The Biggest Ideas in the Universe | 17. Matter

I kind of like having my own space. So definitely more of a Fermion.

its a great pleasure listening to all that complicated stuff so beautifully brought down to earth. Thanks a lot.

The universe is full of "doesn't matter"

I’m proud I guessed the relationship before I was told

Absolutely brilliant

Matter is not idea :-)

You’re so awesome Sean!!! Love you buddy!!! 💪🏽👍🏽❤️

I believe this serie of videos will reach the same status as "The Feynman Lectures on Physics" for the next generation of undergraduate students. Lucky guys :-)

Awareness is known by awareness alone.

Do atoms produce a standing wave?

Thanks Sean.

I hope you're not mad at me but I can't watch this with that background over the bricks behind you it's wicked wicked distracting and I really don't like it

awesome. So cool. Thx !

Not absorbing as much as I would have hoped, while falling asleep.

A Matter of Fact! 😆

Thank you your lectures (vlogs) are simply fascinating.

Not sure a brick wall is a good choice as a back ground for a teacher? Re :Pink Floyd's - The Wall....

Thank you for the 360 degrees user friendliness. It adds a lot of charm to your way of explaining. I wish you to not talk and write at the same time more often. I'm curious how do you manage to keep your eyebrows calm when that happens? Have you trained to keep friendly facial expression so your student keep listening? :-) One of the greatest teachers in the world! For sure. Thank you for your Mission!

Sean, thank you for that explanation of spin as the angular momentum of the quantum field and for the discussion of spin zero, integer and fractional in the context of Noether’s conserved quantities. It has never been explained so clearly to me before, despite having a PhD in theoretical physics. What I like the most about this series is how it never takes the shut up and calculate road that so many professors take, and instead takes the time to explain what it all means, and calls out common shortcuts as inaccurate.

Sean, these videos have been absolutely amazing. Exactly what I’ve wanted to know about the way these things work! Thanks so much!

Amazing thank you so much

Prof. Carroll, you are an extremely gifted teacher!
Thank you so much for all your effort to put this series together.

Hi Dr. Carroll, can you plesae do a video explaining about the myth of "warp speed" that we keep seeing in movie such as star trek and such? I am very curious what's the correlation between gravity and electrons?

We can't squish a table, but does the table eventually degrade or lose its energy or charge over time if it's protected by environmental factors?

Today I learned the difference between "squashy" and "squishy".👍👍💙💯🔥

Sean Carrol: “Here are the secrets of the Universe.”
Me: “Ahhh, pretty cool pretty cool.. 💁🏻‍♂️”
Sean Carrol: *Holds empty mug and rotates it with his arm*
Me: ....... 🤯🤯🤯.......

"Why aren't atoms squishy?"...ahhh...that exam question we all dread!!

I miss physics lectures.

One small correction: the example of the electron going through the Stern-Gerlach experiment is not correct. As it is a charged particle is it subjected to the Lorentz force which will distort the clear separation in 2 discrete states. The experiment is usually done with charge neutral particles such as silver atoms.

I'm going through some health things right now and the drugs give me weird and intense dreams. When I listen to these lectures at night somehow that fades away and I have mathy dreams instead, sleep longer, and don't wake up as often.

One of the few people who can pronounce et cetera properly - its annoying to hear eck cetera...

You know what I love about physics is that you almost gain a sort of x-ray vision in a way, you see through things.

Thank you professor Carroll.

been a fan of Sean's for a long long time. He did a great interview with Joe Rogan years ago that was fascinating and I hope connected with a audience that doesn't typically listen to someone like Sean Carrol.

I follow those lectures for a good number of month.very intrinsic and highly informative.mr.carroll does a wonderful work to communicate sientific and difficult content to the public.thank you very much indeed.

This video will forever go down in infamy 🤣

"...just be inspired by it, don't lean on it in times of trouble ..." may be my favourite quote ever. But these talks are, for certain, my favourite series of physics lectures/talks ever.

I don't know about 1% but you can squeeze piezoelectric crystals to create a voltages and apply voltage to deform the piezoelectric crystals.

I am trying to get a more intuitive understanding of the quantum fields.

(1) Say that, in the normal world, we had a macroscopic object like e.g. a finger. Would there be an arrangement of vibrations in the quantum field that looks like a finger, or would the finger be represented by something like a Fourier Transform?

(2) Say that in the real world my finger pushes a small ball. What is the representation of that in the quantum field? Can I actually make something happen in the quantum field by something that I do in the real world? I would think that you need some special device (like a laser, etc, not just my finger) to manipulate a vibration in the quantum field?

You amaze me, Dr. Carroll.

Excellent !
