Dear Humans,

I really like flags and kites and banners. Things that flap in the wind. Because they show us that the most powerful things in this world are often invisible. And while we can know them in many ways–feel the breeze in our face, hear the leaves rustling in the wind, smell Greeley carried in on an approaching snow storm–sometimes they’re difficult to really, truly see.

We talk about this in science all the time. Because science is the art of “seeing” things that we can’t really see. We do our best to see the invisible by observing closely related things and using complex and expensive instruments and collecting data, but sometimes the best aid to seeing the unseen is a simple piece of nylon flapping in the wind.

Sincerely,

Mr. Curt
