The authors wish to thank Moira Gresham, a member of the Department of Physics at Whitman College, and E. Sonny Elizondo, a member of the Department of Philosophy at UC Santa Barbara, for their thoughtful feedback on this paper.

** Tim Doyle** is originally from western Washington, and completed undergraduate work at Reed College and graduate work at UCLA, primarily in philosophy, but with lots of math thrown in for good measure. His research interests include, but are definitely not limited to ancient philosophy, philosophy of mathematics and logic, and early analytic philosophy. When he's not talking to students or buried in books, he moonlights as a winemaker.

** Lauren Kutler** is a Math for America Teaching Fellow currently teaching algebra and geometry at Malden High School (near Boston, MA). She double majored in mathematics and philosophy at Whitman College and then completed a Master of Arts in Teaching at Boston University. Lauren also enjoys exploring the outdoors, traveling, and cooking with a lot of vegetables.

** Robin Miller** grew up in Corvallis, Oregon, and attended Whitman College, where she double majored in Mathematics and Economics and was an active member of the college orchestra and choir. After working as a business analyst for two years, she decided to go back to school and study to be a web developer. She is now living in Portland, Oregon and working as a software engineer for a local tech startup. In her spare time, she enjoys cribbage, strategy board games, cooking, and spending time with her family.

** Albert Schueller** is originally from Philadelphia, PA. He majored in mathematics at Penn State University ('90) and earned a PhD in mathematics at the University of Kentucky ('96) in inverse eigenvalue problems. He has always enjoyed computing and programming. He installed Linux for the first time in 1994 using 120 1.44Mb floppy disks. He is an avid proponent of open-source software and open-source textbooks.
