I've made a clay charm necklace of a character from my analog horror. sometimes one should be a little bit autistic about their own media as well.

[alphynix]

Angelosaurus dolani was an early synapsid, part of the caseid family and closely related to the more well-known Cotylorhynchus.

Living in what is now Texas, USA during the mid-Permian, about 270 million years ago, it's only known from partial skeletal remains but was probably around 3m long (~10').

Like other large herbivorous caseids it would have had a tiny head with proportionally big nostrils, a short neck, a large barrel-shaped body accommodating a voluminous gut, a long tail, and strong sprawling limbs. But compared to its relatives Angelosaurus was particularly bulky, with shorter thicker heavily-muscled limbs and stubbier digits ending in broad hoof-like claws.

In closely related caseids the presence of teeth on the roof of the mouth and a well-developed hyoid apparatus suggests these animals had big tough tongues, which may have been used to mash mouthfuls of plant matter against the palatal teeth to partially break it up before swallowing.

Based on skin impressions from other early synapsids, Angelosaurus probably had crocodilian-like scutes on some parts of its body – likely on its underside and tail, and maybe also on the top of the head as indicated by the pitted bone texture of caseid skulls – but whether the rest of its skin was scaly or naked and glandular is currently unknown.

In recent years there have also been some proposals that large caseids may have had a semiaquatic hippo-like ecology, but this idea is controversial.

According to the Riparian law, the sword, the spear, and the iron armor of a warrior attained the value of at least twenty-five cows, or two years of a freeman’s labor. A cuirass alone was valued in the Salic law (Desmichels, quoted by Michelet) at as much as thirty-six bushels of wheat.

[162] It is permissible to think that this conception (related to the conception of tanistry) played an important part in the life of the period; but research has not yet been directed that way.

[163] It was distinctly stated in the charter of St. Quentin of the year 1002 that the ransom for houses which had to be demolished for crimes went for the city walls. The same destination was given to the Ungeld in German cities. At Pskov the cathedral was the bank for the fines, and from this fund money was taken for the wails.

[166] Thirty-six times more than a noble, according to the Anglo-Saxon law. In the code of Rothari the slaying of a king is, however, punished by death; but (apart from Roman influence) this new disposition was introduced (in 646) in the Lombardian law — as remarked by Leo and Botta — to cover the king from blood revenge. The king being at that time the executioner of his own sentences (as the tribe formerly was of its own sentences), he had to be protected by a special disposition, the more so as several Lombardian kings before Rothari had been slain in succession (Leo and Botta, l.c., i. 66–90).

[169] If I thus follow the views long since advocated by Maurer (Geschichte der Städteverfassung in Deutschland, Erlangen, 1869), it is because he has fully proved the uninterrupted evolution from the village community to the medieval city, and that his views alone can explain the universality of the communal movement. Savigny and Eichhorn and their followers have certainly proved that the traditions of the Roman municipia had never totally disappeared. But they took no account of the village community period which the barbarians lived through before they had any cities. The fact is, that whenever mankind made a new start in civilization, in Greece, Rome, or middle Europe, it passed through the same stages — the tribe, the village community, the free city, the state — each one naturally evolving out of the preceding stage. Of course, the experience of each preceding civilization was never lost. Greece (itself influenced by Eastern civilizations) influenced Rome, and Rome influenced our civilization; but each of them begin from the same beginning — the tribe. And just as we cannot say that our states are continuations of the Roman state, so also can we not say that the mediæval cities of Europe (including Scandinavia and Russia) were a continuation of the Roman cities. They were a continuation of the barbarian village community, influenced to a certain extent by the traditions of the Roman towns.

[173] See the excellent remarks of Mr. G.L. Gomme as regards the folkmote of London (The Literature of Local Institutions, London, 1886, p. 76). It must, however, be remarked that in royal cities the folkmote never attained the independence which it assumed elsewhere. It is even certain that Moscow and Paris were chosen by the kings and the Church as the cradles of the future royal authority in the State, because they did not possess the tradition of folkmotes accustomed to act as sovereign in all matters.

Sémichon (La paix et la trève de Dieu, 2 vols., Paris, 1869) has tried to represent the communal movement as issued from that institution. In reality, the treuga Dei, like the league started under Louis le Gros for the defense against both the robberies of the nobles and the Norman invasions, was a thoroughly popular movement. The only historian who mentions this last league — that is, Vitalis — describes it as a “popular community” (“Considérations sur l’histoire de France,” in vol. iv. of Aug.

[185] Upon the position of women in guilds, see Miss Toulmin Smith’s introductory remarks to the English Guilds of her father. One of the Cambridge statutes (p. 281) of the year 1503 is quite positive in the following sentence: “Thys statute is made by the comyne assent of all the bretherne and sisterne of alhallowe yelde.”

[186] In mediæval times, only secret aggression was treated as a murder. Blood-revenge in broad daylight was justice; and slaying in a quarrel was not murder, once the aggressor showed his willingness to repent and to repair the wrong he had done. Deep traces of this distinction still exist in modern criminal law, especially in Russia.

[187] Kofod Ancher, l.c. This old booklet contains much that has been lost sight of by later explorers.

[188] They played an important part in the revolts of the serfs, and were therefore prohibited several times in succession in the second half of the ninth century. Of course, the king’s prohibitions remained a dead letter.

[189] The mediæval Italian painters were also organized in guilds, which became at a later epoch Academies of art. If the Italian art of those times is impressed with so much individuality that we distinguish, even now, between the different schools of Padua, Bassano, Treviso, Verona, and so on, although all these cities were under the sway of Venice, this was due — J. Paul Richter remarks — to the fact that the painters of each city belonged to a separate guild, friendly with the guilds of other towns, but leading a separate existence. The oldest guild-statute known is that of Verona, dating from 1303, but evidently copied from some much older statute. “Fraternal assistance in necessity of whatever kind,” “hospitality towards strangers, when passing through the town, as thus information may be obtained about matters which one may like to learn,” and “obligation of offering comfort in case of debility” are among the obligations of the members (Nineteenth Century, Nov. 1890, and Aug. 1892).

[190] The chief works on the artels are named in the article “Russia” of the Encyclopædia Britannica, 9th edition, p. 84.

[191] See, for instance, the texts of the Cambridge guilds given by Toulmin Smith (English Guilds, London, 1870, pp. 274–276), from which it appears that the “generall and principall day” was the “eleccioun day;” or, Ch. M. Clode’s The Early History of the Guild of the Merchant Taylors, London, 1888, i. 45; and so on. For the renewal of allegiance, see the Jómsviking saga, mentioned in Pappenheim’s Altdänische Schutzgilden, Breslau, 1885, p. 67. It appears very probable that when the guilds began to be prosecuted, many of them inscribed in their statutes the meal day only, or their pious duties, and only alluded to the judicial function of the guild in vague words; but this function did not disappear till a very much later time. The question, “Who will be my judge?” has no meaning now, since the State has appropriated for its bureaucracy the organization of justice; but it was of primordial importance in mediæval times, the more so as self-jurisdiction meant self-administration. It must also be remarked that the translation of the Saxon and Danish “guild-bretheren,” or “brodre,” by the Latin convivii must also have contributed to the above confusion.

An aperiodic tiling discovery

Much excitement last week with the publication by David Smith, Joseph Myers, Craig Kaplan and Chaim Goodman-Strauss of their discovery of a single tile which tiles aperiodically. Not only that but it does not need any supplementary rules, as Penrose's dart/kite pair do, to ensure aperiodicity. Christian Lawson-Perfect wrote about the story in aPeriodical. Later: There is now an excellent online talk by Craig and Chaim on the discovery and its proof hosted by the National Museum of Mathematics in New York.

The shape was discovered by David Smith, a hobbyist geometer. There is a wealth of research in David's blog, which starts with the declaration "I am not a mathematician but I do like shapes, interesting symmetry, polyhedra, tessellations and geometric patterns. " Skimming though it, one can see the deep exporation of shapes which makes his discovery seem almost inevitable. I plan to read more of his blog for inspiration. Well done ye, David!

The mathematical work of proving that the tile is aperiodic is a masterful exercise, clearly explained. A truly inspiring collaboration between a tinkerer, acedemic mathematicians and computer scientists.

OpenSCAD

Naturally I had a look at this with my OpenSCAD tiling tools.

tl:dr: A customizer on Thingiverse.allows both kinds of tiles in normal or mirror forms and all intermediate tiles to be printed or laser-cut.

I began by defining the perimeter as a sequence of sides each defined by side length and interior angle taken from the diagram, where we see up of 16 right triangular segments ( 8 kites) of adjacent hexagons. In this formulation, r is the long side of the triangle, a and b the other sides.

function hat_peri(r) = // r is the radius of the base hexagon // returns perimeter as a sequence of [side length,internal angle]    let (a = r * sin(60), b = r*cos(60) )    [[b,180],[b,120],[b,270],[a,120],[a,90],[b,120],[b,270],[a,120],     [a,90],[b,240],[b,90],[a,240],[a,90],[b,120]];

The first two sides form a straight line but for the purposes of tiling are distinct edges.

The perimeter is converted to a sequence of points using turtle-like geometry:

function peri_to_points(peri,pos=[0,0],dir=0,i=0) =     i == len(peri)       ? [pos]       : let(side = peri[i])         let (distance = side[0])         let (newpos = pos + distance* [cos(dir), sin(dir)])         let (angle = side[1])         let (newdir = dir + (180 - angle))         concat([pos],peri_to_points(peri,newpos,newdir,i+1))      ;

Tiling with this shape requires the use of the mirror image of the base tile:

function reverse(l) = [for (i=[1:len(l)]) l[len(l)-i]];

function mirror_peri(q) = let(p=reverse(q)) [for (i=[0:len(p)-1]) [p[ (i - 1 + len(p) ) %len(p)].x,p[i].y] ];

[This is a bit of a pity. Penrose's tiles are symmetric so the question doesnt arise but the search continues for a monotiling which does not require the use of reflections.]

My library of OpenSCAD functions supports the creation of tilings by defining a sequence of edge-to-edge placements. ATM this list is created manually. Each line specifies the alignment of one of the base tiles and edge to a tile and edge in the assembly.

hat_assembly_6 = [ [[0,0]] ,[[0,0],[0,1]] ,[[0,5],[0,2]] ,[[0,3],[0,4]] ,[[0,13],[0,6]] ,[[1,1],[0,9]] ,[[0,7],[0,12]] ];

module hat_tile_6(d) { p = hat_peri (10,d); t=peri_to_points(p); m=peri_to_points(mirror(p)); unit=group_tiles([t,m],hat_assembly_6); fill_tiles(unit,["red","green","blue","yellow","pink","black","coral"]); }

Parametric tiles

More amazingly still, this tile turns out to be one of a family of aperiodic tiles, which in the limit are simple periodic tiles. They are beautifully animated here. The parametric perimeter description enables all members of this family to be constructed:

function hat_peri_family(r,d) = // r is the radius of the base hexagon

// d is the angle which varies from 0 to 90 // returns perimeter as a sequence of [side,internal angle] let (a = r * sin(d), b = r * cos(d) ) [[b,180],[b,120],[b,270],[a,120],[a,90],[b,120],[b,270],[a,120], [a,90],[b,240],[b,90],[a,240],[a,90],[b,120]]);

At the limits , the tiles tesselate:

d=0 (nicknamed the comet)

d=45

d=90 (nicknamed the chevron)

All the tiles inbetween are aperiodic:

The Turtle

David also discovered a second tile he called the turtle. Defined as a perimeter, this also has 14 sides and is a family of tiles:

function turtle_peri(r,d) = // r is the radius of the base hexagon // returns perimeter as a sequence of [side,internal angle] let (a = r * sin(d), b = r * cos(d) ) [[a,240],[a,90],[b,240],[b,90],[a,120],[a,180],[a,120],[a,270],[b,120],[b,90],[a,120],[a,270],[b,120],[b,90]];

d=60

The periodic endpoints d=0 and d=90 are the same as for the hat.

This is a small section of a tiling in David's blog:

No mirroed tiles in this example.

turtle_assembly_6 = [ [[0,0]] ,[[0,12],[0,13]] ,[[0,13],[0,2]] ,[[0,5],[0,6]] ,[[0,4],[0,7]] ,[[0,5],[0,10]] ,[[0,10],[0,11]] ];

To do

I'd like to add a couple of the suggested decorations.

A big task is to automate the tile placement to construct an assembly. Craig's software does this so I dont expect it to be easy! The approach I'd like to explore (perhaps it's the obvious appraoch?) is to start with the perimeter description of the base tile and extend this as each tile is added. The next tile can be placed by matching a subsequence of the tile perimeter to a subsequence of the expanding perimeter. Bit complicated to ensure that such a match will result in a fit especially with concave shapes.

Further

Veritasium has a nice youtube on the background to aperiodic tiling

Jaap Scherphuis created the PolyForm Puzzle software which was used by David in his explorations.

As you ask, the relevant bit re: Bottom (who is shown as this implies to be a talented speaker, another thing Shakespeare often does with characters who the audience wouldn't expect to be educated)

"In terms of the verse form Bottom uses, again rhyme is used to highlight the formal occasion of his speeches – because it rhymes so persistently and so repetitively, it is stylistically bracketed off from the surrounding dialogue. The first part of his speech (ll.266-69) takes the form of a four-line quatrain rhyming Abab in iambic pentameter. But the second part of his speech (ll.270-80) moves into very short, chiming lines where rhyme in effect overwhelms all other stylistic features. As Holland notes, Bottom uses a version of the ‘“eight and six”’ metre Quince mentions earlier (in Shakespeare, 2008, p. 246); I can show you what this means by relineating part of this passage:

    But stay, O spite! But mark, poor knight,

        What dreadful dole is here?

    Eyes do you see? How can it be?

        O dainty duck, O dear!

The form used here is once again one of the most popular poetic forms of the Elizabethan period, where an eight-syllable line, usually with four stresses, is followed by a six-syllable line, usually with three stresses. Thus in the first ‘line’ above, you get a very predictable iambic sing-song: ‘But stay, O spite! But mark, poor knight’. Shakespeare’s audiences would have been familiar with this form from both popular ballads and the psalms which they sang in church."

[Brown, R. D. (2020) Shakespeare’s language]

Absolutely fucking fascinating tbh.

oooooh thank you cecil!

France, Conseil d'État, 9ème - 10ème chambres réunies, 29 novembre 2024, 494063

https://justifiable.fr/?p=2041 https://justifiable.fr/?p=2041 #10ème #9ème #chambres #Conseil #dÉtat #France #novembre #réunies Vu la procédure suivante : Le préfet du Nord a demandé au tribunal administratif de Lille d’annuler l’élection de Mme G… A… au conseil municipal de la commune de Douchy-les-Mines (Nord) et de proclamer M. C… H… élu à ce conseil municipal. Par un jugement n° 2402148 du 23 avril 2024, ce tribunal a rejeté sa demande. Par une ordonnance n° 24DA00792 du 6 mai 2024, la présidente de la cour administrative d’appel de Douai a transmis au Conseil d’Etat, en application de l’article R. 351-2 du code de justice administrative, la requête d’appel, enregistrée au greffe de cette cour le 24 avril 2024, formée par M. H… contre ce jugement. Par cette requête et un mémoire en réplique, enregistré au secrétariat du contentieux du Conseil d’Etat le 10 juin 2024, M. H… demande au Conseil d’Etat : 1°) d’annuler ce jugement ; 2°) d’annuler l’élection de Mme A… au conseil municipal de la commune de Douchy-les-Mines ; 3°) de le proclamer élu au conseil municipal de cette commune ; 4°) de mettre à la charge de Mme A… la somme de 3 500 euros au titre de l’article L. 761-1 du code de justice administrative. Vu les autres pièces du dossier ; Vu : – le code électoral ; – le code général des collectivités territoriales ; – le code de justice administrative ; Après avoir entendu en séance publique : – le rapport de M. Lionel Ferreira, maître des requêtes, – les conclusions de Mme Céline Guibé, rapporteure publique ; La parole ayant été donnée, après les conclusions, à la SCP Rocheteau, Uzan-Sarano et Goulet, avocat de M. H…, et à la SCP Boulloche, Colin, Stoclet et associés, avocat de la commune de Douchy-les-Mines ; Considérant ce qui suit : 1. Il résulte de l’instruction qu’à l’issue des opérations électorales qui se sont déroulées le 15 mars 2020 pour le renouvellement du conseil municipal de la commune de Douchy-les-Mines (Nord), commune de plus de 1 000 habitants, la liste conduite par M. F… I…,  » Douchy au cœur avec passion « , a obtenu vingt-sept sièges sur les trente-trois que compte ce conseil. A la suite de la démission de Mmes K… L… et Florence Carboulet, ont été appelées à siéger au conseil municipal Mme D… J…, vingt-huitième inscrite sur cette liste, et, compte tenu de la démission de M. E… B…, vingt-neuvième inscrit, Mme G… A…, trentième inscrite sur la même liste. La proclamation de leur désignation a été rendue publique par la mention de leur nom dans le tableau du conseil municipal de Douchy-les-Mines établi le 16 février 2024, notifié au préfet du Nord le 19 février 2024. Par un jugement du 23 avril 2024, le tribunal administratif de Lille a rejeté le déféré du préfet du Nord tendant à l’annulation de la désignation de Mme A… en qualité de conseillère municipale et à ce que soit prononcée l’élection de M. C… H…, trente-et-unième inscrit sur la liste. 2. D’une part, l’article L. 2121-4 du code général des collectivités territoriales prévoit que la démission d’un membre du conseil municipal  » est définitive dès sa réception par le maire, qui en informe immédiatement le représentant de l’Etat dans le département « . Aux termes du premier alinéa de l’article L. 270 du code électoral :  » Le candidat venant sur une liste immédiatement après le dernier élu est appelé à remplacer le conseiller municipal élu sur cette liste dont le siège devient vacant pour quelque cause que ce soit (…) « . La désignation faite en application de ces dispositions résulte de la proclamation du candidat, rendue publique par la mention de son nom dans le tableau du conseil municipal. 3. D’autre part, aux termes de l’avant-dernier alinéa de l’article L. 231 du code électoral :  » Les agents salariés communaux ne peuvent être élus au conseil municipal de la commune qui les emploie (…) « . 4. Il résulte de l’instruction que le maire de la commune de Douchy-les-Mines a été informé le 9 janvier 2024 de la démission de M. B…. La désignation de sa remplaçante, Mme A…, est intervenue le 16 février 2024, date d’établissement du tableau du conseil municipal comprenant son nom. Il résulte en outre de l’instruction que si Mme A… était, le 9 janvier 2024, salariée de la commune de Douchy-les-Mines, elle ne l’était plus à la date de la proclamation de sa désignation comme conseillère municipale, rendue publique par la mention de son nom dans le tableau du conseil municipal établi le 16 février 2024, à la suite de sa mutation à la communauté d’agglomération de la Porte du Hainaut à compter du 1er février 2024. Il s’ensuit que Mme A… n’était pas atteinte par l’inéligibilité édictée par les dispositions de l’article L. 231 du code électoral citées au point précédent. 5. Il résulte de ce qui précède que, sans qu’il soit besoin de se prononcer sur sa recevabilité, la requête de M. H… ne peut qu’être rejetée, de même, en tout état de cause, que les conclusions du préfet du Nord. 6. Les dispositions de l’article L. 761-1 du code de justice administrative font obstacle, d’une part, à ce que soit mise à la charge de Mme A…, qui n’est pas la partie perdante dans la présente instance, la somme que demande M. H… au titre de frais exposés et non compris dans les dépens et, d’autre part, à ce que la commune de Douchy-les-Mines, qui n’est présente qu’en tant qu’observateur et n’a pas la qualité de partie au litige, puisse obtenir une somme au même titre. En outre, il n’y a pas lieu, dans les circonstances de l’espèce, de faire droit aux conclusions présentées par Mme A… au titre des mêmes dispositions. D E C I D E : ————– Article 1er : La requête de M. H… et les conclusions du préfet du Nord sont rejetées. Article 2 : Les conclusions présentées par la commune de Douchy-les-Mines et par Mme A… au titre de l’article L. 761-1 du code de justice administrative sont rejetées. Article 3 : La présente décision sera notifiée à M. C… H…, à Mme G… A… et au ministre de l’intérieur. Copie en sera adressée à la commune de Douchy-les-Mines.

Bertrand Dacosta, Mme Anne Egerszegi, présidents de chambre ; M. Nicolas Polge, M. Vincent Daumas, M. Olivier Yeznikian, Mme Rozen Noguellou, conseillers d’Etat, M. Jérôme Goldenberg, conseiller d’Etat en service extraordinaire et M. Lionel Ferreira, maître des requêtes-rapporteur. Rendu le 29 novembre 2024. Le président : Signé : M.
