It's a representation of a reconstructed event passing through the detector... so roughly it represents the ~25 nano-seconds of time after the collision at the centre of the detector that generates the event.

Tut Tut   gotta remember the time of flight...


Eh?  Yes, in 25 nano-seconds a particle close to the speed of light can travel ~7.5 m,  which is ~enough for it to pass through the detector.  I'm including time of flight.  It's only an estimate, it's not like I made the image or anything...

i'm just saying it's not a snapshot in time...

I'm seeing it as a blurred movement/action photo.

 Two Thumbs  a photo with a shutter speed of ~25 ns, if you like.

Here's another one for you - two top-quarks being created and decaying Smiley  :




which bits are the top quarks?

You can't see them because they are so massive and unstable that they decay very quickly in the centre of the detector.

I don't know the specific details, but here is roughly what is going on:  The cyan-coloured lines are the reconstructed tracks of the event-decay products, the cylindrical yellow section represents the detector's calorimeters.  The magenta and blue bars represent energy deposits inside the calorimeters (leptonic and hadronic repectively)... so the biggest blue bars most likely represent the energy deposits in the hadron calorimeters from top-quark decay products, called b-quark jets.  Any cyan-coloured lines outside the yellow cylinder (with those red rectangles around them) represent muons being tracked through the outermost chambers of the detector; these will also likely be top-quark decay products, resulting from the W boson that is created when a top quark decays.

Hope that clears things up a little.  Smiley

one last question, is that a snap shot or a series of events over a period of time?

59  General / The Forum / Re: Speaker sand on: May 07, 2007, 23:24:37

floorstanders & decent speaker stands have compartments you can fill with sand to add extra weight & deaden any resonance.

Apparently using beach or builder's sand is no good as the moisture & salt can corrode the speaker/stand.

"Kiln-dried silver sand" is apparently what's required - anyone know where I can get some in Bristol?

Normal sand... rinse in water... dry in oven.  Job done.

69  General / The Forum / Re: Dishwashers and Washing machines on: April 27, 2007, 09:50:58
washing machines have connections for both hot and cold water and will only heat the water when there's no hot water,  would have thought that dishwashers are the same.

Okay so yeah, domestic hot water from a boiler should be a max of about 42C, they vary from about 30 to 45C, any higher than 40C and you risk scalding yourself if you hold you hand under the tap say.

I've never had a house where it wasn't possible not to scald yourself by holding your hand under the tap!  Goddamn cut and shut boilers/landlords/parents...

edit:  Arrgghgh, goddamn triple negative. I'm confused as to whether or not I said the right thing now  Doh! Smashed
70  General / The Forum / Re: Dishwashers and Washing machines on: April 27, 2007, 09:35:31

 as hot water from boilers is generally about 30C


I feel sorry for you - your "boiler" must really suck.  How on earth do you think central heating functions if the water comes out of the boiler barely above room temperature?!  In my experience radiators normally get too hot to touch, and that's after the water has been circulating through other radiators...

Yes, washing machines will make use of gas-heated hot water.  If the hot water is too hot for the temperature setting, it will be mixed with cold.  The water temperature will be maintained by a heating element though, which will also be used to get the water up to really high temps when needed.

It's not the washing machine/dishwasher that you really want to watch out for as far as white goods go - the fridge and freezer use way way more energy on average, especially in a busy house with lots of opening/closing of fridge doors.  And they really don't use any gas - well, unless you count the gas that might have been used in making the electricity...

If I was a parent I certainly wouldn't appreciate having to lead my kids through a minefield of gurning idiots who don't appreciate the fact that parks are there for EVERYONE's use.

The fact is that K & Gas are illegal, and i'm sure it would be a lot easier to explain to a 5 year-old why people are having a legal beer as opposed to filling their lungs with hippy crack.

And let's face it, if these crustafarians were really occupying the moral highground (rather than just pretending to with their morally-made clothing...), they wouldn't be in the park in the first place getting fucked up in front of everyone.  Maybe they'd be doing something useful instead...  Roll Eyes

To all the people saying that "Why not use this money to cure the world's problems", the answer is pretty obvious.  It's been shown many times over that money doesn't in general cure the world's problems. People themselves are the answer to curing the world's problems.  For example, you can chuck as much money as you like into a poverty-stricken country... granted it'll help a bit, but unless you can stop all the leeching corrupt motherfuckers at the top from taking a fat cut before passing it down, then what is the point?  Should we just totally give up on all this great science so we can - in many respects - throw money away?  I think not.

And Mr Gecko: As for all that Big Bang stuff you keep reading, that is basically bollocks.  There is a major major difference between a universe being born, and smashing some particles together.  Granted we might be able to replicate the environment in some way at some minuscule time after the Big Bang, but it is hardly the same thing.  Reporters just throw in the term Big Bang because it sounds sexy and everyone's heard of it...  Roll Eyes

CPU GPU, same as really. It al boils down to billions of logic gates how you  arrage them or where you plug them in is by the by.
The size thing means cheaper production costs. twice as many chips per slice.
also smaller chips means more speed.

As for GFLOPS,
 can you use all those GFLOPS in a commercially viable way...
It could just lead to really inefficient program design because of the surplus of power.

when you're offering toy story quality gfx rendered in real time you still need to build toy story to be rendered in the first place...

Hmm, I still don't see what all this has to do with what you were originally saying.  Technology always moves forward... Sony have outgunned Microsoft for now, then positions will inevitably reverse, and reverse again... The process size is just whatever's happening at the time.
99  General / The Forum / Re: PS3 Launch... on: March 27, 2007, 16:49:16

oh and the CELL is based on the 90nm manufacturing process whereas the latest gfx cards, most likely to end up in a future media centre (hopefully in an upgrade module format) are already at 46nm  NERD ALERT!


What's that got to do with anything?  The Cell isn't a gpu, it's a cpu.  I'd imagine that in 5 years Sony will release a slimline version of the PS3 that will utilise the smaller fabrication size, thus reducing power/heat consumption.    Plus all that you really care about anyway is the GFLOPs, and the cell processor has plenty of those.
