What happens when particles lose their individuality and merge into a single quantum being? This is the mystery of the Bose–Einstein condensate — a state of matter predicted by Einstein and Bose a century ago, first realized with ultracold atoms in the 1990s, and later extended to photons, exciton–polaritons, and other exotic systems. In this book, Boris Kriger guides the listener through the history of this extraordinary discovery — from a letter written in Calcutta to Einstein, to the Nobel-winning experiments that cooled atoms to the edge of absolute zero.

In May 1862, Robert Smalls, a slave and ship’s pilot in Charleston, South Carolina, crafts a daring plan to steal the steamship Planter and deliver it, along with, the crew and their families to the Union blockade. After risking his life to escape slavery, Robert faces an even more difficult challenge: convincing Abraham Lincoln to enlist black troops.
