One formalism developed by this man stated that weighting each trajectory of a particle by the action and summing over all possible trajectories gives the quantum (*) amplitude of a given process.
This man proposed a method of detecting gravitational waves by placing a bead on a stick and allowing the back-and-forth motion of the bead to generate heat. One formalism developed by this man stated that weighting each trajectory of a particle by the action and summing over all possible trajectories gives the quantum (*) amplitude of a given process. With Schwinger and Tomonaga, this man developed an extremely accurate theory which describes the electromagnetic force as due to photon exchange; that theory is QED. He also names a construct that uses straight and squiggly lines to describe particle decay and scattering. For 10 points, name this American theoretical physicist whose namesake diagrams are used to show interactions between subatomic particles.
