Nicolas Steno

To salute Nicolas Steno, Google has dug up an especially beautiful “Doodle.”
Where the company’s homepage logo typically sits, the six letters of ”Google” become brightly colored rock layers that mark not just time, but specifically the 374th anniversary of Steno’s birth.
The Danish natural scientist — who was born “Niels Stensen” on Jan. 11, 1638 — is widely considered the father of geology.
