Ask a physicist anything. (5)

Is it possible that the upper U.S. is going to super freeze within the next two weeks?

I've heard that it has been called the "Iceman cometh" or something super weird like this.

I just reinstalled Windows XP on my computer so I can't find the link again.

Apparently, there are some scientists who believe that cities like Chicago won't even get a high temperature for the day above 0 degrees Farenheit later this month.

I'm not so sure if I'm quite ready for such a blowfest like this.

Global warming does predict such adverse weather patterns. It matters not whether it is man induced or a natural cycle; Whichever may be the cause, one thing is for certain; Mankind is in for a very rough ride this century!

Well, thank God I'm not a real man!

No. Usually I qualify things with 'probably', but... no There may be some cold weather, and the UK is still in the grip of a nasty cold snap... but nothing on par with The Day After Tomorrow!

 

[Steffenfield]

I would never compare this world to a cheesy movie.

But yeah, I think in ten days from now, I'll be a little bit super chilly.

Have you heard about this upcoming front that will hit the upper U.S.?

It hasn't been on any of the local news just yet.

She'll be coming round the Arctic when she comes!

Explain how you reprocess spent nuclear fuel and if it possible to stretch 70 years of fuel into 3000 years?

You buy out the media and lie lie lie!

Deny, deny, deny! Then lie, lie, lie. Because as Goebels used to say: "The bigger the lie the more it will be believed".

What are wormholes?

 

[Nostromo]

they're like foxholes but with less room.

 

[Wiccan_Child]

What are wormholes?

They're what happens when a physical system (e.g., a ball of matter) undergoes some event (e.g., being crushed) that makes one of its properties (e.g., density) sky-rocket to infinity.

The result is a singularity. When matter collapses in on itself, and the gravity causes it to collapse further, the density goes up and up - the result is a singularity, because one of its properties is basically infinite, and this particular singularity is called a black hole.

A wormhole is where two black holes 'join'. This happens because black holes warp space around them, and can occasionally join two distant points in space together, like so:

The flat bit is space, and the tunnel is where the two black holes have created funnels in space, which meet, creating a tunnel.

Wormhole!

So you won't tell me how they reprocess nuclear fuel

How do they join when up since I thought spacetime is flat?

 

[Wiccan_Child]

Hey, I already told the Chinese!

Spacetime is like a big block of rubber, all wibbley. Black holes warp space, pulling it towards itself. So black holes pull other black holes - and other wibbles in space. When those wibbles intersect, they merge like two bubbles colliding.

Wormhole!

Ok thanks. Hopefully my GR module will explain blackholes in more detail.


Now how do you get 4 figures in a 2 by 2 format in latex?

 

[Wiccan_Child]

There's only so much I can do with pure text without bogging it down

Well I wasn't expecting you to write a paper on the subject But I get about 15 hours next term to lean about GR and hopefully black holes will be covered.

Doesn't matter, I used the epicness of paint to merge all my images into one and now latex is playing nicely.

Ah the joys of writing a report for monday

Who knew that when you force yourself to stay up to do work, forums become really really appealing

LaTeX is a pain in the behind - so I got someone else to do my papers in my first year of uni

First year was Microsoft Office all the way but when your supervisor tells you that he prefers latex, I got to impress.

Mine was an old Russian professor whose grasp of English... wasn't so good, to the extent that we had no idea what equations he was using. So I went away, derived the same result, and so we had a clear idea what all the terms meant.

I don't know if he was just mental, or if it's standard in Russian, but I couldn't for the life of me figure out what was going on

What is your favourite element (from the periodic table, of course), and why?

I'm also interested in superheavy elements. Please could you explain them to me?
