Samsung Galaxy S III battery tested by GSMArena, lasts as long as your tablet

Source: http://www.engadget.com/2012/05/14/samsung-galaxy-s-iii-battery-tested/

Samsung made much ado over the Galaxy S III's 2,100mAh battery, but we've been wondering whether or not that power pack was a major perk or just a necessity to offset that hefty Exynos 4 Quad. One of what looks to be a growing number of escaped pre-release devices was put through the ringer in battery tests and came out looking spic-and-span: it lasted for just over 10 hours for video and voice, or long enough to make even a tablet like the new iPad or Transformer Prime break a sweat. Web browsing wasn't quite so hot, though, which at a bit over five hours was well behind the seven hours of an iPhone 4S. Don't expect the seemingly infinite battery of the Droid RAZR Maxx, and don't be surprised if final devices handle differently, but those with the international Galaxy S III should make it through at least a few interminable meetings watching their favorite reruns... not that we'd condone such a thing.

Buffalo beats others to the 802.11ac WiFi punch, ships 1.3Gbps router and bridge

As intrigued as we were by the Netgear R6300's high-bandwidth chops, it won't be the one to claim the early 802.11ac WiFi crown with a shipping product. That distinction is instead going to a Buffalo AirStation router and a matching bridge, both of which should be on shelves now. Either can hit the eye-watering 1.3Gbps peak speed of the standard if you get cozy on the 5GHz band -- and if you have a computer or mobile device that recognizes the spec, for that matter. The duo still has a more leisurely paced 2.4GHz, 450Mbps WiFi option as well as a quartet of Ethernet jacks if you prefer your gigabit speeds the old-fashioned way. Both the router and the bridge will set you back $180 each, so there's not much of a penalty versus high-end alternatives to satisfy your need for network speed.

High-power wireless maven Amped Wireless has finally filled that conspicuous dual-band gap in its lineup with the R20000G router. Promising to cover the same 10,000 square feet that its predecessor, it'll flit between the 2.4GHz and 5GHz bands to ensure you can catch unbroken video around your house on the go. Beside the five ethernet jacks you'll find a USB 2.0 port for adding some network storage and the company's usual raft of features. It's available for $180 on Amped's website from today, and should be arriving on store shelves shortly.

Huawei Ascend D1 hits the FCC with pentaband HSPA+

Of the trio of Huawei's Diamond-class smartphones announced at Mobile World Congress in February, the dual-core Ascend D1 got the least amount of buzz. Today, however, the handset gets its opportunity to bask in the spotlight, since it's the first of the group to obtain the FCC's nod of approval. No huge revelations were given, but the docs confirm quadband GSM and pentaband HSPA+ / WCDMA, a welcome treat for AWS fans. As always, we can't assume any carrier affiliation here, but at least we know the unlocked versions will work on AT&T and T-Mobile without a hitch. It looks like Huawei's still on track for a Q2 release -- let's hope the same is true for the D1's older siblings.

This Chart Proves Just How Much SAT Scores Predict Future Success

Source: http://www.businessinsider.com/this-chart-proves-just-how-much-sat-scores-predict-future-success-2012-5

We recently published a chart that shows just how much smarter engineers are than everyone else. Researcher Jonathan Wai of the Duke University Talent Identification Program has another interesting study, Creativity and Occupational Accomplishments Among Intellectually Precocious Youths, which evaluated the top 1% performing youths — identified in the 1970s by a talent search — over 20 years. Wai and two other researchers at Vanderbilt University looked at how SAT scores (taken by students at age 13) of this top 1% group predicted future doctorates, income, patents, and tenure at top U.S. universities.

The chart below compares the top (Q4) and bottom quartile (Q1) of the top 1% of performers on the SAT math section. It shows a significant difference, even among those subsets, in performance later in life (participants were surveyed at around age 33). For example, men in Q4 from one study group earn 13 percent more than those in Q1.

Wai and the other researchers concluded: "Other factors are indeed important, and we agree that being strongly committed and highly motivated is critical for high achievement. Yet, the data reported here on secured doctorates, math–science PhDs, income, patents, and tenure track positions at top U.S. universities collectively falsify the idea that after a certain point more ability does not matter."
