This is brilliant. This professor explains things extremely clearly.

Que nivel de clase de este profesor . Orgullo peruano .

[marcocarrasco]

Barton, el único estudiante en la historia de la UNI que se graduó antes de terminar su carrera.

[moinmalik]

Besides the wonderful clarity in his lecture, I am amazed at his very clear, beautiful, and organized writing on the board.

[mayimbu]

El mejor alumno de la historia de la UNI.

[manaoharsam]

Great Teacher. Takes time and explains well. Defined indeterminism very clearly.

[pity]

Well spoken with excellent handwriting. A rarity among physics professors

This lecture has nothing to do with me but I became entranced with his style and voice! And I actually learned something new in quantum theories. Thank you Sir.

I can tell he is a good teacher because I understood this little "lecture" better as when my teacher taught me the same subject, even if my teacher spoke my first language (french), and this teacher speak english, that is harder to understand for me.

Thank You for making it understandable !! I am a software engineer in network domain. I just watched these videos(first 4) out of curiosity, and I was able to understand a rough picture of what's trying to be conveyed. Last time I studied physics was in pre-college days.

Such amazing job Mr. Zwiebach! Thank you...

This guy is really good. A brilliantly clear explanation. Moving slowly enough for a dummy like me to grasp it. No wasted words.

[keepgoing]

there's something about writing on a chalkboard that just makes it much better than presentation slides as a teaching medium for showing equations

[ralphdams]

What a wonderful teacher you are, if I may say so. Thank you for sharing this lecture with the public. 🤓

"That's what polarizers do for a living" :)

[KipIngram]

It's important to point out that when the polarizer is aligned at some "middle angle, " then the light that comes out is NOT identical to the light that went in. Not only does only a fraction of the light come through, but that fraction now has polarization aligned with the POLARIZER, not aligned as it was going in. The polarizer "turns" the polarization angle so that the outgoing light is aligned with it. This raises the fascinating situation where you can put two polarizers at perpendicular angles together, and no light gets through. But if you then slip a third one in between the first two aligned at, say, 45 degrees, then suddenly some light does get through.

I definitely agree when you mentioned that it's good to learn from physicists and it's useful that we have them, it is good to make new explanations for what comes next.

Brilliant lecture given by Barton Zweibach Sir

[cookiedog]

This professor is outstanding! It’s been over 30 years since I studied QM/QP. Never used it so forgot it. Great reintroduction. Thank you sir.
