I am a high school physics teacher. I would say this is the best animated video on Feynman diagram I have ever seen on YouTube. This will certainly be played in my lessons.

[dr_cheez]

this channel is like a crossover between 3blue1brown and pbs spacetime. altogether a better mix of the physics and math

[vjfperez]

Having spent a significant fraction of 35 years getting education in related STEM fields and having read many books or watched many popular science talks with famous people, I have to say you are the first to make it crystal clear.

My man, your animations interact perfectly with your explanations making very conceptually difficult subjects easy to understand.
Keep up the good work, we believe in you

[hotlinkster]

The animations are great, as always! And as someone currently studying these topics it's a great overview

[минусдваминусодинноль]

i really love how some parts of your videos are easy enough to get you interested (eg the animations), but also informative enough for you to come back to the video with more knowledge and still learn something new. and the more complex the topic is, the more times you can rewatch the video! honestly amazing

[hooya]

You guys keep knocking it out of the park! Amazing description, with no fluff. I've been consuming popular physics media for decades, and this is some of the best!

[pa.l.]

You are a gifted scientist, but also an artist. Rare combination of animator and physicist. Here is my praise for this gift:
You are destined for sparking a virtual qft and physics interest, much like the elegance found among the particles in our universe which you've animated so creatively. This video, as well the previous ones, serve to rekindle an interest in learning new physics that I never could grasp. Awe-inspiring content. Quantum Art.

Your accent and your voice are honestly unbelievably satisfying

[MrKreidel]

it's absolutely awesome how you squeeze such complex matter into 15 minutes.

[quanghaita]

As an architect who is curious about physics, I’m grateful of your creations: the combination of visualization graphic, your music, your voice and especially your own way of explaining. Thank you.

[JoshMeihaus]

It would be impossible for me to express how thankful I am for your beautifully-animated and clear explanations of these ideas. Thank you.

[jimstanfield]

This is, by far, the best explanation of QED and Feynman diagrams I have ever seen.

[TheyCallMeHacked]

I'm happy there is now an english version of this channel. I watch both, because I have the feeling that although both have the same information, I get a fuller understanding than if I were to watch only one of them...

[Bitmaker]

so what I'm getting is that there's an infinitesimally small chance of me just falling through my chair.

[okspaceman]

This is the best explanation of Feynman diagram on internet.

[bradbadley]

The momentum of the 'wave' pulling them together!!! Mind blown! Finally an explanation that I can grasp.

[FactsNReason]

This channel is amaze-balls:
1. Great summary explanations —not too complicated, not too simple

2. Great graphics and representations

3. Great connections between branches of science

[TheCobaqua]

Your channel hits exactly my sweet spot in terms of difficulty of material

[IKEMENOsakaman]

I failed physics while in High School. I wish you were my high school physics teacher back then.
