LIFE IN SCIENCE: Sounds of Atoms
Paul S. Weiss and Stephan J. Stranick
Description for one of the samples:
"Scanning tunneling microscope image and associated audio signature. The tunneling current is fed into one channel of a stereo, and the feedback loop voltage controlling the tip-sample separation is turned into a tone (carrier frequency 165 Hz) and fed into the other, while a self-assembled monolayer of alkanethiols on Au{111} is imaged with molecular resolution at 4 K in extreme high vacuum. The wobbling tone is the feedback loop. Other sounds are indicators of the correct operation and the levels of noise in the system. Video file credit: Patrick Han, Adam Kurland, and Paul Weiss, the Pennsylvania State University." via dr ben goldacre who notes the samples are "from their new album 'Weiss and Stranick 322 (5899): 190 Data Supplement - Supporting Online Material -- Science'"
