Richard Pritches writes in to let us know that MIT errata expert Evangelos Georgiadis has disproved 44 conjectures set by Dr. Stephen Wolfram (founder of Mathematica) in A New Kind of Science. The paper was published in the latest issue of the Journal of Cellular Automata and can be read in PDF form at Prof Edwin Clark's collection of reviews of Wolfram's ANKS. "The formulas provided by Wolfram for these [44] rules are not minimal. Moreover for 8 of these cannot be minimal even by simple inspection since minimal formula sizes for 3-input Boolean functions over this basis never exceeds 5."

It's that time of year again. Last year's response to our Game of the Year post was so enthusiastic that I thought it would be worthwhile to give it another go. So, once again, some of the Slashdot folks have come together to offer up our 'games of the year'. Scuttlemonkey, Scott Collins, Chris Brown, CmdrTaco, and myself have all put together quick blurbs about the games we couldn't get enough of this year. When you're through reading those, it's your turn to speak up. What was the game you couldn't put down? The next-gen consoles really came into their own this year; was it one of those games, or something for the PC? In your opinion, what was the best game of the year?

StonyandCher has passed us a link to PCWorld.au, once again raising the tough topic of work/life separation. A department of the Australian government went ahead with a purchase of dozens of Blackberry communication devices, but is now delaying their deployment. The reason: "Staff expressed fears about BlackBerries contributing to a longer working day and felt it was going a step too far because mobile phones are adequate for out-of-office contact. Not everyone agreed, however, with some senior executives claiming a BlackBerry can contribute to work/life balance by facilitating telecommuting and more flexible schedules. " For the time being this issue is on hold for those staffers, but how does this issue fall for you? Is constant accessibility freeing or just another chain around your neck?

MrCrassic writes "There are talks floating around surrounding Google's possible talks with Verizon and possibly T-Mobile to establish an agreement for the carrier to deliver phones carrying Google's speculated mobile operating system. According to the article, one of the main hurdles slowing down the product are concerns about user privacy and advertising, one of Google's well-renowned strengths. With over 6 million customers potentially at their disposal, could this be "the deal" that establishes Google's hegemony in the internet sphere?"

Fishbat writes "In a cutting message to the Foundations of Mathematics mailing list, Stanford's Vaughan Pratt has pointed out an elementary mistake in the recently announced proof that Wolfram's (2,3) machine is universal." Update: 10/30 04:18 GMT by KD : Ed Pegg Jr. from Wolfram Research points to this response to Dr. Pratt's note, which has been submitted to the FoM mailing list but has not yet appeared there due to moderation.

Rik702 writes "Wolframscience.com have announced that an undergraduate from Birmingham, UK has proved Wolfram's 2,3 Turing Machine is universal." You can read a pdf of the proof as well as some related coverage.

eldavojohn writes "A fairly large breakthrough took place earlier this month with the most powerful man-made antimatter electron beam ever being created at North Carolina State University. Professor Hawari who worked on the project explains its benefits: 'The idea here is that if we create this intense beam of antimatter electrons — the complete opposite of the electron, basically — we can then use them in investigating and understanding the new types of materials being used in many applications.'"

simoniker writes "Are MMO populations 'tribal', and if so, what's the next tribal shift after World of Warcraft? At Gamasutra, academics including MIT's Henry Jenkins and Ludium's Edward Castronova discuss what's next for the MMO market, based on their research and play patterns. Jenkins states that WoW is getting _too_ much analysis from researchers right now: 'WoW deserves attention because it has so captured the imagination of gamers over the past few years. That said, I don't think it is healthy for the field of games studies, which is still emerging, to be so fixated on a single game franchise — no matter what the franchise. A few years ago, it might have been The Sims or GTA, now it's WoW.'" For more on this topic MMOG industry veteran Gordon Walton spoke on this topic last week at GDC Austin, and notes from that event are also available at Gamasutra.

oDDmON oUT writes "While your mother may have told you that sitting too close to the TV was bad for your eyes, the folks over at New Scientist are reporting that too much television may be linked to a bad attention span 'The study is not proof that TV viewing causes attention problems, Landhuis notes, because it may be that children prone to attention problems may be drawn to watching television. "However, our results show that the net effect of television seems to be adverse."'"

ObsessiveMathsFreak writes "I'm an applied mathematician who has recently needed to obtain good numerical approximations to the classic second-order wave equation, preferably in three space dimensions. A lot of googling has not revealed much on what I had assumed would be a well-studied problem. Most of the standard numerical methods, finite difference/finite element methods, don't seem to work very well in the case of variable wave speed at different points in the domain, which is exactly the case that I need. Are any in this community working on numerically solving wave equation problems? What numerical methods do you use, and which programs do you find best suited to the task? How do you deal with stability issues, boundary/initial values, and other pitfalls? Are there different methods for electromagnetic wave problems? Finally, when the numbers have all been crunched, how do you visualize your hard-earned data?"

bheer writes "The Guardian points out a page on the Mozilla wiki noting that 'only 50% of the people downloading Firefox actually try it out, and only a further half of those continue to use it actively.' ZDNet has some commentary on the browser's retention rate. While a 25% retention rate isn't necessarily bad, Mozilla is trying to improve these figures with a 12 point plan that includes more TV and media advertising, a better start page and several installation tweaks."
