In the November 2015 Issue
Arch and Scaffold: How Einstein Found His Field Equations
In his later years, Einstein often claimed that he had obtained the field equations of general relativity by choosing the mathematically most natural candidate. His writings during the period in which he developed general relativity tell a different story. — Michel Janssen and Jürgen Renn
What Every Physicist Should Know About String Theory
Some of nature's rhymes — the appearance of similar structures in different areas of physics — underlie the way that string theory potentially unifies gravity with the other forces of nature and eliminates the ultraviolet divergences that plague quantum gravity. — Edward Witten
Granular Crystals: Nonlinear Dynamics Meets Materials Engineering
The freedom to choose the size, stiffness, and spatial distribution of macroscopic particles in a lattice makes granular crystals easily tailored building blocks for shock-absorbing materials, sound-focusing devices, acoustic switches, and other exotica. — Mason A. Porter, Panayotis G. Kevrekidis, and Chiara Daraio
