Name: Amedeo Avogadro                                                                 
Born: 1776                                                                             
Amedeo Avogadro was born in Turin August 9th 1776 to a                                 
noble ancient family of Piedmont , Italy .                                             
He graduated in ecclesiastical law  at the                                             
early age of 20 and began to practice. Soon thereafter he dedicated                   
himself to the study of physics  and mathematics, and in 1809                         
started teaching them at a /liceo/ (high school) in Vercelli                           
(where his family had some properties).                                               
In 1811, he published an article with the title "Essay on                             
Determining the Relative Masses of the Elementary Molecules of Bodies",               
which contains the famous Avogadro's hypothesis.                                       
In 1820 he became a professor of physics at the University of Turin                   
Avogadro held public posts in statistics, meteorology, and weights and                 
measures (he introduced decimal metric system in Piedmont) and was a                   
member of the Royal Superior Council on Public Instruction.                           
In honour of Avogadro's contributions to the theory of molarity                       
and molecular weights, the number of molecules in one                                 
mole  was renamed /Avogadro's number/, N_A . It is approximately 6.0221415 × 10^23 .
