Previous Episode:
Anti-Matter and Quantum Field Theory
   â˘Â Anti-Matter and Quantum Relativity Â
Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet itâs also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, incredible discoveries have been made. Its wild success tells us that the mathematical description provided by quantum mechanics reflects deep truths about reality. And by far the most successful, most predictive formulation of quantum mechanics is quantum field theory. It is our best description we have of the fundamental workings of reality. And the first part of quantum field theory that was derived â quantum electrodynamics â is the most precise, most accurate of all.

Very nice job on the animation of the array of oscillating springs eight minutes into the video.

Paul Dirac was underrated

I don't understand 90% of what he is saying but I'm still watching. I'm hoping that I'll eventually understand it if I watch it enough times. :/

As an engineer who has always been passionate about math and physics, I was intrigued by modern physics, despite neither relativity nor quantum mechanics were part of any course syllabus at my university. I studied these subjects on the side and found them really inspiring, I would go as far as to say that they gave me a novel perspective on life itself. That prompted me to create some online courses on Udemy on Quantum Mechanics, Quantum Field Theory, special and General Relativity. Itâs not my job of course, but I love talking about these topics while using some mathematics for âintuitionâ.

"to do that we are gunna need another genious."
pls be Feynman, pls be Feynman.
"we're gunna need Richard Feynman."
YES!
"... and we're gunna need another episode of spacetime."
NO!

LOVE the way you phrase some things: the math of QM "reflects" deep truths about the universe; QFT "describes" particles as vibrations in fields. You don't lead the audience to think that's truly (whatever that means) how the universe is, but that it's the best description we have. Masterful treading of an exceptionally fine line. Good stuff!

3:47 "let's go quantum"

That's when i lost him

Can anyone recommend a good quantum mechanic? Mine is ripping me off.

One dislike? Must be god. "Damn those fuckers are figuring that shit out too fast"

3:38 as an audio engineer this sentence just completely rewired my brain i think

Wow, you explained this in such a way that I finally understand it . . . I'm just messing with you! I'm completely fucking lost.

next stop quantum gravity???

I am four years late to this discussion and totally enamoured by it. Thank you!

Every episode seems like a christmas gift, love this series

Now I feel that PBS Space Time is back to life. Thank you so much for this quantum series. I love PBS Space Time

I had to read Nueromancer by William GIbson 7 times before i knew what it was about. Now I consider that casual light reading. Even though i still do not completely understand it I get enjoyment and new ideas, rather than stress, out of reading it again. Keep reading! it eventually works!

Another week of fine shower thoughts ahead of me. These recent Space Time episodes are hypno interesting. Good work!

My FAVORITE youtube channel of ALL TIME!!! I love PBS Space Time! I will not have had my fill of this channel until literally EVERYTHING in the universe is explained one video at a time!

I'm amazed at how well this is explained, usually Quantum theory baffles me very quickly but I was able to appreciate this whole video, thanks!

This is one of the only shows on youtube I consistently watch every new episode for. I have a BS in physics but none of my professors ever really "explained" these concepts beyond just how the math works.
