Norbert Wiener firing of anti-aircraft guns caused Wiener to investigate information theory independently of Claude Shannon and to invent the Wiener filter. (To him is due the now standard practice of modeling an information source as a random process—in other words, as a variety of noise.) His anti-aircraft work eventually led him to formulate cybernetics. After the war, his fame helped MIT to recruit a research team in cognitive science, composed of researchers in neuropsychology and the mathematics and biophysics of the nervous system, including Warren Sturgis McCulloch and Walter Pitts. These men later made pioneering contributions to computer science and artificial
Critical understanding context is not meant in a negative sense; rather it outlines a process of thinking. Critical understanding is used to define the process of formulating and understanding a complex problem or difficult set of ideas. In a general sense, it is, ‘a consequence of men’s [sic] beginning to reflect about their own capacity for reflection, about the world, about their position in the world.’ The notion of critical understanding is closely related to the concept of Critical Thinking, described as, ‘reasonable reflective thinking focused on deciding what to believe or do.’ Critical thinking has also been described as, ‘thinking about
