Re: [Phys-L] [SPAM] Re: lunar craters

[Bernard Cleyet <bernardcleyet@redshift.com>]

Reminds me of reports on the distribution of raindrop impacts.  My search quickly reveals a v. technical paper on the correlation of turbulence and the drop distribution.  So a search of lunar crater distribution results in a distribution discussion and roughly why.  (inter alia)

bc thinks Poisson applies over small regions.  [number not size]

p.s. remember:  lotsa craters in craters.

are craters on the moon randomly distributed?

Here's an article in which the Poisson distrib. is used as a test of the lack of latitude variation in the number. [square root of the mean number]

incds. size distrib.  I only skimmed v. rapidly, so ...
