Why Discrimination is Not always the Cause of Wage Disparity

Jumping to conclusions is something people do.  Let's take the case of wage disparity.  I have several acquaintances on social media who like to tout the difference in wage between men and women as an example of sexism and discrimination alive and well.  Now, with a new election coming up, both parties are touting their support for equal pay.  But discrimination is not the cause of wage disparity.  It's genetics.

A Wave of Anti-Entropy; from black holes to biology

It seems odd that we may be able to divine fate from mathematical rules, but classical physics describes nothing less than a deterministic universe.  According to Roger Penrose, in his massive tome The Emporer's New Mind, all of the classical physical laws, and even most of the quantum laws, suggest that time can be read as easily backwards as forwards.  "Newton's laws, Hamilton's equations, Maxwell's equations, Einstein's general relativity, Dirac's equation, the Schrodinger equation - all remain effectively unaltered if we reverse the direction of time," he says on page 392 of his ridiculously large book.  Indeed Penrose points out that the laws of physics provide predictions and are symmetrical regarding time; i.e. the rules are the same whether we go forward (t) or backwards (-t) in time. He goes on to say that, "the future determines the past in just the same way that the past determines the future."
