86349266_e531245ee9 Author of This Will Change Everything and Edge Foundation president John Brockman invited Edge community members, who span the range of intellectual pursuit, to react to the ash cloud from Iceland's Eyjafjallajökull volcano and to tell him, in 250 words or less, something he "didn't already know and wasn't going to read in the newspapers."
