We are a way for the cosmos to know itself, at least according to the late physicist Carl Sagan. But how well can we really know ourselves if we forget about the sun? Or electricity? According to solar boat builder Dr. David Borton, not too well. If, like Carl Sagan said, we are made of star stuff, than we are electrified star stuff, human machines translating solar energy into sheer electrical force. Dr. Borton sat down with WOOC person Meghan Marohn for another episode of “Equality Under the Law: Practical Physics” to discuss machines, energy, and electric pulses threading through sensory reality.
