight.
Hi Prof. Lewin, I’m a big fan of you and your lectures and still watch some of them. You opened my eyes for the beauty of physics when I saw you on ‘de wereld draait door’ many years ago.. I started watching your lectures on MIT-Open coureseware and read your book 'For the love of Physics'. Now i'm really a physics enthousiast and know, and to some degree understand how, Physics Works! Thanks for that! Last friday I was very hyped by the news of the high chance of seeing the Aurora Borealis in my home town Barneveld in the Netherlands and I made it my evening mission to see it.. and I did! It was Spectacular!
Saw it in Dundee, Scotland (56 degrees N) at midnight. Large thick stratified bands of eerie light in yellow, purple and green colours stretching east to west. Super intense, and I hope everyone else catches a glimpse too! Good to see you Prof... hope you and yours are keeping well!
I was fortunate enough to see the northern lights for the first time in Southern Canada between 11pm and midnight. A kind stranger explained the basics of geomagnetism and coronal masses to the rest of us out on the small trail by my house under the cover of near-total darkness. It was hard to see the actual northern lights, they looked more like tinted clouds, but under the lens of my phone camera they were beautiful and bright. I had never seen such vibrant purples and greens. I think it was the most stunning thing I have ever seen in my life. Thank you professor for your brilliant videos. I am majoring in biochem this fall, but I love learning just how beautiful physics can be.
I read your book called For the Love of Physics. In this way, I realized how entertaining many of the things I encounter in daily life are. Your book added color to my life. I love you Walter Lewin
Well i will try again tomorrow, just tried to see something in Groningen but it's completely clouded right now. But tomorrow night the predictions says that it will be a complete clear sky, so i am really happy you said i have a chance tomorrow!!!
Hello Sir, I just wanted to thank you for all the effort of your each lectures and youtube videos. I study electrical and electronics engineering but After I watch your videos, You make me love physics and Now I decided to learn more about physics. I really appreciate for everything sir. Lastly, I really loved your book! . Love From Turkey
Been watchin solar weather for a long time now! Solar propogation states the effects tonight from the CME on the 8th as extreem! Thanks for your post Doc!
The skies above Wiltshire, England lit up once it became dark, and continued to grow in intensity as the moon set to the Northwest. The initial glow was a light green that spread quickly to span the entire northern horizon. As the lights grew in intensity the colours became more vivid and reds blues and purples could be seen to the West and East, with the North still having a bright green hue. At times the intensity would increase for a few minutes at a time and high contrast banding intensified, with the bands all converging overhead and slightly to the South. At times green colours could be seen to the South, but these were more patchy. It was awesome.
I live in 44805 Bochum, Germany 51,8° and in the night from Friday 10.5.2024 after Saturday 11.5.2024 i stood with my twin brother in a nearby field from 10 p.m. to 1.20 a.m and took very impressive pictures of magenta and green polar lights. I got much more than I expected and i have never seen green polar lights before. Perhaps the first and last time to experience something like that. The special was, that the polar lights ranged from north - west over north to north - east and from the horizon up to an angle about 40°.
I live in northern Switzerland. It was the first time I saw northern lights. It was spectacular to walk out of the house and to see this phenomenon happening. I didn’t have words for it. Hope you all got to see them as well!!
Hello sir. I 'm your regular student from India.. I just passes my 10th grade. I follow you since class 8th when I knew nothing about physics😅 and learned many things from you... Sir I was waiting for your recent video from a long time..sir keep uploading your videos, students such as me love studying clear and crystal concepts of physics from you.... ❤❤
I am in East Tennessee, USA. I went out to check the sky at 10:10pm local time. The northern sky was pinkish red in a way that did not look normal. But the light pollution where I live is so strong that it's hard to say what I was really seeing. Maybe I will be inspired to drive somewhere darker before dawn, but I have been sick, so maybe I won't be up for it. Light pollution certainly cuts us off from a lot of beauty.

sir i 'm studying in class 10. i and my friend have a doubt that In the case where the angle of incidence is zero(Normal Incidence) , in that case when the light came from denser to rarer, i think it would bend away from the normal because if it will not bend then it will take less time to cover that distance. But we know that time is always Constant when source is same.. but in reality it passes without deviation . So where the problem is as both statements are about same topic ?

Do all the homework and take all my exams. *I guarantee you that you will then do very well on the Physics portion of any freshman college or JEE exam* You will find all information you need on this channel in three playlists "Homework, Exam, SolutionsY & Lecture Notes".
8.01 & 8.02 will each take about 200 hours, 8.03 about 250 hours.
Hello professor im from INDIA i just really wanted talk you in conference but dont have a specific topic to talk just about life and physics relation and many more with you professor i would be more & more happy if you accept my request... ❤
you can only send me msgs here
why do we only have northern lights - and nothing near south poles?
There is also the Southern lights just the same
*I am sorry; ofcoz Southern light as well* *More generally it is called Corona Borealis*
that’s not true. The Corona Borealis is a constellation. The Northern Lights are called the Aurora Borealis, while the Southern Lights are called the Aurora Australis.
I'm having trouble with my mobile sim network connection (it's non existent - I'm using Wi-Fi).
Could this storm be to blame?
could be right

I had a go at part (a) of your latest problem.
Am I at least getting close to the answer or way off? I had to make further assumptions to get my head around it, but I think I may be still off a bit...
Am I right with this assumption for the y component of v₀, for instance? 😕
v₀ᵧ=√(2gh), where h= change in height over duration of rocket burn.
Sorry that I haven't had time to do all parts as I had connectivity issues. 🤷📴〰️☀️🌌
@@lecturesbywalterlewin.they9259 I didn't read the problem correctly and used the wrong angle! 🤦. I will leave my alternate version of the problem there anyway.
You mentioned WW2 and I was thinking of Nazi rockets!
Professor Lewin,
I'm a student in Kerala, india. I have completed my 10 th grade. I love to study physics. My wish is to become a physics professor at MIT like you. my family background is below average.what preparations should I take now to become a physics professor
high school, then bachelor's degree at a college, then PhD in Physics at the best graduate school that will accept you depending on your academic course records
@@lecturesbywalterlewin.they9259God help me, the man says, I have no chance. What do you say, may God help our friend
Sir i also want to see that sir tell me how to become master in physics and prepare for jee advance physics sir I'm jee aspirant sir please help me
PhD in Physics is a higher degree than Masters.
@@lecturesbywalterlewin.they9259but sir I am a jee aspirant and I want to learn properly physics that will come in jee exams sir,I was not talking about degree sir,I was talking about to get indulge in physics completely
Sir i am in class 9 can you please suggest me a good physics book written by you
I would be very grateful if tou answer me 🙏😊
For the ♥️ of Physics
sir why dont you come to india to meet alakh pandey physics wallah and the students of physics wallah and also you could know about the education system
I have been 4 times in India. My last visit in 2014 lasted 6 weeks and I gave 8 lectures. Given my age and the air polution in India my medical staff does not want me to go back to India.
Sir I studies in class 11 how can I know physics very well
eat yogurt every day but *never on Fridays* - that also worked well for Einstein and for me.
@@lecturesbywalterlewin.they9259What is the secret? Why not Friday?? I will be glad if you answer
@Walter Lewin Sir, I want to discuss you something personally please!
you can write me anything - I will then read it but I will not post it. Thus no one else will see it. However, I will then not able to respond to you.
just love you sir .I wish if i could get a heart from you.❤
I only send hearts to women
@@lecturesbywalterlewin.they9259 😂
@@lecturesbywalterlewin.they9259 I'm not women but as a student it will motivate me
Good Eve sir
Sir is jee advanced level calculus enough to understand 8.03 lectures and it's numerical problem
Thanks
probably; but ask your marth teachers
@@lecturesbywalterlewin.they9259
Sir I don't know any such teacher personally ........
So I request you if you can suggest me from where I can learn calculus for your 8.03 lectures ...

@@lecturesbywalterlewin.they9259
Sir are you talking about
18.03 Mit ocw Differential equations by Prof. Arthur Mattuck ?
At last thanks for your reply sir
Sir, I am a physics lover. And I believe I have created a hypothesis on how electrons behave when they arbitrarily move among their clouds within their respectice shells. I am 15 and dont have any idea how to express my thesis in general public. Please help me in this regard, I would be glad.
Respect from a physics lover from India❤❤
*first take courses in advanced QM*
Thanks sir
😇😎😇
हिंदी india😂😂
you are nothing compared to einstein your physics is nowhere near einstein or me
no one is like Einstein - he was a super giant
Have some respect for Prof Lewin - he is also a super giant. Thanks Prof for your wonderful videos.
lol, look at you.
@@lecturesbywalterlewin.they9259Don't mind some talkers. You are great 🤝
