The humble proton may seem simple enough, and theyāre certainly common. People are made of cells, cells are made of molecules, molecules are made of atoms, atoms are made of electrons, protons, and neutrons. And protons are each made of three up or down quarks. Simple stuff, right? All except for that last part. Protons are actually made of many, many quarks that happen to look like three only when we look at them in a particular way. And even then, sometimes theyāre made of 5 quarks - including the charm quark.

Thanks AI for telling us that we all contain intrinsic charm.

What's great about these particle physics experiments is that we're unlikely to run out of protons to disassemble in the near future.

Thanks for explaining how machine learning is used in particle physics. This whole series is a rare gem in YouTube.

This is so well explained and yet so packed full of great details. It's overwhelming in a positive sense. This series deserves every educational award out there.

Well, I dunno much about protons, but Bing told me The Big Bang was an explosion, and when I told Bing it was actually an expansion, Bing told me to change the subject. I still have the feeling that I hurt its feelings.

This helped me understand particle collision experiments better than I ever have before. Well done! Very clear and engaging presentation

Love this channel. I'm not up to speed on all the physics but love learning new things. I usually walk away with new knowledge and a better understanding of the subject matter. Thanks Matt. Great job as always..

I do not think intrinsic charm quarks can exist but It is possible that even at a low energy collision, when the proton is destroyed the energy which was keeping the proton together might have been released might have made a charm quark.

IĀ“m a theoretical particle physicist and I really appreciate the precise way (and not boring at all) you bring the subject! It is rear to see a Physics Professor that brings information in such accessible way!!

Big thanks to the early gang! Because as noted a few episodes ago: Since our comment response livestream, we've noticed that YT isn't sharing our videos as much with our subscribers. So we're asking our subscribers to 1. switch their subscriptions from "PERSONAL" to "ALL" (just click on the subscribe button and you'll see it) and 2. Watch new episodes as soon as they can!

I always love how you make some of these tough topics easier to understand.

Another amazing video! The explanation is so clear and concise, and the visuals are stunning. Keep up the fantastic work!

Update: The audio problem seems to be with the YouTube's processing of the video. Thank you for bringing it to our attention as we can now discuss the matter directly with YouTube. We will pay special attention to the audio in the coming episodes and do all that we can to deliver you high quality experiences while we work to find a resolution to the problem.
Hey Space Timers! There seems to be an audio issue for some of our audience members. There may have been a processing error as it's not occurring for all of our audience nor does it seem to be in the original uploaded file. We're going to keep investigating and see what we can do to fix this. In the meantime, we hope you enjoy the content of the episode despite any technical issues you may be experiencing. Thank you for your support!

I've also noticed my intrinsic charm vanishes almost as instantly as it arises, whenever i speak.

Wow, I actually understood Matt O'Dowd on 2x speed without rewinding, finally. That's a first. :) It may never happen again, but it happened once! :D
I usually have to rewatch his videos several times at a slower speed to really digest the material because it's all so new to me and so very complicated.

Used to watch PBS space time 5-6 years back.. good to see you guys are still going strong. Keep it up!

I am made of hopes and dreams.

This is one of the hardest topics to visualize, yet your team managed to do it well!

Incredible job of making this complicated topic very approachable and understandable by those of us that are not particle physicists.
