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:
“The real exertion in the case of an opera singer lies not so much in her singing as in her acting of a role, for nearly every modern opera makes great dramatic and physical demands.”
—Maria Jeritza (1887–1982)
“The complaint ... about modern steel furniture, modern glass houses, modern red bars and modern streamlined trains and cars is that all these objets modernes, while adequate and amusing in themselves, tend to make the people who use them look dated. It is an honest criticism. The human race has done nothing much about changing its own appearance to conform to the form and texture of its appurtenances.”
—E.B. (Elwyn Brooks)
