This one never gets old - The New CEO

A company, feeling it was time for a shakeup, hired a new CEO.
The new boss was determined to rid the company of all slackers.
On a tour of the facilities, the CEO noticed a guy leaning against a wall and idly picking his teeth.
The room was full of workers and he wanted to let them know that he meant business.
He asked the guy, “How much money do you make a week?”
A little surprised, the young man looked at him and said, “I make $400 a week. Why?”
The CEO said,”Wait right here.”
He walked back to his office, came back in two minutes, and handed the guy $1,600 in cash and said, “Here’s four weeks’ pay.
Now GET OUT and don’t come back.”
Feeling pretty good about himself the CEO looked around the room and asked,
“Does anyone want to tell me what that goof-ball did here?”
From across the room a voice said,
“Sure – he was the Pizza delivery guy from Domino’s and was just waiting to collect the money!”

Pulsar discovery

In 1967, the first pulsating radio source (pulsar) was detected by an alert graduate student, Jocelyn Bell, then working under the direction of Prof. Anthony Hewish at the Mullard Radio Astronomy Observatory, Cambridge, England. A special radio telescope was used, with 2,048 antennae arrayed across 4.4 acres. By 13 Nov 1998, one thousand had been found. The pulsing of the radiation has clock-like precision , up to 1,000 times per second. A pulsar is believed to be a neutron star with exceedingly rapid spin. Rotational periods range from 1.57 milliseconds to 5.1 sec. Pulsars prompted studies of quantum-degenerate fluids, relativistic gravity and interstellar magnetic fields. Similar behaviour of a star flashing in the optical spectrum was detected on 18 Jan 1968.Optical pulsars remain very rare.«
