The sounds of science

Outside the Department of Earth Sciences at the University of Oxford, there are several gigantic, almost-building height tanks of liquid nitrogen behind a fence, encrusted with ice and with vapour hissing out from the pipes at the bottom.

The sounds of hissing liquid nitrogen vapours mix with the industrial drones of other nearby scientific machinery and air conditioning devices coming from science labs, a sonic reminder of all the fantastic research taking place behind closed doors in these advanced university research facilities.
