I am wondering about QM observation in terms of , in Penrose way I call, the unitary process (U) and the reduction (R) of states. R occurs for any intended physical observation. Does R occur also in unintended situation? For examples(adsbygoogle = window.adsbygoogle || []).push({});

- We make a fog chamber and observe the white streak lines that show positions of charged particles. R occurs there. In natural fog in mountains area, do white streak line appear?

- We can calculate probability of transisition of the states in time interval: R(0) →U→ R(t).

Do we have to worry about unintented R during the process : R(0) →U→R→U→ R(t), R(0) →U→R→U→R→ R(t) or so take place and disturb our calculation?
