IN HARVARD’S HIGH-TECH CLEANROOM, APPLIED PHYSICISTS PRODUCE
VIVID OPTICAL EFFECTS—ON PAPER
In a sub-basement deep below the Laboratory for Integrated
Science and Engineering at Harvard University, Mikhail Kats gets dressed. Mesh
shoe covers, a face mask, a hair net, a pale gray jumpsuit, knee-high fabric
boots, vinyl gloves, safety goggles, and a hood with clasps at the collar—these
are not to protect him, Kats explains, but to protect the delicate equipment
and materials inside the cleanroom.
