And one of the hottest new sources of Big Data, reports the WSJ's Alexandra Alter in Your E-Book Is Reading You, is the estimated 40 million e-readers and 65 million tablets in use in the U.S. that are ripe for the picking by data scientists working for Amazon, Apple, Google, and Barnes & Noble. Some privacy watchdogs argue that e-book users should be protected from having their digital reading habits recorded.

Freshly Exhumed writes "In a speech Wednesday, ExxonMobil CEO Rex Tillerson acknowledged that burning of fossil fuels is warming the planet, but said society will be able to adapt. The risks of oil and gas drilling are well understood and can be mitigated, he said. And dependence on other nations for oil is not a concern as long as access to supply is certain, he said. Tillerson blamed a public that is "illiterate" in science and math, a "lazy" press, and advocacy groups that "manufacture fear" for energy misconceptions in a speech at the Council on Foreign Relations."

gollum123 sends this excerpt from the NY Times: "Arguing against immigration policies that force foreign-born innovators to leave the United States, a new study (PDF) to be released on Tuesday shows that immigrants played a role in more than three out of four patents at the nation's top research universities. Conducted by the Partnership for a New American Economy, a nonprofit group co-founded by Mayor Michael Bloomberg of New York, the study notes that nearly all the patents were in science, technology, engineering and math, the so-called STEM fields that are a crucial driver of job growth. ... The Partnership for a New American Economy released a paper in May saying that other nations were aggressively courting highly skilled citizens who had settled in the United States, urging them to return to their home countries. The partnership supports legislation that would make it easier for foreign-born STEM graduates and entrepreneurs to stay in the United States. ... The study notes that nine out of 10 patents at the University of Illinois system in 2011 had at least one foreign-born inventor. Of those, 64 percent had a foreign inventor who was not yet a professor but rather a student, researcher or postdoctoral fellow, a group more likely to face immigration problems."

An anonymous reader writes "As a calculus professor for a small undergraduate institution, I normally lecture students who are majoring in the natural (or 'hard') sciences, such as mathematics, physics, and computer science. In fact, I have done so for almost thirteen years. However, for the first time this fall semester, we have a shortage of professors on our hands. As a result of this, I have been asked to teach a general education statistics class. Such classes are a major requirement for the large psychology student body we have here. I have never lectured social science students in any mathematics-related classes. My question to the Slashdot community is as follows: What are your experiences with teaching natural science classes to social science students? How is the experience the same or different in comparison to natural science students who may be more adept to the nuances of mathematics and other similar fields?"

arisvega writes "A recent publication (for the math-versed) proposing the deployment of a Solar-powered, space-borne fleet of LASER cannons that would deflect Earth-bound asteroids caught the attention of international news agencies. Do you think this ambition can in reasonable time turn into a fair-priced, life-saving (or indeed Biosphere-saving!) project, that will be to the benefit of all mankind? How threatened would you feel from the possibility of this proposed array being hijacked by extremely depraved individuals, ones capable or guilty of great crimes? And, are you not glad that now someone has published a paper on it, so Megacorp cannot 'patent' this Earth-saving idea?"

tekgoblin writes "Well this is pretty awesome, Valve has made an entrance into the education sector. They plan to release a new version of Steam for education uses in schools. Valve will call this service Steam for Schools, an education version of the Steam client that allows administrators to limit what its users can access. The idea of Steam for Schools is to use the platform as a teaching aid. Valve has already put together a number of educational lesson plans for using Portal 2 and its level editor to teach math and physics."

snoop.daub writes "R.A. Dickey, pitcher for the New York Mets, has been in the news this week after two dominant pitching performances in a row, holding opponents to one hit in each of the games for the first time since Dave Stieb did it in 1988. He has taken over as the league's only knuckleball pitcher after Tim Wakefield retired last season. But just what is it about the knuckleball that makes it hard to hit? Conventional wisdom has it that the lack of spin on the knuckleball causes it to move in completely unpredictable ways, even changing directions in mid-flight. In the last few years, there has been a lot of good science done to understand baseball pitch trajectories, and a few months ago Prof. Alan M. Nathan showed that knuckleballs aren't really so different from other pitches. It turns out that the same 9-parameter equation that can be used to describe other pitch trajectories applies just as well to the knuckleball. The difference appears to be that, like in a chaotic system, knuckleballs depend sensitively on the initial conditions, so that small changes can cause randomly different forces at the start of the pitch which determine the resultant trajectory. Much of this and similar work depends on the Pitchf/x tool, which has recorded the complete trajectory, spin angle and spin rate of every MLB pitch since 2007! Baseball really does have the best sports stats geeks."

New submitter sjdupont writes "A trio of University of South Florida (USF) engineering graduate students have decided to make a change in science, technology, engineering, and mathematics (STEM) education in an unusual and exciting way: by creating their own superhero personas and dressing in costumes as members of the Scientific League of Superheroes. Focused on elementary education, they have created a unique education program called the Superhero Training Network, a curriculum-based video series designed for the classroom which focuses on teaching STEM topics while engaging students in a fun way. Fifth grade classrooms in Hillsborough County (Florida) pilot tested the series during the 2011-2012 school year and enjoyed visits from the scientific superheroes to experience scientific demonstrations and participate in hands-on activities."

judgecorp writes "Fujitsu and partners have cracked a cryptogram which used 278-digit (923 bit) pairing-based cryptography. The technology was proposed as a next-generation standard, but Fujitsu cracked it, at this level in just over 148 days using 21 personal computers." Reader Thorfinn.au adds a snippet from Fujitsu's announcement of the break: "This was an extremely challenging problem as it required several hundred times computational power compared with the previous world record of 204 digits (676 bits). We were able to overcome this problem by making good use of various new technologies, that is, a technique optimizing parameter setting that uses computer algebra, a two dimensional search algorithm extended from the linear search, and by using our efficient programing techniques to calculate a solution of an equation from a huge number of data, as well as the parallel programming technology that maximizes computer power."

isoloisti writes "Three UK economists got access to national data on bank robberies. The conclusion is that robbing banks pays, but not very much. Average take is about $19k per person per robbery. But, there's a 20% chance of being caught per raid. To make an average income, a robber needs to do two jobs per year, and has greater than 50% chance to be in the slammer after 2 years."

ideonexus writes "Years ago Nate Silver of FiveThirtyEight.com, a blog seeking to educate the public about elections forecasting, established his model as one of the most accurate in existence, rising from a fairly unknown statistician working in baseball to one of the most respected names in election forecasting. In this article he describes all the factors that go into his predictions. A fascinating overview of the process of modeling a chaotic system."

TaeKwonDood writes "We've all seen the stories about how 'dismal' science education in America is. It turns out that it's kind of a straw man. America has long led the world in science but the 'average' score for Americans on standardized tests has never been good. Instead, every 2 years American kids get better but we keep being told things are terrible. Here is why."

theodp writes "In mid-May, the Department of Homeland Security quietly expanded a program that allows foreign science, technology, engineering and math grads to work in the U.S. for 29 months without a work visa. 'Attracting the best and brightest international talent to our colleges and universities and enabling them to contribute to their professional growth is an important part of our nation's economic, scientific and technological competitiveness,' explained DHS Chief Janet Napolitano. But last week, Senator Chuck Grassley called on the GAO to 'fully investigate' the student visa program, citing reports of abuse and other concerns in his letter. Now, Computerworld reports that the DHS STEM Visa Extension Program continues to be dominated by Stratford University and the University of Bridgeport (as it was in 2010), prompting some tongues to wag. It is 'obvious to any reasonable person that the schools producing most of the OPT students are not prestigious research universities,' quipped policy analyst Daniel Costa, 'which means that many of the OPT students across the country are not in fact the "best and brightest."' While conceding that top students can come from lesser-known schools, 'those will be the exception to the rule,' argued Costa, who suggested the government should include performance metrics in the OPT program, such as grades and university rankings."

sciencehabit writes with an interesting article about the (surprisingly not well studied) effects of rain on flying insects. From the article: "When a raindrop hits a mosquito, it's the equivalent of one of us being slammed into by a bus. And yet the bug will survive and keep flying. That's the conclusion of a team of engineers and biologists, which used a combination of real-time video and sophisticated math to demonstrate that the light insect's rugged construction allows the mosquito to shrug off the onslaught of even the largest raindrop. The findings offer little aid in controlling the pest but could help engineers improve the design of tiny flying robots." Bats, unfortunately, aren't so lucky: "...these furry fliers need about twice as much energy to power through the rain compared with dry conditions."

First time accepted submitter badmojo17 writes "After achieving her lifelong dream of becoming a public school math teacher, my wife has found the profession to be much more frustrating than she ever expected. She could deal with having a group of disrespectful criminals as students if she had competent administrators supporting her, but the sad truth is that her administration causes more problems on a daily basis than her students do. Our question is this: what other professions are open to a bright young woman with a bachelor's degree in math and a master's degree in education? Without further education, what types of positions or companies might be interested in her as an employee?"

SicariusMan writes "The age old question: do Guinness and other stouts' bubbles really sink, or is it an optical illusion? Well, some mathematicians have figured it out." Full paper via arXiv; From the article: "To analyze the effect of different glass shapes, the mathematicians modeled Guinness beer containing randomly distributed bubbles in both a pint glass and an anti-pint glass (i.e., an upside-down pint). An elongated swirling vortex forms in both glasses, but in the anti-pint glass the vortex rotates in the opposite direction, causing an upward flow of fluid and bubbles near the wall of the glass."

Fluffeh writes "The folks that push 'Anti-Piracy' and 'Copying is Stealing' seem to often request that Google pre-screens content going up on YouTube and of course expect Google to cover the costs. No-one ever really asks the question how much it would cost, but some nicely laid out math by a curious mind points to a pretty hefty figure indeed. Starting with who to employ, their salary expectations and how many people it would take to cover the 72 hours of content uploaded every minute, the numbers start to get pretty large, pretty quickly. US$37 billion a year. Now compare that to Google's revenue for last year."

First time accepted submitter johnsnails writes "A German 16-year-old, Shouryya Ray, solved two fundamental particle dynamic theories posed by Sir Isaac Newton, which until recently required the use of powerful computers. He worked out how to calculate exactly the path of a projectile under gravity and subject to air resistance. Shouryya solved the problem while working on a school project. From the article: 'Mr Ray won a research award for his efforts and has been labeled a genius by the German media, but he put it down to "curiosity and schoolboy naivety." "When it was explained to us that the problems had no solutions, I thought to myself, 'well, there's no harm in trying,'" he said.'"

benrothke writes "Elementary Information Security, based on its title, weight and page length, I assumed was filled with mindless screen shots of elementary information security topics, written with a large font, in order to jack up the page count. Such an approach is typical of far too many security books. With that, if there ever was a misnomer of title, Elementary Information Security is it." Read below for the rest of Ben's review

Barence writes "Computer scientists have unveiled a computer chip that turns traditional thinking about mathematical accuracy on its head by fudging calculations. The concept works by allowing processing components — such as hardware for adding and multiplying numbers — to make a few mistakes, which means they are not working as hard, and so use less power and get through tasks more quickly. The Rice University researchers say prototypes are 15 times more efficient and could be used in some applications without having a negative effect."
