1947 - Bardeen and Brattain
Demonstrate the Transistor to Bell Labs Supervisors
John Bardeen and Walter Brattain demonstrate
the point-contact transistor, made from strips of gold foil on a plastic
triangle, pushed down into contact with a slab of germanium. To measure the
amplification they hooked up a microphone to one end of the device and a loudspeaker
to the other. One by one, the men picked up the microphone and whispered,
“Hello.” The loudspeaker at the other end of the circuit shouted, “HELLO!”
Although William Shockley had played a smaller role in the invention of the
point-contact transistor, he was inspired by its promise, and devoted his time
and efforts for more than a month to improving upon the device. By early 1948
he had devised the junction transistor, a device that shaped the design of
nearly all transistors to follow.
1968 – First Men to Orbit the
Moon
Astronauts Frank Borman, James A. Lovell,
and William Anders become the first men to orbit the Moon. Flying in Apollo 8,
the men perform 10 total lunar orbits and test many of the procedures that will
be used in future lunar missions. Additionally, the men were the first to see
Earth as a whole planet, and the first to directly see of the Moon. On Christmas
Eve, the crew made a television broadcast from which they read the first 10
verses from the Book of Genesis. It was the most watched television program
ever at the time.
1986 – Dick Rutan and Jeena Yeager touched
down at Edwards Air Force Base in the experimental airplane Voyager, completing
the first non-stop, round-the-world flight without refueling.
2008 – Santa Claus via Google
Earth
Santa Claus is spotted on Google Earth. Of course
the story of St. Nicholas is an interesting one that doesn’t really involve
religion. But now we know where he resides, thanks to Google!
