Why do bees fuss about so much when they fly, instead of forming a tidy flock like birds? Birds flying in a flock keep to a highly ordered pattern, whereas a swarm of bees is a cloud of chaos. This difference has long puzzled scientists, but now a team of Japanese researchers has come up with a simple mathematical model to explain it. [The researchers] began with a simple analogy. Stars in a galaxy move under the influence of each other's gravity in a way that can be described by Newton' s laws. Identify the influences felt by an insect or bird, the researchers reasoned, and its flying patterns should be just as easy to predict.
