In Richard P. Feynman’s book, A Strange Theory of Light and Matter (Princeton University Press, 1985), collecting his lectures on quantum electrodynamics, an agreement between quantum mechanics and relativity is attempted by describing interactions between light (photons) and matter (electrons), which are thought to travel to and from anywhere in the universe at any time. Like other quantum field theories of physics such as string theory, quantum electrodynamics proposes that spacetime cannot be defined by the laws that once conceived of time as though it was an arrow moving through a distinct past, present, and future. Space is no longer conceived of as though its points could be connected by lines that do not exist in the natural world. A Strange Theory of Light and Matter is one of the foundational texts assigned in Rae Armantrout and Brian Keating’s breakthrough course, Poetry for Physicists, currently underway at the University of California at San Diego.
