...senior in question was Richard Friedberg of Manhattan, a modest 20-year-old who plays the piano, sings in the glee club, majors in mathematics. Last week not only the Globe but mathematicians across the U.S. were buzzing about what has turned out to be a major mathematical achievement...
...Friedberg's feat was to solve a problem, first posed by the late Emil Post of New York's City College in 1944, that has been baffling mathematicians ever since. The problem: Does each non-recursive, recursively enumerable set have the property that every recursively enumerable set is recursive in it? Post himself thought not, but it was not until young Friedberg came along that anyone had the proof...
Andrew M. Gleason, associate professor of Mathematics, reported that "everybody in the Mathematics department has been very pleased with Friedberg's success in this problem...
...Friedberg, a pre-medical student, had never read any books on mathematical logic before last August. The solution grew out of his work on related questions in the general field of mathematical logic...
...making positive what had been previously hypothetical, Friedberg's solution provides a basis for further investigation in the undecidability of axiomatic theories," Willard Van Orman Quine, professor of Philosophy, explained...
