Music By Natural Selection 164

maccallr writes "The DarwinTunes experiment needs you! Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet and we'd really appreciate some Slashdotter idle time. We recently upped the maximum 'genome size' and we think that the music is already benefiting from the change."

NYT's "Games To Avoid" an Ironic, Perfect Gamer Wish List 189

MojoKid writes "From October to December, the advertising departments of a thousand companies exhort children to beg, cajole, and guilt-trip their parents for all manner of inappropriate digital entertainment. As supposedly informed gatekeepers, we sadly earthbound Santas are reduced to scouring the back pages of gaming review sites and magazines, trying to evaluate whether the tot at home is ready for Big Bird's Egg Hunt or Bayonetta. Luckily, The New York Times is here to help. In a recent article provokingly titled 'Ten Games to Cross off Your Child's Gift List,' the NYT names its list of big bads — the video games so foul, so gruesome, so perverse that we'd recommend you buy them immediately — for yourself. Alternatively, if you need gift ideas for the surly, pale teenager in your home whose body contains more plastic then your average d20, this is the newspaper clipping to stuff in your pocket. In other words, if you need a list like this to understand what games to not stuff little Johnny's stocking with this holiday season, you've got larger issues you should concern yourself with. We'd suggest picking up an auto-shotty and taking a few rounds against the horde — it's a wonderful stress relief and you're probably going to need it."

Comment The wacky theory is testable (Score 1) 194

The guys who proposed the wacky theory did in fact suggest a test, and quite an interesting one. The critic who wrote TFA apparently missed it when he "skimmed" the papers he publicly ridiculed.

The idea is to conduct some random event, say 1,000 coin tosses, and pre-commit to cancel the LHC if we observe a ridiculous outcome, like 1,000 heads in a row.

Comment It is worth saying again (Score 3, Interesting) 232

Privacy is doomed. The march of technology can be slowed, but not stopped. Eventually this will give us a world without theft. The trick is keep it from also giving us a world without fun. That means getting rid of most of our laws, not just nibbling around the edges trying to make it hard to enforce them.

No, I don't know how to achieve that goal, short of re-wiring some brains.

Comment This is not an explanation (Score 2, Informative) 99

So solar output was correlated with sunspots. Now it is also correlated with a subsurface current. A step forward, but it is a bit premature to use the word "explain."

On a different not, how depressing that I have been pushed into resenting several forms of science. When I saw the headline, my first thought was, "Crap. More data to cherry pick to justify central control over individuals." And I say this as someone who has actually published in peer reviewed journals. Gloom.

Comment Explaining is not predicting (Score 3, Interesting) 348

The main criticism of string theory is that it is too flexible. It can be contorted to generate any prediction, so it predicts nothing. This problem is not unique to physics; I saw it in economics too. Add more parameters to your model and you can fit historical data better, but your predictions of the future get worse. TFA seems to be just a string of examples of contorting string theory to fit past experimental results.

I thought the essence of the 2-slit experiment was that you can detect quantum indeterminacy without measuring the quantum state, and hence without collapsing the waveform, by observing whether the various possible quantum states are interfering with each other. In the case of 2 slits, if you get fringes you have indeterminacy (particles are going through both slits) and if you get spots then the wavefunctions are collapsed (the particles have been forced to choose a slit). I assume there is an analogous test to see whether particles have been forced to choose their polarization. This seems to be all you need for instant transfer of the message "I have measured the polarization".

As I understand, the essence of teleportation is that collapsing the wavefunction of the first particle (by measuring it) instantly collapses the wavefunction of the second particle. What I don't understand is why this does not represent transmission of the information that the first particle has been measured. Is it not possible to test whether the second particle's wavefunction has been collapsed by, say, sending it through slits?
