Delta Wave Activity

Famous quotes containing the words wave and/or activity:

    “Speaking of contraries, see how the brook
    In that white wave runs counter to itself.
    It is from that in water we were from
    Long, long before we were from any creature.
    Robert Frost (1874–1963)

    The teacher must derive not only the capacity, but the desire, to observe natural phenomena. In our system, she must become a passive, much more than an active, influence, and her passivity shall be composed of anxious scientific curiosity and of absolute respect for the phenomenon which she wishes to observe. The teacher must understand and feel her position of observer: the activity must lie in the phenomenon.
    Maria Montessori (1870–1952)
