Students began this morning working on their projects.

After lunch Matt Leonard gave a riveting talk about knot theory! Students learned about the general properties of knots as well as some of the invariants that are known for knots. Some of the highlights were proof by roller coaster, tricoloring using the paint bucket, performing Reidemeister moves, and unknotting algebraic knots.

The students will be giving updates at 4:00 and we are looking forward to seeing their progress.
