How do the tiny, crowded, constantly moving molecules inside of cells come together to form functional structures such as organelles? While many of the organelles we are familiar with, such as the nucleus and the Golgi apparatus, are membrane bound, Cliff Brangwynne explores the physics and biology behind the fascinating and important cellular structures that are not surrounded by a membrane.
