Observers, consciousness and existence.

by alexeyburov

Here we are keeping all ideas, questions and materials related to the particle-wave dualism problem in QM.

Sharan Kalwani pointed our attention to John Wheeler participatory universe idea suggesting to have a look here.

Mike Albrow sent his unpublished paper, “Cats are either Dead or Alive: Microscopic Entropy and Wavefunction Collapse 

Some recent papers and hopefully useful ideas could be found at wiki page, “Wheeler’s delayed choice experiment“.

In particular, see

Vincent Jacques et al., Experimental Realization of Wheeler’s Delayed-Choice Gedanken Experiment, Science Vol. 315. no. 5814, pp. 966 – 968 (2007). Preprint available at

Dear colleagues, please put your comments below as a material for the future talk!
