The future would be a race between education and catastrophe.

The sad fact of today’s life is that science gathers knowledge faster than humans gather wisdom.

Solemn Declaration: 1) We will send articles for review/print only if we think our work significantly alters/extends/simplifies current understanding of the Science and 2) We will not claim novelty in our manuscripts using any wilful embellishments of a literary, graphical, or algebraic nature.  We realize that the peer-review system is severely stressed and deformed by its own weight, and that there is a misplaced emphasis on our rudimentary citation system which might be fast losing its correlation to the real impacts of Science. So it is our responsibility to make an effort; see related article by MV.
