Old links
These are links that I may look at one day but are not really relevant
to the main page. They mostly date from the early 2000s. Nothing for
you to see here, move
along.
CV
I am not the Hardcastle responsible for Hardcastle's
Galaxy (or Nebula); this was J.A. Hardcastle, 1865-1917 (see his
paper), the 5th director of the Armagh Observatory.
An upper bound on my Erdös number
of the first kind is 4.
