Non-ergodic Behavior and Applications
A so-called non-ergodic behavior happens in spin glasses below the freezing temperature, since below that temperature the system cannot escape from the ultradeep minima of the hierarchically-disordered energy landscape. Although the freezing temperature is typically as low as 30 kelvin (−240 degrees Celsius), so that the spin glass magnetism appears to be practically without applications in daily life, there are applications in different contexts, e.g. in the already mentioned theory of neural networks, i.e. in theoretical brain research, and in the mathematical-economical theory of optimization.

Famous quotes containing the word behavior:
“School success is not predicted by a child’s fund of facts or a precocious ability to read as much as by emotional and social measures; being self-assured and interested: knowing what kind of behavior is expected and how to rein in the impulse to misbehave; being able to wait, to follow directions, and to turn to teachers for help; and expressing needs while getting along with other children.”
—Daniel Goleman (20th century)
