I am critical about this as it could give the impression of touching esoterism. But having in mind the statical properties of neuronal processing and network properties, quantum processes might be involved at critical bifurcation points .hidalgohttps://www.blogger.com/profile/01104313187133140241noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-49777677163509360112010-03-16T21:25:44.965-04:002010-03-16T21:25:44.965-04:00Hi Steven,

If you know where to go one can simply view them from the land in many places throughout the province.

As I wrote in the post, it's a not-quite central collision, meaning the trajectories of the ions' centers-of-mass are slightly offset to each other.

As Stefan said above, the one-million dollar question is of course how well is that a description of reality. The only thing you can do is compare the results of the simulation with the actual data.
