+ - LHCb confirms existence of exotic hadrons->

Submitted by Anonymous Coward
An anonymous reader writes "The Large Hadron Collider beauty (LHCb) collaboration today announced results that confirm the existence of exotic hadrons – a type of matter that cannot be classified within the traditional quark model. Hadrons are subatomic particles that can take part in the strong interaction – the force that binds protons inside the nuclei of atoms. Physicists have theorized since the 1960s, and ample experimental evidence since has confirmed, that hadrons are made up of quarks and antiquarks that determine their properties. A subset of hadrons, called mesons, is formed from quark-antiquark pairs, while the rest – baryons – are made up of three quarks. ... The Belle Collaboration reported the first evidence for the Z(4430) in 2008. They found a tantalizing peak in the mass distribution of particles that result from the decays of B mesons. Belle later confirmed the existence of the Z(4430) with a significance of 5.2 sigma on the scale that particle physicists use to describe the certainty of a result.
LHCb reports a more detailed measurement of the Z(4430) that confirms that it is unambiguously a particle, and a long-sought exotic hadron at that. They analysed more than 25,000 decays of B mesons selected from data from 180 trillion (180 ×10^12) proton-proton collisions in the Large Hadron Collider."

You cannot compare FM Radio's free Music service over Paid Broadband. FM Radio is still a bliss for countries where electricity outages takes place regularly, although this does not seem to be a reason in UK, but i doubt it and those who listen to FM would fight this till the end. Those who are planning this seem not to have heard FM radio and therefore they do not know how much joy it gives. This also can be a step to compel people to pay for Music instead of listening it free, which i do alot.

You wrote: "Having at last" Means a lot of work before you got it working, only satisfactorily, for your own self. It would be same for each person you deploy for. Unfortunately the lesson is only learned after you have tried for yourself. In the end it gets clear that Linux is not ready for non-techies.

A History of 3D Cards From Voodoo To GeForce 320

Ant sends us to Maximum PC for an account of the history and current state of 3D video cards (single print page). "Try to imagine where 3D gaming would be today if not for the graphics processing unit, or GPU. Without it, you wouldn't be [trudging] through the jungles of Crysis in all its visual splendor, nor would you be fending off endless hordes of fast-moving zombies at high resolutions. For that to happen, it takes a highly specialized chip designed for parallel processing to pull off the kinds of games you see today... Going forward, GPU makers will try to extend the reliance on videocards to also include physics processing, video encoding/decoding, and other tasks that [were] once handled by the CPU. It's pretty amazing when you think about how far graphics technology has come. To help you do that, we're going to take a look back at every major GPU release since the infancy of 3D graphics. Join us as we travel back in time and relive releases like 3dfx's Voodoo3 and S3's ViRGE lineup. This is one nostalgic ride you don't want to miss!"

Google Earth As a Game Engine For Ship Simulation 84

dinther writes "Yesterday the program Ships was released. Ships is significant because it is the first serious application that uses Google Earth as a game engine. In Ships, you take control of a selection of ships and drive them around the world (if you have that much time). Building games around Google Earth is now viable, thanks to its ever-increasing level of detail. From a technical standpoint, the Google Earth browser plugin has proven to be quite a capable platform to work with. Further tech details about the application are available as well."

Five Nvidia CUDA-Enabled Apps Tested 134

crazipper writes "Much fuss has been made about Nvidia's CUDA technology and its general-purpose computing potential. Now, in 2009, a steady stream of launches from third-party software developers sees CUDA gaining traction at the mainstream. Tom's Hardware takes five of the most interesting desktop apps with CUDA support and compares the speed-up yielded by a pair of mainstream GPUs versus a CPU-only. Not surprisingly, depending on the workload you throw at your GPU, you'll see results ranging from average to downright impressive."

Agreed. That old practice of formatting and reinstalling after some time is not sane now. Programs like ccleaner and Windows 2000 and later have made huge improvements over uptimes and stable intsallations. As far as memory, it may not be the culprit. The mobo can be the problem, even drivers for the mobo under Windows.

I gather it was past the darkness, mist and powerful keepers. I am not mixing up this with Thief. Both have an unreal connection. Oh wait unreal was also a game engine. Maybe now i am getting somewhere. Maybe i will get my hands on a copy when its out for taking!!!
