What is learning for if it doesn't lead to wisdom? That's a question worth asking in light of an ongoing cosmological street fight being waged (remarkably) in broad media daylight. The rumble tumbled into the public eye with Lawrence Krauss' new book A Universe From Nothing. But before the scathing New York Times review and an acerbic rebuttal in The Atlantic, this physics vs. philosophy smack-down was brewing in academic back alleys for decades. At stake is a critical question living deep inside the heart of modern foundational physics: What are the limits of science?

Berlin, February 14, 2012 - The Document Foundation announces LibreOffice 3.5, the third major release of "the best free office suite ever", which shows to end users the improvements derived from the development strategy adopted since September 2010. LibreOffice 3.5 derives from the combined effort of full time hackers - the largest group of experienced OOo code developers - and volunteer hackers, coordinated by the Engineering Steering Committee.

I've visited Singapore a few times in recent years and been impressed with its wealth and modernity. I was also quite aware of its world-leading programs in mathematics education and naturally noted that one of the candidates for president was Tony Tan, who has a Ph.D. in applied mathematics. Tan won the very close election and joined the government of Prime Minister Lee Hsien Loong, who also has a degree in mathematics.

Summary:  How can we reclaim and reform America?  Here is a five-step program.  All it requires is time and effort.  This is a content-free path.  I do not know where this will take us.  Only that if widely followed America will become what we wish it to be.  No matter what the outcome, we will meet the future as citizens.  Not sheep.

What's in store for robotics in 2012? Nearly a quarter of the year is already behind us, but we thought we'd spend some time looking at the months ahead and make some predictions about what's going to be big in robotics.

The aim of the Askemos project is to enable reliable and justiciable data processing, with the goal of producing "Software that can last 200 years." The first implementations of an Askemos peer can be obtained from ball.askemos.org. The Askemos web site itself is served from the Askemos/BALL development network. Follow here for more details. Note that Askemos concerns the abstract specification exclusively; including data formats, protocols, service interfaces etc. - not the actual implementations. Askemos combines incorruptible privilege delegation and non-repudiable replication of communicating processes into a trustworthy network. Physical machines under control of their operators execute applications processes under permanent multilateral audit. The network's honest majority of hosts provides users with exclusive control, and thus real ownership of processes. Askemos models a kind of "virtual constitutional state" where physical hosts bear witness to the interactions of virtual agents (akin to citizens). Self verifying identifiers can confirm that original documents have not beentampered with. The real potential for using Askemos is for identity and time stamp services, informationmanagement in public administration and libraries attaching metadata and archives, with the goal of establishing robust systems that can endure for centuries. German tax law, for instance, has storage requirements, which makes Askemos interesting even for private, individual use. Also Activist groups, non-profits and people who desire privacy and reliability in a chaotic and unpredictable world have much to gain from this software.

AT 7 years old, Gilad Elbaz wrote, "I want to be a rich mathematician and very smart." That, he figured, would help him "discover things like time machines, robots and machines that can answer any question."

The Google+ team continues to graduate features from its sandbox into prime time for its Hangouts product. Last week, the company announced the addition of Google Docs into Hangouts, and today the service has officially added the ability to make phone calls from within a Hangout as well.

A lot of times I have people asking me about interfacing a fingerprint sensor to an arduino for their school projects.

Are the financial markets rational?  It's a tough claim to make as share prices and bond yields zoom up and down during a single day, hour, or even second, sometimes without any obvious reasons.  Yet for the first time in human history, the markets may be approaching the ideal of rationality that economists have long cherished.

Millions of people log on to Lumosity daily to flex their brain muscles--and hopefully improve memory, attention and general cognitive performance in the process.  But this brain training site has recently garnered attention for a large-scale survey which found that better brain performance was linked to 7 hours of sleep per night,  aerobic activity 2-3 times per week and a daily cocktail.  While the overall efficacy of brain training remains hotly debated, Michael Scanlon, co-founder and Chief Scientific Officer of Lumos Labs (creator of Lumosity), discusses the findings from the study, what surprised him most and what we can take away from correlational data. 

For the first time, the international organization has set a date for the moment when the "Age of America" will end and the U.S. economy will be overtaken by that of China And it's a lot closer than you may think.

Memories can be reactivated during sleep and strengthened in the process,  Northwestern University research suggests. In the Northwestern study, research participants learned how to play two artificially generated musical tunes with well-timed key presses. Then while the participants took a 90-minute nap, the researchers presented one of the tunes that had been practiced, but not the other

Reproducibility is a key part of science, even though almost nobody does the same experiment twice. A lab will generally repeat an experiment several times and look for results before they get published. But, once that paper is published, people tend to look for reproducibility in other ways, testing the consequences of a finding, extending it to new contexts or different populations. Almost nobody goes back and repeats something that's already been published, though. But maybe they should. At least that's the thinking behind a new effort called the Reproducibility Initiative, a project hosted by the Science Exchange and supported by Nature, PLoS, and the Rockefeller University Press.

This is an army of 'Chef Cui' noodle-shaving robots designed and manufactured by Cui Runquan. The robots were designed to cut noodles from a block of dough cheaper and more efficiently than humans can. Plus today's youth don't want to work as noodle cutters. Kids! I spent two summers as a teen peeling potatoes at summer camp, and do you hear me complaining? Hell no, I got that out of my system a long time ago. It really did suck though.

The last time we ran into Ben Heck, the tinkerer extraordinaire was waxing poetic at Maker Faire about the Raspberry Pi and cheese curds. One more thing he also talked about, however, was his latest 3D printer project, which he now explains in greater detail in the latest episode of the Ben Heck Show. Improvements made to the device include use of a Birdstruder for easier access to the filament and the ability to print off an SD card if you don't have a computer handy. The 3D printer also sports an expanded 200-square-millimeter print area with a solid copper cover for added sturdiness and accuracy. As usual, size matters for Mr. Heckendorn so the device got a boost in portability, now neatly folding James Bond-like into a briefcase that measures 18 x 14 x 4.2 inches. Interested in a briefcase printer of your own? Well, Heckendorn mentioned during the Maker Faire interview that he's already working on an improved version and thinking about putting it up on Kickstarter so hope springs eternal. In the meantime, you can glean more details about the device by checking out the video after the break.

Certain About Nothing In "US Corporates Shy to Offer Guidance," the Financial Times reports that those who are at the economy's front lines have a less than clear vision of where things are headed:

The Yomiuri Shimbun It may be possible to travel to space in an elevator as early as 2050, a major construction company has announced. Obayashi Corp., headquartered in Tokyo, on Monday unveiled a project to build a gigantic elevator that would transport passengers to a station 36,000 kilometers above the Earth. For the envisaged project, the company would utilize carbon nanotubes, which are 20 times stronger than steel, to produce cables for the space elevator.
