6 Scientific Reasons You Should Be Reading More | Mental Floss - 0 views

  • to assess the relationship between cognitive skills, vocabulary, factual knowledge, and exposure to certain fiction and nonfiction authors
  • those who read literary fiction performed better on tasks like predicting how characters would act and identifying the emotion encoded in facial expressions. These speak to the ability to understand others' mental states, which scientists call Theory of Mind.
  • If we engage with characters who are nuanced, unpredictable, and difficult to understand, then I think we're more likely to approach people in the real world with an interest and humility necessary for dealing with complex individuals

  • When we read fiction, we practice keeping our minds open because we can afford uncertainty
  • 100 people were assigned to read a fictional story or a nonfiction essay. The participants then completed questionnaires intended to assess their level of cognitive closure, which is the need to reach a conclusion quickly and avoid ambiguity in the decision-making process. The fiction readers emerged as more flexible and creative than the essay readers—and the effect was strongest for people who read on a regular basis.
  • They saw themselves differently after reading about others' fictional experience.
  • As you identify with another person, a protagonist in the story, you enter into a piece of life that you wouldn't otherwise have known. You have emotions or circumstances that you wouldn't have otherwise understood

Humans Are the World's Best Pattern-Recognition Machines, But for How Long? - Big Think - 0 views

  • Not only are machines rapidly catching up to — and exceeding — humans in terms of raw computing power, they are also starting to do things that we used to consider inherently human
  • Quite simply, humans are amazing pattern-recognition machines. They have the ability to recognize many different types of patterns - and then transform these "recursive probabalistic fractals" into concrete, actionable steps.
  • Intelligence, then, is really just a matter of being able to store more patterns than anyone else
  • ...8 more annotations...
  • Artificial intelligence pioneer Ray Kurzweil was among the first to recognize how the link between pattern recognition and human intelligence could be used to build the next generation of artificially intelligent machines.
  • where human "expertise" has always trumped machine "expertise."
  • It turns out patterns matter, and they matter a lot.
  • The more you think about it, the more you can see patterns all around you. Getting to work on time in the morning is the result of recognizing patterns in your daily commute
  • it's really just a matter of recognizing the right patterns faster than anyone else, and machines just have so much processing power these days it's easy to see them becoming the future doctors and lawyers of the world.
  • The future of intelligence is in making our patterns better, our heuristics stronger.
  • One thing is clear – being able to recognize patterns is what gave humans their evolutionary edge over animals.
  • How we refine, shape and improve our pattern recognition is the key to how much longer we'll have the evolutionary edge over machines.

Inherited Learning? It Happens, but How Is Uncertain | Quanta Magazine - 0 views

  • Most recently, some researchers have found evidence that even some learned behaviors and physiological responses can be epigenetically inherited.
  • But in the 1950s, the botanist Royal Alexander Brink discovered that, under different environmental conditions, maize plants with identical genomes expressed different-colored kernels, and these colors were heritable. It was some of the first evidence for epigenetic inheritance. Since then, more examples of inheritance without a clear genetic basis have come to light, as have a variety of possible mechanisms for epigenetic inheritance.
  • C. elegans worms infected with viruses would defend themselves by generating small RNAs that targeted and neutralized the viruses. Moreover, the subsequent offspring of the roundworms also made these small protective RNAs, even though they had never been exposed to the viruses.
  • ...3 more annotations...
  • He hypothesizes that the process involves one or more molecules released by the nervous system — perhaps small RNAs, perhaps something secreted like a hormone. But somehow those germ cells then influence the behavior of the next generation and seem to circumvent the normal need for rde-4 in the production of the small RNAs for chemotaxis in the progeny.
  • “I believe that today, there is not a single solid paper showing that only small RNAs are involved in epigenetic inheritance,” said Isabelle Mansuy, a neuroepigenetics researcher at the Swiss Federal Institute of Technology Zurich and the University of Zurich who studies the inheritance of trauma in humans and mice. In the mouse model she works with, she knows that small RNAs are not sufficient because if she injects small RNAs alone into fertilized mouse eggs, the resulting animals do not show the RNA-associated trait.
  • “If we can ingest a chemical from our environment that changes the epigenomes of the egg or sperm, why couldn’t our brain make a similar molecule that does the same thing?”

Opinion | Do heuristics help us make good decisions in uncertain times? - 0 views

  • Do heuristics, the shortcuts that the brain takes, support efficient decision making or does it impede efficient decision making?
  • Humans have neither unlimited resources nor unlimited time to take decisions. So, the brain has always developed smart heuristics, shortcuts to take efficient decisions.
  • One other key thought put forward by Gigerenzer is that there is a big difference between risk and uncertainty. We are dealing with risk when you know all the alternatives, outcomes and their probabilities. We are dealing with uncertainty when you don’t know all the alternatives, outcomes or their probabilities.
  • ...1 more annotation...
  • It has been found that if doctors are trained how to translate conditional probabilities into natural frequencies, the ability of the doctors to communicate the risk to their patients goes up dramatically. Just imagine the huge difference this can make to customer satisfaction in the healthcare business.

Coronavirus pandemic: Congress response lets down workers, US economy - Business Insider - 0 views

  • The US share of global GDP is nearly 15%. If our economy can't stabilize and then recover from the coronavirus pandemic, it will be harder for the world to do so
  • it's imperative that Congress write fair, generous legislation to get us through the economic shutdown required to fight the virus
  • But that isn't what's happening. Republicans accuse Democrats of not moving fast enough. Democrats accuse Republicans of short-changing American workers and favoring big corporations.
  • ...9 more annotations...
  • Under-funding this stimulus will drag the global economy down. And any appearance that corporations are getting a more fair deal than individuals will make people not want to comply. A lack of compliance will drag on the crisis.
  • When it falls into ruin, the entire global economy drags. We saw that happen during the financial crisis of 2008.
    • delgadool
       
      Example of comparable situation
  • Congress could under-fund the US coronavirus stimulus package. If they do, they put not only the economy but the effort to fight the virus at risk.
  • this weekend the Senate was unable to pass aid legislation
  • Democrats also rejected the bill over a lack of labor protections that would only mandate corporations keep employees "to the extent possible." They want more limits on executive compensation and share buybacks, and they want more money for healthcare workers. They accuse Republicans of being cheap, and writing a deal that favors corporations over average Americans.
  • The only proposal that comes close to being generous enough for individuals comes from Democratic Rep. Rashida Tlaib. It would give a prepaid card with $2,000 to every American. That card would then be recharged with $1,000 monthly until one year after the end of the coronavirus crisis. This is the kind of plan that will make Americans believe the government has their back, not just the backs of big corporations.
  • The distrust that is bred by corruption will make it much harder to fight this virus, potentially dragging out the crisis. The vast majority of Americans already think that our lack of trust in each other and our government makes it hard to solve problems, according to Pew Research. If Americans feel like this whole aid package is a handout to big corporations — which they also distrust — they may stop listening to authorities.
  • Goldman Sachs estimates that the recession brought on by fighting off coronavirus will trough in April, knocking 10% off US GDP. Over time, bank analysts wrote last week, the economy should begin to grow again incrementally. How fast depends on how well Americans comply with government social-distancing mandates. Americans have to want to comply.
  • Small and midsize companies make up 83% of the US economy, and thousands of workers are already out of a job across the country. Means-testing initial payments to individuals — that is, restricting who gets the checks based on income — is a waste of time.

'Fresh Off the Boat' and the Asian American Entertainment Boom | Hollywood Reporter - 0 views

  • Even as the ABC series slipped in quality, it was instrumental in helping launch a boom in big- and small-screen Asian American representation.
  • Without Fresh Off the Boat, the current Asian American boom in Hollywood wouldn't — couldn't — look like it does today. When the ABC series debuted as a midseason replacement in February 2015, it was the first Asian American family sitcom since the cancellation of Margaret Cho's All-American Girl after one season two decades prior.
  • I wrote my personal eulogy for the sitcom back in 2018, shortly after the Season 5 premiere, and shortly before I regretfully quit watching.
  • ...5 more annotations...
  • But around the fourth season, Jessica became the show's petulant brat needing growing up — a mother of three school-age children who regularly taught her life lessons.
  • Fresh Off the Boat likely hit its artistic peak in the two-part Season 3 finale, when the Huangs briefly move into a mansion they can barely afford on the rich part of town, where they have no friends and can barely keep the lights on.
  • Today's Asian American boom likely would have happened at one juncture or another, but it is genuinely remarkable how many Asian American projects — and how many different kinds of Asian American representation — have come out of Fresh Off the Boat. To briefly play Sliding Doors, if ABC had never taken a chance on Fresh Off the Boat, it's harder to imagine Crazy Rich Asians being greenlit with nary a recognizable star, especially one like Wu, who had garnered much good will in the show's early seasons by advocating for Asian American issues off screen as well.
  • For a series based on a chef's autobiography and regularly set at a restaurant, food has played a relatively minor role on Fresh Off the Boat.
  • It's entirely possible that plenty of Asian American progress would've happened in the Sliding Doors version of our universe where Fresh Off the Boat never made it onto the air.

Bose is the latest tech company to expand into healthcare - 0 views

  • We form beliefs in a haphazard way, believing all sorts of things based just on what we hear out in the world but haven’t researched for ourselves.
  • It turns out, though, that we actually form abstract beliefs this way: We hear something; We believe it to be true; Only sometimes, later, if we have the time or the inclination, we think about it and vet it, determining whether it is, in fact, true or false
  • “People are credulous creatures who find it very easy to believe and very difficult to doubt. In fact, believing is so easy, and perhaps so inevitable, that it may be more like involuntary comprehension than it is like rational assessment.”

  • Under any sort of pressure, they presumed all the statements were true, regardless of their labeling.
  • How we form beliefs was shaped by the evolutionary push toward efficiency rather than accuracy.
  • Before language, our ancestors could form new beliefs only through what they directly experienced of the physical world around them. For perceptual beliefs from direct sensory experience, it’s reasonable to presume our senses aren’t lying. Seeing is, after all, believing. In fact, questioning what you see or hear can get you eaten. For our evolutionary ancestors, it was better to be safe than sorry, especially when considering whether to believe that rustling in the grass is a lion.As a result, we didn’t develop a high degree of skepticism when our beliefs were about things we directly experienced, especially when our lives were at stake.
  • As complex language evolved, we gained the ability to form beliefs about things we hadn’t actually experienced for ourselves–and tended to believe them just as strongly.
  • The bigger risk is in failing to update our beliefs when new information arises
  • we still form beliefs without vetting most of them, and maintain them even after receiving clear, corrective information.
  • The next time you argue with someone about something you believe to be true, step back and ask yourself how you came to this conclusion.

Einstein's Theory of Relativity, Explained in a Pioneering 1923 Silent Film - Brain Pickings - 0 views

  • “This is a participatory universe,” physicist John Archibald Wheeler, who popularized the term black hole, wrote in his influential theory known as It from Bit, asserting that “physics gives rise to observer-participancy; observer-participancy gives rise to information; and information gives rise to physics” — an assertion he could not have made without Einstein’s theory of relativity and its groundbreaking insight into how the laws of physics appear to different observers with different frames of reference.

Sensory perception | Science Features | Naked Scientists - 0 views

  • Deciphering how the brain processes sight and hearing could have implications for how we understand and treat conditions such as dyslexia, autism and schizophrenia.
  • schizophrenia
  • Through a project called SENSOCOM, she is exploring how sensory perception affects communication, focusing on the brain’s deep subcortical structures.By doing this, she and her team are exploring a part of the brain traditionally excluded by research trying to understand communication impairments found in autism spectrum disorder and dyslexia, conditions which affect around 53 million people in Europe.
  • ...5 more annotations...
  • To do this they have been focusing on the sensory pathways linked to these deep structures. She and her group discovered that adults with dyslexia have weaker pathway connections between a visual subcortical structure (the left visual thalamus) with an area of the cortex called V5/MT, which is critical for the perception of visual motion. In the auditory mode, there was a similar finding. The team discovered weaker connections between the left auditory thalamus and a cortex structure linked to auditory motion, which is important for speech perception. These connections could therefore be important for reading and for predicting reading skill, according to Dr von Kriegstein.
  • So how might this translate into helping people with dyslexia? This is basic science, says Prof. von Kriegstein, so first it’s crucial to understand the mechanisms behind communications disorders before developing therapy training tools, although she is optimistic these could lie within reach.
  • The way the brain encodes information and in turn directs perception of that sensory experience is a highly variable process.
  • The sensory overload or distorted and heightened perceptions described by schizophrenia patients, for instance, could relate to these deficits. Sensory dysfunction has also been linked to delusions and hallucinations as well as difficulties with attention and reading the emotions or tone of others – all of which can affect social interaction.
  • According to Dr Fellin, decreased connectivity between nerve cells (neurons) appears to play an important role in the progression of schizophrenia. So far, Dr Fellin and his group have identified which specific neurons influence sensory responses in mouse studies, but not yet in animal models of schizophrenia, with similar investigations in glial cells  - the supporting cells of the nervous system.

How coronavirus hypocrisy is tarnishing Boris Johnson's government (opinion) - CNN - 0 views

  • Johnson has proved staunch in his defense of his close ally since the latter was accused of breaking the UK's strict lockdown by driving 260 miles with his wife, who he admits was displaying some symptoms of coronavirus, and young son to be near his extended family.
  • In quarantine-fatigued Britain, however, where many have agonized over the command to stay away from frightened, sick and dying relatives, the Prime Minister's words have not gone down well. Highly unusually, several of his own Conservative MPs are now calling for Cummings to be sacked, and even the government-friendly Daily Mail asked: "What Planet Are They On?" of his decision to stand by his man.
  • In one of the more moving responses, Helen Goodman, until December the Labour Party MP for Durham, the northern town Cummings visited to stay in a property belonging to his parents, said she was "appalled" by his behavior, given her own father had died alone from Covid-19 in a local care home after she obeyed the rules and did not visit.
  • ...10 more annotations...
  • Saying he had no regrets, he added: "I believe in all circumstances I behaved reasonably and legally. The legal rules do not inevitably cover all circumstances - including those I found myself in." Also on Monday, Johnson expressed "regret" for the "confusion, anger and pain" experienced by the British people as a result of the controversy; when pressed on whether he believes Cummings' decision has compromised the government's coronavirus message, Johnson doubled down on his support for Cummings, asserting, "I do not believe that anybody at Number 10 has done anything to undermine our message."
  • "The regulations made clear, I believe, that risks to the health of a small child were an exceptional situation."
  • To talk of the British sense of fair play is almost a cliché. But there is certainly a particular sensitivity among Britons to suggestions of hypocrisy which have thus far thwarted Cummings' attempts to brush off criticism of his excursion, and which contrast with, say, the relative lack of fuss in the US over the revelation that Ivanka Trump, President Donald Trump's daughter, traveled from Washington DC to New Jersey to celebrate Passover last month.
  • A controversial figure who relishes his role as an outsider, he also has a common touch when it comes to distilling a message with a brilliance complemented by Johnson's own flair for capturing the national mood. So while it was Johnson, then-Mayor of London, who in 2016 sensed an appetite for leaving the EU which his more senior colleagues missed, it was Cummings, head of the Vote Leave Campaign, who boiled it down to the simple and devastatingly effective slogan of "Take Back Control."
  • For a man known for his gregarious nature, the British Prime Minister has few close political friends; his inexperienced cabinet was appointed as much for their loyalty and support for his key policy of leading the UK out of the European Union as any long-term affinity with Johnson.
  • At the start of the lockdown, Dr. Catherine Calderwood, Scotland's Chief Medical Officer, fell on her sword after admitting two overnight visits at her seaside holiday cottage, having fronted the campaign urging Scots to stay home. Though Calderwood apologized for her actions and initially said she planned to stay on in her post, she later released a statement that she had quit and acknowledging that the "justifiable focus" on her actions could pose a distraction to the response to the pandemic.
  • As senior adviser since summer 2019 when Johnson became Prime Minister, the notoriously prickly Cummings has rubbed many Downing Street denizens the wrong way. But when coronavirus hit, it was he who crafted the message, "Stay Home, Protect the NHS, Save Lives," which has come to define Britain's battle against the virus and the protective shield the country threw around its beloved health service.
  • The hitherto wildly popular Johnson's favorability ratings have begun to slip while a recent poll by YouGov found 49% disapproved of the Prime Minister's path out of lockdown compared to 36% who supported it.
  • The former Chief Constable of Durham Police, Mike Barton, has warned that Cummings' behavior, and the Prime Minister's defense of it, will make attempts to enforce the lockdown impossible, potentially endangering the slow but steady progress the UK has made in reducing the spread of the virus.
  • The consequences could be even more serious if a mass loss of faith in both the Johnson government and his lockdown results in the public breaking the rules just at the moment the Prime Minister is urging them to stand firm.

Elijah Cummings knew how to walk the tightrope of racial politics - CNNPolitics - 0 views

  • Perhaps no one so visibly crystallized the dissonance between black Americans and their country than Democratic Rep. Elijah Cummings of Maryland, who died last Thursday and whose funeral service, at which the Clintons and former President Barack Obama will deliver remarks, is on Friday.
  • "In the Congress, Elijah was considered a north star," House Speaker Nancy Pelosi recalled. "He was a leader of towering character and integrity. He lived the American dream." Pelosi also underscored that Cummings "spoke with unsurpassed clarity and moral integrity" -- that "everyone wanted to hear what Elijah had to say."
  • "Every time we spoke of selecting an individual who can rise to the occasion to be in debate with him, we would look for somebody who was strong, and every time someone was selected, they'd come back to be a very best friend of Elijah Cummings," House GOP leader Kevin McCarthy of California said.
  • ...4 more annotations...
  • And yet, those accounts, while surely sincere, are also so simplistically heartwarming that they're misleading -- bowing to America's impulse to see certain black lives as a balm for the bruises of the political moment.
  • Consider the congressman's relationship with President Donald Trump. In March 2017, when the administration was only a few months old, Cummings met with Trump in the Oval Office. The two reportedly spoke openly about race, with the former explaining how the latter's comments about black communities, which he had characterized as poverty-addled hellscapes, were "insulting" and that "probably nobody (had) ever told (him) that."
  • Rather than retreat into defensiveness, Trump replied: "You're right -- nobody has ever told me that."
  • "To know our whites is to understand the psychology of white people and the elasticity of whiteness. It is to be intimate with some white persons but to critically withhold faith in white people categorically," Cottom explained. "It is to anticipate white people's emotions and fears and grievances because their issues are singularly our problem. To know our whites is to survive without letting bitterness rot your soul."

Understanding Culture is the Key to Learning a Language - 0 views

  • If we look at language as simply a network of words and phrases, language learning becomes lifeless and robotic. That doesn’t mean it’s impossible, but such an approach would omit layers of meaning behind the words.
  • Understanding culture puts you in touch with the development and etymologies of the language, such that a culture-free language learning process would never enable the user to fully understand the language, no matter how well they might learn to parrot it.
  • To really unlock a language, to understand it at its roots, understanding culture is key. Here are a few reasons why the two go hand in hand.

  • One of the most heated debates an American can ever get into is talking to an Italian about pizza. The latter might swear up and down that traditional Neapolitan pizza is the only legitimate form of the food.
  • Few elements of language expose a cultural worldview better than idioms. In fact, understanding culture and language is achievable in fast forward just by learning idioms.
  • Even the way we speak languages is part of culture. Korean uses the front of the mouth, and is very direct. Speaking a Korean sentence is like throwing a dart. Dak! It’s pointed and quick. American English is the half-swallowed drawl of a standoffish cowboy. It sits in the back of the throat, leaning against the bar, and barely engages the lips.

4 Everyday Items Einstein Helped Create - 0 views

  • Albert Einstein is justly famous for devising his theory of relativity, which revolutionized our understanding of space, time, gravity, and the universe. Relativity also showed us that matter and energy are just two different forms of the same thing—a fact that Einstein expressed as E=mc2, the most widely recognized equation in history.
  • Credit for inventing paper towels goes to the Scott Paper Company of Pennsylvania, which introduced the disposable product in 1907 as a more hygienic alternative to cloth towels. But in the very first physics article that Einstein ever published, he did analyze wicking: the phenomenon that allows paper towels to soak up liquids even when gravity wants to drag the fluid downward.
  • Again, Einstein didn’t invent solar cells; the first crude versions of them date back to 1839. But he did sketch out their basic principle of operation in 1905. His starting point was a simple analogy: If matter is lumpy—that is, if every substance in the universe consists of atoms and molecules—then surely light must be lumpy as well.
  • ...5 more annotations...
  • Einstein turned this insight into an equation that described the jittering mathematically. His Brownian motion paper is widely recognized as the first incontrovertible proof that atoms and molecules really exist—and it still serves as the basis for some stock market forecasts.
  • He was trying to explain an odd fact that was first noticed by English botanist Robert Brown in 1827. Brown looked through his microscope and saw that the dust grains in a droplet of water were jittering around aimlessly. This Brownian motion, as it was first dubbed, had nothing to do with the grains being alive, so what kept them moving?
  • If you’ve been to a conference or played with a cat, chances are you’ve seen a laser pointer in action. In the nearly six decades since physicists demonstrated the first laboratory prototype of a laser in 1960, the devices have come to occupy almost every niche imaginable, from barcode readers to systems for hair removal.
  • So Einstein made an inspired guess: Maybe photons like to march in step, so that the presence of a bunch of them going in the same direction will increase the probability of a high-energy atom emitting another photon in that direction. He called this process stimulated emission, and when he included it in his equations, his calculations fit the observations perfectly
  • A laser is just a gadget for harnessing this phenomenon
