In this episode, Ms. Angie and Ms. Alisha introduce “memory palaces” and the human talent for spatial memory, as elucidated by Sherlock Holmes and Simonides, the ancient Greek poet who left the banquet only to have the building crash down behind him. We also demonstrate how to perform this feat to increase your own memory powers (by memorizing the middle school camp packing list), and explore the correlation between memory and intelligence.
