If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

This is an interesting treatment of superposition incorporating a function of time reversal, assuming time is in fact one dimensional. It is we whom choose what a dimension is, of course, and that is simply that by which we make some measure. So what would be time reversal here may be an intersection in multi-dimensional time, and that multi-dimensionality being inherent in each decohered particulate fluctuation. The superpositional state in the micro-realm may be *an-entropic*, there being not cost of energy in the change of state, simply the same quantity of energy being either volumetrically localized or discrete (oops, diffuse), Just too many events too quick to individually observe. Nice civil discussion by participants also, inquisitive.

Bear with me, what's not quantum mechanical about this?

There is a syndrome in clinical psychology that is one of the earliest identified and most intensely studied in the history of psychology, and which is known to afflict a small but significant percentage of population globally in such a consistent yet apparently random manner that you would have to be a monk not to have encountered it....
