Mo Mandel: Hippie Parents

Grew up with those hippie parents. Mom was always smoking weed around the house. Its not cool. If youre a parent, dont smoke weed in front of your kids, because it ruins weed for your kids, and thats selfish. I see my Mom rolling joints -- very confusing. First time someone offered me a joint in high school, I was like, Im not going through menopause. Why would I want that? My temperatures fine, and Im very fertile.

First electron tube

In 1904, the first electron tube, a diode thermionic valve, was invented by John Ambrose Fleming. The valve consists of a carbon or tungsten filament lamp, to which is added a metal plate (insulated from the filament), and a connecting wire brought through the glass wall of the bulb to a third terminal outside. When battery current is applied to the filament making it incandescent, the space between the filament and the insulated plate will be found to conduct elecrons in only one direction. That means if the valve is connected in a circuit in with an oscillating current, its one-way conductivity will convert the oscillating current into a unidirectional current capable of actuating a telephone receiver. He notified Marconi in a 30 Nov 1904 letter.
