Based largely on Tom Shachtman’s acclaimed book, Absolute Zero and the Conquest of Cold, the documentaries will explore key concepts, significant individuals and events in the field of low-temperature physics and the enormous impact that the mastery of cold has had on society through such technologies as air conditioning, refrigeration and liquefied gases.
