A new course, MATH 033 - Mathematics for Sustainability, will be introduced at University Park this spring. This course meets GQ requirements and is designed primarily for students not in scientific and technical majors (which is also the case with MATH 034, MATH 035, and MATH 036). Its key mathematical ideas of measurement, change, risk and connectivity are integrated around the central theme of environmental sustainability. Students completing the course will gain the quantitative skills needed for informed participation in discussion of sustainability at the local, national and global levels.
