Issues

While the problems underlying message communication have largely been described in mathematical terms, some outstanding questions must be answered before the theory can be put to more practical use.

Physical research in Switzerland, while handicapped to some extent by the same financial problems that beset science in other European countries, is nevertheless being pressed vigorously in a number of directions. The following article reviews the activities of the main Swiss research centers.
