Ants' movements hide mathematical patterns

qui, jul 02 2015

When ants go exploring in search of food they end up choosing collective routes that fit statistical distributions of probability. This has been demonstrated by a team of mathematicians after analyzing the trails of a species of Argentine ant. Studies like this could be applied to coordinate the movement of micro-robots in cleaning c...

Quantum physics: Hot and cold at the same time

qua, jul 01 2015

Temperature is a statistical concept. Very small systems, consisting of a small number of particles, are not usually described statistically. Scientists have now measured how quantum systems reach a state with well defined statistical properties -- and surprisingly, they found out that quantum systems can have several temperatures at...
