Joan of Arc
Born
6 January, c. 1412[1]Domrémy,
Joan of Arc nicknamed "The Maid of Orléans" (French: La Pucelle d'Orléans), is considered a heroine of France and a Roman Catholic saint.
Joan was the daughter of Jacques d'Arc and Isabelle Romée[23] in Domrémy, a village which was then in the French part of the duchy of Bar.[24] Joan's parents owned about 50 acres (20 hectares) of land and her father supplemented his farming work with a minor position as a village official,
She later testified that she experienced her first vision in 1425 at the age of 13, when she was in her "father's garden"[26] and saw visions of figures she identified as Saint Michael, Saint Catherine, and Saint Margaret, who told her to drive out the English and bring the Dauphin to Reims for his coronation
In 1418, Paris was taken by the Burgundians, who massacred the Count of Armagnac and about 2,500 of his followers.[16] The future French king,Charles VII, assumed the title of Dauphin – the heir to the throne – at the age of fourteen, after all four of his older brothers had died in succession.[1
"... the Maiden lets you know that here, in eight days, she has chased the English out of all the places they held on the river Loire by attack or other means: they are dead or prisoners or discouraged in battle.
The sudden victory at Orléans also led to many proposals for further offensive action. Joan persuaded Charles VII to allow her to accompany the army with Duke John II of Alençon, and she gained royal permission for her plan to recapture nearby bridges along the Loire as a prelude to an advance on Reims and the coronation of Charles VII.

Boudica
Died
circa AD 60 or 61, Britannia
Boudica was a striking looking woman. - "She was very tall, the glance of her eye most fierce; her voice harsh. A great mass of the reddest hair fell down to her hips. Her appearance was terrifying
Boudica's husband Prasutagus was ruler of the Iceni tribe. He ruled as a nominally independent ally of Rome and left his kingdom when he died Boudica was flogged, her daughters were raped, and Roman financiers called in their loans.
In 60 or 61 AD, while the Roman governor Gaius Suetonius Paullinus was leading a campaign in North Wales, the Iceni rebelled. Members of other tribes joined them
The Iceni warriors managed to destroy Camulodunum (Colchester) they also defeated the Roman IX Legion.
Hearing the news, Paullinus rushed back from Wales and set about evacuating Londinium (London). He guessed (correctly) that it would be the Britons next target.
Boudicca and her army destroyed Londinium and then attacked Verulamium (St Albans), destroying that city too.
Some people believe that more than 70,000 people were killed in the attacks on Camulodunum,
The Roman army in Britain regrouped in the Midlands and finally defeated the Britons in the Battle of Watling Street.
Roman cavalry was released which promptly encircled the enemy and began their slaughter from the rear. Seemingly mad with blood lust, Tacitus records that 80,000 Britons; men, women and children, were killed. The Roman losses amounted to 400 dead with a slightly larger number wounded.
Boudica was not killed in the battle but took poison rather than be taken alive by the Romans.

Commissioned in 1632 by the Mughal emperor Shah Jahan to house the tomb of his third wife, Mumtaz Mahal, the Taj Mahal stands on the southern bank of the Yamuna River. The mausoleum is widely recognized as "the jewel of Muslim art in India" and remains as one of the world’s most celebrated structures and a symbol of India’s rich history.[6]

Eiffel Tower
Erected in 1889 as the entrance arch to the 1889 World's Fair, it was initially criticised by some of France's leading artists and intellectuals for its design, but has become both a global cultural icon of France and one of the most recognizable structures in the world.[1] The tower is the tallest structure in Paris and the most-visited paid monument in the world; 6.98 million people ascended it in 2011.[2] The tower received its 250 millionth visitor in 2010.[2]
Gustave Eiffel
The projected tower had been a subject of some controversy, attracting criticism from both those who did not believe that it was feasible and those who objected on artistic grounds,
Gustave Eiffel responded to these criticisms by comparing his tower to the Egyptian Pyramids: "My tower will be the tallest edifice ever erected by man. Will it not also be grandiose in its way? And why would something admirable in Egypt become hideous and ridiculous in Paris?
When construction of the tower began on the Champs de Mars, a group of 300 artists, sculptors, writers and architects sent a petition " that would dominate Paris like a "gigantic black smo(continued)

William the Conqueror (c.1028 - c.1087)
Early in 1066, Edward, king of England died and Harold, Earl of Wessex was crowned king. William was furious, claiming that in 1051 Edward, a distant cousin, had promised him the throne and that Harold had later sworn to support that claim.
The first years of William's reign were spent crushing resistance and securing his borders, which he did with ruthless efficiency.

Richard the Lionheart
As king, Richard's chief ambition was to join the Third Crusade, prompted by Saladin's capture of Jerusalem in 1187. To finance this, he sold sheriffdoms and other offices and in 1190 he departed for the Holy Land.
Although he came close, Jerusalem, the crusade's main objective, eluded him. Moreover, fierce quarrels among the French, German and English contingents provided further troubles. After a year's stalemate, Richard made a truce with Saladin and started his journey home

Crisps
George Crum
George Crum (born George Speck;[1] c. 1828 – July 22, 1914)[2] was a mixed-race African/Native American trapper and guide in the Adirondacks, who became renowned for his culinary skills after becoming a cook and restaurant owner in Saratoga Springs, New York. By 1860 he owned Crum's House, a popular lakeside restaurant in nearby Malta.
Hotel chef George Crum enjoyed a wonderful knack for cooking. From his kitchen at Moon's Lake House near Saratoga Springs, N.Y., Mr. Crum could "take anything edible and transform it into a dish fit for a king." That skill came in handy – the upscale Lake House attracted customers who were used to being treated like kings.
In 1853, a cranky guest complained about Crum's fried potatoes. They were too thick, he said. Too soggy and bland. The patron demanded a new batch.
Crum did not take this well. He decided to play a trick on the diner. The chef sliced a potato paper-thin, fried it until a fork could shatter the thing, and then purposefully over-salted his new creation. The persnickety guest will hate this, he thought. But the plan backfired. The guy loved it! He ordered a second serving.
The first potato chip factory was built in 1895 by William Tappenden in Cleveland, OH. He funded the remodeling of his barn into a factory with the profits he made by delivering potato chips to grocery stores.
It takes 1,000 pounds of potatoes to make 350 pounds of potato chips.

Harry Coover
Super Glue, also known as cyanoacrylate, was originally discovered in 1942 by Dr. Harry Coover, who by the way died last month on March 26th, 2011. Coover was attempting to make clear plastic gun sights to be put on guns used by Allied soldiers in WWII. One particular formulation he came up with didn’t work well for gun sights, but worked fantastically as an extremely quick bonding adhesive.
X RAYS
The first X-ray device was discovered accidentally by the German scientist Wilhelm Roentgen (1845-1923) in 1895. He found that a cathode-ray tube emitted invisible rays that could penetrate paper and wood. The rays caused a screen of fluorescent material several yards away to glow. Roentgen used his device to examine the bone structure of the human hand.
First x ray photo Wilhelm Röntgen
Upon their discovery in 1895, X-rays were advertised as the new scientific wonder and were seized upon by entertainers. Circus patrons could view their own skeletons and were given pictures of their own bony hands wearing silhouetted jewelry. Many people were fascinated by this discovery. Some people, however, feared that it would allow strangers to look through walls and doors and eliminate privacy.HOW X RAYS WORK SHORT VIDEo

Whilst working within close proximity to the radar equipment, he felt a tingling sensation throughout his body and noticed that a chocolate bar in his pocket had completely melted. After some investigation he determined that it was the microwaves being emitted by the magnetron tube in the radar set which had caused the chocolate to get warm enough to melt.

History[edit]
Packet ships (1812–1838)[edit]
The England, a packet ship of the Black Ball Line
The modern era of "liners" was established by the Black Ball Line which began operation in 1818. The packet ships were contracted by governments to carry mail and also carried passengers and timely items such as newspapers. Up till this point there were no regular passages advertised by sailing ships. They arrived at port when they could, dependent on the wind, and left when they were loaded, frequently visiting other ports to complete their cargo
Paddlers
The Sirius is considered the first Blue Riband holder for her 1838 voyage to New York at 8.03 knots (14.87 km/h).
In 1843, Great Western recorded a Blue Riband voyage of 10.03 knots (18.58 km/h).
In 1832, Junius Smith, American lawyer turned London merchant, published the idea of building a line of transatlantic

When the first transatlantic telegraph cable was laid in 1858 by businessman Cyrus West Field, it operated for only three weeks; subsequent attempts in 1865 and 1866 were more successful. Although a telephone cable was discussed starting in the 1920s[citation needed], to be practical it needed a number of technological advances which did not arrive until the 1940s.[citation needed] Starting in 1927, transatlantic telephone service was radio-based.[1]

Scotland Yard said they are treating his death as suspicious and samples of his blood have been sent to the Porton Down Germ Warfare Centre for examination.
Estimates of world population for various points in history have been a subject of study for many years. Many authoritative sources exist for historical population estimates (e.g. U.S. Census estimates of historical world population). This article lists many of these estimates. Estimates previous to the year 10,000 BC can be made only from archaeological evidence.
The last point in which Homo sapiens hit a dangerous low, coming close to extinction, was at approximately 70,000 BC during the Toba catastrophe. The University of Illinois at Urbana-Champaign estimates human world population (Homo sapiens in Africa) between 1,000 and 10,000 breeding couples.[

The Principality of Sealand is a micronation located in the North Sea. Its mass consists of what was HM Fort Roughs, a former Second World War Maunsell Sea Fort, off the coast of Suffolk, England, United Kingdom.[1][9]
While it has been described as the world's smallest country,[10] or the world's smallest nation,[11] Sealand is not recognised by any established sovereign state, although Sealand's government claims it has been de facto recognised by the United Kingdom (after an English court ruled it did not have jurisdiction over Sealand as territorial water limitations were defined at the time)[1] and Germany (see below).
Since 1967 the facility has been occupied by family and associates of Paddy Roy Bates, who claim that it is an independent sovereign state.[1] Bates seized it from a group of pirate radio broadcasters in 1967 with the intention of setting up his own station at the site.[12] He attempted to establish Sealand as a nation-state in 1975 with the writing of a national constitution and establishment of other national symbols.[1] Bates moved to mainland Essex when he became elderly, naming his son Michael regent. Bates died in October 2012 at the age of 91.[13]

The islands consist of Palm Jumeirah, the smallest island, Jebel Ali, and Palm Deira, the largest island. These projects are only possible due to a topographic feature: the shallow, coastal sea in the Persian Gulf reaches far into the open sea, reducing the water depth.

Robert Falcon Scott, CVO (6 June 1868 – c. 29 March 1912) was a Royal Navyofficer and explorer who led two expeditions to the Antarctic regions: theDiscovery Expedition, 1901–04, and the ill-fated Terra Nova Expedition, 1910–13.
Scott, writing his journal in the Cape Evans hut, winter 19112014-06-08
During the research for his dual biography of Scott and Roald Amundsen,[9] polar historian Roland Huntford investigated a possible scandal in Scott's early naval career, related to the period 1889–90 when Scott was a lieutenant on HMS Amphion. According to Huntford, Scott "disappears from naval records" for eight months, from mid-August 1889 until 26 March 1890. Huntford hints at involvement with a married American woman, of cover-up, and protection by senior officers. Biographer David Crane reduces the missing period to eleven weeks,
Popular hero[edit]
Discovery returned to Britain in September 1904. The expedition had caught the public imagination, and Scott became a popular hero. He was awarded a cluster of honours and medals, including many from overseas, and was promoted to the rank of captain.[35] He was invited to Balmoral Castle, where King Edward VII promoted him a Commander of the Royal Victorian Order (CVO).[36]
The expedition had both scientific and exploration objectives; the latter included a long journey south, in the direction of the South Pole. This march, undertaken by Scott,Ernest Shackleton and Edward Wilson, took them to a latitude of 82° 17′ S, about 530 miles (850 km) from the pole. A harrowing return journey brought about Shackleton's physical collapse and his early departure from the expedition
Dispute with Shackleton[edit]
By early 1906, Scott had sounded out the RGS about the possible funding of a future Antarctic expedition.[39] It was therefore unwelcome news to him that Ernest Shackleton had announced his own plans to travel to Discovery's old McMurdo Sound base and launch a bid for the South Pole from there.[40] Scott claimed, in the first of a series of letters to Shackleton, that the area around McMurdo was his own "field of work" to which he had prior rights until he chose to give them up, and that Shackleton should therefore work from an entirely different area.
Scott's group took this photograph of themselves using a string to operate the shutter on 17 January 1912, the day after they discovered Amundsen had reached the pole first.

The Flag of John "Calico Jack" RackhamOpenclipart.orgJohn "Calico Jack" Rackham had a short and largely unimpressive pirate career between 1718 and 1720. Today, he is really only remembered for two reasons. First of all, he had two female pirates on his ship: Anne Bonny and Mary Read. It caused quite a scandal that women could take up pistols and cutlasses and fight and swear their way into full membership on a pirate vessel! The second reason was his very cool pirate flag: a black jack that showed a skull over crossed cutlasses. In spite of the fact that other pirates were more successful, his flag has gained fame as "the" pirate flag.
The Flag of Bartholomew "Black Bart" Roberts, Part OneIf you go by loot alone, Henry Avery was the most successful pirate of his time, but if you go by number of ships captured, then Bartholomew "Black Bart" Roberts beats him by a nautical mile. Black Bart captured some 400 ships in his three-year career, in which he ranged from Brazil to Newfoundland, to the Caribbean and Africa
6. The Flag of Stede Bonnet, "The Gentleman Pirate"Ever notice how some people just seem to wind up in the wrong line of work? During the Golden Age of Piracy, Stede Bonnet was one such man. A wealthy planter from Barbados, Bonnet got sick of his nagging wife. He did the only logical thing: he bought a ship, hired some men and sailed out to become a pirate. The only problem was that he didn't know one end of the ship from the other!

Ann Bonney 1702 1782
While in the Bahamas, Bonny began mingling with pirates in the local taverns. She met Jack "Calico Jack" Rackham, captain of the pirate sloop Revenge, and became his mistress. They had a child in Cuba, who eventually took the name of Cunningham. Many different theories state that he was left with his family or simply abandoned. Bonny rejoined Rackham and continued the pirate life

Satelittes
Satellites operate in extreme temperatures from −150 °C (−238 °F) to 150 °C (300 °F) and may be subject to radiation in space. Satellite components that can be exposed to radiation are shielded with aluminium and other radiation-resistant material
Communication satellites range from microsatellites weighing less than 1 kg (2.2 pounds) to large satellites weighing over 6,500 kg (14,000 pounds). Advances in miniaturization and digitalization have substantially increased the capacity of satellites over the years. Early Bird had just one transponder capable of sending just one TV channel. The Boeing 702 series of satellites, in contrast, can have more than 100 transponders, and with the use of digital compression technology each transponder can have up to 16 channels, providing more than 1,600 TV channels through one satellite.
A signal that is bounced off a GEO satellite takes approximately 0.22 second to travel at the speed of light from Earth to the satellite and back. This delay poses some problems for applications such as voice services and mobile telephony. Therefore, most mobile and voice services usually use LEO
Satellites face competition from other media such as fibre optics, cable, and other land-based delivery systems such as microwaves and even power lines. The main advantage of satellites is that they can distribute signals from one point to many locations. As such, satellite technology is ideal for “point-to-multipoint” communications such as broadcasting. Satellite communication does not require massive investments on the ground
The Intelsat spans theToday there are approximately 150 communication satellites in orbit with over 100 in geosynchronous orbit.
globe, and domestic satellites such as the USSR's Molniya satellites. Western Union's Westar, and Canada's Anik - serve individual countries. The Intelsat V is the latest in its space-craft series, it can handle 12,000 telephone circuits and two color television transmission simultaneously.
Which of the following whirls around the Earth at 5 miles per second? Hubble Space Telescope. The Hubble Space Telescope is named after Edwin Hubble (1889-1953). Hubble's Law (also named after Edwin Hubble) is a theory that suggests that there is a constantly expanding universe.
Weather Satellites
The first weather satellite was launched on February 17, 1959. What was the name of this satellite? Vanguard 2. Vanguard 2 was designed to measure cloud cover, however, this satellite was poor in collecting data as a poor axis and rotation kept it from collecting meaningful information. TIROS-1 which was launched by NASA in 1960, was the first successful weather satellite and operated for 78 days.
THE MOON
The prevailing hypothesis today is that the Earth–Moon system formed as a result of agiant impact, where a Mars-sized body (named Theia) collided with the newly formed proto-Earth, blasting material into orbit around it that accreted to form the Moon.[20] This hypothesis perhaps best explains the evidence, although not perfectly.
The Moon is drifting away from the Earth:The Moon is moving approximately 3.8 cm away from our planet every year. It is estimated that it will continue to do so for around 50 billion years. By the time that happens, the Moon will be taking around 47 days to orbit the Earth instead of the current 27.3 days.
