COBBS – Non-biting Midge Experiment

Our search for midge swarms has taken us to many of the public parks within Rome including Riserva Naturale Valle dell’Aniene, Villa Paganini, Villa Torlonia, Parco dell’Acquedotto, Villa Ada, Laghetto dell’EUR and Ponte Tazio. Basically any place with an aquatic or semiaquatic habitat (the larval stage requires water for development) is where midges can be found. Our experimental setup is similar to that of the flocking experiment except that our baseline distance shrinks from 25 m down to approximately 5 – 8 m (depending on our distance to the swarm).… Read the rest

The growth of amorphous order in supercooled liquids

Close to the glass transition supercooled liquids display an impressive increase of the relaxation time, without any clear sign of growing thermodynamic order, nor correlation length. This is at variance with physical intuition, which suggests that a large relaxation time is always associated to a large correlation length. Even though dynamical length scales were introduced and measured, nothing similar was thought to be possible for thermodynamic lengths.… Read the rest

Topological vs. Metric distance

Basically all existing models of collective animal behaviour (bird flocks, fish schools, etc) assume that the interaction between different individuals depends on the metric distance, just as in physics. This implies, for example, that two birds 5 meters apart interact more strongly than two birds 10 meters apart.

Models developed by biologists are based on a “behavioural zones” scheme, where each zone is associated to one of the three basic ingredients of all models: short range repulsion, alignment, long range attraction.… Read the rest
