The physics behind four amazing Demonstrations David G. Wiley wrote a paper called “the Physics Behind Four Amazing Demonstrations. In this paper he starts out by telling about his experience in a physics class that bored him. He later discusses a move that changed his physics experience thanks to a new instructor. This instructor demonstrated physics rather then just speaking about it. Today David Wiley does the same thing in his classes. He uses some demonstrations that are both new and familiar. David show how these demonstrations can fool a person into believing that they are witnessing magic but it is only an illusion. What I got from this article is that some things though they seem real simple they are actually pretty complex. Some magic tricks that are sometimes seen on TV actually take time and thought to prepare and demonstrate. David Wiley opened my eyes to realize that there are a lot more things that can be and are scientific. The Magic tricks that I am often fascinated with are really a scientific procedure that takes time and knowledge. I wonder if walking on glass and lying on a bed of nails was discovered by a magician or a scientist? I also wonder who was the more daring of the two to actually go through trail and error for these mind boggling demonstrations? I used to wonder about these types of things before. I would think how they are done, what do they do. Know I can look further into it knowing that it has some type of scientific background.
