FTL communication ftw!
I'm going to do something new here in the political forum. I'll attempt to post one "cool" scientific discovery a week. Feedback appreciated. Perhaps in the future, some work with the potential to impact current political or economic policy will be in order.
This weeks edition involves quantum entanglement or spukhafte fernwirkung as Einstein once mused.
http://www.scientificamerican.com/ar...e-entanglement
Usually a finicky phenomenon limited to tiny, ultracold objects, entanglement has now been achieved for macroscopic diamonds at room temperatureHypothetically speaking, a technology like this could be used to identify "changes" in the state of one object many miles distant through state changes in an object in close proximity (think security). That would, of course, require many refinements to current technology and the ability to reproduce results in an uncontrolled environment.A group of researchers report in the December 2 issue of Science that they managed to entangle the quantum states of two diamonds separated by 15 centimeters. Quantum entanglement is a phenomenon by which two or more objects share an unseen link bridging the space between them—a hypothetical pair of entangled dice, for instance, would always land on matching numbers, even if they were rolled in different places simultaneously.
FTL communication ftw!

Great idea. Even if I don't post in it every week I will definitely be reading.
ok
Thats freaking cool.
Nah, we still supposedly can't communicate info ftl... I always thought that no communication theorem was a total copout
Edit: Also, from my laymans perspective, the "dice" analogy seemed poor, as the entangled pair shows the opposite spin/axis of the one measured. A coin flip would have been better, where if one entangled particle showed heads the other would "spookily" flip to tails.
Still though, it's awesome that the size limits of entanglement keep increasing. Those diamonds are pretty large. Couple that with the delayed quantum eraser (and in the words of zoidberg, some quantum tunneling why not) and you have some freaky possibilities
totally beyond me. sounds neat tho.
Quantum mechanics are the most non-intuitive thing I've ever read about in my life, but that's what makes it fun to learn about.
Was this after they found a cure for cancer?
"And therefore as a stranger give it welcome.
There are more things in heaven and earth, Horatio,
Than are dreamt of in your philosophy."
Even forgetting about biological evolution and anti-evolution assholes like mouse, quantum, sub-atomic physics is one of those areas that exposes "Christian" Bible-thumpers so ridiculously, evilly wrong, a entire class of simplistic, childish jerks consecrating themselves to believing and propagating lies "in the name of Christ".
Quantum mechanics is child's play compared to the incredible complexity of the biology of cancer. GFY
Cool.
Interesting implications for the end of the universe.
Billions of years from now, after entropy and expansion have sucked all the heat out of the universe, I wonder what this would mean for the last, far far isolated chunks of cold matter.
Ever read any Stephen Baxter? He likes to play with the entropy scenario.
Good grief. Shut. The. . Up.
boutons-stalker TB always bringing high quality content.
I'm not sure you're qualified to make this statement......after all, you did win Worst/most embarassing liberal poster in 95% of other users opinions.
lol @ stalker.
You're a walking non sequitur. Get over yourself.
Hmmm, never really read any of his stuff, but will stop by the local 1/2 price tonight.
Thanks!
My general sci-fi reading is more military-ish in nature. Hammers Slammers, Honor Harrington, etc, but occasionally I venture out of my comfort zone, and the wiki description seems intriguing.
I will give it a try.

I thought it was strange enough that motion stretches time and space and that you still get an interference pattern on a screen shooting one photon at a time through the double-slit, but quantum entanglement just takes the weirdness to a whole new level.
Page one has yet to get going and this vato is already verbally insulting people? hence why he didn't make the top 10 list.
When has anyone in this topic brought up the bible, Christ, or religion?
Agloco, I am posting this in the spirit of this thread and hope not to hijack it. If i am stepping on toes then by all means tell me to off. I just thought that this was truly groundbreaking as it allows us to model the mechanics of biology in the nucleus. With all that is being done with gene therapy now, this has obvious application implications.
If you can model gene expression then you can find ways to manipulate the model. Chemicals that straighten out DNA and nanotechnology delivery systems already exist. Thats just off the top of my head.

The mapping technique that Aiden and his colleagues have come up with bridges a crucial gap in knowledge—between what goes on at the smallest levels of genetics (the double helix of DNA and the base pairs) and the largest levels (the way DNA is gathered up into the 23 chromosomes that contain much of the human genome). The intermediate level, on the order of thousands or millions of base pairs, has remained murky.
As the genome is so closely wound, base pairs in one end can be close to others at another end in ways that are not obvious merely by knowing the sequence of base pairs. Borrowing from work that was started in the 1990s, Aiden and others have been able to figure out which base pairs have wound up next to one another. From there, they can begin to reconstruct the genome—in three dimensions.Brave New World.Through their research over the past few years, Aiden and his colleagues have discovered that at the level of a megabase—1 million base pairs—the human genome has wrapped itself into a structure known as a fractal globule. Although the spherical globule might look like a mess, the researcher discovered that by analyzing proximity data it is in fact an elegantly organized structure, which can be unfurled without getting tangled.
"Though it may sound abstract," Aiden wrote in his new Science essay, "the fractal globule is easy to explain to graduate students because it closely resembles the only food we can afford: Ramen." Uncooked, 30 meters of noodles fit neatly into a small package, woven together without being tangled.
I nominate the discovery of Kepler 22b for next weeks discovery of the week.
