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

I’m happy to watch your lecture through youtube. I learn many things from your lecture. Thank you.
The beauty of physics. Oscillation is everywhere. Beautiful lecture

This lesson is pure diamond
Thank you MiT
What an amazing teacher.

Can u tell me which textbook
Thank you sir for this amazing lecture.🙏🏾🙏🏾🙏🏾
great explanation...........i truly wish i could have u instead of my teacher
thanks prof, amazing lecture
I am form india ... thanks for MIT classes
India ❤❤❤❤
Thank you for the class, it’s rlly helpful
Aula maravilhosa!
Thank you sir for such great helpfull lecture
You are a really good teacher!!!1
Good lecture. Thanks for uploading.
Does a coupled oscillating system always become nonlinear?
awesome
46:28 When an asian whilst doing math say's "no magic" you better believe he's about to do some wizard stuff.
Great 👍🏻 👏
What is meant by Initial phase difference of the pendulum is 0??
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 agreed and it's relevant 5 years after too. Nothing beats it.
👍👍👍👍👍
well
Sir pls. Sir note writing video uploaded pls. ... I see too note sir ... Argentely note pls uploaded coupled oscillator chapters...
Work on english
Notes are in the complete course in video discription.

even mit has boring professors!!!!
this guy is excellent.
His accent is soo weird
Too Many OK's , Misplaced Demos and Offbeat Laughs Killed Your Lecture. Got to Improve Dr.Lee. Good Luck !
