Book excerpt: The Massachusetts Institute of Technology's Laboratory for Computer Science (LCS) hasbeen responsible for some of the most significant technological achievements of the past fewdecades. Much of the hardware and software driving the information revolution has been, andcontinues to be, created at LCS. Anyone who sends and receives email, communicates with colleaguesthrough a LAN, surfs the Web, or makes decisions using a spreadsheet is benefiting from thecreativity of LCS members.LCS is an interdepartmental laboratory that brings together faculty,researchers, and students in a broad program of study, research, and experimentation.
