Ed embodies the humble, softly spoken, yet fiercely intellectual scientist, using his imagination to delve into the mystery of how the universe came to be. Putting out those Aristotelian 2.0 vibes.
Hi all - have seen comments for an against the text… I decided to write a little blog about it for those interested in the editing process… Link in the description.
Sixty Symbols I know I'm late on this reply, but my opinion on the the text is it would be perfect without the black background. Just the white text in a transparent layer on top of the video, perhaps smaller and to the side so it doesn't block the subjects face too much. As always thanks for your hard work on the videos!
I can imagine this man as actor playing serial killer talking about all his journey in jail ;) But seriously its pleasure to watch him explaining anything
love the longer format. perhaps there can be a balance struck between the short and long scale videos on this channel. also loved hearing him talk about exactly what he wanted to with minimal interruption, got to see a small window into how the professor's mental gears work. interesting how he said more than once that he continues and persists with this idea because of its "beauty". in a way i suppose artists and scientists aren't so different, they both deal in the constant struggle to convey truths. beauty seems to perhaps be a happy aftereffect. keep 'em coming Brady :)
I agree! And a lot of times the beauty is in the truth itself, as well as the approaches to discovering the truth, interpreting it, and even in simply the process itself. There's beauty as well in how the information is conveyed, represented, taught, talked about, joked about. Science is fundamentally a creative and artistic process, and just like art, science can be easily appreciated by most people if it's packaged the right way. However, just like art, there are also many things that are totally unapproachable except for the initiated. Can a layperson experience the feeling of playing a difficult piece on the guitar? That type of appreciation requires a specific technical ability. Science of course has many facets that are similarly difficult to appreciate.
ed's description at the end about how he would feel if strings didnt exist is just so amazing - we need more people like this. taking chances etc giving things a try. and if everyone took chances, not everyone would be right but its not about individual achievement its about humanity's achievement as a whole. so glad there are people who havent given up on string theory!
Ed is such an amazing person. I like his competence, his voice, that he is always smiling in enthusiasm and humility, how he can explain stuff, and that he blushes sometimes (note the red ears towards the end of the video). Such a brilliant and likeable person.
I play videos with Proffesor Ed on my phone as I sleep. His voice is like a warm blanket snuggling me to sleep. Plus, I swear I wake up each morning just a little bit smarter.
Oh Please - more like this! Seriously - far more interesting to hear about the more advanced concepts - most of us are geeks and nerds, so we can follow. Loved the in depth explanation, I definitely see why all the enthusiasm to detect the defects now.
I love whenever professor Copeland talks about what he's passionate or excited about, he gets a huge grin on his face, even if I don't fully comprehend what it is.
The way Ed talks is extremely soothing and really makes you understand what he's saying or explaining. Some scientists/physicists speak in a rather smug or over confident way that is almost disengaging when they are trying to explain a point. Ed is the complete opposite and I could sit and listen to him explain anything for hours.
Ed seems like an amiable, charming fellow, happey for him winning the prize. Evan if no full comprehension of the advanced physics theories he speaks of, still enjoy the videos he is in.
Love the explanation but the text was distracting. I wouldn't mind if they were animations supporting what the professor was explaining though. In fact animations would supplement the video.
I really enjoyed this format. It's just such a Joy listening to Prof. Copeland. It would be great if there were more videos like this, with the other professors as well.
Ed Copeland is simply amazing. I can listen to him for hours... Great, great video again Brady!! I really appreciate your work and the professors willingness to talk about these subjects in a way that we can grasp the general idea. This is priceless for humanity!
There should be a Professor Copeland radio station and website. I could listen to him forever, morning, noon and night. Thank you for the in depth video. I am grateful for your time. I do not understand cosmic superstrings but what I do understand is your dedication, focus and hard work that defines physics to me.
5:00 ... so the object has to move to emit gravitational waves? Was just the presence of mass enough to bend space-time? Or are those gravitational waves something different completely?
Nice and smooth explanation Prof. Ed. Mesmerized by your voice and again..again I just want to listen your speech. and thanks to Bro Brady posted this video. from Malaysia.
some quality material right there ! things are called with their names and the fact that there are doubts about them and passion about them gives me hope that we eventually figure this out ! It is nice to see scientists like professor Copeland walking us through cosmology and terms ! Just by watching this video one must gain some intelligence , getting to know what is out there is at the very least incredible and interesting !
I went to Nottingham (Russian Studies.... Oh dear), and I'm now very proud. Numberphile, Computerphile, and Sixty Symbols are all great educational tools for 'interested people' (in the spirit of my favourite place, the British Museum). Well done, and congratulations from one of many alumni. Nice!
I love professor Ed Copeland ...this is the best video explaining cosmic strings out there! and it is a mesmerizing watch worth watching a time or two extra, then revisited later.
Could these cusps (not sure about how to write this..) I mean the ones that beam out gravitational waves be responsible for fast radio bursts, or are these not capable of loosing energy in the electromagnetic spectrum ?
Hi Brady! I would just like you to know I loved the text questions and here is why: Sometimes, or quite often, it seems like your own volume is somewhat lower than the people you are interviewing. This sometimes makes it difficult to hear exactly what the question was. With text there can be little doubt. Also it's always nice to have a more or less uninterrupted torrent of science from Prof. Copeland.
dear brady, as an aspiring theoretical phys student. i so so so much wish that you can have the chance to interview ed witten!!!!! thanks for this video. its greattttt
After watching this numerous times followed by me crying myself to sleep over my brain's inability to fully understand this concept, I think that I'll be quite ready for one of the next parts now :) Congratulations on winning the medal. :)
A half hour Sixty Symbols video... Christmas has come early!

Also, I just had to pause to say this, please, don't put on-screen text that completely blocks the speaker. It's just plain distracting. If you really think you have to put write on the screen every other sentence he says, please do so as some form of subtitle.
Since so many people don't like it I don't think there should be anything. The point of the text was to place emphasis on things he said. Sublte subtitles wouldn't achieve this effect and just end up being useless and tacky, and possibly even more distracting than the original text. So yeh just get rid of it imo :)
Not reading through 456 comments so would not be surprised if this is not already flogged to death as a possibility..but.. given that the css's formed very early in an initial expansion event and that deep sky observation says SMBH's did too could they not be one and the same? Not whole strings perhaps but fragments of them. A collision of strings might cause such a gravitational well that drags in both or multiple pieces and/or lengths of strings resulting in the massive singularities we see. Strings with energy transferred to rotation would have their angular momentum maintained, at least to some measurable extent, and explain the uniformity (sigma) of rotation in spiral galaxies. Others, due to direction and impact velocity, would be cancelled out and form giant non-rotational elliptical galaxies. In the kinked string analogy used - if the kink always ended up on an inward facing direction, toward gravitational center it would remain very weak and hard to detect. And the structure of the cosmic web itself surely looks like a string vest! Whatever the truth a fascinating and inspirational video from a guy truly great at explaining "stuff".
My respect to the Prof. It takes all my knowledge to keep up with him, and these theories I have never heard of. I am SO looking forward to the other 2 videos. Please more LONG videos (like this one)!!
I'm not going to pretend that this makes any sense to me... From my relatively primitive physics classes I've realized that it's impossible to visualize most of this stuff so i just trust the math. Math always delivers. Mostly.
Does the new data from BICEP2 (I'm watching this video a bit after you uploaded it) have any bearing on the search for cosmic superstings? I'm not a phyicist, but I noticed that Professor Copeland mentions at 18:37 that cosmic strings could create B-Mode polarizations, which BICEP2 has just found.
+bruinflight The recent observation of gravitational waves is probably the most relevant breakthrough since this video was made. We will probably see some news about strings and other "hypothetical" bodies in the next few years from gravitational evidence.
15:40 'You're just making this stuff up aren't you?' So brilliant, and the way Ed just ignores it is as brilliant. Reminds me of some guy named Ockham who just made up a razor out of thin air. But he never proved that it existed.
Congratulation on getting the medal. Fantastic video I really appreciate the time and effort that has put in making this. I personally think that the result will end up being negative. However I love the work you are doing and I really do hope I am proven wrong.
I love scientists who work on less popular, riskier investments. Even if they don't pan out, we get to now know that, thanks to them. Not to mention all the other research and discovery generated by the pursuits. Someone has to do that work, and science as a whole benefits from it. We owe a lot to them.
Wow superstrings - apparently really interesting objects! Congratulations to Professor Ed Copeland on the medal. It is always a pleasure listen Prof. Copeland at Sixty Symbols!
Just wanted to make a comment about a thing mentioned by Prof. Copeland. It is true that the analogues of cosmic strings do exist in many Condensed Matter Systems (also including other types of topological defects, besides line-like ones). Actually these exist in systems most people have already seen! For example they exist in superconductors, where they are called "Abrikosov Strings" (Nobel Prize 2003). The so-called Meissner effect is the reason a superconductor levitates in the air, but it's these "cosmic string" like objects inside the superconductor that makes the levitation "stable". So without these strings in a superconductor, the amazing levitation demostrations would not have worked properly!
I've gotten to the point where there's too much good TH-cam to watch -- and then I stumble on a video like this. Providing such a long, deep dive for the layman is incredible, Brady and Ed. I think this is some of your best work that I've seen.
one of the reasons i was never friends with physics in school was because of the ammount of "equation memorizing" that it involved... but since i started university (computer engineering) ive been reading up on modern physics without the pressure to "memorize or fail" ive been finding it so mezmerizing and interesting... I could probably watch videos like these for hours on end
thats one thing i find weird: some teachers make you memorize all the equations how i was taught was, you have a very small set of information and you just derive the equations. in gr. 11 we werent given an equation sheet cause you can just reason out all the simple equations (12 and 1st year were a bit harder... i still did it though cause it made my life easier) i literally went through high school up to most of first year without memorizing any equations but now i kind of have to because deriving them again during an exam takes too long, but its still easier to memorize things you understand fundamentally.
I would like to know the meaning of all the equations shown in this video (like at 9:08). Information about this kind of stuff is really, really hard to find.
Love your channel and Professor Copeland's videos. Just started checking them out and am fascinated. Not a science person but these videos help me to understand. Thank you!
I would love to sit & talk with him about these subjects. He explains it so I can grasp the ideas. I can't do the maths but the ideas are understandable.
at 25:00, when he is talking about the matter getting 'sucked in' behind the string, I thought of a decent example how how to visualize it: think of stirring brownie batter with spoon, and imagine what that looks like in that batter when you move the spoon quickly in a line.... that's what it looks like.... pretty much.
The difference lies in the fact that in physics we might believe in things and get excited and maybe even obsessed, but the ultimate goal is to PROVE that something is true.
I've seen some comments saying that STring Theory is worthless - you should probably do some research. It's produced valuable work - regardless of whether it turns out to be our final theory or not - and it's not the most popular pursuit of theoretical phsyicists for no reason.
The professor +Ed Copeland has said that among those cosmic superstring those that are self-intersecting are the more common, but also they decay very rapidly. This may mean that those has dissapeared early on. On the other hand he did mention that the structure of galaxy clusters seems to resemble that of cosmic superstrings that don't self-intersect. And also that the primary way for those strings to lose energy is by gravitational waves. That may mean that those strings has been able to live long enough to rearrange matter but they have lost their energy in the process and that's why we can't find them. All in all, it seems to me that those cosmic superstring may has very well existed. But if they did, they no longer do. Just like the example of what will people think of stars in a universe in the theorical situation where the (ever accelerating) expansion have reached a point where all the stars are too far appart to see them. In that situation, people will probably say that stars have every right to be there, that the process in which they think of them forming makes complete sense, but still they don't see any evidence of them being there.
I love how Professor Ed Copeland explain things.He is calm and radiates positive energy.
and gravitational waves

'FLOP AROUND'
THANK YOU SOOOO MUCH FOR THESE VIDEOS. I HAVWE LEARNED MORE ABOUT SCIENCE/PHYSICS AND OUR UNIVERSE FROM THESE VIDS THAN IN 16 SOME YRS IN SCHOOL
@Nonprophet, that wouldn't help point 2 very much. I prefer the black background
would it be possible that cosmic strings are flows of neutrinos or something
I get so excited when science videos are tens of minutes long. More of these the merrier :o.
I love the idea that Ed Copeland sometimes gets quite angry.
Would’ve looked odd to me
I can imagine this man as actor playing serial killer talking about all his journey in jail ;) But seriously its pleasure to watch him explaining anything
I get the impression that if you were to genuinely disrespect him, he would destroy you.
Hes a passionate man
Professor Ed is my favourite by far!
love the longer format. perhaps there can be a balance struck between the short and long scale videos on this channel.
also loved hearing him talk about exactly what he wanted to with minimal interruption, got to see a small window into how the professor's mental gears work.
interesting how he said more than once that he continues and persists with this idea because of its "beauty". in a way i suppose artists and scientists aren't so different, they both deal in the constant struggle to convey truths. beauty seems to perhaps be a happy aftereffect.
keep 'em coming Brady :)
I agree! And a lot of times the beauty is in the truth itself, as well as the approaches to discovering the truth, interpreting it, and even in simply the process itself.

Speaking of beauty, have you heard of Perfect Fourths tuning? You may find it interesting.

University of Nottingham must be a great place to work! Every single person there seems so pleasant, genuine and knowledgeable.
I know it is not for everyone, but I love the longer videos that allow Dr. Copeland to go into slightly more detail on the subject. Keep them coming!
Congratulations on the medal as well!
I play videos with Proffesor Ed on my phone as I sleep. His voice is like a warm blanket snuggling me to sleep. Plus, I swear I wake up each morning just a little bit smarter.
I do the exact same thing
@@RedXFitness there's dozens of us!
Prof. Copeland is such a joy to listen to. All of his videos exude a passion for physics that is genuinely contagious.
Oh Please - more like this! Seriously - far more interesting to hear about the more advanced concepts - most of us are geeks and nerds, so we can follow. Loved the in depth explanation, I definitely see why all the enthusiasm to detect the defects now.

No matter what the results are, the observations made while trying to understand this can be important for other theories.
Ed seems like an amiable, charming fellow, happey for him winning the prize. Evan if no full comprehension of the advanced physics theories he speaks of, still enjoy the videos he is in.
What he explains seems so out of reality to me that it almost feels like I'm watching a drug addict going into a mad hysteria or something.. xD
Loving the HD and the text format!
I had to pause Brady just to say, this video's on screen text is fantastic. You are the best!
Would love a follow up on these videos with Ed!
Professor Copeland is my favorite. He just has a knack of describing things and making them sound interesting. Congrats on the medal!
Love the explanation but the text was distracting. I wouldn't mind if they were animations supporting what the professor was explaining though. In fact animations would supplement the video.
So, what happens if a string passes the event horizon of a black hole? Is it like a kid eating spaghetti?
Well it will be much faster maybe :)
The string tension will probably break it.
I do know one interpretation suggests a time machine would be formed.
@Xavier: Which seems like further evidence that such strings don't exist.
Yes but the spaghetti becomes spaghettified.
I really enjoyed this format. It's just such a Joy listening to Prof. Copeland. It would be great if there were more videos like this, with the other professors as well.
Ed Copeland is simply amazing. I can listen to him for hours... Great, great video again Brady!!

+Kavetrol pressence of mass is enough to bend it, movement (and quite specific movement) is enough for waves
what is the man holding in the selfie at 0:14 seconds. Serious question . very intrigued, please respond
The great thing about you guys is-you show the the original papers which helped me cite them in my work.
Nice and smooth explanation Prof. Ed. Mesmerized by your voice and again..again I just want to listen your speech.

I could spend hours listening to Ed talk
You should do more of those, I like the format. 30 mins is just about right.
Really good to hear Dr Copeland go into some detail. I would love to see more of these deeper expositions on Sixty Symbols
Most of science is failure, but it's on those failures that success is built.

Congratulations on winning the medal. :)
Awesome video. Though I do think the abundance of random full screen quotes is a bit unnecessary.
Yes. Annoying full screen quotes are annoying…
_We apologise for the full screen quotes. Those responsible have been sacked._
I don't know, they help keep me focused. I'd actually prefer more illustrations.
I agree with Dennis. They're not random, they're emphasising specific phrases, and occur simultaneously.
I second (or whatever count it's up to) the opinion that the full screen quotes are unnecessary.
see link in the video description
Sir I only wish I could reach even 1% of your accolade! You totally rock! Congratulations!!
A half hour Sixty Symbols video... Christmas has come early!
Also, I just had to pause to say this, please, don't put on-screen text that completely blocks the speaker. It's just plain distracting. If you really think you have to put write on the screen every other sentence he says, please do so as some form of subtitle.
I completeley dissagree, I actually really liked it.
Da Lucanator Would subtitle styled text be an agreeable middle ground?
Since so many people don't like it I don't think there should be anything. The point of the text was to place emphasis on things he said. Sublte subtitles wouldn't achieve this effect and just end up being useless and tacky, and possibly even more distracting than the original text. So yeh just get rid of it imo :)
Fantastic clarity of thought and expression!
he needs to be in a podcast, his talks are mesmerising
Not reading through 456 comments so would not be surprised if this is not already flogged to death as a possibility..but..
given that the css's formed very early in an initial expansion event and that deep sky observation says SMBH's did too could they not be one and the same? Not whole strings perhaps but fragments of them. A collision of strings might cause such a gravitational well that drags in both or multiple pieces and/or lengths of strings resulting in the massive singularities we see. Strings with energy transferred to rotation would have their angular momentum maintained, at least to some measurable extent, and explain the uniformity (sigma) of rotation in spiral galaxies. Others, due to direction and impact velocity, would be cancelled out and form giant non-rotational elliptical galaxies.

This one's going to take a couple of views to really sink in.
Congrats to Dr. Copeland for that medal!
My respect to the Prof.
It takes all my knowledge to keep up with him, and these theories I have never heard of. I am SO looking forward to the other 2 videos.
Please more LONG videos (like this one)!!
One of the best sixty symbols videos so far and it reminds me of Stephen Baxter's novel "Ring"
2ot
Brady: love your work and listening to Dr. Copeland. These cut-aways to the block letters on a black screen are, however a little jarring.
Is it possible that the FRB's we've discovered, could be coming from the string loop the prof talked about? around 16:00
I'm not going to pretend that this makes any sense to me...
From my relatively primitive physics classes I've realized that it's impossible to visualize most of this stuff so i just trust the math.
Math always delivers. Mostly.
You can't trust math alone. If the math is correct but the experiments are inconsistent with reality, then something is wrong.
At 4:57, "the strings radiate gravitational waves". If so, with the enormous mass of these strings, shouldn't LIGO detect them?
At 28:07, Professor Copeland talks about his 'first work', I can't catch the name since he says it so fast. Can anyone tell me what he said?
I observed a face transition from :| to :D when you got the medal. Congrats!
Does the new data from BICEP2 (I'm watching this video a bit after you uploaded it) have any bearing on the search for cosmic superstings? I'm not a phyicist, but I noticed that Professor Copeland mentions at 18:37 that cosmic strings could create B-Mode polarizations, which BICEP2 has just found.
Is there any follow on? This is nearly 2 years old at this point...
+bruinflight The recent observation of gravitational waves is probably the most relevant breakthrough since this video was made. We will probably see some news about strings and other "hypothetical" bodies in the next few years from gravitational evidence.

Brady, Ed.. keep doin' whatcha doin'... you guys produce amazing works.
Imagine my surprise and delight at seeing such a nice long video after reasonably long break :) Thankyou sixty symbols.
Congratulation on getting the medal. Fantastic video I really appreciate the time and effort that has put in making this. I personally think that the result will end up being negative. However I love the work you are doing and I really do hope I am proven wrong.
The text should pop up at the side so that I can still see the prof.

Super stoked for the Professor!!! Congratulations to him for the award. I love these long ideas!!!
When are we gonna get an unpdate on this? LIGO is working now, so maybe there's a new development?
If they had found them by now, we'd know about it.
Wow superstrings - apparently really interesting objects! Congratulations to Professor Ed Copeland on the medal. It is always a pleasure listen Prof. Copeland at Sixty Symbols!
the choice in which phrases are put into text inside the video is proof that natural scientists will always make the best comic writers
This interview was great. I look forward to the next two.
Just wanted to make a comment about a thing mentioned by Prof. Copeland. It is true that the analogues of cosmic strings do exist in many Condensed Matter Systems (also including other types of topological defects, besides line-like ones).

What a fantastic video, this is the kind of physics that really gets me all fired up, wow !
Channels like these are really great. Very grateful to be a subscriber. :)
I've watched this multiple times and Im still having trouble comprehending this :/
I would love to sit & talk with him about these subjects. He explains it so I can grasp the ideas. I can't do the maths but the ideas are understandable.
at 25:00, when he is talking about the matter getting 'sucked in' behind the string, I thought of a decent example how how to visualize it:

FLOP AROUND! best battle cry, ever. Love the captions. Congrats Professor Copeland.
I'd like to see a video juxtaposing him expounding on the nobility of this theory versus the politics of getting awards in science
I've seen some comments saying that STring Theory is worthless - you should probably do some research. It's produced valuable work - regardless of whether it turns out to be our final theory or not - and it's not the most popular pursuit of theoretical phsyicists for no reason.
The professor +Ed Copeland has said that among those cosmic superstring those that are self-intersecting are the more common, but also they decay very rapidly. This may mean that those has dissapeared early on.
On the other hand he did mention that the structure of galaxy clusters seems to resemble that of cosmic superstrings that don't self-intersect. And also that the primary way for those strings to lose energy is by gravitational waves. That may mean that those strings has been able to live long enough to rearrange matter but they have lost their energy in the process and that's why we can't find them.
All in all, it seems to me that those cosmic superstring may has very well existed. But if they did, they no longer do.
Just like the example of what will people think of stars in a universe in the theorical situation where the (ever accelerating) expansion have reached a point where all the stars are too far appart to see them. In that situation, people will probably say that stars have every right to be there, that the process in which they think of them forming makes complete sense, but still they don't see any evidence of them being there.
And I just gotta say to Ed, it is awesome you taking up for Tom Kibble! ESPECIALLY since Tom came up with the Higgs mechanism.
that 'stash though brady...
I would love to see some animations of strings to go along with this talk.
Or it would be great if actually had a string or shoelace in his hand.
"Does exactly what is said on the tin" Never heard that one before, yet its meaning is immediately obvious. Now I'm totally gonna use that phrase!
15:00 once a cycle as in a CPU cycle!? The universe is a simulation! Half life 3 confirned!
