My Great-Great-Aunt Discovered Francium. And It Killed Her. - NYTimes.com - 0 views

  • There is a common narrative in science of the tragic genius who suffers for a great reward, and the tale of Curie, who died from exposure to radiation as a result of her pioneering work, is one of the most famous. There is a sense of grandeur in the idea that paying heavily is a means of advancing knowledge. But in truth, you can’t control what it is that you find — whether you’ve sacrificed your health for it, or simply years of your time.
  • How quickly an element decayed and how it did so — meaning which of its component parts it shed — became the focus of researchers in radioactivity. Apart from purely scientific insights, there was a hope that radiation could lead to something marvelous. X-rays, a kind of radiation discovered by Wilhelm Roentgen and produced by accelerated electrons, had already been hailed as a major medical breakthrough and, in addition to showing doctors their patients’ insides, were being investigated as a treatment for skin lesions from tuberculosis and lupus. In her 1904 book “Investigations on Radioactive Substances,” Marie Curie wrote that radium had promise, too — diseased skin exposed to it later regrew in a healthy state. Radium’s curious ability to destroy tissue was being turned against cancer, with doctors sewing capsules of radium into the surgical wounds of cancer patients (including Henrietta Lacks, whose cells are used today in research). This enthusiasm for radioactivity was not confined to the doctor’s office. The element was in face creams, tonics, even candy. According to the Encyclopaedia Britannica article that Curie and her daughter wrote on radium in 1926, preliminary experiments suggested that radium could even improve the quality of soil.
  • Perhaps the most tragic demonstration of this involved workers at the United States Radium Corporation factory in Orange, N.J., which in 1917 began hiring young women to paint watch faces with glow-in-the-dark radium paint. The workers were told that the paint was harmless and were encouraged to lick the paintbrushes to make them pointy enough to inscribe small numbers. In the years that followed, the women began to suffer ghoulish physical deterioration. Their jaws melted and ballooned into masses of tumors larger than fists, and cancers riddled their bodies. They developed anemia and necrosis. The sensational court case started — and won — by the dying Radium Girls, as they were called, is a landmark in the history of occupational health. It was settled in June 1928, four months before Marguerite Perey arrived at the Radium Institute to begin a 30-year career of heavy exposure to radiation.

  • We know now that alpha and beta particles emitted in radiation attack DNA and that the mutations they cause can lead to cancer. Ingested radioactive elements can concentrate in the bones, where they continue their decay, in effect poisoning someone for as long as that person lives. By the time Perey made her discovery, she was already heavily contaminated. She spent the last 15 years of her life in treatment for a gruesome bone cancer that spread throughout her body, claiming her eyesight, pieces of her hand and most of the years in which she had planned to study francium. As the disease progressed, she warned her students of the horrible consequences of radiation exposure. Francis, my grandfather, says he recalls hearing that when she walked into labs with radiation counters in her later years, they would go off.
  • Over the years, historians have pondered what drove the Curies to throw caution so thoroughly to the wind. Perhaps it was inconceivable to them that the benefits of their research would not outweigh the risks to themselves and their employees. In a field in which groundbreaking discoveries were being made and the competition might arrive there first, speed was put above other concerns, Rona noted. But you almost get the impression that in the Curie lab, dedication to science was demonstrated by a willingness to poison yourself — as if what made a person’s research meaningful were the sacrifices made in the effort to learn something new.

Margaret Atwood on Our Robotic Future - NYTimes.com - 0 views

  • Many of our proposed futures contain robots. The present also contains robots, but The Future is said to contain a lot more of them. Is that good or bad? We haven’t made up our minds. And while we’re at it, how about a robotic mind that can be made up more easily than a human one?Sci-fi writers have been exploring robots for decades, but they were far from the first to do so. Humankind has been imagining nonbiological but sentient entities that do our bidding ever since we first set stylus to papyrus.
  • To understand Homo sapiens’ primary wish list, go back to mythology. We endowed the gods with the abilities we wished we had ourselves: immortality and eternal youth, flight, resplendent beauty, total power, climate control, ultimate weapons, delicious banquets minus the cooking and washing up — and artificial creatures at our beck and call.
  • Every technology we develop is an extension of one of our own senses or capabilities. It has always been that way. The spear and the arrow extended the arm, the telescope extended the eye, and now the Kissinger kissing device extends the mouth. Every technology we’ve ever made has also altered the way we live. So how different will our lives be if the future we choose is the one with all these robots in it?

Excerpt - 'Love and Math' - NYTimes.com - 0 views

  • What if at school you had to take an “art class” in which you were only taught how to paint a fence? What if you were never shown the paintings of Leonardo da Vinci and Picasso? Would that make you appreciate art? Would you want to learn more about it? I doubt it. You would probably say something like this: “Learning art at school was a waste of my time. If I ever need to have my fence painted, I’ll just hire people to do this for me.” Of course, this sounds ridiculous, but this is how math is taught, and so in the eyes of most of us it becomes the equivalent of watching paint dry. While the paintings of the great masters are readily available, the math of the great masters is locked away.

Executing Them Softly - NYTimes.com - 0 views

  • Since the late 19th century in the United States, critical responses to the spectacle of pain in executions have continued to spur ardent calls for the improvement of killing technology. One of the most prolific legal theorists of capital punishment, Austin Sarat, has concisely referred to this history: “The movement from hanging to electrocution, from electrocution to the gas chamber, from gas to lethal injection, reads like someone’s version of the triumph of progress, with each new technique enthusiastically embraced as the latest and best way to kill without imposing pain.” Recent debates over the administration of midazolam and pentobarbital, and in what dosage, seamlessly integrate themselves into Sarat’s grim progress narrative. The inexhaustible impulse to seek out less painful killing technologies puts a series of questions in sharp relief: What is, and should be, the role of pain in retributive justice? And how has the law come to rationalize the condemned’s experience of pain during an execution? While the Eighth Amendment stipulates the necessity of avoiding “cruel and unusual punishment,” in 1890 the Supreme Court decided this clause could mean that no method of execution should impose “something more than the mere extinguishment of life.” And then, in 1958, the court also determined that the amendment should reflect the “evolving standards of decency that mark the progress of a maturing society.” If we were to consider the “standard of decency” in our society today, we would be pushed to ask: By what moral order have we continued to establish the “extinguishment of life” as something “mere,” and the pain of the condemned as excessive? In other words, how has the pain experienced during an execution become considered cruel and unconstitutional but not the very act of killing itself? We should dial back to older histories of law to tap into pain’s perennially vexed role in retributive theories of justice.

How 17 Equations Changed the World | Brain Pickings - 0 views

  • A good many times I have been presented at gatherings of people who, by the standards of the traditional culture, are thought highly educated and who have with considerable gusto been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and have asked the company how many of them could describe the Second Law of Thermodynamics. The response was cold: it was also negative. Yet I was asking something which is about the scientific equivalent of: ‘Have you ever read a work of Shakespeare’s?’

Stanford psychologist: People from different cultures express sympathy differently - 0 views

  • Stanford psychologist Jeanne Tsai found that Americans tend to focus on the positive in expressions of sympathy while Germans focus on the negative. The research showed that how much people wanted to avoid negative emotion influenced their expressions of sympathy more than how negative they actually felt.

  • Unfortunately, Dr. Kane’s study arrives alongside a troubling new reality. His project was made possible by funding from the National Institute of Mental Health before it implemented a controversial requirement: Since 2014, in order to receive the institute’s support, clinical researchers must explicitly focus on a target such as a biomarker or neural circuit. It is hard to imagine how Dr. Kane’s study (or one like it) would get funding today, since it does not do this. In fact, psychiatry at present has yet to adequately identify any specific biomarkers or circuits for its major illnesses.

BBC - Future - The man who studies the spread of ignorance - 0 views

  • How do people or companies with vested interests spread ignorance and obfuscate knowledge?
  • In one of the paper’s most revealing sections, it looks at how to market cigarettes to the mass public: “Doubt is our product since it is the best means of competing with the ‘body of fact’ that exists in the mind of the general public.
  • It comes from agnosis, the neoclassical Greek word for ignorance or ‘not knowing’, and ontology, the branch of metaphysics which deals with the nature of being. Agnotology is the study of wilful acts to spread confusion and deceit, usually to sell a product or win favour.

How '-Phobic' Became a Weapon in the Identity Wars - The New York Times - 1 views

  • The ‘‘-phobic’’ suffix has emerged as the activist’s most trusted term of art for pinning prejudice on an opponent. There’s ‘‘xenophobic,’’ ‘‘homophobic,’’ ‘‘Islamophobic,’’ ‘‘transphobic,’’ ‘‘fatphobic’’ and ‘‘whorephobic’’: Any blowhard who spews bigotry against a marginalized group — or any journalist who pens an article perceived as insufficiently sensitive — risks being called out for an irrational anxiety over one Other or another. When did this particular diagnosis become such a powerful weapon in the identity wars?
  • ‘‘Homophobia’’ was a hit. Weinberg had intuited that culture wars are waged not just in hearts and minds, but also in conversation.

What Economics Can (and Can't) Do - The New York Times - 1 views

  • It would seem that in situations like the current Greek crisis, we should be able to rely on economics to tell us which policies are most likely to work. But does the discipline have sufficient predictive power to play an important role in our debates about public policy?
  • The problems that we want economists to help us solve are more like predicting how leaves will fall on a windy day than predicting how objects will fall in a vacuum. Economic phenomena are affected by a very large number of causal factors of many different kinds.

Teens do better in science when they know Einstein and Curie also struggled - Quartz - 0 views

  • Students who learned that great scientists struggled, both personally and intellectually, outperformed those who learned only of the scientists’ great achievements, new research shows.
  • “In our culture we always say you don’t want to intimidate kids, you don’t want to tell them how hard the work is,” she noted. But the experiment showed the opposite strategy works better: Showing how great scientists had to muddle through lots of tough stuff made the subject matter real and allowed students to connect with them as people.
  • Some people learn better when the content has meaning to them. For those students, science comes to life more through personal stories than through the actual scientific content.

  • And kids who learn that intellect is a malleable thing, something to be built rather than inherited, take more academic risks and perform better. The study adds to the growing body of research in favor of teaching this “growth mindset” or the belief that the brain, like other muscles in the body, can be strengthened and improved through struggle and hard work.

Imitation is what makes us human and creative - Kat McGowan - Aeon - 3 views

  • Throughout human history, innovation – including the technological progress we cherish – has been fuelled and sustained by imitation. Copying is the mighty force that has allowed the human race to move from stone knives to remote-guided drones, from digging sticks to crops that manufacture their own pesticides.

  • Lots of copying means that many minds get their chance at the problem; imitation ‘makes the contents of brains available to everyone’, writes the developmental psychologist Michael Tomasello in the Cultural Origins of Human Cognition (1999). Tomasello, who is co-director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, calls the combination of imitation and innovation the ‘cultural ratchet’. It is like a mechanical ratchet that permits motion in only one direction – such as winding a watch, or walking through a turnstile. Good ideas push the ratchet forward one notch. Faithful imitation keeps the ratchet from slipping backward, protecting ideas from being forgotten or lost and keeping knowledge alive for the next round of improvement.

  • In the 1930s, a pair of psychologists raised an infant chimp alongside their own baby in an attempt to understand both species better. The chimp raised in this family (and others in other such experiments later in the century) never behaved much like a human. The human child, on the other hand, soon began knuckle-walking, biting, grunting and hooting – just like his new sibling.
