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.
Brady is awesome at asking clarifying questions!
Great tour!
So, I'm new here, but I think this has officially become my favourite channel on RUclips.
ohh man wish it went for longer, Great job Brady
Awesome videos!!! Always looking forward to them, especially the LHC vids! That thing is just humungous!
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!
Tweeted. His enthusiasm is wonderful. You've got a great job Brady, and do wonders with it.
Your videos ARE the best on all of RUclips!
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
I can't thank you enough for these videos
It's amazing, I just can't comprehend how complex the construction is.
This is an amazing video! Thanks and keep posting!
That was a really nice explanation of the collisions.
Interesting stuff. Thanks for posting!
Show us the beam dump please! I've never seen any coverage of it, but it's fascinating.
great vids and explainations of the LHC
Love the episode! Thnx 60symbols
I can feel the excitement. It's the closest I'll ever get to it.
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!!
Saw another large hadron collider video and was like uughhhh.. THEN i saw it was sixtysymbols! You guys really are the best
That mans enthusiasm restores my faith in humanity. #Science #ToBoldlyGo
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.
This is the best channel on RUclips.
Period. But, you can't measure how good something is :(
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.
Unfortunately no picture does this monstrosity justice. I felt like a little child when I saw it, just starring at it in total awe.
That makes a lot more sense, thank you!
big thanks to Brady for mentioning that the construction was "sped up".
only "slightly" :D
best LHC video, thx!
This is the kind of stuff that made me love science when I was little. :)
Beautiful. Thank you.
It's so beautiful!!!!! ❤️
its unreal that we can build something like this, it's incredible :O
i still don't understand why i love this channel so much...makes me wonder if i should go take a class in physics....
we've got a video coming on that!!!
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'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.
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?
awesome stuff
wow, i live within 5 minutes of the tevatron but this is incredible
very nice to come back to a time when the Higgs event was still under debate and being checked
ii love the buzz your getting
could you do a video on the Majorana Fermion?
seems really fascinating
You should tell us more about the other experiments and detectors.
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.
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?
Great video . what is the source of the protons?
These particle collision wall paints are beautiful.
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.
Very cool!
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'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?!
Perhaps you could explain a bit more. In this video it's mentioned the higgs event maybe being detected, however in other recent videos on LHC they talk about higgs not been found yet and that there's quite a group of people there that suspect it doesn't actually exist. But if it does exist, the area in which it exists got a lot smaller over the year. Could you clear that up a little? What's the current status? Thanks
Good call on naming that music used at that point of the video.
Superb.
You should make a video on the double slit experiment
Kinda makes you giddy to see such a gorgeous machine.
awe inspiring facility, reminds me of Half-Life
I'm very skeptical of that. Could you provide some of the sources so I can read up on it?
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.
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.
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? ;)
Ah thank you for clearing that up
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!
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.
new particle discovered at CERN- talk about that next please
it was a small hutch for equipment while people go through some of the security stuff!!!
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.
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).
"They will never have the chance to be involved in a collision" in this context: sad
in pretty much any other context; really good!!!
Nice!
I have to build some RPC's(the muon detectors).for my bachelorproject
(everything what can go wrong, does go wrong at the moment... sigh)
Yup.. that's right. There's a calc on the CERN website (can't post a link, but I just searched for 'LHC+mosquito').
How serendipitous.
AWESOME
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.
Is there any energy recovery from the proton dump at the end? Or is there not enough heat generated?
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
is it possible to generate some extra energy from the rest protons on the "final wall"?
(like, for a cxoffe mashine or light in laboratory)
I maybe have a silly question here.
But I can't understand that if the protons can go around again, what stops them colliding somewhere else in the tube.
Is it two tubes or one and how do they control direction of the protons?
yeah new video
thanks for the tweet!!!
How come there are no videos of the LHC in action? I can never seem to find any videos of the machine being switched on and detecting the collisions. Anybody knows where I can find them? And why issit so difficult?
Could you mention something about the actual "investigations" of the collisions? I've heard that the amount of data generated is huge. Do they have 10,100,1000 people that look through all the data?
Thanks.
Cool I've been there last year, love Science ! :D
Your videos would really benefit if you had a wide angle lens!
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?
Come over a nice idear. Why not pop pocorn in the beam dump area ?
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 ;)
I dig the Holst in the background of the animation. (around 3 minutes in)
I'm an American teenager, but it's my absolute DREAM to work here :D
Thank you, perfect timing to regain my sanity after hearing about glass atoms on TV.
Does CERN offer any public tours?
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

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.
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 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
At last, a RUclips video showing something where people can properly apply the word "AWESOME"!
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.
Vsauce once came to your channel right? Well anyways, Vsauce brought me back! Kickass vid dude! EPIC Structure
