“Scuse me while I kiss the sky”*…

In 1967, Jimi Hendrix’s manager, Chas Chandler arranged for Jimi to meet Cream…

There was a particular night when Cream allowed Jimi to join them for a jam at the Regent Street Polytechnic in central London. Meeting Clapton had been among the enticements Chandler had used to lure Hendrix to Britain: “Hendrix blew into a version of [Howlin’ Wolf’s] ‘Killing Floor’,” recalls [Tony] Garland, “and plays it at breakneck tempo, just like that – it stopped you in your tracks.” [Keith] Altham recalls Chandler going backstage after Clapton left in the middle of the song “which he had yet to master himself”; Clapton was furiously puffing on a cigarette and telling Chas: “You never told me he was that fucking good.” – source

Hendrix’s extraodinary virtuosity has, altogether justly, gotten a great deal of attention; less well noted, his incredible mastery of the technology of music making, recording, and performance. Rohan Puranik explains…

3 February 1967 is a day that belongs in the annals of music history. It’s the day that Jimi Hendrix entered London’s Olympic Studios to record a song using a new component. The song was “Purple Haze,” and the component was the Octavia guitar pedal, created for Hendrix by sound engineer Roger Mayer. The pedal was a key element of a complex chain of analog elements responsible for the final sound, including the acoustics of the studio room itself. When they sent the tapes for remastering in the United States, the sounds on it were so novel that they included an accompanying note explaining that the distortion at the end was not malfunction but intention. A few months later, Hendrix would deliver his legendary electric guitar performance at the Monterey International Pop Festival.

“Purple Haze” firmly established that an electric guitar can be used not just as a stringed instrument with built-in pickups for convenient sound amplification, but also as a full-blown wave synthesizer whose output can be manipulated at will. Modern guitarists can reproduce Hendrix’s chain using separate plug-ins in digital audio workstation software, but the magic often disappears when everything is buffered and quantized. I wanted to find out if a more systematic approach could do a better job and provide insights into how Hendrix created his groundbreaking sound.

My fascination with Hendrix’s Olympic Studios’ performance arose because there is a “Hendrix was an alien” narrative surrounding his musical innovation—that his music appeared more or less out of nowhere. I wanted to replace that narrative with an engineering-driven account that’s inspectable and reproducible—plots, models, and a signal chain from the guitar through the pedals that you can probe stage by stage…

[And probe it Puranik does– fascinatingly, stage by stage…]

… Hendrix didn’t speak in decibels and ohm values, but he collaborated with engineers who did—Mayer and Kramer—and iterated fast as a systems engineer. Reframing Hendrix as an engineer doesn’t diminish the art. It explains how one person, in under four years as a bandleader, could pull the electric guitar toward its full potential by systematically augmenting the instrument’s shortcomings for maximum expression.

As we plug in, we might send well-connected birthday greetings to another wizard with wires, Geoff Tootill; he was born on this date in 1922. An electronic engineer and computer scientist, he worked (with Freddie Williams and Tom Kilburn) to design a computer memory. To that end they built the first electronic stored-program computerthe Manchester Baby— at the University of Manchester in 1948.

The Baby was not intended to be a practical computing engine, but was instead designed as a testbed for the Williams tube, the first truly random-access memory. Nonethless, Baby worked: Alan Turing moved to Manchester to use it, and the following year, it inspired the Ferranti Mark 1, the world’s first commercially available electronic general-purpose stored-program digital computer.

“It’s peculiar. It’s special. There’s very little of it, but it has this pivotal role in the universe.”*…

One of the oldest, scarcest elements in the universe has given us treatments for mental illness, ovenproof casserole dishes, and electric cars. Increasingly, our response to climate change seems to depend on it. But how much do we really know about lithium? Jacob Baynham explains…

The universe was born small, unimaginably dense and furiously hot. At first, it was all energy contained in a volume of space that exploded in size by a factor of 100 septillion in a fraction of a second. Imagine it as a single cell ballooning to the size of the Milky Way almost instantaneously. Elementary particles like quarks, photons and electrons were smashing into each other with such violence that no other matter could exist. The primordial cosmos was a white-hot smoothie in a blender.

One second after the Big Bang, the expanding universe was 10 billion degrees Kelvin. Quarks and gluons had congealed to make the first protons and neutrons, which collided over the course of a few minutes and stuck in different configurations, forming the nuclei of the first three elements: two gases and one light metal. For the next 100 million years or so, these would be the only elements in the vast, unblemished fabric of space before the first stars ignited like furnaces in the dark to forge all other matter.

Almost 14 billion years later, on the third rocky planet orbiting a young star in a distal arm of a spiral galaxy, intelligent lifeforms would give names to those first three elements. The two gases: hydrogen and helium. The metal: lithium.

This is the story of that metal, a powerful, promising and somehow still mysterious element on which those intelligent lifeforms — still alone in the universe, as far as they know — have pinned their hopes for survival on a planet warmed by their excesses…

[Baynham tells the story of this remarkable element, the development of it many uses (in psychopharmacology, in materials science, and of course in electronics– especially batteries), the rigors of extracting it for those purposes, and the challenges that its scarcity– and its potency– present…]

… Long before cell phones and climate anxiety and the Tesla Model Y, long before dinosaurs and the first creatures that climbed out of the ocean to walk on land, long before the Earth formed from swirling masses of cosmic matter heavy enough to coalesce, back, way back, to the infant universe, to the dawn of matter itself, there were just three types of atoms — three elements in the blank canvas of space. One of them was lithium. It was light, fragile and extremely reactive, its one outer electron tenuously held in place.

Everything we have done with lithium, all its wondrous applications in energy, industry and psychiatry, somehow hinges on this basic structure, a sort of magic around which we’re increasingly engineering our future. Lightness is usually associated with abundance on the periodic table — almost 99% of the mass of the universe is just the lightest two elements. Lithium, however, is the third lightest element and still mysteriously scarce…

As we muse on materials, we might send densely-packed birthday greetings to Philip W. Anderson; he was born on this date in 1923. A theoretical physicist, he  shared (with John H. Van Vleck and Sir Nevill F. Mott) the 1977 Nobel Prize for Physics for his research on semiconductors, superconductivity, and magnetism. Anderson made contributions to the theories of localizationantiferromagnetismsymmetry breaking including a paper in 1962 discussing symmetry breaking in particle physics, leading to the development of the Standard Model around 10 years later), and high-temperature superconductivity, and to the philosophy of science through his writings on emergent phenomena. He was a pioneer in the field that he named: condensed matter physics, which has found applications in semiconductor and laserr technology, magnetic storage, liquid crystals, optical fibers, nanotechnology, quantum computing, and biomedicine.

“For every complex problem, there’s a solution that is simple, neat, and wrong”*…

Last year, in explaining the Biden Administration’s emerging new economic policy, National Security Advisor Jake Sullivan talked of a “small yard, high fence” approach to its trade with China. The idea: to place strict restrictions on a small number of technologies with significant military potential while maintaining normal economic exchange in other areas.

The estimable Henry Farrell argues that this approach to technology and China is working poorly (though, he suggests, it will work much worse if Trump wins and takes office in January). Self-reinforcing political feedback loops and self-reinforcing expectations are leading to breakdown.

The fundamental problem of managing geopolitics through manipulating technological trajectories is not readily solvable given existing means, Farrell suggests. We live in a much more complex world than existing state institutions are capable of handling. Therefore, he argues, we need to remake the state…

… Making the right choices in a complex policy environment requires an approach that is a world away from the application of brute force at scale. Your maps of the environment are going to be all wrong when you go in, and brute force is likely to have unexpected consequences. It isn’t just that you are going to make mistakes (you are), but your map of the actual problem you are trying to solve is likely to be utterly out of whack. As you try to catch up with China on EV, you discover that you don’t understand the market right. As you try to impose controls on military use of semiconductors, you find out that you don’t have the information you need to really actually understand how the semiconductor market works.

The problem – as Jen Pahlka’s book Recoding America explains at length – is that addressing such complex problems does not fit well with the way that the U.S. government works. When you are trying to impose order a vast sprawling bureaucracy, which is its own mid-sized global economy, and when your people don’t trust government much, you rely on rigid contracting systems, which define the problem in advance down to its finest details, even if that definition is out of whack with reality. You don’t build connections between the bureaucracy and outside actors, unless they run through cumbersome and rigidly pre-defined channels because it takes months or years to get approval for such connections. And you certainly don’t try to remake policy in realtime as your understanding of the situation changes. Pahlka’s book is cunningly disguised as an account of US software outsourcing practices. If it mentions either ‘national security’ or ‘economic security’ once, I don’t remember it. But it is arguably (along with Dan Davies’ similarly motivated The Unaccountability Machine) the most important book on these topics of the last twenty years. [Your correspondent heartily agrees.]…

… what do you do – is this. You start to think… about how to build economic security institutions that are designed from the ground up to manage complexity. If you want to take ‘small yard, high fence’ seriously as a policy approach, you need to build the apparatus to discover what lies inside, what lies outside, and what the barriers ought be. That apparatus – and its prescriptions – need to change over time both to match a better understanding of the policy environment, and changes in the environment itself.

And we don’t have the apparatus to actually implement small yard, high fence properly. Nor do we have it for pretty well every other plausible economic security policy you might imagine, short of a brute force decoupling of the U.S. and Chinese economies. And if you did that, you would need enormous capacity to manage the horrifically complex aftermath, if that aftermath could even be managed at all.

Clearly, it is far easier to make these arguments in the general than the particular. Saying that you need reforms is straightforward, but figuring out what they ought to be, let alone how to implement them in current political circumstances, is an altogether more difficult challenge. But it is where the debate needs to be going – and there is a role for technology in it. We are in a situation that rhymes in weird ways with the situation discovered by Vannevar Bush after World War II – recognizing that the needs of government had changed, that vastly better information and feedback systems were required to meet those needs, and that even if we didn’t exactly know what those systems were, we needed to start figuring them out, and quickly. That world had its pathologies. This one does too. But to prevent them becoming worse, we need better ways to manage them, and to ensure that the solutions are better than the problems that they are supposed to mitigate.

This is – obviously – a radical set of claims. But it’s one that is entailed by the diagnosis of the problem that I’ve presented. If we need to manage complex challenges – of which the U.S. China relationship is only one – we need a state that is capable of managing complexities. We don’t have one. And that remains a first order problem, regardless of however hawkish or dovish you are…

We need a new kind of state for the new geopolitics: “‘Small Yard, High Fence’: these four words conceal a mess,” from @himself.bsky.social (and @pahlkadot.bsky.social). Eminently worth reading in full.

As we ruminate on restructuring, we might recall that it was on this date in 1954 (7 years after the transistor was developed at Bell Labs) that Texas Instruments introduced the Regency TR-1, the first commercially-manufactured transistor radio. Its performance was mediocre, but its small size and portability drove sales of over 150,000 units.

Further to Farrell’s and Pahlka’s points, it’s instructive to ponder what became of the transistor radio as a product category (and of the competitors in it) over the next few decades– and the altogether-unanticipated plethora of small, convenient, hand-held product categories it spawned: calculators, mobile phones, tablets… and whatever comes next…

“Engineering is the art of modeling materials we do not wholly understand, into shapes we cannot precisely analyze, so as to withstand forces we cannot properly assess, in such a way that the public has no reason to suspect”*…

… and so, for a very long time, it has been. Consider the case of the inventive Ismail al-Jazarī, a predecessor of Da Vinci…

… Al-Jazarī, who passed away in 1206, served as the chief engineer for the court of the Artuqids in Diyarbakir. His Book of Knowledge of Ingenious Mechanical Devices lives up to its name, detailing lock-like devices for raising water, sophisticated zodiac clocks, avian automata able to produce song, and a showering system for King Salih, who “disliked a servant or slave girl pouring water onto his hands for him”. He invented bloodletting technologies, mischievous fountains, segmental gears, and a chest (sundūq) that featured a security system with four combination dials — presumably a safe for storing valued possessions — and has been subsequently dubbed “the father of robotics”, due to his creation of a life-like butler who could offer guests a hand towel after their ablutions. Al-Jazarī’s contemporaries already recognized his eminence as an engineer, referring to him as unique and unrivaled, learned and worthy. He stood on the shoulders of Persian, Greek, Indian, and Chinese precursors, while Renaissance inventors, in turn, stood on his.

The Book of Knowledge of Ingenious Mechanical Devices contains some fifty mechanical devices divided into six categories: clocks; vessels and figures for drinking sessions; pitchers, basins, and other washing devices; fountains and perpetual flutes; machines for raising water; and a miscellaneous category, where we find a self-closing door. The second category is perhaps the most intriguing, and grants some insight into the extravagant concerns of al-Jazarī’s courtly patrons. One machine — “a standing slave holding a fish and a goblet from which he serves wine to the king” — is programmed to dispense clarified wine every eighth of an hour for a certain period. Numerous similar devices follow: robots that drink from goblets, which are filled from the recycled contents of their stomachs; automaton shaykhs that serve each other wine that each consumes in turn; a boat full of mechanical slave girls that play instruments during drinking parties. Not unlike our “AI assistants”, al-Jazarī’s inventions are never allowed to transcend the category of indentured laborer, reproducing the inequalities of social relations across the human-machine divide.

The illustrations from the Berlin manuscript are notably different than some of its sister specimens, such as the ornate pair of manuscripts held in Leiden. Here the images are mainly in-line illustrations and seem more focused on technical details and inner workings than other versions, which tend to lean toward aesthetic exteriors. Red and yellow predominate, offset by the occasional body of water in indigo blue. Gears and levers are rich in tone, while humanoid figures get left as simple, colorless sketches. To the contemporary viewer, the illustrations invert the power dynamic that is so present in al-Jazarī’s text. Machines come to the foreground; humans are incidental figures, almost irrelevant…

Putting material to work. More– and many more illustrations: “Ismail al-Jazarī’s Ingenious Mechanical Devices,” from @PublicDomainRev.

As we imagine machines, we might spare a thought for Henry Christopher Mance; he died on this date in 1926. An electrical engineer and inventor, he was instrumental in laying the earliest underwater telecom cables (under the Persian Gulf) and developed the Mance method of detecting and locating the positions of defects in submarine cables. But he is better remembered as the inventor of the Mance heliograph (a wireless solar telegraph that signals by flashes of sunlight using Morse code reflected by a mirror), which found wide military, survey, and forest protection application and for which he was knighted.
