Niels Bohr and Albert Einstein, 1925.

I have always been fascinated by the photo
posted here. It shows the physicists Niels
Bohr and Albert Einstein side-by-side, lost
in thought. Bohr's head is bent down, his
eyes are deeply lowered, his finger across
his lip. Einstein's gaze goes outward and
upward, his hand placed only abstractedly
for emphasis.

Bohr was the great physicist of the atom,
of quantum theory and the most subtle and
smallest processes of the universe.

Einstein's vision was cosmological, ranging
across galaxies.

And yet, both part of the same exact thing.

Inward and Outward.

Microcosm and Macrocosm.
