(Phys.org) —Metamaterials are defined as artificial materials that have been engineered to have unusual properties that are not found in nature. For instance, ordinary materials (say, a rubber band) that are under tension ...
Though they are discrete particles, water molecules flow collectively as liquids, producing streams, waves, whirlpools, and other classic fluid phenomena.

(PhysOrg.com) -- By analyzing data from experiments performed earlier this decade at the Oak Ridge Electron Linear Accelerator (ORELA), physicists have made observations that seem to conflict with the widely accepted theory ...
Whether it's the acrobatics of a flock of starlings or the synchronized swimming of a school of fish, nature is full of examples of large-scale collective behavior. Humans also exhibit this behavior, most notably in pelotons, ...
