4. Coupled Oscillators, Normal Modes

[@ricahrddowner6016]

42:30 is when he begins using motion equations and starts applying classical mechanics. Everything before are wonderful physics demonstrations for concepts in understanding.

I’m happy to watch your lecture through youtube. I learn many things from your lecture. Thank you.

[@manaharchowdhury2402]

The beauty of physics. Oscillation is everywhere. Beautiful lecture

[@berketozlu]

This lesson is pure diamond

[@iosuegea9607]

What an amazing teacher.

[@nutandas4413]

Thank you sir for this amazing lecture.🙏🏾🙏🏾🙏🏾

The way that I learned the eigenvalue equation from my textbook goes like this: Det( K - w^2*M) = 0 But he defines it as: det( M^-1 * k - w^2 * I ) = 0 They both work the same way but i think it takes more time to solve it through the first way

[@tanmaychandane8279]

not really. taking an inverse takes time. especially for a 3x3 matrix. now its a different thing if you work out enough problems you see only diagonal terms contribute in M matrix

[@ankitnmnaik229]

Can u tell me which textbook

[@voxeledphoton]

awesome lecture! Love watching stuff like this at 3am. Kinda want to see if I can apply these to what I've been messing with in cymatics.

thanks prof, amazing lecture

4:42 interesting way to see it, thanks 🙂

Does a coupled oscillating system always become nonlinear?

[@Manhar-zr3eg]

Thank you sir for such great helpfull lecture

[@VanillaBean15]

You are a really good teacher!!!1

[@steveying1305]

great explanation...........i truly wish i could have u instead of my teacher

[@ricardocesardasilvagomes9549]

Aula maravilhosa!

[@commodorekitty]

Good lecture. Thanks for uploading.

What is meant by Initial phase difference of the pendulum is 0??

46:28 When an asian whilst doing math say's "no magic" you better believe he's about to do some wizard stuff.

[@vivekpanchal3338]

Great 👍🏻 👏

[@adriadi4986]

Is there a way that all learners of this course can come together to discuss on the topics and have a recitation maybe?

MIT needs a new Walter Lewin

[@tmsyou]

For this subject you actually have lectures from Walter Lewin and personally as someone who loves his lectures I don't believe them to be much better than the ones from Dr. Lee. This is a very mathematical subject and I think this professor has some good methods to keep you entertained and focused. Also through this course there are lots of good demonstrations for you to get a grip on the motion you are studying.

[@primenumberbuster404]

​@@tmsyou agreed and it's relevant 5 years after too. Nothing beats it.

[@marioo5856]

well

[@Madhabhupi]

Sir pls. Sir note writing video uploaded pls. ... I see too note sir ... Argentely note pls uploaded coupled oscillator chapters...

this guy is excellent.

His accent is soo weird

[@pullingrabbitsouttaahat]

Too Many OK's , Misplaced Demos and Offbeat Laughs Killed Your Lecture. Got to Improve Dr.Lee. Good Luck !
