The Perfect Wave

Yesterday was the summer solstice (hope you Pagans out there had a good party!) and my boss showed me something very cool.

If you visit the offical US time website, and click on your timezone, it will give you the time where you are. More importantly, it will show you a map of the world, with which areas are currently in daylight, and which ones are in shadow. At the solstice, the shadow forms a perfect sine wave, which will turn into almost a straight line as we move towards the equinox, then a sine wave the other direction as we move to the next solstice.

Neat, huh?

Yeah, I'm a geek, but in a world full of wonders, its the geeks who go looking that see the most.

Back to work.
