Hey guys! We’re now live on Spotify🎧

Pick up anything at all and you can feel its mass without measuring it. Inside that object are protons, and inside every proton sit three quarks — and when physicists finally weighed those quarks, they came to less than one percent of the proton. So what is the rest of the weight in your hand?
Tonight we walk it down slowly: what a field actually is, why one field never rests at zero, why a quark cannot be pulled out alone, and how a supercomputer weighed a particle nobody can open.
Get cozy and let this slow walk through the origin of mass keep you company tonight. Subscribe to Nap Theory if you like your questions ordinary and your answers strange.
