Internal stress in a glass material is an important source of strength. Theory and experiments provide a new molecular-scale understanding of the process by which such stress develops.

An equation that describes a wide array of phenomena can be directly tested by watching the equivalent of a drying coffee drip.

A projectile striking granular material generates a series of acoustic pulses that propagate down from the impact site.

Charged beads floating in a plasma spontaneously form a two-dimensional liquid consisting of small, ordered regions that slide past one another and may mimic the motions in real liquids.

Two-dimensional simulations provide the first element-by-element accounting of the fluid and grain flow in an underwater avalanche.

The atomic force microscope, introduced in 1986, provided atomic-scale pictures of surfaces, with few limitations on the type of sample.
