Title: A Romance of Many (and Fractional) Dimensions

Dimension seems like an intuitive idea. We are all familiar with zero-dimensional points, one-dimensional curves, two-dimensional surfaces, and three-dimensional solids. Yet dimension is a slippery idea that took mathematicians many years to understand. We will use pictures, animations, and analogies to describe our three dimensions and help us visualize a fourth dimension. We will discuss the history of dimension, the public's and artistic community’s infatuation with the fourth dimension, time as an extra dimension, the meaning of non-integer dimensions, and the unexpected properties of high-dimensional spaces.

The Math Department will hold a reception at 3:30 p.m. in King Building Room 203 with refreshments and desserts. Dave will be in attendance to chat and engage in math related activities. This event will not be live-streamed or recorded.
