The new season of Century 21 Calling is here; still showing archival industrial films, corporate infomercials, TV reports and historical documentaries that shaped the imagination of tomorrow and hold them up to the light of the present.
This evening we will be screening the documentary Crystal Go To War from 1943. Created by the U.S. Army Signal Corps in 1943, it shows the processes that quartz crystals have to go through before they are ready to be inserted into radios and communication equipment.
