Why is spherical trigonometry a lost art? What is "Heavenly Mathematics" about and what background is needed to learn the material? To you spherical trigonometry is an exquisite branch of mathematics. How so? What calculations could be performed accurately a few hundred years ago, or earlier? What techniques are used to determine the size of the earth, or the distance to the moon? What is the most elegant theorem of spherical trigonometry? How is spherical trigonometry important today in the context of modern technology? Is there a next book? What advice would you give to a parent whose child was struggling with math?

Richard Rusczyk is the founder of the Art of Problem Solving, the premier community for high-performing middle and high school math students in the English-speaking world. I've always been intrigued with the world of math competitions and with what it takes to excel in them. I picked Richard's brain for an hour about competitions and about his company.

Sue VanHattum is very excited about creative ways to look at math. She has compiled and written a number of the chapters in a new book, Playing With Math, which is being produced in a community supported publishing (i.e. crowd funding) model. Listen to Sue's enthusiasm, learn about the book, then reserve your copy at https://www.incited.org/en/projects/4992-Playing-With-Math---the-Book

Lou DiGioia is the executive director of MATHCOUNTS, the largest nonprofit organization dedicated to extracurricular middle school mathematics. Lou and I discuss a number of MATHCOUNTS programs, including the recent National Competition, the National Math Club, and the Math Video Challenge. We discuss who the programs serve, and so much more. And, we do this all with a ton of infectious enthusiasm.

Al Cuoco has taught high school students, trained teachers, and developed curriculum that is really making a difference in math education. He and Joseph Rotman have published a book with the MAA, "Learning Modern Algebra From Early Attempts to Prove Fermat's Last Theorem." Al and I discuss a number of the principles and habits of mathematical thinking that are developed in the book.

David Reimer, author of "Count Like an Egyptian" and I discuss Egyptian computation methods, how kids can learn to do multiplication and division without shedding a tear or memorizing tables, how computers and Egyptians both use the same approach to multiplication, why brilliant mathematicians make better teachers and professors, and much more.
