Friedrich Schiller's (1759–1805) poem ‘Archimedes and the Student’ (see 1st attached image for typeset text):

To Archimedes came an inquisitive youth
“Initiate me,” he said to him, “into the divine science,
That bore such splendid fruit for the nation
And shielded the walls of the city from the sambuca!”
“Divine you call the science? It is,” replied the sage,
“But it was so, my son, even before it served the state.
If you want only fruit from her, even mortals can provide it;
Who courts the goddess, seeks not in her the woman.”

(The sambuca was a ship-mounted siege engine; see 2nd attached image. During the Roman siege of Syracuse, it failed in the face of the war-machines designed by Archimedes.)

In 1808, Carl Friedrich Gauss (1777–1855) became director of the observatory at Göttingen and in his inaugural lecture declared that mathematics in general and astronomy in particular had a value — at least in part aesthetic — that was prior to and independent of any utility:

‘The happy great minds who created and expanded astronomy as well as the other beautiful parts of mathematics were certainly not inspired by the prospect of future use: they searched the truth for its own sake and found in the very success of their efforts their reward and their happiness. I cannot avoid at this point reminding you of ARCHIMEDES […]. You must all know the beautiful poem by SCHILLER.’

Typeset text of Friedrich Schiller's poem ‘Archimedes and the Student’:

To Archimedes came an inquisitive youth
	‘Initiate me,’ he said to him, ‘into the divine science,
That bore such splendid fruit for the nation
	And shielded the walls of the city from the sambuca!’
‘Divine you call the science? It is,’ replied the sage,
	‘But it was so, my son, even before it served the state.
If you want only fruit from her, even mortals can provide it;
	Who courts the goddess, seeks not in her the woman.’Early modern depiction of a sambuca. Several ships are shown near a harbour wall. From two of the ships, sloping stepped platforms supported by ropes from the masts allow attacking soldiers to climb to the top of the walls. A caption below reads ‘Sambucæ Polybij, quarum alia et meuior forma in Herone’.

Since @lindasgoluppiart is mired in the world of political fords and #socks:

Today:

Take a tangerine, orange, satsuma, or some such, and try to unpeel it entirely in one long helical strip. How narrow can you make the strip and still only take 1 minute to unpeel the whole thing?

If you are doing this in #Dunelm, the area with all of the pillowcases is probably the quietest. Respect the staff and take the peel with you, though.

A ball is 3D. A sphere is the surface of a ball and is only 2D. It has just 2 coördinates for every point, latitude and longitude (i.e. θ and φ without r).

I know that @standupmaths has definitely covered this particular one. I've seen Matt do it. This is Key Stage 3 National Curriculum #maths as taught in secondary school.

As I said, you've got a loudness of teeth grinding metric for how many mathematicians are in your readership who can further take that beyond KS3 to the 2 centuries of maths built from Karl Freidrich #Gauss and others that are some of the underpinnings of 20th century relativistic #physics.

I don't know whether you have a metric for the number of physicists in your readership. Physicists's teeth tend to start out frictionless, perfectly cuboid, inertial, and in vacuo. (-:

Vím že už jedna z archívu dnes byla, ale dnes je to na den přesně patnáct let, co vznikla na kuchyňské lince tato "matematická fotografie" ze tří listů kancelářského papíru zatížených dvěma sklenicemi a celé to nasvítila stolní lampa. Kdybych měl vybrat mezi svými fotografiemi tři nejoblíbenější, tak tato bude mezi nimi.

[…Continued]

There are loads of resources on the WWW that do this far better justice, with more detail and less handwaving that I'm using here. There are also scads of pop science explanations by actual maths teachers. #Numberphile has #HannahFry discussing this with orange peel, for example. @standupmaths has probably covered it somewhere.

You'll know that you've reached the good stuff, the stuff that mathematicians and theoretical physicists deal in (knowing about intrinsic measure of curvature being necessary for a proper understanding of curved spacetime in General Relativity), when you come across the explanations that blithely throw in Christoffel symbols and Ricci tensors as if you know what the Hell they are on about.

Bear in mind that I am not the mathematics teacher in my family. But I do know what makes mathematicians's teeth grind. (-:

The #maths involves Karl Freidrich #Gauss's Theorem Egregium that was published in 1827. The 3D-ness, the embedding (of what is actually still only a 2D manifold) within a higher dimensional space, does not matter, and isn't the reason that flat maps of the surface of Terra don't work.

The reason is that a plane has (constant) Gaussian #curvature zero and a sphere has positive Gaussian curvature. It's impossible to have an isometry between two spaces with different Gaussian curvatures. Something always has to give.

A torus is a 2D surface embedded in 3D space, like a sphere. But there are parts of a torus with zero Gaussian curvature, and those parts *can* be projected onto a plane without distortion. Likewise, a cone and a cylinder have constant zero Gaussian curvature and can also be projected onto a plane.

Lors du dernier congrès annuel de l'association Math-Ador à Laval (53), en novembre 2025, les travaux en réunions plénières ont été précédés, comme à l'accoutumée, de deux jours de rencontres bilatérales…
Chacun des 53 présents a ainsi rencontré en tête à tête chacun des 52 autres. Chacune de ces rencontres concernant 2 personnes, il y en a eu (53×52)/2.
Une autre façon d'envisager cette question est : numérotons de 1 à 53 les participants ; le premier a rencontré les 52 autres ; le second en a rencontré 51 non compris le premier déjà comptabilisé ; le troisième 50 non compris les numéros 1 et 2 etc… et ce décompte s'achève avec la rencontre entre les numéros 52 et 53. Il y a donc 52+51+50+...+1 rencontres bilatérales.
Ainsi, 52+51+50+...+1 = (53×52)/2.

NB : on prévoit non plus 53 participants, mais n+1 pour le congrès 2026, d'où la formule de Gauss :
n+(n-1)+(n-2)+...+1 = (n+1).n/2

Bonne semaine, OldGH

Mastodon messaging is nice to learn #DistributedSystems and #Concurrency. If I start counting with "0" and my followers try to increase by 1 in each message we will get a nice tree. I wonder if it is #Gauss shaped?

Samsung rezygnuje z rozwijania własnego modelu AI o nazwie Gauss

Południowokoreański potentat nie będzie dalej rozwijał własnego, izolowanego środowiska AI o nazwie Gauss, firma zmienia koncepcję rozwoju sztucznej inteligencji, wybiera współpracę zamiast izolowanego, autorskiego rozwiązania.

O sprawie jako pierwsze (najprawdpodobniej) poinformowało południowokoreańskie źródło, serwis Finance Scope. Autorzy informacji sugerują, że wydarzeniem, które zmieniło nastawianie prezesa Lee Jae-Yonga do kwestii rozwoju autorskiej platformy sztucznej inteligencji było zrealizowane w lipcu ubiegłego roku spotkanie z CEO OpenAI, Samem Altmanem.

W rezultacie Samsung zmienił podejście w kwestii wewnętrznego wykorzystywania we własnych systemach produkcji, projektowania, badań i rozwoju, systemów sztucznej inteligencji. Jak informuje południowokoreański serwis, kierownictwo Samsung Electronics wydało polecenie, aby najpierw wdrożyć w dziale półprzewodników zewnętrzną sztuczną inteligencję.

Wdrażanie zewnętrznych algorytmów AI w firmie Samsung ma stopniowo być rozszerzane również na inne działy koreańskiego giganta. Celem jest wykorzystanie AI do lepszego monitorowania procesów w czasie rzeczywistym, przewidywania ewentualnych defektów i zwiększania wydajności.

OpenAI prezentuje usługę Operator – Agent AI w przeglądarce zrobi za ciebie wszystko

Samsung liczy, że zastosowanie odpowiednio wytrenowanych algorytmów sztucznej inteligencji w wewnętrznych procesach badawczych i produkcyjnych pozwoli efektywnie analizować dane z czujników, co przełoży się na zmniejszenie wskaźników awaryjności i redukcję czasów przestojów produkcyjnych, a także wyższą jakość konserwacji predykcyjnej, co pozwoli skuteczniej zapobiegać ewentualnym awariom.

Samsung liczy też, że AI spięta z procesami produkcyjnymi pozwoli lepiej reagować na zmienność globalnego łańcucha dostaw, pozwoli dokładniej prognozować popyt i zarządzać zapasami.

Projekt Gauss, który pierwotnie miał być właśnie skupioną na bezpieczeństwie, wewnętrzną platformą sztucznej inteligencji, został na razie odsunięty na dalszy plan. Samsung oficjalnie nie zamknął lecz jedynie wstrzymał ów projekt, niemniej przy rosnącym tempie rozwoju modeli AI w skali globalnej, raczej wątpliwe by firma powróciła do własnego rozwiązania, które bez dalszego rozwoju stanie się szybko przestarzałym i niepotrzebnym już rozwiązaniem.
