A Nasty New World « The Dish - 0 views

  • Bernard Bailyn The Barbarous Years, which details the “little-remembered” brutality of life in the American colonies during the 17th century:
  • Bailyn has not painted a pretty picture. Little wonder he calls it The Barbarous Years and spares us no details of the terror, desperation, degradation and widespread torture—do you really know what being “flayed alive” means?

  • It’s a grand drama in which the glimmers of enlightenment barely survive the savagery, what Yeats called “the blood-dimmed tide,” the brutal establishment of slavery, the race wars with the original inhabitants that Bailyn is not afraid to call “genocidal,” the full, horrifying details of which have virtually been erased.

Pigeon Code Baffles British Cryptographers - NYTimes.com - 0 views

Why Not Just Weigh the Fish? - NYTimes.com - 0 views

  • The essence of philosophy is abstract reasoning – not because the philosopher is too lazy to attempt a more hands-on approach, but because the subjects at issue do not readily submit to it. If we could simply weigh the fish, we gladly would. In recent centuries, philosophers in fact have discovered how to weigh that allegorical fish, in various fields, and on each occasion a new discipline has been born: physics in the 17th century; chemistry in the 18th; biology in the 19th and psychology in the 20th.
  • The remaining problems of philosophy today concern issues like justice, morality, free will, knowledge and the origins of the universe. In dismissing philosophy as an antiquated relic of our prescientific past, the scientist is making a very large and dubious assumption: that the abstract methods of philosophy, despite the discipline’s string of successes over recent centuries, have nothing more to contribute to our developing understanding of the world
  • Philosophy today continues to rest, albeit somewhat precariously, at the center of human inquiry, continuous at one end with the sciences to which it gave rise, and at the other end with history and literature. Professional philosophers tend to crowd around the scientific end of that spectrum, busily looking for new ways to weigh their fish. But much of what gives philosophy its continuing fascination is its connection with the humanities. To weigh the fish is doubtless desirable, but there is just as much to be learned in understanding where that fish came from, and in telling stories about where it might go.

Evolution and the American Myth of the Individual - NYTimes.com - 0 views

  • the country’s two main political parties have “fundamental philosophical differences.” But what exactly does that mean?
  • In a broad sense, Democrats, particularly the more liberal among them, are more likely to embrace the communal nature of individual lives and to strive for policies that emphasize that understanding.
  • Republicans, especially libertarians and Tea Party members on the ideological fringe, however, often trace their ideas about freedom and liberty back to Enlightenment thinkers of the 17th and 18th centuries, who argued that the individual is the true measure of human value, and each of us is naturally entitled to act in our own best interests free of interference by others. Self-described libertarians generally also pride themselves on their high valuation of logic and reasoning over emotion.

  • Philosophers from Aristotle to Hegel have emphasized that human beings are essentially social creatures, that the idea of an isolated individual is a misleading abstraction. So it is not just ironic but instructive that modern evolutionary research, anthropology, cognitive psychology and neuroscience have come down on the side of the philosophers who have argued that the basic unit of human social life is not and never has been the selfish, self-serving individual.
  • The irony here is that when it comes to our responsibilities to one another as human beings, religion and evolution nowadays are not necessarily on opposite sides of the fence.
  • in the eyes of many conservative Americans today, religion and evolution do not mix. You either accept what the Bible tells us or what Charles Darwin wrote, but not both
  • Contrary to libertarian and Tea Party rhetoric, evolution has made us a powerfully social species, so much so that the essential precondition of human survival is and always has been the individual plus his or her relationships with others.
  • as Matthew D. Lieberman, a social neuroscience researcher at the University of California, Los Angeles, has written: “we think people are built to maximize their own pleasure and minimize their own pain. In reality, we are actually built to overcome our own pleasure and increase our own pain in the service of following society’s norms.”
  • Why then did Rousseau and others make up stories about human history if they didn’t really believe them? The simple answer, at least during the Enlightenment, was that they wanted people to accept their claim that civilized life is based on social conventions, or contracts, drawn up at least figuratively speaking by free, sane and equal human beings — contracts that could and should be extended to cover the moral and working relationships that ought to pertain between rulers and the ruled.
  • Jean-Jacques Rousseau famously declared in “The Social Contract” (1762) that each of us is born free and yet everywhere we are in chains. He did not mean physical chains. He meant social ones. We now know he was dead wrong. Human evolution has made us obligate social creatures. Even if some of us may choose sooner or later to disappear into the woods or sit on a mountaintop in deep meditation, we humans are able to do so only if before such individualistic anti-social resolve we have first been socially nurtured and socially taught survival arts by others. The distinction Rousseau and others tried to draw between “natural liberty, which is bounded only by the strength of the individual” and “civil liberty, which is limited by the general will” is fanciful, not factual.
  • In short, their aims were political, not historical, scientific or religious.
  • what Rousseau and others crafted as arguments in favor of their ideas all had the earmarks of primitive mythology
  • Bronislaw Malinowski argued almost a century ago: “Myth fulfills in primitive culture an indispensable function: it expresses, enhances, and codifies belief, it safeguards and enforces morality, it vouches for the efficiency of ritual and contains practical rules for the guidance of man.”
  • not all myths make good charters for faith and wisdom. The sanctification of the rights of individuals and their liberties today by libertarians and Tea Party conservatives is contrary to our evolved human nature as social animals. There was never a time in history before civil society when we were each totally free to do whatever we elected to do. We have always been social and caring creatures. The thought that it is both rational and natural for each of us to care only for ourselves, our own preservation, and our own achievements is a treacherous fabrication. This is not how we got to be the kind of species we are today.
  • Myths achieve this social function, he observed, by serving as guides, or charters, for moral values, social order and magical belief.
  • Nor is this what the world’s religions would ask us to believe.

Not that some country named Christiania exists in the heart of Denmark, but that they can legitimately call themselves a nation. We have grown up, and our parents have grown up, with a rigid definition of nationalism, and the strange notion that the lines in an atlas were always there. One interpretation of the Danish government's response to Christiania is simply that they do not know what to think. Although probably not geopolitically significant, such enclave states represent a challenge our perception of countries, one which fascinates Middleton's readers because it disconcerts them.

Opinion | Michael Hayden: The End of Intelligence - The New York Times - 0 views

  • To adopt post-truth thinking is to depart from Enlightenment ideas, dominant in the West since the 17th century, that value experience and expertise, the centrality of fact, humility in the face of complexity, the need for study and a respect for ideas.
  • the Trump campaign normalized lying to an unprecedented degree.
  • When pressed on specifics, the president has routinely denigrated those who questioned him, whether the “fake” media, “so called” judges, Washington insiders or the “deep state.” He has also condemned Obama-era intelligence officials as “political hacks.”

  • you could sometimes convince a liar that he was wrong. What do you do with someone who does not distinguish between truth and untruth?
  • How the erosion of Enlightenment values threatens good intelligence was obvious in the Trump administration’s ill-conceived and poorly carried out executive order that looked to the world like a Muslim ban.
  • They didn’t seem very interested in facts, either. Or at least not in my facts. Political partisanship in America has become what David Brooks calls “totalistic.” Partisan identity, as he writes, fills “the void left when their other attachments wither away — religious, ethnic, communal and familial.” Beliefs are now so tied to these identities that data is not particularly useful to argue a point.
  • Intelligence work — at least as practiced in the Western liberal tradition — reflects these threatened Enlightenment values: gathering, evaluating and analyzing information, and then disseminating conclusions for use, study or refutation.
  • we have never served a president for whom ground truth really doesn’t matter.
  • The president by all accounts is not a patient man. According to The Washington Post, one Trump confidant called him “the two-minute man” with “patience for a half page.”
  • Over time it has become clear to me that security decisions in the Trump administration follow a certain pattern. Discussion seems to start with a presidential statement or tweet. Then follows a large-scale effort to inform the president, to impress upon him the complexity of an issue, to review the relevant history, to surface more factors bearing on the problem, to raise second- and third-order consequences and to explore subsequent moves.
  • He insists on five-page or shorter intelligence briefs, rather than the 60 pages we typically gave previous presidents. There is something inherently disturbing in that. There are some problems that cannot be simplified.
  • Intelligence becomes a feeble academic exercise if it is not relevant and useful
  • History — and the next president — will judge American intelligence, and if it is found to have been too accommodating to this or any other president, it will be disastrous for the community.
  • These are truly uncharted waters for the country. We have in the past argued over the values to be applied to objective reality, or occasionally over what constituted objective reality, but never the existence or relevance of objective reality itself.
  • In this post-truth world, intelligence agencies are in the bunker with some unlikely mates: journalism, academia, the courts, law enforcement and science — all of which, like intelligence gathering, are evidence-based.
  • Intelligence shares a broader duty with these other truth-tellers to preserve the commitment and ability of our society to base important decisions on our best judgment of what constitutes objective reality.
  • The historian Timothy Snyder stresses the importance of reality and truth in his cautionary pamphlet, “On Tyranny.” “To abandon facts,” he writes, “is to abandon freedom. If nothing is true, then no one can criticize power because there is no basis upon which to do so.” He then chillingly observes, “Post-truth is pre-fascism.”

Is our world a simulation? Why some scientists say it's more likely than not | Technolo... - 3 views

  • Musk is just one of the people in Silicon Valley to take a keen interest in the “simulation hypothesis”, which argues that what we experience as reality is actually a giant computer simulation created by a more sophisticated intelligence
  • Oxford University’s Nick Bostrom in 2003 (although the idea dates back as far as the 17th-century philosopher René Descartes). In a paper titled “Are You Living In a Simulation?”, Bostrom suggested that members of an advanced “posthuman” civilization with vast computing power might choose to run simulations of their ancestors in the universe.
  • If we believe that there is nothing supernatural about what causes consciousness and it’s merely the product of a very complex architecture in the human brain, we’ll be able to reproduce it. “Soon there will be nothing technical standing in the way to making machines that have their own consciousness,
  • ...14 more annotations...
  • At the same time, videogames are becoming more and more sophisticated and in the future we’ll be able to have simulations of conscious entities inside them.
  • “Forty years ago we had Pong – two rectangles and a dot. That’s where we were. Now 40 years later, we have photorealistic, 3D simulations with millions of people playing simultaneously and it’s getting better every year. And soon we’ll have virtual reality, we’ll have augmented reality,” said Musk. “If you assume any rate of improvement at all, then the games will become indistinguishable from reality.”
  • “If one progresses at the current rate of technology a few decades into the future, very quickly we will be a society where there are artificial entities living in simulations that are much more abundant than human beings.
  • If there are many more simulated minds than organic ones, then the chances of us being among the real minds starts to look more and more unlikely. As Terrile puts it: “If in the future there are more digital people living in simulated environments than there are today, then what is to say we are not part of that already?”
  • Reasons to believe that the universe is a simulation include the fact that it behaves mathematically and is broken up into pieces (subatomic particles) like a pixelated video game. “Even things that we think of as continuous – time, energy, space, volume – all have a finite limit to their size. If that’s the case, then our universe is both computable and finite. Those properties allow the universe to be simulated,” Terrile said
  • “Is it logically possible that we are in a simulation? Yes. Are we probably in a simulation? I would say no,” said Max Tegmark, a professor of physics at MIT.
  • “In order to make the argument in the first place, we need to know what the fundamental laws of physics are where the simulations are being made. And if we are in a simulation then we have no clue what the laws of physics are. What I teach at MIT would be the simulated laws of physics,”
  • Terrile believes that recognizing that we are probably living in a simulation is as game-changing as Copernicus realizing that the Earth was not the center of the universe. “It was such a profound idea that it wasn’t even thought of as an assumption,”
  • That we might be in a simulation is, Terrile argues, a simpler explanation for our existence than the idea that we are the first generation to rise up from primordial ooze and evolve into molecules, biology and eventually intelligence and self-awareness. The simulation hypothesis also accounts for peculiarities in quantum mechanics, particularly the measurement problem, whereby things only become defined when they are observed.
  • “For decades it’s been a problem. Scientists have bent over backwards to eliminate the idea that we need a conscious observer. Maybe the real solution is you do need a conscious entity like a conscious player of a video game,
  • How can the hypothesis be put to the test
  • scientists can look for hallmarks of simulation. “Suppose someone is simulating our universe – it would be very tempting to cut corners in ways that makes the simulation cheaper to run. You could look for evidence of that in an experiment,” said Tegmark
  • First, it provides a scientific basis for some kind of afterlife or larger domain of reality above our world. “You don’t need a miracle, faith or anything special to believe it. It comes naturally out of the laws of physics,”
  • it means we will soon have the same ability to create our own simulations. “We will have the power of mind and matter to be able to create whatever we want and occupy those worlds.”

The Facebooking of Economics - NYTimes.com - 2 views

  • there has been a major erosion of the old norms. It used to be the case that to have a role in the economics discourse you had to have formal credentials and a position of authority; you had to be a tenured professor at a top school publishing in top journals, or a senior government official.

  • you don’t get to play a major role in that discourse by publishing clever Slateish snark; you get there by saying smart things backed by data.

America Is Flunking Math - Persuasion - 1 views

  • One can argue that the preeminence of each civilization was, in part, due to their sophisticated understanding and use of mathematics. This is particularly clear in the case of the West, which forged ahead in the 17th century with the discovery of calculus, one of the greatest scientific breakthroughs of all time.
  • The United States became the dominant force in the mathematical sciences in the wake of World War II, largely due to the disastrous genocidal policies of the Third Reich. The Nazis’ obsession with purging German science of what it viewed as nefarious Jewish influence led to a massive exodus of Jewish mathematicians and scientists to America
  • Indeed, academic institutions in the United States have thrived largely because of their ability to attract talented individuals from around the world.
  • ...28 more annotations...
  • The quality of mathematics research in the United States today is the envy of the scientific world. This is a direct result of the openness and inclusivity of the profession.
  • Can Americans maintain this unmatched excellence in the future? There are worrisome signs that suggest not.
  • The Organization for Economic Cooperation and Development compares mathematical proficiency among 15-year-olds by country worldwide. According to its 2018 report, America ranked 37th while China, America’s main competitor for world leadership, came in first.
  • This is despite the fact that the United States is the fifth-highest spender per pupil among the 37 developed OECD nations
  • This massive failure of our K-12 education system trickles through the STEM pipeline.
  • At the undergraduate level, too few American students are prepared for higher-level mathematics courses. These students are then unprepared for rigorous graduate-level work
  • According to our own experiences at the universities where we teach, an overwhelming majority of American students with strong math backgrounds are either foreign-born or first-generation students who have additional support from their education-conscious families. At all levels, STEM disciplines are more and more dependent on a constant flow of foreign talent.
  • There are many reasons for this failure, but the way that we educate and prepare teachers is particularly influential. The vast majority of K-12 math teachers are graduates of teacher-preparation programs that teach very little substantive mathematics
  • This has led to a constant stream of ill-advised and dumbed-down reforms. One of the latest fads is anti-racist mathematics. Promoted in several states, the bizarre doctrine threatens to further degrade the teaching of mathematics.
  • Another major concern is the twisted interpretation of diversity, equity, and inclusion (DEI).
  • Under the banner of DEI, universities are abandoning the use of standardized tests like the SAT and GRE in admissions, and cities are considering scrapping academic tracking and various gifted programs in schools, which they deem “inequitable.”
  • such programs are particularly effective, when properly implemented, at discovering and encouraging talented children from disadvantaged backgrounds.
  • The new 2021 Mathematics Framework, currently under consideration by California’s Department of Education, does away “with all tracking, acceleration, gifted programs, or any instruction that involves clustering by individual differences, without expressing any awareness of the impact these drastic alterations would have in preparing STEM-ready candidates.”
  • These measures will not only hinder the progress of the generations of our future STEM workforce but also contribute to structural inequalities, as they are uniquely detrimental to students whose parents cannot send them to private schools or effective enrichment programs.
  • These are just a few examples of an unprecedented fervor for revolutionary change in the name of Critical Race Theory (CRT), a doctrine that views the world as a fierce battleground for the narratives of various identity groups.
  • This will only lead to a further widening of racial disparities in educational outcomes while lowering American children’s rankings in education internationally.
  • Ill-conceived DEI policies, often informed by CRT, and the declining standards of K-12 math education feed each other in a vicious circle
  • Regarding minorities, in particular, public K-12 education all too often produces students unprepared to compete, thus leading to large disparities in admissions at universities, graduate programs, and faculty positions. This disparity is then condemned as a manifestation of structural racism, resulting in administrative measures to lower the evaluation criteria. Lowering standards at all levels leads eventually to even worse outcomes and larger disparities, and so on in a downward spiral.
  • A case in point is the recent report by the American Mathematical Society that accuses the entire mathematics community, with the thinnest of specific evidence, of systemic racial discrimination. A major justification put forward for such a grave accusation is the lack of sufficient representation of Black mathematicians in the professio
  • the report, while raising awareness of several ugly facts from the long-ago past, makes little effort to address the real reasons for this, mainly the catastrophic failure of the K-12 mathematical educational system.
  • The National Science Foundation, a federal institution meant to support fundamental research, is now diverting some of its limited funding to various DEI initiatives of questionable benefit.
  • Meanwhile, other countries, especially China, are doing precisely the opposite, following the model of our past dedication to objective measures of excellence. How long before we will see a reverse exodus, away from the United States?
  • The present crisis can still be reversed by focusing on a few concrete actions:
  • Improve schools in urban areas and inner-city neighborhoods by following the most promising education programs. These programs demonstrate that inner-city children benefit if they are challenged by high standards and a nurturing environment.
  • Follow the lead of other highly successful rigorous programs such as BASIS schools and Math for America, which focus on rigorous STEM curricula, combined with 21st-century teaching methods, and recruit talented teachers to help them build on their STEM knowledge and teaching methods.
  • Increase, rather than eliminate, tailored instruction, both for accelerated and remedial math courses.
  • Reject the soft bigotry of low expectations, that Black children cannot do well in competitive mathematics programs and need dumbed-down ethnocentric versions of mathematics.
  • Uphold the objective selection process based on merit at all levels of education and research.

Copernicus, Galileo, and the Church: Science in a Religious World - Inquiries Journal - 0 views

  • During most of the 16th and 17th centuries, fear of heretics spreading teachings and opinions that contradicted the Bible dominated the Catholic Church
  • A type of war between science and religion was in play but there would be more casualties on the side of science.
  • Nicholas Copernicus and Galileo Galilei were two scientists who printed books that later became banned
  • ...8 more annotations...
  • Copernicus faced no persecution when he was alive because he died shortly after publishing his book. Galileo, on the other hand, was tried by the Inquisition after his book was published
  • As the contents of the Bible were taken literally, the publishing of these books proved, to the Church, that Copernicus and Galileo were sinners; they preached, through their writing, that the Bible was wrong.
  • By writing in this fashion, Copernicus would have been able to deny that he himself believed in heliocentrism because he phrased it as nothing more than a hypothesis and as a result, would be able to slip past the Church's dislike of heliocentrism
  • fter his death, the Church was heavily involved in the Council of Trent during the years 1545 to 1563 and other matters10.) . Thus, Revolutions escaped prohibition for many years and eventually influenced Galileo Galilei, who read it and wrote on the subject himself
  • In 1616, Galileo was issued an injunction not to “hold, defend, or teach” heliocentrism
  • The Master of the Sacred Palace ordered Galileo to have someone the Master chose review the manuscript to ensure it was fit for publishing.
  • Also, the title with the sea in it might have made the Church feel threatened that Galileo was supporting heliocentrism, which would have resulted in Galileo being charged with heresy.
  • With that decision, it was determined that Galileo would be tried by the Inquisition. The Inquisition did not need to decide if Galileo was innocent or guilty, they already knew he was guilty. The Inquisition wanted to determine what Galileo's intentions were. Galileo tried to delay going to Rome for the trial, most likely due to the Inquisition's infamous methods.

Ron DeSantis' Florida boast rings hollow (opinion) - CNN - 0 views

  • New cases of Covid-19 in the United States have fallen in the last two months to about 55,000 a day.
  • These numbers are promising, but the ups and downs and ups tell an important lesson about keeping perspective in a pandemic. Today's promising numbers would have been horrific at this time last year and are hardly as good as they need to be.
  • No one knows this more than the country's governors. Since the Trump White House dumped the job of handling the pandemic almost entirely into their laps, they have had to respond on the fly.
  • ...10 more annotations...
  • We are already seeing the first wave of "who won and who lost" sorts of stories pitting various governors' responses against each other in horse-race fashion, as if these were early polls for the 2024 presidential election.
  • Then reality stepped in. A surge of summer cases forced the imposition of some restrictions on Floridians, like local mask mandates imposed by mayors in some cities in South Florida.
  • Now DeSantis is claiming again to be a master of pandemic control, as Florida's beach-tourism-restaurant industry is said to be doing well. Never mind that the state's seven-day infection rate of 143.9 per 100,000 population places it 12th highest of the 50 states.
  • For example, as of March 22, over the last seven days, Florida has had the most Covid-19 cases in the country, according to data from the US Centers for Disease Control and Prevention (CDC), the 12th highest per capita case-rate, the fourth highest number of deaths, and the 17th highest death rate.
  • Once celebrated for his pandemic management, he is now getting poor marks on managing. He has not strutted or had roundtables of fan-doctors to sing his praise. But the fact is California's recent numbers are much better than those of Florida, coming in at about 47th in the country with a case-rate 46.8 per 100,000, according to the CDC's data, and fewer deaths as well.
  • Florida is ignoring the death toll and instead pushing the upbeat metrics the governor would like America to pay attention to: jobs are up! and schools are open! DeSantis stood up to the Covid-19 threat like John Wayne would have done!

  • These rate-the-governors perspectives ignore a basic fact: it is no time for trophies.
  • Worse, this obeisance to economic and social factors as measure of success creates a series of disturbing false equivalencies as they compare deaths against the economy.
  • Measuring Covid-19 management on anything other than the number of human lives lost is not only disgraceful, it will also almost certainly lead us to make all the wrong decisions once again and usher in yet another Covid-19 resurgence in the US.

How Isaac Newton Changed the World | Live Science - 0 views

  • To the probable dismay of some befuddled calculus and physics students the world over, Isaac Newton didn't just live, he grew up and lived long enough to become the single-most influential scientist of the 17th-century.
  • Newton's wide range of discoveries, from his theories of optics to his groundbreaking work on the laws of motion and gravity, formed the basis for modern physics.
  • The true genius of his work, experts think, is how he ultimately took those theories and applied them to the universe at large, explaining the motions of the Sun and planets in a way that had never been done before.

  • Upon getting bumped on the head by a falling apple, Newton airily dreams up the laws of gravity and the rest, as they say, is history
  • When the black plague closed Cambridge University, where he was a student, for two years starting in 1665, he spent the long months locked up at home studying complex mathematics, physics and optics.
  • It was during this fruitful time that Newton, with the help of a crystal prism, became the first to discover that white light is made up a spectrum of colors
  • He also developed the concept of infinite-series calculus, the kind of scary math studied today by engineering and statistics scholars.
  • By 1666, Newton had even laid the blueprints for his three laws of motion, still recited by physics students everywhere:An object will remain in a state of inertia unless acted upon by force.The relationship between acceleration and applied force is F=ma.For every action there is an equal and opposite reaction.
  • Across the pages of the Principia, Newton breaks down the workings of the solar system into "'simple"' equations, explaining away the nature of planetary orbits and the pull between heavenly bodies.

Linguistic Relativity: the Impact of Language & Society | THE ELLIPSIS... - 0 views

  • As English speakers, we experience life in English. Our every thought is formulated with the English terminology available to us. But how might our experience and our thinking be different if our primary language was not English but German or Arabic?
  • It is this very question that has motivated linguists for hundreds of years to grapple with the validity of linguistic relativity
  • When we consider the theory of linguistic relativity, we must take into account that languages develop within and emerge from distinct cultures
  • ...14 more annotations...
  • Those who subscribe to the theory of linguistic relativity believe that a person’s way of thinking is influenced by the language he or she speaks
  • Language is a result of society. Therefore, language does not deserve the credit for shaping the way we process information.
  • Differences in the thought processes of speakers of different languages should be accredited to the distinct cultures from which these languages emerge.
  • Nevertheless, language is an important factor in the way a culture evolves. Ultimately, although it is our society rather than our language that shapes the way we think, language helps to enforce the way society is.
  • Language cannot be said to be responsible for the way a society functions since language itself is a result of that society. A key example of this can be found in the substance of a language, which tends to reflect the values of its speakers and the culture it comes from
  • A proponent of linguistic relativity might argue that this is an example of language shaping the way people think by defining age as the primary quality to know about a person.
  • However, this assertion fails to recognize the big picture. A more accurate analysis might indicate that society is responsible for this way of thinking, not language.
  • However, language still plays an important role in affecting cultures and social norms. Although languages are reflections of cultures, languages do influence how cultures will look in the future.
  • We can see this phenomenon in the history of the English language, which dates back to sometime between the 5th and 7th century AD, with Modern English gaining prominence in the late 17th century.
  • As we see with English sentence structure, the influence of cultural institutions on a language is often left intact even after that institution has weakened or disappeared.
  • Since language is our only proficient method of communication, what we can communicate is limited to the words and phrases available to us. While the society we live in may limit our perspective, the extent and strength of these limitations do not compare to that which language imposes. Cultural change comes more easily to us than linguistic change.
  • t took centuries for the Great Vowel Shift to occur while the world experienced revolutions, literary movements, great awakenings and deadly plagues at a much faster pace. This pattern is demonstrated in American culture as the language we speak fails to keep up with the progress we make. Patterns in our vocabulary tend to reflect this.
  • A commonly cited phenomenon is the negative and positive associations that English seems to make with “black” and “white.”
  • The limits of language may prevent us from progressing as quickly as we may want to, but we do have the ability to overcome some of these linguistic limits.

Did an apple really fall on Isaac Newton's head? - HISTORY - 0 views

  • Legend has it that a young Isaac Newton was sitting under an apple tree when he was bonked on the head by a falling piece of fruit, a 17th-century “aha moment” that prompted him to suddenly come up with his law of gravity. In reality, things didn’t go down quite like that.
  • Four years later, following an outbreak of the bubonic plague, the school temporarily closed, forcing Newton to move back to his childhood home, Woolsthorpe Manor
  • It was during this period at Woolsthorpe (Newton returned to Cambridge in 1667) that he was in the orchard there and witnessed an apple drop from a tree.
  • ...4 more annotations...
  • There’s no evidence to suggest the fruit actually landed on his head, but Newton’s observation caused him to ponder why apples always fall straight to the ground (rather than sideways or upward) and helped inspired him to eventually develop his law of universal gravitation
  • In 1687, Newton first published this principle, which states that every body in the universe is attracted to every other body with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them, in his landmark work the “Principia,” which also features his three laws of motion.
  • In 1726, Newton shared the apple anecdote with William Stukeley, who included it in a biography, “Memoirs of Sir Isaac Newton’s Life,” published in 1752.
  • His famous apple tree continues to grow at Woolsthorpe Manor.

The History of Dice Reflects Beliefs in Fate and Chance - The Atlantic - 0 views

  • Dice, in their standard six-sided form, seem like the simplest kind of device—almost a classic embodiment of chance. But a new study of more than 100 examples from the last 2,000 years or so unearthed in the Netherlands shows that they have not always looked exactly the way they do now. What’s more, the shifts in dice’s appearance may reflect people’s changing sense of what exactly is behind a roll—fate, or probability.
  • Did it matter to game players that these dice were not fair? “We don’t know for sure,” Eerkens says. The way Romans wrote about dice falls suggests they were regarded as signs of supernatural favor or of a player’s fortune, however. The archaeologist Ellen Swift, in her book Roman Artifacts and Society, writes that high rolls had associations of benevolence and felicity, and that rolling three sixes at the same time seems to have been called a Venus. “Dice potentially played an important role in conceptualizing divine action in the world,” she writes.
  • At the same time, dice tend to get smaller, perhaps to make them easier to hide, as gambling was not favored by the increasingly powerful religious authorities. Some of the study’s dice from this era, in fact, were found all together in a small hole in a garbage heap, including one cheater’s die with an extra three. Could it be someone saw the light and forswore dice?

  • . In the 17th century, even Galileo writes about why, in a game with three dice, the number 10 should come up more than the number 9. It’s an observation that one would only be able to detect after thousands of rolls, but the reason behind it involves how many combinations of numbers can add up to each different option.
  • All these changes in dice come about, says Eerkens, “as different astronomers are coming up with new ideas about the world, and mathematicians are starting to understand numbers and probability.” Which came first: Did people begin to intuitively understand what true chance felt like, and adjusted dice accordingly, or did it trickle out from what would eventually become known as the scientific community?
  • And it does make you wonder: Would you know that fair dice should fall equally on each side, or that in a three-dice game, it’s better to bet on 10 than nine, if someone hadn’t told you?

How can Boris Johnson run the UK while suffering from coronavirus? - CNN - 0 views

  • When British Prime Minister Boris Johnson announced on Friday morning that he had tested positive for coronavirus, he insisted that he would continue to head up his country's fight against the pandemic.
  • Isolating the Prime Minister is not that difficult, in itself. The Downing Street premises are actually considerably bigger than they look from the outside. Behind that famous black door at Number 10 lies a warren of rooms and offices that extend sideways into 11 and 12 Downing Street -- the three addresses are all that survive from a longer terrace constructed at the end of the 17th century -- and back into a much larger 18th-century building at the rear.
  • Meetings will take place via video conference. While this might sound unusual, some of Johnson's most important regular appointments had already stopped being personal interactions.
  • ...1 more annotation...
  • Inside 10 Downing Street itself, considered a place of work more than a place of residence, the roughly 250-strong teams of civil servants and political advisers has been stripped back to only essential workers, with approximately 70 people on site at any given time. Johnson's official spokesperson said that inside No 10, staff had been "observing the advice on social distancing" and using video conferencing wherever possible.

The best country in the world to raise a child? It's not America, survey finds - CNN - 0 views

  • What's the best country in the world to raise a child? If a well developed public education system tops your list, you'd likely consider the United States -- it took the top spot in education in this year's Best Countries Report, done annually since 2016 by U.S. News & World Report and the Wharton School of the University of Pennsylvania.
  • "One area where the US falls behind quite a bit is in the safety metric," she said. "In that attribute, the US actually ranks 32, pretty far down the list. So that really impacts its ratings for raising kids, of course." Read MoreCanada came in fourth for raising kids, followed by the Netherlands, Finland, Switzerland, New Zealand, Australia and Austria. The UK came in at number 11.
  • The Best Countries report evaluated 73 nations across 65 different metrics. To do so it surveyed more than 20,000 people in the Americas, Asia, Europe, the Middle East and Africa. Respondents are rather evenly split between leaders in business; college-educated citizens who consider themselves middle class or higher and who read or watch the news at least four days a week; and the general public, defined as over age 18 who's age and gender were nationally representative of their countries' demographic.

  • "United States is no longer trustworthy. It's 50% less less trustworthy than it was when we first started a survey back in 2016," said McPhillips.
  • The US also came in at number 15 in citizenship, quality of life and best place to visit. It ranked 17th in greenest countries, 18th in most transparent countries, and 26th in best places to travel alone -- another safety issue.

Shaking Off Outmoded Ideas On Race | Duke Today - 0 views

  • “Race as we thought of it in the 17th and 18th centuries is wrong,” he said. “Yet in high school and college texts, race is still taught as if it were real.” -- Joseph Graves
  • “That message has never gotten to the American public,” said Graves, who noted he is the first African-American to hold a tenured position in the field of evolutionary biology.
  • “People are conflating ancestry with race, and they’re not equivalent,” said Duke geneticist and bioethicist Charmaine Royal.
