Desmos Graph Showing Parallax Experiment

Wouldn’t it be cool to have goggles that showed you exactly how far away from you a bird or a plane or a planet is? Here’s a first step at understanding the math behind a project like that, basically, understanding parallax. What else would you have to know? Would you have to know the size of the object first?

Continuous Creation

A religious philosopher living in the 1200s had an amazing idea: that God was continuously creating the world. For example, every time you looked outside your window at a tree, God was actively and continuously creating that tree. The name of the philosopher was Thomas Aquinas. During college, I remember how in my ethics class, the professor spoke passionately about this idea of Aquinas. It’s a beautiful idea. The notion that we are all held up in this act of continuous creation. Interestingly, it might not be too far off from what science tells us, if you put aside the question about the existence of God for a moment, and talk about existence itself. In physics, Einstein’s famous equation

E=mc^{2}

tells us that mass and energy are connected. In this podcast, at 17 minutes and 10 seconds, they are discussing this notion of the effort or energy that goes into anything existing, even for a moment, which seems like a parallel to what Aquinas what describing, at least taken figuratively.
