The editing, the narration, everything about this video was great.
-
I've heard this topic explained maybe 10 times, but this time it actually made sense, great work!
-
This isn't just an informational video, it's a visual treat. Thank you for this immense gift.
-
During my Master's in Theoretical Physics, I used to watch David Tong's lectures on Quantum Field Theory. Now I am again reminded of why I did that. He is such a great communicator!

Beings living in dark matter clusters: Why the heck is 5% of the universe missing?

I love how physicist will always end explanations with: "... and we have no idea why that is". Even for my course on intro to the universe, I had asked something along the lines of energy dispersion right after the big bang, my prof was able to describe it perfectly, but just ended with: "... but don't ask why, no one knows!".

Can we all take a moment to appreciate the extreme hardwork done on the animations here alongwith the mind-boggling scientific and cosmic terminologies?
-
Fantastic explanation of the most complicated subject known to humanity. I still feel like I don't fully understand it, but I can at least grasp the main parts of it. Quantum scientists are undoubtedly some of the most important and magnificent people in the world, their work is (literally) everything, and they are the ones moving this species forward every single day.
-
This's by far the most interesting and scientific way to teach about the particles, I have ever seen. I mean I'm an engineer and mostly doing programming, but I like watching science and physics in my free time. That way it was described and animated shows clear knowledge in teaching something hard in easy ways. I will definitely subscribe! Thanks and keep up with this work!
-
Wow, it's David Tong himself. He has a really easy to aproach lecture note on Quantum Field Theory that I appreciate a lot.
-
I have been a physics enthusiast for most of my life (26yrs old now), and I’ve watched many videos explaining these principles, read many articles etc. And I have to say, this is by far the best explanation of the standard model i have come across. Job Well done👌 Subscribed.
-
This was super accessible and very well narrated. I still get about 3% of it but it is still a fascinating watch. Thx!
-
Sir, I have never had a clearer understanding of how everything fits so beautifully together till I saw your amazing Video Explanation. I wish they taught like this in schools. Reading it in a physics book doesn't do justice at all!!

This is just so awe-inspiring. To think that we humans have unraveled reality to this point and discovered so much about our universe... It's just so surreal. And there is still much more to we have yet to understand. "The culmination of 400 years of science", truly gives me perspective on the effort all the brilliant minds of the past and present have given towards advancing us to the future. I cannot help but respect their drive and curiosity to peel back the layers of reality and see what truly lies beneath. I have nothing but respect to everyone who has contributed and is contributing towards our further understanding of the reality we live in. 13:24 and onwards reminded me of a saying I heard before: "It's better to have questions we can't answer than answers we can't question." This mentality of scientists and researchers is just so inspiring. Thank you for all that you people have done to create all the things most of us take for granted today. Having been born in this age of technological advancement is not so bad at all. I'm excited to see what the future will bring towards scientific discovery.

I gained a brain cell.

Prof. David Tong! The legend himself! I can't believe I was lucky enough to have met him in person. Thank you for the immensely beautiful video.
-
I have watched over 30 videos discussing these particles but this was the only one that left me with a crystal clear understanding. Great work right here!
-
This is one of the best videos that provides a clear picture of the Standard Model of particle physics. Thank you, David Tong!
-
This is THE MOST beautiful and THE MOST clear video I’ve ever seen on the Standard model! I have never understood the standard model to a 100% until I stumbled across this video. Amazing stuff. Keep it coming. Thank you.
