Delta Wave Activity

Famous quotes containing the words wave and/or activity:

    “Now I stand as one upon a rock,
    Environed with a wilderness of sea,
    Who marks the waxing tide grow wave by wave,
    Expecting ever when some envious surge
    Will in his brinish bowels swallow him.”
    —William Shakespeare (1564–1616)

    “Play for young children is not recreation activity,... It is not leisure-time activity nor escape activity.... Play is thinking time for young children. It is language time. Problem-solving time. It is memory time, planning time, investigating time. It is organization-of-ideas time, when the young child uses his mind and body and his social skills and all his powers in response to the stimuli he has met.”
    —James L. Hymes, Jr. (20th century)
