[[A stick figure lectures]]
Figure: There are four fundamental forces between particles: (1) Gravity, which obeys this inverse square law: Fgravity = G(M1M2)
Figure: (2) Electromagnetism, which obeys this inverse-square law: Fstatic = Ke (q1q2)
Figure: ANd also maxwell’s equations
Off-panel: Also what?
Figure: (3) The Strong Nuclear Force, which obeys uh… well, umm… It holds protons and neutrons together.
Off-panel: I see.
Figure: It’s strong.
Figure: And (4) The Weak Force. It [mumble mumble] radioactive decay [mumble mumble]
Off-panel: That’s not a sentence. You just said “Radio-
Figure: -And those are the four fundamental forces!
