Sixty Symbols videos by Brady Haran
This is mind-bendingly interesting. This device represents the pinnacle of human scientific development, not just in the field of physics, but in our fundamental understanding of the very fabric of the universe.
I just wish I understood it.
Love his enthusiasm!
+coldsoup49 The result of loving what you do for a living. We all should pursue our passions, it's the secret to a happy life.
So, I'm new here, but I think this has officially become my favourite channel on RUclips.
That mans enthusiasm restores my faith in humanity. #Science #ToBoldlyGo
It's amazing, I just can't comprehend how complex the construction is.
This is the best channel on RUclips.
Period. But, you can't measure how good something is :(
Brady is awesome at asking clarifying questions!
big thanks to Brady for mentioning that the construction was "sped up".
only "slightly" :D
Seeing this guy wear a helmet standing in front of all that makes me so happy. It looks like the future and I'm here to experience it! Just imagine what we'll be doing in 15 years.
The most informative video I've ever seen at the LHC, thanks! Just make sure that you don't leave Brady behind without a safety key!
Unfortunately no picture does this monstrosity justice. I felt like a little child when I saw it, just starring at it in total awe.
Every minute there are 24 hours of video uploaded to youtube, on average. No one will ever see every video, it is impossible. But I agree, Brady's videos and channels are amazing.
Kinda makes you giddy to see such a gorgeous machine.
It'd be fun to put an apple or something at the location where they shoot the "beam dump" and see what happens to it.
There's really no point in that because even 10^11 protons are ridiculously few and carry extremly little energy, again most of the protons would miss the molecules that made up your replica. If I remember correctly they just slam it into a lead wall and collect some data off it.
Funny fact to the ATLAS detector (and any other particle detector of that magnitude): Even the network cables around them are measured to the µm precise to reduce transfer times
Show us the beam dump please! I've never seen any coverage of it, but it's fascinating.
I'm an American teenager, but it's my absolute DREAM to work here :D
Is there any footage on this channel or elsewhere of the thing actually running? Not the beam itself, of course, but just the machine humming and the data being transmitted and etc.? Like surveillance footage or some such? Or do video cams somehow get fcked up by all that collateral from the collisions?
I can feel the excitement. It's the closest I'll ever get to it.
Tweeted. His enthusiasm is wonderful. You've got a great job Brady, and do wonders with it.
There are many videos on-line of the LHC "in action." Also, you can find real-time updates from CERN regarding the status of the beams, etc. CERN is incredibly open about how things work. I'm wondering what you'd expect to see.
I'm not smart enough for such science like this, and that's why is amazes me every time I think our species has created the means to do difficult and intricate experiments. Just wow!
ohh man wish it went for longer, Great job Brady
And what all this comes down to is to find the number 42
How do the two opposing beams get brought together to collide? If the beams are speeding up in different directions when are the "points" switched to force the beams to collide and how? What makes the protons in the first place - what kind of atoms are the protons from?
i love all these CERN vids as i was there on a school trip not so long ago.
although we didn't get to see the actual LHC or the detectors. but its still nice to think i have been what your looking at and showing people
very nice to come back to a time when the Higgs event was still under debate and being checked
Coming from the most recent video about the proposal of the new massive LHC, its almost sad to see just how optimistic physicists were that the LHC would find dark matter and confirm super symmetry. Like there wasn't a doubt in their minds, this was the machine to do it. I guess thats how science goes though, and I don't think anyone could make the claim that the LHC was a bad investment. Even without confirming these specific theories, the amount of knowledge and understanding this machine gave us is worth more than the price tag. Even more important, the amount of press and recognition the higgs and LHC brought into public view is something money can't buy. I wonder just how many thousands of students entered their PhD program just because of the LHC alone. So many kids were inspired by this thing, its a real beam of light. Its sort of like the Apollo program in that sense, it got people into science.
how do they isolate those protons? i'm asking this because for as far as i know protons are usually a particle in a complete atom right? so there would have to me electrons and neutrons involved aswell in those collisions right? can someone explain this?
The security is in the LHC not for preventing all the technics--but also to prevent YOU against all this LHC ZOMBIERS crawling through this damned tunnel!"!!!!
Awesome! So there is hope for humanity yet... :)
Sometimes you just gotta step back and look at the bigger picture.
People need to be reminded of that from time to time.
I'm not sure if I understand your question but I'll try to answer anyways. The reason why they travel at nearly the speed of light is because of their weight, without any weight they could travel at the speed of light. As an object gets faster it also gains mass which works to slow it making it impossible to reach the speed of weight regardless of how little mass you have. The ones that hit however are broken into base particles that are scattered and (hopefully) observed.
we've got a video coming on that!!!
Great tour!
i still don't understand why i love this channel so much...makes me wonder if i should go take a class in physics....
wow, i live within 5 minutes of the tevatron but this is incredible
I'm just in med school and this stuff is way over my head, but, man is it exciting. Striving to unlock the secrets of the universe... Are you not entertained?!
ah Gordon, weren't you supposed to be in the test chamber half an hour ago?
This is the kind of stuff that made me love science when I was little. :)
"They will never have the chance to be involved in a collision" in this context: sad
in pretty much any other context; really good!!!
Your videos ARE the best on all of RUclips!
Saw another large hadron collider video and was like uughhhh.. THEN i saw it was sixtysymbols! You guys really are the best
its unreal that we can build something like this, it's incredible :O
These particle collision wall paints are beautiful.
And to think that a machine like this (but even more powerful) was planned to be built in Texas and they canceled the project. What a shame and what short sightedness. :(
Great question. Once the beams have been around so many times, and been through all kinds of abuse, they start to go a little wonky. They dump them out at a minimum beam energy to prevent even the slightest bit of wonky-ness from developing... Which is the last thing you want in a beam. Basically, you dump it while it is still fully controllable, you don't wait for it to become a problem because you might have a microsecond or 10 before bad things happen.
That was a really nice explanation of the collisions.
Because Imagination and human creativity is being celebrated every time a proton is smashed to oblivion. Human ingenuity is something absolutely worth celebrating in such a royal and lavish way. (On a side note that is more relatable. Particle accelerates around the world do research on Bio-physics. So they produce particles that can target cancer. The knowledge gained is enormous.)
Thank you!! Questions I have been wandering about for a long time ia answered here! How broad are the beam? How many collisions pr second? And bonus: Only 20 of 'LOADS' of protons are colliding! Again, THANK YOU!!
The comparison with the reader was just to mention I know the technology exists to create something (like a tube) on a small scale. I wasn't saying that the length of the LHC was too short (it's needed to increase the speed) and I'm not saying to remove sensors (you could pretty much keep them as they are) I am talking about the chamber in which they collide should be funnelled into a chamber that is only a few atoms big so that there is less volume in the chamber specifically.
I can't thank you enough for these videos
The advantage of that is that you would have a much more narrow stream increasing likely hood for a collision because there would be virtually no area in which an atom could go past without hitting another one, like in an hour glass only allowing a few grains of sand through at a time. I asked specifically because I would assume there is a specific reason they chose a much larger chamber as opposed to a narrow chamber with a higher probability of collision
Good question. Nearly all the running cost is getting the entire machine ready for collisions in the first place. The actual beams are not that expensive to produce. Keeping them zipping around the LHC is the hard part. Try cooling down _anything_ to 1.8 kelvin. Now, do it across 27 kilometers! The beam gets dumped all the time and basically produces a bunch of useless particles and heat.
Yeah, although it wasn't put politely, he kinda has a point. Much as I love what they're doing at the LHC, I think the ITER project is more important for our immediate future. It was delayed by several years due to budget shortfalls.
I understand why you think that. But think about it this way: Those guys are experimenting at the frontiers of known physics. It's true that there aren't yet that many practical applications (although antimatter is an excellent candidate for efficient energy production!). But that doesn't mean that it doesn't have lots of practical applications, it's only that they haven't found them yet (bear in mind, they are only starting!).
No, not as far as I know. It really is called "Large Hadron Collider", because it is that huge assembly of instruments. I don't know if there even is a distinction by size between hadrons, at least never heard of it.
Great question. I know the answer, and the comment system at YT is not nearly big enough to explain it. Basically, they use magnets to control the beams. When they are ready for collisions they ramp down the magnets separating the beams. Also, it is highly important to prevent beam loss (it smashing in to the side of the pipes). There are a host of ways they try to avoid this. It gets complicated really fast.
its unreal that we can build something like this, it's incredible but cant stop killin each other for papper
There have been many been dump experiments at various detectors at other coliders. Two main roadblocks are 1) interest. 2) money. There actually are some experiments at the beam dumps, but more engineering tests and general theoretical work with beam control, etc. There may be more going on... but I am not aware.
You need the size because many of the particles generated pass through matter and only have a small chance of interacting. If you got only one sensor layer, if it passes through and did nothing, you lost it. So sensors are stacked.
Then there is no single detector, which can detect every particle. They are very specific and different types are aranged in layers.
you also need cables, structural support, temperature control, a many more things.
And why would it be called LHC if it was small ;)
How do they just "Take a couple of protons" and make them run around the beam? This thing is so complicated I have absolutely no clue how anyone could ever build something like that. This is mindblowing...
Yup.. that's right. There's a calc on the CERN website (can't post a link, but I just searched for 'LHC+mosquito').
This is why I LOVE SCIENCE
It's so beautiful!!!!! ❤️
There are a lot more bunches than just 2. They way they control where beams interact is at specified interaction points using magnets to steer them.
You should tell us more about the other experiments and detectors.
Awesome videos!!! Always looking forward to them, especially the LHC vids! That thing is just humungous!
Watching this video gave me some hope for humanity. Watching the ad popping up "Speak to a psychic" made me loose it again.
If you doubt the applications of quantum mechanics and particle physics, think about this: The transistor only exists thanks to quantum mechanics. Transistors are in every piece of electronics you see. If it weren't for research in quantum mechanics, we'd still be using vacuum tubes in electronics, and your cell phone would be the size of a stereo.
Good call on naming that music used at that point of the video.
CERN's home video producers are a bit Route 1 when it comes to public domain music: The Planets, the Flight of the Bumblebee. Does it begin with Beethoven's Fifth and finish with the Ride of the Valkyries?
Funny thing is, this thing must consume vast amounts of power. If all the dosh was spent getting fusion sorted as a power source first it'd been far less draining on resources. So despite the fact that the keyboard-warriors (most of whom probably only ever saw a lab at school) decided to hide your comment, I think you make a valid point.
Wow. Just ... wow. Anyone who knows me knows how difficult it is to get me to shut up about just about anything. But to leave me speechless from the opening gun? Just ... wow.
Not really. A neutron is formed of three quarks, the Higgs boson is something entirely different. But energy is a form of mass (e=mc2) so when the protons (also formed by three quarks) collide, the energy is transformed into other particles that did not form part of the proton at all. That's how you get the Higgs, photons, muons and so on :)
Because they are attached to the building plus the container alone probably weights enough to counteract the difference between the density of He and air.
great vids and explainations of the LHC
it was a small hutch for equipment while people go through some of the security stuff!!!
new particle discovered at CERN- talk about that next please
That bit about dumping the beam, it sounds like there are some missed opportunities there. They should set it up so that the beam can be dumped into a target area where they test the effects of the beam on various substances. Like, say, a meat-based replica of the human hand.
best LHC video, thx!
Build a collider along the earth's equator and name it Gigantic Hadron Collider
even if we had the resources, there is the problem of the tectonic plates
EagleGwaihir How about have it orbit the planes in low earth orbit
if you watch one of vsauce's videos you can find that a structure constructed around the earth would be unstable from varying gravitational forces along the earth
Put a book under it where it's unstable.
No. Equatorial Hadron Collider. It's just an imagination, not a potentiality.
Love the episode! Thnx 60symbols
This is an amazing video! Thanks and keep posting!
That makes a lot more sense, thank you!
So far that hasn't happened, and it isn't very likely to do so. But I talked to some physicists at ATLAS/CMS and they said they would love for this to happen. Apparently there is no danger, as those nano black holes would very quickly disintegrate.
Peace ! Theory is some times bringing the experiments to math. Sometimes the math is brought to practice(neutrino and more).What i want to tell was the nice!! competition between theorie and experiment makes physics rock solid , nothing else.
Greetings
Thomas
The record is something like 10-15 minutes (can't recall actual time). Work done at CERN, actually.
i realised i might be a nerd when i had "a little girl getting a new barbie" moment over this.
thanks sixty symbols! this made my day
Vsauce once came to your channel right? Well anyways, Vsauce brought me back! Kickass vid dude! EPIC Structure
Thanks for this.. don't know how I missed it. But thanks for CERN. Only thing it gives me worries about is that the last real news and interest push I've heard about ITER is years back. I'm wondering if these projects shouldn't be communicating, endorsing each other, or why we the public haven't heard about it.
6:15 is so humbling to think that us highly evolved intelligent creatures are still vulnerable to some of the smallest things in the universe
I've noticed the sixtysymbols course on iTunes U has got 6 videos last updated last year. Do you think it is possible for more to be uploaded onto it and it as very helpful resource, especially meaning you can view the videos any time.
Luminosity? A static target gets you only half the energy per collision, but if you can increase the number of collisions by a huge factor, why not install a small detector there?
At last, a RUclips video showing something where people can properly apply the word "AWESOME"!
How many safety keys do they have? I assume there must be quite a number, to ensure that they always have enough for the staff (if every staff member carries one, that is).
There's so much that makes me frustrated about humans. But when I see something like this it makes me love humanity more than anything!
The clip where you show the helium tanks was on another video on periodic videos, when DID you go to the LHC and why have you been holding out on us for so long? ;)
Interesting stuff. Thanks for posting!
You should make a video on the double slit experiment
i love the vid, woulda loved to see it for myself though. Its an amazing piece of machinery, even if the Higgs theory is disproved, which I find doubtful.
