Woden Kusner, University of Georgia, Measuring chirality with the wind
- This event has passed.
“Are your shoes more left-or-right handed than a potato?”
We can begin with the hydrodynamic principle that chiral objects rotate when placed in a collimated flow (or wind). This intuition naturally leads to a trace-free tensorial chirality measure for space curves and surfaces, with a clear physical interpretation measuring twist. As a consequence, the “average handedness” of an object with respect to this measure will always be 0. This also strongly suggests that a posited construction of Lord Kelvin–the isotropic helicoid–does not exist. This is joint with Giovanni Dietler, Rob Kusner, Eric Rawdon and Piotr Szymczak
