NEVER RETURNED FOR CENTURIES .......

 There are many mysteries places in the world. even there are more unknown places in terrestrial. If we lost in any forest or island etc, there is possibility to be found.But, think about space and sea. If we lost in space, there is no way to be founded. In sea there is a chance to be found , only the places humans are mention. but, there are lot of places in the sea were the humans can't imagine.One of a place in north Atlantic ocean were only incoming, no outgoing. Many ships and aircraft have gone, but not returned for centuries.

THE BERMUDA TRIANGLE

THE BERMUDA TRIANGLE is also called as devil's triangle or hurricane alley.It is a  undefined region in the western part of the north Atlantic ocean.Many of the planes and ships vanished by the triangle. One of the most important mystery in the sea.The vicinity of the Bermuda triangle is amongst the most heavily traveled shipping lanes in the world, with ships frequently crossing thought it for port in the Americas, Europe and the Caribbean islands.The ships and aircraft regularly sail through the region, and commercial and private aircraft routinely fly over it.

The gaddis argosy article delineated the boundaries of the triangle, giving its vertices as Miami; San Juan, Puerto Rico and Bermuda. Subsequent writers did not necessarily follow this definition. Some writers gave different boundaries and vertices to the triangle, with the total area varying from 1,300,000 to 3,900,000 km^2(500,000 to 1,510,000 sq mi) Instead, some writers even stretch it as far as the Irish coast. Consequences, the determination of which accident occurred inside the triangles depends on which writer reported them.

Some speculate that unknown and mysterious forces account for the unexplained disappearances, such as extraterrestrials capturing humans for study; the influence of the lost continent of Atlantis; vortices that suck objects into other dimensions; and other whimsical ideas.  Some explanations are more grounded in science, if not in evidence.  These include oceanic flatulence (methane gas erupting from ocean sediments) and disruptions in geomagnetic lines of flux.

Environmental considerations could explain many, if not most, of the disappearances.  The majority of Atlantic tropical storms and hurricanes pass through the Bermuda Triangle, and in the days prior to improved weather forecasting, these dangerous storms claimed many ships.  Also, the Gulf Steam can cause rapid, sometimes violent, changes in weather.  Additionally, the large number of islands in the Caribbean Sea creates many areas of shallow water that can be treacherous to ship navigation. And there is some evidence to suggest that the Bermuda Triangle is a place where a “magnetic” compass sometimes points towards “true” north, as opposed to “magnetic” north [Even the compass won't work properly]. 

The U.S. Navy and U.S. Coast Guard contend that there are no supernatural explanations for disasters at sea.  Their experience suggests that the combined forces of nature and human fallibility outdo even the most incredulous science fiction. They add that no official maps exist that delineate the boundaries of the Bermuda Triangle. The U. S. Board of Geographic Names does not recognize the Bermuda Triangle as an official name and does not maintain an official file on the area.

The ocean has always been a mysterious place to humans, and when foul weather or poor navigation is involved, it can be a very deadly place.  This is true all over the world.  There is no evidence that mysterious disappearances occur with any greater frequency in the Bermuda Triangle than in any other large, well-traveled area of the ocean.If we gone, "NEVER RETURNED  FOR CENTURIES "

GLOW LIKE AS........

 Word of a glowing is amazing like a light. The light that falls on us is a blessing from the sun . which blesses everyday, every minute , every second. No one from this world have unblessed. Light rays falls on the land gives birth to new life. But, at night there is no light ray of sun.  . But a legendary man who gave light to the world.

Early Light Bulbs

In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp. And while it produced light, it didn’t produce it for long and was much too bright for practical use.

Over the next seven decades, other inventors also created “light bulbs” but no designs emerged for commerical application. More notably, in 1840, British scientist Warren de la Rue enclosed a coiled platinum filament in a vacuum tube and passed an electric current through it. The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain fewer gas molecules to react with the platinum, improving its longevity. Although an efficient design, the cost of the platinum made it impractical for commercial production.

In 1850 an English physicist named Joseph Wilson Swan created a “light bulb” by enclosing carbonized paper filaments in an evacuated glass bulb. And by 1860 he had a working prototype, but the lack of a good vacuum and an adequate supply of electricity resulted in a bulb whose lifetime was much too short to be considered an effective prodcer of light. However, in the 1870’s better vacuum pumps became available and Swan continued experiments on light bulbs. In 1878, Swan developed a longer lasting light bulb using a treated cotton thread that also removed the problem of early bulb blackening.

On July 24, 1874 a canadian patented was filed by a Toronto medical electrician named Henry Woodward and a colleague Mathew Evans. They built their lamps with different sizes and shapes of carbon rods held between electrodes in glass cylinders filled with nitrogen. Woodward and Evans attempted to commercialize their lamp, but were unsuccessful. They eventually sold their patent to Edison in 1879.

In 1878, Thomas Edison began serious research into developing a practical incandescent lamp and on October 14, 1878, Edison filed his first patent application for "Improvement In Electric Lights". However, he continued to test several types of material for metal filaments to improve upon his original design and by Nov 4, 1879, he filed another U.S. patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires."

Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," it was not until several months after the patent was granted that Edison and his team discovered that a carbonized bamboo filament could last over 1200 hours.

This discovery marked the beginning of commerically manufactured light bulbs and in 1880, Thomas Edison’s company, Edison Electric Light Company begain marketing its new product.Make him sure "REMEMBER FOR CENTURIES "

WHATS' YOU GUYS THINK OF AUTOMOBILES

   

Hey guys, on that time we use our legs to go far and near by places.but, today we use a vehicle to go every place in the world.it was after invention of the automobile .even too, it make us lazy.what do think before the discovery of automobiles...... 

Leonardo da vinci considered the idea of a self-propelled vehicle in the 15th century. In 1760 a Swiss clergyman, J.H. Genevois, suggested mounting small windmills on a cartlike vehicle, their power to be used to wind springs that would move the road wheel. Genevois’s idea probably derived from a windmill cart of about 1714. Two-masted wind carriages were running in the Netherlands in 1600, and a speed of 20 miles (30 km) per hour with a load of 28 passengers was claimed for at least one of them. The first recorded suggestion of wind use was probably Robert Valturio’s unrealized plan (1472) for a cart powered by windmills geared to the wheels.

Other inventors considered the possibilities of clockwork. Probably in 1748 a carriage propelled by a large clockwork engine was demonstrated in Paris by the versatile inventor jacques de vaucanson 

   

The air engine is thought to have originated with a 17th-century German physicist,otto von guericke . Guericke invented an air pump and was probably the first to make metal pistons, cylinders, and connecting rods, the basic components of the reciprocating engine. In the 17th century a Dutch inventor, christiaan huygens, produced an engine that worked by air pressure developed by explosion of a powder charge. Denis papin of France built a model engine on the vacuum principle, using the condensation of steam to produce the vacuum. An air engine was patented in England in 1799, and a grid of compressor stations was proposed to service vehicles. An air-powered vehicle is said to have been produced in 1832.

Steam propulsion was proposed as early as the 16th century, and in 1678 Ferdinand verbiet, a Belgian Jesuit missionary to China, made a model steam carriage based on a principle suggestive of the modern turbine

LINES OF INFORMATION

 THE INFORMATION OF EACH AND EVERY OBJECT IS IMPORTANT.EACH AND EVERY OBJECT HAVE HISTORY AND INTERESTING NEWS.BUT DAY TO DAY LIFE WE USE SOME PRODUCTS LIKE BREAD TO EAT AND PEN TO WRITE ETC.....THE INFORMATION ABOUT THE THINGS  CAN'T BE EASILY TO HANDLE IN ,BOOKS ,COMPUTERS ,LAPTOP ETC IT TAKE A LOT TIME TO SEARCH ABOUT IT .BUT , TODAY IT IS MORE EASY TO SCAN THE OBJECT S' INFORMATION WITH THE HELP OF BAR CODE.... 

 BAR CODE

Add caption

A BARCODE OR BAR CODE IS WAY OF REPRESENTED DATA IN A VISUAL, MACHINE-READABLE FROM. INITIALLY, BAR CODE REPRESENTED DATA BY VARYING THE  WIDTHS AND SPACINGS OF PARALLEL LINES. THESE BAR CODE REFERRED TO THE ONE DIMENSIONAL [1D] , CAN BE SCANNED BY SPECIAL OPTICAL SCANNERS, CALLED BAR CODE READER. LATER , TWO- DIMENSIONAL[2D] VARIANTS WERE DEVELOPED,USING RECTANGLES DOTS,HEXAGONS AND OTHER GEOMETRIC PATTERNS, CALLED  MATRIX  CODES OR 2D BAR-CODES2D BAR CODE CAN READ OR DECONSTRUCTED USING THE   APPLICATION SOFTWARE IN MOBILE DEVICES, SCANNING BY MOBILE CAMERA.

THE BAR CODE WAS DISCOVERED BY NORMAN JOSEPH WOODLAND AND BERNARD SILVER IN TH US AT THE YEAR OF 1951, THE INVENTION IS BASED ON THE MORSE CODE THAT WAS EXTENDED TO THIN AND THICK BARS. HOW EVER ,IT  THE INVENTION TAKES 20 YEARS TO BE SUCCESSFUL. BUT IN 1960, ONE TYPE OF BAR CODE HAVE USED IN AN INDUSTRIAL CONTEXT WAS SPONSORED BY THE ASSOCIATION OF AMERICAN RAILROADS . IT HELPED IN THE DEVELOPMENT OF GENERAL TELEPHONE AND ELECTRONICS [GTE] AND IT IS CALLED AS KARTRRAK ACI [ AUTOMATIC CAR IDENTIFICATION ] THIS SCHEME INVOLVED PLACING COLORED STRIPES IN VARIOUS COMBINATIONS ON STEEL PLATES WHICH WERE AFFIXED TO THE SIDES OF THE RAILROADS ROLLING STOCK. 

                                                            ONLY TWO PLATES WERE USED PER CAR, ONE ON EACH SIDE, WITH THE ARRANGEMENT OF THE COLORED STRIPES ENCODING INFORMATION  SUCH AS OWNERSHIP,TYPE OF EQUIPMENT , AND IDENTIFICATION NUMBER. THE PLATES WERE READ BY A TRACKSIDE SCANNER , LOCATED FOR INSTANCE, AT THE ENTRANCE TO CLASSIFICATION YARD , WHILE THE CAR MOVING PAST.   THE PROJECT WAS ABANDONED AFTER ABOUT TEN YEARS BECAUSE THE SYSTEM PROVED UNRELIABLE AFTER LONG TERM USE.

                                              

                                           BARCODE BECAME VERY SUCCESSFUL IN SUPER MARKETS TO CHECK THE PRODUCT EASILY. THE UNIFORM GROCERY PRODUCT CODE COUNCIL HAD CHOSEN, IN 1973, THE BARCODE DESIGN DEVELOPED BY GEORGE LAURER .LAURER'S BARCODE WERE PRINTED BETTER THAT THE CIRCULAR CODES DEVELOPED BY WOODLAND AND SILVER.

                                                        THEIR USE HAS SPREAD TO MANY OTHER TASKS THAT ARE GENERICALLY REFEREED TO AS AIDC. THE FIRST SCANNING OF UNNIVERSAL PRODUCT CODE WAS BY WRIGLEY COMPANY CHEWING GUM WERE PRINTED ON THERE PRODUCT IN JUNE 1974 AT A MARSH SUPERMARKET IN TROY OHIO. QR CODE , A SPECIFIC TYPE OF 2D BARCODE HAVE RECENTLY BECOME VERY POPULAR.

POWER OF ATTRACTION

 IN OUR EARTH THERE ARE MANY MYSTERY HAVE BEEN ALIVE TODAY. THERE ARE MORE AMAZING AND UNBELIEVABLE HAPPEN IN PAST.TODAY, WE USE A THING THAT HELP US TO ATTRACT METALS,LIKE SPITTING THE METALS FROM GARBAGE AND LIFT A HEAVY METALED OBJECT ETC......

MAGNES

MAGNES IS A GREEK SHEPHERD BEFORE 4000 YEARS AGO.HE WAS THE FOUNDED OF MAGNETS IN THE YEAR 6TH CENTURY BC. HE WAS GOING WITH A METAL STICK WITH HIS FLOCKS[GROUP OF SHEEP] SUDDENLY HIS SHOE STUCK ON THE WHICH WAS MADE BY METAL.WERE HE WAS CONFUSED THAT HOW THE SHOE CAN STUCK ON GROUND.AND HE TRY BY HIS STICK WERE THE TRIP HAVE A NAIL AND SICKED IN THE GROUND.HE DIG THE GROUND AND HE GOT A STONE THAT WAS LODESTONE,WHICH CONTAIN MAGNETIC POWER.

                                         ACTUALLY , HE DID NOT FOUND THE MAGNET . HE FOUND ONLY LODESTONE. THE FATHER OR DISCOVERY OF WAS WILLIAM GILBERT.HE FOUND THE MAGNET IN THE YEAR OF 1600.HE WAS A PHYSICIAN AND GREAT NATURAL PHILOSOPHER.HE PASSIONATELY REJECTED BOTH THE PREVAILING ARISTOTELIAN PHILOSOPHY AND THE SCHOLASTIC METHOD OF UNIVERSITY TEACHING. HE IS REMEMBERED BY HIS BOOK DE MAGNETE[1600]. HE WAS THE ORIGIN OF DISCOVERY OF ELECTRICITY. ALSO HE IS KNOWN FATHER OF ELECTRICITY. 

A MAGNETS IS A OBJECT THAT PRODUCES A MAGNETIC FIELD. THE FIELD IS INVISIBLE BUT IS RESPONSIBLY FOR MOST OF THE MAGNETIC PROPERTIES.A FORCE THAT PULLS ON OTHER FERROMAGNETIC MATERIALS SUCH AS IRON,AND ATTRACTS OR REPELS OTHER MAGNETS.

PERMANENT MAGNETS

IT IS A OBJECT MADE FROM A MATERIEL THAT IS MAGNETIZED AND CREATES IT OWN PERSISTENT MAGNETIC FIELD. AN EVERYDAY EXAMPLE IS A REFRIGERATOR MAGNET USED TO HOLD THE DOOR OF THE REFRIGERATOR .THE MATERIAL THAT CAN BE MAGNETIZED,WHICH ARE ALSO THE ONES STRONGLY  ATTRACTED TO A MAGNET, ARE CALLED FERROMAGNETIC OR FERRIMAGNETIC .THE METALS ARE IRON,NICKEL AND COBALT AND THEIR ALLOYS, SOME ALLOYS OF RARE-EARTH METALS, AND SOME NATURALLY OCCURRING MINERALS  SUCH AS LODE STONE .ALTHOUGH FERROMAGNETIC MATERIALS ARE ONLY ONES ATTRACTED TO A MAGNET STRONGLY ENOUGH TO BE COMMONLY CONSIDERED MAGNETIC, ALL OTHER SUBSTANCES RESPOND WEAKLY TO A MAGNETIC FIELD,K BY ONE SEVERAL OTHER TYPES OF MAGNETISM. 

FERROMAGNETIC MATERIALS CAN BE DIVIDED INTO MAGNETICALLY"SOFT" MATERIALS LIKE ANNEALED IRON,WHICH CAN BE MAGNETIZED BUT DO NOT TEND TO SAY MAGNETIZED, AND MAGNETICALLY"HARD" MATERIAL,WHICH DO A LONG TIME. PERMANENT MAGNET ARE MADE FROM "HARD" FERROMAGNETIC MATERIALS SUCH AS ALNICO AND FERRTE THAT ARE SUBJECTED TO SPECIAL PROCESSING IN A STRONG MAGNETIC FIELD DURING MANUFACTURE TO ALIGN THEIR 

INTERNAL MICROCRYSTALLINE STRUCTURE,MAKING THEM VERY HARD TO DEMAGNETIZE.TO DEMAGNETIZE A SATURATED MAGNET A CERTAIN MAGNETIC FIELD MUST BE APPLIED,AND THIS THRESHOLD DEPENDS ON CORECIVITY OF THE RESPECTIVE MATERIAL."HARD" MATERIALS HAVE HIGH COERCIVITY, WHEREAS "SOFT" MATERIALS HAVE LOW CORECIVITY. THE OVERALL STRENGTH OF A MAGNET IS MEASURED BY ITS MAGNETIC MOMENT OR, ALTERNATIVELY,THE TOTAL MAGNETIC FLUX IT PRODUCE.THE STRENGTH OF THE MAGNETISM IN A MATERIAL IS MEASURED BY ITS MAGNETIZATION. THERE IS A OTHER MAGNET CALLED ELECTROMAGNET. IT IS MADE BY A COIL OF WIRE THAT ACTS AS A MAGNET WHEN THE CURRENT TRAVEL IN THE COIL.WHEN THE CURRENT STOP IT GET DEMAGNETIZE.WHEN A SOFT OR FERROMAGNETIC MATERIAL SUCH AS MILD STEEL, WHICH PRODUCE MORE MAGNETIC FIELD PRODUCED BY THE COIL.THE POWER OF ATTRACTION IS MORE..........
