A dietitian was once addressing a large audience in Chicago:

"The material we put into our stomachs is enough to have killed most of us sitting here, years ago. Red meat is awful. Soft drinks erode your stomach lining. Chinese food is loaded with MSG. Vegetables can be disastrous, and none of us realizes the long-term harm caused by the germs in our drinking water.

"But there is one thing that is the most dangerous of all and we all have eaten or will eat it. Can anyone here tell me what food it is that causes the most grief and suffering for years after eating it?"

A 75-year-old man in the front row stood up and said, "Wedding cake."

First Audion tube

In 1906, the first triode was ordered by Lee de Forest who instructed the New York automobile lamp maker, H. W. Candless, to make a glass bulb containing a "grid" wire between a filament and an electrode plate. These specifications extended the Fleming two-element diode valve design previously published in the Proceedings of the Royal Society. The third element - the grid wire - regulated the flow of electrons between the filament and the anode plate, producing an amplification of the variations in a signal voltage applied to the grid. De Forest named his invention the "Audion." Within a few years (1913-1917) he was able to profit from his patents that he sold to AT&T for a total of $390,000.«[Image: A de Forest Audion tube, circa 1912.]
