Editor Max Brockman introduces the work of some of today’s brightest and most innovative young scientists in this fascinating and exciting collection of writings that describe the very boundaries of our knowledge. Future Science features nineteen young scientists, most of whom are presenting their innovative work and ideas to a general audience for the first time. Featured in this collection are William McEwan (son of the novelist), a virologist, discussing his research into the biology of antiviral immunity; Naomi Eisenberger, a neuroscientist, wondering how social rejection affects us physically; Jon Kleinberg, a computer scientist, showing what massive datasets can teach us about society and ourselves; and Anthony Aguirre, a physicist, who gives readers a tantalizing glimpse of infinity.
