If you are not prepared to resign or be fired for what you believe in, then you are not a worker, let alone a professional. You are a slave. - Howard Gardner

"Embracing a different vocabulary, Mihaly Csikszentmihalyi has described a highly sought-after affective state called the flow state or flow experience. In such intrinsically motivating experiences, which can occur in any domain of activity, people report themselves as fully engaged with and absorbed by the object of their attention. In one sense, those "in flow" are not conscious of the experience at the moment; on reflection, however, such people feel that they have been fully alive, totally realized, and involved in a "peak experience." Individuals who regularly engage in creative activities often report that they seek such states; the prospect of such "periods of flow" can be so intense that individuals will exert considerable practice and effort, and even tolerate physical or psychological pain, in pursuit thereof. Committed writers may claim that they hate the time spent chained to their desks, but the thought that they would not have the opportunity to attain occasional periods of flow while writing proves devastating."

For instance, there is a significant population that lacks facility with formal examinations but can display relevant understanding when problems arise in natural contexts.

Both science and history are moving targets. Scholars in the twenty-first century are much more aware than those of earlier generations that scientists operate under the influence of powerful metaphors (science as exploration, discovery, documentation, thrust and counterthrust), and that both the scope and the tools of history undergo continual changes. Still, most scientists and most historians would concur that the broad strokes I've sketched, when viewed from sufficient distance, are accurately rendered—that is, that science and history are each in pursuit of statements that represent the truths ascertained by their respective disciplines
