Topological Cluster State

Famous quotes containing the words cluster and/or state:

    the green hells of the sea
    Where fallen skies and evil hues and eyeless creatures be;
    On them the sea-valves cluster and the grey sea-forests curl,
    Splashed with a splended sickness, the sickness of the pearl;
    Gilbert Keith Chesterton (1874–1936)

    The concept of a mental state is primarily the concept of a state of the person apt for bringing about a certain sort of behaviour.
