看看物理系的網站怎麼說觀察者效應
他下面說的就是我說的疊加態。 對電子路經跟蹤測量跟蹤也是所謂觀察者效應的一種。我以前在靈機和這裡都說過，如果你一路跟蹤電子，（你當然是用儀器跟蹤）那麼它就不會有衍射，這跟什麼人的意識完全無關。 比如人用槍能殺人，和人的意識能殺人，完全兩回事啊。 我說的靶壁也是一種觀察，在那裡波函數塌縮，是一般內行的說法。 這還不算物理文獻，只是科普的級別, 讓大家比較容易讀懂. 但比一般的網站靠譜, 不要在網上找到一段話就當真理。在任何物理文獻中都不會有人的意識決定實驗結果這樣的說法。 這完全是外行話。至於有的科學家一直想在公共場合扮演上帝，那是另一回事。一些西方科學家試圖用科學證明上帝，是一個老傳統。 物理界早就把宗教和物理分開了。
這個學校就是那北大女孩失蹤的學校，曾長期在工科排前列，不過最近些年有些下降。它的大門大家應該很熟悉吧？在那裡見過？

Q：the theory of observing changing the observed - Anonymous (age 55) seward, mpls A: In quantum mechanics we learn that the behavior of the very smallest objects (like electrons, for example) is very unlike the behavior of everyday things like baseballs. When we throw a baseball at a wall, we can predict where it will be during its flight, where it will hit the wall, how it will bounce, and what it will do afterward. When we fire an electron at a plate with two closely spaced slits in it, and detect the electron on a screen behind these slits, the behavior of the electron is the same as that of a wave in that it can actually go though both holes at once. This may seem odd, but its true. If we repeat this experiment lots of times with lots of electrons, we see that some positions on the screen will have been hit by many electrons and some will have been hit by none. The observed "interference pattern" for these electrons is evidence of their dual wave-particle nature, and is well described by thinking of each electron as a superposition of two "states", one that goes through one slit, one that goes through the other. To add to this already mysterious behavior, this interference will only happen if both possible paths that the electron can take are not distinguishable. In other words, if we could somehow tell which slit the electron went through each time, we would no longer get the interference. The act of making a measurement of the electrons path fundamentally changes the outcome of the experiment.
In physics, the term observer effect refers to changes that the act of observationwill make on a phenomenon being observed. This is often the result of instruments that, by necessity, alter the state of what they measure in some manner.
