As previously reported, Google was running a Google doodle on its home pages around the world as it became February 19th. Now it's February 19th here in the U.S. and other countries on this side of the globe, and the doodle has come along with the date change. It celebrates Nicolaus Copernicus, the famous mathematician and astronomer from Poland who, during the Renaissance, came up with the heliocentric model, which placed the sun (as opposed to the Earth) at the center of the universe.
Here's a video showing the doodle's animation, courtesy of Simon Rüger:
If you click the doodle, you'll get to search results for "Nicolaus Copernicus". Of course, Google's Knowledge Graph results are on display, as they often are for the subjects of Google's doodles these days. Here's what the panel for Copernicus looks like:
Note that people who search for Copernicus also search for Galileo Galilei, Johannes Kepler, Isaac Newton, and Ptolemy.
Yesterday, Google ran a doodle celebrating the 812th birthday of Nasir al-Din al-Tusi in the following countries: Bahrain, Afghanistan, Saudi Arabia, Libya, Algeria, United Arab Emirates, Egypt, Palestinian Territories, Lebanon, Qatar, Morocco, Jordan, Tunisia, Oman, Iraq and Kuwait.
