Saturday I missed a birthday party because I’m not on Facebook. So it goes.

My newest design on Shapeways is a model of the Lawson-Klein surface : a stereographic projection of

( cos(u)cos(2v), cos(u)sin(2v), sin(u)cos(v), sin(u)sin(v) )

I recently read the uncut Stranger in a Strange Land (having read the shorter version long long ago, probably before puberty). It contains the phrase “she’s as female as a cat in heat,” which also appears in the same author’s later Time Enough for Love; in each case it appears to be intended as a compliment.

Now that I know a bit about cat sexuality, I think: what, she’s ruled by her gonads even more than a 17yo boy, and miserable until she gets a rather unpleasant chore done?
