Fluid Beauty
Visualizations of a swirling jet, an insect’s wake, agitated sand, and other types of fluid motion can produce stunning images. The American Physical Society’s Division of Fluid Dynamics annually recognizes research efforts that generate images having both scientific merit and aesthetic appeal. Its gallery of fluid motion features a variety of winning photographs (pdf images) […]

Not-So-Neutral Neutron: Clearer view of neutron reveals charged locales
A sharp, new picture of the neutron reveals that rather than being uniformly electrically neutral, the particle contains regions of positive and negative charge.

Signatures of the Invisible
Contemporary artists worked with CERN particle physicists to create pieces of art that respond to (rather than simply illustrate) the preoccupations of modern physics. This quirky Web site, hosted by the London Institute, provides glimpses of the artworks that resulted from this collaboration. Go to: http://www.signatures.linst.ac.uk/
