Back by popular demand, Nobel prize-winning physicist William Phillips takes us on a voyage to the lowest temperatures ever recorded. What is an atomic clock and why do they keep better time when they’re cold? And just what is the relationship between speed, temperature and relativity? Phillips shows us with jaw-dropping experiments what happens when ordinary objects are taken to the edge of absolute zero....[Read more]
