As a graduate student during the 1980's, I became fascinated by the colorful, but seemingly chaotic wave patterns exhibited by electricity in plasma bulbs. I soon concluded that the eratic wave patterns provided intuitive evidence of indeterminism in nature (though not proof). Thirty years later, I am still persuaded that indeterminism trumps determinism as a guiding philosophical proposition. This conclusion eventually shaped my views and approach to financial economics leading to an advocacy of stochastic modeling methodologies in research and practice.
I recorded the video that follows using a plasma lamp from my study and post it here for others to view and ponder. Notice how the waves respond as my finger touches the globe.
