Can snakes see?

I’ve seen five rattlesnakes since I moved to Colorado, four dead and one that was quite upset with me. As I was walking yesterday I wondered, can snakes see? Here’s an answer from animals.howstuffworks.com.

LiveScience.com adds this information: “With the exception of a few species that have adapted to daytime hunting, most snakes do not see well. Generally they can see shapes but not details. Snakes called pit vipers can see well at night by an amazing trick. Their pits (one on each side of the head) sense heat (infrared light) like night vision goggles. These pits, not eyes, actually are thought to render images of prey in the snakes’ brains.”

A very nice quiet fan for a small apartment

I currently live in a small apartment (about 700 square feet), and when I work from home I like to run a small fan to keep the temperature consistent throughout the apartment space. My work area is near the windows, so in the summer it’s significantly warmer there than somewhere else, like the kitchen. I’ve gone through several fans trying to keep the temperature consistent, but they were all too noisy, and became a distraction while working, and they were even worse at night when watching television.

So I finally pried open my wallet and spent $99 on this “pureFlow QT7” fan by GreenTech Environmental. On its lowest setting it runs at ~13db, so I don’t hear it at all. During the day I run it on a setting of 3 or 4, and it’s still much quieter than a normal fan, and not distracting at all. At night I run it on a 1 or 2 and don’t hear it at all while watching television.
