Scale

Astronomy Now has a post up with a photo of the International Space Station and Mercury transiting the Sun this morning.  It’s always a good idea to get some perspective on the size of things.  On a much smaller scale, I drove up to the Sacramento/ San Francisco area from L.A. in December to work on a job with Dad and was reminded that distances in the West are a bit different than the Northeast.  The 412-mile trip up didn’t even get us out of California, but that same distance takes you from New York City to Cleveland, Ohio.  That crosses New York, goes across all of Pennsylvania, and takes you halfway through Ohio.  We visited Rhode Island, Boston, D.C, and Connecticut when my brother and I were in grammar school and everything seemed like it was just down the road.  The short version is: it’s worth taking a step back and really thinking about scale.
