word cloud #1: human rule, before present

Almost everyday I come across interesting turns of phrase or figures of thought that make me pause and think: "oh, I should jot this down somewhere." So I'm going to start collecting them here. This will also double as a public bookmarking system since, more often than not, I won't actually have had the chance to study the source of the phrase yet.

My first two entries are from the "Ghost Metropolis: Los Angeles since 13,000" mapping project at Hypercities. I don't know enough about either to explain what they are, so I won't fake it. But I do plan to read through the "Ghost Metropolis" materials, a crazy ambitious history of (what we now know as) L.A. In the course of skimming through the first couple screens these phrases wormed their way into my brain:

1. The Origins of Human Rule of Southern California: which, I learned, began "13.1 to 13 thousand calendar years BP" on Santa Rosa, one of the Channel Islands (when you click on the geolocate button  you swoop in from an outerspace view of the planet earth to this reedy blue dot on a desolate virtual landscape. It's not so much breath-taking as heart-breaking). But to the point: what struck me is this phrase "human rule." Not (just) "human presence," but "rule." I'm intrigued with the idea of politicizing early human life through a multispecies frame. More on this another time.

2. BP / Before Present: I noticed that the "13,000" in the project title doesn't have "BCE" or the old-fashioned "BC" attached. In the body of the text I came across this curious (and perhaps unfortunate) abbreviation, BP. Trusty wikipedia tells me this means "before present." But evidently this present, among the scientists who use this time scale notation system, is not the present per se - but 1950, the point at which modern carbon-dating methods became standard.
     There's a certain shabby beauty in the idea that 1950 somehow constitutes an eternal now (though Wikipedia further informs me that "to account for the concern that the year 1950 has by now moved away from the present significantly, the abbreviation BP has also been re-interpreted to mean Before Physics.") But I wish the idea is as relativistic as the term BP implies. That rather than being a series of fixed points, the past is always relative to the present, always on the move.
