摘要:In the1960s I got a Ph.D. in mathematics and worked for about 10 years in the Mathematics Department of a large University. Thereafter I left mathematics to work in cognition, philosophy of science, religion and spirituality, and to do qualitative research dealing with individuals’ lives (all this time at the College of Education here at the University of Illinois). However, mathematics has always been with me. Since antiquity there has been a mystery about mathematics—what mathematics really is, what mathematical entities are, how mathematics relates to the universe and existence, as well as why people devote their lives to this kind of activity. And there is another mystery. When I was in the Math Department it was obvious that many of my colleagues were in some way inspired by mathematics, and that working in mathematics and teaching it brought them some measure of fulfillment. So as part of my work in the College of Education I started a far-ranging interview project to explore undergraduate and advanced graduate students’ subjective experience of mathematics in their high school and undergraduate years. The book above is based on this project.
