for improvement. Share owner relations is far from an exact scienceand the future may hold more refinements than therecent past, he observes. For example, our studiesshow that the great bulk of our owners feel they aregetting about the right amount and type of informa-tion they need. But some say we give them too much.And others want more. The day may come, however,when we can isolate each group and tailor separateprograms to their specific needs. Whatever changes are made, one thing will prob-ably remain the same. Share owners will place a par-ticularly high value on direct contacts with the man-agers of the business, whether it be in the form of aletter, a telephone call, or a personal visit.

THIS MAN IS NOT SMILING The headline youve just read is informationless.It tells you nothing you havent already learned fromlooking at the picture. If someone tells you your ovi^n name, he again trans-mits no information: you already know it. He doesntresolve any uncertainty for you. This idea—that whatever resolves uncertainty isinformation—was used by Dr. Claude E. Shannonduring his years at Bell Telephone Laboratories todefine and measure information for the first time ina way that was usable to scientists. Starting fromsuch basic concepts, Shannon built a theory which hasmany applications to problems in communication andin other fields. In 1948, he published his classic paper,A Mathematical Theory of Communication. Before this there was no universal way of measur-ing the complexities of messages or the capabilities of circuits to transmit them. Shannon gave us a mathe-matical way of making such measurements in terms ofsimple yes-or-no choices—conveniently represented bybinar
