Hypnotists in Einstein criminal cult know how to trap forever a long train inside a short tunnel http://www.youtube.com/watch?v=VSRIyDfo_mY&mode=related&search= but when they trap a 80m long pole inside a 40m long barn, trapping is not forever but only for a very short time: http://www.math.ucr.edu/home/baez/physics/Relativity/SR/barn_pole.html "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn....So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn." In order to solve the problem, philosophers in Einstein criminal cult have organized a symposium: http://www.ias.umn.edu/timeandrelativity.php "This three day symposium, organized by Professor Michel Janssen (History of Science, Technology and Medicine) and Professor Antigone Nounou (Philosophy), will address issues raised by Harvey R Brown's Physical Relativity. Space-Time Structure from a Dynamical Perspective (Oxford: Oxford University Press, 2005), co-winner of the 2006 Lakatos Award, awarded annually by the London School of Economics and Political Science for outstanding contributions to the philosophy of science. " Harvey Brown's most important discovery is described by Bradford Skow, University of Massachusetts: http://ndpr.nd.edu/review.cfm?id=6603 "There are many things I might be asking when I ask someone to explain length contraction. I might be asking, "Why do different inertial observers (who are not at relative rest) disagree about the length of a given (inertially moving) rod?" Or I might be asking, "Why is a moving rod shorter than its stationary counterpart (of the same proper length)?" Or I might be asking, "If you take a rod that is initially at rest (in your frame of reference), and accelerate it, why is it shorter after you accelerate it than it was before you accelerated it?"......I'm not sure what Brown thinks about geometrical answers to the first why-question, but he certainly thinks that geometrical answers to the second two why-questions are bad explanations. He thinks that good answers to these questions say something about the way in which the forces holding the parts of the rod together depend on velocity of the rod. Only that is a story of what causes the particles to get closer together, and so what causes the rod to shrink." So at the symposium Einstein philosophers will try to understand what happens to the forces holding the parts of the 80m long pole together so that the particles of the pole eventually get closer together, the 80m long pole shrinks to a 40m long pole and so gets trapped inside the 40m long barn. If Einstein philosophers can understand and then explain this to brothers physicists, brothers physicists will stop reopening the doors of the barn "pretty quickly" and the 80m long pole will remain trapped inside the 40m long barn forever. http://www.bnl.gov/community/Tours/EinsteinPics/Einsteine.jpg Pentcho Valev
