One of science’s great odd couples — British minister Joseph Priestley and French tax administrator Antoine Lavoisier — together discover a fantastic new gas called oxygen, overturning the reigning theory of chemistry and triggering a worldwide search for new elements. Soon caught up in the hunt is science’s first great showman, a precocious British chemist named Humphry Davy, who dazzles London audiences with his lectures, introduces them to laughing gas and turns the battery into a powerful tool in the search for new elements.

Extra dimensions of space — the idea that we are immersed in hyperspace — may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still — but ultimately hit a dead end. Modern research has advanced the subject in ways he couldn’t have imagined. John Hockenberry joins Brian Greene, Lawrence Krauss, and other leading thinkers on a visual tour through wondrous spatial realms that may lie beyond the ones we experience.
