I have recently become interested in this subject after reading a book by David A. King
Qibla, in Arabic, asks for the geographic direction to the “cube”, or Ka’ba, in Mecca
This is a fairly technical talk on a subject of recent interest. Map projections, are made somewhat obsolete by computer technology. For example, computing on the sphere or ellipsoid is now as easy as on a projection, and one computer atlas uses pictures of a globe that can be rotated to see any part. Nevertheless I am going to talk about a particular kind of map projection.
