Welcome!
This is really only meant as a collection of links I use frequently,
so there is no need to send me suggestions for missing links (believe it
or not, this happens!). In addition, you may want to browse around the
site if you are after my contact details for
professional purposes or need a copy of one of my articles (my history of
science papers only). Feel free to drop me a line if you have
any queries! Or click here for
my academic skills training and public speaking site.
Please see our group's PhD
positions available page for any opportunities to pursue a
PhD in astrophysics; if you're interested in a PhD in the
history of astronomy, and
specifically the history of maritime navigation and the
"longitude problem", please get in touch as I have a few
projects in mind!
