Happy 400th BDay to Galileo's Telescope!

Google is celebrating the 400th anniversary of Galileo’s telescope. Its amazing how much his innovation has changed the world and how we understand it. From National Geographic’s article Galileo’s Telescope at 400:

Just over 400 years ago, Galileo–then chair of mathematics at Italy’s University of Padua–got word that Dutch glass makers had invented a device that allowed viewers to see very distant objects as if they were nearby.

The mathematician soon acquired a Dutch instrument, and on August 25, 1609, he presented an improved, more powerful telescope of his own design to the senate of the city-state of Venice. The government officials were so impressed with Galileo’s telescope that they rewarded the professor with a higher salary and tenure for life at his university.
