Re: seminar
I have not done this, but a few thoughts: I would start by talking (preferably outdoors) about the sun and where it casts a shadow over the course of a day and a year. This is where it is important for the students to develop some understanding. Nothing is gained if at the end the whole thing seems just like 'magic'. I would not emphasize the layout of dials (advanced topic) but only the fact that a horizontal dial (plate and gnomon) must be designed for the specific latitude. (Anno's book of sundials is wonderful for its pop-ups of horizontal sundials at different latitudes.) And I'd talk about kinds of time (following Waugh) -- just sufficient to explain the need for corrections for equation of time, longitude, and daylight savings time. (My own approach is not explain how the sundial has to be "corrected" to get "watch time" but rather how our "watch time" has to be corrected to get correct local solar time.) Then a bit of a discussion about how to tell a decent dial from a "garden shop" decorative item, and how to install it. And I'd try to have a bunch of good illustrations (and examples) of horizontal dials, to emphasize what elements are necessary to accurate functioning, and what is the scope for artistic creativity. [My own thinking about teaching about dials -- for understanding -- would start with the earth as a sundial, then move to a small globe as a model. Then I would progress to an equatorial dial (as an abstraction of the globe's equatorial plane and the polar axis). All with lots of hands-on models. In a brief lesson I would probably not even get to horizontal dials. If I did talk about a horizontal dial, I would try to demonstrate it as a slice through a cylinder with 15 deg sectors (or equivalently, as a projection on a plane not parallel to the equator).] Good luck! and I look forward to other folks' ideas!

Thanks for the offer. Please forward a copy.
I'll let everyone know how my talk turns out..this will be the first one
I've given.

Re: seminar

The 3D model sounds like something I've been mulling over for years. Please
send me a copy too.

RE: seminar
Tony
Yes please for some pdfs when you are sending them out (I didn't seem to get
your offer of some weeks ago?) - I am down to give a member's short talk to
the Southern Section of Antiquarian Horological Soc in September and might
find some of your images useful there, especially of the multiple dial
model. I've used the cardboard ones from the Magdalen and Bear book quite
successfully in the past. It has to be a short talk - one of three after
the AGM - which I find more difficult than a long one, which I've done
several times! I must think of a theme (preferably one on which I have some
slides). Sundials in Sussex, perhaps - or in Jaipur!
Regards
Andrew

I recently gave a similar talk to a client Rotary Club ("All about
Sundials in 15 minutes") and prepared an OHP transparency which shows the
essential relationship between an Equatorial Dial and a Horizontal Dial
but also goes on to show vertical and Polar surfaces arranged around a
common polestyle. It also includes a north-facing Vertical surface. The

I have to conduct a 15-30 minute workshop on horizontal sundials. Real basic stuff, how to use the sun to tell time, how to make and position a simple horizontal dial, etc.. Has anyone ever had to give such a talk and if so what type of preparation, materials, handouts, slides, etc... worked best. Thanks. Greg -
