Quantum Physics Mathematics

shared by manhefnawi on 12 Jun 18 - No Cached
  • What, then, are you supposed to do when the mathematics gets more abstract? What do you do when you get to General Relativity, or Quantum Field Theory, or even more far afield into the speculative realms of cosmic inflation, extra dimensions, grand unified theories, or string theory? The mathematical structures that you build to describe these possibilities simply are what they are; on their own, they won't offer you any physical insights. But if you can pull out either observable quantities, or connections to physically observable quantities, that's when you start crossing over into something that you can test and observe.
  • Now, string theory (or, more accurately, string theories) have their own constraints governing them, as do the forces in our Universe, so it isn't provably clear that there's a one-to-one correspondence between our four-dimensional Universe with gravity, electromagnetism, and the nuclear forces and any version of string theory. It's an interesting conjecture, and it has found some applications to the real world: in the study of quark-gluon plasmas. In that sense, it's more than mathematics: it's physics. But where it strays from physics into pure mathematics is not yet fully determined.
  • If you describe the Universe precisely, and you can make quantitative predictions about it, you're physics. If those predictions turn out to be accurate and reflective of reality, then you're physics that's correct and useful. If those predictions are demonstrably wrong, you're physics that doesn't describe our Universe: you're a failed attempt at a physical theory. But if your equations have no connection at all to the physical Universe, and cannot be related to anything you can ever hope to someday observe or measure, you're firmly in the realm of mathematics; the divorce from physics will then be final. Mathematics is the language we use to describe physics, but not everything mathematical is physically meaningful. The connection, and where it breaks down, can only be determined by looking at the Universe itself.

      Both conservatives and liberals, people on any side of the argument, are trying to twist it to make themselves look better
  • But none of the other four deaths were at the hands of the protesters: the only other person killed with deliberate violence was a pro-Trump protester, Ashli Babbitt, unarmed when shot in the neck by a police officer at close range. The other three deaths were all pro-Trump protesters: Kevin Greeson, who died of a heart attack outside the Capitol; Benjamin Philips, 50, “the founder of a pro-Trump website called Trumparoo,” who died of a stroke that day; and Rosanne Boyland, a fanatical Trump supporter whom the Times says was inadvertently “killed in a crush of fellow rioters during their attempt to fight through a police line.”

  • With the impeachment trial now over, the articles are now rewritten to reflect that the original story was false. But there was nothing done by The New York Times to explain an error of this magnitude, let alone to try to undo the damage it did by misleading the public. They did not expressly retract or even “correct” the story.

  • So it matters a great deal legally, but also politically, if the U.S. really did suffer an armed insurrection and continues to face one. Though there is no controlling, clear definition, that term usually connotes not a three-hour riot but an ongoing, serious plot by a faction of the citizenry to overthrow or otherwise subvert the government.
  • people rightly conclude the propaganda is deliberate and trust in journalism erodes further.
  • One can — and should — condemn the January 6 riot without inflating the threat it posed. And one can — and should — insist on both factual accuracy and sober restraint without standing accused of sympathy for the rioters.

What If Fox News Viewers Watched CNN Instead? - Bloomberg - 0 views

fox news experiment trial rival perspectives change of mind research bias

shared by Javier E on 05 Apr 22 - No Cached
  • The establishment of Fox News in the late 1990s forever changed both media and politics in America, transforming the formerly staid world of television news into the series of political shoutfests we know and love-hate today.
  • the question persists: Does watching Fox News actually change voters’ minds?
  • Comparing markets that had received Fox to those where it was not yet available, the study concluded that the presence of Fox News was good for a Republican gain of 0.4 to 0.7 percentage points between the 1996 and 2000 elections. It was a decidedly modest effect — but large enough to sway that super-close election.

  • Only committed conservatives, the theory goes, would bother to tune in to Sean Hannity or Tucker Carlson, so what difference could it make what they say?
  • Broockman and Kalla recruited a sample of regular Fox News viewers and paid a subset of them to watch CNN instead.
  • Then the treatment group of switchers and the control group of non-switchers took three waves of surveys about the news.
  • The results: Not only did CNN and Fox cover different things during the September 2020 survey period, but the audience of committed Fox viewers, which started the month with conservative predispositions, changed their minds on many issues.
  • Switchers were five percentage points more likely to believe that people suffer from long Covid, for example, and six points more likely to believe that many foreign countries did a better job than the U.S. of controlling the virus.
  • They were seven points more likely to support voting by mail. And they were 10 points less likely to believe that supporters of then-candidate Joe Biden were happy when police officers get shot, 11 points less likely to say it’s more important for the president to focus on containing violent protesters than on the coronavirus, and 13 points less likely to agree that if Biden were elected, “we’ll see many more police get shot by Black Lives Matter activists.”
  • These are meaningful differences, even if the group that switched to CNN remained very right-wing in their view of the American political landscape.
  • these are reasonably large changes from a one-month experiment. And they occurred despite the long-term effort of then-President Donald Trump to discredit CNN and other mainstream media outlets.
  • one of the things that switchers changed their minds about was Fox News itself: They became more skeptical that Fox would cover a story that reflected poorly on Trump, even if it were true.
  • This mode of political influence, where partisan media can simply ignore stories that are inconvenient, is a potentially powerful challenge to democratic accountability.
  • It’s also probably not symmetrical. Even media outlets that skew liberal in their coverage generally don’t shy away from covering the Covid death toll or the rise in inflation.
  • one lesson they can take from this experiment is that nobody is impossible to reach.
  • Broockman and Kalla’s research indicates that information flows at the margin really do matter. Any opportunity to present new facts to people, and new arguments, is valuable.

  • The five biggest technology giants in the U.S. have collectively lost more than $2 trillion of stock market value this year.
  • Start-up founders who were turning away eager investors a few months ago now must make an effort to get more money. (Gasp.)
  • Every couple of years for the past decade, anytime there were some wobbles in technology or moments of doubt, smart people predicted that the growth of the tech economy since the Great Recession couldn’t possibly last.

  • We haven’t seen this combination of economic anxiety and high inflation before. Economists are weighing the risks of a U.S. recession, and companies in many industries are worried that their businesses are slowing.
  • Fast growing start-ups in particular need the faith of investors, customers and employees to keep the momentum going.
  • If within a few months, stock prices bounce back, investors start putting money into start-ups again and the market for initial public offerings unfreezes, the industry might be fine. But if investors stay skittish for many months or years, that could lead to a major shake-up.

Narcissistic bosses stymie knowledge flow, cooperation inside organizations -- ScienceD... - 0 views

  • Narcissism is a prominent trait among top executives, and most people have seen the evidence in their workplaces.
  • These individuals believe they have superior confidence, intelligence and judgment, and will pursue any opportunity to reinforce those inflated self-views and gain admiration. According to new research from the University of Washington, narcissism can also cause knowledge barriers within organizations.
  • Narcissists hinder this knowledge transfer due to a sense of superiority that leads them to overestimate the value of internal knowledge and underestimate the value of external knowledge.
  • ...4 more annotations...
  • Many big companies are what one would describe as multi-business firms, an organizational form where you have a corporate parent and subsidiary units," said co-author Abhinav Gupta
  • "Narcissism affects people's desire to be distinctive," Gupta said. "It's correlated by people wanting glory for themselves. We hypothesized that business-unit heads that have those traits would be the ones to say, 'We don't want to work with you. We have sufficient skills and knowledge and abilities that we will work independently.' That was very strongly borne out based on our research design."
  • The study found that unit-head narcissism can prevent knowledge sharing. That tendency diminished in fast-changing or complex environments because narcissists had an excuse to pursue external ideas. But when businesses have high inter-unit competition, narcissists are more tempted to distinguish themselves from other units.
  • "This research kind of goes against the grain of that. If you create the perception of competition inside an organization, then that will have some downstream effects. You will be essentially foregoing some essential knowledge-sharing activities."

Why The CHIPS and Science Act Is a Climate Bill - The Atlantic - 0 views

  • Over the next five years, the CHIPS Act will direct an estimated $67 billion, or roughly a quarter of its total funding, toward accelerating the growth of zero-carbon industries and conducting climate-relevant research, according to an analysis from RMI, a nonpartisan energy think tank based in Colorado.
  • That means that the CHIPS Act is one of the largest climate bills ever passed by Congress. It exceeds the total amount of money that the government spent on renewable-energy tax credits from 2005 to 2019
  • And it’s more than half the size of the climate spending in President Barack Obama’s 2009 stimulus bill. That’s all the more remarkable because the CHIPS Act was passed by large bipartisan majorities, with 41 Republicans and nearly all Democrats supporting it in the House and the Senate.
  • ...15 more annotations...
  • The law, for instance, establishes a new $20 billion Directorate for Technology, which will specialize in pushing new technologies from the prototype stage into the mass market. It is meant to prevent what happened with the solar industry—where America invented a new technology, only to lose out on commercializing it—from happening again
  • Within a few years, when the funding has fully ramped up, the government will spend roughly $80 billion a year on accelerating the development and deployment of zero-carbon energy and preparing for the impacts of climate change. That exceeds the GDP of about 120 of the 192 countries that have signed the Paris Agreement on Climate Change
  • By the end of the decade, the federal government will have spent more than $521 billion
  • the bill’s programs focus on the bleeding edge of the decarbonization problem, investing money in technology that should lower emissions in the 2030s and beyond.
  • The International Energy Association has estimated that almost half of global emissions reductions by 2050 will come from technologies that exist only as prototypes or demonstration projects today.
  • To get those technologies ready in time, we need to deploy those new ideas as fast as we can, then rapidly get them to commercial scale, Carey said. “What used to take two decades now needs to take six to 10 years.” That’s what the CHIPS Act is supposed to do
  • When viewed with the Inflation Reduction Act, which the House is poised to pass later this week, and last year’s bipartisan infrastructure law, a major shift in congressional climate spending comes into focus. According to the RMI analysis, these three laws are set to more than triple the federal government’s average annual spending on climate and clean energy this decade, compared with the 2010s.
  • Congress has explicitly tasked the new office with studying “natural and anthropogenic disaster prevention or mitigation” as well as “advanced energy and industrial efficiency technologies,” including next-generation nuclear reactors.
  • The bill also directs about $12 billion in new research, development, and demonstration funding to the Department of Energy, according to RMI’s estimate. That includes doubling the budget for ARPA-E, the department’s advanced-energy-projects skunk works.
  • it allocates billions to upgrade facilities at the government’s in-house defense and energy research institutes, including the National Renewable Energy Laboratory, the Princeton Plasma Physics Laboratory, and Berkeley Lab, which conducts environmental-science research.
  • RMI’s estimate of the climate spending in the CHIPS bill should be understood as just that: an estimate. The bill text rarely specifies how much of its new funding should go to climate issues.
  • When you add CHIPS, the IRA, and the infrastructure law together, Washington appears to be unifying behind a new industrial policy, focused not only on semiconductors and defense technology but clean energy
  • The three bills combine to form a “a coordinated, strategic policy for accelerating the transition to the technologies that are going to define the 21st century,”
  • scholars and experts have speculated about whether industrial policy—the intentional use of law to nurture and grow certain industries—might make a comeback to help fight climate change. Industrial policy was central to some of the Green New Deal’s original pitch, and it has helped China develop a commanding lead in the global solar industry.
  • “Industrial policy,” he said, “is back.”

  • In short, narcissism is a drive to feel special and unique.
  • To some extent, narcissistic traits exist in all of us, and a little narcissism isn’t a bad thing. In fact, research has shown that viewing ourselves through rose-colored glasses, a concept known as self-enhancement, can help us cope with adversity.
  • Narcissism is most problematic when people become dependent on the feeling of superiority and seek it at all costs, displaying what Dr. Malkin calls the “triple E”: entitlement, exploitation and a lack of empathy.
  • ...9 more annotations...
  • A clinical diagnosis of narcissistic personality disorder can occur when those symptoms become fixed and persistent — they do not come and go. In addition, the disorder causes distress or interferes with relationships, work or other domains.
  • the higher the levels of narcissism, the more people became “desperate, deluded, paranoid, angry, abusive and isolated.”
  • This makes it harder for the narcissist to “charm and impress others,” she said, which then makes it difficult for that person to elicit admiration.
  • Agentic narcissism is what most people think of when they imagine a narcissist. Those who score highly in this dimension are focused on status, power and success.“They see themselves as superior to others, crave admiration and have an inflated sense of self-importance,” Dr. Orth said. “They are typically very confident, assertive and want to be in leadership positions.”
  • Neurotic narcissism is characterized by hypersensitivity. Those who score highly in this dimension “constantly need validation and are very sensitive to criticism and rejection,” Dr. Orth said. “They often experience significant shame, anxiety, emotional instability, insecurity and self-doubt.”
  • Those with antagonistic narcissism often view others as rivals. They tend to be competitive, hostile toward others and willing to put them down to feel superior, Dr. Orth said. They also lack empathy and are exploitative.
  • It is “the core of pathological narcissism,” Dr. Malkin said. “These are bullies.”
  • It’s unclear why narcissism would reduce over time, but Sara Konrath, the director of the Interdisciplinary Program for Empathy and Altruism Research at Indiana University, has found in her own research that empathy increases as we grow older.
  • “Unfortunately, managing a difficult relationship is the best someone intimately involved with most narcissists can hope for,” said Elinor Greenberg, the author of “Borderline, Narcissistic and Schizoid Adaptations: The Pursuit of Love, Admiration and Safety.”
