A friend recently wrote an essay discussing faith. In it, he gave one of the standard definitions of faith as “A belief that is not based on proof.” The common understanding is that religious beliefs are examples of this, especially since religions tend to use the same word in related (although not identical) fashions. I think this is a good working definition for discussing matters of science and faith, but want to explore how it may miss some subtleties in how we really approach beliefs. Continue reading

Where’s the Wave Collapser?
This little video illustrates one of the big confounding questions in physics. The question is how to understand the role of conscious observation in resolving a quantum state. The problem has been around for a long time, and Erwin Schrödinger came up with this famous illustration to highlight the question. Towards the end, the video describes a higher-level perspective about the question. Continue reading
Sudden Phase Change
Imagine a basin of calm, liquid water. Perfectly still and pure. All of a sudden it is jostled, or a speck of dust falls in, and it freezes in a moment. The water must have started below freezing, yet it was liquid. This seeming contradiction can occur when very pure water is carefully lowered below freezing, so ice crystals never have a chance to form. The result is “supercooled” water. Supercooled water may remain liquid while cooled quite far below freezing. It’s easy to make in the lab or at home, and sometimes occurs in nature.
While the water is still liquid, it seems contradictory: below freezing, yet not frozen. If water below freezing is supposed to be frozen, why is this so easy to demonstrate? It just seems wrong. Continue reading
