Cumulative General Science/Technology Quiz

[Catharsis]

Stop being such a baby. Ok in future I wont play sionara.

72 hours what fool came up with that?

I didn't read the rules anyway, and frankly if there that stupid then there's no point in me playing.

Honestly 72 hours? Anyway deleting my question so stickciv doesn't have a paddy on me.

They are quite clearly written in the OP. It's the same format the History Quiz uses, invented by Knight-Dragon, I think, and it works very well there. It's only fair that if you answer a question correctly, you should get to ask the next question, and as you say, not everyone runs on 'Yank Time', so we have to take timezones into account. Just be patient.

As for the light-bulb, was it Joseph Swan?

Well I didn't read the rules and they are stupid. So yes it's Swann but I would of also of taken A Scotsman who's name mysteriously eludes me now. Still since I am not allowed to play and that question is redundant I'm going to sulk in my room.


72 hours is a joke but no ones forcing me to play so there we go. Like he said if you can't play within the rules don't play. In that case no I can't because they suck. So I wont.

 

[Sidhe]

The OP came up with those rules, and frankly, they're a lot better than letting it be a free-for-all.

Maybe in the future, read the rules. It might just be the smart thing to do if you have no idea whats going on.

They suck. They suck. They are stupid and no one is suggesting a free for all, but on a forum with a high turn around 72 hours is preposterous quite frankly. Whenever I ran comps I just left it for 12 hours or less depending on the situation and then opened it up again. Keeps it moving, otherwise its just a snails crawl.

Like I said though, me not agreeing with the rules shouldn't stop anyone else from playing, but have fun with that and gl, I'll be elesewhere *takes football* and storms off the pitch

 

[Catharsis]

Uhh, alright then, Sidhe, always good to hear from you.

Let's just get on with a question.

In cosmology, what is Ω, and what effect will its value have on the fate of the universe?

don't worry I was only joking.

It was just his tone as if I'd stolen his lunch money and punched his gran.

I should know that? But I don't. I'll take a guess that it is the point at which the universe becomes too diffuse to support chemical/nuclear reactions.

Or to put it better the point of death, before the final heat death or maximal entropy?

 

[Genocidicbunny]

No, my tone was of annoyance at you being ignorant and egoistical about not reading the rules. I dont care if they suck in your opinion, they have worked fine so far.

As for what Omega is in cosmology, it refers to the density of the universe.

Egotistical, you mean saying the rules or should I say 1 of 10 are are garbage is egotistical, btw that's the only thing I was being serious about, because that is stupid, but hey it's not my gaff.

Yeah ok. pffft, stop whining at me, Christ I deleted the question didn't I? Is it your time of the month? is that what it is?

Anyway I looked it up on Google and that is essentially correct, you forgot to answer what it means to the eventual fate of the Universe though.

EDIT: Oh and retrospectively I really did know all that off the top of my noggin, I assumed you weren't allowed to use Google as that would be absurd; it's all basic physics, well the satellite thing isn't but it comes up all the time when people ask for proof of SR and GR so I must have said that crap about a hundred times on another forum by now. And that stuff about maths there is all out of an email I got recently from a friend + my own work to some small extent. The bulb thing is from another thread n another forum too, plus it comes up all the time.

Just in case anyone thinks I cheated.

 

[Perfection]

Is Ω a measure of topological flatness, with a value on one side of 1 indicating big crunch and the value on the other side indicating ug freeze?

 

[Catharsis]

Because I'm an uneducated peon, I don't know what 'topological flatness' or 'ug freeze' are, but Perfection's answer combined with stickciv's seems correct.

&#937; is the ratio of the total density of matter in the universe over the 'critical density' needed for a flat universe (which will decelerate but not recede). If &#937;<1, there is not enough matter in the universe for gravitation to overcome the expansion, so there will be an 'open universe' which will keep expanding forever. If &#937;>1, there is enough matter to cause the universe to stop expanding and then recede, causing the 'Big Crunch'. This is a 'closed universe'. And if &#937;=1, that's a flat universe.

Perf and stickciv can now fight to the death for the right to post the next question.

 

[Perfection]

I'll give it to stickybuns, he earned it beforehand, and it was cruelly denied to him.

Hey don't cast me as the bad guy he was right just not perfectly right.

Let him go, seems like an equitable conclusion?

Topology is just a fancy word for shape in this case, or the sacred geometry of space time, ug freeze God knows.

 

[peter grimes]

Glad I missed most of this vitriol.

But I'd say that if Sidhe has such a problem with the stated 72 hour rule, he should start his own Quiz thread with rules that he likes

And I don't think anyone made an accusation of cheating. Did I miss something?

[/OT]

It's interesting that Omega is the symbol that was chosen to represent a variable that determines the end of our Universe

I see irony is wasted on you. But no that's not what I was trying to say and nm.

Well I didn't read the rules, I just assumed them, so to make sure I know the basics of this guff, being as I have a few posts on this forum, and because these days everything I say is over analysed to the point of trolling, I clarified.

 

[Genocidicbunny]

Alright, since I was reading about these not long ago:

What is a HEAT round and how does it work? (Oughta be easy enough)

 

[ainwood]

It stands for High Explosive Anti Tank.

I believe that when it hits its target, its explosion is hot enough to liquify metal, that is then propelled through the armour of what it hits.

 

[a_propagandist]

High Explosive Anti-Tank round. With a shaped charge, the round creates a blast that penetrates the armo(u)r by directing the explosion towards the armo(u)r.

Edit: xpost. I'll leave it up anyways.

You're both correct on the name, but not on how it works. Not quite right at least.

 

[brennan]

Aren't they the missiles that use a high explosive warhead to drive a high density (DU) penetrator through armour?

 

[peter grimes]

I thought that HEAT rounds have a rod of solid copper running down the axis, and when the round contacts the target, the temperature is high enough that the copper liquifies and bores through the armor plating. This is in contrast to a depleted uranium round, which remains solid.

But I may be way off - this really isn't my cup of tea, for I'm really a pacifist at heart; I loathe the enormous amounts of effort humans invest in killing eachother

 

[Genocidicbunny]

I think you're the closes we're gonna get.

What happens is the explosive charge detonates a few inches away from the armor and compresses a metal liner into a solid jet of metal. This jet, traveling at around Mach 25 then punches through armor.

You're up brennan
