## A New Look at an Old Calculus

Calculus has been around for centuries and has a long tradition of applications spanning the modern history of science. However, the current age is characterized by a sweeping array of new potential applications—to machine learning, AI, robotics, neuroscience, genetics, and much more. In addition, both our curricula and our default modes of instruction (chalk, paper, 4-color texts) are not keeping pace with innovation. This talk will be an argument for updating both the content and the mode of visualization of calculus. There will be lots of pictures, new applications, and even a little bit of the mathematics that lies beyond calculus.

### About the Speaker

Robert Ghrist is the Andrea Mitchell Penn University Professor in Mathematics and Electrical/Systems Engineering at the University of Pennsylvania. Professor Ghrist is known for his work on topological methods in applied mathematics, specifically for applying topology to data analysis and to the study of sensor networks. He has authored a number of textbooks for undergraduate students including Calculus Blue, a comic-book style multivariable calculus text.

The Pi Mu Epsilon lecture series is made possible through the support of the UNL Mathematics Department, the Nebraska Alpha Chapter of Pi Mu Epsilon and the National Science Foundation.
