A Word About “Time”

Unlike most things, time flows in only one direction. Physicists say that all the equations of quantum dynamics, and many other things, work both forward and backwards. Think of the commutative rule in high school math: 3×4=4×3 and 2y=x is the same as x=2y. But time goes only forward. Keep this in mind when you write about time. Here’s an example of the National Oceanography Centre doing it backwards.

How has the ocean changes since the Miocene?

Okay, first, the typo in the headline. Should be “changed.” Have I ever mentioned that you should proofread???  Harrumpf.

Now look at that from-to construction in the text (emphasis mine). “From” is where you start, “to” is where you’re going. They have it backwards! Sounds like an exciting adventure, though!
