I just taught you quantum field theory in about 2 seconds.
The Secrets of Particle Accelerators (2018)
The higher the frequency the smaller they get.
The Secrets of Particle Accelerators (2018)
Particle physics, I said, was the foundation of it all.
The Matter of Everything (2023)
Physics will always be, at its core, about understanding our place in the Universe...
The Matter of Everything (2023)
What I'm going to talk about today is the fascinating world, and I really think it's wonderful, of particle accelerators.
The Secrets of Particle Accelerators (2018)
That's only one particle accelerator. There are actually over 26,000 of them in the world.
I want to go back to about the late 1920s and 1930s when a new type of particle accelerator was invented, called the cyclotron.
The Secrets of Particle Accelerators (2018)
I wanted to know how it was all connected and how I was connected to it.
The Matter of Everything (2023)
Alpha radiation won't go through your hand, beta radiation won't go through a piece of aluminum [a few millimeters thick] and gamma radiation is penetrating and won't go through a big piece of lead.
So there's some really interesting applications of accelerators, way outside of the realm of particle physics, that we're starting to get a handle on.
If you just put this beam onto a massive block of copper, you could actually melt 600 tons of copper from solid to liquid, just using the Large Hadron Collider beam.
But they did, in fact. One of the interesting things I discovered, they did put a particle accelerator in space, which I think is fantastic.
This is not a dangerous process.
I will leave you with some photographs of some of the places that my career in physics has taken me so far, and I hope to add many more to this list in the future.
The reason we can say today that we know all this stuff, that we think our theoretical models represent reality, is not because we have pretty mathematics but because we have done experiments.
The Matter of Everything (2023)
A lot of astronauts' food is irradiated before they send it up so that they... aren't going to get sick from it.
So that's 5 things you should never do with a particle accelerator. Thank you.
The amazing thing about this collection of particles, which admittedly looks arbitrary until you learn it in more detail, is that you can take the entire description of every known particle and interaction, other than gravity, in the universe, and write it down on a mug.
The Secrets of Particle Accelerators (2018)
This... is only one particle accelerator in the world... there are actually about 35,000 of them...
