Just to add my two cents (I do cosmology research) to the chorus of complaints about this post, this research is NOT about discovering a new form of dark matter. This is about solving the "missing baryon" problem, which is a whole different kettle of fish. It's well known how many baryons (normal stuff) there should be according to big bang theory. However, if you look out at the universe and count observed gas and stars, you just don't see as much as you should. So people have assumed there are some hidden regions, where the gas is too cool to emit significant radiation for example, that contain enough baryons to make up the missing baryon budget.
Also, this seems pretty provisional stuff. I doubt this is the final word on the missing baryon problem. It certainly has nothing to say about the nature of dark matter or dark energy. But I guess some gushing "dark matter discovered" hype is just too tempting.
- There's not a single need for TeX left. It's obsolete, obviously and painfully so.
So you're saying there is a superior alternative for typesetting highly mathematical documents (bearing in mind that TeX is free)? What is that? (I'm sure there is one, you clearly have an answer to every possible question).
I live in a hole smeared with shit and dung, in the dark, in a moist cold basement on the outskirts of Boise, Illinois. This new Mac Mini is perfect for me!
In this image it looks like the planet has a bump on the lower left side. Could this be a mega-Olympus Mons (on a gas giant, hmm)? Yeah, yeah, I'm sure it's just noise, but it's fun to over-analyze images.
I hope they get this wrangling over the site over with soonish and get down to building something. We need some abundant energy source pretty soon to avoid either global anarchy when the fossil fuels run out or global catastrophe when we gas the planet with CO2. ITER is the best chance yet. I bet there'll be cool science/technology spin-offs too.
I've often felt that there is something in the makeup of the slavic brain which creates the potential for feats of mathematical and technical wizardry unavailable to the western mind. Several factors could be at work. Just as Murray Gell Mann taught himself particle physics from dusty old textbooks in second hand bookstores, perhaps the use of outdated educational materials in dilapidated classrooms fosters extreme tenacity and originality in predisposed minds. Or perhaps the lack of exposure to brain-toxic Western influences, the Britneys and the fast food, coupled with good wholesome fresh produce (including copious quantities of potatoes - boil em, mash em, stick em in a stew) leads to a growth spurt in the relevant areas of the cortex. I for one have welcomed, and continue to welcome, our Slavic overlords.
No dude, I have the Mac, just not a dipped one. Your failure to include this logical possibility in your analysis leads to me to conclude that you are a tard.
God, I just read that as the highest rated X[XX] gigs of unwatched [hardcore filthy animal porn] video. What is wrong with me? Arrghh

I couldn't use Expose as a replacement for virtual desktops. I tend to put separate projects on each different desktop, not windows of the same type. So for example I will have TeX files and a DVI viewer for a paper I am working on on desktop 1, C code and a plotting program on another, etc. etc. It would be much less efficient for me to collect all the files I need using Expose. I tend to use Expose as a cute way to switch between say 5 Safari windows. It would be hideous trying to organize 50 windows with it.

I haven't tried Desktop Manager, but I use CodeTek Virtual Desktop Pro on my Powerbook. I have to say, looking at the screenshots on the DM website, I don't particularly want to switch. The CodeTek pager is much much nicer, and I certainly don't want a big volume control style white icon in my face every time I switch a desktop. But maybe DM is a bit faster - CVD can take a second or two to switch desktops. I also need perfect integration with X11, which CodeTek has.
Obviously p has to be odd, so we can only add even numbers to it. Also we might as well specify that a,b,c,... are all different. So how about:
There are an infinite number of prime tuples, where a prime tuple is a set of prime integers of the form (p,p+a,p+b,p+c,...) where (a,b,c,...) is an increasing set of even integers less than or equal to p-1.
Oh dear. Maybe a prime tuple would be better defined as a set of prime integers (p,p+a,p+b,p+c,...) where (a,b,c,...) is a set of integers less than p of your choosing. Maybe this is still stupid.
There are an infinite number of prime n-pairs, where an n-pair is a pair of prime integers (p,p+n).
I also propose geordieboy's second conjecture:
There are an infinite number of prime tuples, where a prime tuple is a set of prime integers of the form (p+a,p+b,p+c,...) where (a,b,c,...) is a set of any integers of your choosing.
You can't use parallax to get the distance of a galaxy! It's way too far away. It's done by finding the redshift. Light waves from a distant galaxy are stretched as they travel, due to the expansion of the universe. The factor by which the wavelength increases (minus 1) is termed the redshift. The most distant galaxies known have redshifts 6-7. Cosmologists almost always use redshifts rather than times. The redshift is measured generally by looking at the spectral lines in the light from the galaxy, and comparing the wavelengths of those lines with those in a non-redshifted spectrum.

I think we can assume he was referring to the rest energy and rest mass, Einstein.

I think you're right about that. Very insightful, sorry I don't have mod points for you.

Will it buy me a G5? If so I'll throw in the frank as well as the beans.
You have very stringent anti-scratch requirements. I salute you.

Third time lucky.
Good question. See my comment above.
And the same goes for the definition of prime n-pairs too,
obviously.
Oh dear.

I propose the geordieboy conjecture:

an n-pair is a pair of prime integers (p,p+n).
