free of the infinities that had rendered invalid: Bohr’s theory of the atom produces the visual image for light interacting with a hydrogen atom as shown in Figure (a). Bohr adapted equations from how the earth goes around the sun to the world of the atom. The lines indicate the spectral lines that emerge when the electron in the atom makes a quantum jump from a higher to a lower orbit.

The Feynman diagram in Figure (b) shows the same processes depicted in Figure (a)—a hydrogen atom being struck by light. The line EP is the state of the atom before it is struck by a light quantum (the wavy line E). The line ER shows all the higher energy states of the atom which the electron can be driven up to after having been struck by light. E’ represents the light quantum that the atom emits when its electron drops back to its ground state; it is the light split by a spectrometer into spectral lines.

The Feynman diagram is strikingly different from the image produced in Bohr’s theory of the atom. We would not know how to draw it without the proper equations—the equations of Feynman’s theory for how light interacts with electrons, the new quantum electrodynamics free of infinities.

a “sentimental painting”: Quoted from Enz (2002), p. 444.
