Stanford Magazine - History Detected - May/June 2013 - 2 views

  • an approach developed at Stanford's Graduate School of Education that's rapidly gaining adherents across the country
  • trial studies of the Stanford program demonstrated that when high school students engage regularly with challenging primary source documents, they not only make significant gains learning and retaining historical material, they also markedly improve their reading comprehension and critical thinking.
  • Colglazier builds his thought-provoking classes using an online tool called Reading Like a Historian. Designed by the Stanford History Education Group under Professor Sam Wineburg, the website offers 87 flexible lesson plans featuring documents from the Library of Congress
  • ...15 more annotations...
  • "Textbooks are useful as background narrative. It's difficult to talk about the Gulf of Tonkin Resolution if students don't know where Vietnam is, or the Lincoln-Douglas debates if they don't know who Abe Lincoln was before he was Daniel Day-Lewis.
  • The website's lessons have been downloaded 800,000 times and spawned a lively online community of history educators grateful for the camaraderie
  • just 30 percent of the people who teach history-related courses in U.S. public high schools both majored in the field and are certified to teach it.
  • " By reading these challenging documents and discovering history for themselves, he says, "not only will they remember the content, they'll develop skills for life."
  • Teachers can download the lessons and adapt them for their own purposes, free of charge. Students learn how to examine documents critically, just as historians would, in order to answer intriguing questions: Did Pocahontas really rescue John Smith? Was Abraham Lincoln a racist? Who blinked first in the Cuban Missile Crisis, the Russians or the Americans?
  • But when a ten-pound textbook becomes the script for a whole year's worth of instruction, a precious learning opportunity is lost. "Many students go through their entire middle and high school and never encounter the actual voice of a historical participant,"
  • The Common Core curriculum will bring radical changes in the standardized state tests that youngsters have been taking for decades. Instead of filling in multiple-choice bubbles, they will be expected to write out short answers that demonstrate their ability to analyze texts, and then cite those texts to support arguments—the exact skills that Reading Like a Historian fosters.
  • Wineburg realized that the art of historical thinking is not something that comes naturally to most people; it has to be cultivated. Students have to be taught to look at the source of a document before reading it, figure out the context in which it was written, and cross-check it with other sources before coming to a conclusion.
  • In 2008, Reisman was ready to conduct a test of the curriculum at five schools in the San Francisco Unified School District. As expected, students in the test classes showed an increased ability to retain historical knowledge, as well as a greater appreciation for history, compared to the control group. What took everyone by surprise, though, was how much the test students advanced in basic reading.
  • Fremont 11th grader Ayanna Black agrees. "In other history courses I have taken, I wasn't able to fully understand what was going on. It seemed that it was just a bunch of words I had to memorize for a future test," she says. "Now that I contextualize the information I am given, it helps me understand not only what is being said but also the reason behind it." The approach, she says, "leads me to remembering the information out of curiosity, rather than trying to pass a test."
  • Scholars in the Stanford History Education Group hope to develop more online lesson plans in world history
  • Wineburg devoured history books as a kid and did well in Advanced Placement courses at his public high school. But when he entered Brown University, he was shocked at how ill-prepared he was in the subject. Employed after college as a high school history teacher, he saw similar weaknesses in his students. "The best ones could repeat what the text said," he recalls, "but when I asked them to critically examine whether they believed the text, I could have been speaking Martian."
  • Wineburg and his PhD students have teamed up with the library on another project: a website called Beyond the Bubble,where teachers can learn how to evaluate their students using short written tests called History Assessments of Thinking. Each HAT asks students to consider a historical document—a letter drawn from the archives of the NAACP, for example—and justify their conclusions about it in three or four sentences. By scanning the responses, teachers can determine quickly whether their pupils are grasping basic concepts.
  • Wineburg hopes to make Reading Like a Historian lesson plans completely paperless, with exercise sheets that can be filled out on a laptop or tablet computer.
  • Though the work has been hard in history this year, she appreciates what it's taught her. "I've learned that you don't just read what is put in front of you and accept it, which is what I had been doing with my textbook all summer," she explains. "It can be frustrating to analyze documents that are contradictory, but I'm coming to appreciate that history is a collection of thousands of accounts and perspectives, and it's our job to interpret it."

The Faulty Logic of the 'Math Wars' - NYTimes.com - 0 views

  • The American philosopher Wilfrid Sellars was challenging this assumption when he spoke of “material inferences.” Sellars was interested in inferences that we can only recognize as valid if we possess certain bits of factual knowledge.
  • If we make room for such material inferences, we will be inclined to reject the view that individuals can reason well without any substantial knowledge of, say, the natural world and human affairs. We will also be inclined to regard the specifically factual content of subjects such as biology and history as integral to a progressive education.
  • according to Wittgenstein, is why it is wrong to understand algorithm-based calculations as expressions of nothing more than “mental mechanisms.” Far from being genuinely mechanical, such calculations involve a distinctive kind of thought.
  • ...3 more annotations...
  • That the use of standard algorithms isn’t merely mechanical is not by itself a reason to teach them. It is important to teach them because, as we already noted, they are also the most elegant and powerful methods for specific operations. This means that they are our best representations of connections among mathematical concepts. Math instruction that does not teach both that these algorithms work and why they do is denying students insight into the very discipline it is supposed to be about.
  • There is a moral here for progressive education that reaches beyond the case of math. Even if we sympathize with progressivists in wanting schools to foster independence of mind, we shouldn’t assume that it is obvious how best to do this. Original thought ranges over many different domains, and it imposes divergent demands as it does so. Just as there is good reason to believe that in biology and history such thought requires significant factual knowledge, there is good reason to believe that in mathematics it requires understanding of and facility with the standard algorithms.
  • there is also good reason to believe that when we examine further areas of discourse we will come across yet further complexities. The upshot is that it would be naïve to assume that we can somehow promote original thinking in specific areas simply by calling for subject-related creative reasoning

¿Por qué tosemos más en los conciertos de música clásica? - BBC Mundo - Noticias - 0 views

  • Todo está en silencio. Los instrumentos de cuerda, los de viento y percusión esperan la señal del director para empezar la pieza. Al otro lado está el público callado, tragando más espeso y conteniendo la tos. Hay alguien que no lo puede evitar y con el primer acorde empieza a toser. ¿Por qué siempre ocurre esto?
  • "Toda la estadística existente sugiere que la gente tose dos veces más durante los conciertos", le dijo Wagener a la BBC.
  • El especialista descubrió que la acción de toser no es completamente aleatoria. La pieza que se escucha también incita a toser más o menos.
  • ...8 more annotations...
  • "Si se trata de conciertos más modernos, como por ejemplo música clásica del siglo XX, los movimientos más lentos y los silencios son interrumpidos con mayor frecuencia".
  • cuando alguien empieza a toser y contagia a los otros.
  • "Creo que muchas personas cuando van a conciertos clásicos se dan cuenta que el nivel de ruido es mucho menor que la música a la que están acostumbradas a oir a través de sus auriculares o conciertos de música pop", agregó la pianista.
  • ese silencio en los conciertos acústicos es reconfortante, para otros puede originar inconformidad que se manifiesta en la acción de toser.
  • Andreas Wagener se mostró parcialmente de acuerdo con la teoría de Tomes, pues "cuando alguien va a un concierto (de música clásica) sabe que debe permanecer en silencio".
  • "Es una cuestión de etiqueta, saben que no deben hablar o caminar, hacer ruido o toser, pero la gente sigue tosiendo en exceso".
  • con la tos no se puede saber si es deliberado o involuntario.
  • "Creo que a veces la gente no esta consciente de como suena para el concertista. Es un factor muy distractor".
  •  
    I realize that this article is in Spanish, so those who don't understand the language will likely be confused, but I thought that it was very interesting, and related to TOK. Essentially, the article talked about a study that Andreas Wagener, a German scientist did, in which it was discovered that people cough twice as much at classical music concerts than otherwise. Wagener also found that the amount of coughing was not random; rather, it was dependent on the style, tempo, etc. of the music being played. The slow, more modern pieces often elicited more coughs. Additionally, Wagener found that, similar to how we think about yawning, coughing is contagious; one cough can cause an avalanche of other coughs. The article also noted the possibility that some of the coughing going on during a classical music concert may not be the typical, involuntary, reflexive cough, but a deliberate cough of social interaction. In terms of TOK, I thought that this article was most interesting in that, when put into a situation in which we may be uncomfortable (often with silence), we cough more. I related this to my own experiences at Friends, during MFW, when people often seem to cough out of a need for interaction. It would be interesting to see if Wagener could work with some geneticists and biologists to discover if a connection between slow classical music and more coughing is purely biological, or if it stems from another causation of human behavior.

Hillary Clinton explains why she won't say 'radical Islam' - CNNPolitics.com - 0 views

  • "radical Islam" because it "sounds like we are declaring war against a religion."
  • It doesn't do justice to the vast number of Muslims in our country and around the world who are peaceful people,"
  • "Now when you say radical Islamic jihadist, they understand, the rest of the Muslim community understands. The folks who are peaceful and who attend mosques in a peaceful way, work in our country, raise their families, pay their taxes. They know they're not radical Islamic jihadists."

Rick Perry: The truth about 'American Sniper' Chris Kyle | Fox News - 0 views

  • Despite the high regard in which Americans have held the military for generations, there is a lot about the military that those who haven’t served don’t quite understand.
  • That gap of understanding between the protected and their protectors is typically bridged by mutual respect, but can also be a gutter in which liars and character assassins slither.
  • As any veteran will tell you, a DD-214 is THE definitive record of a person’s time in the military, used to prove the authenticity, duration and character of said service.  The official name for the form is Certificate of Release or Discharge from Active Duty and veterans learn early on to keep a copy handy.

Understanding the Emotional Response · An A List Apart Article - 0 views

  • Validating emotions isn’t a glorified psychological process. It’s about being a real, authentic human being who empathizes with another’s emotional state. And, guess what, that’s damn hard.
  • Some of the most delicate emotional responses we run into surface when people experience identity issues
  • The good news is we can boost worth with seemingly simple things like listening and letting people be themselves.

Immanuel Kant - Wikipedia, the free encyclopedia - 0 views

  • the agreement between reality and the concepts we use to conceive it arises not because our mental concepts have come to passively mirror reality, but because reality must conform to the human mind's active concepts to be conceivable and at all possible for us to experience. Kant thus regarded the basic categories of the human mind as the transcendental "condition of possibility" for any experience.[6]
  •  
    Kant, german philosopher, argues that reality must conform to the mind, rather than the mind conform to reality, for us to begin to understand it. Interesting way to think about our perception.   (Evie, 9/23/16)

  • Persuasion plays a crucial role in successful conflict resolution.  The authors explain, "negotiated settlements most typically fall apart if the parties to the settlement do not truly believe that it is in their self-interest.  For a negotiated settlement to stand the test of time, both parties have to be persuaded that the settlement is in some sense optimal."(p. 157) Negotiators will be more persuasive if they understand which type of information processing is predominates at each particular stage of negotiations, and if they formulate their persuasive appeals in light of that understanding.
  •  
    This article on conflict resolution speaks on the value of persuasion, in its integral role in conflict resolution, rather than the discrete, logical argumentation Novella promotes. This excerpt shows how one can persuade by just tapping into the right desire in an effective way, without requiring a logical approach--revealing how emotion precedes rationality in the human mind.  10/17/16 - Evie K

Your Dog Remembers More Than You Think - The New York Times - 0 views

  • In people it is called episodic memory, and it involves a sense of self. In animals, it’s called episodic-like memory, because it’s difficult to try to plumb something as elusive as self without the aid of language.
  • Dr. Fugazza and colleagues reported online in Current Biology that this showed that the dogs remembered an event they hadn’t been concentrating on, the trainer’s action. She said one aspect strengthened that conclusion: The dogs tended to lie down immediately when they got back to the mat, suggesting that their heads were in “lie down” mode, not “do it” mode.
  • He said human episodic memory is lost in Alzheimer’s disease and he and others study animal memory in hopes of learning how to combat that loss. The work on dogs offers a new technique that could be very useful, he said.
  •  
    I found this experiment very interesting because it shows some aspect of how animals memory works. The result can be used to see how memory work without language. I think language and memory have an intertwined relationship because sometimes I can feel that the information stored in my brain is in language rather than abstract form such as knowledge. For example, my memory of chemistry knowledge is stored in English, so when I am reading a chemistry related book in Chinese, I would usually get lost because there aren't any vocals on Chemistry in Chinese in my memory. It would be a very interesting question to consider that how our memory will construct if we don't have a language. There is a kind of mental disease called "aphasia", meaning the loss of ability to understand language. How do they remember things when they lose the ability to assign meanings and communicate? --Sissi (11/24/2016)

Language family - Wikipedia - 0 views

  • A language family is a group of languages related through descent from a common ancestor, called the proto-language of that family. The term 'family' reflects the tree model of language origination in historical linguistics, which makes use of a metaphor comparing languages to people in a biological family tree, or in a subsequent modification, to species in a phylogenetic tree of evolutionary taxonomy.
  • the Celtic, Germanic, Slavic, Romance, and Indo-Iranian language families are branches of a larger Indo-European language family. There is a remarkably similar pattern shown by the linguistic tree and the genetic tree of human ancestry[3] that was verified statistically.
  • A speech variety may also be considered either a language or a dialect depending on social or political considerations. Thus, different sources give sometimes wildly different accounts of the number of languages within a family. Classifications of the Japonic family, for example, range from one language (a language isolate) to nearly twenty.
  • ...2 more annotations...
  • A language isolated in its own branch within a family, such as Armenian within Indo-European, is often also called an isolate, but the meaning of isolate in such cases is usually clarified. For instance, Armenian may be referred to as an "Indo-European isolate". By contrast, so far as is known, the Basque language is an absolute isolate: it has not been shown to be related to any other language despite numerous attempts.
  • The common ancestor of a language family is seldom known directly since most languages have a relatively short recorded history. However, it is possible to recover many features of a proto-language by applying the comparative method, a reconstructive procedure worked out by 19th century linguist August Schleicher.
  •  
    I found this metaphor very accurate because I think languages certainly have some intimate relationship like family members. Languages are not all very different from one another and isolated. Although people speaking different language may not understand one another, their languages are still connected. I think this article can show that language in some ways are connected like bridges instead of walls. --Sissi (11/26/2016)

The Mistrust of Science - The New Yorker - 0 views

  • The Mistrust of Science
  • The scientific orientation has proved immensely powerful. It has allowed us to nearly double our lifespan during the past century, to increase our global abundance, and to deepen our understanding of the nature of the universe. Yet scientific knowledge is not necessarily trusted. Partly, that’s because it is incomplete. But even where the knowledge provided by science is overwhelming, people often resist it—sometimes outright deny it. Many people continue to believe, for instance, despite massive evidence to the contrary, that childhood vaccines cause autism (they do not); that people are safer owning a gun (they are not); that genetically modified crops are harmful (on balance, they have been beneficial); that climate change is not happening (it is).
  • People are prone to resist scientific claims when they clash with intuitive beliefs. They don’t see measles or mumps around anymore. They do see children with autism. And they see a mom who says, “My child was perfectly fine until he got a vaccine and became autistic.”
  • ...1 more annotation...
  • Even more than what you think, how you think matters. The stakes for understanding this could not be higher than they are today, because we are not just battling for what it means to be scientists. We are battling for what it means to be citizens.

U.S. Will Ban Smoking in Public Housing Nationwide - The New York Times - 0 views

  • The final rule followed a period of public comment during which some opponents took exception to the government’s telling people what to do in the privacy of their own homes.
  • In New York, there was also concern about whether police officers would be involved in enforcing the rule; that will not be the case, Housing Authority officials said.
  • “Public housing will go smoke-free and remain smoke-free, and, because of that,” he said, “so many folks are going to live healthier lives and have a better shot at reaching their dreams because they have good health.”
  •  
    Banning smoking in public housing is still a controversial issue because it touch on whether we have the freedom to decide what we do at home. I think this issue shows that how our freedom is limited in this society. To what extent can we have our own privacy is still a debatable question because we all have a different understanding on how we are related to other people in this society. Or even do we really have privacy? As social animals, we are meant to stay in groups. Also, the last statement of this article sound like a logical fallacy because having a good health and having a better shot at reaching dreams don't really have that much direct relation. I think it is just a small factor. --Sissi (12/1/2016)

Covering politics in a "post-truth" America | Brookings Institution - 0 views

  • The media scandal of 2016 isn’t so much about what reporters failed to tell the American public; it’s about what they did report on, and the fact that it didn’t seem to matter.
  • Facebook and Snapchat and the other social media sites should rightfully be doing a lot of soul-searching about their role as the most efficient distribution network for conspiracy theories, hatred, and outright falsehoods ever invented.
  • I’ve been obsessively looking back over our coverage, too, trying to figure out what we missed along the way to the upset of the century
  • ...28 more annotations...
  • (An early conclusion: while we were late to understand how angry white voters were, a perhaps even more serious lapse was in failing to recognize how many disaffected Democrats there were who would stay home rather than support their party’s flawed candidate.)
  • Stories that would have killed any other politician—truly worrisome revelations about everything from the federal taxes Trump dodged to the charitable donations he lied about, the women he insulted and allegedly assaulted, and the mob ties that have long dogged him—did not stop Trump from thriving in this election year
  • the Oxford Dictionaries announced that “post-truth” had been chosen as the 2016 word of the year, defining it as a condition “in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief.”
  • Meantime, Trump personally blacklisted news organizations like Politico and The Washington Post when they published articles he didn’t like during the campaign, has openly mused about rolling back press freedoms enshrined by the U.S. Supreme Court, and has now named Stephen Bannon, until recently the executive chairman of Breitbart—a right-wing fringe website with a penchant for conspiracy theories and anti-Semitic tropes—to serve as one of his top White House advisers.
  • none of this has any modern precedent. And what makes it unique has nothing to do with the outcome of the election. This time, the victor was a right-wing demagogue; next time, it may be a left-wing populist who learns the lessons of Trump’s win.
  • This is no mere academic argument. The election of 2016 showed us that Americans are increasingly choosing to live in a cloud of like-minded spin, surrounded by the partisan political hackery and fake news that poisons their Facebook feeds.
  • To help us understand it all, there were choices, but not that many: three TV networks that mattered, ABC, CBS, and NBC; two papers for serious journalism, The New York Times and The Washington Post; and two giant-circulation weekly newsmagazines, Time and Newsweek. That, plus whatever was your local daily newspaper, pretty much constituted the news.
  • Fake news is thriving In the final three months of the presidential campaign, the 20 top-performing fake election news stories generated more engagement on Facebook than the top stories from major news outlets such as The New York Times.
  • Eventually, I came to think of the major media outlets of that era as something very similar to the big suburban shopping malls we flocked to in the age of shoulder pads and supply-side economics: We could choose among Kmart and Macy’s and Saks Fifth Avenue as our budgets and tastes allowed, but in the end the media were all essentially department stores, selling us sports and stock tables and foreign news alongside our politics, whether we wanted them or not. It may not have been a monopoly, but it was something pretty close.
  • This was still journalism in the scarcity era, and it affected everything from what stories we wrote to how fast we could produce them. Presidents could launch global thermonuclear war with the Russians in a matter of minutes, but news from the American hinterlands often took weeks to reach their sleepy capital. Even information within that capital was virtually unobtainable without a major investment of time and effort. Want to know how much a campaign was raising and spending from the new special-interest PACs that had proliferated? Prepare to spend a day holed up at the Federal Election Commission’s headquarters down on E Street across from the hulking concrete FBI building, and be sure to bring a bunch of quarters for the copy machine.
  • I am writing this in the immediate, shocking aftermath of a 2016 presidential election in which the Pew Research Center found that a higher percentage of Americans got their information about the campaign from late-night TV comedy shows than from a national newspaper. Don Graham sold the Post three years ago and though its online audience has been skyrocketing with new investments from Amazon.com founder Jeff Bezos, it will never be what it was in the ‘80s. That same Pew survey reported that a mere 2 percent of Americans today turned to such newspapers as the “most helpful” guides to the presidential campaign.
  • In 2013, Mark Leibovich wrote a bestselling book called This Town about the party-hopping, lobbyist-enabling nexus between Washington journalists and the political world they cover. A key character was Politico’s Mike Allen, whose morning email newsletter “Playbook” had become a Washington ritual, offering all the news and tidbits a power player might want to read before breakfast—and Politico’s most successful ad franchise to boot. In many ways, even that world of just a few years ago now seems quaint: the notion that anyone could be a single, once-a-day town crier in This Town (or any other) has been utterly exploded by the move to Twitter, Facebook, and all the rest. We are living, as Mark put it to me recently, “in a 24-hour scrolling version of what ‘Playbook’ was.”
  • Whether it was Walter Cronkite or The New York Times, they preached journalistic “objectivity” and spoke with authority when they pronounced on the day’s developments—but not always with the depth and expertise that real competition or deep specialization might have provided. They were great—but they were generalists.
  • I remained convinced that reporting would hold its value, especially as our other advantages—like access to information and the expensive means to distribute it—dwindled. It was all well and good to root for your political team, but when it mattered to your business (or the country, for that matter), I reasoned, you wouldn’t want cheerleading but real reporting about real facts. Besides, the new tools might be coming at us with dizzying speed—remember when that radical new video app Meerkat was going to change absolutely everything about how we cover elections?—but we would still need reporters to find a way inside Washington’s closed doors and back rooms, to figure out what was happening when the cameras weren’t rolling.
  • And if the world was suffering from information overload—well, so much the better for us editors; we would be all the more needed to figure out what to listen to amid the noise.
  • Trump turned out to be more correct than we editors were: the more relevant point of the Access Hollywood tape was not about the censure Trump would now face but the political reality that he, like Bill Clinton, could survive this—or perhaps any scandal. Yes, we were wrong about the Access Hollywood tape, and so much else.
  • These days, Politico has a newsroom of 200-odd journalists, a glossy award-winning magazine, dozens of daily email newsletters, and 16 subscription policy verticals. It’s a major player in coverage not only of Capitol Hill but many other key parts of the capital, and some months during this election year we had well over 30 million unique visitors to our website, a far cry from the controlled congressional circulation of 35,000 that I remember Roll Call touting in our long-ago sales materials.
  • , we journalists were still able to cover the public theater of politics while spending more of our time, resources, and mental energy on really original reporting, on digging up stories you couldn’t read anywhere else. Between Trump’s long and checkered business past, his habit of serial lying, his voluminous and contradictory tweets, and his revision of even his own biography, there was lots to work with. No one can say that Trump was elected without the press telling us all about his checkered past.
  • politics was NEVER more choose-your-own-adventure than in 2016, when entire news ecosystems for partisans existed wholly outside the reach of those who at least aim for truth
  • Pew found that nearly 50 percent of self-described conservatives now rely on a single news source, Fox, for political information they trust.
  • As for the liberals, they trust only that they should never watch Fox, and have MSNBC and Media Matters and the remnants of the big boys to confirm their biases.
  • And then there are the conspiracy-peddling Breitbarts and the overtly fake-news outlets of this overwhelming new world; untethered from even the pretense of fact-based reporting, their version of the campaign got more traffic on Facebook in the race’s final weeks than all the traditional news outlets combined.
  • When we assigned a team of reporters at Politico during the primary season to listen to every single word of Trump’s speeches, we found that he offered a lie, half-truth, or outright exaggeration approximately once every five minutes—for an entire week. And it didn’t hinder him in the least from winning the Republican presidential nomination.
  • when we repeated the exercise this fall, in the midst of the general election campaign, Trump had progressed to fibs of various magnitudes just about once every three minutes!
  • By the time Trump in September issued his half-hearted disavowal of the Obama “birther” whopper he had done so much to create and perpetuate, one national survey found that only 1 in 4 Republicans was sure that Obama was born in the U.S., and various polls found that somewhere between a quarter and a half of Republicans believed he’s Muslim. So not only did Trump think he was entitled to his own facts, so did his supporters. It didn’t stop them at all from voting for him.
  • in part, it’s not just because they disagree with the facts as reporters have presented them but because there’s so damn many reporters, and from such a wide array of outlets, that it’s often impossible to evaluate their standards and practices, biases and preconceptions. Even we journalists are increasingly overwhelmed.
  • So much terrific reporting and writing and digging over the years and … Trump? What happened to consequences? Reporting that matters? Sunlight, they used to tell us, was the best disinfectant for what ails our politics.
  • 2016 suggests a different outcome: We’ve achieved a lot more transparency in today’s Washington—without the accountability that was supposed to come with it.

What Happened Before the Big Bang? The New Philosophy of Cosmology - Ross Andersen - Te... - 1 views

  • This question of accounting for what we call the "big bang state" -- the search for a physical explanation of it -- is probably the most important question within the philosophy of cosmology, and there are a couple different lines of thought about it.
  • One that's becoming more and more prevalent in the physics community is the idea that the big bang state itself arose out of some previous condition, and that therefore there might be an explanation of it in terms of the previously existing dynamics by which it came about
  • The problem is that quantum mechanics was developed as a mathematical tool. Physicists understood how to use it as a tool for making predictions, but without an agreement or understanding about what it was telling us about the physical world. And that's very clear when you look at any of the foundational discussions. This is what Einstein was upset about; this is what Schrodinger was upset about. Quantum mechanics was merely a calculational technique that was not well understood as a physical theory. Bohr and Heisenberg tried to argue that asking for a clear physical theory was something you shouldn't do anymore. That it was something outmoded. And they were wrong, Bohr and Heisenberg were wrong about that. But the effect of it was to shut down perfectly legitimate physics questions within the physics community for about half a century. And now we're coming out of that

  • One common strategy for thinking about this is to suggest that what we used to call the whole universe is just a small part of everything there is, and that we live in a kind of bubble universe, a small region of something much larger
  • Newton realized there had to be some force holding the moon in its orbit around the earth, to keep it from wandering off, and he knew also there was a force that was pulling the apple down to the earth. And so what suddenly struck him was that those could be one and the same thing, the same force
  • That was a physical discovery, a physical discovery of momentous importance, as important as anything you could ever imagine because it knit together the terrestrial realm and the celestial realm into one common physical picture. It was also a philosophical discovery in the sense that philosophy is interested in the fundamental natures of things.
  • There are other ideas, for instance that maybe there might be special sorts of laws, or special sorts of explanatory principles, that would apply uniquely to the initial state of the universe.
  • The basic philosophical question, going back to Plato, is "What is x?" What is virtue? What is justice? What is matter? What is time? You can ask that about dark energy - what is it? And it's a perfectly good question.
  • right now there are just way too many freely adjustable parameters in physics. Everybody agrees about that. There seem to be many things we call constants of nature that you could imagine setting at different values, and most physicists think there shouldn't be that many, that many of them are related to one another. Physicists think that at the end of the day there should be one complete equation to describe all physics, because any two physical systems interact and physics has to tell them what to do. And physicists generally like to have only a few constants, or parameters of nature. This is what Einstein meant when he famously said he wanted to understand what kind of choices God had --using his metaphor-- how free his choices were in creating the universe, which is just asking how many freely adjustable parameters there are. Physicists tend to prefer theories that reduce that number
  • You have others saying that time is just an illusion, that there isn't really a direction of time, and so forth. I myself think that all of the reasons that lead people to say things like that have very little merit, and that people have just been misled, largely by mistaking the mathematics they use to describe reality for reality itself. If you think that mathematical objects are not in time, and mathematical objects don't change -- which is perfectly true -- and then you're always using mathematical objects to describe the world, you could easily fall into the idea that the world itself doesn't change, because your representations of it don't.
  • physicists for almost a hundred years have been dissuaded from trying to think about fundamental questions. I think most physicists would quite rightly say "I don't have the tools to answer a question like 'what is time?' - I have the tools to solve a differential equation." The asking of fundamental physical questions is just not part of the training of a physicist anymore.
  • The question remains as to how often, after life evolves, you'll have intelligent life capable of making technology. What people haven't seemed to notice is that on earth, of all the billions of species that have evolved, only one has developed intelligence to the level of producing technology. Which means that kind of intelligence is really not very useful. It's not actually, in the general case, of much evolutionary value. We tend to think, because we love to think of ourselves, human beings, as the top of the evolutionary ladder, that the intelligence we have, that makes us human beings, is the thing that all of evolution is striving toward. But what we know is that that's not true. Obviously it doesn't matter that much if you're a beetle, that you be really smart. If it were, evolution would have produced much more intelligent beetles. We have no empirical data to suggest that there's a high probability that evolution on another planet would lead to technological intelligence.

Apple removed the New York Times app in China. Why now? - LA Times - 0 views

  • California’s Internet companies may have once dreamed of liberating China through technology, but these days they seem more willing than ever to play the Communist Party's game
  • "This is a restoration of the Cultural Revolution or another historical retrogression," said another.
  • The Washington Post is one of many Western newspapers that carries a regular paid supplement by China Daily, another Communist Party mouthpiece.
  •  
    The censorship in China has long been a controversial issue that's widely discussed. I think it's very natural that those internet companies play the government the rules to enter the Chinese market because most companies are profit-driven rather than being all idealistic. However, I found the tone of this article very uncomfortable. He used the word "liberating" as if China is in bad condition or great suffer that need American freedom to save. Also, looking back to American history, American heroism plays a big part in what the American government did. They "liberated" Canada, "liberated" Vietnam, "liberated" Pakistan, and now America tries to "liberate" China. However, they never fully understand the pros and cons of censorship and how China is a totally different country to America. One's medicine can toxic for another. --Sissi (1/6/2017)

Donald Trump will win in a landslide. *The mind behind 'Dilbert' explains why. - The Wa... - 0 views

  • What the Bay Area-based cartoonist recognizes, he says, is the careful art behind Trump’s rhetorical techniques.
  • Adams believes Trump will win because he’s “a master persuader.”
  • His stated credentials in this arena, says Adams — who holds an MBA from UC Berkeley — largely involve being a certified hypnotist and, as a writer and business author, an eternal student in the techniques of persuasive rhetoric.
  • ...18 more annotations...
  • “The most important thing when you study hypnosis is that you learn that humans are irrational,
  • what Trump is doing? He is acknowledging the suffering of some, Adams says, and then appealing emotionally to that.
  • 2. Knowing that people are irrational, Trump aims to appeal on an emotional level.
  • Having nothing to lose essentially then increases his chance of winning, because it opens up his field of rhetorical play.
  • Within that context, here is what Candidate Trump is doing to win campaign hearts and minds
  • 1. Trump knows people are basically irrational.
  • he bolsters that approach, Adams says, by “exploiting the business model” like an entrepreneur. In this model, which “the news industry doesn’t have the ability to change … the media doesn’t really have the option of ignoring the most interesting story,” says Adams, contending that Trump “can always be the most interesting story if he has nothing to fear and nothing to lose.”
  • “The evidence is that Trump completely ignores reality and rational thinking in favor of emotional appeal,” Adams writes. “Sure, much of what Trump says makes sense to his supporters, but I assure you that is coincidence. Trump says whatever gets him the result he wants. He understands humans as 90-percent irrational and acts accordingly.”
  • 3. By running on emotion, facts don’t matter.
  • “There are plenty of important facts Trump does not know. But the reason he doesn’t know those facts is – in part – because he knows facts don’t matter. They never have and they never will. So he ignores them.
  • 4. If facts don’t matter, you can’t really be “wrong.”
  • “If you understand persuasion, Trump is pitch-perfect most of the time. He ignores unnecessary rational thought and objective data and incessantly hammers on what matters (emotions).”
  • “Did Trump’s involvement in the birther thing confuse you?” Adams goes on to ask. “Were you wondering how Trump could believe Obama was not a citizen? The answer is that Trump never believed anything about Obama’s place of birth. The facts were irrelevant, so he ignored them while finding a place in the hearts of conservatives.
  • 5. With fewer facts in play, it’s easier to bend reality.
  • Among the persuasive techniques that Trump uses to help bend reality, Adams says, are repetition of phrases; “thinking past the sale” so the initial part of his premise is stated as a given; and knowing the appeal of the simplest answer, which relates to the concept of Occam’s razor.
  • 6. To bend reality, Trump is a master of identity politics — and identity is the strongest persuader.
  • “The best Trump linguistic kill shots,” Adams writes,”have the following qualities: 1. Fresh word that is not generally used in politics; 2. Relates to the physicality of the subject (so you are always reminded).”
  • : “Identity is always the strongest level of persuasion. The only way to beat it is with dirty tricks or a stronger identity play. … [And] Trump is well on his way to owning the identities of American, Alpha Males, and Women Who Like Alpha Males. Clinton is well on her way to owning the identities of angry women, beta males, immigrants, and disenfranchised minorities.

Why You Will Marry the Wrong Person - The New York Times - 1 views

  • IT’S one of the things we are most afraid might happen to us. We go to great lengths to avoid it. And yet we do it all the same: We marry the wrong person.
  • Partly, it’s because we have a bewildering array of problems that emerge when we try to get close to others. We seem normal only to those who don’t know us very well. In a wiser, more self-aware society than our own, a standard question on any early dinner date would be: “And how are you crazy?
  • Marriage ends up as a hopeful, generous, infinitely kind gamble taken by two people who don’t know yet who they are or who the other might be, binding themselves to a future they cannot conceive of and have carefully avoided investigating.
  • ...18 more annotations...
  • For most of recorded history, people married for logical sorts of reasons:
  • And from such reasonable marriages, there flowed loneliness, infidelity, abuse, hardness of heart and screams heard through the nursery doors
  • The marriage of reason was not, in hindsight, reasonable at all; it was often expedient, narrow-minded, snobbish and exploitative. That is why what has replaced it — the marriage of feeling — has largely been spared the need to account for itself
  • Finally, we marry to make a nice feeling permanent. We imagine that marriage will help us to bottle the joy we felt when the thought of proposing first came to us: Perhaps we were in Venice, on the lagoon, in a motorboat
  • But though we believe ourselves to be seeking happiness in marriage, it isn’t that simple. What we really seek is familiarity
  • We are looking to recreate, within our adult relationships, the feelings we knew so well in childhood. The love most of us will have tasted early on was often confused with other, more destructive dynamics: feelings of wanting to help an adult who was out of control, of being deprived of a parent’s warmth or scared of his anger, of not feeling secure enough to communicate our wishes.
  • How logical, then, that we should as grown-ups find ourselves rejecting certain candidates for marriage not because they are wrong but because they are too right — too balanced, mature, understanding and reliable — given that in our hearts, such rightness feels foreign. We marry the wrong people because we don’t associate being loved with feeling happy.
  • We make mistakes, too, because we are so lonely. No one can be in an optimal frame of mind to choose a partner when remaining single feels unbearable. We have to be wholly at peace with the prospect of many years of solitude in order to be appropriately picky
  • What matters in the marriage of feeling is that two people are drawn to each other by an overwhelming instinct and know in their hearts that it is right
  • marriage tends decisively to move us onto another, very different and more administrative plane, which perhaps unfolds in a suburban house, with a long commute and maddening children who kill the passion from which they emerged. The only ingredient in common is the partner. And that might have been the wrong ingredient to bottle.
  • The good news is that it doesn’t matter if we find we have married the wrong person.
  • We mustn’t abandon him or her, only the founding Romantic idea upon which the Western understanding of marriage has been based the last 250 years: that a perfect being exists who can meet all our needs and satisfy our every yearning.
  • WE need to swap the Romantic view for a tragic (and at points comedic) awareness that every human will frustrate, anger, annoy, madden and disappoint us — and we will (without any malice) do the same to them.
  • But none of this is unusual or grounds for divorce. Choosing whom to commit ourselves to is merely a case of identifying which particular variety of suffering we would most like to sacrifice ourselves for.
  • pessimism relieves the excessive imaginative pressure that our romantic culture places upon marriage. The failure of one particular partner to save us from our grief and melancholy is not an argument against that person and no sign that a union deserves to fail or be upgraded.
  • The person who is best suited to us is not the person who shares our every taste (he or she doesn’t exist), but the person who can negotiate differences in taste intelligently — the person who is good at disagreement.
  • Rather than some notional idea of perfect complementarity, it is the capacity to tolerate differences with generosity that is the true marker of the “not overly wrong” person
  • We should learn to accommodate ourselves to “wrongness,” striving always to adopt a more forgiving, humorous and kindly perspective on its multiple examples in ourselves and in our partners.

Wiretapping the senses: Scientists monitor conversation between sensory perception, beh... - 0 views

  • Many types of sensory information enter the brain at a structure called the primary sensory cortex, where they are processed by different layers of cells in ways that ultimately influence an animal's perception and behavioral response.
  • An ultimate goal of neurobiological research is to understand how a brain integrates a constant flow of various types of stimuli, makes sense of it, and helps coordinate an appropriate behavioral respons
  • Understanding the most basic principles of this system will require careful studies of regions of animal brains that are simple enough to keep track of nerve impulses as they enter, and yet complex enough to follow different types of signals as they exit along different routes.

How Did Consciousness Evolve? - The Atlantic - 0 views

  • Theories of consciousness come from religion, from philosophy, from cognitive science, but not so much from evolutionary biology. Maybe that’s why so few theories have been able to tackle basic questions such as: What is the adaptive value of consciousness? When did it evolve and what animals have it?
  • The Attention Schema Theory (AST), developed over the past five years, may be able to answer those questions.
  • The theory suggests that consciousness arises as a solution to one of the most fundamental problems facing any nervous system: Too much information constantly flows in to be fully processed. The brain evolved increasingly sophisticated mechanisms for deeply processing a few select signals at the expense of others, and in the AST, consciousness is the ultimate result of that evolutionary sequence
  • ...23 more annotations...
  • Even before the evolution of a central brain, nervous systems took advantage of a simple computing trick: competition.
  • It coordinates something called overt attention – aiming the satellite dishes of the eyes, ears, and nose toward anything important.
  • Selective enhancement therefore probably evolved sometime between hydras and arthropods—between about 700 and 600 million years ago, close to the beginning of complex, multicellular life
  • The next evolutionary advance was a centralized controller for attention that could coordinate among all senses. In many animals, that central controller is a brain area called the tectum
  • At any moment only a few neurons win that intense competition, their signals rising up above the noise and impacting the animal’s behavior. This process is called selective signal enhancement, and without it, a nervous system can do almost nothing.
  • All vertebrates—fish, reptiles, birds, and mammals—have a tectum. Even lampreys have one, and they appeared so early in evolution that they don’t even have a lower jaw. But as far as anyone knows, the tectum is absent from all invertebrates
  • According to fossil and genetic evidence, vertebrates evolved around 520 million years ago. The tectum and the central control of attention probably evolved around then, during the so-called Cambrian Explosion when vertebrates were tiny wriggling creatures competing with a vast range of invertebrates in the sea.
  • The tectum is a beautiful piece of engineering. To control the head and the eyes efficiently, it constructs something called an internal model, a feature well known to engineers. An internal model is a simulation that keeps track of whatever is being controlled and allows for predictions and planning.
  • The tectum’s internal model is a set of information encoded in the complex pattern of activity of the neurons. That information simulates the current state of the eyes, head, and other major body parts, making predictions about how these body parts will move next and about the consequences of their movement
  • In fish and amphibians, the tectum is the pinnacle of sophistication and the largest part of the brain. A frog has a pretty good simulation of itself.
  • With the evolution of reptiles around 350 to 300 million years ago, a new brain structure began to emerge – the wulst. Birds inherited a wulst from their reptile ancestors. Mammals did too, but our version is usually called the cerebral cortex and has expanded enormously
  • The cortex also takes in sensory signals and coordinates movement, but it has a more flexible repertoire. Depending on context, you might look toward, look away, make a sound, do a dance, or simply store the sensory event in memory in case the information is useful for the future.
  • The most important difference between the cortex and the tectum may be the kind of attention they control. The tectum is the master of overt attention—pointing the sensory apparatus toward anything important. The cortex ups the ante with something called covert attention. You don’t need to look directly at something to covertly attend to it. Even if you’ve turned your back on an object, your cortex can still focus its processing resources on it
  • The cortex needs to control that virtual movement, and therefore like any efficient controller it needs an internal model. Unlike the tectum, which models concrete objects like the eyes and the head, the cortex must model something much more abstract. According to the AST, it does so by constructing an attention schema—a constantly updated set of information that describes what covert attention is doing moment-by-moment and what its consequences are
  • Covert attention isn’t intangible. It has a physical basis, but that physical basis lies in the microscopic details of neurons, synapses, and signals. The brain has no need to know those details. The attention schema is therefore strategically vague. It depicts covert attention in a physically incoherent way, as a non-physical essence
  • this, according to the theory, is the origin of consciousness. We say we have consciousness because deep in the brain, something quite primitive is computing that semi-magical self-description.
  • I’m reminded of Teddy Roosevelt’s famous quote, “Do what you can with what you have where you are.” Evolution is the master of that kind of opportunism. Fins become feet. Gill arches become jaws. And self-models become models of others. In the AST, the attention schema first evolved as a model of one’s own covert attention. But once the basic mechanism was in place, according to the theory, it was further adapted to model the attentional states of others, to allow for social prediction. Not only could the brain attribute consciousness to itself, it began to attribute consciousness to others.
  • In the AST’s evolutionary story, social cognition begins to ramp up shortly after the reptilian wulst evolved. Crocodiles may not be the most socially complex creatures on earth, but they live in large communities, care for their young, and can make loyal if somewhat dangerous pets.
  • If AST is correct, 300 million years of reptilian, avian, and mammalian evolution have allowed the self-model and the social model to evolve in tandem, each influencing the other. We understand other people by projecting ourselves onto them. But we also understand ourselves by considering the way other people might see us.
  • t the cortical networks in the human brain that allow us to attribute consciousness to others overlap extensively with the networks that construct our own sense of consciousness.
  • Language is perhaps the most recent big leap in the evolution of consciousness. Nobody knows when human language first evolved. Certainly we had it by 70 thousand years ago when people began to disperse around the world, since all dispersed groups have a sophisticated language. The relationship between language and consciousness is often debated, but we can be sure of at least this much: once we developed language, we could talk about consciousness and compare notes
  • Maybe partly because of language and culture, humans have a hair-trigger tendency to attribute consciousness to everything around us. We attribute consciousness to characters in a story, puppets and dolls, storms, rivers, empty spaces, ghosts and gods. Justin Barrett called it the Hyperactive Agency Detection Device, or HADD
  • the HADD goes way beyond detecting predators. It’s a consequence of our hyper-social nature. Evolution turned up the amplitude on our tendency to model others and now we’re supremely attuned to each other’s mind states. It gives us our adaptive edge. The inevitable side effect is the detection of false positives, or ghosts.
