This is no place for an observatory

Rushing into night

Originally drafted back on 11 August 2007 in Preston

Laying in bed last night looking out the window at the not so dark, I was reminded once again of how little deep darkness there is to be had out of doors in most of Britain, and how little they see of the expanse of the heavens at night. First you have the profound light pollution that’s difficult to avoid with over 60 million people living (and generating light) together on this little island. Then you have the extremely prevalent low cloud cover acting as an effective diffuse mirror for all that light, throwing much of it back down to any would be sky-gazer. So, for generations of Britons, the night sky is primarily an orange glow off the clouds, with the light pollution and humidity making little more than the major landmarks visible on even a “clear” night.

The day after I wrote the above, WeatherGirl’s mum mentioned that there was going to be a cool meteor shower over the next few days. Making my point nicely, it’s been thoroughly overcast, and we’ll have little chance of actually seeing any of it.

All in all, no comparison with the amazing night skies in and around Morris, especially when the winter cold has driven nearly every stray water molecule to ground.

How walkable is your neighborhood?

5th and Colorado
I recently discovered (sadly, I don’t remember how) WalkScore.com, where you can enter your (or any) address and have a “walkability” score calculated for your neighborhood. They use Google Maps to find out how far it is to a long list of important services and amenities (grocery stores, libraries, schools, coffee shops, and the like), and you get points based on how close you are. There are some issues (and they’re very up front about them) with using straight line distance as a proxy for walkability, but it’s not a bad approximation and a good start. There’s also no way they can take into account your preferences for things like schools and restaurants; you’d get points for living next door to a McDonald’s, for example, even if you’d prefer to go a little farther to the nifty local burrito joint.

Our house here in Morris scores a 54 out of a 100, which is probably about as good as you’ll get outside of a dense urban area (the Sears Tower in Chicago scores a whopping 94, for example). Personally, I think Morris is about as walkable/bikable a place as one is likely to ever find: Flat, reasonably compact, and with good roads and (mostly) sidewalks. It’s clear that Google Maps is confused about some of the businesses here in Morris as some of their distances are broken and they don’t know that we have a coffee shop a few blocks away (they list one nearly 25 miles distant!).

In total, it’s a cool idea, and I wish that it was available in the UK as we’re preparing to spend a year in Colchester without a car, and it would be nice to have a similar service while we look at houses and flats.

For amusement check out the scores of Bill Gates’s home and Shrub’s ranch in Crawford. Real environmentalists, these guys :-).
