APOD: 2018 September 9 - Aerosol Earth
"... the Goddard Earth Observing System Forward Processing (GEOS FP) model relies on a combination of Earth-observing satellite and ground-based data to calculate the presence of types of aerosols, tiny solid particles and liquid droplets, as they circulate above the entire planet. This August 23rd model shows black carbon particles in red from combustion processes, like smoke from the fires in the United States and Canada, spreading across large stretches of North America and Africa. Sea salt aerosols are in blue, swirling above threatening typhoons near South Korea and Japan, and the hurricane looming near Hawaii. Dust shown in purple hues is blowing over African and Asian deserts."

Letter to an Aspiring Intellectual by Paul J. Griffiths | Articles | First Things
Via ALD. By Paul J. Griffiths is Warren Professor of Catholic Theology at Duke Divinity School.

"So: Find something to think about that seems to you to have complexity sufficient for long work, sufficient to yield multifaceted and refractory results when held up to thought’s light as jewelers hold gemstones up to their loupes. And then, don’t stop thinking about it."

Purpose of argument: "we argue with those who differ from us, sometimes, it’s true, out of the delight of battle and the urge for victory, but sometimes, too, because we find in argument a powerful device for clarifying a position and seeing how it might be improved."

"I think that at the moment you’re in love with the idea of being an intellectual rather than with some topic for thought. ... Most people who’d love to be novelists don’t write novels, and that’s because they’re not really interested in doing so. They’re infatuated with an image and a rôle rather than with what those who play that rôle do."

"You need a life in which you can spend a minimum of three uninterrupted hours every day, excepting sabbaths and occasional vacations, on your intellectual work. ... You need this because intellectual work is, typically, cumulative and has momentum."

"The most essential skill is surprisingly hard to come by. That skill is attention. Intellectuals always think about something, and that means they need to know how to attend to what they’re thinking about. Attention can be thought of as a long, slow, surprised gaze at whatever it is."

"How then to overcome boredom and cultivate attention? ... There’s no twelve-step for this. Rather, it’s a matter, first, of knowing that attention is necessary for intellectual work and that it will, when practiced, bear unexpected fruit, and that it won’t, no matter what seems to be the case, exhaust what it’s turned to. Then, it’s a matter of knowing that you’ll be bored by what you’re thinking about, ceasing to be surprised by that dry response, and accommodating it into the patterns of your attention (see above, on the relation between solitude and loneliness). And lastly, it’s a matter of practice by repetition, like piano-playing and squash. You’ll get better at attending as you do it, so long as you know you need to get better at it."

"Don’t do any of the things I’ve recommended unless it seems to you that you must. ... Undertake it if, and only if, nothing else seems possible. "

Finding chaos and precision in all things – a philosophy of watchmaking | Aeon Videos
"Filled with the pulses of numerous ticking watch hands, this short documentary from the UK filmmaker Marie-Cécile Embleton profiles a London-based Iranian watchmaker as he muses on the delicate and temporal nature of his work. As Faramarz meticulously polishes wood, shapes metal and positions springs, his personal philosophy emerges – one that values the minutiae of moment-to-moment experiences, and finds craft in all things. Beautifully shot and carefully constructed in a manner that mirrors the work of its subject, The Watchmaker was a film festival favourite in 2017, appearing at the SXSW Film Festival and HotDocs, among others."

BLOOM on Vimeo
In April this year, director Julian Lucas went on holiday to Japan - his camera came with him.

The result is the film Bloom.

He discovered a peculiar sense of quiet, desolation, and loneliness among the people.
In a country so packed with lights and trains and crowds and experiences, from the theatrical to the serene to patently bizarre, Bloom captures this lovely dichotomy between the people and the cities they inhabit. Inside the noise and the chaos, Julian captures people alone, wandering the streets, buried in telephones - a dull, menacing and peaceful nothingness below the surface.

How textiles repeatedly revolutionised human technology - Virginia Postrel
" textiles are technology, more ancient than bronze and as contemporary as nanowires. We hairless apes co-evolved with our apparel. But, to reverse Arthur C Clarke’s adage, any sufficiently familiar technology is indistinguishable from nature." "The ancient Greeks worshiped Athena as the goddess of technē, the artifice of civilisation. She was the giver and protector of olive trees, of ships and of weaving (without which there would be no sails). When she and Odysseus scheme, they ‘weave a plan’. To weave is to devise, to invent – to contrive function and beauty from the simplest of elements." "David Orban proposed that his fellow Bitcoin evangelists adopt ‘weaving’ rather than ‘mining’ as their metaphor for the work of encoding and recording the public ledger of Bitcoin transactions. ‘Weavers,’ he wrote, ‘take the intertwined threads and through their expert, value-added activity create a strong fabric – which is exactly what the global distributed network of computers creating ..."

How to design a metaphor – Michael Erard – Aeon
"Can metaphors be designed? I’m here to tell you that they can, and are. ... I continue to shape and test metaphors for private-sector clients and others. In both cases, these metaphors are meant to help people to understand the unfamiliar. They aren’t supposed to make someone remark: ‘That’s beautiful.’ They’re meant to make someone realise that they’ve only been looking at one side of a thing." - "It was the Princeton psycholinguist Sam Glucksberg who in 2003 argued that metaphors are really categorisation proposals.

Most violence arises from morality, not the lack of it - www.newscientist.com Opinion
"Contrary to popular perception, people are rarely violent simply because they lose control and fail to think about right and wrong. They rarely commit violence because they lack empathy and fail to see their victims as fully human. And almost no one is violent because they draw sadistic pleasure from the suffering of others. Across cultures and history, there is generally one motive for hurting or killing: people are violent because it feels like the right thing to do. They feel morally obliged to do it." "In short, most violence is morally motivated to create, conduct, protect, redress, terminate or mourn crucial relationships, according to the cultural norms of the group that people belong to." "we must reorient potential perpetrators to find non-violent ways to regulate their relationships. Moreover, we must make perpetrators know that their violent actions will violate their relationships with people they care about. "

Why God Will Not Die - Jack Miles, The Atlantic, 17 Nov 2014
"In my 20s, I was a sucker for such stuff. Worse, I was painfully slow to notice my own posing. Only after the passage of some time and the small, salutary shock of having my wallet stolen did I examine these three professions of secular faith and realize, with an inward blush, that what I had wanted was simply closure, a way to stop thinking about questions whose answers were beyond my reach." - "Science keeps revealing how much we don't, perhaps can't, know. Yet humans seek closure, which should make religious pluralists of us all." - "Ignorance was a great human breakthrough, perhaps the greatest of all, for until our prehistoric but anatomically modern ancestors could tell the difference between ignorance and knowledge, how could they know they knew anything?

Sign in to read: Just obeying orders? Rethinking obedience and atrocity - opinion - 12 September 2014 - New Scientist
Stanley Milgram "shock experiments" "Not only have recent historical studies led researchers to question Arendt's claims that Eichmann and his ilk simply went along thoughtlessly with the orders of their superiors, but reanalysis of Milgram's work has also led social psychologists to cast serious doubt on the claim we are somehow programmed to obey authority." See sidebar on Philip Zimbardo "prison experiment": "Although Zimbardo presents his findings as evidence of "blind conformity" to role, it is apparent that he gave his guards clear guidance on how he expected them to behave when briefing them for the study." "...we have argued that the behaviour of those guards was not the result of blind conformity, but the result of engaged followership that flowed from identification with Zimbardo's leadership"

We must prepare for superintelligent computers - opinion - 08 July 2014 - New Scientist
based on his book "Superintelligence: Paths, dangers, strategies" - best outline analysis of the singularity that I've seen Distinguishes 3 forms of superintelligence: (1) speed (2) collective (3) quality. Bottom line: "We cannot hope to compete with such machine brains. We can only hope to design them so that their goals coincide with ours. Figuring out how to do that is a formidable problem. It is not clear whether we will succeed in solving that problem before somebody succeeds in building a superintelligence. But the fate of humanity may depend on solving these two problems in the correct order."

42nd St paradox: Cull the best to make things better - physics-math - 16 January 2014 - New Scientist
"According to the emerging science of networks, there are good reasons why some systems perform better in seemingly disadvantageous conditions." Dietrich Braess, late 60s: "while working on ways to find the optimal solution for traffic flow through a network of roads that he made a surprising discovery: adding an extra street to a simple network can actually increase overall travel times" Good road traffic example why Nash Equilibrium isn't optimal: "Suppose five drivers choose the 10-minute journey on the highway. The other five take the shorter route giving them a 5-minute commute. Now the average journey time is 7.5 minutes – the shortest possible average."

The Frustratingly Slow Pace of Making Changes : zenhabits
Give up on the results. Instead focus on the step in front of you. Give up on the fantasy. Instead be curious about what it’s really like when you try it. Don’t be motivated by achieving the ideal. Be motivated by compassion for yourself and helping others. Don’t be caught up in quick results. Savor the slow change. Forget about the happiness of the outcome. Instead find happiness in the learning. Don’t worry about perfect execution. The entire point is to learn about yourself.

Struggle For Smarts? How Eastern And Western Cultures Tackle Learning : Shots - Health News : NPR
"I think that from very early ages we [in America] see struggle as an indicator that you're just not very smart," Stigler says. "It's a sign of low ability — people who are smart don't struggle, they just naturally get it, that's our folk theory. Whereas in Asian cultures they tend to see struggle more as an opportunity." In Eastern cultures, Stigler says, it's just assumed that struggle is a predictable part of the learning process. Everyone is expected to struggle in the process of learning, and so struggling becomes a chance to show that you, the student, have what it takes emotionally to resolve the problem by persisting through that struggle.

Riddled with irregularity - Prospect Magazine Aug 2012
Why are languages so different—and disorderly?

"The Italian team devised a computer model of language evolution in which new words arise through the game played by pairs of “agents”—a speaker and a listener. In this model, the speaker uses words to refer to objects in a scene, and if he or she uses a word that is new to the listener (for a new colour, say), there’s a chance that the listener will figure out what the word refers to and adopt it. Alternatively, the listener might already have a word for that colour, but choose to replace it with the new word anyway. The language of the population evolves from these exchanges."

Human cycles: History as science : Nature News & Comment
"To Peter Turchin, who studies population dynamics at the University of Connecticut in Storrs, the appearance of three peaks of political instability at roughly 50-year intervals is not a coincidence. For the past 15 years, Turchin has been taking the mathematical techniques that once allowed him to track predator–prey cycles in forest ecosystems, and applying them to human history. He has analysed historical records on economic activity, demographic trends and outbursts of violence in the United States, and has come to the conclusion that a new wave of internal strife is already on its way" "In their analysis of long-term social trends, advocates of cliodynamics focus on four main variables: population numbers, social structure, state strength and political instability."

DOJ review of flawed FBI forensics processes lacked transparency - The Washington Post
"A Washington Post review of the department’s actions shows an agency struggling to balance its goal of defending convictions in court with its responsibility to protect the innocent. The Justice Department’s decision to allow prosecutors to decide what to disclose to defendants was criticized at the time and allowed most of the process to remain secret. But by cloaking cases in anonymity, failing to ensure that defendants were notified of troubles with their cases, and neglecting to publicly report problems or recommend solutions, the task force obscured problems from further study.

One group of experts tended to use one analytical tool in many different domains; they preferred keeping their analysis simple and elegant by minimizing “distractions.” These experts zeroed in on only essential information, and they were unusually confident. . .

The other lot used a wide assortment of analytical tools, sought out information from diverse sources, were comfortable with complexity and uncertainty, and were much less sure of themselves—they tended to talk in terms of possibilities and probabilities and were often happy to say “maybe.” . . .
