    The data we're including in this first launch represents just a small fraction of all the interesting public data available on the web. There are statistics for prices of cookies, CO2 emissions, asthma frequency, high school graduation rates, bakers' salaries, number of wildfires, and the list goes on. Reliable information about these kinds of things exists thanks to the hard work of data collectors gathering countless survey forms, and of careful statisticians estimating meaningful indicators that make hidden patterns of the world visible to the eye. All the data we've used in this first launch are produced and published by the U.S. Bureau of Labor Statistics and the U.S. Census Bureau's Population Division. They did the hard work! We just made the data a bit easier to find and use.

  • The experiments, which spanned more than a decade, suggest that the electron differs from being round by less than 0.000000000000000000000000001 cm. Just so you can get an estimate, if the electron were as big as the solar system, it would still be spherical to within the width of a human hair.
  • a team from the Imperial College London concluded that the electron is actually incredibly round, thus making the most accurate estimate of its shape.

    Browse local data from the Census Bureau's American Community Survey, based on samples from 2005 to 2009. Because these figures are based on samples, they are subject to a margin of error, particularly in places with a low population, and are best regarded as estimates.

    "Artificial Intelligence is a hot topic at the moment, with estimates varying wildly about how many jobs will be replaced by machine learning algorithms. Whatever the outcome, in reality, it is clear that schools will need to change, in order to prepare their students for the resulting impact on society and the skills needed for future employment."

CHRISTIE HEMM KLOK/WIRED SO YOU'RE A parent, thinking about sending your 7-year-old to this rogue startup of a school you heard about from your friend's neighbor's sister. It's prospective parent information day, and you make the trek to San Francisco's South of Market neighborhood. You walk up to the second floor of the school, file into a glass-walled conference room overlooking a classroom, and take a seat alongside dozens of other parents who, like you, feel that public schools-with their endless bubble-filled tests, 38-kid classrooms, and antiquated approach to learning-just aren't cutting it. At the same time, you're thinking: this school is kind of weird. On one side of the glass is a cheery little scene, with two teachers leading two different middle school lessons on opposite ends of the room. But on the other side is something altogether unusual: an airy and open office with vaulted ceilings, sunlight streaming onto low-slung couches, and rows of hoodie-wearing employees typing away on their computers while munching on free snacks from the kitchen. And while you can't quite be sure, you think that might be a robot on wheels roaming about. Then there's the guy who's standing at the front of the conference room, the school's founder. Dressed in the San Francisco standard issue t-shirt and jeans, he's unlike any school administrator you've ever met. But the more he talks about how this school uses technology to enhance and individualize education, the more you start to like what he has to say. And so, if you are truly fed up with the school stat

It is interesting to note that in six of the areas, the time estimates actually increased. Note: NA is listed in some of the responses for 2003 because these are new questions in 2009.

  • A substantial literature documents large variation in teacher effectiveness at raising student achievement, providing motivation to identify highly effective and ineffective teachers early in their careers. Using data from New York City public schools, we estimate whether subjective evaluations of teacher effectiveness have predictive power for the achievement gains made by teachers’ future students. We find that these subjective evaluations have substantial power, comparable with and complementary to objective measures of teacher effectiveness taken from a teacher’s first year in the classroom.

  • Try turning the question around:  How do other people usually get where they need to go on time?  What steps do they take to avoid being late?  First, they check the clock every so often, particularly when they know there's a deadline approaching.  They estimate how much time they'll need to get wherever they're going and thus what time they'll need to leave where they are.  They pause to figure out how long it will take to finish what they're currently doing and get ready for whatever is coming next.  And then they adjust their behavior accordingly
  • I suspect that those who chronically show up late don't do these things.  Perhaps they have a tendency to lose themselves in whatever they're currently doing and don't discover what time it is until it's too late.
  • Roland Gesthuizen on 23 Jul 12
     
    "why some people never seem to be on time.  Surely you know such people, perhaps quite well.  Indeed, if you can overcome a rising bubble of defensiveness, you may admit that you are one of those people.  Everyone is late now and then, of course, but I'm talking about folks who habitually show up after an event has started.."

When the 'A' in U.C.L.A. Stands for 'Achievement' - Campaign Spotlight - NYTimes.com - 0 views

  • The campaign, now getting under way, is for the University of California, Los Angeles. The campaign proclaims that U.C.L.A. is the home of “the optimists,” people who are risk-takers, rule-breakers and game-changers.
  • The campaign is the first for U.C.L.A. from an agency named 160 Over 90, which is based in Philadelphia and recently opened an office in Newport Beach, Calif.
  • That work underscores the growing presence of universities and colleges as advertisers in the media. Their goals include selling themselves to prospective students and the parents of those students, seeking donations from alumni, recruiting faculty members and improving their standings in various surveys.
  • ...7 more annotations...
  • The agency has also created ads for institutions of higher learning like Michigan State University, Loyola University Maryland and the University of Dayton.
  • The campaign has a section devoted to it on the U.C.L.A. Web site, ucla.edu/optimists, and is getting shout-outs on the U.C.L.A. fan page on Facebook and on the U.C.L.A. Twitter feed, where those who send messages are asked to use the hashtag #optimists.
  • The U.C.L.A. campaign has a small budget, estimated at less than $500,000, for a couple of reasons. One is that much of the campaign is appearing online; there is also print advertising, in newspapers.
  • The video clip can also be watched on YouTube.
  • The new campaign is meant to celebrate “the optimism that abounds on our campus,” she adds, “even in challenging times,” and shine a spotlight on “the dynamism and vitality” as well as the history and legacy of the university.
  • The way to do that, Ms. Turteltaub says, is to focus on “the icons” from U.C.L.A. “who made their mark in whatever fields they choose” and describe their “accomplishment, success, barrier-breaking.”
  • “This is the place that gives you the opportunity to be a game-changer,” Ms. Turteltaub says, “and you’ll choose the game.”

  • But Wait! There's More.Again
  • There is yet another advantage ETFs have over mutual funds
  • and that is their tax benefit
  • However, unlike mutual funds, ETFs do not sell stocks to pay for redemptions
  • As people withdraw their money from a mutual fund, the mutual fund must sell securities to cover those redemptions. So, every time the mutual fund sells a stock, you have to pay capital gains tax on it.
  • This being the case, the capital gains that you must pay on an ETF are much less than that of a mutual fund because of the lack of capital gains.
  • Danger, Will Robinson!
  • However, be careful not to confuse
  • an ETF
  • ith an Indexed Mutual Fund
  • Indexed Mutual Funds are mutual funds provided by a mutual fund company
  • But, just like any other mutual fund, you have to pay fees
  • Vanguard will charge you managerial fees to set up and manage the fund.
  • The ETF's Potential Disadvantage
  • they do have a potential drawback
  • What it really depends upon is how much you are going to invest and how frequently you are going to invest.
  • If you're only going to invest $200 a month in an ETF, the $20 commission results in an immediate 10% loss,
  • Just something to think about before you jump into ETFs.

  • nd dairy regulation decreased, driving a new incentive and ability to trade with other nations.
  • s a result, the dairy market tends now toward undersupply.
  • But from December 2013 to February 2014, Chinese demand grew to 20-25% of all global dairy imports, with much of the supply coming from the US and New Zealand.
  • New Zealand is the world's largest dairy exporter, accounting for nearly one-third of the global dairy trade.
  • Many of the nation's cows graze in fields, and a big drought in 2013 caused national milk production to plummet nearly 30%.
  • The US started exporting more dairy, capturing more international market share but pushing up domestic prices.
  • It's not all bad news for New Zealand, though. Traditionally, when the price of dairy goes up, farmers expand operations and produce more milk, thus lowering prices down the line.
  • The increase in supply could eventually lead to cheaper prices in the US, but not for several months.
  • US franchises including KFC, Ihop, Subway, The Cheesecake Factory, Jamba Juice and Papa John's Pizza have all staked claims in the Middle East, with more chains looking to follow.
  • A young, newly urbanised population in the Middle East is demanding more dairy imports.
  • That removed an estimated $6.6bn (£4bn) in annual dairy trade from the global market. In 2013, the EU alone exported $3bn of dairy to Russia, of which cheese accounted for more than one-third.
  • In response, the European Commission has announced it will provide financial support to the dairy industry, subsidising private storage of cheese, skimmed milk powder and butter until they can be sold at a later date.
  • But it will take a little while to see those changes reflected in American supermarkets.

  • The machine is effective in recycling different kinds of plastic into oil.
  • Utilization doesn't just take into account the 20 percent of recycled plastic. But it also considers the incinerated 52 percent used for energy recovery like generating electric power or heat. Akinori Ito says "If we burn the plastic, we generate toxins and a large amount of CO2. If we convert it into oil, we prohibit CO2 production and at the same time, increase people's awareness about the value of plastic garbage"
  • Oil from Shale: Oil can be extracted from this fine grained, organic rich, sedimentary rock through pyrolysis, thermal dissolution or hyderogentation. Shale contains high concentrations of organic chemical compounds known as Kerogen. From this solid mixture, oil is extracted through chemical process. Shale can be effective converted into combustible oil shale gas and liquid hydrocarbons (shale oil). Global deposits of Shale are estimated to be around 2.8 trillion to 3.3 trillion barrels of restorable oil. Planet earth is blessed with about 600 known oil shale deposits, most of which is found in United States of America. Although several countries have oil hale deposits, known deposits of economic importance is found only in 33 countries.

  • “It certainly suggests the drugs are being abused,” says Gordon Floyd, president and CEO of Children's Mental Health Ontario. “There's a desire for the quick fix … the idea that – ‘oh, we'll fix this with a pill' – rather than spend a few months in counselling, is pretty appealing.”
  • ADHD is one of the most commonly diagnosed disorders of childhood, with core features that include an inability to focus, and hyper and impulsive behaviour. Increasingly, it's seen as a chronic condition that 60 per cent of kids never outgrow and one that experts estimate affects five per cent of children worldwide.
  • Boys are four times more likely to develop autism, three times more likely to suffer dyslexia, and two to three times more likely to be diagnosed with ADHD.

Consumption totaled 3.6 zettabytes and 10,845 trillion words, corresponding to 100,500 words and 34 gigabytes for an average person on an average day. A zettabyte is 10 to the 21st power bytes, a million million gigabytes. These estimates are from an analysis of more than 20 different sources of information, from very old (newspapers and books) to very new (portable computer games, satellite radio, and Internet video).
