Though strictly speaking it was the H bomb that could not have been made without an electronic computer, the Manhatten Project stimulated its development. Funding for computing was an integral part of the H bomb project from the start. See Turing’s Cathederal by George Dyson.
World War II’s Manhattan Project ushered in the Atomic Age. On the one hand, the project led to the development of the first nuclear bombs, but it also produced a wealth of new scientific knowledge from which mankind is still reaping the rewards today. Hank Green looks back at that massive project and its enormous consequences in this edition of the SciShow.
