The late 19th and 20th centuries have seen advances in technology and scientific understanding the likes of which have not been seen before in such a short amount of time in known Human history. In the last hundred and fifty years science has advanced so much that one would barely recognize the lifestyle of Humans before all these technological wonders. In fact, if the scientists and thinkers of pre-industrial society had had a glimpse of the technology available to the average early 21st century man they would probably surely think some sort of sorcery was involved and would not believe for one moment that all these technological innovations were based on concepts of the governing laws of the universe that have applied all through mankind's history. In fact, modern science looks pretty solid when one examines all of its wondrous creations and the fact that new ones keep coming out daily. For instance, it would appear that modern science has correctly solved the understanding of concepts and principles which govern how electricity flows in a circuit. After all, computers, hair dryers, TV's and other such electronic devices use this scientific understanding to function properly and in turn most people use such devices every day, thus is this science proven every time such a device is used successfully? It is easy to classify such scientific understanding as fact when devices built upon the science work and work very dependably at that. However is this science fact as would appear, or is merely conjecture based upon an observable phenomenon? Perhaps something entirely different happens when we throw the switch on a light bulb and it illuminates than what science says happens. Even though the light bulb lights up every time, that does not necessarily mean that the scientific understanding of how the light bulb works is true.
             Take for instance the scientific principles of projectile motion. In a simplified form, current physics explains...
