Of all the people featured here, Sean Carroll is one of the best at communicating clearly and precisely.

Brady, I love what you have done for us here with all these channels. I don't think I've ever learned as much as when you interview these brilliant people. And your way of asking questions just shows what a great view of life you have and how you really burn for these types of questions. These channels are my go-to place whenever I need a thoughtnugget, thank you so much for doing this for us!

Please tell Sean that he needs to narrate a documentary at some point in his life. He is so good at explaining things and I could easily listen to his voice all day!

The fluency and clearness in they way he talks is perfect.It makes those who don't have a physics background help get a grasps on these fundamental ideas. As can be said about all the other talkers on sixtysymbols, and Brady's other channels. Bravo.

Brady, you do a really great job editing these videos. Enjoyable to watch.

I could listen to Mr. Carroll talk for hours. His mannerisms, speech patterns and inflections make him very interesting to listen to, while his explanations are well articulated for folks who haven't a clue what he's on about going in. He makes complex subjects easy to listen too, and hopefully learn a little from.

mentions breaking an egg and scrambling it dumps whole egg in a bowl and tries to beat it

"goes up and and down".. funny face realizing that his hand went in the other order.. "I should say down and up" LOL

I like this guy. He explains things very well and is enjoyable to listen to. Please include him in more videos.

Really enjoy the videos you've made with this guy Brady. He explains things very clearly and in a lot of depth and his analogies are so insightful.

He reminds me of James Woods. Wish I had a physics professor like him at university...

What makes these videos damn awesome is the fact that Brady always asks the questions the rest of us are thinking about. That's why I love these videos and think that these are more educational than many straight up explanation or teaching videos of the same topics.

By the way, thanks for being probably the most insightful and broad-ranging youtuber there is :) Keep up the awesome stuff, you inspire alot of people to take up particle physics, mathematics, etc. through your videos.

"Retrodicting"! A wonderful word that I hadn't come across before. Thanks for that.

It means that your brain is attempting to move backwards in time by organizing information, while the universe is moving forwards in time by disorganizing that which began in an organized state. We are trying to remember what the universe has forgot.

Really nice question!. However, as time is basically interaction, if nothing occurs before the big bang then there is no change in space. If there is no change in space, then as spacetime is inextricably linked, there will be no change in time, and thus no direction to it.

There are some interesting discussions about that topic

I thought he was talking about One Direction

I really love this guy. To me he has a incredibly good interpretation of "things".

I gotta look that up in that case! In the few videos he has been in on sixty symbols he's starting to become one of my favorite "stars". The way he explains things is extremely clear and always spot on. Enough detail to keep it relevant and correct, but simplified enough so us normal people can understand it in one go. Quite honestly I'm baffled after every video with him in it. Such a smart and inspiring man to listen to.

Has he ever thought that maybe it could be a big ball of wibbly wobbly timey wimey stuff?

Except it isn't. You can measure time, it can be defined by other physical quantities, and you can measure its effects on objects. It is antithetical to metaphysics.

Stop with your nonsense word plays, there are no measurements within metaphysics, there is with time; there's a huge distinction between the two. So yes, I suggest you stop repeating idiocy without conscious consideration of what you're saying.

I don't believe in an 'arrow of time'. I believe that time is just like space, it has no natural direction in which it progresses. The arrow of time I think is an illusion created by the fact that we remember our past and not our future. This gives us the illusion that we are progressing in time and essentially moving from our birth to our death at a fixed rate. This rate would be the speed at which our brains process information and turn the information into short-term memories. I believe that all our versions are existing and real, just as real as a third spacial dimension is compared to the second. Only those versions have different memories which makes each version think it is progressing in time. This is a really interesting way of looking at the difference between the world the way perceive it and the world the way it actually is, with 4 dimensions rather than 3 dimension of space and 1 progressive time dimension.

I'm another 3+1 dissenter who believes time isn't unique amongst the dimensions. I'm not with you on the many-worlds interpretation, but I'll help you make your case for 4 dimensional space... Let's start without a reference frame. It is impossible to say how fast objectX is going, the rate of its clock, how compressed it is in any of the spatial dimensions, or its mass. But, objectX has itself as a reference frame. We can now say objectX has no movement in space, its clock runs at full speed, it's uncompressed in all dimensions, and has mass of X. Pick any other reference frame, and things start to change... The subset of possible reference frames that see objectX as moving arbitrarily close to c is still infinite in number. The universal constant is a ratio of space to time, but thinking of it as a speed gets the numbers right, but misses the point. It's a ratio of equivalence. One second=186000 miles

I love Sean Carroll and I love Sixty Symbols! How did I miss this one.

Congratulation to Brady and Dr. Sean Carroll for the great video! It was such a good conversation! Thank you very much

Sean Carroll videos are always good :) more of that !

As about 12 people have mentioned before me, Sean's voice is great. The topic/discussion was great too, but there are lots of those on this channel. Sean's voice stands out notably.

He's got a good voice and style for this kind of thing. Very clear and engaging.

Stunning line of arguments.

This guy is excellent with... everything relating to what this channel tries to achieve.

So many Brady Haran videos released in one day. Today is a good day! :-)

I've heard this explained before, but not quite as well. Thanks Brady and Sean!

Thanks for the educative explanations for such difficult questions!

Amazing video, thanks for making this information available.

"air molecules" apart, i get really excited when i watch this kind of video! Its awesome beacuse It not only teaches us how the universe works, but give us something to thing about. But, if you allow me, Brady, for most of the topics covered in your videos, 10 minutes is not enough. As Derek, from Veritasium2, said in his last video: "...there are things that get better just by lasting longer."

I really liked this episode. This is the kind of thing I like to learn or hear about.

Great video! The most awesome is the idea of comparing time and space - "space has `arrows` when near a big body" and "time has `arrows` when near a big event"

Awesome video ! Sean Carroll is a great explainer

I really dig Dr. Carroll! I could listen to him talk about physics for hours (and have thanks to a number of talks available on KZread!). Make sure Brady you corner him every chance you can get! And keep up the excellent work. I would like to see more 60 symbols videos (as much as I like Numberphile I love me some physics...)

This channel is regularly blowing my mind. Thinking of time as a similar function of gravity just turned my views upside down.

No problem. The point to take home is that, other than our own memories, entropy defines events that have occurred earlier with events that have occurred later. If you look at two different photos of the same event, the one with higher entropy can safely be assumed to have taken place later in time, such as a glass of water occurring later than a glass of ice, a slower pendulum occurring later than a faster pendulum, etc.

In the video "Relativity Paradox" on this account, simultaneous events can occur at different times. If the trainspotter was on the end closest to the entrance then the train would first see the guillotine come down, and then see them press the button after the train was through. By changing your momentum you can alter time in the area around you as well, until you stop accelerating and move at a constant speed.

I like the way he talks - very clear and concise.

I agree, man. Awesome job! Love this channel. Keep up the good work.

Just love these types of vids!

By the way, I think you explained this topic marvelously. Congratulations!

just realized this is the guy that does some of the best pieces of work for the great courses. if you have audible its a must buy

Finally! I was waiting for this since january.

This guy is great. keep up the good work as always

Very good questions Brady. Awesome video!

I enjoy his voice and how he formulates what he says.

Very Interesting video, as usual from sixtysymbols, thank you! It did however somewhat strike me as odd to say that Aristoteles didn't give time much thought, when in fact his fourth book has four chapters devoted to time. Sure they were not the last words on the subject, but there were some serious philosophical fundamentals laid there.

Finally! I was afraid you had given up on sixtysymbols. Thanks, Brady, once more you saved Townsville.

this channel is heaven. thanks.

New Computerphile, Numberphile, and Sixty Symbols videos within a week. I think my head just exploded!

Truly excellent explanation. This man is a fantastic teacher.

Thank you a lot for these videos .

I've heard an explanation for the arrow of time that goes something like this: You can only observe increasing entropy because increasing entropy is the only way to disseminate energy that can be observed. It may be that time goes in both directions simultaneously, but we are unable to observe the reverse evolution of the universe. If you were to reverse the scrambling egg, you'd have to reverse the molecules that formed the memory of the egg ever being scrambled in the first place.

He's a great speaker. Who knew you could take such a wibbly-wobbly concept of the arrow of time and make it sound so logical?

I laughed @ 3:17 It sounded like he is saying "arse water"

I quite enjoy these videos with Dr. Carroll, do you have plans for any others?

Well done Brady :) I liked this one!

Love this guy's voice. I could just listen to him talk physics all day.

I was just watching a Bryan Cox lecture on this :)

This was really interesting, thanks!

his voice is very pleasing, it is easy listening to him

Time can move in any direction. It's not a question of "which way it's going," but rather where the system is going, what direction force is being applied, where heat is being released, so on. He did say what direction it's going in - toward entropy. And I believe it was an analogy, the astronaut - and a 'relatively' good one.

I could listen to these guys ALL F**KING DAY and still not get bored haha thanks Brady keep me coming! I need to stay sane haha

I said his way of asking questions, not that he asks questions. How does being duped even come into it. He's always interviewing an expert in the field being discussed who is considerably more intelligent than himself, and the viewers for that matter. I'm glad he asks questions and the content of the questions is bang on, but I think they should be asked with a lot more politeness and respect. These people being interviewed are giving up their time for free to help him make videos.

Sean Caroll is awesome, his General Relativity book is great.

A proton travelling backwards in time would still have a positive charge, it's +1 charge comes from the sum of charges of the two up quarks and a down quark that make up the proton, the fact that it's travelling backwards through time doesn't necessarily convert the quarks to anti-quarks. Just my guess, but you might want to check that up, it's a good question :D

Sean Carroll might seem a little bit like a know-it-all, with no intention of offence on my part, but he speaks with such a pedagogical voice, and with such clarity, that I can type this comment, watch the video at the same time and still understand everything that has yet been said in the video. I'll keep watching now.

Get this man his own TV show. Superb presentation.

great video as always :)

Objectively, I don't think Professor Sean Carroll is any better (,or worse than the others of the professors, although all are GREAT,) than the other professors here at sixtysymbols, but I feel that somehow, his slightly deeper voice and casual way of talking conveys a greater meaning of facts. Again, I'm not questioning the skill, nor knowledge, of other professors, but... aww man, I just enjoy hearing him talk. Unless you have a factual objection, please don't correct me. Have a nice day. :)

I wait in anticipation of these videos! Awesome stuff. Does anyone know what "Sixty Symbols" referances?

Professor - look into the discussion of time in St. Augustine's Confessions books ten and eleven. I don't remember whether he considers the arrow of time but he has some surprisingly modern-sounding ideas about time and human memory - back in the 400s AD.

When Brady mentioned time as a river, all I could think was the opening to Prince of Persia: Sands of Time. "Most people think that time is like a river, that flows swift and sure in one direction. But I have seen the face of time, and I can tell you: they are wrong."

I recently read his book "From Eternity to Here". It's really, really interesting, and if you have any sort of questions about this stuff it's the one book you need to read.

I love how Sean Carroll always has this face like he's trying restrain laughter due to the fact that the explanation he's inevitably about to give is going to be about something comically abstruse and bizarre. 0:01 is one such example.

This was an eye opener!
