Opera d'abbaco del reverendo padre don Smiraldo Borghetti

It is interesting to read that without numbers the world would be without order,  and a horrible chaos.

Strangely the current popular view (which I do not share) is that the world is chaos, even to the extent that the laws of physics are the casual effect of which universe of the multiverse we happen to inhabit.
