Inside the Proton

3 sessions, in order

The three pieces everything is made of, the 27-kilometre machine that smashes them open, and the field that gives the smallest particles their mass.

1.P&A-66Three Pieces Make EverythingPhysics & Astronomy~22 minWhat is everything made of, if you keep zooming in? Two kinds of quark and the electron build every atom there is, and the whole known list of particles fits on a postcard.
2.T&E-27The 27-Kilometre MicroscopeTechnology & Engineering~22 minHow do you look at something too small for any microscope? Smash things into it and read what flies out, which is what a 27-kilometre ring under Switzerland and France does to protons.
3.P&A-67The Crowd That Fills All of SpacePhysics & Astronomy~24 minWhy do some particles have mass and light has none? Space is filled with a field that tugs on each particle by a different amount, and in 2012 physicists finally made it ripple.
