1. The Scientific Method
As a famous scientist once said, "Smart people (like smart lawyers) can come up with very good explanations for mistaken points of view."
In summary, the scientific method attempts to minimize the influence of bias or prejudice in the experimenter when testing an hypothesis or a theory”

4. Scientific Theory
An explanation of the cause or causes of a range of related phenomena.
Scientific theories, unlike common theories, have been rigorously tested but are still open to testing, revision, and tentative acceptance or rejection.

5. From Wikipedia:
In science, a theory is a proposed description, explanation, or model of the manner of interaction of a set of natural phenomena, capable of predicting future occurrences or observations of the same kind, and capable of being tested through experiment or otherwise falsified through empirical observation. It follows from this that for scientists "theory" and "fact" do not necessarily stand in opposition. For example, it is a fact that an apple dropped on earth has been observed to fall towards the center of the planet, and the theory which explains why the apple behaves so is the current theory of gravitation.

6. Materialism
Philosophical Materialism- notion that the universes consists only of matter and energy, and therefore metaphysical entities do not exist.
Science uses methodological materialism – all explanations can only use matter and energy, and not metaphysical entities

7. Once on a hot July day coming back exhausted from the Post Graduate Clinic, I dropped in as I sometimes did at Marsden [Hartley]'s studio on Fifteenth Street for a talk, a little drink maybe and to see what he was doing. As I approached his number I heard a great clatter of bells and the roar of a fire engine passing the end of the street down Ninth Avenue. I turned just in time to see a golden figure 5 on a red background flash by. The impression was so sudden and forceful that I took a piece of paper out of my pocket and wrote a short poem about it.

8. The Great Figure
Among the rain and lights I saw the figure 5 in gold on a red fire truck moving tense unheeded to gong clangs siren howls and wheels rumbling through the dark city
