Another source of error apart from those mentioned in the original post is
how accurate can a wall's declination be measured, say to half a degree.
And what error would half a degree make depends on the size of your
sundial. We are also assuming the wall is planar and built perfectly plumb!

Very nice images, thanks!

I agree that showing local time on a sundial is something to be encouraged.
The drawback is that it has to be explained every time to everyone -
otherwise the impression being given is that "it does not work" !

I join in all these eulogies, there is definitely the same common sentiment.
I think it would be very fitting if an existing large Dutch public sundial,
or a new one, be named after him.

Hello Jim,
Thank you for your email,
It was great working on this project (I made the calculations and concept
design), which will hopefully help many students appreciate the beauty of
science and art.
Best regards,

The Konigsberg bridges dilemma is particularly intriguing when explained to
the "non-mathematicians", I suggest you have a look at this for a thorough
explanation

Dear all,
An analemmatic sundial (humbly designed by the undersigned) has now been
completed in the village of l-Għarb in Gozo (Malta). We just need to
indicate the monthly durations of June and December.

Good morning,
I have designed an analemmatic sundial and would like someone to 'peer
review' it and re-calculate my design.
Is anyone willing to do this please? I can supply the file in DWG or DXF
formats.
Best regards,
Alex

Hello all,
Have a look at this interactive website
http://www.sunmoonscope.com/
Quite a useful teaching tool.
There are other 'scopes' as well (solar system, astrology), at the top
right hand corner of the screen.
best regards,
Alex
