Race Issues in Singapore: The need for greater public discussion | The Online Citizen - 0 views

  • What do we make of MFA’s rejection of free expression and extensive public discussion of race and religion, in light of the PAP government’s reluctance to curb a senior Cabinet member in his freely contentious speech? This points to double standards of the PAP government, or a paternalistic view that ordinary people cannot be trusted to have a mature discussion about these sensitive topics.
  • Yet, the gracious dignity of AMP’s criticism of MM Lee’s comments, and the lively and respectful debate about race issues at Saturday’s forum is indication that Singaporeans can certainly handle public debate about difficult issues–and even if some of us cannot, we need to learn, not by shutting up, but by emulating good examples of genuine debate in public arenas.

journalism.sg » Racial and religious offence: Why censorship doesn't cut it - 1 views

  • All societies use a mix of approaches to address offensive speech. In international law, like at the European court of human rights and more and more jurisdictions, there is growing feeling that the law should really be a last resort and only used for the most extreme speech – speech that incites violence in a very direct way, or that is part of a campaign that violates the rights of minorities to live free of discrimination. In contrast, simply insulting and offending others, even if feelings are very hurt, is not seen as something that should invite a legal response. Using the law to protect feelings is too great an encroachment on freedom of speech.
  • Our laws are written very broadly, such that any sort of offence, even if it does not threaten imminent violence, is seen as deserving of strict regulation. This probably reflects a very strong social consensus that race and religion should be handled delicately. So we tend to rely on strong government. The state protects racial and religious sensibilities from offence, using censorship when there’s a danger of words and actions causing hurt.
  • in almost all cases, state action was instigated by complaints from members of the public. This is quite unlike political censorship, where action is initiated by the government, often with great resistance and opposition from netizens. In a string of cases involving racial and religious offence, however, it’s the netizens who tend to demand action, sometimes acting like a lynch mob.

  • in many cases, the offensive messages were spread further by those reporting the offence.
  • What is the justification for strong police action against any form of speech? Why do we sometimes feel that it may not be enough to counter bad speech with good speech in free and open debate, and that we must instead use the law to stop the bad speech? Surely, it must be because we think the bad speech is so dangerous that it can cause immediate harm; or because we don’t trust the public to respond rationally, so we don’t know if good speech would indeed triumph in open debate. Usually, if we call in the authorities, it must be because we have a mental picture of offensive speech being like lighting a match in a combustible atmosphere. It is dangerous and there’s no time to debate the merits of that match – we just have to put it out. The irony of most of the cases that we have seen in the past few years is that the people demanding government action, as if the offensive words were explosive, were also those who helped to spread them. It is like helping to spread a fire while calling for the fire brigade.
  • their act of spreading the offensive content must mean that they did not actually believe that the expression was really that dangerous in the sense of prompting violence through reprisal attacks or riots. In reposting the offensive words or pictures, they showed that they actually trusted the public enough to respond sympathetically – they had faith that enough people would add their voices to the outrage that they themselves felt when they saw the offensive images or videos or words.
  • This then raises the question, why the need to involve the police at all? If Singaporeans are grown-up enough to defend their society against offensive speech, why have calls for prosecution and censorship become the automatic response? I wonder if this is an example of the well-known habit of unthinkingly relying on government to solve all our problems even when, with a little bit of effort in the form of grassroots action can do the job.
  • The next time people encounter racist or religiously offensive speech, it would be nice to see swift responses from credible and respected civil society groups, Members of Parliament, and other ordinary citizens. If the speaker doesn’t get the message, organise boycotts, for example, and give him or her the clear message that our society isn’t going to take such offence lying down. The more we can respond ourselves through open debate and grassroots action, without the need to ask law and order to step in, the stronger our society will be.
  •  
    No matter how hard we work at developing media literacy, we should not expect to be rid of all racially offensive speech online. There are two broad ways to respond to these breaches. We can reach out horizontally and together with our fellow citizens repair the damage by persuading others to reject harmful ideas. Or, we can reach up vertically to government, getting the authorities to act against irresponsible speech by using the law. The advantage of the latter is that it seems more efficient, punishing those who cross the line of acceptability and violate social norms, and deterring others from doing the same. The horizontal approach works through persuasion rather than the law, so it is slower and not foolproof.

No Science please, we're Anthropologists « Critical Thinking « Skeptic North - 0 views

  • The debate is between researchers in science-based anthropological disciplines like archaeologists, physical anthropology and forensic anthropology — and anthropologists who focus on the more humanities based issues like race, ethnicity and gender.
  • Those that are defend the old mandate, members of the fields that are science based, are interested in relying on the scientific method to inform their theories about anthropology and ensuring that due diligence is done on new theories and that research is being conducted based on sound principles. In opposition are members who view themselves as advocates and activists. As they see it, research on culture, race, and gender is only harmed by science as it represents the cold arm of colonial imperialism.
  • viewing this as more than a simple cosmetic change, he compared the attacks and challenges on anthropology to creationism in that they both are “based on the rejection of rational argument and thought.
  • ...6 more annotations...
  • the American Anthropological Association attempted to clarify their position, they issued a statement in which they stated: “the Executive Board recognizes and endorses the crucial place of the scientific method in much anthropological research.” To further clarify matters they went on to describe anthropology as: “Anthropology is a holistic and expansive discipline that covers the full breadth of human history and culture.”
  • Damon Dozier, the association’s director of public affairs is further quoted saying “We mean holistic in terms of the diversity of the discipline.”
  • Despite the attempts to head off a huge rift, there appears to be lingering doubt as to the direction the American Anthropological Association is going and even more concern that the field of anthropology is under siege from post-modern attacks on its science foundations.
  • One of the most important contributions of science to the world has been a method of inquiry that has proven itself unequalled in explaining the natural world. The scientific method is, and should, be foundational in any field where the goal is to explain the natural world.
  • The so-called “hard sciences” understand this. Where things get muddled is in the “soft sciences” like anthropology, history, and psychology. For some reason these fields have proven especially vulnerable to post-modernism and have fallen prey to schizophrenic notion that science is “western” and trying to use science to explain things is another branch of imperialism.
  • The so-called “soft sciences” are occasionally put in the position of making assumptions. When you have a hypothesis you want to test, you unfortunately can’t travel back in time and do an experiment. Therefore, relying on the evidence you already have and employing your critical thinking skills you formulate a rational assumption and await the opportunity to confirm or deny it. It’s not based on a “hunch” or conjured up from the imagination. It’s based on rational skepticism.

Roger Pielke Jr.'s Blog: Ideological Diversity in Academia - 0 views

  • Jonathan Haidt's talk (above) at the annual meeting of the Society for Personality and Social Psychology was written up last week in a column by John Tierney in the NY Times.  This was soon followed by a dismissal of the work by Paul Krugman.  The entire sequence is interesting, but for me the best part, and the one that gets to the nub of the issue, is Haight's response to Krugman: My research, like so much research in social psychology, demonstrates that we humans are experts at using reasoning to find evidence for whatever conclusions we want to reach. We are terrible at searching for contradictory evidence. Science works because our peers are so darn good at finding that contradictory evidence for us. Social science — at least my corner of it — is broken because there is nobody to look for contradictory evidence regarding sacralized issues, particularly those related to race, gender, and class. I urged my colleagues to increase our ideological diversity not for any moral reason, but because it will make us better scientists. You do not have that problem in economics where the majority is liberal but there is a substantial and vocal minority of libertarians and conservatives. Your field is healthy, mine is not. Do you think I was wrong to call for my professional organization to seek out a modicum of ideological diversity?
  • On a related note, the IMF review of why the institution failed to warn of the global financial crisis identified a lack of intellectual diversity as being among the factors responsible (PDF): Several cognitive biases seem to have played an important role. Groupthink refers to the tendency among homogeneous, cohesive groups to consider issues only within a certain paradigm and not challenge its basic premises (Janis, 1982). The prevailing view among IMF staff—a cohesive group of macroeconomists—was that market discipline and self-regulation would be sufficient to stave off serious problems in financial institutions. They also believed that crises were unlikely to happen in advanced economies, where “sophisticated” financial markets could thrive safely with minimal regulation of a large and growing portion of the financial system.Everyyone in academia has seen similar dynamics at work.

Harvard professor spots Web search bias - Business - The Boston Globe - 0 views

  • Sweeney said she has no idea why Google searches seem to single out black-sounding names. There could be myriad issues at play, some associated with the software, some with the people searching Google. For example, the more often searchers click on a particular ad, the more frequently it is displayed subsequently. “Since we don’t know the reason for it,” she said, “it’s hard to say what you need to do.”
  • But Danny Sullivan, editor of SearchEngineLand.com, an online trade publication that tracks the Internet search and advertising business, said Sweeney’s research has stirred a tempest in a teapot. “It looks like this fairly isolated thing that involves one advertiser.” He also said that the results could be caused by black Google users clicking on those ads as much as white users. “It could be that black people themselves could be causing the stuff that causes the negative copy to be selected more,” said Sullivan. “If most of the searches for black names are done by black people . . . is that racially biased?”
  • On the other hand, Sullivan said Sweeney has uncovered a problem with online searching — the casual display of information that might put someone in a bad light. Rather than focusing on potential instances of racism, he said, search services such as Google might want to put more restrictions on displaying negative information about anyone, black or white.

The meritocratic route to oblivion « Yawning Bread on Wordpress - 0 views

  • Part of the problem with meritocracy is that it homogenizes in the name of diversity: It skims the cream from every race and class and population, puts all of the best and brightest through the same educational conveyor belt, and comes out with a ruling class that’s cosmetically diverse but intellectually conformist, and that tends to huddle together rather than spreading out to enrich the country as a whole.

5 Great Men Who Built Their Careers on Plagiarism | Cracked.com - 1 views

  • Ambrose invented pop history. He was the historical advisor on Saving Private Ryan and wrote the book Band of Brothers, that miniseries about WWII that starred the guy from Office Space.
  • In 1995, an almost unknown historian named Thomas Childers published the book Wings of Morning. It was a well-received but relatively obscure novel about the crew of a specific B-24 bomber during WWII. Ambrose was a fan of the book and, as a firm believer that imitation is the sincerest form of flattery, he proceeded to plagiarize the fuck out of it for his hit 2001 novel, The Wild Blue, which was the account of a different group of B-24 crewmen. Ambrose ripped off whole passages of text and stole several sentences and descriptions word for word. Then he got his book published and just sort of hoped no one would notice.
  • but fortunately for truth, he got caught. Fred Barnes of the Weekly Standard noticed what was going on and revealed it to the world. Ambrose was fast to respond. He had cited Childers' book in his bibliography (although he hadn't come close to listing everything he 'borrowed' from his fellow historian's work) and basically claimed that he'd just "forgotten" to attribute the stolen passages in the text, like he was supposed to.

  • For a little while, Stephen's apology was enough.
  • Mark Lewis, of Forbes.com, was not one of those people. He read the first story about Ambrose and, like a good investigative journalist, proceeded to tear apart everything the pop historian had written in his search for the truth.
  • he found several blatant thefts in the book Crazy Horse and Custer, which Ambrose pretended to write in 1995. For that novel, Ambrose molested the work of esteemed historical writer Jay Monagham. Here's an excerpt from the Forbes article: MONAGHAM: "On August 28, 1859, Custer returned to West Point. Cadet James Barroll Washington, a great-great-grandnephew of George Washington, entered that year. He remembered hearing the crowd shout, 'Here comes Custer!' The name meant nothing to him, but he turned, and saw a slim, immature lad with unmilitary figure, slightly rounded shoulders, and gangling walk." AMBROSE: "When he returned to West Point, Cadet James B. Washington, a relative of George Washington, remembered hearing the crowd shout, 'Here comes Custer!' The name meant nothing to Washington, who was just entering the Academy, but he turned and saw a slim, immature lad with unmilitary figure, slightly rounded shoulders, and gangling walk, surrounded by back-slapping, laughing friends."
  • n total, seven of his books were found to contain some degree of plagiarism. His fucking college thesis was even loaded down with other people's unattributed writing. The most famous historian in the world built his career on a foundation of deception. Did He Pay? He really didn't. Evidence of his wrongdoing came up very shortly before his death from lung cancer in 2002.
  • T.S. Eliot wrote several great, enduring poems, such as "The Love Song of J. Alfred Prufrock" which had a ridiculous title, and "The Hollow Men," which, we were depressed to discover, wasn't about a naked, invisible, murdering lunatic. Perhaps his greatest work was a poem entitled, "The Waste Land," which was a haunting statement of his disillusionment with the post-war era. It was a literary milestone, and is still celebrated today as one of the greatest works of poetry in history.
  • The problem with this is that Eliot didn't write "The Waste Land." Not all of it anyway. As it turns out, the idea behind "The Waste Land," and a fair amount of its content, was plagiarized from an almost unknown American poet named Madison Cawein.
  • Cawein worked hard all of his youth, scrimping and saving and putting aside enough money so that he could begin finally working on his true love: poetry. He put out several volumes of work that is very well regarded, but he never gained any recognition and died almost unknown. Which just goes to show you that, if you work hard in this country and believe in yourself, you'll die alone and under appreciated.
  • Madison Cawein wasn't the only person Eliot stole from. This passage from "The Waste Land:" "The Chair she sat in, like a burnished throne / Glowed on the marble," was slightly altered but still stolen from Shakespeare, who wrote, "The barge she sat in, like a burnish'd throne / Burn'd on the water". Eliot's line, "Sweet Thames, run softly, till I end my song," was stolen entirely from Edmund Spenser's "Prothalamion."
  • Most of "The Waste Land" was just cobbled together out of quotes from other writers. Until very recently, most scholars have been happy to simply chalk these up as "allusions" to the work of other authors. For a long time, it was regarded as something poets just did, as a way of honoring their influences.
  • Did He Pay? "Immature poets imitate; mature poets steal" This is a quote from Eliot himself. You see, T.S. was rich, famous and beloved the world over. While he was alive, everyone just sort of ignored all of the evidence that he was a tremendous bastard. He died renowned as one of the greatest poets in all of history, which he was, but he was also a plagiarizing cockbag who denied a much worthier artist a place in history.
  • We're not saying that King wasn't an incredible person who did more to advance the human race
  • For starters, his own university admits that his doctoral thesis, the very foundation of his career, was significantly plagiarized.
  • Despite clear findings of plagiarism, the committee did not recommend he be posthumously stripped of his title, due to Dr. King's incredible services to the world. And due to their extreme fear of being beaten and castrated by hordes of angry MLK groupies.
  • Not only was his dissertation plagiarized, but many of his student papers and sermons were stolen in whole or in part from other writers. The staff of the King Paper's Project at Stanford even admits that, "King's plagiarism was a general pattern evident in nearly all of his academic writings." Is That All? Perhaps the most notable example of King's plagiarism was the general tone, and several select lines from his famous "I Have a Dream," speech. Theodore Pappas presents a detailed accusation in his book, Plagiarism and the Culture War. Most of the issue centers around the closing lines.
  • Did He Pay? Not during his lifetime. To be fair, it takes balls to accuse the greatest civil rights activist in history with plagiarism.

Why Are the Rich So Good at the Internet? | Fast Company - 0 views

  • It even suggests the existence of a tipping point, where Internet use takes off at a certain income level.
  • even among groups that own the necessary technology, less wealth equates to less (and less varied) Internet usage.
  • The report, an umbrella analysis of three Pew surveys conducted in 2009 and 2010, compares Internet use among American households in four different income brackets: less than $30,000 a year; $30,000-50,000; $50,000-75,000; and greater than $75,000. Respondents--more than 3,000 people participated--were asked a variety of questions about how often they used the Internet, and what sorts of services they took advantage of (such as email, online news, booking travel online, or health research).
  • ...7 more annotations...
  • As might be expected, the wealthier used the Internet more.
  • Almost 90% of the wealthiest respondents reported broadband access at home. Of those in the under-$30,000 households, that figure was only 40%. "I would expect some type of correlation," says Jansen. "But we controlled for community type--urban, rural, suburban--educational attainment, race, ethnicity, gender, and age." None was nearly so strongly correlated as income.
  • Age did have some effect, and rural regions were a good deal less wired
  • Once a modestly middle-class family buys a computer and Internet access, why is it that they spend less time researching products online than their wealthier counterparts, given that they have a tighter budget than the ultra-wealthy?
  • Jansen notes that for many questions Pew asked about Internet use, there appeared to be a tipping point somewhere in the $30,000-$50,000 range. Consider, for instance, the data on those who researched products online. Only 67% of lowest-income Internet users research products online. Make it over the hump into the $30,000-$50,000 bracket, though, and all of a sudden 81% of internet users do so--a jump of 14 points. But then as you climb the income ladder, the change in behavior begins to level out, just climbing a few percentage points with each bracket
  • "It would be interesting to look at what is going on at that particular income level," says Jansen, suggesting a potential tack for further research, "that seems to indicate a fairly robust use of technology and interest."
  • Jansen, like any careful researcher, cautions against confusing correlation with causation. It may be that people are using the web to make their fortunes, and not using their fortunes to surf the web.

    Pew Internet has released a report finding that income is the strongest predictor of whether, how often, and in what ways Americans use the web.

Epiphenom: The evolution of dissent - 0 views

  • Genetic evolution in humans occurs in an environment shaped by culture - and culture, in turn is shaped by genetics.
  • If religion is a virus, then perhaps the spread of religion can be understood through the lens of evolutionary theory. Perhaps cultural evolution can be modelled using the same mathematical tools applied to genetic evolution.
  • Michael Doebli and Iaroslav Ispolatov at the University of  British Columbia
  • ...6 more annotations...
  • set out to model was the development of religious schisms. Such schisms are a recurrent feature of religion, especially in the West. The classic example is the fracturing of Christianity that occured after the reformation.
  • Their model made two simple assumptions. Firstly, that religions that are highly dominant actually induce some people to want to break away from them. When a religion becomes overcrowded, then some individuals will lose their religion and take up another.
  • Second, they assume that every religion has a value to the individual that is composed of it's costs and benefits. That value varies between religion, but is the same for all individuals. It's a pretty simplistic assumption, but even so they get some interesting results.
  • Now, this is a very simple model, and so the results shouldn't be over-interpreted. But it's a fascinating result for a couple of reasons. It shows how new religious 'species' can come into being in a mixed population - no need for geographical separation. That's such a common feature of religion - from the Judaeo-Christian religions to examples from Papua New Guinea - that it's worth trying to understand what drives it. What's more, this is the first time that anyone has attempted to model the transmission of religious ideas in evolutionary terms. It's a first step, to be sure, but just showing that it can be done is a significant achievement.
  • The value comes because it shifts the focus from thinking about how culture benefits the host, and instead asks how the cultural trait is adaptive in it's own right. What is important is not whether or not the human host benefits from the trait, but rather whether the trait can successfully transmit and reproducing itself (see Bible Belter for an example of how this could work).
  • Even more intriguing is the implications for understanding cultural-genetic co-evolution. After all, we know that viruses and their hosts co-evolve in a kind of arms race - sometimes ending up in a relationship that benefits both.

Rationally Speaking: Studying folk morality: philosophy, psychology, or what? - 0 views

  • in the magazine article Joshua mentions several studies of “folk morality,” i.e. of how ordinary people think about moral problems. The results are fascinating. It turns out that people’s views are correlated with personality traits, with subjects who score high on “openness to experience” being reliably more relativists than objectivists about morality (I am not using the latter term in the infamous Randyan meaning here, but as Knobe does, to indicate the idea that morality has objective bases).
  • Other studies show that people who are capable of considering multiple options in solving mathematical puzzles also tend to be moral relativists, and — in a study co-authored by Knobe himself — the very same situation (infanticide) was judged along a sliding scale from objectivism to relativism depending on whether the hypothetical scenario involved a fellow American (presumably sharing our same general moral values), the member of an imaginary Amazonian tribe (for which infanticide was acceptable), and an alien from the planet Pentar (belonging to a race whose only goal in life is to turn everything into equilateral pentagons, and killing individuals that might get in the way of that lofty objective is a duty). Oh, and related research also shows that young children tend to be objectivists, while young adults are usually relativists — but that later in life one’s primordial objectivism apparently experiences a comeback.
  • This is all very interesting social science, but is it philosophy? Granted, the differences between various disciplines are often not clear cut, and of course whenever people engage in truly inter-disciplinary work we should simply applaud the effort and encourage further work. But I do wonder in what sense, if any, the kinds of results that Joshua and his colleagues find have much to do with moral philosophy.
  • ...6 more annotations...
  • there seems to me the potential danger of confusing various categories of moral discourse. For instance, are the “folks” studied in these cases actually relativist, or perhaps adherents to one of several versions of moral anti-realism? The two are definitely not the same, but I doubt that the subjects in question could tell the difference (and I wouldn’t expect them to, after all they are not philosophers).
  • why do we expect philosophers to learn from “folk morality” when we do not expect, say, physicists to learn from folk physics (which tends to be Aristotelian in nature), or statisticians from people’s understanding of probability theory (which is generally remarkably poor, as casino owners know very well)? Or even, while I’m at it, why not ask literary critics to discuss Shakespeare in light of what common folks think about the bard (making sure, perhaps, that they have at least read his works, and not just watched the movies)?
  • Hence, my other examples of stat (i.e., math) and literary criticism. I conceive of philosophy in general, and moral philosophy in particular, as more akin to a (science-informed, to be sure) mix between logic and criticism. Some moral philosophy consists in engaging an “if ... then” sort of scenario, akin to logical-mathematical thinking, where one begins with certain axioms and attempts to derive the consequences of such axioms. In other respects, moral philosophers exercise reflective criticism concerning those consequences as they might be relevant to practical problems.
  • For instance, we may write philosophically about abortion, and begin our discussion from a comparison of different conceptions of “person.” We might conclude that “if” one adopts conception X of what a person is, “then” abortion is justifiable under such and such conditions; while “if” one adopts conception Y of a person, “then” abortion is justifiable under a different set of conditions, or not justifiable at all. We could, of course, back up even further and engage in a discussion of what “personhood” is, thus moving from moral philosophy to metaphysics.
  • Nowhere in the above are we going to ask “folks” what they think a person is, or how they think their implicit conception of personhood informs their views on abortion. Of course people’s actual views on abortion are crucial — especially for public policy — and they are intrinsically interesting to social scientists. But they don’t seem to me to make much more contact with philosophy than the above mentioned popular opinions on Shakespeare make contact with serious literary criticism. And please, let’s not play the cheap card of “elitism,” unless we are willing to apply the label to just about any intellectual endeavor, in any discipline.
  • There is one area in which experimental philosophy can potentially contribute to philosophy proper (as opposed to social science). Once we have a more empirically grounded understanding of what people’s moral reasoning actually is, then we can analyze the likely consequences of that reasoning for a variety of societal issues. But now we would be doing something more akin to political than moral philosophy.
  •  
    My colleague Joshua Knobe at Yale University recently published an intriguing article in The Philosopher's Magazine about the experimental philosophy of moral decision making. Joshua and I have had a nice chat during a recent Rationally Speaking podcast dedicated to experimental philosophy, but I'm still not convinced about the whole enterprise.

How We Know by Freeman Dyson | The New York Review of Books - 0 views

  • Another example illustrating the central dogma is the French optical telegraph.
  • The telegraph was an optical communication system with stations consisting of large movable pointers mounted on the tops of sixty-foot towers. Each station was manned by an operator who could read a message transmitted by a neighboring station and transmit the same message to the next station in the transmission line.
  • The distance between neighbors was about seven miles. Along the transmission lines, optical messages in France could travel faster than drum messages in Africa. When Napoleon took charge of the French Republic in 1799, he ordered the completion of the optical telegraph system to link all the major cities of France from Calais and Paris to Toulon and onward to Milan. The telegraph became, as Claude Chappe had intended, an important instrument of national power. Napoleon made sure that it was not available to private users.
  • ...27 more annotations...
  • Unlike the drum language, which was based on spoken language, the optical telegraph was based on written French. Chappe invented an elaborate coding system to translate written messages into optical signals. Chappe had the opposite problem from the drummers. The drummers had a fast transmission system with ambiguous messages. They needed to slow down the transmission to make the messages unambiguous. Chappe had a painfully slow transmission system with redundant messages. The French language, like most alphabetic languages, is highly redundant, using many more letters than are needed to convey the meaning of a message. Chappe’s coding system allowed messages to be transmitted faster. Many common phrases and proper names were encoded by only two optical symbols, with a substantial gain in speed of transmission. The composer and the reader of the message had code books listing the message codes for eight thousand phrases and names. For Napoleon it was an advantage to have a code that was effectively cryptographic, keeping the content of the messages secret from citizens along the route.
  • After these two historical examples of rapid communication in Africa and France, the rest of Gleick’s book is about the modern development of information technolog
  • The modern history is dominated by two Americans, Samuel Morse and Claude Shannon. Samuel Morse was the inventor of Morse Code. He was also one of the pioneers who built a telegraph system using electricity conducted through wires instead of optical pointers deployed on towers. Morse launched his electric telegraph in 1838 and perfected the code in 1844. His code used short and long pulses of electric current to represent letters of the alphabet.
  • Morse was ideologically at the opposite pole from Chappe. He was not interested in secrecy or in creating an instrument of government power. The Morse system was designed to be a profit-making enterprise, fast and cheap and available to everybody. At the beginning the price of a message was a quarter of a cent per letter. The most important users of the system were newspaper correspondents spreading news of local events to readers all over the world. Morse Code was simple enough that anyone could learn it. The system provided no secrecy to the users. If users wanted secrecy, they could invent their own secret codes and encipher their messages themselves. The price of a message in cipher was higher than the price of a message in plain text, because the telegraph operators could transcribe plain text faster. It was much easier to correct errors in plain text than in cipher.
  • Claude Shannon was the founding father of information theory. For a hundred years after the electric telegraph, other communication systems such as the telephone, radio, and television were invented and developed by engineers without any need for higher mathematics. Then Shannon supplied the theory to understand all of these systems together, defining information as an abstract quantity inherent in a telephone message or a television picture. Shannon brought higher mathematics into the game.
  • When Shannon was a boy growing up on a farm in Michigan, he built a homemade telegraph system using Morse Code. Messages were transmitted to friends on neighboring farms, using the barbed wire of their fences to conduct electric signals. When World War II began, Shannon became one of the pioneers of scientific cryptography, working on the high-level cryptographic telephone system that allowed Roosevelt and Churchill to talk to each other over a secure channel. Shannon’s friend Alan Turing was also working as a cryptographer at the same time, in the famous British Enigma project that successfully deciphered German military codes. The two pioneers met frequently when Turing visited New York in 1943, but they belonged to separate secret worlds and could not exchange ideas about cryptography.
  • In 1945 Shannon wrote a paper, “A Mathematical Theory of Cryptography,” which was stamped SECRET and never saw the light of day. He published in 1948 an expurgated version of the 1945 paper with the title “A Mathematical Theory of Communication.” The 1948 version appeared in the Bell System Technical Journal, the house journal of the Bell Telephone Laboratories, and became an instant classic. It is the founding document for the modern science of information. After Shannon, the technology of information raced ahead, with electronic computers, digital cameras, the Internet, and the World Wide Web.
  • According to Gleick, the impact of information on human affairs came in three installments: first the history, the thousands of years during which people created and exchanged information without the concept of measuring it; second the theory, first formulated by Shannon; third the flood, in which we now live
  • The event that made the flood plainly visible occurred in 1965, when Gordon Moore stated Moore’s Law. Moore was an electrical engineer, founder of the Intel Corporation, a company that manufactured components for computers and other electronic gadgets. His law said that the price of electronic components would decrease and their numbers would increase by a factor of two every eighteen months. This implied that the price would decrease and the numbers would increase by a factor of a hundred every decade. Moore’s prediction of continued growth has turned out to be astonishingly accurate during the forty-five years since he announced it. In these four and a half decades, the price has decreased and the numbers have increased by a factor of a billion, nine powers of ten. Nine powers of ten are enough to turn a trickle into a flood.
  • Gordon Moore was in the hardware business, making hardware components for electronic machines, and he stated his law as a law of growth for hardware. But the law applies also to the information that the hardware is designed to embody. The purpose of the hardware is to store and process information. The storage of information is called memory, and the processing of information is called computing. The consequence of Moore’s Law for information is that the price of memory and computing decreases and the available amount of memory and computing increases by a factor of a hundred every decade. The flood of hardware becomes a flood of information.
  • In 1949, one year after Shannon published the rules of information theory, he drew up a table of the various stores of memory that then existed. The biggest memory in his table was the US Library of Congress, which he estimated to contain one hundred trillion bits of information. That was at the time a fair guess at the sum total of recorded human knowledge. Today a memory disc drive storing that amount of information weighs a few pounds and can be bought for about a thousand dollars. Information, otherwise known as data, pours into memories of that size or larger, in government and business offices and scientific laboratories all over the world. Gleick quotes the computer scientist Jaron Lanier describing the effect of the flood: “It’s as if you kneel to plant the seed of a tree and it grows so fast that it swallows your whole town before you can even rise to your feet.”
  • On December 8, 2010, Gleick published on the The New York Review’s blog an illuminating essay, “The Information Palace.” It was written too late to be included in his book. It describes the historical changes of meaning of the word “information,” as recorded in the latest quarterly online revision of the Oxford English Dictionary. The word first appears in 1386 a parliamentary report with the meaning “denunciation.” The history ends with the modern usage, “information fatigue,” defined as “apathy, indifference or mental exhaustion arising from exposure to too much information.”
  • The consequences of the information flood are not all bad. One of the creative enterprises made possible by the flood is Wikipedia, started ten years ago by Jimmy Wales. Among my friends and acquaintances, everybody distrusts Wikipedia and everybody uses it. Distrust and productive use are not incompatible. Wikipedia is the ultimate open source repository of information. Everyone is free to read it and everyone is free to write it. It contains articles in 262 languages written by several million authors. The information that it contains is totally unreliable and surprisingly accurate. It is often unreliable because many of the authors are ignorant or careless. It is often accurate because the articles are edited and corrected by readers who are better informed than the authors
  • Jimmy Wales hoped when he started Wikipedia that the combination of enthusiastic volunteer writers with open source information technology would cause a revolution in human access to knowledge. The rate of growth of Wikipedia exceeded his wildest dreams. Within ten years it has become the biggest storehouse of information on the planet and the noisiest battleground of conflicting opinions. It illustrates Shannon’s law of reliable communication. Shannon’s law says that accurate transmission of information is possible in a communication system with a high level of noise. Even in the noisiest system, errors can be reliably corrected and accurate information transmitted, provided that the transmission is sufficiently redundant. That is, in a nutshell, how Wikipedia works.
  • The information flood has also brought enormous benefits to science. The public has a distorted view of science, because children are taught in school that science is a collection of firmly established truths. In fact, science is not a collection of truths. It is a continuing exploration of mysteries. Wherever we go exploring in the world around us, we find mysteries. Our planet is covered by continents and oceans whose origin we cannot explain. Our atmosphere is constantly stirred by poorly understood disturbances that we call weather and climate. The visible matter in the universe is outweighed by a much larger quantity of dark invisible matter that we do not understand at all. The origin of life is a total mystery, and so is the existence of human consciousness. We have no clear idea how the electrical discharges occurring in nerve cells in our brains are connected with our feelings and desires and actions.
  • Even physics, the most exact and most firmly established branch of science, is still full of mysteries. We do not know how much of Shannon’s theory of information will remain valid when quantum devices replace classical electric circuits as the carriers of information. Quantum devices may be made of single atoms or microscopic magnetic circuits. All that we know for sure is that they can theoretically do certain jobs that are beyond the reach of classical devices. Quantum computing is still an unexplored mystery on the frontier of information theory. Science is the sum total of a great multitude of mysteries. It is an unending argument between a great multitude of voices. It resembles Wikipedia much more than it resembles the Encyclopaedia Britannica.
  • The rapid growth of the flood of information in the last ten years made Wikipedia possible, and the same flood made twenty-first-century science possible. Twenty-first-century science is dominated by huge stores of information that we call databases. The information flood has made it easy and cheap to build databases. One example of a twenty-first-century database is the collection of genome sequences of living creatures belonging to various species from microbes to humans. Each genome contains the complete genetic information that shaped the creature to which it belongs. The genome data-base is rapidly growing and is available for scientists all over the world to explore. Its origin can be traced to the year 1939, when Shannon wrote his Ph.D. thesis with the title “An Algebra for Theoretical Genetics.
  • Shannon was then a graduate student in the mathematics department at MIT. He was only dimly aware of the possible physical embodiment of genetic information. The true physical embodiment of the genome is the double helix structure of DNA molecules, discovered by Francis Crick and James Watson fourteen years later. In 1939 Shannon understood that the basis of genetics must be information, and that the information must be coded in some abstract algebra independent of its physical embodiment. Without any knowledge of the double helix, he could not hope to guess the detailed structure of the genetic code. He could only imagine that in some distant future the genetic information would be decoded and collected in a giant database that would define the total diversity of living creatures. It took only sixty years for his dream to come true.
  • In the twentieth century, genomes of humans and other species were laboriously decoded and translated into sequences of letters in computer memories. The decoding and translation became cheaper and faster as time went on, the price decreasing and the speed increasing according to Moore’s Law. The first human genome took fifteen years to decode and cost about a billion dollars. Now a human genome can be decoded in a few weeks and costs a few thousand dollars. Around the year 2000, a turning point was reached, when it became cheaper to produce genetic information than to understand it. Now we can pass a piece of human DNA through a machine and rapidly read out the genetic information, but we cannot read out the meaning of the information. We shall not fully understand the information until we understand in detail the processes of embryonic development that the DNA orchestrated to make us what we are.
  • The explosive growth of information in our human society is a part of the slower growth of ordered structures in the evolution of life as a whole. Life has for billions of years been evolving with organisms and ecosystems embodying increasing amounts of information. The evolution of life is a part of the evolution of the universe, which also evolves with increasing amounts of information embodied in ordered structures, galaxies and stars and planetary systems. In the living and in the nonliving world, we see a growth of order, starting from the featureless and uniform gas of the early universe and producing the magnificent diversity of weird objects that we see in the sky and in the rain forest. Everywhere around us, wherever we look, we see evidence of increasing order and increasing information. The technology arising from Shannon’s discoveries is only a local acceleration of the natural growth of information.
  • . Lord Kelvin, one of the leading physicists of that time, promoted the heat death dogma, predicting that the flow of heat from warmer to cooler objects will result in a decrease of temperature differences everywhere, until all temperatures ultimately become equal. Life needs temperature differences, to avoid being stifled by its waste heat. So life will disappear
  • Thanks to the discoveries of astronomers in the twentieth century, we now know that the heat death is a myth. The heat death can never happen, and there is no paradox. The best popular account of the disappearance of the paradox is a chapter, “How Order Was Born of Chaos,” in the book Creation of the Universe, by Fang Lizhi and his wife Li Shuxian.2 Fang Lizhi is doubly famous as a leading Chinese astronomer and a leading political dissident. He is now pursuing his double career at the University of Arizona.
  • The belief in a heat death was based on an idea that I call the cooking rule. The cooking rule says that a piece of steak gets warmer when we put it on a hot grill. More generally, the rule says that any object gets warmer when it gains energy, and gets cooler when it loses energy. Humans have been cooking steaks for thousands of years, and nobody ever saw a steak get colder while cooking on a fire. The cooking rule is true for objects small enough for us to handle. If the cooking rule is always true, then Lord Kelvin’s argument for the heat death is correct.
  • the cooking rule is not true for objects of astronomical size, for which gravitation is the dominant form of energy. The sun is a familiar example. As the sun loses energy by radiation, it becomes hotter and not cooler. Since the sun is made of compressible gas squeezed by its own gravitation, loss of energy causes it to become smaller and denser, and the compression causes it to become hotter. For almost all astronomical objects, gravitation dominates, and they have the same unexpected behavior. Gravitation reverses the usual relation between energy and temperature. In the domain of astronomy, when heat flows from hotter to cooler objects, the hot objects get hotter and the cool objects get cooler. As a result, temperature differences in the astronomical universe tend to increase rather than decrease as time goes on. There is no final state of uniform temperature, and there is no heat death. Gravitation gives us a universe hospitable to life. Information and order can continue to grow for billions of years in the future, as they have evidently grown in the past.
  • The vision of the future as an infinite playground, with an unending sequence of mysteries to be understood by an unending sequence of players exploring an unending supply of information, is a glorious vision for scientists. Scientists find the vision attractive, since it gives them a purpose for their existence and an unending supply of jobs. The vision is less attractive to artists and writers and ordinary people. Ordinary people are more interested in friends and family than in science. Ordinary people may not welcome a future spent swimming in an unending flood of information.
  • A darker view of the information-dominated universe was described in a famous story, “The Library of Babel,” by Jorge Luis Borges in 1941.3 Borges imagined his library, with an infinite array of books and shelves and mirrors, as a metaphor for the universe.
  • Gleick’s book has an epilogue entitled “The Return of Meaning,” expressing the concerns of people who feel alienated from the prevailing scientific culture. The enormous success of information theory came from Shannon’s decision to separate information from meaning. His central dogma, “Meaning is irrelevant,” declared that information could be handled with greater freedom if it was treated as a mathematical abstraction independent of meaning. The consequence of this freedom is the flood of information in which we are drowning. The immense size of modern databases gives us a feeling of meaninglessness. Information in such quantities reminds us of Borges’s library extending infinitely in all directions. It is our task as humans to bring meaning back into this wasteland. As finite creatures who think and feel, we can create islands of meaning in the sea of information. Gleick ends his book with Borges’s image of the human condition:We walk the corridors, searching the shelves and rearranging them, looking for lines of meaning amid leagues of cacophony and incoherence, reading the history of the past and of the future, collecting our thoughts and collecting the thoughts of others, and every so often glimpsing mirrors, in which we may recognize creatures of the information.

Roger Pielke Jr.'s Blog: Every Relatively Affluent White Guy for Himself - 0 views

  • one of the big arguments that environmentalists have used about the need to stop climate change is that those who will suffer most are the little brown poor people in far-off lands who will, for instance, experience increased incidence of malaria and exposure to floods and other disasters. (Of course the fact that they are already burdened by such things in huge disproportion to the privileged minority doesn’t seem to enter into the argument).
  • But I raise this point because when it comes to climate survivalism, the little brown folks are nowhere to be seen, and apparently it’s every relatively affluent white guy (and his nuclear family, of course) for himself.
  • Dan Sarewitz takes the Washington Post to task for publishing a bizarre commentary on the coming climate apocalypse: Check out the article by a climate survivalist from the February 27, 2011 Washington Post. (I’m going to go out on a limb and treat the article as if it’s not a satire or hoax, but maybe the joke’s on me.) The author describes how he’s buying solar panels and generators and laying in food and supplies and putting extra locks on his doors and windows in anticipation of the coming climate apocalypse, much in the way that in the 1960s certain nuts were digging shelters in their backyard to provide protection against hydrogen bombs, and in the ‘80s (and probably to this day) right-wing crazies were building up small arsenals to protect themselves against the time when the government tried to take away their right to be bigots.

  • fear of the coming apocalypse seems to be an honorable tradition among some factions of the human race, and besides in this case it’s probably good for the beleaguered economy that this guy is spending what must be lots of money on hardware, both high-tech and low. But there are some elements of climate survivalism that are truly troubling. The fact that the Washington Post chose to put this article on the front page of its Sunday opinion section is an editorial judgment that the author, who is executive director of the Chesapeake Climate Action Committee, is someone whose perspective deserves to be taken seriously.

Breakthrough Europe: Emerging Economies Reassert Commitment to Nuclear Power - 0 views

  • Nearly half a billion of India's 1.2 billion citizens continue to live in energy poverty. According to the Chairman of the Indian Atomic Energy Commission, Srikumar Banerjee, "ours is a very power-hungry country. It is essential for us to have further electricity generation." The Chinese have cited similar concerns in sticking to their major expansion plans of its nuclear energy sector. At its current GDP growth, China's electricity demands rise an average of 12 percent per year.
  • the Japanese nuclear crisis demonstrates the vast chasm in political priorities between the developing world and the post-material West.
  • Other regions that have reiterated their plans to stick to nuclear energy are Eastern Europe and the Middle East. The Prime Minister of Poland, the fastest growing country in the EU, has said that "fears of a nuclear disaster in Japan following last Friday's earthquake and tsunami would not disturb Poland's own plans to develop two nuclear plants." Russia and the Czech Republic have also restated their commitment to further nuclear development, while the Times reports that "across the Middle East, countries have been racing to build up nuclear power, as a growth and population boom has created unprecedented demand for energy." The United Arab Emirates is building four plants that will generate roughly a quarter of its power by 2020.
  • ...1 more annotation...
  • Some European leaders, including Angela Merkel, may be backtracking fast on their commitment to nuclear power, but despite yesterday's escalation of the ongoing crisis in Fukushima, Japan, there appear to be no signs that India, China and other emerging economies will succumb to a similar backlash. For the emerging economies, overcoming poverty and insecurity of supply remain the overriding priorities of energy policy.
  •  
    As the New York Times reports: The Japanese disaster has led some energy officials in the United States and in industrialized European nations to think twice about nuclear expansion. And if a huge release of radiation worsens the crisis, even big developing nations might reconsider their ambitious plans. But for now, while acknowledging the need for safety, they say their unmet energy needs give them little choice but to continue investing in nuclear power.

Christina Patterson: Prejudice and the pursuit of 'cool' - Christina Patterson, Comment... - 0 views

  • We're confused because we seem to think that to be black is to be "cool". We seem to think that being black has something to do with playing sport very well, or being very handsome, or very beautiful, or very sexy. We seem to think it has something do with multi-millionaire musicians who make music that uses words like "nigger", "bitch" and "whore". We seem to think, or some people seem to think, that knowing a black person, or having had sex with a black person, is something to boast about to another black person, or even to a white person. Something that will make us look "cool".

Cadbury's Naomi Campbell ad not racist, rules watchdog | Media | guardian.co.uk - 0 views

  • The press ad for Cadbury's Bliss range of Dairy Milk chocolate – which ran with the strapline "move over Naomi, there's a new diva in town" – provoked outrage from the supermodel as well as campaigning group Operation Black Vote.Campbell said she was shocked by the ad, while her mother Valerie said she was "deeply upset by this racist advert".Cadbury initially defended the campaign, saying it was intended as a tongue-in-cheek play on her reputation for diva-style tantrums and had nothing to do with her skin colour.However, after taking took legal advice Cadbury withdrew the campaign and made a public apology on its corporate website.
  • The complainants objected that the ad was racially offensive because it compared a black woman to a bar of chocolate.However, the ASA council said that the ad was "likely to be understood to refer to Naomi Campbell's reputation for 'diva-style' behaviour rather than her race"."On this basis the council decided that the ad was unlikely to be seen as racist or to cause serious or widespread offence," the ASA added.
  •  
    The advertising watchdog has thrown out complaints accusing an ad by Cadbury of racism for comparing model Naomi Campbell to a bar of chocolate. This decision follows an assessment by the council of the Advertising Standards Authority on whether to launch an investigation to see if the press campaign is in breach of the advertising code relating to racism.
