7:00 (When very good physicist are wrong, they are not wrong for silly reasons, but they are wrong for good reasons, and we can learn from their thinking.) I love it!

I am not mathematics major. But whenever I watched videos regarding math it brings Peace in heart. I don't know why

gauss hated the name imaginary, because it's confusing.He suggested to use lateral, because the complex number are represented on the lateral axis unlike all other numbers.

Barton Zwiebach is peruvian. He was born and studied school and electical engineering in Lima, Peru. As a peruvian I feel so proud of him.

I had to learn this by distance education (1992) before the internet and always struggled. Barton makes it seem so easy. What a fabulous lecturer.

I clicked because I thought he was a young Harrison Ford. Now I know how complex numbers are crucial part of wavefunctions in quantum.

If I ever strike it rich, I would love to go to MIT to study physics at leisure with amazing teachers like this...

I am a teacher at the beginning of my career. That was a very inspiring explanation.

As a peruvian I feel proud of Barton, he is the best student of the National Engineering University in Lima Peru

Very nice short note on complex numbers. A great professor tells you much more than just writing down those dry equations.

Honestly, this was probably the best introduction to quantum mechanics i'ver ever heared. Before you get to this whole superposition shit and stuff, first explaining the fundamental maths behind it, which by all means isnt that hard to not teach it to students. Great job.

I’m actually an engineer but this is the first time I understand why we really need the complex numbers Thank you sir !
