Sixty Symbols videos by Brady Haran
Professor Copeland's genuine joy and enthusiasm here is contagious :)
He's one of the best at being enthusiastic and passionate while teaching, it seems!
YES!!! The day any Brady video is posted is a happy day indeed
This is shaping up to be my favorite sixty symbols video series. Thank you so much for putting in the work Brady. Can't wait. I hope these videos are around a long time so when my children are old enough they can watch and learn as well.
I'm not smart enough to understand exactly what you guys are talking about, but just smart enough to appreciate that you guys are doing something great for rest of the humanity.
Keep on it!
I can't say this enough, thanks for taking the time to make these videos.
"This is the one that's gonna get the Higgs." That part was great. Another fantastic video!
Magnificent! I'm so excited and jealous that you visited the LHC, can't wait for the videos. Just also wanted to say thank you for all these videos you produce (including your other channels of course) - they are top quality, free to watch, educational and entertaining. Everyone involved in making them should be given some kind of of national honour for services to the community. Best thing ever to happen on TH-cam!
One of the best things on the internet thanks for the time and work you put into this.
Professor Ed is awesome, more videos with him please 🙂
@SmallMcLittleTiny Asking questions is the first step to knowledge, well done!
This video is like the perfect gift for the weekend - thanks Brady!
This is very exciting and interesting. Brilliant questions as well Brady :) I was thinking the same things myself.
It´s charming when he gets excited by a topic, but i think i have never seen him that happy xD
Videos are awesome Brady, they're a great insight for a social scientist interested in the social impacts of technology and science (since we're renowned for sucking at math and stuff, vulgarization of pure science is pretty awesome!) Prof. Copeland is always such a delight to listen to! He has a way of making particle physics comprehensible to someone with no physics background whatsoever, it's pretty amazing when you think of it!
Lovely area. I'd love to visit it sometime. As a machinist, I'd appreciate learning how some of the tubing and fixtures are made. I assume that they would require pretty close tolerances. Great video.
Brady has an outstanding talent to enquire.
i love how exciting he sounds when he's explaining it.
I noticed how at about 10:19 when you dubbed yourself in asking the question you put some bird sounds over it. The really sneaky part though was the bird sound over the natural audio at 10:14 to make the birds on the actual dub seem less out of place.
Things like that seem silly when they're pointed out but they're part of what makes it all seem so natural. I've been watching for years and that's the first time I've noticed something like that which shows how subtle it is.
Pretty slick.
Already have. I've watched all their Channels and their vids!
@ThoughtfulGeek Yes, exactly. Essentially the closer you get the more energy you need, but when you're very close to it, the jumps in required-energy are tremendous.
amazing stuff, can't wait for new videos
Great explanations. Thanks Brady and Ed :)
You're the man Brady, you're the man
@frozenfire the bradyharan website has them all listed.
I enjoy these videos so much! Thanks Brady!
Mr. Ed Copeland is wonderful! I love your editing too on this, Brady. So hilarious!
This reminded me of the Tim and Eric Awesome Show Great Job
@macikosan glad someone noticed after I made them pull over to get the shot!!!
Really interesting, I'd love to go there.
@NavjotGraphicDesign The sign signaling a roundabout is an analogy to the LHC, which is also circular.
@AlanKey86 you're welcome
@Mrjesse451 well you'll be pleased to know another will shorty be posted to DeepSkyVideos
- Brady
Love the ending bit.
no, as they their velocities are vectors, so they point in the opposite direction. so they cancel out as they collide (and transferred into the subatomiv particles--> consevation of momentum).
I'm so happy I've been down in the LHC, walking through the tunnels as it was being built, amd actually being in the room where ATLAS was being put together. This was back in 2005, I believe. It's a massive construction, to say the least :)
The nickname for the Higgs is from a book called 'The God Particle' by physicist Leon Lederman. He nicknamed it because the particle is "so central to the state of physics today, so crucial to our final understanding of the structure of matter, yet so elusive," but jokingly added that a second reason was because "the publisher wouldn't let us call it the Goddamn Particle, though that might be a more appropriate title, given its villainous nature and the expense it is causing."
@OPBjorn yep
amazing video!
Fascinating.
Yesterday i was at Geneva and i think i passed by prof. Ed Copeland!!! :D we were over the large hadron collider!! can't imaginee!!!!!
awesome vid guys.
Watching this instead if studying for my electromagnetism exam. I regret nothing!
@wvhdogg There's a sixty symbols video for that. I believe it was the Viewer Questions.
Only a particular expectation of it. But not completely yet. There should be a "Five Sigma" video on here that gives you more detail about that.
I love the professor! He's like a happy child playing with the snow...imagining creating boson particles
Thank you for another great video! I have one question that I think would make a good vid. Why can the lhc get particles to 3m/sec from the speed of light and not more? How much energy would you need to do that? Thank you
@Solipsistically one a week for the nest few weeks, unless something else pops up that is more time critical and jumps them in the queue.
Hey Brady, can you please make a video on the standard model. It seems like a very large subject but I think one of these videos could do it.
I wonder if it's too difficult to explain why certain particles decay into others in a particle collision. I was wondering the same question you (Brady) asked at 7:57: Why this or that particle decay/conversion after a collision. Another related question I'd love to have an answer to: Do physicist know WHY some paths are easier than others? If there's a simple way to explain all this (maybe a couple of decays that fairly simple) I'd LOVE to watch such a video.
Ed SMASH!
@Carutsu That's not censorship, that's called "editing." Editing is the process where an editor changes the author's wording in order to improve the writing, or to comply with the editorial standards of the publication.
@macikosan Could you please indicate what your talking about. I am really interested in knowing.
Can you do a video of "lepton" first time i hear of it was in this video (then i look it up) and now I'm curious
\\Thanks
Thanks for this great video, I really appreciate it!!
"Built on the cheap."
Relativity makes sure that their relative speed doesn't exceed the speed of light. If the particles could observe the event, they would each see the other particle approaching at less than the speed of light.
Question: After all the collisions, are leftovers inside the tube? or all the particles involved decay into photons and neutrinos?
I can't wait for the video of Ed Copeland talking particle physics next to the LHC. :)
What sorts of ions do they collide? Also, I'd like it if you discussed the pictures of all the jets and did a walkthrough of an analysis. ;)
There have been a couple of groups reporting possible Higgs appearances, but what he was said was that in one particular regime (meaning a hypothesized model) you'd expect to see a Higgs once in 10 trillion collisions.
@NavjotGraphicDesign My comment was about how clever the shot was of the roundabout sign near LHC, it looks a little like a sign that says "warning LHC ahead", it made me chuckle. I'm not sure how many people got that.
So here is one for the conspiracy theorists, what if there is a particle accelerator under ever roundabout, and the signs are just telling us ? WOW - Mind Blown!
I've got a question. I'm going to be close to Switzerland in a few weeks. Can anyone drop in to CERN or is it only by invite?
It's not really the relative speed that matters. What matters is the amount of kinetic energy you can pack into each particle. When each particle's speed approaches the speed of light, adding more energy to the beam no longer translates into an increase in speed, but instead the mass of the particles increases in accordance with the energy-mass equivalence that we know from relativity. There is no theoretical bound to how much energy a particle can absorb this way.
You should do a video on LIGO (Laser Interferometer Gravitational-Wave Observatory)
@realolba There is something called the beam dump that I would love Sixtysymbols to do a feature on. Getting rid of protons with that much energy is no joke!
One thing I've never really gotten is: what differentiates the energy from matter? I mean, on a basic level, mass, taking up space, yeah, but what's the exchange there? Is it energy density? If you stick enough energy in a small enough point does it turn into particles? I've not come across any answer for this.
@d0ntr4p3m3 The Professor also mentions statistics that stand behind this statement, so I take it's just a theory so far.
Even if Higgs Boson occurs, it's not going to be detected at all occasions - the detectors are not everywhere inside the LHC. Also it might decay before it reaches any detector, which is a kind of random event too.
I'm not a specialist but that's what I assume.
So if you walk in the opposite direction of the beam at some point it will be going the speed of light relative to you? I assume this isn't true, but I don't know why.
What is amazing to me is they could even have built something to detect these small particles at the speed they are traveling at.
@MetalheadMr666 you're welcome.... it was a tough sacrifice for us to go to CERN and make it for you! ;)
Where do the protons and neutrons used in the experiments come from?
do the resulting particles of a collision differ how the protons hit each other, like, is there the equivalent of a grazing shot, etc.?
Can anyone explain how the detector is able to detect fundamental particles? I mean, it can't just make a picture of it for sure.
Top stuff, as usual.
Is this the final video from the LHC? or is there any footage from inside the LHC itself? great vid btw!
The speed can't go past the speed of light. So if I'm not mistaken, it's only the energy of both beams that is effected.
I LOVE HIS HAIRLINE
Love the bits of PSSSSSSC (Pathetically Small Scale Slow Speed Snow Samples Collisions).
Your finger is just starting to block off the objective light that is focussing on one part of your eye, whilst letting through light focussed on another part. makes it seem like its bending. Short sighted people use this trick when they squint to see better, It removes the unfocused light, leaving the object more in focus
are some of you guys from numberphile too? If so you guys are awesome, i love these vids and the ones on numberphile, and i think you guys do a good job
Thank you Brady !! Seem you great fun with the smashing snow part, i really laught
how long does it take to switch from protons to ions?
Special relativity does come into play. You should check out minutephysics' latest video. Part of it talks about how special relativity comes into play when you calculate relative velocities.
Common misconception. If 2 cars are traveling directly towards each other at 70 mph and collide, the collision is NOT the same as hitting a wall at 140 mph. It's like hitting a wall at 70 mph. Mythbusters even did an episode on this. Check it out! It was a good one.
nice explanation
Lmao @ the montages of the professor smashing the snow together
@AlanKey86 Because a 15min video is considered a gift and will make you happy for an entire 2 days....
Professor Ed Copeland you are f** good explaining physics!
hehe.. Like your experiments in the Small Snowball Collider! :-D
Do where do they get all of these protons?
Ed is such a lad
Special relativity is involved at such high velocity. Velocity addition isn't so simple, as is the case in non-relativistic situations. We have to use a correction factor that takes into account the speed of light.
It depends on how fast you make it go. That's like saying "What's the speed of a baseball?" It has no intrinsic speed. Only light has an intrinsic speed, and only when we refer to it in a vacuum.
I love Copeland
please talk about the Lorentz contraction that these protons and ions are undergoing at nearly the speed of light.
I imagine that many of you are already aware of this, but Hank Green has a song about Quarks.
Watch it.
You will thank me.
@EliGudi Do you really need to ask that? Even though the video told you the answer?
@Carutsu Thanks man! I was about to write that same comment. I wonder why prof. Ed didn't know that ;)
4:18 "Get some protons and uuhh.. get some more protons" Classic
How do you get and isolate a proton?
