6 pm: Opening Reception begins.

7 pm Lecture: Tim Flaherty “Betweeness: the mathematics of being between”
“What does it mean for an object A to be between objects B and C? This introductory talk will review the notion of distance – first in the ordinary sense, measured in familiar terms such as inches or miles. Then distance will be considered in more abstract terms, as considered in many applications in mathematics. Can we define the distance between arbitrary objects? Yes! We’ll consider the idea of betweeness in general; for example, what would it mean to be between an apple and an banana?”

Tim Flaherty has been teaching mathematics for over 25 years. He has published several books in Calculus and Linear Algebra. He is also an ultra-marathon runner, recently completed his first 100 mile race. He lives in Allison Park with his wife Fran and their sons, Liam, Sean, & Lucas.
