Nice timing, I was studying about Dirac cones

Thank you. I was looking for that. What do you think about the future of physics in the Middle East?

The bot voice is subpar. You get a C- right off the bat. Otherwise, pretty good video. Phenomenal video of the man himself. Stupendous! Thank you.

Thank you for your feedback! I hope the AI voice generator will improve with time.

yes, so annoying that I stopped listening after 30 seconds.

Please scrap the fake voice and get a human to read a script, even if there are occasional stumbles.

@@professornanoscience Please cease to use AI to generate a "voice": just stop it. An actual human voice is far preferable and would greatly improve your video, which is otherwise very good.

At least the bot stumbles in amusing ways. "Derek sea".

- FANTASTIC EXPLANATION/PRESENTATION (assuming all aspects are correct - which, though I have considerable relevant prerequisites, I cannot fully vet). - As for the bot voice, I find it "acceptable". Also, I'm assuming this is from a human script, not AI (correct?). - I was aware that the Dirac Equation predicted anti-matter ("positron", specifically), and even that it was a result of there being two solutions - but, I did not know why this implied anti-matter. Now I do :) Thx. - And, I did not know Dirac's full motivation: specifically, his objection to the Klein-Gordon formulation, and his insistence on adhering to the Schrödinger Equation, and Heisenberg Uncertainty Principle. Now I do :) - Also, inclusion of video of Dirac lecture is a nice touch. - Finally, the graphene example, including discussion relating the Dirac Equation to it, along w/ ongoing research/experimentation, was very interesting/informative.

Thanks for the feedback! On your question, yes, I wrote the script... luckily generative AI is still not able to do this, else all teachers will be out of job :)

Quite nice review of the math and thinking. I can now see how Dirac did it. Didn’t really understand until now.

Nice talk. Some beyong my knowledge. Q: What's the potential of Graphene replacing Silicon chips.

@professornanoscience 5 ай бұрын

Graphene does not has an electronic band gap, so it cannot replace silicon transistor. But there are other 2D materials that are quite promising.

From 15:40 to 17:07 can likely be where gravity is formed. By there being pocketed positive energy states among- between some of the empty spaces in the negative energy states. Upon the two now there attracting so knitted, gravity is the biproduct. Gravity itself grows from these countless + - states thus unto attracting itself-- thus no longer needs the negative/positive energy it began from. (Gravity leaves the nest) Yes for it to form, there must be a positive energy- filling in that say, every 137th empty space among the negative energy states.

Xcelent lecture. Bit, what about the charges of the oposite carbons of the hexagon? Adjacent carbons may stabilize 1electron, but for Au it is possible to host a single e-rich metal. ¿...?

Great work! At 11.53 the Dirac matrices are defined incorrectly.

You posted the MATLAB script. Did you say you had a script in mathematica also?

2 mistakes in 1:30, the Schro. Eq. Describes hydrogen ONLY (many body hamiltonian after), the First and second part of 4 spinor are electron and positron in VACUUM, in an atom the full 4 components describe ONE electron. But beautiful vidéo otherwise ❤
