Hi Rodger

There also maybe teachers in this group who also find it hard to follow. They
might want to use this method in their classroom.
Thank,

Hi Roger and Mitchael,
I'm sure others have thought of and have used these concepts before us.
Sundials have been around for a long time.
What these concepts achieves are:
That all clocks have a energy source to make them work. For sundials it is the
rotation of Earth. And that planet Earth

Alright, acknowledged. But, even so, why not instead have a class design
and build a dial whose construction-derivation would be of interest to
them. ...or even build, or have it built, for them.

An analemmatic dial is more considered more interesting than other kinds
because it is somewhat interactive, but I agree that it is a little
harder to understand. To me though, installing a sundial at a school
isn't just about, or even primarily about, the teaching of the mechanics
of how it

As Hunt pointed out, there might be many locations where an Anelematic is
the only dial that won't be stolen or vandalized. And I like it. But I'd
consider it a last-resort, to be used only when a previous dial has been
stolen or vandalized. That's because I prefer sundials whose
