Fact of the day: It was on this day in 1876 that Alexander Graham Bell sent the famous first words over his telephone system saying: "Mr Watson, come here. I want you." Also on this day, but in 1891 an undertaker by the name of Almon Strowger patented a device later known as the Stowger switch that led to the automation of telephone circuit switching.

Quote: A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools. Douglas Adams

Point to ponder: The light emitting diode effect was first noticed in 1907 by HJ Round, while experimenting on cat\'s whisker detectors. He published his results in the Electrical Review. However it took until the 1960s before LEDs were commercially available.
