Well considering they were talking weeks to start the 2nd beam....yet got it going yesterday too.....they may be coliding sooner than that.

The one thing that's bugging me is this.......

Relativity tells us that with two beams travelling at C (OK 99.9999999999999999% of C, but for now, we'll CALL it C), their closing speed as observed from one particle in the beam with still be C because that particle will be experiencing time dilation. But, If I, as a stationary observor, see one beam at C, and another beam at C, and my relative velocity to both remains constant.....surely I am observing a closing speed of 2C.....which is of course, impossible.

("I" in this case being my instruments, as I doubt you'd have much luck spotting a single proton doing 186,000 miles per second.)

So if Anyone is qualified in teaching grannies to suck eggs, or smart arse paddies to talk shite, as the case may be....please post explaining how relativistic concepts are preserved in this scenario.

you f_____ WHAT?

Cambo, physics says as things speed up closer to C, they actually don't double in speed... use Einstien's equation:

u= (v+w)/[1+(vw/c^2)]

Where u=the noted velocity of both objects by the stationary object v=the speed of one object w=the speed of the other object

(of course everything is done in m/s)

So by this equation, nothing exceeds the speed of light, even if opposing velocities added together... does that help?

'To see a pool of water in your dream, indicates that you need to understand and deal with your emotions. You need to dive right in. Alternatively, a pool may indicate your need for cleansing. You need to wash away the past.

In particular, to dream that you rescue someone from drowning, indicates that you have successfully acknowledged certain emotions and characteristics that is symbolized by the drowning victim.

To see a naked person in your dream and you are disgusted by it, signifies some anxiety about discovering the naked truth about that person or situation. It may also foretell of an illicit love affairs, loss of prestige and scandalous activities. On the other hand, if you do not have any problem with another's nudity, then it implies that you see through people and accept them for who and what they are.

To see a robot in your dream, indicates that you are going about life in a mechanical and rigid way. You have lost the ability to express your feelings. Alternatively, a robot may symbolize the way you view your working life.'

So to summarize you're a DIRTY DIRTY man who needs a wash, who either has illicit love affairs and scandal in mind or happily accepts that your a dirty dirty man and that you are far too rigid so may benefit some WD40

I dreamed I was in a science lab being besieged by zombies and caving their heads in with a huge axe. only now do I see the source of the (mutual) anxieties in those two dreams...

To dream that you are in a laboratory, signifies that you are experimenting with your inner feelings, beliefs, and fears and testing yourself. Alternatively, you may be going through some sort of transformation.

To see or dream that you are a zombie, suggests that you are physically and/or emotionally detached from people and situations that are currently surrounding you. You are feeling out of touch. Alternatively, it may indicate that you are feeling dead inside and are simply going through the motions of daily living

To see an axe in your dream, indicates that you are overly controlling. It is symbolic of destruction, hostility, and the frustrations that you are experiencing. Perhaps you "have an axe to grind" with someone

To see violence in your dream, indicates unexpressed anger or rage. You need more discipline in your life.

So to summarize you're dead inside and need to transform but your controlling nature and the opinion of others frustrates you and you won't allow your self to,

Be more disciplined in your quest for the real you... Sod everyone else and slip into that nice cocktail dress and a pair of killer heels

He does that every weekend but!

Erm, I seem to have disappeared into a parallel universe where England beat Croatia 4-1 away from home and were actually quite good.

Ahh yes, down with science, learning is the devil's work!

Here Edel.....that equation only covers one proton beam as view from either a stationary observor or from the other beam, it does not cover a statioary observor watching both beams.

I think you missed that 'u' is the velocity of both beams hitting each other... or also as the velocity the stationary object would see. So the equation is talking about all three 'velocities' that you are questioning.

I can't really explain how the equation is fully correct, I'm no astro-physist, I can only relay what the equation means as in the way I learned it

Well, if you put values into it, it comes up with silly numbers.

If we assume the particles are AT C, instad of 0.99999999999999999999999C...........

U=(C+C)/(1+C)/C^{2 so (with the 1 rounded out as a differnece of 1 in 300,000,000 (taking C as 3x10}9) is negligible for a broad answer) u=(2C)/C/C^{2 Therefor U=2/C}2 =barely moving.

One of us has done summat daft here.

yeah, you daft cnut! You gotta do yer math right first!

its:

u=(C+C)/[1+(C*C/C^2)]

u= 2C / [1+(C^2/C2)]

u= 2C / (1+1)

u= 2C / 2

u= C

Must have copied the homework question down off the board wrongly sir.

You completely missed the brackets....

.... but I kinda had the paranthesis wrong... edited my other post right after putting up the last post :D

i,m here but only just!

Had the tom tits on wednesday,must av been summat to do wi that particle collider jobby

I had the shits last night.

I blamed it on the Spanish restaurant where I had dinner, but it seems I may have caught it from this place.

It's strange, that ever since its switch on, I haven't been able to log into this site properly, weird.....maybe, I am in some parallel dimension

Perhaps, after all your recent dating problems, you've gone and ended up being trapped inside a black hole.

uh-oh!

Exxxceelllent.

my eyes actually widened for a moment and my mouth went into an 'o'. i'm so gullible it's ridiculous.
