Comment Re:12 pages!?! (Score 1) 168

Most slashdotters would be running ad blocking software anyway. I know I am. I'd also never buy something based on seeing it in a banner ad.

On the other hand, I'd actually think about buying iRacer, watching Top Gear, or buying the magazine after reading this interesting article. That's how the web is meant to be used.

Comment Re:Finally (Score 3, Insightful) 1260

If pressed, many logicians will admit that the modern foundation of mathematics (ZFC) is probably inconsistent.
See this article:
http://www.math.princeton.edu/~nelson/papers/warn.pdf

The author discusses an informal survey he took among loogicians on page three.

If someone ever discovers a paradox, we can simply scale back to some other system and keep most of what we know, but still...

Sorry for replying to my own post, but I guess I meant any non-supercomputer. Apparently they've managed to get clusters to play at amateur Dan level over the last couple of years.

For the record, the go ranking system works out as

30 Kyu ... 1 kyu 1 dan amateur ... 5 dan amateur european ... 9 dan amateur european

5 dan amateur european is about equal to 1 dan professional, due to inconsistencies in rankings between countries.

Ugh. What's with perpetuating this nonsense? A computer did not beat the top ranked Western chess player. Rather, a group of people _reprogrammed the computer after each match_ to beat the top ranked Western chess player.

TFA, it is annoyingly vague on an important point: What is the rank of the Japanese player that lost?

And as others have pointed out, let see a computer take down a top ranked (10th Dan) player at Go. The best a machine has done (I think) is winning against a 5th Dan.

That's only on a 9x9 board. A competent low Kyu or Dan player could crush any computer on a 19x19 board.

For people who don't play go: the difference between 9x9 and 19x19 is a bit like the difference between ping-pong and tennis.

Deleting Certain Gene Makes Mice Smarter 259

An anonymous reader writes "Deleting a certain gene in mice can make them smarter by unlocking a mysterious region of the brain considered to be relatively inflexible, scientists at Emory University School of Medicine have found. Mice with a disabled RGS14 gene are able to remember objects they'd explored and learn to navigate mazes better than regular mice, suggesting that RGS14's presence limits some forms of learning and memory."

Comment Elastic cloaking (Score 1) 115

Cloaking uses metamaterials which have a negative refractive index- these bend light rays around the object being cloaked. Very recently, physicists and engineers realised that a similar principle can be applied to pressure waves caused by earthquakes. With the right design, the shockwaves might be bent around a building, rendering it "invisible" to an earthquake.

This was previously thought impossible due to mistakes in some engineering research articles.

More techncial articles can be found by googling "elastic cloaking".
