    How much government money did they waste on this project?
    You could probably say that about any invention, you never know what they can bring forth.
    They once set out to create better light bulbs, the work they did led to quantum physics and nuclear energy.

    Lol no. I'd rather they spent their time trying to find the cure for AIDS than this bull. This **** ain't gonna benefit nobody...
    Oooooh yeahhhh 'absolute zero' how awesome lets publish our findings! But there are still millions dying -.-
    Typical fat, nerdy virgins with nothing better to do than leech off the government with their 'groundbreaking' research.

    **** THAT.

    Maybe there are different groups of scientists all doing different research every single day of the year to find out cures, interesting breakthroughs and things that can change the world we live in. It does not mean that every ****ing scientist has to specialise into aids research. Maybe some physicists haven't got the skills to find cures for aids or don't actually find that area appealing, people who are good at different things specialise into different areas. I wish you paid attention in microeconomics.

    I know, right? Isaac Newton was a waste of space, it's not like classical mechanics has helped put Man on the Moon.

    If everyone took the same attitude towards science as you do then most of the commodities we take for granted would never have been invented.

    Stfu and read it, you can't explain quantum physics in a sentence.

    This kind of research is used to make faster computers. Like the one you're using now, so if you care that much, sell your computer and give the money to oxfam.

    I find physics is like jazz. People said jazz was dead and people said physics was dead, yet every time something new comes out in both disciplines that proves them all wrong. By 'dead' I mean 'not much else to discover (or play) just some loose ends to tie up'

    It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time1. Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery.

    Lord Kelvin defined the absolute temperature scale in the mid-1800s in such a way that nothing could be colder than absolute zero. Physicists later realized that the absolute temperature of a gas is related to the average energy of its particles. Absolute zero corresponds to the theoretical state in which particles have no energy at all, and higher temperatures correspond to higher average energies.

    However, by the 1950s, physicists working with more exotic systems began to realise that this isn't always true: Technically, you read off the temperature of a system from a graph that plots the probabilities of its particles being found with certain energies. Normally, most particles have average or near-average energies, with only a few particles zipping around at higher energies. In theory, if the situation is reversed, with more particles having higher, rather than lower, energies, the plot would flip over and the sign of the temperature would change from a positive to a negative absolute temperature, explains Ulrich Schneider, a physicist at the Ludwig Maximilian University in Munich, Germany.

    Schneider and his colleagues reached such sub-absolute-zero temperatures with an ultracold quantum gas made up of potassium atoms. Using lasers and magnetic fields, they kept the individual atoms in a lattice arrangement. At positive temperatures, the atoms repel, making the configuration stable. The team then quickly adjusted the magnetic fields, causing the atoms to attract rather than repel each other. “This suddenly shifts the atoms from their most stable, lowest-energy state to the highest possible energy state, before they can react,” says Schneider. “It’s like walking through a valley, then instantly finding yourself on the mountain peak.”

    At positive temperatures, such a reversal would be unstable and the atoms would collapse inwards. But the team also adjusted the trapping laser field to make it more energetically favourable for the atoms to stick in their positions. This result, described today in Science1, marks the gas’s transition from just above absolute zero to a few billionths of a Kelvin below absolute zero.

    Wolfgang Ketterle, a physicist and Nobel laureate at the Massachusetts Institute of Technology in Cambridge, who has previously demonstrated negative absolute temperatures in a magnetic system2, calls the latest work an “experimental tour de force”. Exotic high-energy states that are hard to generate in the laboratory at positive temperatures become stable at negative absolute temperatures — “as though you can stand a pyramid on its head and not worry about it toppling over,” he notes — and so such techniques can allow these states to be studied in detail. “This may be a way to create new forms of matter in the laboratory,” Ketterle adds.

    If built, such systems would behave in strange ways, says Achim Rosch, a theoretical physicist at the University of Cologne in Germany, who proposed the technique used by Schneider and his team3. For instance, Rosch and his colleagues have calculated that whereas clouds of atoms would normally be pulled downwards by gravity, if part of the cloud is at a negative absolute temperature, some atoms will move upwards, apparently defying gravity4.

    Another peculiarity of the sub-absolute-zero gas is that it mimics 'dark energy', the mysterious force that pushes the Universe to expand at an ever-faster rate against the inward pull of gravity. Schneider notes that the attractive atoms in the gas produced by the team also want to collapse inwards, but do not because the negative absolute temperature stabilises them. “It’s interesting that this weird feature pops up in the Universe and also in the lab,” he says. “This may be something that cosmologists should look at more closely.”
    Wow, that's pretty amazing!!!!

    I recommend you guys read this blog post by Michael de Podesta:
    http://protonsforbreakfast.wordpress...-do-not-exist/

    While 'negative temperatures' are still a good discovery, the applications for it (currently) are being over exaggerated. Maybe future developments will change that though.
    Aaaaaand there we have it.

    When I am a bit dubious about a scientific announcement more often than not I need just sit back and someone will put it in a more realistic context, or poopoo it entirely.

    I was going to neg you but I decided not to even bother. Your sig indicates that you are an obvious keyboard warrior looking for an online fight because no-one will bother with you in real life. If you are genuinely ignorant however then I will say this: Science has never been about solving the world's problems, that is the biggest misconception about science. Science is purely about understanding the world around us and because knowledge is power a lot of scientific research ends up being useful to solving problems but that was never it's original aim.

    No, 0 is most definately a real number.

    To be completely honest the ammount of spectacular awesomeness that could arise from research into Quantuim Computing, and exotic matter , makes this kind of a very good investment.

    Not everyone is a Biologist, not every-one can do the same thing, nor has the capabilities.

    I disagree. Some days science takes huge leaps. Most days it takes little steps.
