For the September edition, we explain how mathematics is an indispensable tool for space exploration, how honeybees are masters of geometry, and about the unbelievable uniqueness of a shuffled deck of cards.

The ear phonautograph was a macabre instrument. It was built by Alexander Graham Bell and Clarence J. Blake in 1874, and used a surgically-removed human ear—a skull fragment, ear canal, ear drum, and ossicle bones—to visually “write” sound waves.
