A man runs to the doctor and says, "Doctor, you've got to help me. My wife thinks she's a chicken!"
The doctor asks, "How long has she had this condition?"
"Two years," says the man.
"Then why did it take you so long to come and see me?" asked the shrink.
The man shrugs his shoulders and replies, "We needed the eggs."
Gerd BinnigBorn 20 Jul 1947.German physicist who co-invented the scanning tunneling microscope with Heinrich Rohrer. They shared the 1986 Nobel Prize for Physics with Ernst Ruska, who designed the first electron microscope. This instrument is not a true microscope ( i.e. an instrument that gives a direct image of an object) since it is based on the principle that the structure of a surface can be studied using a stylus that scans the surface at a fixed distance from it. Vertical adjustment of the stylus is controlled by means of what is termed the tunnel effect - hence the name of the instrument. |
