In his seminal work from 1945, How to Solve It, George Polya introduced principles of mathematical problem solving that are widely applicable to problems in science and engineering. This yearlong class focuses on building a powerful and portable problemsolving and modeling tool kit while bridging the divide between mathematics and science courses. The second semester will be organized around projects in areas of student interest. Both Math ESPA and Math ESPB must be taken in the same academic year to receive credit.

Multivariable real analysis and calculus: topology of Euclidean space, limits, continuity, and differentiation in n dimensions, inverse, and implicit functions, manifolds, Lagrange multipliers, path integrals, div, grad, and curl. Emphasis on topics that are applicable to fields such as physics, economics, and computer science, but students are also expected to learn how to prove key results.
 Course Notes:
 Students are expected to watch videos of the lectures from Fall 2015 before attending class. Weekly twohour classes will consist of a onehour seminar in which students present key definitions and proofs and a onehour activitybased session in which students work in small groups to solve problems. Students are expected to continue in either Mathematics 23b (recommended for students who are thinking of concentrating in mathematics, the physical sciences, or engineering) or Mathematics 23c (recommended for students who are not sure of their concentration, or who are thinking about a concentration in the social sciences, economics, computer science, life sciences or data science). Either alternative will provide a solid foundation for a concentration in mathematics or any field that uses mathematics.
 Class Notes:
 This section assumes a background in sequences and series, covers applications of linear algebra and calculus to data analysis, teaches the R scripting language, has required programming assignments in R, and meets the QRD.
 Recommended Prep:
