We'll be back right after this break...

The Museum of Electrical Philosophy is grateful for the support of its principal sponsor, the Lux Corporation. If you aren't aware of them that's a measure of their effectiveness. And I wouldn't have mentioned them here if their presence had not recently been noted by respected security analyst Nick Selby at http://www.nickselby.com/yak. The only other thing I will say is that the organisation to which I refer is in no way related to Lux Products Corporation, manufacturers of thermostats and other fine equipment since 1912. Nor to any other company you may have heard of. That's the way they are.
