John Baez - Mathematical Mysteries of the Periodic Table

Why do atoms behave the way they do? Why do electrons form “shells,” as seen in the periodic table? Why does the first shell hold 2 electrons, the second 8, and the third 18: twice the…

Michael Lemonick - How a Failed Astrophysics Major Became a Successful Science Writer

I knew from the time I was a very young child that I wanted to be an astronomer. The dream lasted until I got to college, where I learned to my dismay that I actually had no passion for doing what an…

Local and global avalanches in sheared granular materials - Aghil Abed Zadeh

We perform a stick-slip experiment to characterize avalanches for granular materials. In our experiment, a constant speed stage pulls a slider which rests on a vertical bed of circular photoelastic…

Exploiting disorder - Sid Nagel

We are taught to understand solids by considering ideal crystals. This approach becomes untenable as the amount of disorder increases; for a glass with no well-defined long-range order, a crystal is…
