Finding the Higgs boson particle is a big endeavor—and in this case, "big" means "discovering it involves constructing the largest machine on Earth." The Large Hadron Collider is also the most complicated machine built in human history. Keep the instructions while you watch this lecture; some assembly is required.

This video is episode nine from the series The Higgs Boson and Beyond, presented by Sean Carroll.

“The trick to keeping them from heating up is to keep them very very very cold.” That was priceless 😎

It's a nice presentation and love that something like this was made because there is very little detailed video about how LHC works.
When I was there at the open day, the amount of stuff they had was way more than I can summarise here: the cryogenic system, the vacuum system, their own magnet factory and technology, their separate accelerator rings and straight line accelerators, their sophisticated detector technology and types, their data storage, their control room (more like a warehouse), their other experiments they are working on besides the main ones. Also the effort they put into material selection and testing is crazy. And I must have forgotten a lot of other stuff but all in all it's way more complex than people imagine.
I would love to see an hour long video on how these systems come together.

I love that the fundamental essence of is just the principle of slamming things together and seeing what happens. It's a principle that has served humanity well for thousands of years

[paulnolan]

It's just a phenomenal endeavour and achievement. Blows my mind.

[mdwoods]

What a great introductory explanation of the LHC.

[jimmyzhao]

If the tunnel for the LHC ran under my house, I would be sure to wear lead underwear for fear of stray protons frying my gonads.

[pmichael]

This is at least 7 years old. Would be nice to publish the date of the actual recording.

[Berghiker]

Great. That was in 2015. What about now in 2021? What's the current situation regarding the largest particle colider in the world?

[comment.highlighted]

Awesome presentation and graphics. Thank you 😃

[feynstein]

What a great presenter. I could listen to him talk all day 😊

[hockmengyong]

Awesome episode of physics ! Good to learn about this LHC from Sean 👍👍

[pitchforksarecoming]

Awesome presentation BTW, for us not as scientifically inclined, TY.

[boonteetan]

LHC is simply wonderful. It makes once practically impossible events possible..
A giant step forward for physics..

[ghahrai]

wish I had known at the beginning, that this video is from 2015 !

[marcosanaya]

Why was this posted so late if it was recorded in pre-2015? Either way, great video and content from Sean Carroll! Back to watching Arcane on Netflix.

[luap]

Great explanation. Didn’t understand half of it but very interesting. The layman here is just wondering how many demons from other dimensions have been summoned by this thing

[bipolarminddroppings]

I remember them talking about the LHC when I was at school. It really did seem impossible to build something so huge back then.

[robertbangkok]

I wish there were an update. This video is dated 2021, but was produced in 2014. What has happened since???

[jamesraymond]

The cost of the SSC in Texas was peanuts compared to what the gov't spent on covid without any benefit.

Enchanting presentation making CERN fascinating place to visit. I actually had a prized tour of the CERN just before the pandemic in 2019. Now I feel like short changed. Instead of asking for money back, I will go back again. This time I would like to ask for a real fascinating experience, perhaps a journal to commemorate a rendezvous at the gate to understanding ' that's what matters ' thanks for the effort and keep up with the good work.
