I am a 60-something year old from England. I have a B.Sc. and doctorate in science subjects and still retain a ravenous appetite for scientific knowledge of all kinds.

I took an extended break from Wikipedia for about 10 years, but I am now active again.

My contributions

 * Various contributions to pages about Cornwall.
 * Various pages about astronomy, particularly with regard to calculations of astronomical events and phenomena. The following are a few examples:
 * Solar eclipse
 * Aberration of light
 * Astronomical nutation
 * Stellar parallax
 * I am particularly proud of the following couple of biographies that I have significantly expanded:
 * Ernest William Brown – mathematician and astronomer, and unsung hero of mine
 * John Gilchrist (linguist) – he is an ancestor of mine

To do

 * Finish rewrite of George Linley
 * Write stub for James Burton (clergyman)
 * Tidy up William Balmain

Other pages

 * This is my personal sandbox. It may contain nuggets of new information, but most probably is just a working draft of something.
 * Second sandbox
