Hi All, I am not a physicist, so my question/comment may be stupid, but if I dont ask I will surely stay stupid, so I'll ask. I understand that particles show both particle-like behaviour (when measured or "observed") and wave-like behaviour (when expanding, not observed). My question: does observation or measurement not simply mean "question it with our existing mindset"? To me, it seems obvious that if we question nature with our particle-mindset (or with what do we find out that it is a particle?) it is not surprising that we get a particle back as an answer. In other words, may we have only waves and no wave-particle duality? I've also tried to make this point on my recent blog post, where I question http://www.spreadinghappiness.org/2009/12/no-emptiness-stillness-or-eternity-questioning-physical-concepts-in-light-of-typical-human-thinking-mistakes/" [Broken]. A reply would be very much appreciated!
