While reading newly released testimony about the
Theranos crash (dodgy dot.com punting a dubious
testing machine. Link) I came upon a conundrum.
"Walgreens ..the drugstore giant had more than 8,000
stores and if Theranos could get its technology into
single one, that would
mean being on almost every
corner in the country."
There are about a million streets (Quora estimate) in
the US, but
apparently only 8,000 corners. Obviously some
intersections may be rounded, but otherwise..
Theranos crash back in the day

||Imagine 4 blocks in a square. Put one store on a corner in the centre and you could say "there is a store on the corner of every block" i.e. you only have to walk around the block you are on to reach a store. That's a divide by 16 right there.
||Even if you weaken the criteria, from "every street corner in the country" to "a store on the corner of every block", it's still not looking good. Imagine a city made up of 10 north-south streets and 10
east-west streets and 100 intersections. To fulfil the criteria of "a store on the corner of every block", every group of 4 blocks needs a store, so for your 20 streets, you'll need 25 stores.
||Step one: designate most thoroughfares as "Way", "Road",
"Lane", "Drive", "Avenue" or, in extremis, "Boulevard".
||Step two: recognize a "street corner" only where one "Street"
crosses another "Street", excluding all of the above.
||Or, better, recognize a "street corner" only where one street
changes direction by more than 45°, but retains its name. The
rest are "intersections".
||wonder if there's a waze style map out there with corners
and corner walkers.
||I've been wondering what Walgreens is going to do with all
the extra rooms they built in their stores in anticipation of
hosting Theranos machines.
