http://en.wikipedia.org/wiki/Point-contact_transistor
A small positive current applied to one of the two contacts had an influence on the current which flowed between the other contact and the base upon which the block of germanium was mounted. In fact, a small change in the first contact current, caused a greater change in the second contact current, thus it was an amplifier. The first contact is the "emitter" and the second contact is the "collector". Today the terminology for the three terminals of a bipolar transistor are base, emitter and collector. The low current input terminal into the Point Contact Transistor is the Emitter, while the output high current terminals are the Base and Collector.
Note:
This differs from the later type of junction transistor invented in 1951 that operates as modern transistors do, with the low current input terminal as the Base and the two high current output terminals are the Emitter and Collector.

Our script runs on boot if we make script:
