Sparticles are also particles. They're particles which are predicted to exist in supersymmetry theories and they mathematically pair up with 'normal' particles like quarks, electrons, photons, etc. The supersymmetric fermions (spin-1/2) particles get a 's-' prefix so they're squarks and selectrions, the supersymmetric bosons (integral spin) particles get an '-ino' suffix instead of an '-on', so you get a photino, gluino, etc. There's good theoretical reason to believe in their existance apart from string theory because electroweak unification has been very successful in uniting the electromagnetic and weak forces, and supersymmetry is just an extension of those theories uniting the electroweak theory with the strong force. Sparticles also aren't even 'opposite' to particles in the sense that matter and antimatter are 'opposites' and annihilate each other (there should also be anti-sparticles, btw).

Branes are just a generalization of strings. Strings are 1-branes. A 2-brane would be a 2-dimensional fundamental object more like a piece of paper...

Wow. Most posts are hard for me to follow but this takes the cake. Did you find this on wikipedia?

No, sadly that's all from memory.

Incidentally the W+, W- and Z0 particles that mediate the electroweak force (and are responsible for readiactive decay) have supersymmetric partners just like photinos and gluinos, only they're called winos and zinos. The gravitino would be the supersymmetric partner to the graviton...

That's because you're a Stroke! :eyebrow:
From most people I'd say, "Them's fightin' words!" In your case, I'd say, "Them's divin' words!"

Also instead of "pistols at 10 paces", I guess it would be "doubles at 10 fin kicks". Either way it would still be at dawn with you.

Robert, as soon as I get over this cold, we've got to go diving!

que'st que c'est un "stroke?"

bon. un "stroke" c'est un plungeur qu'il les tres dangerous dans la vie et le apendages, tout que sont desiderable allez maintenez l'attache dans le corp

si vouz regard un "stroke" dans approchant, vouz pretendez ne'st ce pa les bonne tempes, et di "Mon Dieu, mon attack du cour c'est approxime, et je ne pul pas plungeur ajorduis."

quand le "stroke" van chercher dans outre "buddy," vouz donnez tout le gear, et rapidamont commence votre plunge.

Zut Alor, Andre de l'eau!

The DIR weapon of choice is the 18W HID underwater light saber. :D
 
As a couple of people have pointed out, the term "stroke" actually came from Parker Turner, who was one of George's cave diving instructors. And as several folks have mentioned, it is generally used to refer to divers with unsafe attitudes and/or diving practices. I don't know if the true origin of the word is (or ever will be) known, but it was often stated as part of the original "rules" of DIR diving:

Rule #1: Don't dive with strokes.
Rule #2: Don't listen to strokes.
Option #1: Don't dive. (sometimes stated as "Take up golf")

Another one of Parker's famous sayings was "Take the cotton out of your ears and put it in your mouth". If I'm not mistaken, this is supposedly the first thing that Parker said to George when he arrived in Tallahassee for his cave training.

Most of this stuff is probably still in the Cavers archives on Aquanaut, if any of you are curious to have a look.

Would you use the term for this divers gear set up , BTW the owner of that gear during that dive blew his NDL while trying to take a pic , wandered off 3 or 4 times, then on exit didnt listen and got knocked on his azz (tanks on coral ) and had to be saved. I had to go to him and help (risking myself agains a coral wall ) cause of his freaking camera. Havnt dove with him again.

What am I looking at? It that a yoke and a DIN first stage? I think the AIR2 or whatever that thing is on the inflator is a nice touch. It seems by looking at it that the guy is using a normal single tank setup with a pony bottle rig for doubles. Is my description accurate?

Which is really the only place anyone needs to look if they are wondering why DIR is controversial :)

BTW, I'm still trying to find Rule 6 somewhere ;) After all, it seems often referenced, yet poorly documented.

To add to Catherine's comment, in the motorcycle world, the equivalent term would be "Squids". History on it is somewhat uncertain, but apparently some of the 'old school' riders started to referring to the new sportbike riders as 'Stupid Kids' which eventually got shortened to Squids. Today denotes new riders purchasing brand new 1000 cc sportbikes and riding them with faux combat helmets, wifebeaters, short & sneakers :) As well, once they crash they skin / limb remnants are often squid tentacle like. So it fits on many levels.

I guess every sport has their thing. It is interesting though that in diving the term is used by one sub-group only.

I've got the same thing going on.
Have you gotten a new first stage yet? I can't dive with you until you have. Rule #6, you know!:D
