CERN Physicists Generate Hottest Man-Made Temperatures Ever: ~5.5 Trillion K

Diggester sends this quote from Nature News: "Physicists at CERN's Large Hadron Collider have achieved the hottest man-made temperatures ever, by colliding lead ions to momentarily create a quark gluon plasma, a subatomic soup and unique state of matter that is thought to have existed just moments after the Big Bang. The results come from the ALICE heavy-ion experiment — a lesser-known sibling to ATLAS and CMS, which produced the data that led to the announcement in July that the Higgs boson had been discovered. ALICE physicists, presenting on Monday at Quark Matter 2012 in Washington DC, say they have achieved a quark gluon plasma 38% hotter than a record 4 trillion degree plasma achieved in 2010 by a similar experiment at Brookhaven National Laboratory in New York, which had been anointed the Guinness record holder."

    Tell me the temperature in Celcius, I can't keep converting. :P

      Buddy, this is /.
      In here, Natalie Portman (aka HotGrits) is the unit of hotness.

      This is why they call it hottest Man-Made Temperature, rather than hottest Woman-Made.

      Indeed. The unit of hotness is the Helen.

      So then a millihelen would be the amount of hotness needed to launch one ship?

      If anything is published in a forum that also caters to Americans, you can safely assume that the short scale was used. While people elsewhere can convert, most Americans can't, whether this is due to ignorance, incompetence or hubris.

      The long system makes more logical sense:

      one billion = one million ^2
      one trillion = one million ^3
      one quadrillion = one million ^4

      As opposed to the short system:

      one billion = one thousand ^3
      one trillion = one thousand ^4
      one quadrillion = one thousand ^5

      I.e. the name versus the exponent is always off by one.

    Part of me thought that the story would at least involve Hot Pockets with a temperature range that high...

    Curious (and too lazy to google)-- At 5.5 trillion K, they aren't going to just stick a thermometer in there. How do they measure how hot the plasma was?

    Temperature is related to energy. So by measuring how much energy is in the quark-gluon plasma you can deduce its temperature.
    Another example is how do you determine the surface temperature of stars ? We sure as hell don't send thermometers to the sun, or to other stars. So how do we know that the surface temperature of the sun is roughly 6000 K ? You mesure how much energy the sun radiates, and by using a theoretical model (known as a black body) you can establish a relationship between amount of radiated energy and temperature. Therefore you can deduce the temperature of the sun (or of other stars).

  5. Zero Kevins by sexconker · · Score: 5, Funny

    My home town nearly went to zero Kevins back in 1978.

    It was a particularly cold winter, and we were already down to 3 Kevins (due to their low popularity at the time).

    Kevin Thomas had flown out to be with his son's family for a wedding and got stuck in Boston for a whole week due to the weather. 2 Kevins left.

    Kevin Lemmer was rushed to the hospital during my shift. I still remember the call from the EMTs as the ambulance was rushing toward us. "It's Lemmer. He's in bad shape. Drove right into the fucking ditch." We called the time of death at 6:15 PM.

    At 6:16, all eyes turned to room 2217. Kevin Spencer was 82 and on his death bed with leukemia. His family being Catholic, he had already been given his last writes. If he couldn't hold out until Kevin Thomas returned, we would be at zero Kevins. Sure, we had 4 perfectly healthy Calvins, but they're just not the same.

    It was 7:15 when Carla Brooks and her husband James burst through the main entrance. "She's not due for 2 weeks!", James exclaimed. As the staff bustled around getting the Brookses settled, they exchanged darting glances with each other. This was their first child, and they wanted to keep the baby's sex a secret. Of course, in a small town, secrets don't get kept. Nearly all of the hospital staff new that the child about to rip open Mrs. Brooks was indeed a boy.

    The delivery was routine, and Kevin Brooks was born healthy, if a tad underweight, at 10:52 PM. Kevin Spencer was pronounced dead at 10:54.

    It was, as they say, a close one. Kevin Thomas arrived two days later, the weather having finally cleared up. To this day, we still rib him about it.

    Cedar Falls is currently at 5 Kevins.
