Fiction to physics relationshipThe best science fiction novels and movies rely on the weird aspects of physics.The closer to physics' theories the better the science fiction! Conversely, would science fiction uncover the true nature of physics? In a nutshell is physics science-fiction? Should physics be fiction it could only be so in its quality of being a product of our minds. And the following shows how appealing "the mathematics of physics" can be. Physics in its infancyAristotle (384-322 B.C.) thought that a heavier object falls faster than a lighter one. And that has been the doctrine for close to 2000 years until Galileo (1564-1642) decided to "make" the experiment and verify physically the doctrine. Galileo was the first to experiment and relate mathematically the motion due to gravity to the then emerging concepts of time and distance. Essentially he established this law: any mass "m", under the force of gravity "F" is submitted to an acceleration "a", "F=m.a" (m multipled by a constant acceleration a). Showing experimentally or empirically describing that no matter their weight all objects fall at the same rate. Galileo unambiguously contradicted Aristotle's 2000 years old doctrine.During that time Kepler, who was Galileo's contemporary, established the empirical laws governing the motion of the planets. Physics to mathematics relationshipNewton was born on the year Galileo died. Newton's genius was to make a synthesis of both Galileo's and Kepler's works, he came up with the Universal gravitation law also called the inverse squared law:F=G.m.mearth/d2, which provides the force of gravity "F" on any mass "m". The beauty of this "mathematical law" is that when combined with Galileo expression above, it proves scientifically that no matter their mass and shape all objects fall at the same rate. The combination: F=m.a=Gm.mearth/d2 reduces to: a=G.mearth/d2. Showing the acceleration "a" is independent of the falling object mass "m". Evidently the effect of the air is disregarded. If one makes the experiment with a feather one has to do it in a vacuum chamber. Whereas Galileo made an empirical discovery Newton provided a mathematical, so called scientific proof of it! For the layperson who is this writer, and who does not understand the complex mathematics of modern physics, the above example first uncovers then explains the "love" physicists have for the "beauty" of mathematics. The truth (that is the reality) behind physics' mathematicsThe point of this page though, is to also mention that the above example is actually exclusively based on empirical measures. Kepler's laws were based on Tycho Brahe's astronomical data that the later spent a lifetime to compile.Essentially rather than proving scientifically that all bodies no matter their weight fall at same speed, the above shows that nature is consistent with itself. As a matter of fact Galileo proved before Newton that all objects, no matter their weight or density, fall at the same rate! Newton made the law more accurate, involving the earth's matter and the factor G. Do not get me wrong that is a great achievment. Yet no matter its intellectual appeal, the above doesn't in any way "explain" how gravity works. The above shows how physics' mathematics remain within a fictitious world. By contrast the theory of gravimotion provides a non mathematical explanation of the reality of gravitation, which is beautiful in its simplicity. Read more about Gravimotion. |
