So when can I get a quantum processor from Intel/AMD running with holographic solid state memory with instant data access (read and write) using spooky particles, and a total 3d holographic and tactile monitor?
And if these first prototypes get off the ground... can Intel still say their ghz procs are faster than these mhz procs?
How many cats will be sacrificed to test a 1024x1024 quantum array I wonder?

Well, so does my old 286!
I admit to knowing next to nothing about quantum computers or quantum computing. Well, actually I guess it is nothing.
However something seems wrong about using the term "megahertz" in regards to a quantum computer. I didn't think quantum computing had anything in common with a typical synchronous design. Can anyone clarify this for me?
MADISON, Wis. -- Researchers at the University of Wisconsin in Madison claim to have created the world's first successful simulation of a quantum-computer architecture that uses existing silicon fabrication techniques. By harnessing both vertical and horizontal tunneling through dual top and bottom gates, the architecture lays out interacting, 50-nanometer-square, single-electron quantum dots across a chip.
"Our precise modeling elucidates the specific requirements for scalable quantum computing -- for the first time we have translated the requirements for fault-tolerant quantum computing into the specific requirements for gate voltage control electronics in quantum dots," said professor Mark Eriksson of the university's Department of Physics.
The group of researchers has concluded that existing silicon fabrication equipment can be used to create quantum computers, albeit at only megahertz speeds today due to the stringent requirements of its pulse generators. To achieve gigahertz operation, the group has pinpointed the device features that need to be enhanced to prevent leakage errors, and has already begun work on fabricating a prototype.
"We believe that quantum computers are possible today with the component technologies we already have in place for silicon," Eriksson said. The team composed their quantum "bits" out of electron spin: up for "1," down for "0." Encoding bits in spins allows a single electron to represent either binary value, and because of the indeterminacy of quantum spins, they can represent both values during calculations to effectively create a parallel process.
"Our technique may enable quantum computers to actually begin performing calculations that can't be performed any other way," Eriksson said. Others have demonstrated a few quantum dots interacting to perform calculations but Eriksson estimates that a million quantum bits (qubits) will be needed to create quantum computers that perform useful real-world applications. For that, silicon fabrication equipment offers the best solution, according to Eriksson.
Eriksson's team matched silicon germanium fabrication capabilities to quantum-dot requirements. The result is an array of quantum dots, each of which houses a single electron, with electrostatic gates controlling qubit interactions. The team then optimized and exhaustively simulated the model, which it declared to be a successful design.
The design constraints included reducing the population of electrons in quantum dots to one, while permitting tunable coupling between neighboring dots. The team met those conditions by employing both vertical and horizontal tunneling to first confine and then slightly alter the location of individual electrons.
A back gate serving as the chip substrate acts as an electron reservoir from which quantum dots can draw their single electrons using vertical tunneling into the quantum-well layer. That layer acts as the vertical confinement barrier, with an insulator above and below it, enabling the vertical size of the quantum dots to be just big enough for one. A grid of top gates then provides the horizontal separation between dots by supplying electrostatic repulsion from above.
The semiconductor layers were formed from strain-relaxed SiGe, except for the quantum-well layer, which was pure, strained silicon. The bottom gate was formed from a thick n-doped layer with a 10-nm, undoped tunneling barrier separating it from the 6-nm-thick quantum-well layer. Another 20-nm-thick tunnel barrier above the quantum-well layer separated it from the metallic top gates, the team reported.
Researchers load the electrons into the quantum dots from below by adjusting the potentials on the top gates to induce an electron from the bottom gate to tunnel vertically up into the quantum-well layer. Once loaded, the electron stays in place because of the electrostatic force from the top gates. When the team weakens the force between selected quantum dots by adjusting the top gates between them, the adjacent dots are permitted to interact, thus enabling calculations to be made.
The normal errors encountered during quantum calculations could mostly be corrected, according to Eriksson's simulations. Careful consideration of the simulations led the researchers to predict that leakage could be tuned out sufficiently by low temperatures combined with a modified heterostructure that allowed larger electrical fields.
With existing fabrication techniques, the team estimates that a million-quantum-dot computer (1,024 x 1,024 array) could be built today and operated in the megahertz range.
Imagine a beowulf cluster of these :)

Is there a dilbert-esque techspeak generator they used for this article or what? The previous paragraph makes my head hurt...
One of the prime motivations behind implementing quantum computers is Shor's algorithm, which factors big numbers into primes quickly.

Factoring primes is primarily important for circumventing encryption (a "content protection" system).
So, would possession of a quantum computer violate the DMCA?
DIDDLING
Edgar Allan Poe, 1850
Hey, diddle diddle
The cat and the fiddle
SINCE the world began there have been two Jeremys. The one wrote a Jeremiad about usury, and was called Jeremy Bentham. He has been much admired by Mr. John Neal, and was a great man in a small way. The other gave name to the most important of the Exact Sciences, and was a great man in a great way- I may say, indeed, in the very greatest of ways.
Diddling- or the abstract idea conveyed by the verb to diddle- is sufficiently well understood. Yet the fact, the deed, the thing diddling, is somewhat difficult to define. We may get, however, at a tolerably distinct conception of the matter in hand, by defining- not the thing, diddling, in itself- but man, as an animal that diddles. Had Plato but hit upon this, he would have been spared the affront of the picked chicken.
Very pertinently it was demanded of Plato, why a picked chicken, which was clearly "a biped without feathers," was not, according to his own definition, a man? But I am not to be bothered by any similar query. Man is an animal that diddles, and there is no animal that diddles but man. It will take an entire hen-coop of picked chickens to get over that.
What constitutes the essence, the nare, the principle of diddling is, in fact, peculiar to the class of creatures that wear coats and pantaloons. A crow thieves; a fox cheats; a weasel outwits; a man diddles. To diddle is his destiny. "Man was made to mourn," says the poet. But not so:- he was made to diddle. This is his aim- his object- his end. And for this reason when a man's diddled we say he's "done."
Diddling, rightly considered, is a compound, of which the ingredients are minuteness, interest, perseverance, ingenuity, audacity, nonchalance, originality, impertinence, and grin.
Minuteness:- Your diddler is minute. His operations are upon a small scale. His business is retail, for cash, or approved paper at sight. Should he ever be tempted into magnificent speculation, he then, at once, loses his distinctive features, and becomes what we term "financier." This latter word conveys the diddling idea in every respect except that of magnitude. A diddler may thus be regarded as a banker in petto- a "financial operation," as a diddle at Brobdignag. The one is to the other, as Homer to "Flaccus"- as a Mastodon to a mouse- as the tail of a comet to that of a pig.
Interest:- Your diddler is guided by self-interest. He scorns to diddle for the mere sake of the diddle. He has an object in view- his pocket- and yours. He regards always the main chance. He looks to Number One. You are Number Two, and must look to yourself.
Perseverance:- Your diddler perseveres. He is not readily discouraged. Should even the banks break, he cares nothing about it. He steadily pursues his end, and
Ut canis a corio nunquam absterrebitur uncto.
so he never lets go of his game.
Ingenuity:- Your diddler is ingenious. He has constructiveness large. He understands plot. He invents and circumvents. Were he not Alexander he would be Diogenes. Were he not a diddler, he would be a maker of patent rat-traps or an angler for trout.
Audacity:- Your diddler is audacious.- He is a bold man. He carries the war into Africa. He conquers all by assault. He would not fear the daggers of Frey Herren. With a little more prudence Dick Turpin would have made a good diddler; with a trifle less blarney, Daniel O'Connell; with a pound or two more brains Charles the Twelfth.
Nonchalance:- Your diddler is nonchalant. He is not at all nervous. He never had any nerves. He is never seduced into a flurry. He is never put out- unless put out of doors. He is cool- cool as a cucumber. He is calm- "calm as a smile from Lady Bury." He is easy- easy as an old glove, or the damsels of ancient Baiae.
Originality:- Your diddler is original- conscientiously so. His thoughts are his own. He would scorn to employ those of another. A stale trick is his aversion. He would return a purse, I am sure, upon discovering that he had obtained it by an unoriginal diddle.
Impertinence.- Your diddler is impertinent. He swaggers. He sets his arms a-kimbo. He thrusts. his hands in his trowsers' pockets. He sneers in your face. He treads on your corns. He eats your dinner, he drinks your wine, he borrows your money, he pulls your nose, he kicks your poodle, and he kisses your wife.
Grin:- Your true diddler winds up all with a grin. But this nobody sees but himself. He grins when his daily work is done- when his allotted labors are accomplished- at night in his own closet, and altogether for his own private entertainment. He goes home. He locks his door. He divests himself of his clothes. He puts out his candle. He gets into bed. He places his head upon the pillow. All this done, and your diddler grins. This is no hypothesis. It is a matter of course. I reason a priori, and a diddle would be no diddle without a grin.
The origin of the diddle is referrable to the infancy of the Human Race. Perhaps the first diddler was Adam. At all events, we can trace the science back to a very remote period of antiquity. The moderns, however, have brought it to a perfection never dreamed of by our thick-headed progenitors. Without pausing to speak of the "old saws," therefore, I shall content myself with a compendious account of some of the more "modern instances."
A very good diddle is this. A housekeeper in want of a sofa, for instance, is seen to go in and out of several cabinet warehouses. At length she arrives at one offering an excellent variety. She is accosted, and invited to enter, by a polite and voluble individual at the door. She finds a sofa well adapted to her views, and upon inquiring the price, is surprised and delighted to hear a sum named at least twenty per cent. lower than her expectations. She hastens to make the purchase, gets a bill and receipt, leaves her address, with a request that the article be sent home as speedily as possible, and retires amid a profusion of bows from the shopkeeper. The night arrives and no sofa. A servant is sent to make inquiry about the delay. The whole transaction is denied. No sofa has been sold- no money received- except by the diddler, who played shop-keeper for the nonce.
Our cabinet warehouses are left entirely unattended, and thus afford every facility for a trick of this kind. Visiters enter, look at furniture, and depart unheeded and unseen. Should any one wish to purchase, or to inquire the price of an article, a bell is at hand, and this is considered amply sufficient.
Again, quite a respectable diddle is this. A well-dressed individual enters a shop, makes a purchase to the value of a dollar; finds, much to his vexation, that he has left his pocket-book in another coat pocket; and so says to the shopkeeper-
"My dear sir, never mind; just oblige me, will you, by sending the bundle home? But stay! I really believe that I have nothing less than a five dollar bill, even there. However, you can send four dollars in change with the bundle, you know."
"Very good, sir," replies the shop-keeper, who entertains, at once, a lofty opinion of the high-mindedness of his customer. "I know fellows," he says to himself, "who would just have put the goods under their arm, and walked off with a promise to call and pay the dollar as they came by in the afternoon."
A boy is sent with the parcel and change. On the route, quite accidentally, he is met by the purchaser, who exclaims:
"Ah! This is my bundle, I see- I thought you had been home with it, long ago. Well, go on! My wife, Mrs. Trotter, will give you the five dollars- I left instructions with her to that effect. The change you might as well give to me- I shall want some silver for the Post Office. Very good! One, two, is this a good quarter?- three, four- quite right! Say to Mrs. Trotter that you met me, and be sure now and do not loiter on the way."
The boy doesn't loiter at all- but he is a very long time in getting back from his errand- for no lady of the precise name of Mrs. Trotter is to be discovered. He consoles himself, however, that he has not been such a fool as to leave the goods without the money, and re-entering his shop with a self-satisfied air, feels sensibly hurt and indignant when his master asks him what has become of the change.
A very simple diddle, indeed, is this. The captain of a ship, which is about to sail, is presented by an official looking person with an unusually moderate bill of city charges. Glad to get off so easily, and confused by a hundred duties pressing upon him all at once, he discharges the claim forthwith. In about fifteen minutes, another and less reasonable bill is handed him by one who soon makes it evident that the first collector was a diddler, and the original collection a diddle.
And here, too, is a somewhat similar thing. A steamboat is casting loose from the wharf. A traveller, portmanteau in hand, is discovered running toward the wharf, at full speed. Suddenly, he makes a dead halt, stoops, and picks up something from the ground in a very agitated manner. It is a pocket-book, and- "Has any gentleman lost a pocketbook?" he cries. No one can say that he has exactly lost a pocket-book; but a great excitement ensues, when the treasure trove is found to be of value. The boat, however, must not be detained.
"Time and tide wait for no man," says the captain.
"For God's sake, stay only a few minutes," says the finder of the book- "the true claimant will presently appear."
"Can't wait!" replies the man in authority; "cast off there, d'ye hear?"
"What am I to do?" asks the finder, in great tribulation. "I am about to leave the country for some years, and I cannot conscientiously retain this large amount in my possession. I beg your pardon, sir," [here he addresses a gentleman on shore,] "but you have the air of an honest man. Will you confer upon me the favor of taking charge of this pocket-book- I know I can trust you- and of advertising it? The notes, you see, amount to a very considerable sum. The owner will, no doubt, insist upon rewarding you for your trouble-
"Me!- no, you!- it was you who found the book."
"Well, if you must have it so- I will take a small reward- just to satisfy your scruples. Let me see- why these notes are all hundreds- bless my soul! a hundred is too much to take- fifty would be quite enough, I am sure-
"Cast off there!" says the captain.
"But then I have no change for a hundred, and upon the whole, you had better-
"Cast off there!" says the captain.
"Never mind!" cries the gentleman on shore, who has been examining his own pocket-book for the last minute or so- "never mind! I can fix it- here is a fifty on the Bank of North America- throw the book."
And the over-conscientious finder takes the fifty with marked reluctance, and throws the gentleman the book, as desired, while the steamboat fumes and fizzes on her way. In about half an hour after her departure, the "large amount" is seen to be a "counterfeit presentment," and the whole thing a capital diddle.
A bold diddle is this. A camp-meeting, or something similar, is to be held at a certain spot which is accessible only by means of a free bridge. A diddler stations himself upon this bridge, respectfully informs all passers by of the new county law, which establishes a toll of one cent for foot passengers, two for horses and donkeys, and so forth, and so forth. Some grumble but all submit, and the diddler goes home a wealthier man by some fifty or sixty dollars well earned. This taking a toll from a great crowd of people is an excessively troublesome thing.
A neat diddle is this. A friend holds one of the diddler's promises to pay, filled up and signed in due form, upon the ordinary blanks printed in red ink. The diddler purchases one or two dozen of these blanks, and every day dips one of them in his soup, makes his dog jump for it, and finally gives it to him as a bonne bouche. The note arriving at maturity, the diddler, with the diddler's dog, calls upon the friend, and the promise to pay is made the topic of discussion. The friend produces it from his escritoire, and is in the act of reaching it to the diddler, when up jumps the diddler's dog and devours it forthwith. The diddler is not only surprised but vexed and incensed at the absurd behavior of his dog, and expresses his entire readiness to cancel the obligation at any moment when the evidence of the obligation shall be forthcoming.
A very mean diddle is this. A lady is insulted in the street by a diddler's accomplice. The diddler himself flies to her assistance, and, giving his friend a comfortable thrashing, insists upon attending the lady to her own door. He bows, with his hand upon his heart, and most respectfully bids her adieu. She entreats him, as her deliverer, to walk in and be introduced to her big brother and her papa. With a sigh, he declines to do so. "Is there no way, then, sir," she murmurs, "in which I may be permitted to testify my gratitude?"
"Why, yes, madam, there is. Will you be kind enough to lend me a couple of shillings?"
In the first excitement of the moment the lady decides upon fainting outright. Upon second thought, however, she opens her purse-strings and delivers the specie. Now this, I say, is a diddle minute- for one entire moiety of the sum borrowed has to be paid to the gentleman who had the trouble of performing the insult, and who had then to stand still and be thrashed for performing it.
Rather a small but still a scientific diddle is this. The diddler approaches the bar of a tavern, and demands a couple of twists of tobacco. These are handed to him, when, having slightly examined them, he says:
"I don't much like this tobacco. Here, take it back, and give me a glass of brandy and water in its place." The brandy and water is furnished and imbibed, and the diddler makes his way to the door. But the voice of the tavern-keeper arrests him.
"I believe, sir, you have forgotten to pay for your brandy and water."
"Pay for my brandy and water!- didn't I give you the tobacco for the brandy and water? What more would you have?"
"But, sir, if you please, I don't remember that you paid me for the tobacco."
"What do you mean by that, you scoundrel?- Didn't I give you back your tobacco? Isn't that your tobacco lying there? Do you expect me to pay for what I did not take?"
"But, sir," says the publican, now rather at a loss what to say, "but sir-"
"But me no buts, sir," interrupts the diddler, apparently in very high dudgeon, and slamming the door after him, as he makes his escape.- "But me no buts, sir, and none of your tricks upon travellers."
Here again is a very clever diddle, of which the simplicity is not its least recommendation. A purse, or pocket-book, being really lost, the loser inserts in one of the daily papers of a large city a fully descriptive advertisement.
Whereupon our diddler copies the facts of this advertisement, with a change of heading, of general phraseology and address. The original, for instance, is long, and verbose, is headed "A Pocket-Book Lost!" and requires the treasure, when found, to be left at No. 1 Tom Street. The copy is brief, and being headed with "Lost" only, indicates No. 2 Dick, or No. 3 Harry Street, as the locality at which the owner may be seen. Moreover, it is inserted in at least five or six of the daily papers of the day, while in point of time, it makes its appearance only a few hours after the original. Should it be read by the loser of the purse, he would hardly suspect it to have any reference to his own misfortune. But, of course, the chances are five or six to one, that the finder will repair to the address given by the diddler, rather than to that pointed out by the rightful proprietor. The former pays the reward, pockets the treasure and decamps.
Quite an analogous diddle is this. A lady of ton has dropped, some where in the street, a diamond ring of very unusual value. For its recovery, she offers some forty or fifty dollars reward- giving, in her advertisement, a very minute description of the gem, and of its settings, and declaring that, on its restoration at No. so and so, in such and such Avenue, the reward would be paid instanter, without a single question being asked. During the lady's absence from home, a day or two afterwards, a ring is heard at the door of No. so and so, in such and such Avenue; a servant appears; the lady of the house is asked for and is declared to be out, at which astounding information, the visitor expresses the most poignant regret. His business is of importance and concerns the lady herself. In fact, he had the good fortune to find her diamond ring. But perhaps it would be as well that he should call again. "By no means!" says the servant; and "By no means!" says the lady's sister and the lady's sister-in-law, who are summoned forthwith. The ring is clamorously identified, the reward is paid, and the finder nearly thrust out of doors. The lady returns and expresses some little dissatisfaction with her sister and sister-in-law, because they happen to have paid forty or fifty dollars for a fac-simile of her diamond ring- a fac-simile made out of real pinch-beck and unquestionable paste.
But as there is really no end to diddling, so there would be none to this essay, were I even to hint at half the variations, or inflections, of which this science is susceptible. I must bring this paper, perforce, to a conclusion, and this I cannot do better than by a summary notice of a very decent, but rather elaborate diddle, of which our own city was made the theatre, not very long ago, and which was subsequently repeated with success, in other still more verdant localities of the Union. A middle-aged gentleman arrives in town from parts unknown. He is remarkably precise, cautious, staid, and deliberate in his demeanor. His dress is scrupulously neat, but plain, unostentatious. He wears a white cravat, an ample waistcoat, made with an eye to comfort alone; thick-soled cosy-looking shoes, and pantaloons without straps. He has the whole air, in fact, of your well-to-do, sober-sided, exact, and respectable "man of business," Par excellence- one of the stern and outwardly hard, internally soft, sort of people that we see in the crack high comedies- fellows whose words are so many bonds, and who are noted for giving away guineas, in charity, with the one hand, while, in the way of mere bargain, they exact the uttermost fraction of a farthing with the other.
He makes much ado before he can get suited with a boarding house. He dislikes children. He has been accustomed to quiet. His habits are methodical- and then he would prefer getting into a private and respectable small family, piously inclined. Terms, however, are no object- only he must insist upon settling his bill on the first of every month, (it is now the second) and begs his landlady, when he finally obtains one to his mind, not on any account to forget his instructions upon this point- but to send in a bill, and receipt, precisely at ten o'clock, on the first day of every month, and under no circumstances to put it off to the second.
These arrangements made, our man of business rents an office in a reputable rather than a fashionable quarter of the town. There is nothing he more despises than pretense. "Where there is much show," he says, "there is seldom any thing very solid behind"- an observation which so profoundly impresses his landlady's fancy, that she makes a pencil memorandum of it forthwith, in her great family Bible, on the broad margin of the Proverbs of Solomon.
The next step is to advertise, after some such fashion as this, in the principal business six-pennies of the city- the pennies are eschewed as not "respectable"- and as demanding payment for all advertisements in advance. Our man of business holds it as a point of his faith that work should never be paid for until done.
"WANTED- The advertisers, being about to commence extensive business operations in this city, will require the services of three or four intelligent and competent clerks, to whom a liberal salary will be paid. The very best recommendations, not so much for capacity, as for integrity, will be expected. Indeed, as the duties to be performed involve high responsibilities, and large amounts of money must necessarily pass through the hands of those engaged, it is deemed advisable to demand a deposit of fifty dollars from each clerk employed. No person need apply, therefore, who is not prepared to leave this sum in the possession of the advertisers, and who cannot furnish the most satisfactory testimonials of morality. Young gentlemen piously inclined will be preferred. Application should be made between the hours of ten and eleven A. M., and four and five P. M., of Messrs.
"Bogs, Hogs Logs, Frogs & Co.,
"No. 110 Dog Street"
By the thirty-first day of the month, this advertisement has brought to the office of Messrs. Bogs, Hogs, Logs, Frogs, and Company, some fifteen or twenty young gentlemen piously inclined. But our man of business is in no hurry to conclude a contract with any- no man of business is ever precipitate- and it is not until the most rigid catechism in respect to the piety of each young gentleman's inclination, that his services are engaged and his fifty dollars receipted for, just by way of proper precaution, on the part of the respectable firm of Bogs, Hogs, Logs, Frogs, and Company. On the morning of the first day of the next month, the landlady does not present her bill, according to promise- a piece of neglect for which the comfortable head of the house ending in ogs would no doubt have chided her severely, could he have been prevailed upon to remain in town a day or two for that purpose.
As it is, the constables have had a sad time of it, running hither and thither, and all they can do is to declare the man of business most emphatically, a "hen knee high"- by which some persons imagine them to imply that, in fact, he is n. e. i.- by which again the very classical phrase non est inventus, is supposed to be understood. In the meantime the young gentlemen, one and all, are somewhat less piously inclined than before, while the landlady purchases a shilling's worth of the Indian rubber, and very carefully obliterates the pencil memorandum that some fool has made in her great family Bible, on the broad margin of the Proverbs of Solomon.

you don't put a copy of the article up because it may be /.ed if its in a place like ee times, doing it to begin with is karama whoreing if not done as an AC, this is just bullshit..
It usually makes me ejaculate.
There maybe a BIG problem with quantum computers in that they may not be adequately shielded from mental intent. What I mean by this is those mind over matter psychokinetic phenomena found in ESP experiments on random event generators that run on atomic processes. This stuff is real, (don't listen to the wacko "skeptics" about this, they're either uninformed or just plain lie), and systems could be crashed by concentrating for a larger amount of 1s or 0s to occur.

Conquering the Amazon
My freshmen semester I met this girl in my math class. She was a big girl, not fat, just big. She was about 5'11 but not fat. She had a pair of huge knockers; I think they were like E's.
I had been dating a longtime girlfriend when I met her. She was all over me, but I resisted and she wanted me all the more. One night after I broke up with my girlfriend I was doing some serious drinking, and the Amazon (as me and all my frat bros called her) just happened to stop by our house.
I decided that I needed to conquer the Amazon. One thing led to another and I found myself in my room with her. Before I knew it she was naked and giving me one the best blow jobs that I have ever had.
I was very drunk and when I am drunk I get a little mean. When i was about to shoot i pulled out and gave her a surprise facial. I expected some sort of repulsion or anger but instead she wiped all the love juice off her face and put it in her mouth. She smiled and said "God, I love sperm!" She then licked me clean and the dead was done.
I still talk to the Amazon, but now have no respect for her.

The Stinky Slide
Last semester, my fraternity held an end-of-the-year party at one of our brothers' houses. It was a pretty wild night, but the real fun came the next day.
After driving home and sleeping for a while once I got home, I went online and started to talk to one of my brothers who was at the party the night before. He said:
"Yo, you'll never guess what just happened. I'm driving home and I have to take a big ass shit. So I'm holding it in and holding it in, until I finally get home. Now remember, I'm still drunk from last night. S0 I run in my house as fast as possible and head for the bathroom. Remember, I'm still drunk. So I bust in the bathroom and am practically pulling my pants down as I'm running. As I go to sit down on the toilet, my ass slides off the toilet and I fall and shit all over the floor."
At this point I am on the floor laughing. He proceeds to tell me that he sat there for a few seconds pondering what the hell to do about this mess. So he cleaned it all up just before his dad got home to see the mess. Now that's what I call a sobering experience.

Going Out with a Bang
Yes, it is I and I is he, the author of other great Temple classics such as "The Man Whore" and "Legend in the Making" and I have returned to let everyone know how the rest of the semester went since I'm done for good in two days. There are a lot of other great moments, but I finally gave in the title, which you will all hear about. People are still in shock about the given-up title at school and back home.
Don't get it fucked up: my Temple squad and I are still up to no good because we've discovered that after 3:00 am on any given night you can probably kill someone on campus and not get caught, so we discovered some new shit to do for fun. As if the Forman feast wasn't enough, we had one last cookout last week. Seriously the cafeteria inventory must be down at least a few thousand dollars. We had about a dozen or so of hot dogs, chicken, hamburgers, anything you needed we had, along with about a combined total of 3-4 trashbags full of cookies, chips, and other miscellaneous snacks...basically we had our own deli in operation.
We also decided that because I was graduating and everyone else was leaving too, it was imperative that we took a little something along with us to remember all the fun we had. Since I'm only about 5'9 155 pounds wet, my bigger friends helped me up the 15 foot poles to retrieve six Temple flags for each one of us that went out on the mission.
Before I forget, this goes hand and hand with the Forman feast--anyone knows that after a good feast there's nothing like some good desert to wash all that shit down. How about that shit, there just happened to be a vending machine right across from where we cooked up all our food, so you know where this is going, we discovered that if you bend a hanger properly with a nice hook on the end it is possible to actually reach in where all the food is, once you hook onto the spirals where the food is let out, give it one nice yank and out comes the whole spring and about 7 candybars, how about that shit?
What else? Oh yeah, like smoking weed in the bathroom isn't dumb enough I decided that the men's bathroom is only good for having great sex at 11:00 at night, when all your boys are in your room playing Playstation. We left the dorm hallway for smoking weed and outside of our hall as well, a little more riskier. Also, I don't think I've ever used the study lounge this semester except to go fuck all over it, but hey, some sucker is sitting in our mess studying, haha.
The game is still untouchable, I'm still running shit, but this time I went solo. Even though me and my buddy are "best friends" we've decided to do our own thing and run our own shit separately. But that's ok when we have "big dawgs night out" where you plan to blow at least $65 and not think twice of it, we have to go by ourselves, cause to us, money ain't a thang, and $65 to a normal college student is a hell of a lot of money. Or at least an 1/8 of some good fuckin kind bud.
Speaking of weed, a couple other people and I decided to break into someone's car in the parking lot and bake their car out with a fat ass blunt, lucky mother fucker. Oh yeah, and about class, this semester was a straight bitch, I must of missed at least 30 classes this semester alone, but still how managed to do good with 3 writing intensive classes and 2 electives, mostly all senior classes, but here's the real kick in the balls to everyone.
The whole title situation, I definitely gave in the belt this time. Like I said in "I'm the Manwhore," I got with 5 girls in like a month and a half, well, fuck 3 cause 5 is the charm. Yes, believe it or not I definitely found that one that is worth being good to. I'm sure I missed a lot of shit that happened this semester that I can't write about because I'm always with my girlfriend, but I've done enough shit so that it weighs out, it's like Bonnie and Clyde...you know any good drug dealer has a hooked up car with a system that makes pavements crack, and because she smokes as much as I do we get baked and go out at 3:00 am every morning and ride through the quiet suburbs waking every family up whose house I ride by, as I violently scream "Wake the fuck up," yeah she's definitely that girl that no other bitch can come close to. One luv baby.
Well here it is the last two days of my college life, I'm sort of glad though, it's time to go out and make that money the legitimate way and not worry about selling anymore, besides I don't think there is anything else I could possibly accomplish at Temple University that hasn't been done, five years of bullshit classes finally at an end, but it's not like I went anyways.

The Bitch with Butt
I be dancing in this joint right? When I saw this fly honey who was shakin' her ass so I asked her, "Yo honey why you shaking that ass?" She said "Cause somebody needs to shake it."
I took one look at that ass shakin then I squeezed it real tight. You know what that bitch did? She turned around and slapped MY ass. So I slapped her right back. Then she slapped me even harder. This really pissed me off so I busted her right in the chops. I said, "Please bitch," then I went and sat down to have me another drink.
Pretty soon the cops showed up. They told me they were looking for some guy who physically abused some chick right. I told then that I hadn't seen nothing like that cause I hadn't. Then some white boy pointed me out saying it was me or something. I knew they blamed me cause of my skin color so I took off running, see.
So I was running down the street right with three cops behind me when I that chick with the ass came out of no where and got in my way. I bumped into her and almost tripped, so I turned and slapped her again saying, "Please bitch get out of my way."
Then suddenly the cops caught up and tackled my ass. They threw me on the ground. I kept yelling that I was innocent see but they nailed me anyways cause I'm Chinese. I spent a night in jail all cause some chick with a nice ass got in my way. If I ever see her again I'll kick that bitch in the face.

Cheating in the Open
During my (second) senior year, I was taking this horrifying Probability course with my good buddy G-Dog who happens to be a math major. He is also a major wise-ass.
So the course is horrible and no matter how much we study, our grades go steadily down. We both pulled low 20's on the third test. Convinced we were both going to fail the course, we studied minimally for the final. The big day comes and the guy hands out the test. He allowed us one sheet of notes. My friend proceeds to take out the book, a few rented books, his notes, each test, each homework assignment, and a few back tests. He spreads them out and starts the test.
After a short while the professor made his way to where we were sitting and says, "Mr Holliday, I clearly stated you can use one sheet of notes. What are you doing?" G-Dog looks at him, pauses and says the best thing I have ever heard:
"Well Professor, I think its fairly obvious, to even the most simple minded individual, that I am cheating. A lot. Next question?"
The professor was at a loss for words. So G-Dog goes "Oh I'm just razzin' ya." He then puts the stuff away and finishes the test early. He didn't even attempt half of those problems he later told me. He gets up, hands in his test, packs up and goes home since it was his last for the semester.
He failed. I pulled a 'D' for 'Done'.

Bad Idea Hook Up
My dorm is sort of known as the Drunk Tank. I have a single, so whenever my friends are plastered after a party we all go back there and hang out.
So after one uneventful night we made it back to my room, ordered some pizza, and just hung out--at 4 in the morning there really isn't much else. My friend Cameron was acting really strange, he kept scooching closer to me as we sat on my bed. Now I know that doesn't sound weird, but we were in the beginning stages of a relationship just 2 months prior to this. Suffice it to say we only became friends after that because of all our mutual friends.
Anyway, he pulled out my vodka and started asking if I wanted to share with him, I said no but he was welcome to it. He did drink it, and soon everyone left, except Cameron. He asked if he could stay with me since his roommate was surely having sex, and I said it was no problem.
We crawled into my bed, me in the bed, and him atop the covers. I invited him in, since there was no reason for him to sleep like that. So we were just laying there when he had his brilliant idea. I'll do this dialogue style.
Cameron: So, what are you doing?
Me: Trying to sleep.
Cameron: Well, do you want to do something?
Me: What are you talking about? (I'm not exactly the most perceptive kid)
Cameron: Well, you know...
Me: OH! Don't you think it would be a bad idea considering all our friends, it would get weird.
Cameron: Only if we let it.
Me: I guess. But you are a virgin, are you sure you want your first time to be this way?
Cameron: Yeah, it'll be great.
Me: Uh, I guess
So Cameron kissed me, and let me just say, worst kisser ever! I can't even begin to describe it. He bites your teeth, he sticks his tongue in your mouth and just leaves it there, and then there is my personal favorite: the fish where he opens and closes mouth and that's it.
I think my favorite part of the night had to be when, mid-coitus, he actually said (referring to my kissing) that it wasn't working and we should stop! Cameron called me a bad kisser.
I was upset that our previous relationship hadn't escalated until that night.

Pulled Over at Mardi Gras
Some of my friends and I went to Louisiana for Mardi Gras a few years ago. Three of may friends and I drove down there for a couple of days.
The first night I don't really remember and the second night was worse. The third night I'll never forget! My friends and I were driving to our hotel about 4 am. in my S.U.V. and I was swerving all over the road, and my friends were still drinking in the back. All of a sudden cop sirens go off to pull me over. Shit. I was plastered and my friends were puking out the window.
Could it get any worse? Hell yea it could! The policemen comes to my window and looks me in the eye and asks if were drunk. I couldn't lie; it was obvious. Then he asks if the open containers were ours, and my friend slyly, blurts our "No, we stole this car." The policemen then asks for my registration and license, which I don't have. It seemed I lost my wallet in one of the bars, or street. My registration seemed to have been missing. The policemen then got tired of fooling with us and let us off with a warning.
Thank God!

Sneaking Into Class
One day I was walking around campus, skipping class as usual when I had a strange urge to learn. I proceeded into the nearest classroom which happened to be an advanced psychology class, and sat down. I did this for several days, and psychology was the only class I attended. In fact, I didn't even get credit for it.
At the end of that week, the proffessor called me over. (He knew my name-HAHAHA). He told me that if I didn't pay for the class that he would go to the dean. I slipped him a twenty and told him to keep his mouth shut. He did and I attended psychology for the rest of the semester. I guess I'm sort of an idiot because I went to all that trouble to go to that class and didn't get credit for it. Meanwhile, the classes I would have received credit from are the ones I skipped. Isn't that crazy?

Do it all Night, IN THE GHETTO
Fuck.
I hate it when a good joke gets modded "Off-topic" because one person doesn't get it.
Physics: Making the universe open source.
OK, let me see if I've got this straight:
Quantum computing is just around the corner. Blind people can get optical implants directly into their brains, allowing them to recover sight. (Not perfect today, but just wait 'til Moore's law gets hold of this hardware.) It may be possible to build a space elevator within the next 15-20 years. And so on, and so on.
The singularity is suddenly looking a lot less theoretical.
Mostly be corrected? Am I the only one for whom this does not sound particularly reassuring...or usefull?
Most experts would bet a lot of money on the *exact opposite* of what you just wrote.
Quantum computers almost certainly cannot solve NP-complete problems in polynomial time. Despite years of research, factoring couldn't be shown to be NP-complete, which is probably not a coincidence.
I truly take pride in this discovery... mostly because I attend UW. But I suppose a love of physics helps in that area, too.
Anyways, here's a somewhat technical article regarding the research (PDF).
Oh, and "On Wisconsin!"
IWARS.
People, in general, disappoint me. Politicians even more so.
You could run a Beowulf cluster on one machine.

Ok... "Imagine a beouwulf cluster
despite the fact that most of us who read this post have at best a vague understanding of what the prospect of quantum computing offers, why do the ones who seem to know the most about the subject already have an opinion whether it works or why it won't and how it will affect current technology. the only thing i know for sure is when quantum gear hits the street, most people using them are still thinking like a C64

Quantum computers could render assymetric crypto next-to-useless, and as-such may permenantly set electronic privacy back decades for all but the super-powerful.
Those that claim quantum cryptography will redress this problem don't understand that quantum crypto will likely be even more expensive than secure symmetric cryptography.
In essence, the advent of quantum computers may be the turning point, the point where advances in computer communication are no-longer tools of freedom, but become, once more, tools of the powerful.
ATM I'm porting Apache to this architecture. This suits well with my port of Apache for the TV remote 'n the port for my watch.
Up for "1" and down for "0".
Any technology distinguishable from magic, is insufficiently advanced.
...to break RSA. Specifically, I believe that Shor's Algorithm requires 3n qubits, where n is the number of bits of the number you're trying to factor. Multiply by a factor of five to allow some error correction, and you need about 15k qubits to crack 1024-bit RSA.
I work in the field (still an undergrad, but I'm doing some research), and I had the opportunity to meet Michael Nielsen a little while ago when he visited the Perimeter Institute and the University of Waterloo. Nielsen is one of the two authors of the book you mentioned. Out of curiousity, what university do you go to, Misanthropic?

Have a long hard look at that first link before you ignorantly dismiss this person's opinion.
There is a lot of research into this - the ability for thought to influence the outcome of random calculations and events. It's been years since I looked into any of this, the most common experiment is a depiction of a random number generator that you can make devitate from a true random distribution over time by willing it to do so.
Maybe there's something there, maybe there isn't, but you don't just dismiss or accept it out of hand without looking at experimental evidence yay or nay.
..don't panic
so will this let me invent the HAL 9000? Is this a good thing?
Well, I read the article. I am no expert in quantum dots, but I can tell you this. If it is in fact possible to create this 1024x1024 array, then this is huge.
For starters you can factor any number in the order of 100,000 (binary) digits (not a million, since you have to account for error correction).
Currently, the largest quantum processor is implemenetd using liquid-state NMR. This can go up to 8 qubits. Researchers are proyecting that solid-state could go up to 40. In comparison, this is completely of the charts.
I am inclined to believe that this is reminicent of the cold-fusion fiasco. I could be wrong, they could be right; but their claims are so extraordinary that I would wait to see extraordinary evidence to believe them.
I submitted this story the day after it came out, but I have got a running list of over 20 rejected submissions, at least 15 of them later became /. stories.
It's easier to fight for one's principles than to live up to them.
IIRC, there have been some ideas that quantum computers could be used to more effectively model protein folding than we can now. Perhaps even allow the reverse problem of protein engineering (given a desired protein active site structure, to either find a structure that will fold to it or show that none will) to be tackled.
If course, just like everything else that would be revolutionary, the best things are those we can't think of yet.
I'm dubious of this though. I'll start believing it when I see a 10 by 10 demonstrator array running at a few kilohertz. Until then, it's just a nice idea.
I submitted that link days ago. I must be doing something wrong? Does this thing even work?
...let's not get ahead of ourselves here. What about my flying car? I distinctly remember being promised a flying car, and not a thing about these newfangled "quantum computers" or whatnot. Where are our priorities?
Sometimes I think my sig should be a disclaimer about how my post is probably off-topic or otherwise a waste of valuable energy that must now be converted back into a usable form. It would save me time. You are now 30 seconds closer to your death, and so am I. Sorry bout that.

This computer is definately the TacoSnot 3000
This seems to be a pretty extraordinary claim!
Like Sagan says, people laughed at the Wright brothers; but they also laughed at the Marx brothers. Extraordinary claims require extraodinary proof, and nothing in those links does it for me.
All opinions expressed herein are not my own; I haven't had free will since last year when aliens ate my brain.
I'm pleased as anyone to hear that the folks at U-W have developed an experimental implementation of quantum dot QC. Innovation, at any stage, is great.
That said, have the technology to construct something doesn't mean that the thing will work. A quantum device is much different than a traditional electrical device - quantum devices suffer from "decoherence" or a loss of information from the "qubits" to their surrounding environment. This process is EXTREMELY sensitive, and a huge limitation upon QC at the present time. A look at Ike Chuang's book on QC, and you'll see that nearly every implementation of QC is decoherence-limited in some way (quantum dots included).
The Dot people are also not alone - Prof.'s Monroe and Kielpinski at U-Michigan and NIST, respectively, have published a similar paper for ION TRAP-based QC. The ion trap they suggest (a Quantum CCD) is feasible to construct but immensely difficult to operate in practice. Prof. Chuang has produced a WORKING QC on a small scale in NMR. Simply suggesting a means to produced a trap is not enough to suggest working, large-scale QCs are around the corner.
Port Apache + SSL to this architecture while you're at it?
You know that people won't be happy if you take away their ability to transmit webpages securely
The Princeton links states:
" to pursue rigorous scientific study of the interaction of human consciousness with sensitive physical devices, systems, and processes common to contemporary engineering practice."
Why does the study assume that "sensitive" physical devices are easier to affect by thought than larger devices? The more sensitive the device, the more chance other external factors (even small unmeasureable ones -- unrelated to the mind) can easily affect the device -- thus giving the illusion that maybe the mind did it because we don't know what really affected it.
Yes, obviously a lot of research has gone into it. But what about the results. Do researchers keep statistics about the times they DON'T find what they're lookin for? The 13-year-old project still sounds very ethereal.
(Maybe the different machine/people effects produced by different people are due to bad breath rather than the mind -- ask them to move further away from the sensitive machines).
Doesn't Windows make your computer a quantum computer?
You never know its stability state until you attempt an operation. Upon doing so you can't tell what it will do next.

As for the use of quantum computers in AI - at present, nobody has provided an example of a vaguely AI-related problem that quantum computers of the type currently being studied would be useful for. Somebody may do so in the future, of course. In any case, anything that can be done on a quantum computer can be simulated on a normal one (in a theoretical sense, it may take till the end of the universe to do so). They don't give you the ability to compute anything "non-algorithmic".
Any sufficiently advanced technology is indistinguishable from a rigged demo
--Andy Finkel (J. Klass?)
I thought it was very difficult to simulate a quantum computer on a classical computer. Some problems in quantum mechanics can't be properly simulated by a classical system at all.
Once you go past a certain number of qubits, it takes too long to simulate all the possible interactions.
Not that I don't believe we'll see a working quantum co-processor in the next few decades, I'm positive we will.
But I'm just wondering how they came up with the "million qubits" number.
gee, google on "shor's algorithm" gave me many relevent hits. you can read a good explanation and find the relevent paper.
These so called "skeptical" remarks thus far are amature night (i.e. stupid)!
To better educate the parapsychologically illiterate, please have a look at one book that will get you up to speed on this field and give an expose on so called skeptics like Carl Sagan and the organizations he belonged to like CSICOP.
CSICOP and the like, are basically P.R. and propaganda groups that DEBUNK anything that threatens materialist "philosophy." They're not real skeptics but parapsychologist are, and they easily deal with the arguments of these clowns. But you'll have to read the literature to see that. You won't get this by dialing 1-900-psychic.
Here's the book. It's called "The Conscious Universe" by Dean Radin.
Extraordinary claims require extraordinary evidence my ass. Claims should all require very good evidence whether extraordinary or not.
Extraordinary evidence is just another way of saying an amount of evidence so great that it's beyond human ability to achieve. It sets up an humanly impossible standard of evidence that can't be achieved by anyone. Also, it's double standard, "ordinary" ones don't only "extraordinary" ones do. Nice trick to keep a dogma in place. They learned this one from medieval Christian Church.
The fact of the matter is that parapsychological studies far exceed in quality the research done in virtually all other sciences. Recent investigations show that about 90% of their studies are of high quality while the highest amount the conventional sciences get is around 10%. It's usually just a bit over 5% and physics is the worst of the bunch.
As for alternative explanations, read the studies and try to come up with some. GOOD LUCK!
and you have a small dick, QED
Like, a guy posted something about QC's being helpful in understanding protein folding; I think it could be much more than that. A good way of simulating atomic interactions, without ignoring their quantum aspects, could be revolutionary for any industry that works on the atomic-scale.
These industries include biotech and medicine, chip design, MEMS, all kinds of materials science, nanotech, superconductivity research, how-to-wind-nanotubes-into-space-elevator-cable research, and, yes, how-to-build-better-quantum-computers research.
I thought hidden variables was considered to have been disproven...?
Export controls.
You think any government is gonna let anyone but governmental agencies and maybe academic institutions get their hands on a QC for the foreseeable future?
There is no gravity...the earth just sucks.
Well the greatest computer can "compose a sonnett","cook an egg,"calculate PI to a very large place","say I love you","run a mile","come up with E=mc^2","Ask 'who am I?'". With one of it's design specs being "mostly". Sounds "useful" if not always "reassuring".
...will quantum-computer only have a virus if anti-virus programs look?
The race isn't always to the swift... but that's the way to bet!
think again: What he's saying is that factoring is NOT NP complete. Since the original post claimed quantum computers can solve NP complete problems in polynomial time, a paper about factoring has nothing to do with this.
Be wary of any facts that confirm your opinion.
Aside from Shor's factoring algorithm, there is also Grover's searching algorithm that lets you do linear search in slightly less than linear time, and apparently an algorithm for doing quantum physics simulations (surprise surprise). That's it. Three algorithms which work better on a quantum computer. None of them seem much use for Cyc at first glance.

Wouldn't quantum computers help to solve the minefield problem, or prohaps the traveling sales man problem.
minefield can be represented as a sudo logic statement like so
if you had
0 2 b
0 3 c
A 2 d
as a sample the logic would be
(B & C) & ( ( C & D ) | (A & D) | (C & A)) &
((B & C & D ) | ( A & C & B ) | (C & D & A ) | ( D & A & B )
)
you can run this and produce a truth table for the pattern. which you can use to work out where the mines are, where they arn't and where they might be.

Of course, if that's the case, an interesting question comes to light: how acurate and predictive are these simulations, that they would be able to predict quantum effects? Does anyone know anything about this sort of "simulated research?"
credo quia absurdum
I have heard suggestions that alternative designs for quantum computers would theoretically be able to tackle the TSP (or indeed any NP-complete problems) but from what little I know about the area I don't believe anybody's come up with a vaguely plausible way such a computer might be constructed.

Well, nearly there. It seems we're getting to the point where computers will at least have megaquads soon (quad == quantum dot). Will it take another 3 centuries to reach gigaquads?
Now your just making up fake stats.
It's always fun to see the length that these so called skeptics go to when threatened. Hey, lets face it, materialism is dead without psi, the inexplainability of consciousness (subjective experience, etc.) discredits this view already and psi amoung other things is just another nail in an already closed coffin. The only reason for the anger is FEAR. Some maybe from loss of power in society others from loss of face.
My first computer was made out of a process that has acheived Megahertz speeds. The VIC-20
It ran at about 1MHz. Maybe they should start by building a quantum VIC-20 and work their way up the scale again. A quantum 64 with quantum SID, and so on...
So if this is for real, RSA will soon be dead. Does there exist a quantum algorithm for solving the discrete logrithm problem in manageable time?

Have a long hard look at that first link before you ignorantly dismiss this person's opinion.
Fine. I took a pretty good look at that first link. I hereby informedly dissmiss his oppinion. I had to dig to find http://www.princeton.edu/~pear/publist.html with the actual reports with data. I read two, #10 and #11 (selected at whim after skimming titles).
First of all almost all of the results came up negative. They refer to results below average as "negative results", but any result below statitical signifigance is actually a negative result. Second: in #10 *think* I caught them using 1-tail signifigance test in some places they should have used 2-tail tests. If so, that would switch some "postive" results into "negative" results. Third: in #11 I *think* they improperly included incomplete runs for parts of the analysis while excluding them from other parts. This could potentially distort results. Fourth: they cross-analyized the data umpteen different ways actually working to get positive results. If you check sub-sets of the data 20 different ways then one of them should exceed 95% statistical signifigance purely at random. Fifth: In #11 they actually had the gall to throw away half of the data that they didn't like and recalculate the results. When you change the data set after the fact it is trivial to distort the results into fake "statistical signifigance". Sixth: selection bias, negative results are less likey to be published. Seventh: selection bias again, whos bothers reading or linking to papers with negative results?
If there were genuine psychic phenomena the field would explode with scientists. It would explode with military intrest. And perhaps most of all , it would explode with commercial investment/exploitation (chuckle).
By far the largest experiment in the field is the entire casino industry itself. Even the most miniscule effect would become galaringly obvious when you have a sample size probably in the hundreds of trillions (each spin of a slot machine and each bet on the roulette table is a sample).

It'd be great if someone ever succeeds in building a working quantum computer... But don't we need to really understand quantum mechanics first? Nobody -really- understands quantum mechanics.
IMHO, we'll need to learn and understand the unifying theory between classic and quantum physics first. I'm just pessimistic I suppose, but I personally think that quantum computers (as well as cold fusion, Star Trek-esque teleporters, etc.) are never going to venture beyond sci-fi... Not even in a thousand years.
Oh yea... one more thing... I have to apologize for not logging in, I'm just so incredibly lazy.
Either this story has been severely garbled by journalists or its an outright lie designed to get funding.

There you go!
But each spin is an *observation*, not a *sample*.
I'm sure you know the difference, I just
wanted to make it clear for others.
How do I know what I think until I hear what I say?
First of all, get a statistics book or better yet an experimental design book and look at all the data in all of its various catagories. Don't just pick and chose those you like. That's called a biased review. You really do need some help here.
Second, everything you said about casinos and the like you'll eat your words on if you even bother to read the book "Conscious Universe" by Dean Radin. The casino tests have been done and they are in there.
A well known "skeptic" of psi, Ray Hyman (sp?) has said that most responses to psi are very very poor and have been dealt with by parapsychology researchers decades ago. It's really a case of the "poverty of so-called skepticism."
It seems that your looking for powerful effects. The effects at times are but more often at other times are not. But the issue isn't strength like Yoda lifting Lukes space fighter out of the swamp by the power of the "force." It has to do with statistical significance, whether the effect is subtle or not, and also can or can't it be accounted for by other non-psi means. Otherwise, if you dismiss anything subtle as unreal, which can't be justified, you'd have to dismiss electricity when it was first stumbled onto.
Imagine a Beowolf Cluster of THESE!!!
It was a joke.
90% of what are of "high quality?" Experiments investigating unexplainable phenomena?
I'm just calling BS on that statement.(Out of FEAR, of course)
The nice thing about unsubstantiated, extraordinary claims is that you can make them fit anything you want, like horroscopes.
