this is the first physics lecture that I never got bored of throughout the entire duration of it

Ok, now let's solve jee advanced pyqs

I think at the end of this lesson I would have spontaneously clapped my hands such was the beauty of this masterpiece of teaching. So far the best physics teacher born on this blue dot.

I once saw a triple rainbow. I was driving 1 car and my brother driving another. We both pulled over on the highway and got out to enjoy the sight. This was pre cell phones, so sorry to say no photos. We were coming down from the mountains headed west to the flats plains. I am extremely color blind, but thus was a sight to see. We were not the only ones who stopped. YES, i will always see them differently now. And yes, I will seek them out. This has giving me the affliction he speaks of. It is unavoidable if you have given your attention to the lecture, you have it too. Fight the urge to speak of it to someone when you see the next rainbow, they are not afflicted. 👏

the way he teaches with love and fascination proves that he is a teacher by choice and not by chance

The most charismatic, inspiring, dignified, and elucidating teacher of physics of the 20th century. His methods of communication, his manner of educating are as charming as they are wonderful. Not since the great Richard Feynman has there been such a popular educator of physics. His videos will be enjoyed for many generations to come.

The name Snell (with double l) is an anglicisation of the Dutch name Snel (with single l). Anglicisation is like colonialisation. You want to impose your own culture on everything :-(

W professor

Anyone know where I can find a clearer version of this video?

Sir you improve my physics understanding thank you so much sir I want to be just like you

LEGND OF THE PHYSICS 🤩

Nice 😂

صحاب الباك وين راكم ؟؟؟؟ ني وحدي هنا سور

thumbs down for clickbait title/thumbnail

using this for my static mech class, I love the way he draws μ :-)

Nice in physics

Wait a second, I thought that all magnetic sources lead to B/r^3. What is this B/r stuff?

B é é só r

Parallel axis theoreme: Huygens formula

I was gonna watch this until I realized it offended my "Meth not math" approach to life.

Quite incisive circuit analysis 😂❤

To maximize the efficiency of laser energy delivery systems from the Oort Cloud to a celestial body, you can consider the following steps: 1. Efficient Photons: Optimize the generation of laser photons for minimal waste and maximal energy conversion. 2. Polarization Control: Implement systems to control and depolarize photons as needed for energy distribution. 3. Beam Focusing: Use advanced optics to focus the laser beam tightly, minimizing dispersion and energy loss over long distances. 4. Adaptive Optics: Employ adaptive optics systems to correct for atmospheric turbulence and ensure accurate beam targeting. 5. Energy Conversion: Develop efficient mechanisms on the celestial body's surface to convert incoming laser energy into usable power. 6. Environmental Considerations: Account for the potential effects of laser energy on the target body's atmosphere, surface, and ecosystems. 7. Safety Protocols: Implement safeguards to prevent unintended consequences or potential dangers associated with high-energy laser systems. 8. Monitoring and Feedback: Continuously monitor the system's performance and adjust parameters in real time to optimize energy delivery. 9. Research and Development: Invest in ongoing research to improve the efficiency and safety of laser energy delivery technologies. 10. International Collaboration: Collaborate with other spacefaring nations to share knowledge and resources, promoting responsible use of such advanced technology. These steps involve a combination of technological advancements, careful planning, and rigorous safety measures to maximize efficiency and minimize potential risks in laser energy delivery systems.

Back to school

This is a real physics lecture! Good explanation! I fully understand why MIT is the no.1 university in this planet. Unlike my university, the lecturers just assume you understand everything and go to the ppt very fast. At the end of semester, we just concentrate on exams and we do not know what we have learnt.

He is correct about the gravitational forces in the heliocentric model if it were real. The moon is plasma, so there is no gravity, only electrical forces. Game over

Great teacher

Incredible teacher. Very clear and logical explanations of the equations and measurement error. Coupled with a great sense of humour. The demonstrations are terrific.

Watching after 8 years from India

Osmmm❤

I was almost dozing off while learning this topic for the past 1 hour the I came across your class professor and I can't believe that this is such a simple topic thank you so much professor I owe you a lot! I really feel so jealous looking at those students how would it feel if I was in 1999 and watched your class live, indeed lucky people to get a professor like you, sir!

Is it really 1999 😶

❤❤❤

Thought he got crushed by the pendulum, after seeing "last lecture" and the thumbnail

If I nail my bachelor in chemical engineering at 37yo, w/o any books but your videos, I'll credit MIT in my thesis and give you a share of every of my income as a chemical engineer. And I'm UNCERTAIN it will happen and yet it will

I feel bad for all the teachers who taught me in high school and college. Nobody even comes close to what Prof.Walter Lewin was able to achieve in these 60 minutes. This is probably the first time in my life that i have sat through an entire lecture with my fullest and undivided attention.

Mathematics Is Like Art If Don't Use It You Lose It 😎

T="total time interval for collision". Initial momentum of particle: p={mV}→. Intermediate momentum of particle at t=½T: p⁰={m(0)}=0. Momentum increase through wall due to collision, in 1st ½T: p'={½Mv}→. Momentum value through wall due to restoring force, in 2nd ½T: p"=←{½Mv}. ∆p ="momentum transmission through wall" =←{½Mv} - {½Mv}→ =←{Mv} = ←{2mV}. Final momentum of particle=initial+change: p"'=←{mV}. ∆x="displacement of pressure front through wall" Χ=|∆x|="wall thickness"       |--∆x->| {mV}→|🧱🧱|  {m0} |---p'->| (wall displacement=dx→) ←{mV}|<---p"-| (p' flips to p"= -p' due to restoring force~ -{kdx}→=←{kdx})       |<--∆x | "Momentum transmission per second" = ∆p/T =←{2mV}/(½T+½T) =←{2mV}/(X/v+X/v) =←{2mV}(v/2X) =←{mV}(v/X) v is independent of V, as momentum transmssion to wall is via stress waves that travel at the speed of sound for the wall material. Wall momentum magnitude in a ½ period: ½Mv = mV So, v=2mV/M and ∆p/T =←{mV}(v/X). =←{mV}(2mV/MX). =←(2m/MX)mV². Density of wall=ρ=M/{Volume of wall} So, ρ=M/{XA}, where A= "total wall area". Now momentum transmission is: ∆p/T=←(2m/MX)mV². =←(2m/ρX²A)mV².

Imagine he forgot the initial condition…

It's more informative to say that the MAGNITUDE of Z, which is represented by |Z|, is equal to the square root term (sqrt of sum of rsquared and xsquared, which naturally computes to be > 0, but notice that the Z without the | | is of the complex form r + ix and is not formally > 0).

I would like to remind you that this lecture is downloaded from MIT OCW using Internet archive, Walter Lewin didn't upload this video, he just uploaded it on MIT OCW back in 2004.

Cant believe this is MIT lecture. He has given lots of math but not the physics concepts behind it. The hidden assumption in force and momentum relation is "mass is constant". Why force = mass X acceletation?. why not force=massXspeed?. School kids can learn better from standard physics books.

Amazing lecture!

I am very happy to get a practical knowledge which is not afford all the professor like uu... I really got that I want...

Sir salute to you

Am from Nigeria, I really enjoyed your video sir Llnp😇

The magic number: bigger gravitational earth can you hear me? I will make you a design made only of magnetic sands, no antiferromagnetics
