I'm surprised this is still standing, even though it's listed. There have been a lot of "Listed" buildings in Newham that have been demolished in the dname of progress. But no one seems bothered.........

"state that they hold certain isles in the sea between Cornwall and Ireland, of which the largest is called Scilly, to which ships come passing between France, Bretagne, Galithia, Bayonne, Gascony, Scotland, Ireland, Wales and Cornwall:

and, because they feel that in the event of a war breaking out between the kings of cELTIC bRITAIAN and France, or between any of the other places mentioned, they would not have enough power to do justice to these sailors, they ask that they might exchange these islands for lands in Devon, saving the churches on the islands appropriated to them."

Meniscus Systems

a variety of optical catadioptric systems in which a spherical (or, less frequently, an elliptical) mirror, or a system of mirrors and lenses, is preceded by one or more achromatic menisci. Meniscus systems were invented in 1941 simultaneously and independently by D. D. Maksutov and D. Gáabor. Meniscus systems use meniscus lenses with surfaces that have nearly the same radii of curvature. Lenses of this type are compensators; that is, they have little effect on the general direction of the rays but appreciably change the distortions (aberrations) of optical images of the optical systems of which they are a part.

A meniscus is nearly achromatic (that is, it is free from chromatic aberration) with respect to a parallel pencil of rays if the

quantity (R1 — R2)/d is close to 0.6, where R1 and R2. are the radii of curvature of the meniscus surfaces and d is the thickness of the meniscus (see Figure 1 ,a and b). At the same time, R1 and R2 may be selected such that the negative spherical aberration of the mirror (mirrors) is compensated by the positive spherical aberration of the meniscus. The coma in a meniscus system depends on the distance between the meniscus and the mirror, and at a certain position of the meniscus the coma is equal to zero. The astigmatism of the simplest meniscus systems is low. The curvature of the image field in a meniscus system is significant. For this reason, photography in these systems is performed on appropriately curved photographic film. However, the use of an additional corrective Piazzi-Smyth lens, which corrects the curvature of the field as well as the distortion, makes it possible to perform photography using meniscus systems on flat plates and films. Single-meniscus systems with high aperture ratios exhibit low chromatic aberration, which is known as chromatism of magnification. This effect is eliminated by using a pair of oppositely oriented menisci (Figure 2,a, b, and c). The same goal is attained in other cases by a light retouching of one of the surfaces of the

Practical applications in astronomy include meniscus systems in telescopes (which are also called Maksutov telescopes), schematically represented in Figure 3. The first scheme (Figure 3,a) provides adequate field of view (up to 5°) and aperture ratio (up to 1:1.2). The second scheme (Figure 3, b), which is the meniscus analog of the Cassegrain reflector system, provides a moderately large field of view (of the order of 1°) at a long focal length and, therefore, at a lower aperture ratio (1:10 to 1:15). The third scheme (Figure 3,c), which is the meniscus analog of a Gregorian reflector system (telescope), resembles the second scheme in its features.

Cassegrain-type meniscus systems are used in photographic objectives of long focal length. The shortness of these objectives for a relatively large diameter of the entrance pupil gives them an important advantage over telephoto lenses.

Meniscus systems are more compact than other optical systems with comparable parameters, which simplifies the control of meniscus telescopes by clockworks. Their principal surfaces are of a simple form (spherical), which simplifies manufacture and permits precise optical control of the meniscus systems. Correction of all the principal aberrations leads to high-quality images not only in the center of the field of view but also at the edges of large fields of view

The long blue days, for his head, for his side, and the little paths for his feet, and all the brightness to touch and gather. Through the grass the little mosspaths, bony with old roots, and the trees sticking up, and the flowers sticking up, and the fruit hanging down, and the white exhausted butterflies, and the birds never the same darting all day long into hiding. And all the sounds, meaning nothing. Then at night rest in the quiet house, there are no roads, no streets any more, you lie down by a window opening on refuge, the little sounds come that demand nothing, ordain nothing, explain nothing, propound nothing, and the short necessary night is soon ended, and the sky blue again all over the secret places where nobody ever comes, the secret places never the same, but always simple and indifferent, always mere places, sites of a stirring beyond coming and going, of a being so light and free that it is as the being of nothing.

The term "Archeometre" originates from the Greek and means "the measure of the principle". The system refers also to a series of symbols and meanings, which refer to the federal drawer.

'Archeometre' is it the measurement of the 'Archee' (Universal Cosmic Force) of which the Hermetists speaks. Is it a process, a 'key' which makes it possible to penetrate the Mysteries of the Word. It is a measuring instrument of the first (primary) principles of the manifested universe.

Alexandre Saint Yves d'Alveydre's Archeometre shows the original Atlantean alphabet translates into the material the word, form, color, smell, sound and taste, the key to all religions and the sciences of antiquity.

The Archeometre is represented by a circle, which has two scales from 0 to 360 degrees and 360 degrees to 0. It is divided into 12 ranges with 30 degrees each. In the individual ranges are drawn in the tierkreiszeichen, planet, colors, tones and the letters of different alphabets.

The Archeometre is a universal canon (guide), which wants to point the relationship out between the astrological indications, tones, smells, letters and colors. The musician finds therein the color of tones, the writer the toncharakter of letter etc. The Archeometre is to also point practical use out that the religions, arts and architecture a synthesis from different ranges to form.

ON the beach at night alone,
As the old mother sways her to and fro, singing her husky song,
As I watch the bright stars shining—I think a thought of the clef of the universes, and of the future.

A VAST SIMILITUDE interlocks all,
All spheres, grown, ungrown, small, large, suns, moons, planets, comets, asteroids, 5 All the substances of the same, and all that is spiritual upon the same,
All distances of place, however wide,
All distances of time—all inanimate forms,
All Souls—all living bodies, though they be ever so different, or in different worlds,
All gaseous, watery, vegetable, mineral processes—the fishes, the brutes, 10 All men and women—me also;
All nations, colors, barbarisms, civilizations, languages;
All identities that have existed, or may exist, on this globe, or any globe;
All lives and deaths—all of the past, present, future;
This vast similitude spans them, and always has spann’d, and shall forever span them, and compactly hold them, and enclose them. 15

The gallery and Cornwall county council, which owns the site, insist the creative centre is crucial to make Tate St Ives sustainable. They argue that the gallery has been so successful, attracting three times the expected number of visitors, that too great a strain is being put on the existing building.

But Pete Dale, campaigns officer for Keep St Ives Special, said the new development would ruin views across the ocean from St Ives and spoil a vista of the town as walkers approached it, as well as taking valuable parking spaces. Mr Dale, who runs a bed and breakfast close to the proposed site, said: "We're not against the Tate. But if they need to expand, there are alternative sites."

Edward Jenkyn, 72, a carpenter who has lived in St Ives all his life, said: "I think they are getting too big for their boots and have stopped listening to us."

In the 1920s an artists' colony was founded in the town, and at the start of the second world war the likes of Ben Nicholson and Barbara Hepworth settled in St Ives, establishing an outpost for the avant garde. After the war, a younger generation emerged there, including Terry Frost and Patrick Heron. The original idea of setting up a world class gallery was to house the work of the St Ives School. But as the project developed, it was decided that a wider range of work ought to be shown.

But Toni Carver, editor of the St Ives Times and Echo, said the artistic community had always had to work hard to keep the town on its side. "The Tate has stopped relating to the area," he said.

David Shalev, one of the architects who designed the original building, said: "I think the philosophy was to make it in scale with artists' studios. To double the size would make it out of scale."

Positioned obtrusively on the headland this house seems devoid of any historical or scientific reasons for marring an otherwise beautifully untouched headland, located on an unspoiled stretch of coast between Porthleven and Praa Sands; with views to the Lizard to the east and across to Lands End to the west. The house perches on the edge of Rinsey Head and sits in grounds of approximately 30 acres! Rinsey Head was built in the early twentieth century and is architecturally designed to maxmise the views in every direction (presumably when planning rules were even more opaque than contemporanously) alternatively depending on your perspective, one cannot be spared the constant reminder that yet another feature of Cornwalls natural history has been conquered and colonised.

Rinsey Head is advertised as a comfortably appointed, spacious holiday home and film location.

June 6th 2012 is the date of the second recent transit of Venus, metalurgically Venus is represented by the metal Copper found in large quantities around Perranuthnoe. Many forecasts and revelations are linked to this astronomical phenomena and chief among these is the Mayan calender; In the finest of the early Mayan books, the Dresden Codex, the beginning of the Great Cycle in August, 3114 BC is referred to as the "Birth of Venus". As well, several of the surviving Mayan manuscripts also refer to Venus as a Sister Planet of Earth. And Mayan prophecy states that the renewed world of new consciousness will be born on the occasion of the Venus Passage across the Sun of 6th June 2012. The Mayans had also been able to determine the exact timing between Venus passages to the number - 583.92 days. Without fine optical observation instruments, how were Mayan astrologers able to discern such an exact timing? There has to be a reason why they put so much into this cycle.

They also knew there was a link between the time Venus takes to revolve on its axis, Earth timing and the years between Venus passages across the face of the Sun. There are 243 years between a pair of passages and thus the Earth will have revolved 243 times around the Sun, while Venus has revolved on its own axis 365 times - which is the length of time in days that the Earth revolves around the Sun. The cross-links are amazing and known to the Mayans for several thousand years.

The eight years that pass between each occultation are fecund processing moments for new ideas and world change. Previous cycles show that global communications and a shift in consciousness regarding the scope and nature of the world are all part of these transits. The other focus is Venus's role as female entity and ruler of the feminine, the creative and as an artistic channel for new breakthroughs.

The plural of "tessera", a name given to piece used in a mosaic. Originally tesserae were the cubes of stone used in ancient classical mosaics, but now the term is used for pieces of any kind of mosaic material, whether they are ceramic, stone, pebbles, glass or some other substance.
