1x2 - Absolute Zero

Documentary charting rival attempts to reach absolute zero, the ultimate limit of cold, by scientists in London and Leiden. A second race unfolded 100 years later, towards the end of the 20th century, as scientists attempted to produce a Bose Einstein Condensate, a new state of matter predicted by Einstein.With the winner of each scientific race going on to win the Nobel Prize for their work, ultra-cold research has proved to be one of the most competitive fields of modern science.
