How mathematicians use homology to make sense of topology

Robert Ghrist of the School of Arts & Sciences spoke about homology, which uses algebra to identify holes in a particular topological shape. “There’s a real impetus to have methods that are robust and that are pulling out qualitative features,” he said.
