Beyond the Higgs: What's Next for the LHC? - with Harry Cliff

In 2012, the announcement of the Higgs boson made headlines around the world. But what has been going on at the Large Hadron Collider since? Physicist Harry Cliff will be your guide. Want an update on this video? Watch this next: • Upgrading the Particle...

What is the future of the world’s biggest physics experiment? And what intriguing hints of new physics are around the corner?
Harry Cliff is the Science Museum Fellow of Modern Science, which he reckons might be the only job title which begins and ends with 'science'. He spends half his time searching for signs of new physics at LHCb, one of the four big experiments at CERN's Large Hadron Collider. For the other half, he indulges his love of talking about physics at the Science Museum, where he develop exhibitions, events and online content.
This talk was filmed in the Royal Institution on 31 October 2017.

Harry Cliff is one of those physicists who explain the most complex topics of physics in a brilliantly simple way ......just loved his presentation

[@lynx141]

[@paulmichaelfreedman8334]

If a leptoquark is found, that would be very very significant, maybe even more than the Higgs. But preliminary estimates/calculations put the energies needed at way above what the LHC can now produce, and an upgrade is not planned until mid 2030's.

[@taketimeout2share]

Yes, I agree with you, but I like the idea that they admit they are never going to get it completely right. As they find out more, they try to adjust their theories. And they are theories, not fact, and always say so, unlike those who insist their way is right, perfect and cannot be altered or improved on, like religion, or the political dogma of an intolerant tyrant. But I do wonder if they ever admit that it might be better to start from scratch, rather than pile more on top an already top heavy theory.

The existence of a rainbow depends on the conical photo receptors in your eyes, to animals without cones the RAINBOW does not exist... this is pretty amazing especially considering that all the beautiful colors you see represent less than 1% of the electro magnetic spectrum..... now think about what is there but you cannot see. that is basically what the collider is finding out... i will be applying to your team within the next 7 years, as physics is what i urge to know.

It seems that some of Einstein's comments reflected his suspicions of this and that his sense of understanding was deeply intuitive.

If you needed to be entertained in order to become a physicist, you likely did not have the requisite interest in the subject. That especially holds true for the idea floating around in the 90's that we needed more young people going into science, so we ought to go round to schools, performing science experiments that created loud and impressive explosions to get young people interested in science, without asking whether if that's what it took to grab the attention of students, did they really have the mindset necessary to be a scientist.

And please, please - if the lecturer refers to the slide - please, point the camera to the presentation, so that we can follow the explanations with the picture in front of us. Because normally, if the lecturer points towards the slide and talks about it, standing 90° next to it in order to directly show parts on the slide, you would look up there. And if the camera doesn't point there, then it is a bit frustrating. In the Q&A to this video there was even a part (13:11) where you could see the lecturer with the laserpointer in the hand gesturing towards the presentation - that was not shown. That's really not optimal at all. Really, even afterwards you couldn't see the slide - probably the responsible person thought that everyone should still have the slide in memory. But the lecturer extra went back to that foil to show everyone - except us - on that slide his point. Really, you should improve that, that's really destructive to the lecture as a whole.

As usual RI does a super job on a difficult subject. Harry is excellent. His English is spot on. I just really love RI channel. The ads are not over bearing the content is world classy! RI is No Ka Oi! Thanks because in Hawaii there is no other way to get updated on the progress on the standard model.

Thanks so much for putting the links to the original NASA videos in your description!

wonderful presentation. I could actually understand. great explanations. thanks for this.

Great talk Physicist Harry Cliff about LHC development ..!!

[@siccmade425]

Does ATLAS stand for "Aperture That Looks At Stuff"?

[@rumblehansi]

I see what you did there

[@unbroken1010]

No

They make theories, then they prove those with experiments. The tools inadequate to prove those theories? Worry not, the indirect ways can still save the day. Mind. Blown. I'm the very definition of a layman, yet I feel I've understood plenty. Harry Cliff is a gifted teacher. Many thanks!

Excellent Speaker, an update on the Large Hadron Collider's newest discoveries since the Higgs is welcome news indeed.

Clear and concise. Great lecture Harry!

[@geonerd]

This is one of the better public lectures on the channel. This guy is actually capable of coherent speech and communication.

[@Gohot229]

His humor' is unique... Piloting over most of the audience's heads with joke/humor....graduate physics humor... the audience was happy anyway, bliss.

[@ParadiseDecay]

As someone interested in Simulation Theory, stuff like this just makes it even more interesting.

Is the woman asleep at 50:24? I guess not everyone can find this stuff interesting but I for one enjoyed the entire hour of content.

[@brigritte2091]

she did it since min. 20:45!

[@andychauhan6544]

Sleep since the 5 min mark.

Outstanding video. Harry Cliff is a superb lecturer and teacher.

[@TheSYWY]

FANTASTIC piece of lecturing. Great knowledge , great flow to explain a very complex phononena in simple words. MORE from.him please!!!

[@zakirzak1494]

Great lecture for novice like me .... better understanding into the particle world ....many thanks for posting it

[@briangray925]

Very educational, I'm amazed at the great explanation on such an extremely difficult subject to grasp. If any one could find something fundamentally new and rework the standard model, my money is on Physicist Cliff,

[@varixman]

Great lecture. Really well paced, explained and structured with good use of visuals (they support rather than distract). Shame about some people in the audience, including the sleeping zombie-lady at the front...
