Lectures by Walter Lewin. They will make you ♥ Physics. I Would Like to purchase your full collection of videos and writes.

I have DVDs of all my lectures. I have only 1 copy of each lecture. I'd be willing to sell to you all my personal 36 videos of my course 8.01 for $7000. New copies can no longer be made. My extensive notes for each lecture - with time marks - are not for sale. I can send you a signed copy of my book for $30 + postage. Postage is $10 in the US, $30 to Europe and $48 to India. I will write a special note for you in the book. I will also include a signed colored picture of me swinging on the pendulum (with your name written on it). For an additional $25 (+ postage) I will send you a signed and dated 24x18 inch sheet of paper with my original handwritten calculations as I post on my Bi-Weekly Physic Problems. I will send you 2 such sheets for $35 (+postage). They are the originals - *thus one of a kind - there are NO copies.* You can see 3 such sheets in the video in which I solved the yo-yo problem of 2 weeks ago: ukposts.info/have/v-deo/rXGAh4Gim4ypxJ8.html When you transfer the money to my PayPal account let me know your full name and your address (make sure it is correct and complete). Keep in mind that PayPal charges 6% for each transition. PayPal: lewin-physics@physics.comcastbiz.net

"i only have to act enthusiastic one time, film it, and then play the lesson to next year's class."

Great!

we are all lucky!

Yo

He is not a professor, he is a MASTER

Technology has made all of lucky

we are all lucky, because we can watch his lesson from UKposts.

Great to hear!

I had a craze to enter IIT,but it was a difficult task to crack the entrance test at that time.There were several ifs and buts.Now in this digital world,everything you get at the click of a button The lectures of the greats like professor Lewin, you could not imagine in the past.Long live the professor so that we could here more about physics.

:)

Yeah

WanderAbroad I beg to disagree. there are many theories for which there is not, or at least for some time there wasn't, a clear application. This doesn't make them useless.

@WanderAbroad i am british. educated britons know all about history and politics. that's why we are a nuclear power with satellites in orbit that can see into the earth and show us where the minerals are. that's why our diplomats have fingers in all the pies. that's why we control oil in Nigeria and gold in Ghana. that's why South Africa is ours (soon). no revolutions or great depressions setting us back. British American Tobacco. Anglo Dutch Oil. Lloyd's. BAE Systems. East India Company. Professor Lewin knows all about history and politics. that's why he was a top-level academic with tenure.

If I design another way of teaching the same concepts in physics u would fall of ur chair. Hint; in my teaching method no classroom no sitting no instructor or very little of it. All action.

and i was about to go to bed

O S V S L bro I’m high as well watching this while procrastinating for homework what the hell lmao

O S V S L Heh heh heh.

What u mean? I'm not even in school! 🤣🤙

It doesnt mater is you smoke weed, Mr. Lewin has captured your attention. In the society we we live in now. Its nice to see a true hero, someone who loves learning and education. I smoke weed, and I find myself being inspired by Mr. Lewin. 1.8 million views. Thank you kind sir.

Always so wonderful to have an excellent, passionate teacher!

I am watching second or third time again, I don't know why either. Very Non-intuitive.

My guess is the youtube algorithm, they have discovered after x time a significant portion of people will rewatch something because most often they forgot they watched it and will make the same decision like the first time (to watch it). I have fallen for this several times.

My guess is people are looking for revision material before impending exams and those extra views cause the algorithm to promote it as a recommended video ...

Agreed

i love it

@@daddysnip6397 I too love it when teachers leave their students feeling helpless! After all, actually understanding the content of the class is for losers!

@@Tom-cn4cm Classes are to learn, not to spoon feed you. The thinking and understanding, has to be done by you alone

Hahaha a good one

@@Tom-cn4cm teacher can't make you learn something. They can only present you the matter. Obviously the presentation's quality is of importance but only you can do the learning.

Did you make the PDF? pls do!

mind blown

... the unchanging nature of the knowledge does not make this lecture out if date!

Look up "Power Ball Hand Exerciser". Its a dual axis Gyro that is powered with a simple flick of the wrist. Try and put coils and magnets in it to make a hand held power generator.

40:25 i did that when i was 10 years old. Not sure why but it was fun at the time. I used to take ice cream buckets with a funnel stuck through with a hose on the other end. Fill the funnel with flour with a lit candle beside it and snap the lid on and blow. Nice flour explosion. Ya 40 years later and all i do is go to work so my kids can sit in classes like this. Well keep up the good work A+

the physics department at mit had, and has, quite a few outstanding professors. perhaps the best of all is mehran kardar.

You are so welcome!

Thanks Miguel

My favorite Feynman clip: ukposts.info/have/v-deo/h3xnYa5npKWV2I0.html

How is class going I’d imagine phy2 is coming best of luck with electricity

God bless you!

Also, thank you for making these videos available to the world!

*taught (fixed that for you)

@@gabriel1812 tnx lol, I guess my English got a bit sloppy x)

Non-intuitive physics? I sense pretty a lot intuition behind it.🤔

:)

And it even tells you why you want to lean to the left in order to turn left, because that applies torque to the wheels which turns the axis of rotation to the left. :D

Yes indeed!!!

There's more to motorcycle steering dynamics, it's actually pretty complicated. In addition to the gyro force, you're also deflecting the support point (wheel contact to road) from under the center of gravity, which also tilts the bike. The actual change of direction, and the amount thereof, is then another matter entirely.

Not to mention the decaying circumference of the wheel as you lean further over causing the path of the bike to follow that direction

Wow, thanks!

😂

BEST DAY OFFF MY LIFFFEEE !!!!! WALTER LEWIN REPLIED !!

😊

Great video. Walter Lewin is amazing! In India too, there are some amazing teachers and I am lucky to have attended lectures of a couple of them, but yes, these kind of teachers who don't just speak, but 'show physics' are rare in every country, including the US :)

@@sagarshenoy You're right! Passionate teachers are rare in every part of the world.

Thanks for you kind words

:)

+mizar52 Yes I totally agree with you. I loved the experimental side of physics but because the teachers had a very dry way of showing the maths I quickly became confused and turned away from the field. I regret this now. The internet has shown just how good instruction and teaching "Can" be. What stuns me is I had assumed that modern teachers would watch the innovate ways of teaching on the web and copy them. But the majority do not. they trundle on with their archaic outdated methods and wonder why most students get bored or left behind. People in charge of education have a lot to answer for. Thank you for your passion Professor Levin.

salut mon frere

Zzz... useless! Just like you need math to calculate how long you going to stay airborne while jumping in the air....

Electric Experiments Roobert33 6

Pure awesomeness.

But at 18:51 the experiment is non-sense!

You do every time you ride a bicycle. It keeps you up.

This is not a high school I guess?

@@gustavtd nope it's MIT

I had a similar thought. The court wizards were probably just physicists. "Me lord! Check this shit out! Wheel falls, right? Makes sense. But now look at it! STAYS UP ON ITS OWN! MAGIIIIICCCCC"

@@whoopshoopadoop8900 Burn the Whitcher!

you are exactly right. !!

Yes and I am thinking that; still today; this is a mentality state that humanity is stuck on.

Now i know why witches rode broomsticks not bicycles

Excellent!

@@lecturesbywalterlewin.they9259 hello sir, are you from the netherlands?

*34 is a perfect age to start a new life*!

HI That would be PRECESSION!!! Shalom to us only in Christ Yeshua

Just pointing out how much a loser the hollow cylinder is in total.

Wow, thank you!
