    Re: Stereographic Projection of the Ecliptic

    Newyddion da!  It’s St David’s Day.  The daffodils are starting to bloom, and my second-hand copy of Schroeder’s Practical Astronomy (Seryddiaeth Ymarferol), as recommended by Geoffrey Kolbe, has arrived from Anybook Ltd.  Why the Welsh theme?  Well, it’s ex-libris from the University College of North Wales, Bangor, and it’s only seventh-hand.  Between being bought in November 1957 for 25 UK shillings (25/-) and today, it’s been borrowed six times; the last time being 21 years ago in February 2000.  That averages approximately once per ten years.    It’s good to know interest in practical astronomy is booming in North Wales.   I was relieved to find the text is in English not Welsh.  It looks pretty good.  I suspect it’ll jump to the front of my reading on the exercise bike queue before ‘The Light Ages’ and ‘Heavenly Mathematics’ are completely finished.  I’m getting a bit bored with the Merry Monks of St Albin’s & Tynemouth.  DaveP
