When I began my master’s program in cognitive science, an electrical engineering professor told us—rather arrogantly—that the soul is nothing but neurons firing. “You’re deluded if you think otherwise ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
