The first monolithic integrated circuit, about the size of a finger tip, was documented and developed at Texas Instruments by Jack Kilby in 1958. The IC was a chip of a single Ge crystal containing one transistor, one capacitor, and one resistor.The first monolithic integrated circuit, about the size of a finger tip, was documented and developed at Texas Instruments by Jack Kilby in 1958.

Congrats to the Chinese space program for their successful manned orbiting mission. Maybe some day they'll follow us here, too (Apollo 11, July, 1969).Congrats to the Chinese space program for their successful manned orbiting mission.

The Wilkinson Microwave Anisotropy Probe (WMAP) team has made the first detailed full-sky map of the oldest light in the universe. It is a "baby picture" of the universe. Colors indicate "warmer" (red) and "cooler" (blue) spots. The oval shape is a projection to display the whole sky; similar to the way the globe of the earth can be projected as an oval. This image has 45 times more resolution than the previous map (COBE).The Wilkinson Microwave Anisotropy Probe (WMAP) team has made the first detailed full-sky map of the oldest light in the universe.
