Good luck, that's a patented Skinner family recipe not available to the public.

You can have a peek at the localized aurora in the kitchen, though.

Wow, cromulent is also in the dictionary.

cromulent
adjective

Appearing legitimate but actually being spurious : These citations are indeed cromulent

Excuse me while I look up some recipes for steamed hams.

Kakslauttanen Arctic Resort in Wintertime

moonsammy says...

This looks amazing. Seeing the aurora is something I've wanted to do for a while now. Crossed eclipse off the list this year at least!

For those of you who haven't seen the Aurora (borealis, in my case) light, just go fix that immediately, its a sight to behold. Sure you can find videos of it on youtube, but so can you of a beautiful sunrise or sunset. Seeing it in real life... it really is something else entirely. I was once stuck in a tent on top of a mountain in northern Norway (in Troms) and went out for a wee, and then.. then i looked up.. the ENTIRE night sky (like edge to edge vision and horizon(s) ) was moving and dancing in spectacular green, purple and every other color I could imagine, it was a sight to remember, I tell you.

Those Aurora model sets shown here....Remember these from the 70's, always thought they were funky-cool. Went to Ebay expecting to find very few and found over a thousand listings-Model kits were big-time disposable-kidincome toys when I was younger-

Clicked one (prehistoric cave bear), two monkeys had placed bids of over $25US....for an empty box!!

EEEEE EEE EEEEK!

Thanks for not talking during the feature

Piers Morgan - Alex Jones Goes 'Full Retard' Part 1

KnivesOut says...

Why is anyone listening to Alex Jones talk about anything, let alone put him on CNN?

This guy seriously believes that all the recent rampages are somehow staged "False Flag" attacks perpetrated by the Anti-Gun Establishment. Aurora, Gabby Giffords, Newtown. He'd have you believe that the government is programming disaffected teens to trigger into psychotic murderers like the Manchurian Candidate.

Seriously, what the fuck? Put him back on the street-corner with his card-board box and "The End is Nigh" sandwich board.

More Faux Rage from Ann Coulter

Yogi says...

Don't call me son, faggot. I'm talking about tragedies like Sandy Hook and Aurora. Not assault rifles means a lot less people getting killed. Statistics only makes sense in a context, and our assault weapons ban was useless because it wasn't enforced at all. What I call owning a death machine you call Liberty, good for you.

You're a liberal in the sense that Obama is a liberal.

You need to fix your goalposts son. To start off, the burden of proof is on those that seek to prohibit something. You could never show, for instance, that anything "won't help" anything else. That's asking for proof of a negative. It belies your profound misunderstanding of statistics. We had a nationwide assault weapons ban. It's efficacy was unimpressive. It certainly did not provide any conclusive evidence that the ban was effective which is where the burden should lie for restrictions on liberty.

There are also these things called "priors." For example: "An extremely small proportion of homicides are conducted using assault weapons. Thus, the maximal impact of their ban would similarly be small." If you want to ban anything it should be handguns, but I don't view that as consistent with the second amendment at all. You would (or at least should) need a constitutional amendment to pull that off.

Finally, I view homicide in general as a relatively small problem in comparison to other matters of public health and safety. That is if I look at numbers, as opposed to guessing at probabilities while I'm crying a river over news broadcasts designed to make me feel unsafe.

Sometimes being educated means considering other points of view. I'm a liberal and I don't own (or wish to own, or even really enjoy) guns. You have a fucking gun in your avatar.

Large Filament Eruption On The Sun: 8/31/2012--SPECTACULAR!

kceaton1 says...

*promote

This is most likely the most AMAZING filament eruption to be caught on video. It is caused by a little process called magnetic reconnection. It's a little process that gives us our solar flares, these filaments, CMEs (Coronal Mass Ejections), auroras, and the possible potential for very dangerous radiation storms every few millennium--give or take a few. Basically, plasma flows along these field lines of magnetism. When things get out of hand, then those field lines distort and change and all of a sudden things get very dangerous (AND sometimes beautiful). The faster the magnetic field changes the faster the particles will travel making them more and more dangerous as the events unfold fast enough giving them more energy (kinetic & heat), which in turn if directed at us means it penetrates much further into our protective field and anything outside of the field, crispy--in the shredded DNA, cells, you name it sense.

Occasionally, Earth's magnetic field breaks down a bit (if I remember why correctly it was a certain "sequence" within our magnetic shield and it reacts badly with the Sun's--don't quote me though, I really need to look it back up again it was a very long time ago I remember this from), if a large solar flare directed towards Earth ever happened before Earth had enough time to fully build back it's strength we would be FAR more in trouble than usual, but this would be a rare event. Usually what happens is that the charged particles follow Earth's magnetic lines and go to the poles, which is the one place on Earth where you do suffer the most radiation from the Sun (basically wherever the poles are as the plasma follows the polarity or "field lines" of Earth's magnetic field). It's also why the closer you are to the poles the better your view is of the aurora as the particles streaming in, if there is a sufficient quantity moving very fast (the more energy, especially kinetic--speed, the farther the penetration into the atmosphere and the lower the aurora becomes visible), will enter the atmosphere and begin to be absorbed by various elements that our atmosphere is compromised of like Nitrogen.

Here's a quick explanation. Basically, the particles collide with atoms of molecules/elements or anything in the higher atmosphere, exciting their electrons into higher energy levels, which is known fundamentally in science as quantum leap/atomic transition/electron transition it's one of the atom's most fundamental abilities dealing with "extra energy" being pushed into a system that wants balance (this is a very common process that happens ALL DAY long, EVERYWHERE around you; it transfers photons essentially--pure energy--BUT, what is the energy in the form of as it's energy level makes it do very many different things; you could see things, what you consider the normal range of light--it's EXACTLY how light goes THROUGH a window--it doesn't go through the window it is transferred via the atoms from one side to the next, this is ALSO why people are trying to get invisibility to work as it just might; HEAT is another one that is transferred all the time--it literally radiates outwards from our bodies and then we are surrounded by excited electrons and the infrared range of light we are putting out, the heat of a human body...or any animal; this goes on and on, it happens everywhere and as I said ALL-THE-TIME, it's perhaps one of the most critical processes and abilities of the atom and how photons also transfer their energy between areas in a direction; a little off-topic information for those that don't realize how much is going on, everywhere, all the time, at any given second...it's a complicated, but beautiful world)), and making them give off light that we see when the charge they've taken on finally returns the molecule/element's electrons to their normal orbits in the electron shell; the color depends on what molecule/element was being bombarded and how much energy was involved from the particle that hit it). This of course transfers all the energy that those particles had and we get a nice light show.

/I thought I'd fill my promote with something useful; ...on why these happen...
//edit-For a little more clarity, grammar and a bit more information that I hope some will appreciate if it helps anyone learn something or atleast go look up some of this and learn some on their own; taking an interest in science, it's one of the most important things in the world that we have.
///Spreading science is just as important; it's the one literal thing we do/use that has ever allowed us to deal with the worst problems we have: fear, pain, death, disease, sorrow, despair, ignorance, etc... Science IS the light in the dark. It is our best hope for mankind's continued existence and a good life. It is the single most important activity we now do as a group; it's our savior from us and what's out there...

Police officer deals with open carry activist

MarineGunrock says...

Fuck, that mentality scares me.

As a former combat arms Marine, I've had countless hours behind the butt of an assault rifle and I still don't think I could have really done shit in a situation like Aurora. If I had a clear shot, sure, that's easy enough as long as I'm not shot first. But when you have people running around and screaming (not to mention the fucking smoke screen) I'd be very hesitant about returning fire.

Compare that to some 22 year old thinking he's Billy Badass who took a 4-hour concealed carry permit class. Suddenly he's fucking Rambo and thinks he can save the world. Never once do these idiots think about ANY of the details.

Couple of Ayn Rand loving freedom fighters. If we only these guys were at that Batman screening I'm sure they would have handled the situation well.
