Speaking of map projections

Wolfram|Alpha is pretty amazing, I think. My brain doesn't have enough oomph to really play with it much, but I've been able to use it on occasion.

Now they have this new thing going, Wolfram|Alpha Widgets. Supposedly you can use their tools to create useful little widgets to put on a blog or web page. Supposedly it's simple. Maybe a dummy like me can do it!

I might try this out. If I can do it, I'll make a widget to do some engineering computations at work, such as converting transmission line impedances from a 50 MVA / 345 kV base to something else like 100 MVA / 525 kV. Maybe a widget to decypher the status bits in a synchrophasor stream or something.

It seems this thing might be very useful (assuming I can muster the mental steam to do it, which isn't a sure thing).

But speaking of map projections, someone called Jessica Paris made a widget to see a map of the globe in various different projections. They say it's as simple as copying the embed code into the HTML view of the post I'm typing. Let's see if I can stick it in here:

Hey, it worked!

As for the angelic projection at the bottom of my last post, I guess it looks like an equirectangular projection, but I'm not sure.
