Physicist Explains Dimensions in 5 Levels of Difficulty | WIRED 

That first kid was like "yo what's physics" and suddenly started explaining non euclidean geometry

“You’re smarter than me” Kid: yeah

“You’re much better at this than I am” Kid : “Yeah”

As a physics student, the kid is the type of kid I always want to talk with. He doesn't know what physics means, but he has a strong intuition and good imagination which are the good starter to becoming a physician. He has talent and is hugely impressive

"why?" "Why not?" "M'kay." - A coversation between two physicists

Physicist: allow me to explain Kid: no, allow ME to explain.

I love how people are saying the first part was scripted due to the amount of knowledge the child had. Yet, the Physicist actually looked a bit perplexed at times and truly taken aback. Especially when he began to realise he needs to up his game for this level already and his prepared questions.

I love how most experts here say "That's a very good question", they are changing the student's life :)

The Kid at the beginning is like: I don’t know what physics means but here’s everything you need to know.

Loved how Rohan (the college student) kept asking further questions! It was so clear they wanted to learn as much as they could! 😄 Clifford (the expert) had an amazing charisma, and the banter between Sean and them was great! 😄

I could watch the 2 experts talk to each other for a long time

That kid was one stick short of teaching us string theory

Physicist: You’re better at explaining this than me Child: Yeah.

this kid just made me think twice about my intelligence. 💀

Each individual he explained dimensions to was just a different level of humbling to me. I fully expected to be amazed by the guest physicist. I did not expect to be impressed by every individual he was explaining to. Fantastic video, thank you all so much.

the college student saying “why tho?” is such a physicist thing to say lmao he’ll be great

This was cheating, the kid is actually the head of the physics department at Caltech

Love the banter at the end with the other physicist. Started off kinda contrary but ended as a cordial, intellectual conversation I really appreciated 🙏

The kid's reply "yes, a lot" brought a bright smile on my face. Thanks to his science teachers.

Everyone gangsta till 2 physicists start arguing about dimensions

9 year old kid : x and y axis Me 21 year old studying physics : teach me master

I love that while discussing a complicated topic as the levels progressed Sean Carroll and each respondent still managed keep the discussions understandable enough to the audience

The moment a Physicist mentions a Paper that they wrote to another "expert" the latter's reaction is immediately sceptical, at best. That's what makes the pursuit of science so productive and worthwhile.

They cheated by hiring the smartest 8-year-old they could find.

Physicist 1: “Why?” Physicist 2 “Why not?” Physicist 1: “Ok.” Theoretical physics in a nutshell

Sean Carroll is someone who can truly be classed as a 'teacher'. We are so incredibly lucky nowadays that some world-class specialists not only possess a passion for teaching - but an outstanding ability. Sean's among them. He also seems like an unbelievably nice guy - would never be condescending and is wholly without arrogance. Would love to have a beer with him.

What a great influence this guy is - both with the information he spreads and his general handling of people

Why is the first kid smarter than my entire graduating class

When the theoretical physicist and string theorist started talking I’m surprised they didn’t start levitating around the room and communicating telepathically.

I really enjoyed these kind of videos, it's very educational. Even though I didn't understand all of the things they are saying as I'm not capable of storing large information into my brain like they can and because English is not my first language, I still want to watch more. Edit: I also love that the experts in these videos, like, encourage the people they are talking with to think and asks about their opinions or their current knowledge about the topic. They don't start off with explaining stuff and don't just let others listen to them. I wish this is what they do in schools, but I get that they were able to do this because it's a one-to-one conversation and not like any classroom setups where there is only one teacher/prof and then there are 40 or more students listening and wanting to share their knowledge.

It's impressive, how he communicate with the child with only questioning and not by starting with explanations.

“If you can't explain it to a six year old, you don't understand it yourself” - Albert Einstein

Physicist: Have you ever heard the word Physic? 9yo: yeah let me introduce to you some basics of linear algebra.

Back in the days when I studied physics myself I always thought "wouldn't it be much more easy to teach 4-D if you choose 3-D space an add temperature?" Everybody (adult) understands the concept of 3D space and a temperature distribution.

This makes physics look so fun but whenever I try and learn anything related to physics I just end up sobbing

That 9 year old is smarter than he's supposed to be at that age. At that age all I remember doing was trying to turn super saiyan by shouting extremely loud

The experts: *making jokes about complex things I don’t understand* Me: *laughing*

I love listening to Sean, I don't always understand everything he talks about but he makes me feel like it's totally possible to learn to understand. That is a very inspiring quality.

22:09 “That sounds like fun.” Perhaps the most polite way to call another physicist’s idea bunk.

Scientist Talks about Dimensions Kid: I'm about to start my whole Career

Physichist: "I think you should be explaining this to me. Kid: Yeah.

He must have been so happy when the kid spoke. He exceeded his and our expectations as well.

I love this channel and discussions. Specially when explain at the different levels.

“You’re much better at this than i am “ “Yeah”

*Holds up a paper* Physicist: "Imagine we live here" Flatearthers: "Ah.. now we are getting somewhere"

These are so much fun, they should release a new season of these.

his encouraging facial expressions are just the best. it makes me WANT to learn

When an Expert talks to an Expert, it becomes a debate.

the expert level is basically watching two professionals passive-aggressively diss each other lmao edit ok I made this comment as a JOKE y'all in the comments need to chill

This is an amazing channel .it has variety of content

Trying to absorb this while doing my typical people watching… it’s curious to see how his feet spread further as he progresses through levels. It’s fine of course, most of us prefer to speak on our level. What I love it that many of we more intellectual sorts have awful social skills, and it was delightful to see good interactions with the young.

They should make it 6 levels: Flat Earther, Child, Teen, College Student, Graduate, and Expert.

Physicist talks about coordinates: “do you know what coordinates are?” Kids who play Minecraft: my time has come

This is great. Its so fascinating to see the this tiered system of knowledge that becomes more advanced until it is at the cutting edge of current research.

I hope that kid does okay and has good parents. He could look back on this with pride just the same as he could look back and be ashamed some day. It's grim and no one want's to think about it, but no one knows where anyone will end up. He's a smart kid and I hope he gets fed good cards out of the deck of life.

The kid caught me off guard, the kid really understood dimensions He’s the real expert

Kid finishes his segment, lights a cigarette: “This is so degrading. Mail me my check, would ya? I gotta get back to my camp gig.”

I would listen to these two experts discuss this for days.

"I think you should be in this chair and you should be explaining this to me." "Yeah." That is my favorite part

Two experts: *start talking* Brain: You can stay, but I'm leavin'

"I think you should be in this chair teaching me" *"yeah"*

One of my favorite 5 Levels discussions....Dr. Carroll was a fantastic explainer and I'd like him to explain everything to me :)

This is so interesting to watch! i love speculating on things like this

Y’all cheated with the kid, he’s far more aware of science and technology than the average child lol

Physicist: So, do you know what a dimension is? Kid: I’m about to end this mans career

These are great, I feel like physics is the one subject that just completely evades me. Probably somewhat of a self-fulfilling prophecy, but everything seems to be opposite of “common sense,” and even if I start to understand something, the understanding seems to slip away in a minute. Videos like this make me want to keep trying though, because I feel like understanding all this would be incredibly mind-blowing.

I enjoyed this. Thank you for sharing. I would like to get both of their books.

"Why?" "Why not?" "M'kay" This is physics in it's entirety

Watching the physicist explaining to the expert looks like a battle between the gods

I’m a CNC machinist, which isn’t the most learned of careers, but I’ve been genuinely surprised by how much my training has been useful in contemplating the reality of higher and lower dimensions.

The simple fact this kid can answer these questions better than all of my classmates and even me can is impressive. Like little man big words

I'm confused, why did they bring out the expert first?

“You should be explaining this to me, you’re much better at it” “Yeah”

I was able to wrap my head around everything easily when the expert came out. And after that i just couldn't follow the conversation even. I'm happy that i knew 90% of what the grad student said being a high schooler myself hehe

They always have the sweetest people in these vídeos! I love it

Kid: 3D is the maximum dimensions Physicist: I'm about to end this kid's whole career

LMFAO THAT KID "you should be in this chair, you're much better than I am" "yeah" F

I am a student going to college next year, but I think I got it. It was really interesting. Would you please do these things again?

It takes a highly intelligent person to discuss and explain a topic or subject in five different levels of, understanding of complexity and difficulty. I enjoy watching these videos with these leading experts in these fields of knowledge, it’s very interesting to see how they deconstruct a topic they are so passionate about.

*fastforwards to expert level*. -“Why?” -“why not?”

Sean is fantastic at demystifying tough concepts. I'm surprised the concept of "independence" never crept into any of the narratives (ie a third vector pointing northeast would be redundant given the existence of a north and east vector in a 2D space to identify a point ). If a physical space is evolving in space time it's interesting to ask what other independent dimensions would be useful to encapsulate / annotate it. A positive or negative value for entropy maybe.

3:20 Took me until I was 13 or 14 to get x and y axis. It's incredible that this little fellow knows this already! Cudos!

Me watching the video: "Hey this is pretty interesting although I don't really understand it all." Me talking to friends afterwards: "You fools, you absolute simpletons! Can your feeble brains not count higher than three?"

"Let's imagine this is our entire world (referring to a sheet of paper)" **flat earthers go wild**

Amazing idea, planning, execution and video. Thanks for that.

In regard to the first convo; I love a sweet, smart man! I love a lil sweetie even more! This just melts my heart and tickles my brain. Love it!

The kid: yeah The teen: ohhh The college guy: hmm Brad student: how Expert: why

Why did the Expert level seem like they were having a freestyle rap battle but with Physics

A. D. Miles did such a good job in this role. Shows what method acting does!

Something to listen to as background noise as I drive. Only now I have hours of research on branes and black branes in my near future.... thx again Sean Carrol.....

this child is a genius no offense but he’s describing dimensions better than i could

I love how great minds debate - Why? - Why not? - Agreed.

I am completely blown away. It is the the first time I watched a a video about dimensions and understood what those dimensions are and I watched many of them. Now I understand Twin Paradox and it is not a paradox in fact. I don't need to remember some parts that I "knew the definition" but didn't really understand and now I can just solve the paradox in my head. This feels like I just unlocked some doors in my head.

The kid at the beginning is really smart for his age. I was surprised and hope he has a long future in the sciences.

I remember being offended when I found out there was math in science.

No joke, this kid is smarter than most adults I come in contact with.

Watching him with the kid reminds me of Mr. Wizard. I loved that show!

The way clear explanation of a topic or subject can fuel one’s curiosity and interest is mind boggling.

They should make a show where they explain science to drunk people

First kid starts talking Harvard Students: take notes
