What aliens could learn from the stuff we’ve left in space

Even in space, where none of us live, some of what we’ve left is space junk: stuff orbiting the earth that nobody particularly intended to leave anywhere. But much of what we’ve left in space is intentional. Some of it is symbolic artifacts intended for an audience of people here on Earth - the fallen astronaut, the American flag on the moon, a CD containing a list of over half a million people who wanted to send their names to a comet, courtesy of a NASA probe. In some cases, however, we are also sending a deliberate signal out beyond Earth, to be received by forces unknown. Rather than just listening for radio signals, which has been a staple of the Search for Extraterrestrial Intelligence, some earthlings have become interested in actively reaching out - broadcasting radio messages to anyone, or anything, out there that might be able to hear them. For reasons that are perhaps obvious, these are controversial projects.

Michel Serres: We are in the middle of an extraordinary human and environmental transformation, without really being aware of it, one that can only perhaps be compared with the Renaissance, the fifth century BC, and even the Neolithic age. For example, if there are no more peasants today, when did peasantry ­begin? In the Neolithic age. We can now say that in the year 2000, the Neolithic age is over. But who announced this in the news­papers? We didn’t read in any paper that “the Neolithic age is over”!

And we are equipped in our thinking for this change?

No. What we see are many turning points – physical, environmental, agricul­tural, medical, demographic, etc. All these events are profoundly significant; they touch human life and human behavior, the space around us. In 1800, eight per cent of the population lived in cities, meaning that prior to that, the number was even smaller. Today, 50 to 70 percent of the population is urban. 

Gleick makes his case in a sweeping survey that covers the five millenniums of humanity’s engagement with information, from the invention of writing in Sumer to the elevation of information to a first principle in the sciences over the last half-century or so. It’s a grand narrative if ever there was one, but its key moment can be pinpointed to 1948, when Claude Shannon, a young mathematician with a background in cryptography and telephony, published a paper called “A Mathematical Theory of Communication” in a Bell Labs technical journal. For Shannon, communication was purely a matter of sending a message over a noisy channel so that someone else could recover it. Whether the message was meaningful, he said, was “irrelevant to the engineering problem.” Think of a game of Wheel of Fortune, where each card that’s turned over narrows the set of possible answers, except that here the answer could be anything: a common English phrase, a Polish surname, or just a set of license plate numbers

It is unlikely that Bacon’s cipher system was ever used for the transmission of military secrets, in the seventeenth century or in the twentieth. But for roughly a century from 1850, it set the world of literature on fire. A passion for puzzles, codes, and conspiracies fuelled a widespread suspicion that Shakespeare was not the author of his plays, and professional and amateur scholars of all sorts spent extraordinary amounts of time, energy, and money combing Renaissance texts in search of signatures and other messages that would reveal the true identity of their author. Even after the recent publication of James Shapiro’s comprehensive history of the authorship controversy, Contested Will, it is difficult for us to appreciate the depth of conviction—among writers as diverse and as distinguished as Mark Twain, Walt Whitman, Sigmund Freud, Henry James, Henry Miller, and even Helen Keller—that Shakespeare’s texts contained the secret solution

Jacques Rancière prepares for us a parable. A student who is illiterate, after living a fulfilled life without text, one day decides to teach herself to read. Luckily she knows a single poem by heart and procures a copy of that poem, presumably from a trusted source, by which to work. By comparing her knowledge, sign by sign, word by word, with the poem she can, Rancière believes, finally piece together a foundational understanding of her language: “From this ignoramus, spelling out signs, to the scientist who constructs hypotheses, the same intelligence is always at work – an intelligence that translates signs into other signs and proceeds by comparisons and illustrations in order to communicate its intellectual adventures and understand what another intelligence is endeavoring to communicate to it. This poetic labour of translation is at the heart of all learning.” The Emancipated Spectator (2008)

What interests me in Rancière’s example is not so much the act of translation as the possibility of mis-translation. Taken in light of The Ignorant Schoolmaster we can assume that Rancière is aware of the wide gap that exists between knowing something and knowing enough about something for it to be valuable. But what distinction can we uncover between the ‘true’ and the ‘false’, hell, even between the ‘true’ and ‘almost true’? How does one calculate the value of what is effectively a mistake? Error appears to be a crucial component of Rancière’s position. In a sense, Rancière is positing a world that has from first principles always uncovered itself through a kind of decoding. A world in which subjects “translate signs into other signs and proceed by comparison and illustration”. Now forgive me for side-stepping a little here, but doesn’t that sound an awful lot like biological development? Here’s a paragraph from Richard Dawkins (worth his salt as long as he is talking about biology): “Think about the two qualities that a virus, or any sort of parasitic replicator, demands of a friendly medium, the two qualities that make cellular machinery so friendly towards parasitic DNA, and that make computers so friendly towards computer viruses. These qualities are, firstly, a readiness to replicate information accurately, perhaps with some mistakes that are subsequently reproduced accurately; and, secondly, a readiness to obey instructions encoded in the information so replicated.” Viruses of the Mind (1993)

Hidden amongst Dawkins’ words, I believe, we find an interesting answer to the problem of mis-translation I pose above. A mistake is useless if accuracy is your aim, but what if your aim is merely to learn something? To enrich and expand the connections that exist between your systems of knowledge. As Dawkins alludes to above, it is beneficial for life that errors do exist and are propagated by biological systems. Too many copying errors and all biological processes would be cancerous, mutating towards oblivion. Too much error management (what in information theory would be metered by a coded ‘redundancy‘) and biological change, and thus evolution, could never occur. Simply put, exchange within and between systems is almost valueless unless change, and thus error, is possible within the system. At the scale Rancière exposes for us there are two types of value: firstly, the value of repeating the message (the poem) and secondly, the value of making an error and thus producing entirely new knowledge. In information theory the value of a message is calculated by the amount of work saved on the part of the receiver. That is, if the receiver were to attempt to create that exact message, entirely from scratch. In his influential essay, Encoding, Decoding (1980), Stuart Hall maps a four-stage theory of “linked but distinctive moments” in the circuit of communication:

production circulation use (consumption) reproduction

John Corner further elaborates on these definitions:

the moment of encoding: ‘the institutional practices and organizational conditions and practices of production’; the moment of the text: ‘the… symbolic construction, arrangement and perhaps performance… The form and content of what is published or broadcast’; and the moment of decoding: ‘the moment of reception [or] consumption… by… the reader/hearer/viewer’ which is regarded by most theorists as ‘closer to a form of “construction”‘ than to ‘the passivity… suggested by the term “reception”‘

(source) At each ‘moment’ a new set of limits and possibilities arises. This means that the way a message is coded/decoded is not the only controlling factor in its reception. The intended message I produce, for instance, could be circulated against those intentions, or consumed in a way I never imagined it would be. What’s more, at each stage there emerges the possibility for the message to be replicated incorrectly, or, even more profoundly, for a completely different component of the message to be taken as its defining principle. Let’s say I write a letter, intending to send it to my newly literate, ignoramus friend. The letter contains a recipe for a cake I have recently baked. For some reason my letter is intercepted by the CIA,who are convinced that the recipe is a cleverly coded message for building a bomb. At this stage in the communication cycle the possibility for mis-translation to occur is high. Stuart Hall would claim is that this shows how messages are determined by the social and institutional power-relations via which they are encoded and then made to circulate. Any cake recipe can be a bomb recipe if pushed into the ‘correct’ relationships. Every ignoramus, if they have the right teacher, can develop knowledge that effectively lies beyond the teacher’s. What it is crucial to understand is that work is done at each “moment” of the message. As John Corner states, decoding is constructive: the CIA make the message just as readily as I did when I wrote and sent it. These examples are crude, no doubt, but they set up a way to think about exchange (communication and information) through its relationships, rather than through its mediums and methods. The problem here that requires further examination is thus: What is ‘value’ and how does one define it within a relational model of exchange? Like biological evolution, information theory is devoid of intentionality. Life prospers in error, in noise and mistakes. Perhaps, as I am coming to believe, if we want to maximise the potential of art, of writing and other systems of exchange, we first need to determine their inherent redundancy. Or, more profoundly, to devise ways to maximise or even increase that redundancy. To determine art’s redundancy, and then, like Rancière’s ignoramus, for new knowledge to emerge through mis-translation and mis-relation.

About a month ago in handling the remains of one Dr. Fred McCabe I found rich notes of contemplation on the subject of information theory. It appears that Fred could have written an entire book on the intricacies of hidden data, encoded messages and deceptive methods of transmission. Instead his notes exist in the form of a cryptic assemblage of definitions and examples, arranged into what Dr. McCabe himself labelled a series of ‘moments’.

I offer these moments alongside some of the ten thousand images Dr. McCabe amassed in a separate, but intimately linked, archive. The preface to this abridged compendium is little capable of preparing one for the disarray of material, but by introducing this text with Fred's own words it is my hope that a sense of the larger project will take root in the reader’s fertile imagination.

The Moment of the Message: A Diatribe

by Dr. Fred McCabe

More than ten thousand books on mathematics and a thousand books on philosophy exist for every one upon information. This is surprising. It must mean something.

I want to give you a message. But first. I have to decide how to deliver the message.

This is that moment.

I can write it down, or perhaps memorise it – reciting it in my head like a mantra, a prayer chanted in the Palace gardens. And later, speaking in your ear, I will repeat it to you. That is, if you want to hear it.

I could send it to you, by post, or telegram. After writing it down I will transmit it to you. Broadcasting on your frequency in the hope that you will be tuned in at the right moment. Speaking your language. Encoded and encrypted, only you will understand it.

I have a message for you and I want you to receive it. But first. I have to decide what the message is.

This is that moment:

This is the moment of the message

From the earliest days of information theory it has been appreciated that information per se is not a good measure of message value. The value of a message appears to reside not in its information (its absolutely unpredictable parts) but rather in what might be called its redundancy—parts predictable only with difficulty, things the receiver could in principle have figured out without being told, but only at considerable cost in money, time, or computation. In other words, the value of a message is the amount of work plausibly done by its originator, which its receiver is saved from having to repeat.

This is the moment my water arrived at room temperature

The term enthalpy comes from the Classical Greek prefix en-, meaning "to put into", and the verb thalpein, meaning "to heat".

For a simple system, with a constant number of particles, the difference in enthalpy is the maximum amount of thermal energy derivable from a thermodynamic process in which the pressure is held constant.

This is the moment the wafer became the body of Christ

The Roman Catholic Church got itself into a bit of a mess. Positing God as the victim of the sacrifice introduced a threshold of undecidability between the human and the divine. The simultaneous presence of two natures, which also occurs in transubstantiation, when the bread and wine become the body and blood of Christ, threatens to collapse the divine into the human; the sacred into the profane. The question of whether Christ really is man and God, of whether the wafer really is bread and body, falters between metaphysics and human politics. The Pope, for all his failings, has to decide the undecidable.

This is the moment black lost the game

A ko fight is a tactical and strategic phase that can arise in the game of go.

Some kos offer very little gain for either player. Others control the fate of large portions of the board, sometimes even the whole board, and the outcome of those kos can determine the winner of the game. For this reason, finding and using ko threats well is a very important skill.

This is the moment Robinson Crusoe becomes the first, English language novel

According to Abel Chevalley, a novel is: "a fiction in prose of a certain extent”, defining that "extent" at over 50,000 words. Some critics distinguish the novel from the romance (which has fantastic elements), the allegory (in which characters and events have political, religious or other meanings), and the picaresque (which has a loosely connected sequence of episodes). Some critics have argued that Robinson Crusoe contains elements of all three of these other forms.

This is the moment Sarah Conner takes control

A paper clip is usually a thin wire in a looped shape that takes advantage of the elasticity and strength of the materials of its construction to compress and therefore hold together two or more pieces of paper by means of torsion and friction. Some other kinds of paper clip use a two-piece clamping system.

In fiction, a paper clip often takes the place of a key as means of breaking and entering, or, in Sarah Conner’s case, as means of escape.

This is the moment they found the missing piece of DNA

In northern Spain 49,000 years ago, 11 Neanderthals were murdered. Their tooth enamel shows that each of them had gone through several periods of severe starvation, a condition their assailants probably shared. Cut marks on the bones indicate the people were butchered with stone tools. About 700 feet inside the cave, a research team excavated 1,700 bones from that cannibalistic feast. Much of what is known about Neanderthal genetics comes from those 11 individuals.

This is the moment Bill Clinton lied (to himself)

A microexpression is a brief, involuntary facial expression shown on the face according to emotions experienced. They usually occur in high-stake situations, where people have something to lose or gain. Unlike regular facial expressions, it is difficult to fake microexpressions. Microexpressions express the seven universal emotions: disgust, anger, fear, sadness, happiness, surprise, and contempt. They can occur as fast as 1/25 of a second.

This is the moment I strained my iris

Idiopathic is an adjective used primarily in medicine meaning arising spontaneously or from an obscure or unknown cause. From Greek idios (one's own) and pathos (suffering), it means approximately "a disease of its own kind."

This is the moment everything changed

In ordinary conversation, everything usually refers only to the totality of things relevant to the subject matter. When there is no expressed limitation, everything may refer to the universe or the world.

Every object and entity is a part of everything, including all physical bodies and in some cases all abstract objects. Everything is generally defined as the opposite of nothing, although an alternative view considers "nothing" a part of everything.

This is the moment of another message

In information theory the value of a message is calculated by the cost it would take to repeat or replace the work the message has done.

One might argue that a message’s usefulness is a better measure of value than its replacement cost. Usefulness is an anthropocentric concept that information theorists find difficult to conceptualise.

At the age of 17 he began dissecting corpses from the church graveyard. Between the years 1508 and 1512 he painted the ceiling of the Sistine Chapel in Rome. Michelangelo Buonarroti—known by his first name the world over as the singular artistic genius, sculptor and architect—was also an anatomist, a secret he concealed by destroying almost all of his anatomical sketches and notes. Now, 500 years after he drew them, his hidden anatomical illustrations have been found—painted on the ceiling of the Sistine Chapel, cleverly concealed from the eyes of Pope Julius II and countless religious worshipers, historians, and art lovers for centuries—inside the body of God.

In 1990, physician Frank Meshberger published a paper in the Journal of the American Medical Association deciphering Michelangelo’s imagery with the stunning recognition that the depiction in God Creating Adam in the central panel on the ceiling was a perfect anatomical illustration of the human brain in cross section.
