THE FIRST PERSONAL COMPUTER

Can we imagine our selves  without technology? No, in this generation  it is impossible,everything around us bounded with the technological instruction,
Yes, and computer is the main leading device....

On of the most important technological innovations of the twentieth century was the computer. It gradually progressed from an enormous, unwieldy machine to a small personal computer that could be used in offices and at home. A key event in this development was the introduction by the international Business Machine (IBM) company of a new personal computer in 1981.  The computer, named the 5150 was not the first of its breed by any means, but IBM's solid reputation for quality and reliability made it a strong seller and gave the use of  personal computers a powerful boost. they were no longer a trendy fad, but something people increasingly they ought to have.
      IBM had a history in this general field. It created the world first floppy disc in 1967 and in 1975 unveiled its 5100 portable computer, which was probably the first self-contained portable computer system. Around 1980 , the company marketed its Data-master all-in-one desktop word processor. Like the 5100, it was expensive (around $15,000) and sales were low. The 5150 was a different story altogether. It was reasonably affordable at around $3,000 and it offered more memory than its rivals, whose makers promptly began copying it, producing what were initially known as ''IBM clones'' and later simply as PCs. In August 1982, after a year of manufacturing, the two hundred thousandth model was shipped out.
        The first 5150 contained the Intel 8088 CPU, a single floppy disc drive, and 64 KB of RAM and was the brainchild of engineer Don Estridge. The decision to supply the computer with Microsoft's DOS operating system was the foundation for that company's domination of the software market. 

FIRST IRON BRIDGE

Hi, friends today we are going to learn about a interesting topic related with our daily life....
Bridge :
  A structure that is built over a river, railway cross ,mountain tips, junction to allow people and vehicles to cross from one side to the other without losing the time and the communication of daily life to be easier ...

 Today's post related about The World's First Iron Bridge;

When and Where The World's First Iron Bridge Opens?
 >The completed iron bridge first opened one New Year's Day 1781, The bridge spanning the River Severn Gorge near Coalbrookdale, England, was the idea of young architect Thomas Pritchard. He commissioned  Abraham Darbylll, just twenty-nine at the time and a Quaker iron-master--- whose grandfather Abraham Darby l had triggered the industrial Revolution by inventing the smelting of coke powder to make iron -- to build the pioneering design for a single-span, 120-foot (37 m), 378-ton bridge, using massive parts, the largest of which was 70 feet (21 m) long.
       The bridge used iron to mimic traditional woodcarving techniques-- such as mortise and tenon, dovetails, and wedges--to feet join together. Although Pitchard died in 1777, work on the bridge continued, financed by another local iron-master, John Wilkinson. It was completed in 1779, although the approach roads took another two years. No records were kept on the construction, and exact detail remained a mystery until 2002, when a watercolor by Elias Martin was discovered in Sweden showing how it was made. The bridge become so celebrated that a new town, Iron bridge, grew up around it.
        Darby overspent and was in debt for the rest of his life, but the bridge, although over-heavy and subject to cracks around its foundations, survived and is now recognized as a milestone's in the worlds industrialization. in 1987, Iron bridge was declared a World Heritage Site, attracting a tourist industry that celebrates the industrial Revolution.

NOBEL PEACE PRIZE

Hi friends, Me K.R.Ansari(Historical History/).

Today We are going to learn about the History of  Nobel Peace Prize, as we all heard about it but many of us including me don't  know why and where from it come,So my friends through this we are going to know about the foundation of Nobel,  yah it will be very interesting so get started....

What is Nobel peace prize?

The Swedish industrialist Alfred Nobel, The inventor of dynamite, wrote in his will that awards should be given every year to people, who 'in the previous year have done the greatest good for mankind'. This prizes are named after Alfred Nobel and awarded for path-breaking achievements in the field's of medicine,physics, chemistry,and literature---and for excellent services given to great humanitarians like Albert Schweitzer, Martin Luthr King, and Mother Teresa and also to organisations such as the Red Cross and UNICEF of the United nations. In 2006, Mohammed Yunus, a banker from Bangladesh, received the Nobel peace prize. He lent very small amounts of money to poor people----often just 50 Euro----who needed only the small amount to break the cycle of poverty for good. Today, his theory of 'micro-lending' is helping to eradicate poverty in the world. Since 1901, The Nobel prizes are awarded in Oslo every year on December 10, the death anniversary of Alfred Nobel.

SECRET BEHIND THE AMERICAN REVOLUTION

1809 Thomas Paine, guiding light of the American Revolution and on of the most influential thinkers of the age, died in New York City today. Through his writings, Paine inspired and revived the nation's morale during the dark days of America's fight for independence from Britain. His famous pamphlet Common sense, Published in 1776 and including the words, "The cause of America is in great measure the cause of all mankind" sold more than 1,00,000 copies in three months. The American Crisis, published later in the same year, is credited with contributing to America success at the Battle of the Trenton. While in France, Paine wrote the Writes of Man, a defense of the French revolution that earned him the brand "traitor" in his native Britain. Although a supporter of the revolutionary cause, he was oppose to the execution of Louis XVI: this aroused radical suspicions and landed him in the Luxembourg Prison, where the work on the statement of his religious beliefs, The age of Reason, published after his release. 

LET'S MAKE OUR PLANETS AS HUMAN LIVING PLANET

Hi friends, Me K.R.Ansari(Historical History).

A good morning to all of you & also drawing attention to World Environment Day 5 June;

World environment day occurs on 5 June every year, and is the United Nation's important vehicle for empowering overall mindfulness and activity for the for the protection of our environment. World Environment Day seeks to bring to all a heightened awareness and understanding of the Environment and the problem that besiege it.

 A clean environment is essential for human health and well-being. However, the interactions between the environment and human health are highly complex and difficult to assess. This makes the use of the precautionary principle particularly useful. the best known health impacts are related to ambient air pollution, poor water quality and insufficient sanitation.
        Environment related issues that affect our health have been one of the most important triggers that have led to creating an increasing awareness of the need for better environmental management. Changes in our environmental induced by human activities in nearly every sphere of life have had an influence on the pattern of our health. The assumption that human progress is through economic growth is not necessarily true. We expect urbanization and industrialization to bring in prosperity, but on the down side, it leads to diseases related to overcrowding and a inadequate equality of drinking water, resulting  in an increase in waterborne diseases such as infective  diarrhea and air borne bacterial diseases such as tuberculosis.High-density city traffic leads to an increase in respiratory diseases like asthma and many more.
       
          Let's make our planets as human living planet.

PRINTING FROM MOVABLE TYPE (first printing book)

Hi friends, Me K.R.Ansari(Historical History).

 K.R.Ansari(Historical History).

Now my dear friends before getting let I want to share with you something new which I recently collect from revised history; that is about "First Printing Book"
         
    In 1450 Johann Gutenberg, a craftsman and metalworker from Mainz in Germany, took out a loan from financier. He had been experimenting with ways of printing from movable type, using his knowledge of metalworking to produce a method of casting metal type in quantity by means of a hand mold. He needed funds to develop further tools and equipment,including a wooden screw press, oil based printing links, and paper that could take an impression. With the printing press he created from all these elements he was able to start work on his masterpiece, the Gutenberg Great Bible, the printing of which was completed not later than 1455.
      Gutenberg Bible(also known as the forty-two line Bible, because each page had forty-two lines of text) is commonly held to be the first printed book in Europe and marked the beginning of the mass production of books. It probably took a year to produce the first printing of 180 copies of 1,282 pages each. Gutenberg soon had many imitators, and printing press were set up in city after city to produce Bibles, encyclopedias, theological works, histories, and romances to feed an ever-growing appetite for the printed word.
       The invention of movable type has been likened to the birth of the internet. It was the technological breakthrough that powered the dissemination of ideas during the Renaissance and the humanist explosion of learning of the early sixteenth century. In 1999, Time magazine named the Gutenberg printing press the most important invention of the millennium.

The great Scientist EINSTEIN dies today

The great Scientist EINSTEIN dies today

In this 1955 Albert Einstein died in his sleep today at Princeton Hospital, aged 75. Regarded as one of the most creative intellects in human history, Einstein made his greatest contributions to scientific theory before the age of 50, He was awarded the Nobel prize in Physics in 1921, for the photoelectric law and his work in the field of theoretical Physics. His history of relativity,which had in beginnings in as essay he wrote when he was only 16, was verified by the Royal Society of London in 1919. Einstein commitment to world peace and Zionism brought him into conflict with right-wing opinion in his native Germany. When Hitler become Chancellor of Germany in 1933, after Lise Meinter split the atom, he urged on President Roosevelt the importance of US scientist developing an A-bomb ahead of the Nazis, and his recommendation marked the beginning of the Manhattan Project at Los Alamos. The horror of Hiroshima in 1945 shocked Einstein into issuing letters calling for the establishment of world government to prevent future use of the bomb, aware that without his theory of relativity the nuclear age would not have dawned. 

ABEL TASMAN THE EXPLORER...DISCOVER NEW ZEALAND

ABEL TASMAN THE EXPLORER...DISCOVER NEW ZEALAND 

The Dutch explorer Abel Tasman born in 1603, Abel Tasman spent his career in the service of VOC, The Dutch eastv Indian company, when the Netherlands was Europe's preeminent sea-trading power. In 1634 he was second-in-command of an expedition that reached Formosa(Taiwan) . He also made voyages to Japan in 1641 and to Sumatra in 1642. Later that year, Tasman commanded an expedition to find a fabled "southern land" in the Pacific whose existence had never been verified.
            Tasman sighted the west coast of Tasmania on November 24, which he named after Anthony van Diemen, governor of the Dutch east Indies. Intending to sail north,Tasman was blown east by the prevailing winds, and on December 13, he become the first European to see New Zealand's south islands, which he named the Staten land on the mistaken assumption that it was linked to Argentina's Staten Island. Sailing north , one of his ships attacked by the Island Maori Inhabitants, and four of his sailors were killed. Tasman named the spot Murders Bay(Golden Bay).
             In 1644,Tasman mapped Australia's northern coast. He settled Batavia   and become a wealthy leader of Dutch community---his later life marred only when he was find and demoted for hanging a sailor without trial. He Died in 1659.

ONE OF THE MOST DECISIVE BATTLES IN EUROPEAN HISTORY

ONE OF THE MOST DECISIVE BATTLES IN EUROPEAN HISTORY

In 732, on a hilltop between Tours and Poitiers in France, on of the most decisive battle in European history was fought. In the hundred years following ,armies inspired by the Islamic faith had pressed forward through north Africa and the Iberian Peninsula to arrive in the heart of Western Europe. In 732, the governor-general of Muslim Spain, Abd-ar-Rahman al-Ghafiqi, led an army across the Pyrenees and conquered Aquitaine, laying waste to Bordeauxe. He than headed for the kingdom of the Franks, toward the city of Tours.
              The Frankish leader Charles Martel placed his 30,000-strong army on high, wooded ground, in their line of advance. He formed his men into a tight infantry square, and waited. Abd-ar-Rahman al-Ghafiqi held off from attacking from 7 days, although his force may have outnumbered the Franks by two to one. when he finally lunched his cavalry, the Frankish infantry stood firm and repelled their charges. After a long fight, the Muslim horsemen withdrew to defend their war  chests, and abandoned by his men, Abd-ar-Rahman al-Ghafiqi was surrounded and killed.
               It is likely that Abd-ar-Rahman al-Ghafiqi had not sought to coquer European Chsistendom, but just to lead a raidinng expedition. But if the Frankish warriors had lost, nothing would have stood in the way of a Muslim takewover of western Europe. Charls Martel consolidate the Carolingian Empire, which formed a barrier to the northward expansion of Islam.
               

A JOURNEY THROUGH IMPOSSIBLE MOUNTAIN BARRIER TO ATTACK ROME.

A JOURNEY THROUGH IMPOSSIBLE MOUNTAIN BARRIER TO ATTACK ROME.

In the fall of 218 B.C.E., an exhausted,demoralized army lay scattered among the rocks,snow, and ice of a high Alpine pass.A  force of wild tribesmen from Spain , Libyan foot soldiers, and Numidian horsemen from north Africa had followed twenty-eight-year-old general Hannibal Barca in a bid to cross this apparently impossible mountain barrier.
           Hannibal's native city, Carthage, in what is now Tunisia, was engaged in a life-or-death struggle with the Roman republic from control of the western Mediterranean. In the spring of 218 B.C.E., Hannibal had led his army from Spain to Italy. He set out with more than 100,000 men, tens of thousands of horses and mules, and thirty-seven war elephants. A long journey to hostile territory greatly reduced the army even before it reached the Alps. There, advancing up narrow tracks through mountain gorges, Hannibal's soldier were attacked by the Alloroges and other local tribesmen. It took 9 days to reach the top of the pass.
            Hannibal, Who had shared in all his men's hardships, rallied the cold and hungry troops to under tack the descent into Italy, which, he said, would place Rome ion their hands. Walking walking on snow and ice, the animals and men struggled along the narrow downward track, terrified of falling to their deaths over the slippery edge. At one point they had to spend four days rebuilding the obliterated path. Only around 26,000 men made it to Italy, with a handful of elephants. Nonetheless, Hannibal had achieved an extraordinary feet in crossing the Alps and could now advance upon the Rome.  

EUREKA! The Archimedes Discovery While Taking a Bath....how to measure density..

HOW TO MEASURE DENSITY

           King Hieron of Sicily, wanting to find out if a crown he had been given was made of solid gold, or whether he had been palmed off with on containing silver, asked Archimedes to solve the problem. But how was he to do so without melting down the metal and destroying the crown? Interestingly while  taking a bath, Archimedes noticed the water level rose when he got in, and he realized that he could determine the gold density of the crown by weighing it in water. He was so excited by this discovery that he reputed to have rushed out naked into the street shouting "EUREKA!"  ("I have found it") .
                 Archimedes was born in 287 b.c.e. in the Greek city-state of Syracuse, Sicily, and is also credited with inventing the lever and the Archimedes screw - a device for lifting water  - and for setting fire to Roman ships using mirror and sun's rays during the siege of Syracuse.  When the city fell in 212 B.C.E., Archimedes, so it was said, was killed by a Roman soldier because he ignored a commend to leave his mathematical diagrams. Archimedes was held in great respect by the ancient world, both as a practical and theoretical  scientist . He wrote on mechanics, hydro-statics, catoptrics (refraction), and mathematics. Although much of his work is lost, his surviving writings were known to Islamic mathematicians in the middle ages. ................
