Instead of replying directly to each point you said I refer to the project page WikipediaWikiProject MagicMagic Methods and Exposure where this issue is being treated Although this section has its focus on the legal aspects I agree with the basic idea that the exposure of magical tricks is in agreement with Wikipedias policy provided that the guidelines of proper attribution and so one are followed especially avoid original research unless this research is limited to trivial conclusions or eg elementary mathmaticalgeometricphysical relations  Some words about suggested methods in WP Even if someone finds out all modern tricks it would not be possible to describe them here because it would be far beyond the scope if an encyclopedia Therefore the damage to the magical community would be fairly small But the description of one important trick even if there are others that work completely different would give the reader an impression about the arts behind the arts Again an analogon To watch a space shuttle launch is really impressive unfortunately I never had an opportunity to watch one But to watch it and to understand how it works is even more impressive And yet another point The description of selected good trick methods would give the reader an impression how far an illusion can be from reality and how much of our awareness of our surroundings is based on interpretations and interextrapolations of or brain rather than on facts Thus to learn about selected magical tricks means learn much about oneself
