By now Wolfram|Alpha might already be old news, but just in case you haven’t heard about it, you should really check it out…
Wolfram|Alpha is set-up to look like a Search Engine similar to Google, but it is actually a “computation machine.”
This resource is a good tool for finding statistics, socio-economic data, information on a date, figuring out equations, and has data on specific locations.
You’ll see on their Examples by Topic page that Wolfram|Alpha could be useful for the following Subjects — Math, Physics, Chemistry, Astronomy, Education, Sociology, Criminal Justice, Engineering, Geography, and a lot more.
Just to get a feel for it, I suggest plugging in your Birthday to see what you get, then try doing a comparison, for example: Scranton, PA vs. Philadelphia, PA.
I’m sure you’ll at least find it to be interesting. Those of you who work with numbers, facts, and data might find this “computation machine” to be downright awesome.
