Maps in Space
In the last year or two I've become more and more interested in subjects that brush up against celestial mechanics...the movements of the planets, the math behind sundials, the intricacies of orreries, the libration of the Moon, that kind of thing.
One of the things that I find most fascinating is how we humans came up with mapping and navigation systems to use in space...how we decided where to place the Prime Meridian on Mars, how we can accurately describe the orbits of satellites, etc.
I was delighted to be able to give a talk on this subject at this Spring's Where 2.0 Conference in San Jose.
