I appreciate these lectures being online.

[mrsulaman]

I would like to compliment the camera man for his fine work. Also whoever is responsible for recording the sound did a great job. It's so important to be able to hear and see these lectures clearly. My thanks also to MIT for making this content available.

im 13 and the way he teaches and breaks it down is truly magnificent and fascinating how everything works

I love this form of explanation. It is so complete. And I love that the facts and reasoning are explained in a human-centric simple form, where so many others throw a bunch of fact at the screen. Thank you! I will use this information in the most powerful way. I have tried to wrap my head around the supposedly simple idea of linearity for a long time. Somehow this shifted me over my preconceptions.

There are some people who are perfect communicators of complex subjects.

My calculus teacher, Martha Kasting, was one such person. She would smile the entire time as she described Green’s Theorem, or she would say, “Isn’t that a pretty equation?”

Dr. Zwiebach is another.

I'm Sido Rodrigues Brazil I really like Quantum Physics Classes. Very important to know quantum physics. Teach everything the universe knows and you gain self-knowledge about everything. Great series of really useful lectures on quantum mechanics. I am also very grateful to MIT OpenCourseWare and Barton Zwiebach... etc...

I feel illuminated. A clear and concise lecture by a lecturer who comes across having an authentic passion for learning and understanding. Thank you 🙏

[chrisl]

As someone who works in (classical) fluid mechanics, I can confirm that it's very very nonlinear.

This is actually an excellent class. It worth's its length in Gold. Thank you very much

[prabudeva]

I'm from India.... great thank you mit gives the online courses...little tweak are arises...but most of the phenomenal are not predicted..which means my life time scenario is the one of the examples...some atoms are vibrated...but no losses. After some times the illusion are visible... 🤔

First time I’ve ever heard the process of QM explained outright, every professor I’ve ever had on the subject just jumps right in and it’s hard to grip without foundational information.

[karthigamanivannan]

thank you MIT AND ALL FACULTIES FOR PROVIDING INTERESTING LECTURES ON QUANTUM MECHANICS...

[RomanBraixen]

Nearly 200, 000 views on the first video, and the second video only has a quarter of that? Shame so many people gave up already

[MikeDbean]

Thank you. Great teacher. Easy to follow.

5:13 how is Hamiltonian operator linear? Since it also contains potential energy term which need not to be linear.

[FredBakker]

Mister Zwiebag, you absolutely rock! Explaining complex stuff simple is a trait of true genius!

[fujiexia]

Very excellent open course on QM, thanks MIT professor!

[MysticDreamer]

@ 9:30 he talks about Schrodinger not knowing what the wave function is. How did Schrodinger come up with this equation in the first place. Professor Zwiebach doesn't offer an explanation of how Schrodinger came up with this equation. But Schrodinger must have had reasons.

[kostasargiris]

Very good teacher!! I have a question : 3:34 Why x squared is not a linear function?

[arushaacharyya]

Where and how does the non-linearity get introduced in classical mechanics when quantum mechanics is all linear?
