I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in the classical Greek synthetic form and in the more modern analytical form.

comment Increase 3D Graph thickness for 3D printing in Mathematica?
I'm confused by your terminology. What do mean by "width" and "thickness"? I have no idea what dimension "width" refers to, and as for "thickness", a surface it infinitesimally thin by definition.

Won't work. The stream name has "~" expanded to the full path.
