I will have to check this out. Thanks for discussing it!

A colleague of mine, S. James Gates (theoretical physicist), uses something he calls "The Einstein Hypotenuse" to engage an audience with some skill in high school trigonometry in understanding how certain things, like the speed of light, are left invariant even as space and time change with relative motion. It sounds very similar to what Egan uses.
