I enjoyed the essay by John Mayer titled “Quantum Engines” in the Aug. 22 Addison Independent. Like him I am not a physicist, and like him I have followed the developments and ideas of physics as closely as a nontechnical reader may. So I’m not here to correct him on any points he made, but to endorse his curiosity and wonder at our advancing conceptual picture of reality.
