Classical earthquakes are easily located by triangulation. For more obscure seismic events, geophysicists are developing the trick of playing the movie backward.

Thermal conductivity through the 19th century

T. N. Narasimhan
OpenURL
Show Topic
From 1807 to 1811, Joseph Fourier conducted experiments and devised mathematical techniques that together yielded the first estimate of a material's thermal conductivity. His methodology has influenced all subsequent work.

A method that efficiently produces rectangular films of graphene nearly a meter in diameter may chart a course to commercialization.

Testing the doubly magic character of tin‐132

Bertram Schwarzschild
OpenURL
Show Topic
Adding an extra neutron to a nucleus with magic numbers of both neutrons and protons, and watching how it settles in, tests the shell model and can help elucidate the creation of heavy elements in supernovae.
