When we see, hear, smell, or feel something, what’s happening? How do we take in information about the world around us, and how does that information get to us?
When I smell the fragrance of new azalea blooms in my yard, actual microscopic particles emanating from the blooms themselves are wafting through the air, entering my nose, and interacting with my olfactory cells. Anytime you smell anything, there’s physical contact in the form of floating particles occurring between you and the source of the smell. Continue reading →
How can we know things? It’s an important question which isn’t as easy or obvious to answer as you might first think. In fact, it’s such a tough question that there’s an entire branch of philosophy dedicated to answering it called epistemology. But it’s not just a question for the specialists with their thought experiments and fancy terms; it should be a question that we all think about regularly. Why?

This is the infinite regress problem. The chain of causality in this cosmos of ours begs the question of its ultimate beginning. If our universe is cyclical, expanding in a big bang and then collapsing on itself only to then expand again, what started the cycle in the first place? Continue reading →
When I was a kid I lived in a neighborhood that was relatively safe to run around in and explore. There was a small creek that ran through the neighborhood, and I used to play on its small muddy banks. I’d take the route from my house that wound through my neighbors’ back yards, through dense foliage, between trees, and behind fences, until I could hear the faint babbling of the water and saw the sun only reaching the ground in a few thin shafts that squeezed through the dancing, leafy canopy above. The somewhat isolated creek had its own character and feel, and its banks and surrounding grounds became a secret garden. I was probably only a few hundred yards from my house, but it was a world away. Continue reading →
