Why white supremacists and QAnon enthusiasts are obsessed - but very wrong - about the ... - 0 views

  • Byzantium – or more properly, the medieval Roman Empire – controlled much of the Mediterranean at the height of its territorial rule in the mid-sixth century.
  • His premise is that when Rome fell, the Byzantine Empire went on to preserve a white-European civilization. This isn’t true.
  • Mentions of Byzantium are scattered across message boards frequented by both white supremacists and QAnon enthusiasts – who spout conspiracy theories about a deep-state cabal of Satan-worshipping, blood-drinking pedophiles running the world.

  • “It all makes sense when you learn that the books of the bible are plagiarized copies of the chronology of Byzantium, and so is the mythical Roman Empire, that never existed in Italy but was in fact centered in Constantinople.”
  • In some renditions, Byzantium is, by way of some hazy illuminati connections, the origins of the “deep state” –
  • For many on the far right, talk of Byzantium is cloaked in Islamophobia – both online and in tragic real-life events.
  • This “reconquest” of Constantinople had even been tied in some online posts to the presidency of Donald Trump, with images circulated online seemingly prophesying that it would happen under his tenure.
  • No matter the provenance of the recent interest in Byzantium from America’s white supremacists and conspiracy theorists, one thing is clear: It is based on a very warped idea of the Byzantine Empire that has emerged out of the empire’s fraught place in our histories, caught between ancient and medieval, spirituality and bureaucracy.

Facebook's Bias Is Built-In, and Bears Watching - The New York Times - 2 views

  • Facebook is the world’s most influential source of news.That’s true according to every available measure of size — the billion-plus people who devour its News Feed every day, the cargo ships of profit it keeps raking in, and the tsunami of online traffic it sends to other news sites.
  • But Facebook has also acquired a more subtle power to shape the wider news business. Across the industry, reporters, editors and media executives now look to Facebook the same way nesting baby chicks look to their engorged mother — as the source of all knowledge and nourishment, the model for how to behave in this scary new-media world. Case in point: The New York Times, among others, recently began an initiative to broadcast live video. Why do you suppose that might be? Yup, the F word. The deal includes payments from Facebook to news outlets, including The Times.
  • Yet few Americans think of Facebook as a powerful media organization, one that can alter events in the real world. When blowhards rant about the mainstream media, they do not usually mean Facebook, the mainstreamiest of all social networks. That’s because Facebook operates under a veneer of empiricism. Many people believe that what you see on Facebook represents some kind of data-mined objective truth unmolested by the subjective attitudes of fair-and-balanced human beings.
  • ...11 more annotations...
  • None of that is true. This week, Facebook rushed to deny a report in Gizmodo that said the team in charge of its “trending” news list routinely suppressed conservative points of view. Last month, Gizmodo also reported that Facebook employees asked Mark Zuckerberg, the social network’s chief executive, if the company had a responsibility to “help prevent President Trump in 2017.” Facebook denied it would ever try to manipulate elections.
  • Even if you believe that Facebook isn’t monkeying with the trending list or actively trying to swing the vote, the reports serve as timely reminders of the ever-increasing potential dangers of Facebook’s hold on the news.
  • The question isn’t whether Facebook has outsize power to shape the world — of course it does, and of course you should worry about that power. If it wanted to, Facebook could try to sway elections, favor certain policies, or just make you feel a certain way about the world, as it once proved it could do in an experiment devised to measure how emotions spread online.
  • There is no evidence Facebook is doing anything so alarming now. The danger is nevertheless real. The biggest worry is that Facebook doesn’t seem to recognize its own power, and doesn’t think of itself as a news organization with a well-developed sense of institutional ethics and responsibility, or even a potential for bias. Neither does its audience, which might believe that Facebook is immune to bias because it is run by computers.
  • That myth should die. It’s true that beyond the Trending box, most of the stories Facebook presents to you are selected by its algorithms, but those algorithms are as infused with bias as any other human editorial decision.
  • “With Facebook, humans are never not involved. Humans are in every step of the process — in terms of what we’re clicking on, who’s shifting the algorithms behind the scenes, what kind of user testing is being done, and the initial training data provided by humans.”Everything you see on Facebook is therefore the product of these people’s expertise and considered judgment, as well as their conscious and unconscious biases apart from possible malfeasance or potential corruption. It’s often hard to know which, because Facebook’s editorial sensibilities are secret. So are its personalities: Most of the engineers, designers and others who decide what people see on Facebook will remain forever unknown to its audience.
  • Facebook also has an unmistakable corporate ethos and point of view. The company is staffed mostly by wealthy coastal Americans who tend to support Democrats, and it is wholly controlled by a young billionaire who has expressed policy preferences that many people find objectionable.
  • You could argue that none of this is unusual. Many large media outlets are powerful, somewhat opaque, operated for profit, and controlled by wealthy people who aren’t shy about their policy agendas — Bloomberg News, The Washington Post, Fox News and The New York Times, to name a few.But there are some reasons to be even more wary of Facebook’s bias. One is institutional. Many mainstream outlets have a rigorous set of rules and norms about what’s acceptable and what’s not in the news business.
  • Those algorithms could have profound implications for society. For instance, one persistent worry about algorithmic-selected news is that it might reinforce people’s previously held points of view. If News Feed shows news that we’re each likely to Like, it could trap us into echo chambers and contribute to rising political polarization. In a study last year, Facebook’s scientists asserted the echo chamber effect was muted.
  • are Facebook’s engineering decisions subject to ethical review? Nobody knows.
  • The other reason to be wary of Facebook’s bias has to do with sheer size. Ms. Caplan notes that when studying bias in traditional media, scholars try to make comparisons across different news outlets. To determine if The Times is ignoring a certain story unfairly, look at competitors like The Washington Post and The Wall Street Journal. If those outlets are covering a story and The Times isn’t, there could be something amiss about the Times’s news judgment.Such comparative studies are nearly impossible for Facebook. Facebook is personalized, in that what you see on your News Feed is different from what I see on mine, so the only entity in a position to look for systemic bias across all of Facebook is Facebook itself. Even if you could determine the spread of stories across all of Facebook’s readers, what would you compare it to?

A News Organization That Rejects the View From Nowhere - Conor Friedersdorf - The Atlantic - 1 views

  • For many years, Rosen has been a leading critic of what he calls The View From Nowhere, or the conceit that journalists bring no prior commitments to their work. On his long-running blog, PressThink, he's advocated for "The View From Somewhere"—an effort by journalists to be transparent about their priors, whether ideological or otherwise.  Rosen is just one of several voices who'll shape NewCo. Still, the new venture may well be a practical test of his View from Somewhere theory of journalism. I chatted with Rosen about some questions he'll face. 
  • The View from Nowhere won’t be a requirement for our journalists. Nor will a single ideology prevail. NewCo itself will have a view of the world: Accountability journalism, exposing abuses of power, revealing injustices will no doubt be part of it. Under that banner many “views from somewhere” can fit.
  • The way "objectivity" evolves historically is out of something much more defensible and interesting, which is in that phrase "Of No Party or Clique." That's the founders of The Atlantic saying they want to be independent of party politics. They don't claim to have no politics, do they? They simply say: We're not the voice of an existing faction or coalition. But they're also not the Voice of God.
  • ...10 more annotations...
  • NewCo will emulate the founders of The Atlantic. At some point "independent from" turned into "objective about." That was the wrong turn, made long ago, by professional journalism, American-style.
  • You've written that The View From Nowhere is, in part, a defense mechanism against charges of bias originating in partisan politics. If you won't be invoking it, what will your defense be when those charges happen? There are two answers to that. 1) We told you where we're coming from. 2) High standards of verification. You need both.
  • What about ideological diversity? The View from Somewhere obviously permits it. You've said you'll have it. Is that because it is valuable in itself?
  • The basic insight is correct: Since "news judgment" is judgment, the product is improved when there are multiple perspectives at the table ... But, if the people who are recruited to the newsroom because they add perspectives that might otherwise be overlooked are also taught that they should leave their politics at the door, or think like professional journalists rather than representatives or their community, or privilege something called "news values" over the priorities they had when they decided to become journalists, then these people are being given a fatally mixed message, if you see what I mean. They are valued for the perspective they bring, and then told that they should transcend that perspective.
  • When people talk about objectivity in journalism they have many different things in mind. Some of these I have no quarrel with. You could even say I’m a “fan.” For example, if objectivity means trying to ground truth claims in verifiable facts, I am definitely for that. If it means there’s a “hard” reality out there that exists beyond any of our descriptions of it, sign me up. If objectivity is the requirement to acknowledge what is, regardless of whether we want it to be that way, then I want journalists who can be objective in that sense. Don’t you? If it means trying to see things in that fuller perspective Thomas Nagel talked about–pulling the camera back, revealing our previous position as only one of many–I second the motion. If it means the struggle to get beyond the limited perspective that our experience and upbringing afford us… yeah, we need more of that, not less. I think there is value in acts of description that do not attempt to say whether the thing described is good or bad. Is that objectivity? If so, I’m all for it, and I do that myself sometimes. 
  • By "we can do better than that" I mean: We can insist on the struggle to tell it like it is without also insisting on the View from Nowhere. The two are not connected. It was a mistake to think that they necessarily are. But why was this mistake made? To control people in the newsroom from "above." That's a big part of objectivity. Not truth. Control.
  • If it works out as you hope, if things are implemented well, etc., what's the potential payoff for readers? I think it's three things: First, this is a news site that is born into the digital world, but doesn't have to return profits to investors. That's not totally unique
  • Second: It's going to be a technology company as much as a news organization. That should result in better service.
  • a good formula for innovation is to start with something people want to do and eliminate some of the steps required to do it
  • The third upside is news with a human voice restored to it. This is the great lesson that blogging gives to journalism

How Do You Know When Society Is About to Fall Apart? - The New York Times - 1 views

  • Tainter seemed calm. He walked me through the arguments of the book that made his reputation, “The Collapse of Complex Societies,” which has for years been the seminal text in the study of societal collapse, an academic subdiscipline that arguably was born with its publication in 1988
  • It is only a mild overstatement to suggest that before Tainter, collapse was simply not a thing.
  • His own research has moved on; these days, he focuses on “sustainability.”
  • ...53 more annotations...
  • He writes with disarming composure about the factors that have led to the disintegration of empires and the abandonment of cities and about the mechanism that, in his view, makes it nearly certain that all states that rise will one day fall
  • societal collapse and its associated terms — “fragility” and “resilience,” “risk” and “sustainability” — have become the objects of extensive scholarly inquiry and infrastructure.
  • Princeton has a research program in Global Systemic Risk, Cambridge a Center for the Study of Existential Risk
  • even Tainter, for all his caution and reserve, was willing to allow that contemporary society has built-in vulnerabilities that could allow things to go very badly indeed — probably not right now, maybe not for a few decades still, but possibly sooner. In fact, he worried, it could begin before the year was over.
  • Plato, in “The Republic,” compared cities to animals and plants, subject to growth and senescence like any living thing. The metaphor would hold: In the early 20th century, the German historian Oswald Spengler proposed that all cultures have souls, vital essences that begin falling into decay the moment they adopt the trappings of civilization.
  • that theory, which became the heart of “The Collapse of Complex Societies.” Tainter’s argument rests on two proposals. The first is that human societies develop complexity, i.e. specialized roles and the institutional structures that coordinate them, in order to solve problems
  • All history since then has been “characterized by a seemingly inexorable trend toward higher levels of complexity, specialization and sociopolitical control.”
  • Eventually, societies we would recognize as similar to our own would emerge, “large, heterogeneous, internally differentiated, class structured, controlled societies in which the resources that sustain life are not equally available to all.”
  • Something more than the threat of violence would be necessary to hold them together, a delicate balance of symbolic and material benefits that Tainter calls “legitimacy,” the maintenance of which would itself require ever more complex structures, which would become ever less flexible, and more vulnerable, the more they piled up.
  • Social complexity, he argues, is inevitably subject to diminishing marginal returns. It costs more and more, in other words, while producing smaller and smaller profits.
  • Take Rome, which, in Tainter's telling, was able to win significant wealth by sacking its neighbors but was thereafter required to maintain an ever larger and more expensive military just to keep the imperial machine from stalling — until it couldn’t anymore.
  • This is how it goes. As the benefits of ever-increasing complexity — the loot shipped home by the Roman armies or the gentler agricultural symbiosis of the San Juan Basin — begin to dwindle, Tainter writes, societies “become vulnerable to collapse.”
  • haven’t countless societies weathered military defeats, invasions, even occupations and lengthy civil wars, or rebuilt themselves after earthquakes, floods and famines?
  • Only complexity, Tainter argues, provides an explanation that applies in every instance of collapse.
  • Complexity builds and builds, usually incrementally, without anyone noticing how brittle it has all become. Then some little push arrives, and the society begins to fracture.
  • A disaster — even a severe one like a deadly pandemic, mass social unrest or a rapidly changing climate — can, in Tainter’s view, never be enough by itself to cause collapse
  • The only precedent Tainter could think of, in which pandemic coincided with mass social unrest, was the Black Death of the 14th century. That crisis reduced the population of Europe by as much as 60 percent.
  • Whether any existing society is close to collapsing depends on where it falls on the curve of diminishing returns.
  • The United States hardly feels like a confident empire on the rise these days. But how far along are we?
  • Scholars of collapse tend to fall into two loose camps. The first, dominated by Tainter, looks for grand narratives and one-size-fits-all explanations
  • The second is more interested in the particulars of the societies they study
  • Patricia McAnany, who teaches at the University of North Carolina at Chapel Hill, has questioned the usefulness of the very concept of collapse — she was an editor of a 2010 volume titled “Questioning Collapse” — but admits to being “very, very worried” about the lack, in the United States, of the “nimbleness” that crises require of governments.
  • We’re too vested and tied to places.” Without the possibility of dispersal, or of real structural change to more equitably distribute resources, “at some point the whole thing blows. It has to.”
  • In Turchin’s case the key is the loss of “social resilience,” a society’s ability to cooperate and act collectively for common goals. By that measure, Turchin judges that the United States was collapsing well before Covid-19 hit. For the last 40 years, he argues, the population has been growing poorer and more unhealthy as elites accumulate more and more wealth and institutional legitimacy founders. “The United States is basically eating itself from the inside out,
  • Inequality and “popular immiseration” have left the country extremely vulnerable to external shocks like the pandemic, and to internal triggers like the killings of George Floyd
  • Societies evolve complexity, he argues, precisely to meet such challenges.
  • Eric H. Cline, who teaches at the George Washington University, argued in “1177 B.C.: The Year Civilization Collapsed” that Late Bronze Age societies across Europe and western Asia crumbled under a concatenation of stresses, including natural disasters — earthquakes and drought — famine, political strife, mass migration and the closure of trade routes. On their own, none of those factors would have been capable of causing such widespread disintegration, but together they formed a “perfect storm” capable of toppling multiple societies all at once.
  • Collapse “really is a matter of when,” he told me, “and I’m concerned that this may be the time.”
  • In “The Collapse of Complex Societies,” Tainter makes a point that echoes the concern that Patricia McAnany raised. “The world today is full,” Tainter writes. Complex societies occupy every inhabitable region of the planet. There is no escaping. This also means, he writes, that collapse, “if and when it comes again, will this time be global.” Our fates are interlinked. “No longer can any individual nation collapse. World civilization will disintegrate as a whole.”
  • If it happens, he says, it would be “the worst catastrophe in history.”
  • The quest for efficiency, he wrote recently, has brought on unprecedented levels of complexity: “an elaborate global system of production, shipping, manufacturing and retailing” in which goods are manufactured in one part of the world to meet immediate demands in another, and delivered only when they’re needed. The system’s speed is dizzying, but so are its vulnerabilities.
  • A more comprehensive failure of fragile supply chains could mean that fuel, food and other essentials would no longer flow to cities. “There would be billions of deaths within a very short period,” Tainter says.
  • If we sink “into a severe recession or a depression,” Tainter says, “then it will probably cascade. It will simply reinforce itself.”
  • Tainter tells me, he has seen “a definite uptick” in calls from journalists: The study of societal collapse suddenly no longer seems like a purely academic pursuit
  • Turchin is keenly aware of the essential instability of even the sturdiest-seeming systems. “Very severe events, while not terribly likely, are quite possible,” he says. When he emigrated from the U.S.S.R. in 1977, he adds, no one imagined the country would splinter into its constituent parts. “But it did.”
  • He writes of visions of “bloated bureaucracies” becoming the basis of “entire political careers.” Arms races, he observes, presented a “classic example” of spiraling complexity that provides “no tangible benefit for much of the population” and “usually no competitive advantage” either.
  • It is hard not to read the book through the lens of the last 40 years of American history, as a prediction of how the country might deteriorate if resources continued to be slashed from nearly every sector but the military, prisons and police.
  • The more a population is squeezed, Tainter warns, the larger the share that “must be allocated to legitimization or coercion.
  • And so it was: As U.S. military spending skyrocketed — to, by some estimates, a total of more than $1 trillion today from $138 billion in 1980 — the government would try both tactics, ingratiating itself with the wealthy by cutting taxes while dismantling public-assistance programs and incarcerating the poor in ever-greater numbers.
  • “As resources committed to benefits decline,” Tainter wrote in 1988, “resources committed to control must increase.”
  • The overall picture drawn by Tainter’s work is a tragic one. It is our very creativity, our extraordinary ability as a species to organize ourselves to solve problems collectively, that leads us into a trap from which there is no escaping
  • Complexity is “insidious,” in Tainter’s words. “It grows by small steps, each of which seems reasonable at the time.” And then the world starts to fall apart, and you wonder how you got there.
  • Perhaps collapse is not, actually, a thing. Perhaps, as an idea, it was a product of its time, a Cold War hangover that has outlived its usefulness, or an academic ripple effect of climate-change anxiety, or a feedback loop produced by some combination of the two
  • if you pay attention to people’s lived experience, and not just to the abstractions imposed by a highly fragmented archaeological record, a different kind of picture emerges.
  • Tainter’s understanding of societies as problem-solving entities can obscure as much as it reveals
  • Plantation slavery arose in order to solve a problem faced by the white landowning class: The production of agricultural commodities like sugar and cotton requires a great deal of backbreaking labor. That problem, however, has nothing to do with the problems of the people they enslaved. Which of them counts as “society”?
  • Since the beginning of the pandemic, the total net worth of America’s billionaires, all 686 of them, has jumped by close to a trillion dollars.
  • If societies are not in fact unitary, problem-solving entities but heaving contradictions and sites of constant struggle, then their existence is not an all-or-nothing game.
  • Collapse appears not as an ending, but a reality that some have already suffered — in the hold of a slave ship, say, or on a long, forced march from their ancestral lands to reservations faraway — and survived.
  • The current pandemic has already given many of us a taste of what happens when a society fails to meet the challenges that face it, when the factions that rule over it tend solely to their own problems
  • the real danger comes from imagining that we can keep living the way we always have, and that the past is any more stable than the present.
  • If you close your eyes and open them again, the periodic disintegrations that punctuate our history — all those crumbling ruins — begin to fade, and something else comes into focus: wiliness, stubbornness and, perhaps the strongest and most essential human trait, adaptability.
  • When one system fails, we build another. We struggle to do things differently, and we push on. As always, we have no other choice.

Natural Sciences - Theory of Knowledge - 0 views

  •  The natural sciences reflect a concerted effort on the part of humans to search for understanding of the world. Like any other human endeavour, the development of scientific knowledge forms a web with more practical, even everyday, interests and concerns. The natural sciences are recognized as a model for knowledge owing to many factors, prime among which is their capacity to explain and make precise predictions
  • If natural sciences are defined as investigating the natural world, what is meant by “natural” or “nature” in this context? What difference might it make to scientific work if nature were to be regarded as a machine (for example, as a clockwork mechanism) or as an organism (such as in some interpretations of the Gaia hypothesis)? How useful are these metaphors?Does scientific language and vocabulary have primarily a descriptive or an interpretative function? Consider here expressions such as “artificial intelligence”, “electric current”, “natural selection” and “concentration gradient”.

Knowledge and Language - TOK 2022: THEORY OF KNOWLEDGE WEBSITE FOR THE IBDP - 0 views

  • Language is a medium through which we pass on most knowledge. You could ask yourself how much you would know if you had no language to gather or express knowledge. Our daily language is heavily influenced by the discourse of the most dominant groups in our communities, even though we may not always be aware of this fact. The language we speak can be used to pass on knowledge and values that exist within our community, but it also influences to some extent how we know. Even though the limitations of the Sapir-Whorf Hypothesis's linguistic determinism have been pointed out, new research (eg by Boroditsky, see below) reveals how the language we speak may shape the way we think

Sense Perception Notes - ToK - 0 views

  • "Perception by the senses rather than by the intellect." (Dictionary.com)
  • "Perception by or based on stimulation of the senses." (Medical Dictionary)
  • We perceive the world through our five senses. (Hearing, Sight, Smell, Touch, Taste) Our sense receptors are stimulated by sensory information. The brain translates the sensory information into sensations such as sound, taste, temperature, etc. Higher centres in the brain either ignore or recognize the sensations and their meanings, based on neuronal networks of past association and expectation. (Some of this stage 3 work actually involves reasoning).  Click the video to see a coffee-taste expert discuss the intricacies of how different coffees taste.    Sense perception is an important dimension of comprehending the world around us. It allows us to gather information from the outside world, so we can then go on to hopefully make sense of it

  • Stimuli are involuntarily being compared and contrasted with previous experiences. For example, when you see when you see stop light change from red to green, your mind perceives this change in colour, not so much as a change in colour, but more as a signal to move forward.
  • What we perceive depends on what is important and interest in at the time for each person (Cultural Influences on Perception). Our perceptions and conceptions are affected by things such as biases, motivations emotions cultural perspectives interests, expectations and background experiences (existing knowledge)
  • Optical illusions are very popular with students just starting out in ToK. They are clear evidence that we have weaknesses in terms of how our mind interprets stimuli. Often things are not as they appear. Our previous experiences with similar stimulai impairs our perception.

Republicans Wonder How, And If, They Can Pull The Party Back Together : NPR - 0 views

  • In a matter of hours on Jan. 6, the Republican Party went from shrugging off its loss of the White House to a party in crisis.
  • making President Trump the first president since Herbert Hoover whose party lost the White House, the House and the Senate in one term.
  • Now, Trump leaves office as the only president to be impeached twice, and the House vote against Trump over the Capitol insurrection marked the most bipartisan impeachment in U.S. history.

  • I don't know how you bring these people together.
  • "This isn't their Republican Party anymore," the president's son said. "This is Donald Trump's Republican Party."
  • He thinks the big divide is between authoritarians and those who believe in democracy.
  • It's a fundamental belief in whether or not you want to continue the American experiment.
  • You have a segment of American society that does not accept the election outcome and is going to continue to speak up, is going to continue to agitate. And that's going to make this a very unstable period for months and perhaps even years."
  • That means a long, unstable period not just for the Republican Party, but for the American political system as a whole.
  • Annie says it wasn't that long ago that she could talk politics with her mom without things getting heated. But when the pandemic started, she says their conversations were peppered with conspiracies.
  • And what I found were stories, mostly from family members of people who have gotten wrapped up in political conspiracy theories like QAnon. And many are adult children who say they can't really have a civil conversation with their parents anymore and that it wasn't always this way.
  • It kind of seems normal at first. And then all of a sudden, something will just be out of the blue that just seems so far from anything that could be true.
  • UNIDENTIFIED PERSON: She's spending 16 to 18 hours a day consuming this. CORNISH: And the result of all this is a detachment from the facts.
  • Q's stories range from false notions about COVID to a cabal running the U.S. government to the claim there's a secret world of satanic pedophiles. But what's relevant here is that this culminates in a belief that President Trump is a kind of savior figure, which leads to the next phase for these families - a breakdown.
  • Because these belief systems are not about the information within them, but about the identity and the emotions that are appealed to through them, the only thing that can actually combat them effectively are loving, trusting, emotional connections.
  • Do not mock. Do not use snark. All of the, you know, Twitter posts where people make fun of the crazy QAnon supporters, all that does is further reinforce their sense that they are disrespected and maligned.
  • No. 2 - using scientific evidence, argumentation, etc., that comes through the very institutions that they have been told not to trust, that is going to backfire because now they think that you are the dupe because you trust these institutions, etc.

For Black Americans, The White Terror In D.C. Looks Familiar | HuffPost - 0 views

  • This was the case for pro-Trump rioters in 2021. It was also the case for white supremacists in Wilmington, North Carolina, in 1898, in America’s first and only successful coup d’etat.
  • His refusal to accept the results of a fair and free election, as well as his spread of lies and conspiracy theories about election fraud, emboldened his base to besiege the U.S. Capitol building, riot on its steps, fire bullets in its halls and terrorize elected officials.
  • Nooses, unambiguous symbols of mob mentality and racial terror against Black Americans, were strung up on the Capitol grounds to remind everyone exactly what the rioters stood for — and who they stood against.
  • ...8 more annotations...
  • Many saw this coming. The rioters had been planning in plain sight. But perhaps Black Americans were the least surprised by the day’s events. The precedent had been set, time and again. We don’t have to look back that far for reminders: Whether in 1900, or 1925, or 1939, or 1965, or 2020, white terror has been deeply embedded in American culture, especially in the face of Black progress and the quest for freedom and equality.
  • For more than a century, Black Americans have documented and warned us of similar moments where racial terror and white supremacy were the status quo.
  • Less than a year later, at the height of the KKK’s popularity, 30,000 members descended upon Washington, and were welcomed by the city.
  • The whites, once again, had free rein to terrorize.
  • Civil rights activists, including the late John Lewis, set off to peacefully march across the Edmund Pettus Bridge to advocate for equal voting rights. Lewis, then 25, was beaten by Alabama state troopers and his skull was fractured. Activist Amelia Boynton Robinson was knocked unconscious. They were tear-gassed. 
  • And then there are too many instances to list from the last six years of the Black Lives Matter movement. At protest after protest against police brutality, Black activists were met with state-sanctioned violence at the hands of police.

How Galileo Galilei's discoveries helped create modern science - 0 views

  • Few people in history can claim as large a contribution to how we conduct and think about science as Galileo. His work revolutionized our entire outlook on what it means to study nature (and got him in some very hot water with the Roman Inquisition)
  • He is perhaps best known for his championing of Copernicus’ heliocentric model (the one that says the Earth and other planets orbit the Sun), but that is by no means the full extent of his legacy. Far, far from it.
  • Galileo earned himself a place among the stars as Europe’s global navigation satellite system bears his name
  • ...10 more annotations...
  • Galileo is certainly among the titans of science — in many ways, he’s one of its ‘founders’. His legacy includes contributions to the fields of physics, astronomy, math, engineering, and the application of the scientific method
  • He was an accomplished mathematician and inventor, designing (among others) several military compasses and the thermoscope. He was also the one to pick up the torch of modern astronomy from Copernicus, cementing the foundations of this field of study by proving his theories right.
  • Showing others what science can do, and how one should go about it, is Galileo’s most important achievement. Its effects still ripple through the lives of every researcher to this day
  • Since the days of Aristotle, scholars in Europe believed that heavier objects fall faster than lighter ones. Galileo showed that this wasn’t the case, using balls of the same materials but different weights and sizes. In one of his infamous experiments, he dropped two such balls from the top of the leaning tower of Pisa to show that objects of different weights accelerate just as fast towards the ground (air resistance notwithstanding).
  • The truth is Galileo’s experiments in this area used a more reliable but less flashy bunch of inclined planes that he rolled balls down on.
  • His interest regarding motion and the falling of objects were tightly linked to Galileo’s interest in planets, stars, and the solar system.
  • Apart from his theoretical pursuits, Galileo was also an accomplished engineer — meaning he could also turn his knowledge to the solving of practical problems. Most of these, historical accounts tell us, were attempts by Galileo to earn a little bit of extra cash in order to support his extended family after his father passed away.
  • Among his creations are a set of military compasses (sectors) that were simple enough for artillery crews and surveyors to use.
  • He was also an early builder and user of telescopes and microscopes. Galileo, among a few select others, was the first to ever use a refracting telescope as an instrument to observe heavenly bodies, in 1609
  • His fascination with celestial bodies and defense of the heliocentric model is what eventually led to the Inquisition cracking down on him and his works.

8 Things You May Not Know About Galileo - HISTORY - 0 views

  • When he was 16, Galileo enrolled at the University of Pisa to study medicine, at his father’s urging. Instead, though, he became interested in mathematics and shifted his focus to that subjec
  • Galileo left the school in 1585 without earning a degree.
  • Galileo didn’t invent the telescope—Dutch eyeglass maker Hans Lippershey is generally credited with its creation—but he was the first person to use the optical instrument to systematically study the heavens.

  • In 1609, Galileo learned about the device and developed one of his own, significantly improving its design. That fall, he pointed it at the moon and discovered it had craters and mountains, debunking the common belief that the moon’s surface was smooth.
  • Galileo soon went on to make other findings with his telescope, including that there were four moons orbiting Jupiter and that Venus went through a complete set of phases (indicating the planet traveled around the sun).
  • Galileo had three children with a woman named Marina Gamba, who he never married. In 1613, he placed his two daughters, Virginia, born in 1600, and Livia, born in 1601, in a convent near Florence, where they remained for the rest of their lives, despite their father’s eventual troubles with the Catholic Church
  • Copernicus’ heliocentric theory about the way the universe works challenged the widely accepted belief, espoused by the astronomer Ptolemy in the second century, that put the Earth at the center of the solar system.
  • Galileo received permission from the Church to continue investigating Copernicus’ ideas, as long as he didn’t hold or defend them.
  • As a result, the following year Galileo was ordered to stand trial before the Inquisition in Rome
  • After being found guilty of heresy, Galileo was forced to publicly repent and sentenced to life in prison.
  • Although Galileo was given life behind bars, his sentence soon was changed to house arrest. He lived out his final years at Villa Il Gioiello (“the Jewel”), his home in the town of Arcetri, near Florence
  • In 1979, Pope John Paul II initiated an investigation into the Catholic Church’s condemnation of Galileo.
  • Thirteen years later, and 359 years after Galileo was tried by the Inquisition, the pope officially closed the investigation and issued a formal apology in the case, acknowledging that errors were made by the judges during the trial.

The Problem of Perception (Stanford Encyclopedia of Philosophy) - 0 views

  • Sense-perception has long been a preoccupation of philosophers. One pervasive and traditional problem, sometimes called “the Problem of Perception”, is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perception be what we ordinarily understand it to be, an openness to and awareness of the world? The present entry is about how these possibilities of error challenge the intelligibility of the phenomenon of perception, and how the major theories of experience in the last century are best understood as responses to this challenge.
  • According to Awareness, we are sometimes perceptually aware of ordinary mind-independent objects in perceptual experience. Such awareness can come from veridical experiences—cases in which one perceives an object for what it is. But it can also come from illusory experiences. For we think of an illusion as “any perceptual situation in which a physical object is actually perceived, but in which that object perceptually appears other than it really is” Smith (2002: 23). For example, a white wall seen in yellow light can look yellow to one. (In such cases it is not necessary that one is deceived into believing that things are other than they are). The argument from illusion, in a radical form, aims to show that we are never perceptually aware of ordinary objects. Many things have been called “the argument from illusion”

Natural Sciences - TOK 2022: THEORY OF KNOWLEDGE WEBSITE FOR THE IBDP - 1 views

  • Each discipline within the natural sciences aims to produce knowledge about different aspects of the natural world. In this sense, each discipline within the natural sciences will tweak its methodology somewhat to fit its particular purpose and scope. Nevertheless, all disciplines within the natural sciences will broadly have a shared underlying scope, methodology and purpose.
  • You arguably trusted your teachers and believed that what they told you in science class was true. But under which circumstances should we accept second hand scientific knowledge? The motto of Britain's very first scientific society  (The Royal Society)  is "Nullius in Verba", which means "Take nobody's word for it".  One of the key features of the natural sciences is the necessity of being able to prove what you claim. Good science does not only require proof. It also actively invites peer-review and even falsification. For example, if your teacher claims that starch will turn blue when mixed with iodine, you will want to test this yourself. Within the natural sciences, you should be able to repeat experiments to see if a hypothesis is correct. But what should you conclude when an experiment 'does not work'? If this happens in you science lesson, you may have made a mistake.

Memory Notes - ToK - 0 views

  • "We can invent only with memory." (Alphonse Karr) “Memory and imagination help [a man] as he works. Not only his own thoughts, but the thoughts of the men of past ages guide his hands; and, as a part of the human race, he creates.” (William Morris) “Memory feeds imagination.” (Amy Tan) “Memory is imagination in reverse.” (Stephen Evans) "Memory is deceptive because it is coloured by today’s events."

Pfizer and Moderna Vaccines Likely to Produce Lasting Immunity, Study Finds - The New Y... - 0 views

  • in people who survived Covid-19, immune cells that recognize the virus lie quiescent in the bone marrow for at least eight months after infection. A study by another team indicated that so-called memory B cells continue to mature and strengthen for at least a year after infection.
  • Based on those findings, researchers suggested that immunity might last for years, possibly a lifetime, in people who were infected with the coronavirus and later vaccinated.
  • But it was unclear whether vaccination alone might have a similarly long-lasting effect.
  • ...13 more annotations...
  • “Usually by four to six weeks, there’s not much left,” said Deepta Bhattacharya, an immunologist at the University of Arizona. But germinal centers stimulated by the mRNA vaccines are “still going, months into it, and not a lot of decline in most people.”
  • The broader the range and the longer these cells have to practice, the more likely they are to be able to thwart variants of the virus that may emerge.
  • “Everyone always focuses on the virus evolving — this is showing that the B cells are doing the same thing,” said Marion Pepper, an immunologist at the University of Washington in Seattle. “And it’s going to be protective against ongoing evolution of the virus, which is really encouraging.”
  • Dr. Ellebedy’s team found that 15 weeks after the first dose of vaccine, the germinal center was still highly active in all 14 of the participants, and that the number of memory cells that recognized the coronavirus had not declined.
  • “The fact that the reactions continued for almost four months after vaccination — that’s a very, very good sign,” Dr. Ellebedy said. Germinal centers typically peak one to two weeks after immunization, and then wane.
  • After an infection or a vaccination, a specialized structure called the germinal center forms in lymph nodes. This structure is an elite school of sorts for B cells — a boot camp where they become increasingly sophisticated and learn to recognize a diverse set of viral genetic sequences.
  • The results suggest that a vast majority of vaccinated people will be protected over the long term — at least, against the existing coronavirus variants
  • But older adults, people with weak immune systems and those who take drugs that suppress immunity may need boosters; people who survived Covid-19 and were later immunized may never need them at all.
  • In the absence of variants that sidestep immunity, in theory immunity could last a lifetime, experts said. But the virus is clearly evolving.
  • “Anything that would actually require a booster would be variant-based, not based on waning of immunity,” Dr. Bhattacharya said. “I just don’t see that happening.”
  • The good news: A booster vaccine will probably have the same effect as prior infection in immunized people, Dr. Ellebedy said. “If you give them another chance to engage, they will have a massive response,” he said, referring to memory B cells.
  • Dr. Ellebedy said the results also suggested that these signs of persistent immune reaction might be caused by mRNA vaccines alone, as opposed to those made by more traditional means, like Johnson & Johnson’s
  • But that is an unfair comparison, because the Johnson & Johnson vaccine is given as a single dose, Dr. Iwasaki said: “If the J & J had a booster, maybe it will induce this same kind of response.”
