“Three-terminal thermal analogies to electrical transistors have been proposed for use in thermal amplification, thermal switching, or thermal logic, but have not yet been demonstrated experimentally.

Probably the most important invention of the 2oth Century was the transistor. The first point contact transistor shown below was made at Bell Laboratories. The workbench of John Bardeen and Walter ...

Nullator, norator, and nullers all started out as theoretical circuits. A nuller is the result of the combination of a nullator and a norator, which forms a network element with a transmission matrix ...
