Large Hadron Collider schedules holiday for 2012, full 7 TeV power for 2013
It's good to know that even huge inanimate objects appreciate the need for a work-life balance. After a nice winter hiatus, Switzerland's Large Hadron Collider is coming back online soon, set to resume smashing protonic beams at one another with the force of 3.5 trillion electron-volts (TeV) per beam, or 7 TeV in total. We have to swallow hard when we hear such force described as "low-energy," but that's what the LHC designers consider it, and moreover we're learning they'll skip past the middle and go for the full 14 TeV potential smashes after a retooling break during 2012. Although this may delay the discovery of the Higgs boson particle, other physics research shouldn't be stalled in the meantime -- scientists claim they'll be able to extract data from the low-energy collisions that could lend us more information on aspects of string theory, extra dimensions, and supersymmetry. Doesn't all this sound like nerds trying to avoid getting real jobs?
Balancing realistic physics with fun in Black Prophecy
The latest info about the sci-fi MMO Black Prophecy, currently in development at Reakktor Media, comes in the form of a series of dev blogs from the game's Technical Director, Cyrus Preuss. As with his two previous blogs, Cyrus gets down into the nuts and bolts of how the game's physics work, which may be of interest to those who'd like to know more about the underlying systems that will govern Black Prophecy's space combat. His rather technical dev blog is all about interaction with the physics engine. It especially deals with balancing the realism that some players want with the need to throw aspects of that realism to the wind, in favor of game mechanics that are simply more fun. He also discusses how the physics engine will relate to space stations, capital ships, and weapon physics. Black Prophecy fans interested in this kind of a look at the game can read all about it in "Interaction with the Physics Engine" on the game's official site.
Blizzard developers to speak at GDC 2010
Following the pattern held in previous years, Blizzard will again be loaning out some of their top developers for panels at this year's Game Developer's Conference in San Francisco, CA. WoW's former Lead Producer Jeff Kaplan, a.k.a. Tigole, presented the keynote speech at last year's GDC, and this year two top developers will be on tap to give horribly esoteric panels. Brian Schwab, Blizzard's Senior AI/Gameplay Engineer, will be presenting a lecture on AI architecture ... "AI programmers rarely use a pure architecture such as a State Machine, Planner, or Behavior Tree in isolation. Rather, several symbiotic architectures are mashed together, resulting in an overall architecture that is unique and powerful in its own way. This lecture is designed as a series of three mini-lectures where you will hear about several mashed up AI architectures along with intriguing lessons and insights." ... and Erin Catto, Blizzard's Principle Software Engineer, will be presenting a workshop on physics engines. "This one-day tutorial continues the 10-year tradition of the Math for Programmers and Physics for Programmers tutorials by bringing together some of the best presenters in gaming physics. Over the course of a day they will get programmers up to speed in the latest techniques and deepen their knowledge in the topic of physical simulation." More information, including panel times and availability, can be seen on BlizzPlanet's writeup of the announcement. This is basically total nerd talk -- it's very unlikely that we'll have any new WoW-related info from these panels, unlike Kaplan's keynote, but anything is possible. We'll keep you posted.
Black Prophecy technical director on game's physics
Black Prophecy from Reakktor Media is a sci-fi MMO that may ultimately be a bit more accessible to some gamers than reigning sci-fi champ EVE Online. It will be a very different sort of game than EVE, though. In fact, there is still much about Black Prophecy that has yet to be revealed, but the title's certainly got potential from what we've learned so far. While we're hoping to have more information for you about Black Prophecy in the coming months, the team at Reakktor Media is keeping fans up to date with dev diaries explaining some of the different facets of the game. The latest series of these blogs on the game's physics is being written by Black Prophecy's Technical Director Cyrus Preuss, which he continues today by focusing on the physics engine itself. His dev diary is a bit technical, but not all that difficult to follow either. Cyrus explains the concepts of the "physics loop" and the factors which ultimately define the game environment in space. (This includes collision detection, which triggers particle effects and sound effects, but there's quite a bit more to it than that.) If you're curious about this aspect of Black Prophecy's game design, have a look at Cyrus's dev diary or jump into the discussion by the fans on the game's official forums.
Large Hadron Collider grinds to a halt... again
In an increasingly unsurprising turn of events, the Large Hadron Collider suffered a major power failure this morning, knocking the machine and its website out of service. The failure occurred in an 18,000-volt power line in Meyrin, Geneva where the LHC is housed beneath the ground, causing pretty much everything to shut down. The LHC's magnets maintained a temperature of 1.9 degrees above absolute zero (having to re-cool them would have been a pretty sizeable setback), however, and no long-term damage seems to have occurred. The trouble-prone Large Hadron Collider is expected to resume full operations sometime later today, and is currently operating on limited power from a backup supply. Regardless, the unfortunate event is sure to resurrect that zany Higgs boson time-travelling theory.
Black Prophecy dev diary gives peek at game's physics
Now that the sci-fi MMO Black Prophecy is free to keep moving forward, the game's developer Reakktor Media is revealing more about the title. Recent dev diaries focused on Black Prophecy's art direction but now Technical Director Cyrus Preuss is kicking off a short series on the game's physics. The physics in any game can be important, perhaps moreso in a space-based MMO where players can move about in any direction and potentially interact (and collide) with many other ships in a single area. Cyrus boils a complex subject down to some easily understood explanations of how game physics work in the first installment, and will explore more on the topic in the coming weeks. He writes, "But you don't need to be afraid that I will confront you with highly complex equations or formulas. With this diary I also want to provide a look behind the scenes to those who didn't take the advanced physics or mathematics courses in school." Fans of Black Prophecy or those curious about the underlying game physics in an MMO can follow along with Cyrus' dev diary on the official game site.
Might Higgs boson be a time-traveling ne'er do well out to destroy the LHC?
We've certainly seen our fair share of crackpot theories regarding the Large Hadron Collider, and quite frankly the whole thing is becoming rather old hat. That said, when the New York Times comes up with something as far out as this, we most certainly have to share it with you. It seems that way back in July, 2007 two theoretical physicists (Danish string theory pioneer Holger Bech Nielsen and the Japanese physicist Masao Ninomiya), proposed an unlikely explanation as to why the LHC and the Superconducting Supercollider before it seem to be particularly accident prone. According to science writer Dennis Overbye, the Higgs boson (which the collider has been designed to observe) "might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather." Makes sense, right? Of course, we don't have any idea how these elementary particles might actually conduct the business of destroying equipment, but that hasn't stopped the duo from proposing a novel way to test this theory. According to a paper published earlier this month, a simple deck of cards could be made, either out of construction paper or, if you're feeling high tech, simulated on a computer. The deck would have one card indicating that the LHC should be shut down, and a much larger number of cards (maybe 100 million or so) that indicate that everything is good to go. If you draw the death card, as it were, you can bet that the shadowy hand of the Higgs boson is stretching back in time, telling you to halt the operation. Between all this and the proposed hyperdrive propulsion tests we came across a couple days ago, things are starting to get very Philip K. Dick over at CERN. Can we make one suggestion? Instead of a random number generator, why not Tarot cards? Or a Ouija board? You know, go for a Halloween vibe. [Via New Scientist]
Physicist wants to test Hyperdrive Propulsion in Large Hadron Collider
How come news can never come out of the Large Hadron Collider that doesn't remind us of our planet's impending SciFi Techno-Apocalypse(tm)? When not busy being called a doomsday machine, being bedeviled by hackers and Chuck Norris (yuck!), or just plain failing, the facility could be used to test "hyperdrive" spacecraft propulsion. Seriously! And you know what that means -- someone is planning on escaping the planet, and fast. A physicist named Franklin Felber has been musing over a little known German paper from the 1920s ("The Foundations of Physics" by David Hilbert) which states, in part, that under certain conditions a stationary mass should repel a relativistic particle. If this is true, Felber, concludes, then shouldn't a relativistic particle repel a stationary mass? According to MIT's Technology Review, the LHC would be the perfect place to test this idea: Felber could "set up a test mass next to the beam line and measure the forces on it as the particles whiz past." The experiment could be run in tandem with the collider's other work -- and who knows? Mankind may soon be on its way to the stars at near-light speeds. Let's just hope we figure this out before the robots take over. [Via Technology Review]
Fall Over: A platformer for gentlemen
Fall Over is a gentleman's platformer, with a twist. Combining a familiar-looking 2D landscape and real-life physics, indie developer Arvi "Hempuli" Teikari has put just enough spin on the genre to combat our rampant attention-deficit disorder. Fall Over is a simple concept; as a fancy-suited gentleman, reach the end of the level with as many coins in your pocket as possible. The challenge is working with the game's real-world physics, including the little things we take for granted -- like accidentally knocking your character on his back after hitting his head on a platform above -- and keeping your coins safely tucked away. It's the engine that would make Mario scream, and it's a free game worth a few minutes of your time. Make sure to grab your top hat and monocle before checking it out. [Via BigDownload]
Large Hadron Collider restart, end of the world pushed back to mid-November
Still undecided about what to do with those precious few months before the biggest doomsday since Y2K? Then you're in luck, 'cause the much anticipated / feared restart of the Large Hadron Collider has now been delayed yet again, almost exactly a month after the last delay. This time it looks like a couple of vacuum leaks are the culprit, and CERN says that the collider is now unlikely to restart before mid-November, which just so happens to coincide with the peak of the Leonids meteor shower. Coincidence? Yes, yes it is.
Acoustic superlens could mask ships from sonar... in theory, anyway
Man, the mad scientists are really on a roll of late. First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.[Via Slashdot]
AlloSphere three story virtual environment not available for birthday parties, Bat Mitzvahs
Researchers at UC Santa Barbara are developing an immense, wholly immersive VR environment that would allow groups of researchers the opportunity to explore their data aurally and visually on a scale never before seen. The AlloSphere is a three story metal sphere housed in an echo-free chamber, large enough that twenty researchers can stand on a bridge and take a walk through an atom, for instance, or a human brain. The project relies on a supercomputer for generating real-time, high-res 3D video and audio streams from a mountain of scientific data, and currently the team is hard at work building the bad boy's computing platform and interactive display. The project leader JoAnn Kuchera-Morin has yet to state whether or not the sense of smell would be incorporated into the finished product, but we sure hope not -- that would be rather distracting, don't you think? Check it out on video after the break.[Via TED]
Sway releases a free version
If you haven't yet tried Sway, the game from Illusion Labs and ReadyFireAim, now's the perfect time to do so. They've released a free version of the game that limits you to three levels and just two characters, but it's enough to try out the really unique control scheme. Back when I first posted about the game, I hadn't tried it yet, but it's now been on my iPhone for about a month, and it's excellent. Each of your thumbs is a "hand" on your characters (i.e., to grab something with your left hand, in game, you just touch your thumb to the left side of the screen), and then once you've grabbed something, you can swipe that thumb back and forth to sway the character around. It gets pretty complex, but practice makes perfect, and a few stages in, you'll be swinging from grip to grip with the greatest of ease.The full version still costs $4.99, and if you enjoy the free version, I highly recommend it: there are many more characters that you can pick up and choose from, and the stages actually get really tough, as there's a lot of precise swinging that you'll have to do to explore the whole area and find everything there is to find. Sway might be a sleeper hit for the iPhone -- it took me a little while to figure it all out, but once I did, I found a control scheme that's delightfully original. If you haven't tried it out yet, definitely take advantage of the free version.
GDC09: Havok gets smart, announces Havok AI
Havok is exploding like a red barrel into the world of artificial intelligence. With ragdoll grace, the middleware company announced its new Havok AI SDK during GDC 2009, promising "unique solutions" to various AI pathfinding issues faced by today's game developers. Like the folks at 1UP, we're not exactly sure what this means for gamers, though the new software is supposed to be fully compatible with Havok's other products and tools, such as Havok Physics. Perhaps now enemy patrols will get the good sense not to seek shelter behind things that go kablooey when bullets begin to fly.[Thanks David B.]
NVIDIA licenses PhysX technology for Sony's PlayStation 3
After being on the tip of gamers' tongues last summer, NVIDIA's PhysX technology has cooled a bit in terms of sheer popularity. That said, we've no doubt that the buzz will be back in force after this one clears the airwaves. NVIDIA has just announced that it has nailed down a tools and middleware license agreement for Sony's PlayStation 3, effectively bringing the aforesaid physics tech to what's arguably the most potent game console on the market today. As a result of the deal, a PhysX software development kit (SDK) is now available to registered PS3 developers as a free download for use on the SCEI Developer Network. What exactly this means for future PS3 games remains to be seen, but one's things for sure: it's only up from here.
Zen Bound arrives on the iPhone
This one's impressive -- Zen Bound originally started out as Zen Bondage, a physics game/sandbox where the goal was to wrap a rope around a 3D shape or object. The game has just recently been ported to the iPhone, and in the process has actually been improved -- the graphics look sharper and the iPhone's multitouch controls really add to the tactile experience. As a "game," it might be questionable -- it looks like there's a lot of fudging in terms of whether or not the rope has "covered" the object, and the scoring system itself is more or less tossed in as just a reason to get you to interact with the objects. But as an app, and a demonstration of the kinds of interactivity that can be exclusive to a device like the iPhone, it comes highly recommended. Zen Bound is available on the App Store now for $4.99.
WoW in 3D doesn't work so well
3D seems to be making a reemergence lately -- there was a 3D commercial on the Super Bowl last week, I'm going to see Coraline in 3D this weekend (Neil Gaiman and stop motion for the win), and Nvidia's 3D Vision cards have recently been integrated with World of Warcraft. But not so fast there: apparently while the system does make WoW stereoscopic (sends a different picture to each eye), and while it does work for some media (apparently watching 3D HD content with the system "feels like your monitor is a window"), analyst Rob Enderle over at TG Daily says WoW in 3D isn't all that amazing.Let's not forget, of course, that this is a game going on four years old, and while it has a terrific art style, and has recieved multiple graphic updates since then, we're still dealing with old technology in terms of a graphic engine. So Enderle says that the 3D really makes you realize that there are no real physics in the game -- "the objects," he says, "look like flat cutouts fanned out in a 3D field." The physical limitations are there, too -- you need a special monitor, apparently, and it's only 22" big, which might seem fine for most, but anyone who works all day on a computer (like yours truly), is used to a little bigger screen.Not to mention that, as he says, any technology that requires you to wear glasses isn't quite as cool as it could be yet. But 3D is obviously making progress, and the more popular it gets, the easier it'll be to make and experience. Maybe someday we'll all see Azeroth as a 3D world around us.
Crayon Physics Deluxe for iPhone
Crayon Physics Deluxe (App Store) is an iPod Touch/iPhone 2.0 game highly similar to Touch Physics (App Store) in that you must move a ball to the goal (represented by the star on the right) by drawing various things on the screen. For instance, to move a ball across a gap, you would simply draw a line with your finger over the gap.The game has 50 levels, and it includes a level editor so that you can make your own levels to increase replay value. You can play straight through the levels, or use the level chooser to jump around and play any levels (useful if you get stuck on a particular level). The music is calming and the graphics are good, but the levels initially draw very slowly.
World's largest computing grid lives to go live
Contrary to popular belief, the world as we know it didn't implode after the Large Hadron Collider was flipped on. Sure -- someone, somewhere is growing a ninth arm and trying desperately to land a cameo on Fringe, but the planet at large is still humming along just fine. Now, the world's most ginormous computing grid (the Worldwide LHC Computing Grid, or WLCG) has gone live, and the gurus behind it are celebrating the beginning of its momentous data challenge: to analyze and manage over 15 million gigabytes of data each year. The Grid combines the IT power of over 140 computer centers, 100,000 processors and the collaborative efforts of 33 countries. Unfortunately, there's no word on when the official WLCG-based Call of Duty 4 server will be green-lit for action, but we hear it's pretty high on the priorities list.[Via China View]
Toy with science in WiiPhysics
If, like us, you spent hours gawking at Pocket Physics on the DS (or Crayon Physics, its predecessor on the PC), you'll know that it's one of the most time-consuming homebrew titles on the handheld. Sooner or later, it was inevitable that the homebrew community would spawn a Wii version, and homebrewer Beardface has answered the call with WiiPhysics. The video above is version 2.1 of the title, though it has since enjoyed a slight update, adding a two-player mode. Download it here![Via GBAtemp] The homebrew community is doing nifty things with the Wii. Have you learned how to play DVDs on your console yet? Or read about the app that lets you play games from other regions? What about getting Goldeneye to run on Wii? Alternatively, you could just use homebrew to get your cheat on.
