Very much agreed. Nature is not restricted by what we can compute.

It makes me wonder though. It makes sense that we cannot restrict physics to behave according to our computational prowess, but we if we turn this logic onto itself? Is the line of reasoning explored in the article inconsistent with Goedels theorem? Or should I hurry and go back to a computational complexity course?

Like some other commenters, I have a problem with these units.
The most obvious interpretation of the sentence would be to look at how much CO2 a car produces per year. But since the mobile industry has an equivalent CO2 output equal to a number of cars per year, this ends up being an amount of CO2/year/year. Should I interpret this as the rate at which the Co2 emissions are growing then?

Alternatively, it could be the total CO2 output of a car during its lifetime, or the amount of CO2 produced in making a car. In these cases. Any way, either the sentence is wrong, or ambiguous. Now which is the right interpretation?

Immaculate Conception In a Boa Constrictor 478

crudmonkey writes "Researchers have discovered a biological shocker: female boa constrictors are capable of giving birth asexually. But the surprise doesn't end there. The study in Biology Letters found that boa babies produced through this asexual reproduction — also known as parthenogenesis — sport a chromosomal oddity that researchers thought was impossible in reptiles. While researchers admit that the female in the study may have been a genetic freak, they say the findings should press researchers to re-think reptile reproduction. Virgin birth among reptiles, especially primitive ones like boas, they argue may be far commoner than ever expected."

Why NASA's New Video Game Misses the Point 205

longacre writes "Erik Sofge trudges through NASA's latest free video game, which he finds tedious, uninspiring and misguided. Quoting: 'Moonbase Alpha is a demo, of sorts, for NASA's more ambitious upcoming game, Astronaut: Moon, Mars & Beyond, which will feature more destinations, and hopefully less welding. The European Space Agency is developing a similar game, set on the Jovian Moon, Europa. But Moonbase Alpha proves that as a recruiting campaign, or even as an educational tool, the astronaut simulation game is a lost cause. Unless NASA plans to veer into science fiction and populate its virtual moons, asteroids and planets with hostile species, it's hard to imagine why anyone would want to suffer through another minute of pretending to weld power cables back into place, while thousands of miles away, the most advanced explorers ever built are hurtling toward asteroids and dwarf planets and into the heart of the sun. Even if it was possible to build an astronaut game that's both exciting and realistic, why bother? It will be more than a decade before humans even attempt another trip outside of Earth's orbit. If NASA wants to inspire the next generation of astronauts and engineers, its games should focus on the real winners of the space race — the robots.'"

The Perfect Way To Slice a Pizza 282

from the equal-distribution-of-the-pie dept.
iamapizza writes "New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article; 'The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if two people take turns to take neighboring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?' This is useful, of course, if you're familiar with the concept of 'sharing' a pizza."

New Nanotech Fabric Never Gets Wet 231

holy_calamity writes "New Scientist reports on a simple coating for polyester that renders it unwettable — even after two months underwater it emerges dry to the touch. Water cannot attach to the new fabric thanks to nanostructured filaments and a structure that traps a constant air layer. One potential use is for low-drag swim wear."

james writes "What do you get when you combine a MSI Wind U100 notebook with liquid nitrogen? The new Intel Atom frequency World Record ... and some damn cool pictures! A large copper pot is used, sitting on top of the GPU and chipset, and cold transfer through the original heatsink plate to the CPU. This was cooled down to about -20 C to achieve the new world mark. (Intel Atom N270 @ 2315mhz) For more information you can check out the original forum thread.
