"Shouldn't this be four? ![..."

The amount of diamond is defined as the number of carbon atoms that are covalently bonded, by electrons, to exactly three other carbon atoms\. A carbon atom is any nucleus containing six protons and any number of neutrons, bound by the strong force\. The utility of a universal history is the total amount of Minkowskian interval spent by all carbon atoms being bound to exactly three other carbon atoms\. More precise definitions of 'bound', or the amount of measure in a quantum system that is being bound, are left to the reader \- any crisp definition will do, so long as we are confident that it has no unforeseen maximum at things we don't intuitively see as diamonds\.
