Einstein Vs. Newton on Space and Time
Albert Einstein's theories shook the very foundation of reality, challenging the Newtonian view that space and time are absolute. Science historian David Kaiser and physicist Fay Dowker set the stage for this evolution of understanding about time in this clip from the 2009 World Science Fe

Emilie Purvine (3/3/23): Applied Topology for Discrete Structures
Discrete structures have a long history of use in applied mathematics. Graphs and hypergraphs provide models of social networks, biological systems, academic collaborations, and much more. Network science, and more recently hypernetwork science, have been used to great effect in analyzing

Chad Giusti (4/13/22): An approach to assigning semantics to persistent homology classes
Abstract: One of the most difficult questions to field when talking to scientists and engineers about persistent homology is, to paraphrase, "What does seeing this 'hole' mean in terms of my application?" In this talk, I will discuss some of the complexities inherent in addressing that que

Emilie Purvine (5/2/21): Homology of Graphs and Hypergraphs
Graphs and hypergraphs are typically studied from a combinatorial perspective. A graph being a collection of vertices and pairwise relationships (edges) among the vertices, and a hypergraph capturing multi-way or groupwise relationships (hyperedges) among the vertices. But both of these ob
