As a kid, one of my favorite books was Heaven & earth: Unseen by the naked eye by Katherine Roucoux. It showed - chapter by chapter - intricate landscapes of increasing scale and distance, captured by microscopes, x-rays, satellites and telescopes. Each photograph was accompanied by an extended caption that explained it in detail, offering a dose of scientific information connecting it to the human scale. I absolutely loved it because it made obvious this mysterious correlation that seemed to occur between different natural systems. Regardless of whether you were looking at a human eye, a city, or the andromeda galaxy, it was impossible not to see the similarities. To us urbanists, this opens a discussion for a more holistic perspective on urban planning and design, one that is inspired by natural systems. To guide us through this discussion I have with me Maria Augusta do Amaral Kroetz and Ocean Jangda, two graduate urban technologists from IAAC’s Master in City & Technology along with 2 very special guests, IAAC's Head of Studies, Dr. Mathilde Marengo and AIT's City Intelligence Lab Director, Angelos Chronis.
