RE: Equatorial Ceilng Dial

[Ian Maddocks]

Hi John,

-Original Message-
Let's say you have a spherical room, built like a planetarium, where the
walls curve up into the ceiling and you locate your mirror in the
center.
(Actually, the room would be a quarter sphere, like an orange segment,
with
one flat side being the floor, and the other flat side the southern wall
with the window with mirror).
Would the sunspot be perfectly round all the time?  Also, what would the
hour and declination lines look like? (Like the lines on a
hemispherium?)
Would this be called an Equatorial Ceiling Sundial?

I believe what you're describing is rather like the Helios XXII
sculpture by Barry Mason, except he uses a pond rather than a mirror to
much more dramatic effect.
See  http://www.rbs.org.uk/cgi-bin/getMember.cgi?member=083
Barry gave a talk on his sun sculptures at the 2000 BSS annual meeting
2000.

Re: OS Map refs.

[Ian Maddocks]

Am I correct in thinking that:
OSX the 'Grid East Value' and
OSY the 'Grid North Value?   in this context?  O-)


Yes - if you look on the OSGB map included in the BSS glassary
http://www.sundialsoc.org.uk/glossary/ap11/ap11.htm
the 0-700km eastings and 0-1300km northings are noted up the sides.

I first found this form of grid reference used last year - at the end of the 
Foot  Mouth crisis i downloaded a table of footpaths in the lake district 
that were open , given as 12 figure references!
for example those in NX grid square were 3EEEee5NNNnn.  ie what would 
normally be NX EEENNN.   Yes with enough digits they were quoted to the 
nearest meter!

Re: A sundial at the rebuilt World Trade Center?

[Ian Maddocks]

I wonder if anyone else noticed this, or if anyone knows any more about
a sundial of any nature being included in plans for the rebuilding of
the World Trade Center.


From the descriptions in the UK papers of the 2nd batch of entries, i 
remember that one included a private space for relatives that would be in 
shadow from the time of the first impact to the time of the 2nd collapse, 
calculated for 9/11.I don't beleive that this was the design chosen 
however.

In the Bond film GoldenEye (at 23 minutes) there is a Pilkington  Gibbs

the set dressing people had just been told to find something scientific
and brassy to put there.   For a couple of frames it fills the screen,
so much so you can even make out the little holes in the bases of the
uprights!

There's also the sundial that Mr Burns collapses over after getting shot

Re: AW: Clever stuff!

[Ian Maddocks]

Tony

Indeed these things have been around for a good few years!

I have still an article in a lasers/optics trade magazine from December 1997 
when the technique was first announced by the Fraunhofer Institute in 
Dresden.Only one laser is involved, a short pulse Nd:YLF Neodinium : 
Yttrium something Fluoride. The focal spot is so small that the damage 
spot is made ony where you want it.


Several years ago laser oranments started appearing in shops and in Chester 
too there's a shop doing an almost while you wait service zapping the block 
in a little cubicle within the shop.   I;ve never been in to ask if they;ll 
take a TurboCAD dxf instead of scanning you head!


For making Spectra like sundials these would be so-so, so long as you've 
calculated out the refraction to the depth of construction,  ie the zapped 
glass is the receiving surface, not as good as sandblasting though.  And 
(after 2 minutes experimentation with the ornament off my windowsill) i 
don't think that enough glass would ever be destroyed to make a dense/opaque 
enough gnomon also in the glass.

I too have seen this technique used over the past four or five years.  The

of a friend was busy developing the technique with his company then.  Such
pieces have been commonly sold as paperweights and ornamental pieces for 
quite a

while.

In fact last year there was a company in a local shopping Mall (Milton 
Keynes in
the UK) who were producing 3d portraits while you waited.  They took a 
couple of
photographs which were scanned and then about 15 minutes later, hey presto

3d portrait inside a glass paperweight.  They were doing great business. 
But as

for a sundial, I don't think so, call me a sceptic.

Quoting Hannes Kühtreiber [EMAIL PROTECTED]:


this laser engraving technique is not new at all, I remember seeing
some pieces more then five years ago, and they were nothing new then.
however, due to legal disputes about the patent the method is not -or
has not been- widely used.

I am not sure it would be very useful for sundials. You'd have to
produce a very tight layer of dots to show the shadow well. While the
newer machines can produce much finer dots (I think the piece in your
picture was made by an older model), they are still far from it.

why not sandblast the backside of a plate of glass?

  Subject: Numb3rs
  
  List members who can view U.S. television may want to watch the CBS show 
  Numb3rs on Friday night, October 14 (10pm Eastern) for a sundial/shadows 
  tie-in. The title of the episode is "Obsession".
  
  As you may know, the Numb3rs series deals with a mathematics professor 
  who helps his FBI agent brother solve crimes through the miracles of 
  mathematics. The producers make a real effort to stick to reality and 
  the solutions they present are intended to be possible in the real world (or 
  at least what Hollywood views as the real world!)
  
  A few months ago, while planning was underway for the Oct. 14 episode, I 
  was contacted by one of the show's researchers. He wanted to know if it 
  were possible to use the shadow of a building in a date/time stamped photo as 
  a poor man's GPS system - using mathematics to locate the building 
  itself.
  
  We had the requisite discussions about the fact that the shadow of a 
  building might be rather diffuse near its end point, that the slope of the 
  ground on which the shadow is cast could be a problem, that the time stamp 
  placed on a photo by a camera might be significantly different from the real 
  time, that the level of precision needed for their plot just might not be 
  realistic, etc., etc. All of that came under the rubric of 
  suspension of disbelief - and we then had to address the basic theoretical 
  question.
  
  I told him I didn't see how it could work with a single photo but that if 
  the script could be arranged to involve 2 photos taken at different times - 
  then we could do something. So we began working things out.
  
  I suggested that they use a shadowcasting object shorter than a building 
  - initially they mentioned a skyscraper but I noted that it would be hard to 
  get the skyscraper and its shadow in one photo - and that the FBI would 
  probably be able to identify any such building in the Los Angeles area without 
  resorting to these measures. They would need something of known height 
  and they would need some way in the photo to measure the length of the 
  shadow. For the latter problem, I suggested that they include some 
  brickwork on the ground - knowing the standard size of the bricks, they should 
  be able to determine the length of the shadow falling across the bricks by 
  using the simple Pythagorean theorem. To cast the shadow, they 
  settled on a basketball hoop - assuming that it was set at the regulation 10 
  foot height, that the brick patio was level, that they could determine what 
  point on the hoop cast what point on the shadow, and how far that point was 
  from the pole supporting the hoop etc. etc.
  
  With this done, Charlie (the math prof.) can calculate the sun's altitude 
  at the date and time of the photo(s); it's simply the arctangent of the 
  (height divided by the shadow length).
  
  Since Charlie occasionally scribbles his equations on a blackboard as he 
  explains the math behind his solution, I provided the following:
  
  sin(alt)=sin(lat)*sin(dec)+cos(lat)*cos(dec)*cos(tau-eot-long+merid) 
  (longitude increasing to the west)
  
  Charlie calculates the solar altitude (alt) from the shadow and known 
  height of the hoop in the photo. The photo gives the standard time (tau) 
  and the date, which together give the solar declination (dec) and (eot). 
  Knowing that the photo is taken somewhere in the general area of Los Angeles 
  tells us the time zone of the location - therefore giving us the central 
  meridian (merid) of the time zone. 
  
  Having supplied these values, we now have an equation in two unknowns: 
  latitude (lat) and longitude (long). Graphically, we can represent this 
  equation by using the magic of television to draw a curve in the sky above all 
  the places whose latitude and longitude satisfy the equation. If we do 
  the same thing for the second photo we obtain a slightly different 
  curve. The two curves will intersect at a single point - directly above 
  the location at which the photos were taken.
  
  The show is likely to come up with some graphic to illustrate these 
  curves in the sky. They went through several versions of dialog and 
  descriptions of the graphics - right up to the day they were shooting the 
  relevant scene, I was trying to talk them out of the idea that the curves 
  would somehow be the links from the shadow to the sun and that they would pass 
  through the sun. I hope they go

The Antikythera Mechanism

Professor Mike Edmunds
Emeritus Professor of Physics, University of Cardiff

What may well be the most extraordinary surviving artifact from the ancient 
Greek world was discovered just over a century ago. Found in 1900 in a wreck 
off the coast of the Mediterranean island of Antikythera, the device contains 
over thirty gear wheels and dates from around 100 B.C. Now known as the 
Antikythera Mechanism, it is an order of magnitude more complicated than any 
surviving mechanism from the following millennium, and there is no surviving 
precursor.

Well there's already a very similar web site
confluence.org/
This is for people trying to stand on points of exact degrees intersecting 
(according to WGS84)
I have stood on two such points   54. N  2. W  (on a lonely bit of 
moorland above Skipton, UK.It's very boggy , be careful ;-) ) and   52 N  5 
E  (Just next to a roundabout near Utrecht in the Netherlands).
Trying to think back to my browsing of the site I don't recall any dial

A more pertinent question might be what dials are on whole number lat / long

So what is required is some coating that absorbs in the radio part of the

  Hello Peter and all,

 Yes, clouds are a significant, perhaps the overwhelming issue with
 sundials. Night knocks out half the time and clouds at least half of the
 remaining daylight hours. Our BSS colleagues know the problem. The most
 common sundial motto is I count only the sunny hours. This is a truly
 defeatist attitude in these days of technology. Can we do better? The
 effects of clouds are subtle. A slight overcast can destroy the contrast
 required to read a sundial. Such sunlight, not enough to cast shadows can
 burn pale skin. Fleeting clouds cause the shadow to bounce back and forth
 giving indeterminate time readings depending on the side of the sun
 obscured. I don't think wavelengths are the solution. Wavelength effects
 giving us red sunsets but there seems to be no advantage through daytime
 clouds. But where there is light, there is hope. Polarization is detectable
 through light clouds. Take that old polarizing filter from your obsolescent
 SLR camera or an old pair of Polaroid sunglasses, hold towards the sun and
 turn to see the polarization of the sky. Direct views of the sun are not
 required. Polarized skylight can tell you where the sun is when it is
 obscured. The polarization effect is evident but not distinct. The
 phenomenon exist and is familiar to photographers with polarizing
 filters, a vanishing species. Has the effect been exploited by gnomonists?
 I don't think so. The opportunity remains, a chimera, like analemmatic
 moondials. I am working on the latter for the NASS conference in Victoria
 BC in June.

Just watching BBC news which is showing (amidst election blather) liberation 
commemorations from Guernsey.  I had a sudden flash back to a BSS journal 
article about a memorial obelisk sundial in St Peter's port with important 
liberation times on May 9th marked out on a curved seat .   I was shocked that 
this was unveiled 20 years ago today (though the journal article may have been

RE: [BSS] New Sundials in Britain

[Ian Maddocks]

[Quick resend - Sorry don't; know what went wrong on formatting of last email, 
Gone to more plain text]
Hi

 

In the BSS Newsletter just published there is a section
about finding new sundials in Britain by looking at#sundial 
on Twitter and Instagram.   This
email is just to save BSS members having to retype links from the printed page.


www.twitter.com/search?q=%23sundial

www.instagram.com/explore/tags/sundial/


I found these nine dials, none of which are in the BSS
Register, in just a few hours looking through images posted over the last few
weeks.   

 

1)Sexby Gardens,
Peckham Rye Park, London, SE15 3UA

A nice new horizontal installed in 2005  when the gardens were refurbished.   
EoT graph included

2)Ada Salter Rose
Garden, Southwark Park, London, SE16 2ET

A largish dial in a public park , built into the paving of a
formal garden, Dated 1936

3)Rose Garden,
Saughton Park,  Edinburgh, EH11 3HP

A frankly rather large column dial with at least three dial
faces.  This defiantly comes into the
category of “How did we miss it?”

4)St Conan’s Kirk,
Loch Awe, On A85, on the way to Oban, PA33 1AL

A horizontal dial with lovely sun design in the gnomon,  Overlooks Loch Awe

5)Sundial Cafe,
Main St, Limekilns, Dumfirmline, KY11 3HG

A vertical dial marked as 1689, On the Main Street

Late breaking news - I’ve subsequently seen another photo on
the web showing this is two dials  - the
South facing dial I had seen +  an East
facing dial around the corner which I missed

6)St Mary
Magdalene Church, Winsford, 
Somerset,  TA24 7JQ

Magnificent horizontal with lots of detail, sadly covered in
moss making reading details very tricky

7)Gawsworth Hall ,
near Macclesfield, Cheshire SK11 9RN

Gawsworth Hall seems to have an old horizontal as well as
the vertical already recorded.

The Register is also missing a photo of the vertical dial
3095 if anyone is visiting this location

8)Flower Garden,
Kennington Park, Kennington, Lambeth, SE11 4BE

Great new slate dial with domed appearance.  Gnomon is made of slate too but 
it’s very
thick.  Now that’s what I call a
noon-gap!

9)Mapperton House,
Mapperton , Dorset, DT8 3NR

So-so looking dial. 
Appears to have no noon gap so unsure of rest of delineation.  Don’t go out of 
your way for this one


I have an electronic (pdf) document of all the dials above
but with the Instagram/Twitter/Google photos included.  For each dial there is 
also a link to Google
or StreetMap to guide you as best as I can manage.   It is available from my 
Google drive at 


http://bit.ly/2b5p32J   



I’ve also created a Google Map with them on


http://bit.ly/2aXDLq5


Of course BSS doesn’t have the rights to any of the
photographs I scrape off the internet.  
We can keep a copy as a record but shouldn’t be including them in the
Register.  Also the technical details are
just whatever you can see and deduce from the photos, not real
measurements.   Please i can encourage
BSS members to get out to see these dials, take photos, record dimensions then
send in a report.

The Newsletter says “If you are a BSS Recorder in the
vicinity of any of the locations please can you check the dials and put in a
proper report for the Register”  but of
course I should have said “Any BSS members in the vicinity of any of the
locations ”. Reports from new
recorders are always welcome.   If you
haven’t put a report in before then there a few guidelines on the BSS website
at

 

http://sundialsoc.org.uk/dials_menu/the-sundial-register/guidelines-completing-form/

 

The recording form is available from the members only area
of the BSS website or from John Foad, the Registrar.

Spotting new dials this way seems a great source of new
sightings!

I had compiled the list above when text for the newsletter
was submitted a few weeks ago.  Since
then I have found many more dials mainly on Instagram and I’ve stopped looking
at Twitter.   As abve they have all been

photos and map links  (10 to 24 , 25 to
46)

The Google map link above already has all the dials in as
new layers.   I hope by putting this
complete list out now we might get some visit reports in whilst it is still
summer 

 

10)Thurnham
Country House B, Castle Hill, Thurnham, nr Bearsted, ME14 3LE

Horizontal set in formal gardens, Classic country house dial

11)The Rookery,
Streatham Common Park, Covington Way, Streatham , London SW16 3BY

A perfectly reasonable standard public park horizontal

12)Cleeve House
Country House B, Trowbridge Rd, Seend, SN12 6PG

Large wall declining dial built high on wall.  It declines and is canted out 
from the wall -
I wonder if has been moved?

Longcase Clock with Equation of TIme

[Ian Maddocks]

hi folks


I was just blundering around the internet when I came across the following that 
may be of interest..


A long case clock from 1730 London that has an annual dial for displaying the 
date and the equation of time

http://www.raffetyclocks.com/antique-clocks/d/antique-month-equation-and-year-calendar-longcase-clock-by-john-topping-london/170271
It's a premade disk with EoT table that rotates in a year, not a P type 
kidney cam, but was new clock complication to me

Re: Longcase Clock with Equation of TIme

[Ian Maddocks]

hi Willy


As is the answer to so many things these days...  There's an app for that

If you have a smart watch you can create your own watch face as you like it 
with underlying code

For example

https://play.google.com/store/search?q=watchmaker=apps=en

shows all the watch-face making apps for android smart watches

I only found one reference to EoT in the G+ forum for the first (WatchMaker) app
(The e-watch was a recreation of a two sided real watch with EoT but they 
didnt' seem to have replicated the second side that had the EoT)
so there's a gap in the market to be plugged!


And in case anyone is interested .  If you want a mechanical watch with EoT 
here's a watch selling site with a search included
http://www.chrono24.co.uk/search/index.htm?query=equation+of+time=true=1
But expect to be paying at least one kidney

As explained by Fred Sawyer in a recent lecture to the British Sundial Society, 
if often worked the other way around... people had an equation table and all 
kinds of rules so that they could adjust their clock so that it matched dial 
time for as long as possible.

Dial time was (and still is for some) 'true' time. The acceptance of local mean 
time was a slow process. Likewise the acceptance of national mean time met with 
a great deal of resistance. In Dorchester in 1858, in the UK, a judge in a 
court case found in favour of the plaintiff, since the defendant was not 
present at 10:00 o'clock when the case was scheduled. The court was using GMT. 
The defendant arrived at 10:00 local mean time - a few minutes late. He 
appealed and the appeal judge ruled...
"Ten o’clock is 10 o’clock according to the Time of the Place and the Town 
Council cannot say that it is not, 
but that it is 10 o’clock by Greenwich 
time. Nor can the time be altered by a railway company.… Nor by any person who 
regulates the clock on the Town-Hall."

Unless you lived in a (maritime) city, or had an astronomer on hand, or a local 
rich man who went up to the city and owned a chronometer, there was NO way to 
set a clock without a Sundial. It all changed with the the arrival of the 
telegraph   I have found that this is something that watch and clock 
enthusiasts sometimes forget!

Sundials on OS maps

[Ian Maddocks]

hi again


And whilst i'm on

Does any know a way of searching OS maps for things other than places or street 
names, specifically the antiquities in Gothic font?   At the conference in 
Liverpool Mike Shaw talked about tracking down a dial from a "SD" on an old 
map.   Whilst checking out an Instagram dial sighting I ended up at the 
following map

http://www.streetmap.co.uk/map.srf?x=376965=671950=115

The Sundial here is BSS Register #1557

My question is does anyone know a method of searching for antiquities?

I doubt there will be any dials we dont' know about, but given the size of some 
of the dials I have found on Instagram i'm not 100%!


Thanks

Re: Precise locations

[Ian Maddocks]

Hi Doug

If you haven't been concentrating I added the W3W address to my signature a few 
months back.
Given the 3 m resolution you actually get a few choices of what address to pick 
for any given plot of land.   frog.happy.froze is actually more my living room 
than front door.   I wandered the cursor around till I found the most memorable 
three words

At the moment if you want to navigate by W3W the NavMii free mobile sat nav app 
(using OpenStreetMap data) understands the addresses.
https://play.google.com/store/apps/details?id=com.navfree.android.OSM.ALL
in the descriptions says   "Local Place search (powered by TripAdvisor, 
Foursquare and What3Words)"

The other site that uses them is www.streetmap.co.uk.For those of us dial 
recorders who want to have a location converted to multiple formats as easily 
as possible the "Click here to convert coordinates" under the maps is 
invaluable, and includes the W3W reference on the last line   see 
http://www.streetmap.co.uk/idgc.srf?x=538955=177217 for example

I have been told of another method called what3words.com<http://what3words.com>

Designed in 2013 and developed since then, it uses a grid of the world made up 
of 57 trillion squares of 3 metres by 3 metres. Each square has been given a 
3-word address. what3words has named the 17 trillion squares on land with 3 
words in 10 other languages in addition to English. Of potential value to less 
developed countries.  My contact says:  "A very good idea I think as it is 
easier than numbers and covers the whole globe (dependent of course on the w3w 
database continuing to exist, which let's hope it does) to give e.g. addresses 
in African shanty towns or remote villages in India as well as where there are 
postcodes."

An intriguing system, based on the fact that three words, however unrelated, 
are rather more memorable than a latitude/longitude. Typing Greenwich 
Observatory comes up with oval.blast.improving. My house has a similar unique 
set of words.

Well worth a look.

As far as physical 'products' are concerned, these days they would
probably have a "QRcode" - you know, one of those small square blocks
which just seem to contain a 'jumble' of black and white pixels.

Those are mainly used to direct people straight to a website, but
they can contain a lot more information (if you needed to do so).


If you want to include an actual geographical location, then one of
the best ways is to use a "NAC code" - which stands for 'Natural Area
Coding' also known as Universal Map Coding, or a Universal Address).

It is usually included as a 'meta', within any website design coding.


For sundial-related subjects, the only people I know that use these
methods are "Modern Sunclocks" - and (if anyone is interested), I
have 'attached' the QRcode they use to drive people to their website.

Within the 'meta' code of that website they also display a NAC code,
so that any people can find-out their exact Latitude and Longitude.


Sincerely,

Martina Addiscott

Re: Precise locations

[Ian Maddocks]

Hi Michael

Yes in the western world the 3m resolution either allows for a bit of fun, or 
nice precision.  I have hovered over all of the squares covering my flat and 
picked the most memorable to tell visitors (it's in my living room), how ever 
if this system caught on i would definitely pick the w3w for the front door to 
our block to tell delivery folk (the sign that says "flats 1-9" is too small to 
be easy read from the road).   But yes the living room address location is the 
same for my upstairs and downstairs neighbours

Seasons greetings

Thanks for the explanation. That answers both of my questions.

Easier to remember, and less-likely for someone to mis-write one of the 
characters. I can see where there are applications where those qualities would 
be helpful.

A lot of houses & cottages already have names, and so wouldn't it be good for 
people to be able to request that the square containing their front-door have 
the name of their house, if that word-combination (or something too close to 
it) isn't already in use?

Thanks again.

Hi Michael

From reading the web site, as I understand it, they have chosen the words from 
a big dictionary file.  The interesting points were that they deliberately 
choose smaller words for built up areas, going to larger words elsewhere on 
landmass and the biggest words out to sea.   This was to make the most likely 
to be used combinations shorter and more memorable.  They also filtered out all 
the rude words.   They have also taken the trouble to ensure that similar 
groups of words are no where near each other.  If you try hovering over the map 
and looking at each square the words from one square to the next are quite 
different. If you go to their map and type in two or two and a half words till 
the suggestions come up you will see that similar suggestions (maybe one ends 
in a plural) are nowhere near each other to make typos obvious.  Another 
feature is that different languages are not just translations of the base 
English, in case words are longer or more easily confused on the other 
languages.   I haven't seen what grid the system is based on ,though i presume 
standard 1984 Sat nav.

Why?  Will their main aim was to give accurate easy mapping to places without 
road names or post codes.  Even our post codes are only accurate to 100 m or so 
but the situation is worse in less developed places. If you live in an over 
crowded place you can still give an accurate address really easily.   If your 
delivery driver was using free open source map from Navmii (sp?) , formerly 
Open Street Map he should be able to find you to 3m. It's free mapping on your 
phone that understands w3w.   Also the web site 
streetmap.co<http://streetmap.co> uk does.
This is their target market.  They don't expect you to radio the coast guard 
with your coordinates in this format!

It's more accurate than a post code , and easy to remember compared to lat and 
long to the same accuracy.

Merry Christmas

Re: Precise locations

[Ian Maddocks]

Hi Michael

From reading the web site, as I understand it, they have chosen the words from 
a big dictionary file.  The interesting points were that they deliberately 
choose smaller words for built up areas, going to larger words elsewhere on 
landmass and the biggest words out to sea.   This was to make the most likely 
to be used combinations shorter and more memorable.  They also filtered out all 
the rude words.   They have also taken the trouble to ensure that similar 
groups of words are no where near each other.  If you try hovering over the map 
and looking at each square the words from one square to the next are quite 
different. If you go to their map and type in two or two and a half words till 
the suggestions come up you will see that similar suggestions (maybe one ends 
in a plural) are nowhere near each other to make typos obvious.  Another 
feature is that different languages are not just translations of the base 
English, in case words are longer or more easily confused on the other 
languages.   I haven't seen what grid the system is based on ,though i presume 
standard 1984 Sat nav.

Why?  Will their main aim was to give accurate easy mapping to places without 
road names or post codes.  Even our post codes are only accurate to 100 m or so 
but the situation is worse in less developed places. If you live in an over 
crowded place you can still give an accurate address really easily.   If your 
delivery driver was using free open source map from Navmii (sp?) , formerly 
Open Street Map he should be able to find you to 3m. It's free mapping on your 
phone that understands w3w.   Also the web site streetmap.co uk does.
This is their target market.  They don't expect you to radio the coast guard 
with your coordinates in this format!

It's more accurate than a post code , and easy to remember compared to lat and 
long to the same accuracy.

Merry Christmas

Two things that I ask someone to explain:

1. How does the 3-word position-designation work? Aside from the names of the 
positions, what is the co-ordinate system? Latitude & longitude? How are the 3 
words chosen for each of the 3 meter by 3-meter locations?

2. What's wrong with latitude & longitude?

I have been told of another method called what3words.com<http://what3words.com>

Designed in 2013 and developed since then, it uses a grid of the world made up 
of 57 trillion squares of 3 metres by 3 metres. Each square has been given a 
3-word address. what3words has named the 17 trillion squares on land with 3 
words in 10 other languages in addition to English. Of potential value to less

easier than numbers and covers the whole globe (dependent of course on the w3w

Dickens' sundial

[Ian Maddocks]

Hello Diallists


Whilst trawling Instagram #sundial i found this, asking for info about a dial 
once belonging to Charles Dickens.  Can anyone help them?

There's a drawing and photo provided in the link below

dickensmuseum<https://www.instagram.com/dickensmuseum/>The Missing Sun-Dial
**
The sun-dial stood 4ft 8in high, in the garden at Gad’s Hill (Dickens's final 
home) in a most prominent position as it was considered one of Dickens's most 
valuable treasures.
*
After Dickens’s death [in 1870], it was bought by Mr. Crighton, of Rochester. 
Alice Morse Earle, in her 1902 book Sundials and Roses of Yesterday, says that 
the dial was later sold in London for the sum of £50. An article in the 
Pittsburg Press, 14 February 1899, gives more details “There is offered for 
sale by a curiosity dealer in London the old sun-dial and stone column formerly 
the property of Charles Dickens.’ In 1907 it was exhibited in the ‘Pickwick 
exhibition’ in London, and had been lent by the company Francis Barker sundial 
and barometer specialists, 12 Clerkenwell Road, London. The company was also 
making replicas of the original to sell.

As we continue our search, let us know if you can shed any light on the 
mysterious whereabouts of the sundial.

Hi Jack and Michael,



I don’t agree. The concept is very simple. Perhaps you have had bad teachers. 
One of my presentations at the upcoming conference is a purely grapghical 
method of designing an analemmatic sundial. No trig, not even geometry other 
than the Greek’s ruler and string or a simple math set with ruler, protractor 
and a compass.  From this graphical technique comes a whole new concept by  
Chris Lusby Taylor for seasonal makers that I will describe at the conference 
next month.



To demonstrate the simple concepts for analemmatic sundials, start with this 
experiment as a class activity, hands on and interactive. Cut out a circle of 
cardboard. Stick a pencil through the center at a right angle to the disc. Hold 
it with the pencil vertical. Look straight down on the disc, a circle true 
size. Hour angles drawn every 15° would also be true angles. The pencil is seen 
as a point. Now physically drop the disc and pencil onto a horizontal table. 
Get down to view across the table and turn the disc to see it on edge. It will 
be seen as a true length straight line equal to the diameter of the circle. The 
pencil will also be seen a true length line. If you chose the right length of 
pencil, the pencil will make an angle to the horizontal equal to your latitude. 
The disc will make an angle to the co-latitude.  Now get up and look straight 
down on the disc and pencil on the table. The disc will be seen as an ellipse 
and the pencil as a shorter line as neither disc or pencil are true length. 
Look at it straight down from above and mark the point on the desk that is 
directly under the end of the hour mark on the disk starting with the disc 
turned to the starting point noon being directly under the pencil. These points 
define. the hour ellipse for an analemmatic sundial.



Next the enigmatic date line. Consider the sun shining down at noon at any day 
of the year onto the pencil through the disc on the table. The sun shines down 
on the pencil and there is a unique point on the pencil each day where the sun 
at noon shines directly onto the rim of the disc. At the summer solstice the 
sun is high in the sky. The angle of the suns ray down to the disc rim is at an 
angle of 23.5° to the disc. At the winter solstice the angle is -23.5 ° On the 
spring and fall equinox the angle is 0°. Every day has a different angle, the 
solar declination for that day. Now you could switch to ruler and protractor 
marking on paper right angle  triangles with the base equal to the disc radius. 
Measure angles from the base point up at the chosen declination angle and draw 
a line at that angle to the line at right angles to the other end of the base 
line for the declination points for the chosen dates. Now draw a line for the 
horizon at an angle to the disc base line equal the latitude. Draw lines 
perpendicular to the horizon line to the chosen declination date points.  The 
points on the horizon line are the points where you stand on the analemmatic 
sundial.



In one class activity session all the kids with a good teacher could make their 
own analemmatic sundial based on these simple concepts. It involves simple 
tools  from the standard geometry set and a simple concept of looking at a 
circular disc with a rod through the center from different points of view.



The general problem is that sundials are not on the curriculum for any school 
boards. Teachers teach to the curriculum. The few teachers I have met in NASS 
are excellent but there are very few others are interested in such an 
extracurricular activity. Perhaps that is the value of a analemmatic sundial 
installation at a school would be to stimulate interest.

I very much agree with this.  In fact, at the risk of sounding stupid, I have 
to confess that I don’t have an intuitive grasp of how an analemmatic dial 
works.  Yes, I have at various times gone through the explanation, but it does 
not stick in any way that I can mentally attach to the plane of the earth’s 
surface and the motion of the celestial sphere.  I know I could review the 
geometry and remember it if I tried but agree that the geometrical projecti
