Sean Carroll has a gift for explaining physics, a wonderful sense of humour, even his voice is very pleasant :)

Sean is that rare combo of of deep science and superb public communicator. Science needs more like him.

Dr. Sean Carroll is an intellectual black belt.

The analogies in this lecture are totally new to me, and very effective. His portion of Field Theory is the new bar for all lecturers from now on!

your clarity in explaining things makes your lecture so addictive. i almost listen to this several times a week. thank you.

I love the fact that he worked in "Miracles" by ICP...the fact that Sean is even aware of this song is hilarious. Funny guy, obviously very brilliant

I think this is Sean's best talk. I've never heard Quantum Field Theory explained so well.
It's these sort of higher-level talks for the everyday physicists that I believe will lead to unified theory of all dimensions & forces.

I started to watch this casually but it grabbed and held me for the whole lecture. This is one of Dr Carroll's best!

I wish I was younger and (much) better at maths so I could be involved in this great work.

Worthwhile talk by Sean Carroll on the basic of QFT at a level suitable for high school students.

This guy is really smart! It's not just the physics; it's the spontaneous, resourceful humour!

I never imagined that a lecture about Quantum Field Theory would leave me in awe of the optical abilities of a frog...

I've watched this lecture 3 different times in other videos and it never gets old.

He explains so much, so well, with so little time. Particle at the End of the Universe is a great book. You know you're in Illinois when 1:06:00.

I'm a layperson. I found Dr Carroll's recommendation/insistence on viewing the quantum world as fields rather than as particles (apologies to the physicists who are offended by this inept phrasing) to be very helpful in trying to understand this topic.

Always a treat to listen to Sean Carroll, one of the best.

Best explanation of modern physics, clear and concise. Loved the humor too! Thanks Fermilab and Sean!

Great upload! I am so impressed with Sean Carroll. His talks always have a good pace and he delivers concepts in a direct and understandable way. I love his sense of humor too.

I have no idea what the heck Sean was talking about but I laughed so hard that it compensated for that.

Sean thanks  for this. I argued about this at school in 1975 and My teacher Dr Firscht said I didn't know what I was talking about. I now think I did.
