X17 - A new particle? -- Sixty Symbols

Professor Ed Copeland discusses research into the so-called X17 particle.

Corrections from Ed:
"Around 4'40" saying the X17 particle came out with low momentum, I meant low velocity. Later on I said the X particle interacts differently with electrons compared to protons. I meant neutrons and not electrons but I said it right just after that."

Sixty Symbols videos by Brady Haran

[rrryan]

Just want to stop by and say that Sixty Symbols was the reason I gained an interest in physics and the sciences. I don't come from a background where I would have ever thought I had what it takes to study anything, let alone something that seems so complicated. But the accessibility of the topics and the way you all present them pushed me to get my degree. Just about to start my Masters in Astrophysics.

Thank you!

I absolutely love these calm videos with Professor Ed talking about possible new discoveries. They're perfect for a quiet watch during breakfast or right before bed.

Ed needs his own channel to talk at length about stuff like this, i could easily listen to him for hours at a time

18:58 Brady: "Are there X17's in the room with us?"
Prof Copeland: ...squints around in the room before answering...

I love the Professor Ed Copeland vids. He manages to explain these immensely complicated experiments and results in a way someone like me who just enjoys learning can almost understand

100 points for Brady, his questions are amazing!

[pj]

19:53 "That's a tough question" answers it anyway without hesitation

[deeprecce]

Professor Ed's tone and the speed of his speech is absolutely brilliant!! Great Video!!!

"So right now, there's no X17s in you?" - "Well, I often am quite excited".

[PenStep]

What an exceptional video. Calm (almost) understandable presentation by the best on YouTube, and incisive questions.
It doesn’t get much better than this.
Thanks to both of you.

[durvsh]

Brady as usual with very good questions.

[Android]

This was a super interesting episode. You got more into the weeds than usual and I love it. Professor Copeland is fantastic at explaining things in an understandable way without dropping too much of the complexities.

[neerajlohana]

Particle physics just gets more interesting with Professor Ed Copeland!🙌👏

I love it when the professors get a question from Brady and you can tell they think it's a really good question, something that sounds simple but really drives to a core concept. Brady, you're an excellent interviewer.

[Ruddigore]

A fascinating video. Prof Copland was brilliant in not only being able to explain the research behind the X-17 particle in a simple, easy to understand way but also in being totally unfazed by some of the tough and relevant questions being put to him by Brady.

[shkotayd]

Dr Ed always boils stupendously complex stuff down in a way I feel I can understand.

I never knew why this angle issue was a thing. Now I do!

Finally another video with Ed Copeland. I waited so long to see some more content with him. I just love his calm and precise way of presenting content. Great.

[carlstanland]

Professor Copeland explains things so well that even I can almost follow along.

[byrnemeister]

Great video. Well balanced views from Ed. It gives people some insights as to how we push back the edge of knowledge in the sciences. As well as the specifics around this particular particle and it’s existence or not. More of this sort of stuff please. Slightly longer format and a chance to go through some of the evidence.

This is by far the best material on this topic. I'm in the direct neighborhood of the Institute where the experiment was done. Still, Prof. Copeland and Brady did a way better job explaining the thing than any other resource I've seen on the topic. Thanks a lot!
