WORLD'S SMALLEST CALCULATOR
THE LONGEST LIST OF THE LONGEST
STUFF AT THE LONGEST DOMAIN NAME AT LONG LAST
What is the world's smallest calculator?
James Gimzewski at the IBM
laboratory in Zurich, Switzerland created the smallest calculator recently.
The calculator is smaller than one
millionth of a millimeter. It is a molecular abacus that has 10 molecules of
carbon 60 that is moved along a microscopic groove.
The molecules that create the
counters are molecules of carbon 60 or what is called “buckyballs”. The
buckyballs have 60 atoms of carbon which stick together to make a ball that has
the same surface structure of a soccer ball.
A tip of a scanning tunneling
microscope fondly referred to as the finger pushes the buckyballs around by
moving only one atom at a time.
The exact size of the world's
smallest calculator is 1 nanometer.
