In the twenty-eighth episode of the second season of the “Saturdays at Seven” conversation series, Todd Ream talks with Francis Su, the Benediktsson-Karwa Professor of Mathematics at Harvey Mudd College. Su opens by discussing what motivates mathematicians and how the strange, uncanny, wonderful, and unexpected encounters are often the ones that excite them the most. In Su’s opinion, mathematics is defined as a habit of mind that is constantly undergoing formation. When such a process is well-oriented, strange, uncanny, wonderful, and unexpected encounters become sources of joy, inviting new ways to see and experience the world. Su shares that while his own formation as a mathematician eventually took on such an orientation, that process proved challenging, demanding deep reflection upon what he was uniquely called to contribute and the ways mathematics could serve as a means for such contributions. Along those very lines, Su contends that mathematics education often asks too little of students, demanding that they merely perform as human calculators, not as individuals in pursuit of truth to which mathematics is uniquely positioned to contribute. Su closes by sharing how mathematicians and the habits of mind they exhibit can be of greater service to colleagues in other disciplines, how scholars in other disciplines can be of greater service to mathematicians, and how both groups can work together to contribute to the mission of the Church.
