Nicolaus Copernicus (1473-1543) and
Galileo Galilei (1564-1642)

Copernicus stayed here
while in Bologna!
This year (2009) is very important in both physics and astronomy. Four hundred years ago, Galileo Galilei improved the magnifying power of the existing telescopes by ten times, and started looking at the the sky. He did this using the glass technology available from the Murano Island in Venice. Even these days, Murano is well known for its crystal products.
