Johnson Hall Deep Freeze

Blankets of snow look good around St. Lawrence University’s Johnson Hall of Science.

Lasers

The hours I spend in the physics and chemistry labs of St. Lawrence University make me a bit inured to the optical shenanigans occurring when we take Raman spectra of the materials my students synthesize. Still, the effect is pretty fantastic. The grainy pattern of the laser on surfaces around lab is fantastic, but the fluorescence ink on the post-it note in the foreground fluorescing aggressively is pretty cool, too.

That violet-blue light in the background of the shot above is the 405 nm laser we use to initiate photochemical processes. The beam is poorly detected by the camera’s sensor, but the slightest hint of it is visible in the upper third of the image below.

Cartesian Grid of Building 66

The utilitarian, earthquake-resistant architecture of Berkeley Lab amid the verdant hills of the East Bay seems like a science-fictional setting—a location that can’t possible exist—in contrast to San Francisco in the distance.

Winter On Campus

St. Lawrence University’s campus is quiet for the moment; athletes have returned early from break but pretty much everyone else is still on winter vacation. The snow adds an extra layer of dampening.

When they return,  the school will once again take on its weird ski lodge vibe.
