Is quantum mechanics complete? Perhaps not. Adam Becker’s “What is Real?” makes a case for alternative theories to counter the hegemony of the Copenhagen Interpretation. The world described by quantum mechanics is a strange one. To fully appreciate its strangeness, picture this in your mind: Imagine a ball rolling down a track at a speed of 1 meter per second. Classical physics tells us this: if we can measure the position and velocity of the ball at this time, we can predict the position and velocity of the said ball at different points in the future. Even if no one is…
