Quantum Fields: The Real Building Blocks of the Universe - with David Tong

According to our best theories of physics, the fundamental building blocks of matter are not particles, but continuous fluid-like substances known as 'quantum fields'. David Tong explains what we know about these fields, and how they fit into our understanding of the Universe.

Thanks to our community, we now have Galician subtitles for this video!

Ri please, give this man another chance to talk more about others subjects. This lecture was amazing.

This man speaks with such an enthusiasm that he doesn't seem to be a theoretical physicist......he seems like the student whose mind is still wandering with questions and doubts on the concepts of physics ......the way he speaks is really amazing and the thing he did with the magnets in the middle of the lecture was something we all did in our childhood and he still has that energy and curiosity about something is really deeply hidden.

I planned to only watch the first 10 min or so but got hooked throughout the end of the talk. What a nice a clear introduction of the topic by telling and combining all small, meaningful stories together. Just one of the best lectures I can think of......!!!!!!!

[@iumiforgot]

This has got to be the MOST concise explanation I have ever heard of such a convoluted subject

[@Ambienfinity]

I watch a lot of physics and cosmology lectures, and this is one of the best I've ever seen. David's enthusiasm and knowledge are brilliant.

I wish I got a physics teacher like Prof. Tong when I was young, he motivated me to study Physics in this one-hour lecture ! Thx Professor !

[@Jiminio21]

The best 1 hour i had on KZbin. I studied mathematics and finance but my big love is physics. That session has broaden my horizons toward my big love. It made my whole understanding of the subject solid and explained a lot of issues that I had on my mind toward it. Physics is the past the present and the future. Thank you sir

[@vancouverterry9142]

Ahhhhh, what a great teacher! Men like Professor Tong can lift up an age! And to have Royal Institution lectures by such brilliant individuals available free online is really the height of civilization.

How I, a student of Persian literature living in Iran, was fascinated by this guy's lecture. I'm truly astonished that I actually understood most parts of this, and really, really enjoyed it. Lots of love from Iran. Thank you sir. You truly deserve Faraday's throne. ❤️

[@ImranSahir1]

This is one of those lectures that you think you'll see for first two minutes and then the two minutes stretch up to an hour with some weird space-time magic. Fabulous!

[@uzulim9234]

Love David's lecture notes immensely. He packs in a great amount of intuition, insight and precision.

[@w0mblemania]

There is something magnificent, magical, haunting about seeing someone deliver a lecture at the same desk as Faraday. Between Faraday and now, there have been tens of millions of deaths in war, the Holocaust, untold suffering. But there is also an unbroken chain of scientific discovery.

[@let4be]

Absolutely brilliant lecture - exactly what I was looking for! The shine in the lector's eyes and his enthusiasm clearly shows that he adores his job and physics! Thanks for this generous contribution to the spreading of knowledge :) I can only imagine how many young minds will get excited watching this, most certainly it will influence path of some people :)

[@aeinapco]

I LOVE how passionate he is!!!! You can feel his passion radiate through him... love love love this. Powerful. Incredible.

[@marie-christinavirago3909]

Such remarkable verve and excitement for something that was almost destroyed for me by musty teachers. The swaying dance is magic indeed. THANK YOU!

[@ergbudster3333]

This proves what I've always believed strongly since university: that a really smart person can explain things. A smart person who really understands things can explain things. And even the things that can't be explained can be made tantalizing and invite us to learn more. Wonderful lecture. Well, as so many are on the RI channel.

[@tomneedham1937]

I have a "working knowledge" of theoretical physics from my undergraduate years of long, long ago. This lecture is the VERY BEST lecture I have ever listened to explaining, in simplistic terms, what the current, cutting edge frontier pf physics is all about.

[@metameta1427]

This is one of my favorite presentations on this channel. I come back often and rewatch and never of tire of the presenter's infectious spirit and detailed explanations. Thanks to RI for being one of the best channels on this platform.
