TOPIC: Build Your Own Four Dimensional Universe in Under a Minute - and a Parallel Universe, Too by Thomas Forrest Caldwell [refresh]
Essay Abstract
If we live in a three dimensional Universe, are we incapable of visualising higher dimensions? Does the ‘origin’ set at zero in Cartesian geometry limit us to thinking in points? By moving the zeros apart can we obtain a fresh insight into geometry? Look at a simple square. It has four straight edges at right angles. We use this to build a model of a four dimensional universe - in under a minute. In three dimensions 'points' cannot be explored but in four the points become surfaces, which can. Further, changing to spherical geometry results in a system that can cope with an infinite number of dimensions and an infinite number of parallel universes. More exciting is that it can be used on any scale from the whole universe, to singularities thought to exist at the centres of black holes, down to the infinitely small quantum level. All without requiring a single new equation.

If you do not understand why your rating dropped down. As I found ratings in the contest are calculated in the next way. Suppose your rating is 
and 
was the quantity of people which gave you ratings. Then you have 
of points. After it anyone give you 
of points so you have 
of points and 
is the common quantity of the people which gave you ratings. At the same time you will have 
of points. From here, if you want to be R2 > R1 there must be: 
or  / (N_1+1) >S_1/ N_1)
or 
In other words if you want to increase rating of anyone you must give him more points then the participant`s rating was at the moment you rated him. From here it is seen that in the contest are special rules for ratings. And from here there are misunderstanding of some participants what is happened with their ratings. Moreover since community ratings are hided some participants do not sure how increase ratings of others and gives them maximum 10 points. But in the case the scale from 1 to 10 of points do not work, and some essays are overestimated and some essays are drop down. In my opinion it is a bad problem with this Contest rating process. I hope the FQXI community will change the rating process.
