Andas afurthershort, do not be surprisedeven ifyou do not findanyotherextinctionthattook placeafter 1989andwhose causesarenotfully known. Butlook atthemone by one.
First iteminthelegendof themysteriousdisappearancesconsidered the issueappeared onSeptember 16, 1950. Then, anAmerican journalist, E.V.W.Jonesfirst mentionedthe existence ofunexplainedphenomenaaroundthe Sargasso Sea. Twoyears later, another Americanmediaman, GeorgeX.Sand, publisheda short articleinFate magazine, article onittitled"Sea MysteryAtOurBackDoor" andreferring tosomedisappearancesofshipsandaircraft, including thefamousFlight19that took placein 1945. It was the firsttime someonedraw linestriangleof death. However, they hadto goanother 12years untilVincentGaddis, an obscurejournalistoverseas, calledthemysterious"Bermuda TriangleMortal", a name that hascaused a sensationsinceits appearancein the press, inFebruary 1964.Peoplealreadystarted talkingaboutstrangephenomenain south-eastern United Statesand fromhereuntil aphenomenonwas notonly a step.
Followingbooksby JohnWallaceSpencer(Limbo of the Lost) in 1969, andthat ofRichardWiner(The Devil's Triangle) in 1974, whichhave onlyto raisequestionsandaugmenteda phenomenon thatis already ingrowing. Peakworkswrittenonthe Bermuda Triangleis connectedbuttheappearancein 1974of the booktitledjust"Bermuda Triangle", volume signedby CharlesBerlitz, a former employee ofU.S. militaryspecialservices. Inhis writings, Berlitz, an authoralso acknowledgedfor his passion forthe world's mysteriesandnovelsthat werethe subject ofAtlantis, RoswellIncident, Noah's Ark, PhiladelphiaincidentorRevelation, madea realindictment ofships, submarines, airplanes andevenofyachtsandsmallcraftthateverdisappearedin the Bermuda Triangle. Or, at least, which heclaimedthatdisappeared inthe areaconcerned. The bookhas proveda best sellerandhas sold over20 millioncopies, bringinghima fortuneof CharlesBerlitzneglected, so heturned hisattentionto another"triangle" famousDragon'sTrianglein western Japan, a kind ofyounger brotheroftheAtlantic. Andforloversofeasygainshaveneverlacked, bookstodebate andevenadd otherhundredsofothercasesmentioned byBerlitzbegan to emergeby the dozens. Bermuda Trianglehad becomea businessworth hundreds of millionsof dollars. LawrenceDavidKuschVSCharlesBerlitz Before continuingourjourneythrough thetangledthreadsofdisinformationis necessaryto saya few words aboutthe "father" Bermuda Triangle, CharlesBerlitzAmerican.
Berlitzwas born in NewYork onNovember 20, 1914, thegrandsonof the famousMaximilienBerlitz, founder of theBerlitzSchool ofLanguages. Sinceadolescence,youngCharlesmasteredeightlanguagesperfectly, because thematurityto communicatefluentlyin no morethan32 languages. Infact, American isconsideredtoday, six years after his death, one ofthe greatestlinguistsof all time. After graduating fromYaleUniversity, Berlitzhas beenrecruitedinthe U.S. ArmySpecialServices, where he spentnearly13 years. Afterretirement, hedevoted timeandbooksonunexplainedphenomena, raising a considerable amountofRomanpompoustitlesandcontroversialtopics: AtlantisMysteries, Mysteriesworldsforgotten, Revelation1999,strange phenomenaWorld, Dragon'sTriangle, The Philadelphia Experiment-Projectinvisibility, Atlantis-the lost continent, nowrevealed, just to name a fewofhis famoustitles. Greatshotbutgavethe"Bermuda Triangle" in 1974, a novel that broughtinternationalfameandnearDagHammarskjöldAwardfor more than20 millioncopies.
Yet, there werepeople whoquestioned theveracity ofclaimsbyBerlitz. Oneof themwasLawrenceDavidKusch, a formerAmericanpilotnow thelibrarianinhis hometown ofPhoenix, Arizona. Fascinated bythe subject mattersogenerouslyby CharlesBerlitz, Kusch hasdecidedto take advantageof the service ordedicatedtimeandgather informationonincidentsthat have already becomefamousinarticles and booksweather. Aswas tosaylaterinhis books"Bermuda Triangle mystery-solved" -1975and"disappearanceFlight19"- 1980, Americanwassurprisedto discover thatmany of thecasesdescribed byBerlitzhad beentakenwithoutprior verificationofmostof the authorswhofollowedhispropagandainthe mediaagrosslyfalse. Not onlythat someincidentshad taken placenotin the Bermuda Triangleorthatotherexplanationswerenormalaspossible, butnone of themeverspent.
Kuschpublishedshortly after thehugesuccessof"Trunghiului Bermuda," by Charles Berlitz,a list ofconclusionsthat manyhavetaken itinto accountat the time. Buttimewillvindicatethem:
Numberof shipsandplaneshavedisappearedinDevil's Trianglehas never beenhigher thanelsewhere.
The same numberwasdeliberatelyexaggerated, ignoringtheinformation thatlocalauthoritiescouldprovidethem.
TheBermuda Trianglefrequenttropical stormsoccur, a phenomenonas may beotherwisenormal, which isthe main reasonofthefewmissingclear.
Somedisappearanceshadnever happened, actuallycertifiedasreportsofthearmyandtheportauthorities. CharlesBerlitzandotherwritershaveignoredsimplydatathatwasrecorded in thevesselberthingports, announcingthem astheydisappeared.
The conclusion? BermudaTrianglelegendwas onemadeon purpose,the desire tosell asensationaltopic, andwasperpetuatedtimesfor the same reasons, or unaware of.
Kuschevenbring upthe strength ofthose whostrongly supportthe existence ofunexplainedphenomenabetweenMiami, BermudaandPuertoRico, the famous Flight19.Afterthoroughcheckingofmilitaryrecordsfrom 1945, Americanconcludedthat the disappearanceof fivefighterssquadronwas due tostormsthatdisruptedequipmentonboardtheirprecarious. What was notsaidinanyotherbook aboutthe Bermuda TriangleandFlight19,isthat the planeswere actuallysometraining, all guided bythe mainpilot, Lt. CharlesTaylor. Standardequipmentwithoutjet aircraft, theywouldhave flownerraticallyuntilthey ran out offuel. Thesixthplanesentintheirsearch, which is saidto have disappearedin the same way, actuallyexplodeddue to amalfunctioninone of theengines. Remainsoffiveplanes werediscoveredin the early '90s, in the ocean, only 250kilometers fromFlorida, confirmingthe words ofLarryKusch.
Anotherfamouscase, resumedby anotherobjector's Berlitz, HowardL.Rosenberg, is theSSMarineSulphurQueenship, the shipwhosedisappearanceoccurredon 3 February1963.According toCharlesBerlitz, shipwitha crewof 39sailorssuddenly disappearedfromradarwithoutevenissuingan SOS signal. The onlymaterialevidenceof the"volatilization" cargowas alife jacket,discoveredwhiledrifteda few daysafter the incident. Butheomittedto sayBerlitzSSMarineSulphurQueeniswaswhendisappearance, loadedwith15,000 tons ofliquid sulfur. Sulfurwas depositedin fourhugecontainers, eachheated bya network ofboilersat a temperature of135 degreesCelsius, which makesa realboatfloatingbomb. Berlitzandreportfailed to mentionthe Hondurancoastguard, whosaidthe daythe shipSSMarineSulphurQueendisappearance, alingeringsmell ofsulfurpresentin the coastal area. Most likely, saysRosenberg, the ship explodedfollowing aleakofsulfur, the smallestsparkisable totriggerdisaster. It isobvious thatinsuch a situation, no onehad timeto issueanySOSsignaland if, hypothetically, wouldbeno survivors, theywould have hadno chanceofrescuein the water, full of sharksandbarracuda.
We
conclude our exposure, although the list could go on with dozens of
examples, also a famous case, the disappearance of the submarine USS
Scorpion, during the First World War. Legend
has it suddenly disappeared in the Bermuda Triangle, and the
information obtained after the German army, undoubtedly show that it has
not undergone any underwater shooting. In fact, submarine wreck was discovered by ship USNS Mizar, tests proving that it sank following a technical failure. Moreover, the submarine was found in about 650 miles from the nearest point of the Bermuda Triangle.Conspiracy or mere disinformation? Although
it is obvious massive misinformation regarding the Bermuda Triangle
reality, some of those who challenged legends issued by Berlitz and
other writers have gone even further assumptions. Why
U.S. authorities have never denied their claims and why were content
just to declare that it recognize the existence of the Bermuda Triangle,
that only after 1989 when, in fact, has not gone any ship?Lawrence
David Kusch is perhaps the most radical of all and said the subject was
so ridiculous that no scientist would have stained the name of trying
to prove a truth so obvious. Why would the U.S. government did it?But not everyone believes him. There
were others who argued that both the Bermuda Triangle, and Roswell
incident or the Philadelphia experiment, just to mention a few classic
examples, have been nothing but that famous "bread and circus" meant to
distract people from real problems American nation. A complicit silence that does not involve in any authorities but they solve some problems. In
fact, all these mysteries have emerged during the Cold War, a period of
turmoil in which echoes of conflict between the U.S. and USSR razbateau
hidden from almost all over the world. Perhaps not incidentally, the U.S. position vis-à-vis the Bermuda Triangle came only after the fall of the communist bloc. In fact, the subject was "smoking" and public opinion tended to forget the disappearances of more and more contested. Maybe it was time to show the world stage as a different circus.

Financialmarkets,controlled bysoftwarealgorithms
An important areathathas come to becontrolledlargelyby thealgorithmsisthat offinancialmarkets.
It is estimated thatWallStreet,ina typical day,up to 70% oftransactionshavea computerathome,notan orderplaced bya person.
Because
only a few milliseconds algorithms react to any tendency of market
transactions by them tend to be a growing fraction of total sales and
purchases. A recent report published by Reuters provides evidence of the importance of algorithms in world markets. News
agency reported that in August this year, hedge funds controlled by
computers were able to profit in a volatile market, while funds
controlled by people with negative results. Because
algorithms can perform thousands of transactions over a single minute,
they can take advantage of moments of market instability, rapid response
capability giving them a huge advantage over human brokers. Such
a moment occurred in mid-August, when one of the most popular U.S.
indexes, Dow Jones fluctuated heavily over a period of half past one. In
such moments, most transactions are made of algorithms, according to
Tabb Group, a company specialized in researching and analyzing financial
markets. Ted
Weisberg, one of the brokers on Wall Street, Los Angeles Times
commented on the stock market changes hallucinating: "I think it's great
if you are smart enough that they take advantage of these fluctuations.
But in reality, the market movements are not caused ordinary investors. All these fluctuations are caused by algorithms ". Because
the algorithms react quickly to market movements, there were instances
in which trained heavy snowfall in exchange for no apparent reason. The best known example is the so-called "Flash Crash" of May 6, 2010. Then,
the Dow Jones fell 900 points, equivalent to 9% of the total, the eight
largest companies shares reaching the value of one cent. The
market recovered quickly, the same day, but the financial world was
shocked by the sudden collapse of its actions, and exchange officials
have imposed trading limits, never to allow such algorithms to produce a
fall.

'"
European
Union project designed SARTRE (Safe Road Trains for the Environment),
which aims to develop technologies that will allow cars to form long
convoys on the route. Thus,
only the first vehicle will be actively driven by a driver while the
cars behind it would lead single, chasing her on the front
automatically. The
vehicles will communicate with each other on a special frequency so
that all can respond timely to any decision taken by the driver first
car. EU
claims that this technology will improve traffic, will provide more
comfort for drivers and lead to lower consumption, while reducing the
cost of travel and pollutant emissions. In January 2011, Volvo made its first test of technology, which was a great success: Those involved in the EU project announces that this technology can go into production within a few years. "The more you take, however, acceptance by the public," they stated. According to European statistics, the human factor behind at least 80% of road accidents. As
the cars took control, road trips will become more reliable and secure
wireless communication between machines will reduce traffic jams. Remains to be seen, however, whether drivers will accept to cede control of a software algorithm. "Cruise Control" leads to oblivion As we accept to give up control of your computer, you have to be prepared for the consequences of this decision. A
warning in this regard comes from aviation, where technological
progress has made the autopilot to be so used, that pilots have lost
touch. A
study by the Federal Aviation Administration (FAA) in the U.S. shows
that the pilots "delegated too much responsibility automated systems",
and a large number of security experts say that the number of cases in
which pilots do not know how to react when confronted with disabling autopilot is increasing. Rory
Kay, airline pilot and co-chairperson of the FAA pilot education, told
the Associated Press that he "observed a new type of accident in these
sophisticated aircraft - that the pilots forget how to fly". Skill loss caused hundreds of deaths in aviation accidents in the last five years, experts say. During
this period there were 51 accidents in which planes came into tailspin
in flight and pilots could not intervene to fix it. According to the International Air Transport Association (IATA), this type of accident is the most common air. According
to FAA study, pilots were increasingly fewer opportunities to steer
manually to maintain skills, because many airlines and regulatory
organizations discourage or even prohibit pilots off autopilot. "Airline industry suffers from a reliance on automation," said Kay. Another
member of the FAA and airline pilot also, Bob Coffman said that "more
and more airlines report incidents in which pilots wasting time trying
to restart autopilot, you should take control and fly the plane". Under
applicable law, pilots are required to use autopilot altitude between
8900 meters and 12,500 meters, ie the portion that planes spend most
time. Coffman
said that most airlines advise pilots to activate the autopilot at
about 90 seconds after takeoff, the plane rises about 300 meters, and
keep it turned up to 90 seconds before landing. Even so, to strive for greater automation. In
the U.S., the FAA intends to replace air traffic control systems that
rely on radar technology with more accurate, based on GPS. This change will allow the substitution of old used to landing. If
now the speed aircraft must descend for landing, handling time and fuel
consuming, thanks to GPS technology aircraft will be able to make steep
descents, planând. This
new technique will allow more frequent and more frequent landings, even
in adverse weather conditions, the pilots will know the precise
location of other aircraft and ground objects. The only downside of the new methods of land disposal is one that requires the onboard computer control. "These
new procedures should be performed on autopilot, because one sneeze is
enough to ruin everything," said Bill Voss, president of Flight Safety
Foundation, an organization that promotes aviation safety. Thus,
"the pilots' aircraft will continue to guide aircraft to the
destination, but their role is more like that of a programmer than the
image that we all have in mind, that the aircraft with its hydrostatic
drive. Cars and planes are not the only elements of our lives driven algorithms. Recently, they have become a much more intimate guide our life.
