🪨 PipeDream on the Acorn Archimedes 🛠️

A truly unique combination. We have the first ARM-based home computer, powering a bespoke OS, running software that says, "The barriers between productivity apps are a lie we tell ourselves."

This introduced so many new technologies, I had to run a check on "Where are they now?" The ARM chip's legacy is a given, but the other stuff in the stack might surprise you.

@tml I always wonder, how much there is ship under the surface. And in what shape. #Archimedes

La cosa più interessante degli Acorn Archimedes: montano le prime CPU ARM, le stesse su cui oggi si basano i comuni smartphones e dispositivi come Raspberry pi.
E' davvero una bella macchina nell'insieme, seppure sia stata meno popolare e diffusa rispetto ai giganti Amiga e AtariST.

The most interesting thing: it uses an early ARM chip, the same platform that today powered your smartphone, Raspberry and many other low-power or portable device.

The Generative Excess: Soul, Dream, and Idea

There are three things you cannot show me. You cannot open your hand and reveal your soul. No technology exists to replay your dream from last night with any fidelity. And no surgeon can extract from your skull the moment a thought first assembled itself into an idea. Each of these phenomena exists, if it exists at all, only as a first-person event, invisible to external observation, resistant to measurement, and stubbornly private. That shared inaccessibility is worth taking seriously, because it suggests that the most important operations of human consciousness happen in a place that science can describe from the outside but never enter.

Start with what each one does. The soul, across most Western and Eastern philosophical traditions, answers the question of continuity. It explains why the person who fell asleep last night and the person who woke this morning are the same agent. Whether you locate it in the Aristotelian psyche as the animating form of a living body, or in the Cartesian res cogitans as a thinking substance separate from matter, or in the Hindu atman as an eternal self passing through incarnations, the soul functions as the ground of identity. A dream, by contrast, disrupts continuity. You enter a dream stripped of executive function, unable to recognize logical impossibilities, occupying spaces that shift without transition. You become a spectator inside your own mind, watching a performance you did not commission and cannot direct. A waking idea occupies a third position: it is an act of construction, a moment when the mind assembles discrete elements into a new configuration that did not previously exist. Souls persist. Dreams intrude. Ideas emerge.

That tripartite distinction exposes different relationships to volition. You do not choose to have a soul or to lack one; it is either a feature of your ontological situation or it is a fiction, and in neither case does your preference matter. You do not choose to dream, though the content of dreams appears to draw from waking experience in ways that suggest unconscious editorial selection. J. Allan Hobson’s activation-synthesis hypothesis, proposed in 1977, argued that dreams arise when the brainstem sends random electrical signals during REM sleep and the cortex, desperate to impose order on noise, weaves those signals into narrative. If Hobson was even partially correct, dreaming is the brain telling itself stories to explain its own involuntary electrical activity. A waking idea, however, carries at least the sensation of agency. When Archimedes stepped into his bath and recognized the principle of displacement, or when August Kekulé reported seeing the structure of benzene in a half-waking vision of a snake consuming its own tail, the idea arrived with the force of discovery, as though the thinker had earned it through effort.

Both of those famous examples blur the boundary between dreaming and waking thought. Kekulé’s breakthrough came in a hypnagogic state. Archimedes’ eureka arrived during the kind of relaxed, unfocused attention that resembles dream consciousness more than analytical reasoning. Henri Poincaré described the same experience in his 1908 essay on mathematical creativity: after days of failed conscious effort on Fuchsian functions, the solution arrived unbidden while he was boarding a bus, carrying with it an immediate certainty of correctness. The conscious labor had been necessary, but the synthesis itself happened somewhere else, in a cognitive region that shares more architecture with dreaming than with deliberate calculation. This pattern appears so often in the history of science and art that it demands explanation. The waking mind prepares the ground; the sleeping or distracted mind plants the seed; and the idea appears at the border between the two states, as if consciousness needed to look away before it could see.

All three phenomena involve pattern recognition operating below the threshold of awareness. The soul, if we follow the phenomenological line from Edmund Husserl forward, is the unified field of intentionality that makes pattern recognition possible in the first place. It is the subject that does the recognizing, the “I” that precedes every act of perception. Dreams are pattern recognition run wild, freed from sensory constraint and logical discipline, which is why dream content so often features the recombination of familiar elements into unfamiliar arrangements: your childhood kitchen with the ceiling of a cathedral, a conversation with a dead relative conducted in a language neither of you spoke. An idea, when it arrives, typically feels less like construction and more like recognition, as though the pattern was already present and the thinker merely noticed it. That feeling of discovery rather than invention has troubled epistemologists for centuries, because it implies that ideas have an existence independent of the minds that think them, a position that leads straight to Plato and the theory of Forms, where all knowledge is recollection of truths the soul apprehended before birth.

The differences become sharpest when you examine communicability and persistence. An idea, once formed, can be externalized. You can write it down, speak it, encode it in mathematics or music or architecture, and another person can receive it with reasonable fidelity. Euclid’s geometric proofs remain operative twenty-three centuries later. Darwin’s natural selection survived its author by more than a hundred years and shows no sign of weakening. The idea is the one member of this trio that outlives its host. A dream, however, resists translation. Anyone who has tried to recount a dream knows the experience of watching its internal logic evaporate in the telling. The narrative that felt saturated with meaning at 3 a.m. becomes, by breakfast, a string of non-sequiturs that embarrass the teller. Dreams are experiences that degrade upon export; their meaning, if they have meaning, may be inseparable from the neurochemical state that produced them. The soul occupies the most isolated position of all. You can describe your beliefs about the soul, argue for its existence or its absence, construct elaborate theological frameworks around it, but you cannot transmit the thing itself. If the soul is real, it is the most private object in existence, the one possession that cannot be shared, stolen, or photographed.

I want to take a position on truth-value here rather than retreat into academic equivocation. A waking idea can be tested. It can be wrong, and its wrongness can be demonstrated. Kekulé’s benzene ring was either an accurate model of molecular structure or it was a fantasy, and subsequent X-ray crystallography confirmed the model. Ideas submit to verification, and that submission is what gives them their power and their danger. Dreams make no truth claims and therefore cannot be falsified; they operate in a space where contradiction is a feature rather than a defect, where you can be simultaneously yourself and someone else, where gravity applies in one room and not the next. The soul occupies the most precarious epistemic position of the three, because it asserts an enormous truth claim (that personal identity has a metaphysical ground, that you are more than your biology) while offering no mechanism for verification. This is why the soul has migrated over the past four centuries from philosophy into theology: it requires faith in a way that ideas and dreams do not.

Yet there is a way to read all three as expressions of a single underlying capacity. Call it generative excess. A soul posits a self that is more than the sum of its biological processes. Dreams generate entire worlds from stored fragments without any current sensory data. An idea produces a new structure from existing elements that, in their previous arrangement, did not suggest that structure. In each case, something appears that was not contained in its antecedents. The mind, whether sleeping or waking, whether reflecting on its own nature or assembling a new theorem, keeps producing more than its inputs would predict. Whether you call that capacity consciousness, emergence, or grace depends on your commitments, but the surplus is common to all three phenomena. Differences among the three lie in duration, controllability, and communicability. Souls endure, or claim to. Ideas can be transmitted. Dreams do neither, and perhaps that is why, of the three, dreaming remains the most mysterious and the least respected, despite being the one phenomenon whose existence no one disputes.

What holds these three together is the stubborn fact that the human mind refuses to be merely reactive. It insists on generating experience that exceeds what the world hands it. That insistence may be our defining characteristic as a species, and it may also be our greatest vulnerability, because a mind that generates more than it receives is a mind that can deceive itself with its own productions. The soul may be one such self-deception. The dream is a nightly demonstration of how persuasive such deceptions can be. And the idea, when it is wrong, can lead entire civilizations into error. The generative excess gives us Euclid’s geometry and astrology, penicillin and phrenology, cathedral architecture and conspiracy theories. The capacity itself is neutral; what matters is whether we can distinguish its products from its illusions. That question has occupied philosophy since Socrates, and we are no closer to settling it now than we were in Athens. The soul, the dream, and the idea all emerge from the same restless source, and the fact that we cannot see that source directly may be the most important thing about it.

Just posted a new devlog for our C-based web engine, Archimedes!

It's been a long road from Pygame to a custom C/Emscripten stack. I'm breaking down the architectural hurdles of moving away from our Daedalus library and how my collaborator @smattymatty has been stress-testing the engine with a vampire survivors clone and recent game jams.

To celebrate the progress, I've rewritten my old ( and very broken ) Game of Life simulator from the ground up. It's a great feeling to see a legacy project running smoother than ever on new, custom-built foundations.

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.’

@paysmaths @Theoremoftheday I think it is worth noting that there are two different definitions of semi-regular/archimedean solids.

- Requiring the same configuration at each vertex gives you 14 solids.

- Requiring that there is a symmetry carrying any vertex to any other gives you 13.

The rhombicuboctahedron and the pseudo-rhombicuboctahedron (see attached images) have the same vertex configurations, but only the first one satisfies the symmetry condition.

Archimedes found 13 solids, according to Pappus' ‘Collection’ (our only source for his work on this).

For details of the long-standing confusion of the two definitions and the resulting classes, see B. Grünbaum. ‘An enduring error’. In: Elemente der Mathematik. 64, no.3 (2009), pp.89–101. DOI: 10.4171/EM/120

"Do not disturb my circles." — Archimedes. 📐✨ ⭕
#Archimedes #AncientGreek #DoNotDisturb #MathArt #HistoryVibes #JohnRoss7 #Mastodon

Book XVI of Girolamo Cardano's (1501–76) ‘De Subtilitate’, a compendium of natural philosophy, begins by presenting sixty useful properties of geometrical figures, and says:

‘These are the sixty properties, outstanding in distinction and beauty and regard [nobilitate, & pulchritudine, & admiratione præstantiores], of the geometrical figures both surface and solid. Yet it does not escape me that properties exist that are practically numberless, but cannot be compared with these for elegance’

Some of the properties Cardano so admired seem to lapse into triviality, but others are important results from Euclid, Archimedes, Apollonius, and Ptolemy. For example:

Let $A_i$ be the point at the end of the $i$-th turn of an archimedean spiral. Consider the line through the $A_i$ and the perpendicular to this line through the origin $O$. Suppose that the tangent to the spiral at $A_i$ intersects the perpendicular at $B_i$ . Then $OB_i$ equals the circumference of the circle with centre $O$ and radius $OA_i$ (see attached image).

This result effectively comprises Propositions 18+19 of Archimedes' ‘On Spirals’.

#MathematicalBeauty #elegance #Cardano #Archimedes #spiral

The thirteen archimedean solids are the polyhedra (other than the five regular solids) all the faces of which are regular polygons and where for each pair of vertices some symmetry transformation carries one vertex to the other (see 1st attached image).

According to Pappus (fl. c.300–c.350 CE), who wrote a half-millennium later, Archimedes discovered them. The context of Pappus' report suggests that Archimedes was seeking polyhedra inscribable in spheres.

Archimedes excluded the infinite classes of prisms and anti-prisms, in which two n-gons are joined by squares or equilateral triangles (2nd attached image). Although they satisfy the definition, and are technically inscribable in spheres, they are somehow not ‘sphere-like’.

This suggests that Archimedes may have been influenced by the aesthetic preference for circles and spheres that descended from Pythagoras.

#ArchimedeanSolids #RegularSolids #polyhedra #Archimedes #Pappus #HistMath

Leonardo Pisano (c.1170–after 1240), dubbed ‘Fibonacci’, thought that Archimedes' proof that π was between $3\frac{10}{71}$ and $3\frac{1}{7}$ was beautiful [pulcra].

Archimedes' proof proceeds by calculating approximate ratios of the perimeters of 96-gons circumscribed about and inscribed in a circle to the diameter of that circle, implicitly starting with dodecagons and repeatedly bisecting edges to obtain 24-, 48-, and then 96-gons (see attached image).

Fibonacci’s judgement seems to be the earliest extant description of a *proof* as beautiful in the European tradition. [Al-Nasawī (fl. 1029–44) had earlier described a proof as beautiful.]

But there is a twist in the story...

1/3

#MathematicalBeauty #BeautifulProof #HistMath #Fibonacci #Archimedes #Pi

As noted in a previous post, Archimedes thought highly of the result that the ratio of either the volumes or surface areas of a cone, a sphere, and a cylinder exactly circumscribing them is $1:2:3$.

So did others: three centuries later, the architect Nicon (d.149/50 CE), father of the philosopher and physician Galen (129–c.210/217 CE), thought it fitting to point out the ratio of the configuration in a public inscription in his city, Pergamon:

‘the cone, the sphere, the cylinder.
If a cylinder encloses the other two shapes,
[...]
Competition the principle and in solids
the progression $1 ∶ 2 ∶ 3$,
a noble, divine equalization,
but also mutual interdependence
of the solids, always in the ratio $1 ∶ 2 ∶ 3$.
They should be beautiful and wonderful,
the three solid shapes’

Nicon doubtless admired these ratios as an architect: a sphere inside a cylinder brings to mind the Pantheon at Rome, of which the Temple of Zeus Asclepius Soter in Pergamon was a half-scale copy. These buildings were designed so that a basically cylindrical rotunda was crowned with a hemispherical dome under which a sphere would fit (see attached image).

#MathematicalBeauty #HistMath #Archimedes #geometry #architecture #aesthetics

Max Dehn (1878–1952) said that Archimedes’ (c.287–212 BCE) discovery that the surface area of a sphere was four times its great circle was the one of the most beautiful results of Greek mathematics.

Archimedes himself had a high opinion of this result and two others in his two books ‘On the Sphere and the Cylinder’: that the volume and surface area of a sphere and a cylinder exactly circumscribing it are in the ratio $2 : 3$. One can add a cone fitting inside the cylinder to have ratios $1 : 2 : 3$ (see 1st attached image).

It has been suggested that Archimedes’ conjectures for these ratios may have been guided by a conscious or unconscious search for beautiful integer ratios between geometric configurations. There is no direct evidence for this motivation, but Archimedes’ work seems to exhibit a preference for small integer ratios.

According to Plutarch, Archimedes desired that his tomb should be marked by a cylinder enclosing a sphere and an inscription of the ratio of the one to the other; Cicero related how he had sought out Archimedes’ tomb and found a column just so inscribed (see 2nd attached image).

Archimedes – A Python toolkit for hardware engineering

I'm trying to get the Acorn Archimedes core for the Mister working.

I'm able to boot it with the Ridcos 3 rom, and the desktop starts. However, I have so far failed to add a hard disc image to it. I created an empty file, and used 'configure idefsdiscs 1' as instructed in the readme for the core. I've had varying degrees of success with this (seeminly depending on the size of the image), but even when a disc is detected, it tells me it's not formatted.

I apparently need a tool called HDform, which I downloaded a floppy image and ran. However, it gives me an error saying it doesn't recognise the disc.

One tried all sorts of variations, and nothing works. Is there anyone with Archimedes experience that can provide some tips?

#retrocomputing #mister #acorn #archimedes

Today afternoon we'll try to repair an #Archimedes #PC600, which was donated to the museum a few weeks ago. Maybe it is something easy like resetting video mode, maybe something more complicated like defective parts. Fingers crossed for the first alternative.

There’s an exhibition of retro / classic home computing machines this week (Aug 21-28 2025) at Kingston University, so I had to drop in.

It was fun to see some old favourites again, and it was nice to see some youngsters engaging with the games I used to play. Turrican, Hunchback, Mario, Puzzle Bobble, Lemmings!

The Townhouse building at Kingston University has been open for several years already and I drive, walk or bus past it regularly, but never had a reason to pop in until now! It has the university library on the upper floors, and a cafe and event space on the ground floor. For the duration of this week, the Archive of Retro Computing has taken over the event space with this display.

It is nicely put together, with some machines set aside for coding, some for gaming; information about each system displayed alongside; some meta-history on topics like the British computing scene (Acorn vs Sinclair), Commodore and Amstrad, and the US elements. The back section is dedicated to vintage home gaming systems, from the 1977 Binatone Pong game, through Atari / Nintendo / Sega, up to the Super Nintendo and Jaguar.

There are also some super “deep cuts” in the collection, including the Tatung Einstein, which I don’t remember ever seeing or hearing about before…

From my personal history, the Binatone Pong game on display is I think slightly older than the simple dial paddle controllers than we had hooked up to the TV at home when I was young. No sign of the metal-clad Commodore PET that I remember tinkering with at primary school, but a range of other Commodore machines are on show, including the classic Commodore 64 (I have one of these, from a former Twitter coworker!), and several other models I’m less familar with.

My first home computer, the Acorn Electron, is right there, running Arcadians, a Space Invaders clone I must have spent hours on back in the day. My own Electron ended as a hand-modded machine featuring switchable headphone or regular speaker output. I’m still quite proud of that relatively low-tech little hardware hack from back then.

Next along in my own line would have been the Amstrad CPC (with 3″ disk drive) that my uncle had, and pointed me towards on most visits to his house. I have memories of Jet Set Willy and Manic Miner on that one. The little info card here tells the story of how Alan Sugar did a deal on the disk drives such that Hitachi ended up having to keep making them, at a loss, even though the 3″ disk format was otherwise dead in the water.

My school had a very well-equipped computer room with (I think) about 30 BBC Master and Micro computers, so I was very much an Acorn boy and learned BBC BASIC as my first proper coding language (along with a tiny bit of 6502 assembler). Later on, the school computer room was upgraded with several Acorn Archimedes. My brother had an A3000 in his bedroom… I had an Acorn Risc PC with a StrongARM processor, way faster than the x86 PCs available at the time! The BBC Master and A3000 are present and correct in the exhibition (there’s a BBC Micro as well, alongside the Electron).

We also had a Super Nintendo, which is one of the last of the home gaming consoles in the exhibition (I overheard someone say that the Playstation, our next games console as a family, was where gaming all went wrong and 3D and got boring… I can sometimes understand that point of view!).

As an aside, I had a quick go on Wolfenstein 3D on the Jaguar in the corner there, and the controller for the Jaguar was bonkers! Chunky and not very friendly to use. The graphics seemed decent, with some kind of interpolation at distance? I don’t remember ever actually playing on a Jaguar when they were current…

Pretty much all of the machines had some kind of modification, both to output graphics to the LCD monitors in use, and/or to replace disk drives with some form of USB-floppy emulation, often with a Pi or something else doing the interfacing.

A fun trip down memory lane!

I found a school journal from 1993, when I was ten years old.

In it, were the following screenshots for operating a BBC Micro computer and/or an Archimedes computer.

In 1993, computer literacy was still coming into its own; software packages like spreadsheets and word processors hadn't gone mainstream -- certainly not in terms of ICT (Information Computer Technology) at pre-GCSE level.

But we did spend a lot of time in school learning about #Pendown, which was a very capable word processor:

I don't recall using Revelation to do anything, but it existed:

According to the forms in my journal, I didn't get very far.

Says it all, really... I was only ten.

I recently hacked #Elite on the #Acorn #Archimedes to send scores to a live scoreboard across an #Econet network.

I've just published a short article that explains how I did this.

I've just released !EliteNet, my first #RISCOS application in 30 years.

It allows #Archimedes #Elite to transmit to an #Econet multiplayer scoreboard (see Yoda’s score in the second screenshot, for example).

The story of #Archimedes’ “#Eureka!” moment is a famous anecdote about the ancient #Greek mathematician’s discovery of the #FirstPrinciples of #buoyancy.

Pondering how to determine if King Hiero II’s crown was made of gold, Archimedes noticed that water displaced in his bathtub was proportional to the volume of his submerged body.

This insight allowed him to measure the crown’s volume by submerging it in water and comparing the displaced water with that of pure #gold.
