Synthetic diamonds

In 1955, the General Electric Company announced their successful synthesis of 1/16" diamonds using the first process that was reproducible. The GE Super Pressure Project research team had worked since 1951 to create a special pressure vessel to subject carbon compounds to pressures of up to 1,500,000 lb/sq.in. at temperatures of up to 5,000 deg F. They created the first diamonds on 16 Dec 1954, beginning GE's man-made industrial diamond business. Manufactured diamonds are used as abrasives in masonry saws, mining drill bits, polishing machinery, and cutting tools. (On 16 Feb 1953, a Swedish scientist was the the first to create diamonds in an experiment that was not repeated, and held secret prior to GE's announcement.)«[Image: Watson-Stillman press used to make GE's first diamonds]

Please stand up

One day a college professor of Psychology was greeting his new college class. He stood up in front of the class and said, "Would everyone who thinks he or she is stupid please stand up?"

After a minute or so of silence, a young man stood up.

"Well, good morning. So, you actually think you're a moron?" the professor asked.

The kid replied, "No sir, I just didn't want to see you standing there all by yourself."
