Today, Google is celebrating the 374th birthday of the founder of modern geology, Nicolas Steno with a special logo.
As you can see, the logo looks like exploration of the ocean to the earth and its inhabitants. It is a great symbolism of Nicolas Steno work.
Nicolas Steno was born on January 11, 1638 in Denmark and died on December 5, 1686 in Schwerin, Duchy of Mecklenburg-Schwerin.
He had a very interesting life, which you can read about on Wikipedia.
I personally like the Google logo, aka Doodle, very much. Kudos to the Google Doodle designer on this.
