Welcome to Wikipedia! Your contribution ‎If the probability density at certain points for a particle is zero, does this imply that the particle cannot move across such points was deleted because there was no sign it was intended as an appropriate Wikipedia article. Did you mean to ask that as a question? If so, you can post your question at Reference_desk/Science. Hope that helps. Pan Dan 16:39, 12 March 2007 (UTC)
