After getting my head under a shower of hot water this morning, one of my first thoughts was to wonder how the positions I had left on overnight were fairing. Which was swiftly followed by the thought of Schrödinger’s cat. Until I actually went downstairs and turned on my tablet PC, the trades I had open the night before could be still open or possibly closed; they could have made money or been stopped out for a loss.

Until I actually checked my charts, there was a quantum superposition for me as the observer of all possible outcomes. I had both made and lost money simultaneously.

Thinking about quantum mechanics, even for a little bit, can make your mind completely flip out. It’s great.

If you are not completely confused by quantum mechanics, you do not understand it.
