The CEO was scheduled to speak...

The CEO was scheduled to speak at an important convention, so he asked one of his employees to write him a punchy, 20-minute speech.
When the CEO returned from the big event, he was furious. "What's the idea of writing me an hour-long speech?" he demanded to know. "Half the audience walked out before I finished."
The employee was baffled. "I wrote you a 20-minute speech," he replied. "I also gave you the two extra copies you asked for."

Oldest eclipse record

In 1375 BC, the oldest recorded eclipse occurred, according to one plausible interpretation of a date inscribed on a clay tablet retrieved from the ancient city of Ugarit, Syria (as it is now). This date is one of two plausible dates usually cited from the record, though 5 Mar 1223 BC is the more favoured date by most recent authors on the subject. Certainly by the 8th century BC, the Babylonians were keeping a systematic record of solar eclipses, and possibly by this time they may have been able to apply numerological rules to make fairly accurate predictions of the occurrence of solar eclipses. The first total solar eclipse reliably recorded by the Chinese occurred on 4 Jun 180 BC.«[Image: a modern photograph of a total solar eclipse.]
