Space Between Philosophy and Physics
The Bell Theorems, together with a collection of experimental results (such as those of Aspect et al.), provide good statistical evidence that quantum theory is “non-local.” Roughly, this means that…
Time-reversing a classical Newtonian trajectory is simple. If q(t) and p(t) are the positions and momenta of a particle on the trajectory, then time reversal flips that trajectory as follows:…
Can you visualize a normalized wave function on spacetime? Let’s try with a simple example. The role of a wave function is to assign a complex number to each point…
Bill Unruh’s recent collection on black hole analogues begins, Deep beneath the great encircling seas of the Discworld lived a species of hyper-intelligent fish. (Unruh 2007, p.1) Unusual, but inspiring:…
