WHY Earth's not apt to move, but slow and dull, <br />Is, Atomes flat no Vacuum hath but full. <br />That Forme admits no empty place to bide <br />All parts are fil'd, having no hollow side. <br />And where no Vacuum is, Motion is slow, <br />Having no empty places for to go. <br />Though Atomes all are small, as small may bee, <br />Yet by their Formes, Motion doth disagree. <br />For Atomes sharp do make themselves a Way , <br />Cutting through other Atomes as they stray. <br />But Atomes flat will dull, and lazy lay, <br />Having no Edge, or point to make a Way.<br /><br />Margaret Cavendish<br /><br />http://www.poemhunter.com/poem/of-earth/
