hows this 4h ago if video is 1 min ago
damn holy fyp pull
How is this 4hr ago. Was it members only ?
how this 4 hr ago tho the vid just dropped😭
There´s a Chilean poetry genius who named his work as Anti-Poetry, he was a Physics University professor. Nicanor Parra.
Watch this for 35 minutes. It was beautiful, I understood 5% of it.
Does this semitry give rise to a plank constant in each quadrant also, it also kinda looks like a lie detector.
Seminar proof reminds me of zero trust architecture
I’d love to believe it but these mathematicians and physicists putting real life into numerical form don’t show or prove the reality of physics in my eyes. You assign enough variables to any equation and anything can make sense. We’re missing way more about the world than we know. Nobody has an equation that works for everything yet because it isnt ever right. We find something that works for many things and assume it means the final answer is close when it could be completely different
Fascinating – was Dirac impulsive 😏
❤damn !!
I truly wish i understood these equations and how they work….
Nice
The video ends with a giant FU towards Dirac and his wife: she lacked status, he lacked life. I find it strange that the video maker and much of the audience consider that statement cute
So spin emerges as a natural consequence of imposing the same order for the time and space derivatives, being that spacetime is a physical construct and not two separate entities? And matter-antimatter is due to the positive and negative solutions to Einstein’s special relativity energy equation?
too many simplification makes the lectures understandable, but you have to be very careful in order not to make it in the wrong way leading to misunderstandings. Other wise I enjoy relativistic quantum theory. But there are too many missing parts.
Fock it.
Perhaps, somewhere in our universe, is a concentration of the corresponding antimatter, making up planets, stars, etc…
Maybe you should retire indeed. This is probably your most senseless video..
Typo
It sensible
32:14 You really believe that all this beauty came from a bang and by random chance? I think there is a creator and God made this amazing universe with all it’s complexity in the visible and quantum physics world. Everything works so precisely and hand in hand with everything else. All Glory to Jesus for that 🙌
how many human in this world can actually understand this?
The power of two bfdi 15:20
Brilliant ending to the video
