Crumpling, buckling, and cracking: Elasticity of thin sheets
Deforming thin surfaces creates a rich set of structural and dynamical problems combining physics and geometry.
Casimir forces: Still surprising after 60 years
The once startling idea of a connection between quantum fluctuations and forces has by now been applied throughout physics. Nonetheless, experimentalists and theorists alike still find challenges in the Casimir force.
Memories of Feynman
In this memoir, written in 1983, a contemporary and close friend of Richard Feynman’s recalls the blossoming of Feynman’s genius with vignettes from college, Los Alamos, and afterward.
