Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment What is invisible to x-rays?
@KevinFegan: no. That's because the band gap in glass lies in the uv. See this related question for more or search this site for something like glass transparent

comment Magnet insulation and Permanent magnets
@user7063: There is no such thing as a perfect insulator, either magnetic or electrical, but superconductors come pretty close to perfect magnetic insulators (though a superconductor will cease to be superconducting if you make the magnetic field too strong).
