Similar examples can be found in physics. Prior to the Michelson-Morley Experiment of 1887, which showed the constant speed of light, the experiments of FitzGerald and Lorentz, which explained the constant speed of light as the contraction of bodies and slowing of clocks, and the subsequent conclusion by Einstein that electromagnetic waves do not require a medium, scientists felt that light required a medium, and thus one was invented-ether (Hawking). These experiments demonstrate yet another aspect of a personal point of view in the pursuit of knowledge; the fact that despite the assumptions a personal point of view brings into a study, such as FitzGerald’s and Lorentz’s assumption that ether did, in fact, exist, knowledge can still be gained from such a study. Despite their assumption, they contributed, through their experiments, the knowledge that light does travel at a set speed. Thus, even when associated with false assumptions brought into an experiment, personal points of view are not always negative. …show more content…

Dalton’s atomic theory, which stated “the atoms were tiny, indivisible, indestructible particles” (Bender), differed drastically from that of the Greeks’ in that it “wasn’t just a philosophical statement that there are atoms because there must be atoms” (Bender). Although Aristotle believed that there are four terrestrial elements, earth, water, air, and fire, Democratus believed that “a piece of a substance can be divided into smaller pieces of that substance until we get down to a fundamental level at which you can’t divide the substance up and still have pieces of that substance” (“Atoms”). Aristotle’s theory was popular, but incorrect; Democratus’s was closer to our current theory, yet he remained relatively unpopular and obscure. This demonstrates of the key way in which a personal point of view can, in fact, retard the pursuit of knowledge. The scientist with the better oratory abilities has his theories more widely accepted. Dalton’s own theory, which extrapolated upon four basic
