Comment The real issue (Score 5, Insightful) 311

It's not the *cost* of the iPhone. It's the *black market resale value* that drives theft.

It's uncomfortable allowing a third party to be able to permanently brick your phone or other device, but if that were a commonly-used option, the resale value would quickly drop down close to zero.

As always - back up your data, and don't store important personal information on your easily-stolen device...

Comment This is exciting (Score 4, Insightful) 267

Possibly the most exciting physics news of the year. Although the detection of the Higgs boson was big, it mostly confirmed what existing theory predicted. Interesting, important - but, to some physics, perhaps a bit boring.

If further measurements continue to verify this effect, there are some very interesting new physics to discover.

How many sticks of dynamite would it take at 15 times per second, to eventually push the stated goal of 200MW into the power grid?

1 stick of dynamite == 2.1MJ, if you can believe Wikipedia
15 sticks per second == 32MJ/S = 32MW
200MW/32MW = 6.3 sticks of dynamite exploded 15 times per second.

This assumes 100% efficiency to electricity, of course.

Spend a little time thinking about it, and you will realize that distilled water urban legend is silly. In your mouth, it is mixed with saliva and mucous and whatever else is stuck to your teeth, gums, and tongue. The instant it hits your stomach, it is mixed with stomach acids and whatever you ate recently. I.e. it is no longer pure distilled water. From there, the molecules wander through your body like any other water molecule. Distilling water does not give its component molecules magic properties.

Submission + - First "Goldilocks" exoplanet discovered? (keckobservatory.org)

cunniff writes: According to a press release sent out today, the Keck Observatory on top of Mauna Kea, in Hawaii, has discovered the first "Goldilocks" exoplanet — a rocky Earth-class planet within the liquid water zone of its parent star:

The new planet, known as Gliese 581g, is at a distance that places it squarely in the middle of the star’s “habitable zone” where liquid water could exist on the planet’s surface... Gliese 581g has a mass 3 to 4 times that of the Earth and an orbital period of just under 37 days. Its mass indicates that it is probably a rocky planet with a definite surface and that it has enough gravity to hold on to an atmosphere, according to Vogt.

The parent star, Gliese 581, is a red dwarf in the direction of the constellation Libra.

The Science of Caddyshack 55

astroengine writes "Thirty years after the release of the cult classic comedy Caddyshack, Discovery News has geeked out and gone on the hunt for any trace amount of science they can find in the movie (video). From gopher territoriality to seismic deformation, from pool poop bacteria to the color of lightning, it turns out there's quite a lot of science to talk about..."

Commission Affirms NVIDIA Violated Rambus Patents 35

MojoKid writes "The International Trade Commission has announced its findings in the NVIDIA/Rambus patent infringement lawsuit, and it's not the sort of ruling Team Green would've preferred. The commission found NVIDIA to be in violation of three Rambus patents. The trade panel also granted an injunction Rambus had requested, which theoretically prevents NVIDIA and the various companies attached to the lawsuit (Asus, HP, Palit, and MSI among others) from selling products that contain the infringing IP. The commission's decision this week affirms a January ruling that saw NVIDIA in violation of three Rambus patents while dismissing two additional claims of infringement Rambus made."

Comment Newton's Third Law? (Score 2, Interesting) 609

For every action, there is an equal an opposite reaction. So, when your monster torque motor is spinning the input shaft, surely it is pushing against the counterspinning shafts with exactly that amount of power? In other words - won't the mechanism (electric motor, flywheel, etc.) that keeps the counterspinning shafts running at the desired speed ratios have to overcome this reaction? It's possible that the frictional and mass inertia of the system helps some, but how much?

I'm not an ME, but the explanation of what the required control motor power is relative to input motor power is very thin here. Be very interesting to see what the detailed input / output / control torque & power measurements end up being.
