Physical Form

In the ancient past there were varying levels of belief in a flat Earth, with the Mesopotamian culture portraying the world as a flat disk afloat in an ocean. The spherical form of the Earth was suggested by early Greek philosophers; a belief espoused by Pythagoras. By the Middle Ages—as evidenced by thinkers such as Thomas Aquinas—European belief in a spherical Earth was widespread. Prior to circumnavigation of the planet and the introduction of space flight, belief in a spherical Earth was based on observations of the secondary effects of the Earth's shape and parallels drawn with the shape of other planets.

Famous quotes containing the words physical and/or form:

    My vocabulary dwells deep in my mind and needs paper to wriggle out into the physical zone. Spontaneous eloquence seems to me a miracle. I have rewritten—often several times—every word I have ever published. My pencils outlast their erasers.
    Vladimir Nabokov (1899–1977)

    The Republicans hardly need a party and the cumbersome cadre of low-level officials that form one; they have a bankroll as large as the Pentagon’s budget, dozens of fatted PACs, and the well-advertised support of the Christian deity.
    Barbara Ehrenreich (b. 1941)
