The philosopher Immanuel Kant (1724–1804) argued in his Critique of Pure Reason that the human mind knows objects in innate, a priori ways. Kant claimed that humans, from birth, must experience all objects as being successive (time) and juxtaposed (space). His list of inborn categories describes predicates that the mind can attribute to any object in general. Arthur Schopenhauer (1788–1860) agreed with Kant, but reduced the number of innate categories to one—causality—which presupposes the others.

Modern nativism is most associated with the work of Jerry Fodor (1935–2017), Noam Chomsky (b. 1928), and Steven Pinker (b. 1954), who argue that humans from birth have certain cognitive modules (specialised genetically inherited psychological abilities) that allow them to learn and acquire certain skills, such as language.

For example, children demonstrate a facility for acquiring spoken language but require intensive training to learn to read and write. This poverty of the stimulus observation became a principal component of Chomsky's argument for a "language organ"—a genetically inherited neurological module that confers a somewhat universal understanding of syntax that all neurologically healthy humans are born with, which is fine-tuned by an individual's experience with their native language

In The Blank Slate (2002), Pinker similarly cites the linguistic capabilities of children, relative to the amount of direct instruction they receive, as evidence that humans have an inborn facility for speech acquisition (but not for literacy acquisition).

A number of other theorists[1][2][3] have disagreed with these claims. Instead, they have outlined alternative theories of how modularization might emerge over the course of development, as a result of a system gradually refining and fine-tuning its responses to environmental stimuli.[4]

Many empiricists are now also trying to apply modern learning models and techniques to the question of language acquisition, with marked success.[20] Similarity-based generalization marks another avenue of recent research, which suggests that children may be able to rapidly learn how to use new words by generalizing about the usage of similar words that they already know (see also the distributional hypothesis).[14][21][22][23]

The term universal grammar (or UG) is used for the purported innate biological properties of the human brain, whatever exactly they turn out to be, that are responsible for children's successful acquisition of a native language during the first few years of life. The person most strongly associated with the hypothesising of UG is Noam Chomsky, although the idea of Universal Grammar has clear historical antecedents at least as far back as the 1300s, in the form of the Speculative Grammar of Thomas of Erfurt.

This evidence is all the more impressive when one considers that most children do not receive reliable corrections for grammatical errors.[9] Indeed, even children who for medical reasons cannot produce speech, and therefore have no possibility of producing an error in the first place, have been found to master both the lexicon and the grammar of their community's language perfectly.[10] The fact that children succeed at language acquisition even when their linguistic input is severely impoverished, as it is when no corrective feedback is available, is related to the argument from the poverty of the stimulus, and is another claim for a central role of UG in child language acquisition.

Researchers at Blue Brain discovered a network of about fifty neurons which they believed were building blocks of more complex knowledge but contained basic innate knowledge that could be combined in different more complex ways to give way to acquired knowledge, like memory.[11

experience, the tests would bring about very different characteristics for each rat. However, the rats all displayed similar characteristics which suggest that their neuronal circuits must have been established previously to their experiences. The Blue Brain Project research suggests that some of the "building blocks" of knowledge are genetic and present at birth.[11]

modern nativist theory makes little in the way of specific falsifiable and testable predictions, and has been compared by some empiricists to a pseudoscience or nefarious brand of "psychological creationism". As influential psychologist Henry L. Roediger III remarked that "Chomsky was and is a rationalist; he had no uses for experimental analyses or data of any sort that pertained to language, and even experimental psycholinguistics was and is of little interest to him".[13]

, Chomsky's poverty of the stimulus argument is controversial within linguistics.[14][15][16][17][18][19]

Neither the five-year-old nor the adults in the community can easily articulate the principles of the grammar they are following. Experimental evidence shows that infants come equipped with presuppositions that allow them to acquire the rules of their language.[6]

Paul Griffiths, in "What is Innateness?", argues that innateness is too confusing a concept to be fruitfully employed as it confuses "empirically dissociated" concepts. In a previous paper, Griffiths argued that innateness specifically confuses these three distinct biological concepts: developmental fixity, species nature, and intended outcome. Developmental fixity refers to how insensitive a trait is to environmental input, species nature reflects what it is to be an organism of a certain kind, and the intended outcome is how an organism is meant to develop.[24]

hose promises have also fueled anxiety over how people will be able to compete for jobs outsourced to eerily refined machines or trust the accuracy of what they see online.

Officials with the San Francisco lab said GPT-4’s “multimodal” training across text and images would allow it to escape the chat box and more fully emulate a world of color and imagery, surpassing ChatGPT in its “advanced reasoning capabilities.”

A person could upload an image and GPT-4 could caption it for them, describing the objects and scene.

AI language models often confidently offer wrong answers because they are designed to spit out cogent phrases, not actual facts. And because they have been trained on internet text and imagery, they have also learned to emulate human biases of race, gender, religion and class.

GPT-4 still makes many of the errors of previous versions, including “hallucinating” nonsense, perpetuating social biases and offering bad advice. It also lacks knowledge of events that happened after about September 2021, when its training data was finalized, and “does not learn from its experience,” limiting people’s ability to teach it new things.

Microsoft has invested billions of dollars in OpenAI in the hope its technology will become a secret weapon for its workplace software, search engine and other online ambitions. It has marketed the technology as a super-efficient companion that can handle mindless work and free people for creative pursuits, helping one software developer to do the work of an entire team or allowing a mom-and-pop shop to design a professional advertising campaign without outside help.

it could lead to business models and creative ventures no one can predict.

sparked criticism that the companies are rushing to exploit an untested, unregulated and unpredictable technology that could deceive people, undermine artists’ work and lead to real-world harm.

the company held back the feature to better understand potential risks. As one example, she said, the model might be able to look at an image of a big group of people and offer up known information about them, including their identities — a possible facial recognition use case that could be used for mass surveillance.

OpenAI researchers wrote, “As GPT-4 and AI systems like it are adopted more widely,” they “will have even greater potential to reinforce entire ideologies, worldviews, truths and untruths, and to cement them or lock them in.”

“We can agree as a society broadly on some harms that a model should not contribute to,” such as building a nuclear bomb or generating child sexual abuse material, she said. “But many harms are nuanced and primarily affect marginalized groups,” she added, and those harmful biases, especially across other languages, “cannot be a secondary consideration in performance.”

OpenAI said its new model would be able to handle more than 25,000 words of text, a leap forward that could facilitate longer conversations and allow for the searching and analysis of long documents.

OpenAI developers said GPT-4 was more likely to provide factual responses and less likely to refuse harmless requests

Duolingo, the language learning app, has already used GPT-4 to introduce new features, such as an AI conversation partner and a tool that tells users why an answer was incorrect.

The company did not share evaluations around bias that have become increasingly common after pressure from AI ethicists.

GPT-4 will have competition in the growing field of multisensory AI. DeepMind, an AI firm owned by Google’s parent company Alphabet, last year released a “generalist” model named Gato that can describe images and play video games. And Google this month released a multimodal system, PaLM-E, that folded AI vision and language expertise into a one-armed robot on wheels: If someone told it to go fetch some chips, for instance, it could comprehend the request, wheel over to a drawer and choose the right bag.

The systems, though — as critics and the AI researchers are quick to point out — are merely repeating patterns and associations found in their training data without a clear understanding of what it’s saying or when it’s wrong.

GPT-4, the fourth “generative pre-trained transformer” since OpenAI’s first release in 2018, relies on a breakthrough neural-network technique in 2017 known as the transformer that rapidly advanced how AI systems can analyze patterns in human speech and imagery.

The systems are “pre-trained” by analyzing trillions of words and images taken from across the internet: news articles, restaurant reviews and message-board arguments; memes, family photos and works of art.

Giant supercomputer clusters of graphics processing chips are mapped out their statistical patterns — learning which words tended to follow each other in phrases, for instance — so that the AI can mimic those patterns, automatically crafting long passages of text or detailed images, one word or pixel at a time.

In 2019, the company refused to publicly release GPT-2, saying it was so good they were concerned about the “malicious applications” of its use, from automated spam avalanches to mass impersonation and disinformation campaigns.

Altman has also marketed OpenAI’s vision with the aura of science fiction come to life. In a blog post last month, he said the company was planning for ways to ensure that “all of humanity” benefits from “artificial general intelligence,” or AGI — an industry term for the still-fantastical idea of an AI superintelligence that is generally as smart as, or smarter than, the humans themselves.

very early ages we [in America] see struggle as an indicator that you're just not very smart," Stigler says. "It's a sign of low ability — people who are smart don't struggle, they just naturally get it, that's our folk theory. Whereas in Asian cultures they tend to see struggle more as an opportunity."

For the most part in American culture, intellectual struggle in schoolchildren is seen as an indicator of weakness, while in Eastern cultures it is not only tolerated, it is often used to measure emotional strength.

to understand why these two cultures view struggle so differently, it's good to step back and examine how they think about where academic excellence comes from.

American mother is communicating to her son that the cause of his success in school is his intelligence. He's smart — which, Li says, is a common American view.

children are not creative. Our children do not have individuality. They're just robots. You hear the educators from Asian countries express that concern, a

"So the focus is on the process of persisting through it despite the challenges, not giving up, and that's what leads to success," Li says.

Obviously if struggle indicates weakness — a lack of intelligence — it makes you feel bad, and so you're less likely to put up with it. But if struggle indicates strength — an ability to face down the challenges that inevitably occur when you are trying to learn something — you're more willing to accept it.

American students "worked on it less than 30 seconds on average and then they basically looked at us and said, 'We haven't had this,'" he says.

Japanese students worked for the entire hour on the impossible problem.

Westerns tend to worry that their kids won't be able to compete against Asian kids who excel in many areas but especially in math and science. Jin Li says that educators from Asian countries have their own set of worries.

"The idea of intelligence in believed in the West as a cause," Li explains. "She is telling him that there is something in him, in his mind, that enables him to do what he does."

in the Japanese classrooms that he's studied, teachers consciously design tasks that are slightly beyond the capabilities of the students they teach, so the students can actually experience struggling with something just outside their reach. Then, once the task is mastered, the teachers actively point out that the student was able to accomplish it through the students hard work and struggle.

When Google’s algorithm detects a search term for which this distilled information is available, the search engine is trained to go fetch it rather than merely present links to Web pages. “There has been a shift in our thinking,” said Scott Huffman, an engineering director in charge of search quality at Google. “A part of our resources are now more human curated.”

“Our engineers evolve the algorithm, and humans help us see if a suggested change is really an improvement,” Mr. Huffman said.

The history of Europe since the 18th century has been the story of successive attempts to find alternatives to God as an object of worship, among them the nation state, race and the Communist Manifesto. After this cost humanity two world wars, a Cold War and a hundred million lives, we have turned to more pacific forms of idolatry, among them the market, the liberal democratic state and the consumer society,

This is what a society built on materialism, individualism and moral relativism looks like. It maximises personal freedom but at a cost.

This freedom, energising and exciting as it is, is also profoundly disintegrative, making it very difficult for individuals to find any stable communal support, very difficult for any community to count on the responsible participation of its individual members. It opens solitary men and women to the impact of a lowest common denominator, commercial culture.’

In one respect the new atheists are right. The threat to western freedom in the 21st century is not from fascism or communism but from a religious fundamentalism combining hatred of the other, the pursuit of power and contempt for human rights.

But the idea that this can be defeated by individualism and relativism is naive almost beyond belief. Humanity has been here before.

The barbarians win. They always do.

The new barbarians are the fundamentalists who seek to impose a single truth on a plural world. Though many of them claim to be religious, they are actually devotees of the will to power. Defeating them will take the strongest possible defence of freedom, and strong societies are always moral societies

That does not mean that they need be religious. It is just that, in the words of historian Will Durant, ‘There is no significant example in history, before our time, of a society successfully maintaining moral life without the aid of religion.’

I have not yet found a secular ethic capable of sustaining in the long run a society of strong communities and families on the one hand, altruism, virtue, self-restraint, honour, obligation and trust on the other

A century after a civilisation loses its soul it loses its freedom also. That should concern all of us, believers and non-believers alike.

The effectiveness of this process is so great that human brain is able to accurately identify words and whole phrases from a noisy background. This power of analysis brings to minds the great similarity between the brain and powerful supercomputers.

Functional imaging of the brain revealed that activated brain parts are different between native and non-native speakers. The superior temporal gyrus is an important brain region involved in language learning. For a native speaker this part is responsible for automated processing of lexical retrieval and the build of phrase structure. In native speakers this zone is much more activated than in non-native ones.

infants begin their lives with a very flexible brain that allows them to acquire virtually any language they are exposed to. Moreover, they can learn a language words almost equally by listening or by visual coding. This brain plasticity is the motor drive of the children capability of “cracking the speech code” of a language. With time, this ability is dramatically decreased and adults find it harder to acquire a new language.

clearly demonstrated that there are anatomical brain differences between fast and slow learners of foreign languages. By analyzing a group of people having a homogenous language background, scientists found that differences in specific brain regions can predict the capacity of a person to learn a second language.

Until the last decade few studies compared the language acquisition in adults and children. Thanks to modern imaging and electroencephalography we are now able to address this question.

Language acquisition is a long-term process by which information are stored in the brain unconsciously making them appropriate to oral and written usage. In contrast, language learning is a conscious process of knowledge acquisition that needs supervision and control by the person.

Fifty Republican national-security experts signed an open letter declaring Trump a danger to the republic; several staffers quit the Republican National Committee rather than work to elect Trump. Allegiances have been sundered, and professional trajectories thrown into confusion.

Several Republicans I know, finding the campaign intolerable, have rediscovered old hobbies.

Although he was originally drawn to the party for its emphasis on economic freedom and self-reliance, he now believes that a substantial portion of Republicans were never motivated by those ideas. Rather than a conservative party that happens to incorporate cultural grievances, today’s GOP is, in his view, a vehicle for the racial resentment, nationalism, and nostalgia of older white voters.

Trump is the “logical end point” of the GOP’s long history of racialized politics.

search could be – and was – personalised, because Google’s algorithms could figure out what each user was most likely to be interested in, and therefore what kinds of information would be most relevant for her or him. So, imperceptibly, but inexorably over time, we have come to live in what Eli Pariser christened a “filter bubble”.

Before the internet, our problem with information was its scarcity. Now our problem is unmanageable abundance. So now the scarce resources are attention and time, over which a vicious war has broken out between traditional media and the internet-based upstarts.

YouTube has a billion users, half of whom access it via mobile devices. The average time spent on the site is 40 minutes. Facebook now claims to have 1.65 billion monthly active users, who spend on average 50 minutes a day on its services. So if Google is an 800lb gorilla, Facebook is a megaton King Kong.

Competition for attention and time is a zero-sum game that traditional media are losing. In desperation, they are trying both to appease Facebook and to harness its hold on people’s attention

In doing so, they have entered into a truly Faustian bargain. Because while publishers can without difficulty ship their stuff to Instant Articles, they cannot control which ones Facebook users actually get to see. This is because users’ news feeds are determined by Facebook’s machine-learning algorithms that try to guess what each user would like to see (and what might dispose them to click on an advertisement).

when you ask – as Professor George Brock memorably did – whether Mark Zuckerberg and his satraps understand that they have acquired editorial responsibilities, they look blank. Facebook is not a publisher, they explain, merely a “platform”. And, besides, no humans are involved in curating users’ news feeds: it’s all done by algorithms and is therefore neutral. In other words: nothing to see here; move on.

Any algorithm that has to make choices has criteria that are specified by its designers. And those criteria are expressions of human values. Engineers may think they are “neutral”, but long experience has shown us they are babes in the woods of politics, economics and ideology.

“The adult eye just isn’t capable of that amount of accommodation,” she says.

said it was capable of miniaturizing its nuclear weapons and attaching them to rockets, meaning it would feasibly be able to blast them at all its imperialist pig-dog enemies in the USA—but obviously, these claims haven't yet been verified.

Secondly, we can turn to neuroscience. Until recently we haven’t been able to look under the skull and see what the brain does when a problem is highly complex. The good news? The brain has a secret weapon against complexity, a process neuroscientists are now calling “insight.” We are learning more everyday about insight’s ability to catch the brain up to complexity—the real antidote to reverting to beliefs as a default.

During adolescence, the neurocircuitry strengthens and allows for multitasking, enhanced ability to solve problems, and the capability to process complex information. Furthermore, adolescent brain plasticity provides an opportunity to develop talents and lifelong interests; however, neurotoxic insult, trauma, chronic stress, drug abuse, and sedentary lifestyles may have a negative impact during this sensitive period of brain maturation

Combined with a gift for humor, anger lies at the heart of Trump’s charisma.

“I think the differences are still greater than the similarities,” he says. “Hitler was not only more intelligent, but craftier. He was not just a powerful orator, but a talented actor who succeeded in winning over various social milieus. So not just the economically threatened lower middle classes which Trump targeted, but also the upper middle classes. Hitler had many supporters in the German aristocracy.”

Trump was also democratically elected, while Hitler never had a majority vote. “He was appointed by the president of the German Reich.” Then there’s the fact that Trump does not lead a party “which is unconditionally committed to him”.

“A further obvious difference is that Trump doesn’t have a private militia, as Hitler did with the SA, which he used in his first months after coming to power to settle scores with his opponents, like the Communists and Social Democrats. You can’t possibly imagine something similar with Trump – that he’ll be locking Democrats up into concentration camps

“Finally, the American constitution is based on a system of checks and balances. It remains to be seen how far Congress will really limit Trump or if, as is feared, he can override it. It was different with Hitler, who, as we know, managed to eliminate all resistance in the shortest space of time and effectively establish himself as an all-powerful dictator. Within a few months, there was effectively no longer any opposition.”

“Hitler profited from the fact that his opponents always underestimated him,” Ullrich explains. “His conservative allies in government assumed they could tame or ‘civilise’ him – that once he became chancellor he’d become vernünftig (meaning sensible, reasonable). Very quickly it became clear that was an illusion.”

“There were many situations where he could have been stopped. For example in 1923 after the failed Munich putsch – if he’d served his full prison sentence of several years, he wouldn’t have made a political comeback. Instead, he only spent a few months behind bars, [having been released after political pressure] and could rebuild his movement.”

The western powers made the same mistake with their appeasement politics, indecision and indulgence. “In the 1930s Hitler strengthened, rather than weakened, his aggressive intentions,” Ullrich says. “So you could learn from this that you have to react faster and much more vigorously than was the case at the time.”

llrich also contends that if Hindenburg, the president of the Reich, had allowed Chancellor Brüning, of the Centre party, to remain chancellor to the end of 1934, rather than responding to pressure from conservatives to dismiss him in 1932, “then the peak of the economic crisis would have passed and it would have been very questionable whether Hitler could still have come to power”.

At the same time, Hitler’s ascent was no mere fluke. “There were powerful forces in the big industries, but also in the landowning class and the armed forces, which approved of a fascist solution to the crisis.”

If fascism “now just means aggressive nationalism, racism, patriarchy and authoritarianism, then maybe it is back on the agenda,” Bosworth continues. But today’s context is fundamentally different

Today’s “alt-right” agitators “live in a neoliberal global order where the slogan, ‘all for the market, nothing outside the market, no one against the market’ is far more unquestionably accepted than the old fascist slogan of ‘all for the state, nothing outside the state, no one against the state’”.

“What is that if it’s not racially authoritarian?” asks Schama. “If you want to call it fascist, fine. I don’t really care if it’s called that or not. It’s authoritarian, you know, ferociously authoritarian.”

Schama also points to deeply worrying messaging, such as “the parallel universe of lies which are habitual, massive, cumulative”; the criminalization of political opponents; the threat to change the libel laws against the press and the demonization of different racial and ethnic groups, going as far as proposing a Muslim registry.

Schama is clear: Trump is obviously not Hitler. “But, you know, if you like, he’s an entertainment fascist, which may be less sinister but is actually in the end more dangerous. If you’re not looking for jackboots and swastikas – although swastikas are indeed appearing – there’s a kind of laundry list of things which are truly sinister and authoritarian and not business as usual.”

Don’t ignore what people vote fo

f you’re of German heritage, it’s hard to understand how so many people could have bought Mein Kampf and gone on to vote for Hitler. Maybe no one really read it, or got beyond the first few pages of bluster, or took antisemitism seriously, you tell yourself. “Or they liked what he said,

“I think one of the mistakes this time around would be not to think that the people who voted for Trump were serious. They may have been serious for different reasons, but it would be a big mistake not to try and figure out what their reasons were.

Hitler presented himself as a “messiah” offering the public “salvation”, Ullrich points out. With austerity and hostility to the EU and to immigrants riding high, there is fertile ground for European populists next year to seduce with equally simplistic, sweeping “solutions”.

The problem, in Mazower’s view, is that establishment politicians currently have no response

“The Gestapo was piddling compared with the size and reach of surveillance equipment and operations today,

“Very belatedly, everyone is waking up to the fact that there was a general assumption that no government in the west would fall into the wrong hands, that it was safe to acquiesce in this huge expansion of surveillance capabilities, and the debate wasn’t as vigorous as it could have been.”

“Now, there is a lot of discussion about allowing this kind of surveillance apparatus in the wrong hands,” he adds. “And we’ve woken up to this a bit late in the day.”

Ullrich calls crises, “the elixir of rightwing populists”, and urges that politicians “do everything they can to correct the inequalities and social injustice which have arisen in the course of extreme financial capitalism in western countries”

Jane Caplan, a history professor at Oxford University who has written about Trump and fascism, highlights the want of “dissenting voices against marketisation and neoliberalism

The failure to resist the incursion of the market as the only criterion for political utility, or economic utility, has been pretty comprehensive.

Paranoia, bullying and intimidation are a hallmark of authoritarian regimes. They are also alive and well in our culture today, where online trolls, violent thugs at rallies, threats of expensive libel action and of course terrorist acts are equally effective in getting individuals and the press to self-censor.

He announces his enmity to America by word and action every day. It is articulated in his insistence on the rightness of torture and the acceptable murder of noncombatants. It is self-evident in the threats he makes daily to destroy his political enemies, made only worse by the frivolity and transience of the tone of those threats. He makes his enmity to American values clear when he suggests that the Presidency holds absolute power, through which he will be able to end opposition—whether by questioning the ownership of newspapers or talking about changing libel laws or threatening to take away F.C.C. licenses

To say “Well, he would not really have the power to accomplish that” is to misunderstand the nature of thin-skinned authoritarians in power. They do not arrive in office and discover, as constitutionalists do, that their capabilities are more limited than they imagined. They arrive, and then make their power as large as they can.

If Trump came to power, there is a decent chance that the American experiment would be over. This is not a hyperbolic prediction; it is not a hysterical prediction; it is simply a candid reading of what history tells us happens in countries with leaders like Trump.

we do appear to be getting, in place of the once famous Big Lie of the nineteen-thirties, a sordid blizzard of lies. The Big Lie was fit for a time of processionals and nighttime rallies, and films that featured them. The blizzard of lies is made for Twitter and the quick hit of an impulse culture. Trump’s lies arrive with such rapidity that before one can be refuted a new one comes to take its place.

The American Republic stands threatened by the first overtly anti-democratic leader of a large party in its modern history—an authoritarian with no grasp of history, no impulse control, and no apparent barriers on his will to power.

The right thing to do, for everyone who believes in liberal democracy, is to gather around and work to defeat him on Election Day. Instead, we seem to be either engaged in parochial feuding or caught by habits of tribal hatred so ingrained that they have become impossible to escape even at moments of maximum danger.

Hitler wasn’t Hitler—until he was. At each step of the way, the shock was tempered by acceptance. It depended on conservatives pretending he wasn’t so bad, compared with the Communists, while at the same time the militant left decided that their real enemies were the moderate leftists, who were really indistinguishable from the Nazis.

Countries don’t really recover from being taken over by unstable authoritarian nationalists of any political bent, left or right—not by Peróns or Castros or Putins or Francos or Lenins

The nation may survive, but the wound to hope and order will never fully heal. Ask Argentinians or Chileans or Venezuelans or Russians or Italians—or Germans.

The national psyche never gets over learning that its institutions are that fragile and their ability to resist a dictator that weak.

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.

The straight-A student said she hoped to study neuroscience at Harvard one day.

She hopes they see from her experiences that education is the best way to avoid repeating her struggles.

“This experience showed me that I’m raising well-rounded young ladies who can adapt to any situation and make the best of it,” Ms. Hopewell said. “Their capabilities are endless.”

Protesters are saying, in effect, “If we can pull this off, imagine what else we can do.”

The march drew a quarter of a million people, but it represented much more effort, commitment and preparation than would a protest of similar size today.

This is one reason that recent large protests have had less effect on policy than many were led to expect.

The protesters failed to transform into an electoral force capable of defeating him in the 2004 election.

Two enormous protests, two disappointing results. Similar sequences of events have played out in other parts of the world.

A large protest today is less like the March on Washington in 1963 and more like Rosa Parks’s refusal to move to the back of the bus. What used to be an endpoint is now an initial spark.

But the Tea Party protesters then got to work on a ferociously focused agenda: identifying and supporting primary candidates to challenge Republicans who did not agree with their demands, keeping close tabs on legislation and pressuring politicians who deviated from a Tea Party platform.

But there is no magic power to marching in the streets that, on its own, leads to any other kind of result.
