Jumpin' Cats! Take a look at today's Google Doodle thingy...it's Nick Steno's 374th B-Day, and they've got a cartoon in honor of it! Neat-o!
Steno has, of course, been mythologized as one of the fabled "father's o' geology", most often remembered for his "three Laws": Original Horizontality, Lateral Continuity, and of course Superposition. Pretty nice exposure!
EDIT: I guess it is a bit layer-cakey...maybe for Wheeler's Birthday, they'll have an animated one that blows it apart and constructs a Wheeler Diagram, to show the difference between time-as-rock and time-as-surfaces.
