A group of physicists at Massachusetts Institute of Technology (MIT) has released a new study that involves lasers and a cloud of lithium atoms going dark as part of the Pauli blocking theory. This is the first observation of Pauli blocking's effect as it relates to how atoms scatter light. When one thinks of... Read more...
During yesterday’s Google I/O event, we heard about several updates to Google software products, including Android 12 and Wear OS. Google also managed to bring in actor Michael Peña to tour the new Google quantum computing and AI campus. Today, we get to take a closer look at it so let us dive right in… Google’s... Read more...
The concept of Time travel often comes up in a multitude of pop culture references, and it gets rather confusing with all the interpretations. If you begin to think about it, paradoxes and loopholes plague our understanding of how it all should work too. After all, it's science fiction is it not?  Based on the math of... Read more...
At this point, it seems inevitable that whenever NVIDIA reveals a new GeForce series, the company will have a number of cool tech demos on-hand to help sell us on what it can do, and tease us on what's coming to gaming. Unfortunately, many of these tech demos remain internal at NVIDIA, but there is the odd one that... Read more...
Videogames often get a bad rap for rotting our brains, creating violence or simply wasting our time, but as anyone with a sensible mind undoubtedly knows, there's a lot of good to come from them as well. A perfect example comes to us this weekend from Google's quantum AI lab team. It involves Minecraft and a whole lot... Read more...
If you possess the unique combination of characteristics that allow you be both incredibly precise and focused on specific physics problems yet daydreamy enough to stare up at the night sky and wonder “What if?”, you might work for NASA, and you might also be Harold G. White, a NASA physicist who’s... Read more...
Faster than the speed of light? Normally we think of The Flash, Superman, or perhaps a Federation starship using warp drive. In other words, we think science fiction or comic books. After all, surpassing that speed would overturn one of the fundamental laws of physics, Einstein's theory of relativity, often simply known by the equation E =... Read more...
A few months back, NVIDIA demoed its upcoming quad-core SoC for future tablets and related mobile devices, dubbed Kal-El. At the time, NVIDIA claimed that Kal-El would deliver 5x the performance of current Tegra 2 solutions and ship with a 12-core GeForce GPU as well. And now, NVIDIA is showing off Kal-El again, but...

When it comes to hardware-accelerated PhysX and the future of GPGPU computing AMD and NVIDIA are the modern-day descendents of the Hatfields and McCoys. Both companies attended GDC last week, where a completely predictable war broke out over PhysX, physics, developer payoffs, and gamer interest in PhysX (or the lack... Read more...
As death threats preceded the startup of the Large Hadron Collider (LHC) last year, one might not be surprised at foul play as testing is performed prior to the restart of the LHC. But fowl play? The LHC has been out of action for over a year, due to a helium leak that caused it to be shut down on September 19th of last year, nine days after... Read more...
AMD Demonstrates Optimized Executions of Havok Middleware on AMD platforms – Balanced Platform of CPU + GPU Processing Delivers Optimal Game Experience – SAN FRANCISCO, Calif. - March 26, 2009 - Advanced Micro Devices, Inc. (NYSE: AMD) and Havok, the premier provider of interactive software for physics simulation and content development,... Read more...
I know you slept through quantum physics class. Your snoring woke me up. Luckily, Someone at Magiq Technologies, among other people, was sitting up straight and taking notes. And they think they can make the next generation of data encryption essentially impregnable by using those pesky photons from page 234 in the textbook we didn't read... Read more...
DailyTech also has managed to uncover news regarding NVIDIA's upcoming Quantum Physics Engine. Slated to be released alongside the G80 GPU, NVIDIA will be announcing a new dedicated layer on the GPU which will be reserved for physics processing and be referenced as the "Quantum Physics Engine". Essentially, this new engine will... Read more...
Confused about effects physics vs. gameplay physics? [H] has asked ATI, NVIDIA, Havok, and Ageia about the two. They received in-depth responses providing great detail regarding effects and gameplay physics, what they mean for gameplay, and current hardware physics abilities. "After digesting... Read more...
Scott from the Tech Report just sent word of a new article where he takes a look at Ageia's PhysX PPU.  In typical TR fashion, there's plenty of technical detail, but unfortunately there isn't much performance data due to the lack of software to support the device.  Here's our take on the PhysX PPU from a few...

ATI announced today their plans for "boundless gaming" which includes new hardware physics acceleration. To those interested in seeing how the ATI cards perform physics, Tweak Town has coverage of the ATI presentation at Computex, which demonstrated their "True-to-Life Gaming Reality". They also posted a short... Read more...
GamePC labs has a review posted this morning of BFG's AGEIA PhysX card. Lots of good information in this review, along with some some insightful opinions and commentary.  We've also taken a look at this card. For another reference point, you can read our article right here. "The problem is not the hardware. After seeing the demos,... Read more...
When Mountain View California start-up Ageia announced a new co-processor architecture for Desktop 3D Graphics that off-loaded the heavy burden physics places on the CPU-GPU rendering pipeline, the industry applauded what looked like the enabling of a new era of PC Gaming realism.  Of course, on paper and in PowerPoint, things always...

Without question, one of the hottest topics throughout the industry this year has been the advent of the discrete physics processor or "PPU" (Physics Processing Unit). Developed by a new startup company called Ageia, this new physics processor gives game developers the opportunity to create entirely new game-play characteristics... Read more...
FiringSquad has posted some interesting comments from Havok concerning the physics in Ghost Recon: Advanced Warfighter and how it relates to Ageia's new physics card. Havok does not seem to be pulling any punches as they claim that the use of Ageia's discrete PPU does not offer any significant visual differences and typically... Read more...
With all the recent news of AGEIA's PhysX chip floating around, ATI doesn't want you to forget about their processing power. As PC Perspective tells us, there's "a ton of new and interesting information" in their latest article. "First, the R580 has a tremendous amount of floating... Read more...
