Using mathematical methods he helped develop, Alejandro Rodriguez has calculated Casimir forces in these and other complex structures.

Forceful thinking

June 16th, 2010 Updated: November 30th, 2011

A quantum curiosity called the Casimir force gums up micro- and nanomachines. Work at MIT led by a newly minted alumnus of the DOE Computational Science Graduate Fellowship suggests uses for the force – and ways around it.

This shows the Western North American power grid with the analysis results of 200 overlaid possible contingencies. Red areas indicate vulnerable portions of the power grid that network operators must address. Gray areas are causes for concern and green areas are safe. Overlaying the 200 sets of risk-level data allows operators to visualize the collective risk of contingencies on the system.
