Is this actually the CTYI??

As in Center for Talented Youth in Ireland, or am I completlely wrong??

Didn't the sickened sense of humour give it away?

I don't know of any lecturers here, but to my knowledge anyone's welcome. If I'm right, we had some non-CTYIers for a while. Until they got bored (or sickened) into leaving!

LegacyUser

ooh we're free for all eh?
then who let fiona gillan in here?!

ahem.
who are you nesf?

a lecturer, but I'm also a student at UCC..

I'm a lecturer too!!

I've just done my third lecture on making the internet go faster!! Seriously!

And the principle/form master didn't show up this time either. It went great.

Do you care?

Didn't think so

Step 1: Move to a country with a decent asdl/etc network.

Step 2: We'll leave this for homework kids

Physics myself

No, it involved making light go faster than c and replacing all of the Fiber Optics and routers in the world, but its still actually possible and feesible!

}:>

BTW, what's a nesf?

LegacyUser

Physics? I have a very strange physics teacher. He showed us a programme he had recorded off National Geographic about crop circles. One guys theory went something like this "I saw these trees and there shadows were overlapping and then it dawned on me! They were making a 60 degree angle - hence crop circles are actually places where the space time continuum has torn and had to be fixed! Crop circles are necessary to patch up the space time continuum!" Odd fellow I'd say.

But, yes! I just discovered that I have no more school until September! Aren't I great?

And I have the best solution for making light travel faster... it involves manipulating time and it's mine! MINE! BWAHAHAHA!

LegacyUser

Um, actually the light travelling faster is what manipulates the time. Soz.

LegacyUser

I know that...but I was tired and bored and wanted to say something and ...
"Arr! I don't know what I'm doin'"

what are you lecturing in at ctyi dis summer?
will you bring balloons and jelly tots into class?

First the light doesn't travel faster than c, its a relativistic effect combined with measuring the phase angle etc

a nesf, is short for nesferatu, which is a misspelling of nosferatu, which was an attempted joke of a mate of mine on a website.

Long story

LegacyUser

Actually the light pulse was accelerated to 107% of c. See nature.com

}:>

LegacyUser

Relativistically.

Light cannot travel faster than c, it only appears to do so. e.g. you can "slow" light by passing it through a caesiam gas field, but from the perspective of the light it is travelling at c.

Depends totally on what your interested in though. e.e. you want your information to travel faster than light, this can be done, I'm only interested in the physics of the problem. In other words, we;re both correct from our individual perspectives

LegacyUser

c is simply the definite speed of light in a vacuum. In a vacuum, no light can be accelerated or slowed beyond c. However, in the real world, it can be slowed by obstructions (e.g. almost anything, but sodium's particularly good), or refracted by things like caesium thereby accelerating it beyond c. In general, light usually travels at about 99.99999% of c.

}:>

LegacyUser

I must disagree, c is the true speed of light in all inertial frames of reference (i.e. a frame where no acceleration is present).

I've no good HTML links, but take my word for it, the speed of light is constant. It's merely a trick to make it appear different. e.g. in refraction, a basic definition is that the co.eff. is the ration of the speed of light in the 2 medias, but in reality, it is constant in both seperate frames of reference, i.e. from the perspective of the glass, for example, the light is moving at c within it and faster than c outside it.

I think where you're making your misinterpretation is in that you are choosing a preferred frame of reference, i.e. where you are standing, but this only leads to error. It is a basic postulate of the relativity principle that there is no preferred frame of reference.


Then again this is pure semantics.

LegacyUser

You all sicken me.

Up apathy!

On that note, I think Nesf and Deirdre are right! As far as my memory serves me, light always travels at a constant and it's just your perception that changes.

Or something. I really haven't looked up much on light.

LegacyUser

just thought i should contribute-i haven't been paying much attenttion lately. and by the way my sister is lovely.

LegacyUser

btw do u all no who i am now? ah **** hate that

LegacyUser

In the Theories of Relativity (and before that), c was defined by Albert Einstein as the constant, unchangeable speed of light while travelling in a vacuum. I've done a project on the Theories of Relativity and one which focuses partially on the acceleration experiment. I obtained an original scanned copy of the theories and Einstein's speech and notes concerning them (in German), and also an English translation. And it does seem to be on my side.

}:>

LegacyUser

now listen...
if 1 has a laser gun that shoots light faster than the speed of c
the light will travel back in time and so you will see the effects before you shoot
so if you are about to kill someone and you see them dying b4 you shoot and decide not to shoot, what happens?
remember they are already feeling the effects


BARF

LegacyUser

That is what is called causality. Fortunately its only regular light pulses and beams that they've done this to and also the results aren't enough that it cold be visibly seen that the light had finished before starting.

On the other hand I'm studying physics in college, I take relativity as a subject, therefore I believe I can claim to have a better understanding of relativity, but I won't assume it correct as relativity can be very non-sensical at times

All I say to you is that you are thinking along the wrong lines, there is no preferred frame of reference.

See above posts ;D

Mwahahahhaha etc et al.

hmmmmm you all seem to know a lot about icky things like light and how it moves-does anything feel like impersonating me on the 18th of june when im meant to be doing my physics exam???no-one would notice, im sure we'd get away with it.

LegacyUser

Just go to http://www.nature.com/ and look through the bucketloads of articles they have on the experiments to slow and accelerate light. I think you'll see that I am in fact, correct.

I do realise that as a physics student you should have a very good understanding of relativity, but you do seem to be wrong so chekc out Nature.

Yet again Ian is wrong. Yet again he refuses to accept it.

IT'S NOT CUTE ANYMORE!

Nesf, you have my deserved respect. Or you would if either of us existed (don't ask).

Firstly LOL Again depends on your frame of reference, secondly Ian, take my word on it, physics article like that are not truly scientific, for example, i saw the cosmic string theory in a newspaper 5 years after it had been disproved!!!

A change of topic might be a good idea. Keep up the interest in physics though, its an excellent hobby/profession. But I feel I'm just a little biased in saying that

so the simpsons,anywho!!

LegacyUser

Well, the paper-report type thing I did was examined by two pretty good physicists, neither of whom saw any problem with the whole "light acceleration" thing. And they're pretty smart. So they are.

Maybe we'll continue this "discussion" at CTYI.

Am, I'm kinda making the same point over and over. I did not say what you said did not happen.

Just forget about, and read up on it yourself and see if you agree with me after some research on the topic in question.

PS I also ran it past a few lecturers at UCC, they agreed with me, but agree with me on that maybe you misunderstand what I am trying to say.

LegacyUser

OK, what you said was that nothing can ever exceed the speed of c. EVER. But it can, as my extensive research led me to find out. So nih.

I am a Knight of the order of knights who say nih!

nih nih nih nih etc

Seriously thist thread would have been locked 10 times over on the main boards by now


Well my extensive research indicates that asking to continue an argument in real life with a rugby player is usually not a very good idea!

(I'm kiddin' for those not used to my humour)

a=b*c/d => I am correct

LegacyUser

Can I have money now?

Good call Eilis.

Um... Ian, I think Nesf means that light doesn't exceed c. Full stop. HOWEVER, certain elements can make an object percieve light to be faster than c. For information, light must be percieved, hence by seeming to go faster than c light functions as if it goes faster than c. It sounds really good in my head, but I'm having trouble putting it into words... I don't quite mean what I just said but you can get the general idea of what I DO mean.

Curious, but who thinks that "All Squirells Must Die"?

After all, you did start this asking whether it was a CTYI board! You should know from experience that anything CTYI will automatically deviate from the point!

Except... Anyone remember the Cats Vs. Dogs thing? We need another good vs. thing...

LegacyUser

well,technically,this is a "nesf vs. imp" topic

but its soooooooooooooooo boring ,people!!
jebus!!

LegacyUser

"Jebus... Jebus help me...
I'm alone in this world...
And a F**ked up world it is too!"

Wake Up Dead Man.

Ok, my advise: Everyone avoid this board (including Nesf) EXCEPT Ian. That way Ian gets to feel like he's won the argument and everyone else gets to ignore him! Happy times ensue and the world dies of pollen. The end.

LegacyUser

lol

I can't be doing that now... I'm a stubborn *******

Plus after last sunday's hurling match Cork pride must be upheld whatever the cost!!

Personally, I'd lock this thread..... save us all alot of sleep
