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! Could science fiction uncover the true nature of physics? In a nutshell is science fiction? In fact, as a product of our human minds physics could very well be fiction. And the following shows how "the mathematics of physics" are as appealing as "fiction". 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 multiplied by constant acceleration a). Galileo is showing experimentally or empirically describing that no matter their weight all objects in a given place fall at the same rate "a". Galileo unambiguously contradicted Aristotle's 2000 years old doctrine. 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. 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 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 on earth the force of gravity "F" that acts on any mass "m". This equation appears to be truly scientific, because it doesn't appear to be derived from experimentation; it is instead the synthesis of two abstract entities that are the mathematical works of Galileo and Kepler. The beauty of this "scientific law" (all mathematical) is that when combined with Galileo expression above, it now proves scientifically that no matter their mass and shape all objects fall at the same rate. The combination of the two (F=m.a=Gm.mearth/d2) reduces to a constant (a=G.mearth/d2), showing scientifically (that is with mathematics) the accelerated motion of any falling object is independent of the object mass. Now one is led to think that Newton provides a scientific demonstration of the real phenomenon that is accelerated motion under the force of gravity! As if the human mind on par with Whoever invented Nature, did not need Nature, but only mathematics, to bring into the open the gears behind Nature's laws! Simply speaking it implicates that our human minds could as well have invented that Natural law. For the layperson who is this writer, and who does not understand the complex mathematics of modern physics, this 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, Newton mathematically integrated Galileo's work describing the phenomenon at our human scale, with Kepler's work describing it at the solar system scale. Rather than a scientific proof Newton's equation reflects the fact that Nature is consistent with itself, at all scales. And that does not in any manner diminish Newton's accomplishment. Only a genius could come up with such a simplification about the understanding of Nature that we human had at the time. The point is that no matter how intellectually appealing the mathematics, no matter how accurate the predictions, physics mathematics nevertheless do not provide a clue on what is gravity. Even though physics mathematics provides results of exquisite accuracy, which can be used in applied physics, physics' mathematics describe and do not explain. Physicists agree on that point, they claim that Newton's equations are just that, mathematics. Now physicists claim that Einstein's space-time deals with reality, yet let's face it Einstein's space-time looks as fictitious, if not more, as the force of Newton! By contrast gravimotion while non-mathematical is a pragmatic description of the reality of gravitation. That description is based on the real phenomenon of motion, and not on force not on space and not on time. Most importantly though, gravimotion, while pragmatic provides a logical (and not philosophical) interpretation of Nature. Strangely enough, motion is not considered to be a physical phenomenon in physics. Time, space, force and inert mass are the fundamental tenets of physics, while motion (speed) is relative that is elusive or fictitious! In gravimotion, motion is a real entity; time, space, speed and acceleration (both fashioned out of time and space) are all fictitious!
