tan·gent ˈtanjənt/Submit noun 1. a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point. 2. a completely different line of thought or action.

I like tangents. Mostly thought tangents. They keep conversations interesting. Conversations without angles and curves tend to bore.

The same might be said for photographs. Angles and balances in photographs create eye interest or brain interest. Some say photography is not art. Some photographers say this. I disagree. The art is in the composure. Capturing a scene in a way that makes the viewer see it in a new or different way. The art is also in the subject. Deciding in the first instance what to shoot and what to ignore.

The angles in this photograph made me think of a protractor. Thinking of a protractor made me think how much of mechanical geometry has been subsumed by the computer. I wondered if we even had a protractor in the house. Our soon to be 11-year-old daughter came to the rescue. She had an entire geometry set.

We are living in a time of often praised technological advancements. So overwhelming is their onslaught, we forget how we got here. The world was circumnavigated, new lands discovered, old fables put to rest by fearless explorers who used only the wind, stars, protractors, triangles, and rulers to cross vast uncharted oceans while surviving unknown reefs and using only the color of sunrises and sunsets to predict storms.

Yes, I like tangents.
