Chapter 7: -Decay: The Rosetta Stone

The neutron exists . But physics is not only about being—it is about becoming. In this chapter we encounter the first quantum process: β^- decay. A single neutron transforms into proton, electron, and antineutrino—and in doing so reveals all five sectors of the force template from Book III. This single process is the Rosetta Stone of Category τ: one reaction, five languages, complete translation.
