Dentist

A guy and a girl meet at a bar. They get along so well that they decide to go to the girl's place.
A few drinks later, the guy takes off his shirt and then washes his hands.
He then takes of his trousers and washes his hands again.
The girl has been watching him and says, "You must be a dentist."
The guy, surprised, says "Yes! How did you figure that out?"
"Easy," she replied, "you keep washing your hands."

Element 109

In 1982, an atom of a new element was made. It has been given the proposed name of Meitnerium, symbol Mt. Physicists at the Heavy Ion Research Laboratory, Darmstadt, West Germany made and identified element 109 by bombing a target of Bi-209 with accelerated nuclei of Fe-58. After a week of target bombardment a single fused nucleus was produced. The combined energy of two nuclei had to be sufficiently high so that the repulsive forces between the nuclei could be overcome. The team confirmed the existence of element 109 by four independent measurements. The nucleus started to decay 5 ms after striking the detector. This experiment demonstrated the feasibility of using fusion techniques as a method of making new, heavy nuclei.
