“When you think of the Hubs, think of large, mission-oriented research efforts such as the

Manhattan Project at Los Alamos or America’s great industrial laboratories in their heyday.great industrial laboratories in their heyday.

This type of research at AT&T’s Bell Laboratories gave us the transistor that powers

modern electronics.”
