Here ‘lies’ Aristotle, archaeologist declares — and this is why we should care

Amy Ellis Nutt writes: For starters, he is the father of Western science and Western philosophy. He invented formal logic and the scientific method and wrote the first books about biology, physics, astronomy and psychology. Freedom and democracy, justice and equality, the importance of a middle class and the dangers of credit — they’re just a sampling of Aristotle’s political and economic principles. And, yes, Christianity, Islam and our Founding Fathers also owe him a lot.

Nearly 2-1/2 millennia after Aristotle’s birth, we now know where his ashes most likely were laid to rest: in the city of his birth, Stagira, on a small, picturesque peninsula in northern Greece.

“We have no [concrete] evidence, but very strong indications reaching almost to certainty,” archaeologist Kostas Sismanidis said through a translator at this week’s World Congress celebrating “Aristotle 2400 Years.” [Continue reading…]

The void of the float tank stops time, strips ego and unleashes the mind

structure9

M M Owen writes: The floatation tank was invented in 1954. Amid debates over whether consciousness was a purely reactive phenomenon or generated by resources of its own making in the mind, the neuroscientist John Lilly arrived at a novel way to examine the problem: isola te the mind from all sources of external stimulation, and see how it behaved. Serendipitously, Lilly’s place of work, the National Institute of Mental Health in Bethesda, Maryland, possessed a sealed, soundproof tank, built during the Second World War to facilitate Navy experiments on the metabolisms of deep-sea divers. The first floatation tank was born. It resembled a large upright coffin, in which the floater was suspended in water, head engulfed in a rubber breathing mask. Despite this grim setup, during his floats Lilly perceived that the mind was far from merely reactive, and that ‘many, many states of consciousness’ emerged from total isolation. He was hooked.

Lilly was the sort of scientist it’s hard to imagine rising to prominence today. Alongside inventing the first floatation tank, he was an evangelist of psychedelics fascinated by human-dolphin communication and convinced that a council of invisible cosmic entities governed reality. Despite a mixed reputation among his scientific peers, Lilly’s almost single-handed promotion of floating in the 1960s caused it to catch on. In 1972, the computer programmer Glenn Perry attended one of Lilly’s floating workshops, and was so taken with the tank experience that, over the following year, he designed the first inexpensive tanks for home use. To this day, his so-called ‘Samadhi’ tanks (after the ultimate stage in meditation) remain among the most popular, with retail prices starting at around $11,000.

Cultural notables such as the polymath Gregory Bateson and the self-help guru Werner Erhard visited Lilly’s Malibu home and tried out his tank. Word spread. In 1979, Perry opened the first commercial float centre in Beverly Hills.[Continue reading…]

The unexpected sophistication of Neanderthals

Discover reports: Circular structures discovered in a French cave continue to build the case that Neanderthals were more intelligent than we give them credit for.

Deep inside the Bruniquel Cave, researchers discovered two rings of stalactites and stalagmites that appeared to have been deliberately stacked and arranged to form a structure. The site also contained charred animal bones, which may have served as torches to illuminate the dark depths of the cave or keep bears at bay. The thing is, a new dating analysis suggests these structures were built more than 170,000 years ago, long before Homo sapiens arrived in the area. That means Neanderthals were the likely architects, and we didn’t expect them to be such adept builders and cave explorers.

The structures in Bruniquel were first discovered in 1990 and dated at the time to roughly 50,000 years ago based on carbon dating techniques. However, in 2013, Sophie Verheyden of the Royal Belgian Institute of Natural Sciences conducted a new study, drilling into the stalactites and stalagmites to measure differences between layers of rock that accumulated before and after they were felled. Her analysis, published Wednesday in Nature, revealed an astounding age of roughly 176,500 years, more than three times the previous estimate. By contrast, the oldest known human cave art is only around 42,000 years old. [Continue reading…]

What the songs of wolves reveal about language

Holly Root-Gutteridge writes: Dialects, or regional differences in the form and use of vocalisations, have been observed in birds, bats, chimpanzees and now an increasingly long list of other species. This has been most beautifully heard in whales, where the songs of humpbacks are transmitted across hundreds of miles, telling a listener which part of the ocean the whale lives in, and tracing its family group by the influences on song formations. The bioacousticians Katharine Payne and Roger Payne first listened to the whales on underwater microphone recordings in the 1960s, and used musical notation to explore the changes that occurred in each male’s song, year on year. Whalesong, heard by humans as long ago as Aristotle, became the subject of intense study and public interest. Their research showed that there were geographic differences in humpback whale songs and that we could tell apart populations just by using those songs, which change throughout their lives. So the whales were controlling their singing and subject to cultural influences. The Paynes had found dialects in whale song. Would we find the same for canids?

Despite their cultural popularity, wolf howls haven’t been the subject of focussed research until recently. Now, following the lead of marine biologists and ornithologists, and with improved sound recording equipment and analysis programs, researchers can study them in depth. The first step in understanding what animals are saying to one another is to figure out what aspects of the voice are functional and what parts are formed by the structure of the throat and mouth, or what is the piano and what is the tune. Studies since the 1960s have shown that the howls that have haunted our dreams for centuries can tell us a lot about the particular wolf vocalising. Like humans, each wolf has its own voice. Each pack also shares howl similarities, making different families sound distinct from each other (wolves respond more favourably to familiar howls). This much we knew. What we didn’t know was whether the differences seen between packs were true of subspecies or of species, and if an Indian wolf howl would be distinct from a Canadian one.

More questions follow. If howls from different subspecies are different, do the howls convey the same message? Is there a shared culture of howl-meanings, where an aggressive howl from a European wolf means the same thing as an aggressive howl of a Himalayan? And can a coyote differentiate between a red wolf howling with aggressive intent and one advertising the desire to mate? Even without grammar or syntax, howls can convey intent, and if the shape of the howl changes enough while the intent remains constant, the foundations of distinctive culture can begin to appear.

How did Earth warm enough to support life?

Space.com reports: Life on Earth may owe its existence to incredibly powerful storms that erupted on the sun long ago, a new study suggests.

Potent and frequent solar eruptions could have warmed the planet enough for life to take root, and also provided the vital energy needed to transform simple molecules into the complex building blocks of life, such as DNA, researchers said.

The first organisms evolved on Earth about 4 billion years ago. This fact has long puzzled scientists, because in those days, the sun was only about 70 percent as bright as it is today.

“That means Earth should have been an icy ball,” study lead author Vladimir Airapetian, a solar scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said in a statement. “Instead, geological evidence says it was a warm globe with liquid water. We call this the Faint Young Sun Paradox.” [Continue reading…]

Rules of the underworld

Katherine Hirschfeld writes: In March 2013, a drug cartel staged a grisly tableau near a central plaza in Uruapan, Mexico. Seven dead and mutilated bodies were left sitting upright in plastic chairs. Two had crudely lettered signs pinned to their chests with ice picks that read, “Warning, this is going to happen to all muggers, pickpockets, thieves of cars, homes, and walkers — as well as kidnappers, rapists, and extortionists.” Photos found their way to CNN and other media outlets in the United States and Europe. (You may view them here if you are brave.)

Those who inhabit the upper world — law-abiding citizens who enjoy the rights and protections of government — instinctively turn away from such images of horrific violence. Not only are the photos disturbing to look at, they don’t make sense. Why would a drug cartel go to such lengths to issue a proclamation against thievery? Drug cartels are not law-abiding organizations, so why arrange a display of dead bodies with ice picks and cardboard signs in order to declare rules?

The scene at Uruapan contains a message from the underworld — the subterranean organized crime groups that control much of the world’s traffic in illicit commodities. Criminal organizations often communicate through the bodies of the dead, and we should not look away just yet, because their message contains a warning for all of us.

What the bodies in Uruapan tell us is that underworld groups are law-and-order organizations, but their laws and their order are not the same as those of the upper world. We know this because the intrepid journalists, human rights activists, and forensic anthropologists who have crossed over to explore specific examples of the global underworld have brought back stories that reveal common themes. Criminal groups may be culturally or geographically distinct, but they operate with similar rules.

The primary rule of the underworld is that the cartel (or the mafia or the warlord) makes the rules, and disobedience is a capital crime. Public displays of death convey the cartel’s power to impose the kind of lethal punishment typically reserved for the state. The public setting in Uruapan symbolizes that the Mexican government no longer has jurisdiction over matters of criminal justice in this municipality. Through these practices, the cartel reanimates the dead and compels them to speak to the living one last time: “Obey, or you will end up like us.” [Continue reading…]

How Facebooks taps into our lack of imagination

Frank Bruni writes: Those who’ve been raising alarms about Facebook are right: Almost every minute that we spend on our smartphones and tablets and laptops, thumbing through favorite websites and scrolling through personalized feeds, we’re pointed toward foregone conclusions. We’re pressured to conform.

But unseen puppet masters on Mark Zuckerberg’s payroll aren’t to blame. We’re the real culprits. When it comes to elevating one perspective above all others and herding people into culturally and ideologically inflexible tribes, nothing that Facebook does to us comes close to what we do to ourselves.

I’m talking about how we use social media in particular and the Internet in general — and how we let them use us. They’re not so much agents as accomplices, new tools for ancient impulses, part of “a long sequence of technological innovations that enable us to do what we want,” noted the social psychologist Jonathan Haidt, who wrote the 2012 best seller “The Righteous Mind,” when we spoke last week.

“And one of the things we want is to spend more time with people who think like us and less with people who are different,” Haidt added. “The Facebook effect isn’t trivial. But it’s catalyzing or amplifying a tendency that was already there.”

By “the Facebook effect” he didn’t mean the possibility, discussed extensively over recent weeks, that Facebook manipulates its menu of “trending” news to emphasize liberal views and sources. That menu is just one facet of Facebook.

More prevalent for many users are the posts we see from friends and from other people and groups we follow on the network, and this information is utterly contingent on choices we ourselves make. If we seek out, “like” and comment on angry missives from Bernie Sanders supporters, we’ll be confronted with more angry missives from more Sanders supporters. If we banish such outbursts, those dispatches disappear.

That’s the crucial dynamic, algorithm or whatever you want to call it. That’s the trap and curse of our lives online.

The Internet isn’t rigged to give us right or left, conservative or liberal — at least not until we rig it that way. It’s designed to give us more of the same, whatever that same is: one sustained note from the vast and varied music that it holds, one redundant fragrance from a garden of infinite possibility.

The range of the mind’s eye is restricted by the skill of the hand

structure12

Jonathan Waldman writes: Sometime in 1882, a skinny, dark-haired, 11-year-old boy named Harry Brearley entered a steelworks for the first time. A shy kid — he was scared of the dark, and a picky eater — he was also curious, and the industrial revolution in Sheffield, England, offered much in the way of amusements. He enjoyed wandering around town — he later called himself a Sheffield Street Arab — watching road builders, bricklayers, painters, coal deliverers, butchers, and grinders. He was drawn especially to workshops; if he couldn’t see in a shop window, he would knock on the door and offer to run an errand for the privilege of watching whatever work was going on inside. Factories were even more appealing, and he had learned to gain access by delivering, or pretending to deliver, lunch or dinner to an employee. Once inside, he must have reveled, for not until the day’s end did he emerge, all grimy and gray but for his blue eyes. Inside the steelworks, the action compelled him so much that he spent hours sitting inconspicuously on great piles of coal, breathing through his mouth, watching brawny men shoveling fuel into furnaces, hammering white-hot ingots of iron.

There was one operation in particular that young Harry liked: a toughness test performed by the blacksmith. After melting and pouring a molten mixture from a crucible, the blacksmith would cast a bar or two of that alloy, and after it cooled, he would cut notches in the ends of those bars. Then he’d put the bars in a vise, and hammer away at them.

The effort required to break the metal bars, as interpreted through the blacksmith’s muscles, could vary by an order of magnitude, but the result of the test was expressed qualitatively. The metal was pronounced on the spot either rotten or darned good stuff. The latter was simply called D.G.S. The aim of the men at that steelworks, and every other, was to produce D.G.S., and Harry took that to heart.

In this way, young Harry became familiar with steelmaking long before he formally taught himself as much as there was to know about the practice. It was the beginning of a life devoted to steel, without the distractions of hobbies, vacations, or church. It was the origin of a career in which Brearley wrote eight books on metals, five of which contain the word steel in the title; in which he could argue about steelmaking — but not politics — all night; and in which the love and devotion he bestowed upon inanimate metals exceeded that which he bestowed upon his parents or wife or son. Steel was Harry’s true love. It would lead, eventually, to the discovery of stainless steel.

Harry Brearley was born on Feb. 18, 1871, and grew up poor, in a small, cramped house on Marcus Street, in Ramsden’s Yard, on a hill in Sheffield. The city was the world capital of steelmaking; by 1850 Sheffield steelmakers produced half of all the steel in Europe, and 90 percent of the steel in England. By 1860, no fewer than 178 edge tool and saw makers were registered in Sheffield. In the first half of the 19th century, as Sheffield rose to prominence, the population of the city grew fivefold, and its filth grew proportionally. A saying at the time, that “where there’s muck there’s money,” legitimized the grime, reek, and dust of industrial Sheffield, but Harry recognized later that it was a misfortune to be from there, for nobody had much ambition.

There’s no such thing as free will

structure3bw

Stephen Cave writes: For centuries, philosophers and theologians have almost unanimously held that civilization as we know it depends on a widespread belief in free will — and that losing this belief could be calamitous. Our codes of ethics, for example, assume that we can freely choose between right and wrong. In the Christian tradition, this is known as “moral liberty” — the capacity to discern and pursue the good, instead of merely being compelled by appetites and desires. The great Enlightenment philosopher Immanuel Kant reaffirmed this link between freedom and goodness. If we are not free to choose, he argued, then it would make no sense to say we ought to choose the path of righteousness.

Today, the assumption of free will runs through every aspect of American politics, from welfare provision to criminal law. It permeates the popular culture and underpins the American dream — the belief that anyone can make something of themselves no matter what their start in life. As Barack Obama wrote in The Audacity of Hope, American “values are rooted in a basic optimism about life and a faith in free will.”

So what happens if this faith erodes?

The sciences have grown steadily bolder in their claim that all human behavior can be explained through the clockwork laws of cause and effect. This shift in perception is the continuation of an intellectual revolution that began about 150 years ago, when Charles Darwin first published On the Origin of Species. Shortly after Darwin put forth his theory of evolution, his cousin Sir Francis Galton began to draw out the implications: If we have evolved, then mental faculties like intelligence must be hereditary. But we use those faculties — which some people have to a greater degree than others — to make decisions. So our ability to choose our fate is not free, but depends on our biological inheritance.

Galton launched a debate that raged throughout the 20th century over nature versus nurture. Are our actions the unfolding effect of our genetics? Or the outcome of what has been imprinted on us by the environment? Impressive evidence accumulated for the importance of each factor. Whether scientists supported one, the other, or a mix of both, they increasingly assumed that our deeds must be determined by something. [Continue reading…]

The ex-anarchist construction worker who became a world-renowned scientist

lichen7

Daniel Gumbiner writes: “See these lichens here? I don’t know how you see them but, to me, I see them as a surrealist.”

I am sitting in the UC Riverside herbarium, speaking to Kerry Knudsen, Southern California’s only professional lichenologist. We are looking at his collection of lichens, which consists of over 16,000 individual specimens, all of them neatly organized in large green file cabinets. Knudsen has published over 200 peer-reviewed scientific papers on lichens, and discovered more than 60 species that are new to science. It is an extraordinary output, for any scientist, but Knudsen has achieved it in only fifteen years. Science is his second career. For more than two decades he worked in construction. Before that, he was a teenage runaway living in an anarchist commune in Chicago.

“He’s amazing,” said Shirley Tucker, a retired professor of botany at LSU. “He came out of nowhere and became an expert in the most difficult genera.”

A lichen is a fungus in a symbiotic relationship with an algae or a cyanobacteria. The fungus essentially farms the algae or cyanobacteria, who are able to harvest energy from the sun through photosynthesis. In return, the fungus provides the algae or cyanobacteria with protection, but the relationship is a little one-sided.

“The algae is trapped,” Knudsen explained. “It has a lot of tubes going into it. It’s controlled by chemical signals … The first time I saw it under the microscope, I wanted to join the Algae Liberation Front. I mean, it looked bad.”

Scientists believe that lichen evolved over 500 million years ago, about the same time as fish. Although lichen make up 8 percent of the world’s biomass, they are rarely considered by the amateur naturalist, and therefore have very few common names. [Continue reading…]
