Quantum Field Theory visualized

Many thanks to my friend Thomas Harvey who helped me write this video. Thomas was my roommate during my Master's at Cambridge, he is now doing a PhD at Oxford University, and quantum field theory is his daily routine : www2.physics.ox.ac.uk/contacts/people/harveyt

Wow, someone actually described what spin is

Speaking as a physicist, this is SUCH an exceptional explanation of QFT.

As a visual learner, these animations were incredible and helped immensely. The writing was also crystal clear and paired perfectly

12:23 blew my mind because while it is useful to think of a string as vibrating at a particular frequency, the truth is indeed that any given section of the string is vibrating differently from the rest, and it is the synthesis of all those parts of the string at once which produces the final frequencies. Once of the best ways of describing wave function I have ever heard.

Excuse me YouTube, Why did it take 2 years to recommend Fermilab vids to me from PBS Spacetime and 3 years to recommend ScienceClic vids to me!? This is beyond superb content!

This visualization is so advanced, its like partaking in future starfleet academy education

This particular video was way too complex for me, yet it was fascinating to just watch and try to understand bits and pieces. It's incredible how even the most difficult type of information can come across to the most simple people, as long as its explained in a proper way. Good job

Best short presentation of QFT I've ever seen. And it fully complies with what Einstein once said: “Everything should be made as simple as possible, but no simpler.” Great work!

The animations in this video are extremely impressive. They present some of the basics of QFT, much better than many other casual sources. (and visualisations like this are also almost unavailable in an academic context as well)

You know, I'm a physics student, currently learning all of this stuff, and I've been searching on YouTube for months to find some way to help me visualize QFT beyond all the equations on my sheet. Well, that's the exact video I couldn't find, thank you so much for this amazing work !

I studied QFT during my master's for a whole year and the lecturer lost me quite early on in the course...This video presented a visualization and explanation of QFT in such an incredibly understandable way that much of the confusion in my mind was finally cleared up! Thank you so much for creating this video!

I just found your channel and I had to say this is the most fun I've had in learning and understanding at least specifically Quantum Theory, and I do mean fun. You come at it like we would have in college, starting by building the theory piece by piece. But your script and breakdown level made it the most comprehensive I've ever seen. Your pacing is also incredibly satisfying as you give time for us to process the new words and topics, digest them enough to feel like "I'm not 100% there, but let's trust the process" and then link the non-visual phrasing with the excellent visualization. This is an incredibly satisfying way to learn, for me at least. But your script writing and outline is a huge part of me coming away actually understanding this on a level I really wanted to when I clicked on it.

I mean, scary monsters are great and all, but it's this stuff that keeps me awake at night.

This is by far the best explanation of QFT I've ever heard. This video seems to go by very slowly, but in a really nice way. Dont know exactly how to describe it, but thank you!!

Why on earth is this channel so underrated?!

I'm a high school student and this video seemed interesting especially since i'm in my physics phase, and my mind is blown. That is so interesting, and i managed to understand most of it thanks to your incredibly clear explanation and visuals. I might have to watch it a few more times to memorize and understand it better, but it makes me want to dig even further into the subject. Thank you !

You just explained quantum spin in a perfectly sound, fairly simple mathematical context without resorting to the tired line "particles don't really spin, but you can think of it that way". I'm absolutely blown away man! Also, I'm a huge fan of how you symbolized conservation laws by their corresponding transformation symmetry in the appropriate spaces. Not super necessary to understand the content, but a nice little something extra for those in the know!

For a non-physicist layman, who just happens to enjoy reading and watching YouTube videos about it, your videos are fantastic. Great work. Keep them coming!

As a philosophy student this is fantastic. I have never considered paying attention to physics, but I understand how important it is to the world around us and the intersectionality between quantum mechanics and philosophical concepts has blown my mind. Absolutely fascinating, and you did a great job in making it super easy to comprehend. Thank you.
