Comment Re:Temperature Measurement (Score 2, Informative) 570

It's between particles, regardless of their kind. At room temperature, atoms within molecules also participate in heat exchange; this is why for adiabatic compression of ideal gas you need to know if it has monoatomic, biatomic or bigger molecules - this affects the vibrational modes within the molecule. Again at room temperature, quantum physics prevents this exchange to continue inside the atoms - in non-metals, the atom-atom collisions happen below the energy that can knock electrons out of them, let alone affect their nuclei.

But here we're talking about many orders of magnitude above room temperature, and what used to happens to molecules and atoms inside them happens to quarks and gluons. The important thing is that in proton collisions, the particles don't stay together long enough to achieve thermal equilibrium, so it makes no sense to talk about thermodynamics. But with lead ions, if quark-gluon plasma formation in fact happens (gathering data needed to prove or disprove this is part of the experiment), the particles interact enough times that we can talk about temperatures, pressures and so on.

It's actually 0.1mJ (or 1138TeV) per collision (half that per ion). They have ways to go before hitting 1 cal. However, within the volume of a nucleus, that's still a crazy concentration of energy.

Also, a beam has a *lot* of ions (they're starting with 2e10/beam but I believe their goal is 100x that before the end of the month). That's 10MJ/beam before the end of the month, which is already a fairly serious amount of energy to have in a particle beam.

OK, Android user here. Time for some anecdotal evidence - take it with a grain of salt.

Slashdot comments is precisely the kind of webpage that's openly hostile to phone users. Phones, even those with usable browsers, suffer from slow CPUs, lack of RAM, small screens, and inability to JIT Javascript. Slashdot comment pages, on the other hand, are heavy on data, VERY heavy on Javascript, and are formatted with deep indentation that's painful to track on a mobile phone screen.

When I surf from mobile, I read Slashdot frontpage and linked articles (and I use Slashdot basic format even from my desktop). I also read web forums - most of those pages contain lots of text but aren't breaking the mobile browsers. However, most of my stuff is covered by specific clients - Facebook, Twitter and RSS readers are all running outside browsers. As a result, I rarely top 5MB in 1 session.

Comment Re:LHC can't contribute (Score 5, Informative) 304

Had you read the abstract, you'd know that Fermilab's result is b+anti-b decay, not p+anti-p, so LHC is fine as long as they can specifically track which muons came from b quark decays.

As a matter of fact, they have a special detector just for that (it's not general-purpose, because b+anti-b pairs decay within centimetres from their creation point, so they actually drop particle tracker 5mm from the beam). See LHCb experiment.

What if Ubisoft decides not run these online services in the future? Will my game stop working?
Ubisoft is committed to being a forerunner in providing new exciting online service. If any service is stopped, we will create a patch for the game so that the core game play will not be affected.

So will RELOADED.

Better idea - "To be eligible to donate funds to the election campaign of a person running for federal office, the donator must be a human individual, not a corporation, and must live within the district of the person to whom he is donating the funds."

Won't work. Think 'donation mediation service professional'.

He was refering to ATL. This is a basic example of ATL (Active Template Library), when used to define a COM object:
