    The Feynman diagram describes a neutron emitting an electron and a neutrino as it decays to a proton.
    The two equations are the Schrodinger equation and the Heisenberg uncertainty principle.
    The black-and-white photograph is a cloud chamber photograph showing the tracks of particles through the chamber; charged particles move in circles because there's a magnetic field vertical to the plane of the photo.

    The cloud chamber photograph is almost certainly a bubble chamber, and it looks like it might be the process p -> K+ Lambda.

    Yeah, I was about to ask what that was. It's unrelated to the Feynman diagram.
