The Net Advance of Physics RETRO:
STEAM TECHNOLOGY in the Long Nineteenth Century, 1790-1920


Please note: Most material in Net Advance Retro antedates 1920. It may be obsolete or incorrect.

Experimental projects described in old scientific papers are frequently unsafe. This is especially true of projects described as "suitable for amateurs" or "suitable for children"; such projects are rarely suitable for children or amateurs in the Twenty-first Century.
