Albert Einstein



Albert Einstein   (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). While best known for his mass energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"), he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory.
Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.
In 1901, his paper "Folgerungen aus den Capillaritatserscheinungen" ("Conclusions from the Capillarity Phenomena") was published in the prestigious Annalen der Physik. On 30 April 1905, Einstein completed his thesis, with Alfred Kleiner, Professor of Experimental Physics, serving as pro-forma advisor. Einstein was awarded a PhD by the University of Zurich. His dissertation was entitled "A New Determination of Molecular Dimensions". That same year, which has been called Einstein's annus mirabilis (miracle year), he published four groundbreaking papers, on the photoelectric effect, Brownian motion, special relativity, and the equivalence of mass and energy, which were to bring him to the notice of the academic world.
By 1908, he was recognized as a leading scientist, and he was appointed lecturer at the University of Bern. The following year, he quit the patent office and the lectureship to take the position of physics docent at the University of Zurich. He became a full professor at Karl-Ferdinand University in Prague in 1911. In 1914, he returned to Germany after being appointed director of the Kaiser Wilhelm Institute for Physics (1914–1932) and a professor at the Humboldt University of Berlin, with a special clause in his contract that freed him from most teaching obligations. He became a member of the Prussian Academy of Sciences. In 1916, Einstein was appointed president of the German Physical Society (1916–1918).
During 1911, he had calculated that, based on his new theory of general relativity, light from another star would be bent by the Sun's gravity. That prediction was claimed confirmed by observations made by a British expedition led by Sir Arthur Eddington during the solar eclipse of 29 May 1919. International media reports of this made Einstein world famous. On 7 November 1919, the leading British newspaper The Times printed a banner headline that read: "Revolution in Science – New Theory of the Universe – Newtonian Ideas Overthrown". Much later, questions were raised whether the measurements had been accurate enough to support Einstein's theory. In 1980 historians John Earman and Clark Glymour published an analysis suggesting that Eddington had suppressed unfavorable results. The two reviewers found possible flaws in Eddington's selection of data, but their doubts, although widely quoted and, indeed, now with a "mythical" status almost equivalent to the status of the original observations, have not been confirmed. Eddington's selection from the data seems valid and his team indeed made astronomical measurements verifying the theory.
In 1921, Einstein was awarded the Nobel Prize in Physics for his explanation of the photoelectric effect, as relativity was considered still somewhat controversial. He also received the Copley Medal from the Royal Society in 1925.

H.H Holmes



The story starts in Chicago, in the 1800’s. Chicago has been selected to host the world fair, but the fair won’t only will be fun it will be deadly. H.H.Holmes arrived for the fair, He stops by a local pharmacy, later the owner will disappear and Holmes will convince his wife to sell him the store.  Later she will disappear. No one will suspect a thing.
 In the newspaper Holmes posts that he needs an assistant, a young woman takes the job, Holmes convinces her to marry him. While the city of Chicago is building the fairgrounds and the white city Holmes has his own plans to build a hotel. Once he finished his hotel he managed to get his wife into one of his specially designed rooms it’s a tiny room with no vents or windows, in another room he designed he can turn on natural gases from a secret room in his office. Sometimes he stops and listens to her fighting for her life.
 Further along the story he meets another nice women and her sister nanny, He convinces the lady to marry him but there’s one person in the way nanny, he has nanny working for him he asks her to get him his documents from the vault while she steps inside it he locks her in then turns the gas on in her sisters room leaving them both to die.
His business is done in Chicago next he heads to Philadelphia, where he will scam people of their money with a fake credit company. People start noticing Holmes has made his first mistake he is sent to jail where he makes peace with his guards.  He likes to write in jail him and his guards also exchange stories.
While in Chicago people are wondering how people go to the fair and just disappear they expect Holmes had to do with the disappearing’s of everyone. So the police search his hotel, they cannot believe what they find they discover his secret autopsy room in the basement and hidden passages so he can kill his guests. Holmes is proven guilty. Later he is sentenced to be hanged just eight days before his thirty-eighth birthday.He will always remember the fair and the white city.

Dodo Birds



The Dodo (Raphus cucullatus) is an extinct flightless bird that was endemic to the island of Mauritius, east of Madagascar in the Indian Ocean. Its closest genetic relative was the also extinct Rodrigues Solitaire, the two forming the subfamily Raphinae of the family of pigeons and doves. The closest living relative of the Dodo is the Nicobar Pigeon. A white Dodo was once incorrectly thought to have existed on the nearby island of Reunion.
The Dodo's external appearance is evidenced only by paintings and written accounts from the 17th century. Because these vary considerably, and because only a few sketches are known to have been drawn from live specimens, its exact appearance in life remains a mystery. Similarly, little is known with certainty about its habitat and behaviour. Subfossil remains show the Dodo was about one metre (3.3 ft) tall and may have weighed 10–18 kg (22–40 lb) in the wild. It has been depicted with brownish-grey plumage, yellow feet, a tuft of tail feathers, a grey, naked head, and a black, yellow, and green beak. It used gizzard stones to help digest its food, which is thought to have included fruits, and its main habitat is believed to have been the woods in the drier coastal areas of Mauritius. One account states its clutch consisted of a single egg. It is presumed that the Dodo became flightless because of the ready availability of abundant food sources and a relative absence of predators on Mauritius.
The first recorded mention of the Dodo was by Dutch sailors in 1598. In the following years, the bird was preyed upon by hungry sailors, their domesticated animals, and invasive species introduced during that time. The last widely accepted sighting of a Dodo was in 1662. Its extinction was not immediately noticed, and some considered it to be a mythical creature. In the 19th century, research was conducted on a small quantity of remains of four specimens that had been brought to Europe in the early 17th century. Since then, a large amount of subfossil material has been collected from Mauritius, mostly from the Mare aux Songes swamp. The extinction of the Dodo within only about a century of its discovery called attention to the previously unrecognised problem of human involvement in the disappearance of entire species. The Dodo achieved widespread recognition from its role in the story of Alice in Wonderland, and it has since become a fixture in popular culture, often as a symbol of extinction and obsolescence. It is frequently used as a mascot on Mauritius.

Slonvenia



Present-day Slovenia was long inhabited in prehistoric times, and there is evidence of human habitation around 250,000 years ago. A pierced cave bear bone, dating from 43100 - 700 BP, found in 1995 in Divje Babe cave near Cerkno, is possibly the oldest musical instrument discovered in the world. In 1920s and 1930s, artifacts belonging to the Cro-Magnon such as pierced bones, bone points, and needle have been found by archeologist Srecko Brodar in Potok Cave. In 2002, more than 4,500 years old remains of pile dwellings were discovered in the Ljubljana Marshes, now protected as a UNESCO World Heritage Site, along with the Ljubljana Marshes Wooden Wheel, the oldest wooden wheel in the world. It shows that wooden wheels appeared almost simultaneously in Mesopotamia and Europe. In the transition period between the Bronze age to the Iron age, the Urnfield culture flourished. Archeological remains dating from the Hallstatt period have been found, particularly in southeastern Slovenia, among them a number of situlas in Novo Mesto, the "Town of Situlas". In the Iron Age, present-day Slovenia was inhabited by Illyrian and Celtic tribes until the 1st century BC.
Ancient Romans
When the Ancient Romans conquered the area, they established the provinces of Pannonia and Noricum and present-day western Slovenia was included directly under Roman Italia as part of the X region Venetia et Histria. The Romans established posts at Emona (Ljubljana), Poetovio (Ptuj) and Celeia (Celje), and constructed trade and military roads that ran across Slovene territory from Italy to Pannonia. In the 5th and 6th centuries, the area was subject to invasions by the Huns and Germanic tribes during their incursions into Italy.
Slavic settlement
The Slavic tribes migrated to the Alpine area after the departure of the Lombards (the last Germanic tribe) westwards in 568, and with aid from Avars established Slavic settlement of the Eastern Alps. The King Samo united the Alpine, Western, and Northern Slavs against the nomadic Eurasian Avars who ruled from 623 to 626 and established what is referred to as the Samo's Kingdom. After its disintegration in 658, the ancestors of Slovenes located in present-day Carinthia formed the independent duchy of Carantania. Other parts of present-day Slovenia were again ruled by Avars before Charlemagne's victory over them in 803.
In the mid-8th century, Carantania became a vassal duchy under the rule of the Bavarians, who began spreading Christianity. Three decades later, the Carantanians were incorporated, together with the Bavarians, into the Carolingian Empire. During the same period Carniola, too, came under the Franks, and was Christianized from Aquileia. Following the anti-Frankish rebellion of Ljudevit Posavski at the beginning of the 9th century, the Franks removed the Carantanian princes, replacing them with their own border dukes. Consequently, the Frankish feudal system reached the Slovene territory.
The Magyar invasion of the Pannonian Plain in the late 9th century effectively isolated the Slovene-inhabited territory from western Slavs. Thus, the Slavs of Carantania and of Carniola began developing into an independent Slovene ethnic group. After the victory of Emperor Otto I over the Magyars in 955, Slovene territory was divided into a number of border regions of the Holy Roman Empire. Carantania, being the most important, was elevated into the Duchy of Carinthia in 976. In the late Middle Ages, the historic provinces of Carniola, Styria, Carinthia, Gorizia, Trieste and Istria developed from the border regions and incorporated into the medieval German state. The consolidation and formation of these historical lands took place in a long period between the 11th and 14th centuries, being led by a number of important feudal families, such as the Dukes of Spannheim, the Counts of Gorizia, the Counts of Celje and finally the House of Habsburg. In a parallel process, an intensive German colonization significantly diminished the extent of Slovene-speaking areas; by the 15th century, the Slovene ethnic territory was reduced to its present size.
In the 14th century, most of the territory of Slovenia was taken over by the Habsburgs. The counts of Celje, a feudal family from this area who in 1436 acquired the title of state princes, were their powerful competitors for some time. This large dynasty, important at a European political level, had its seat in Slovene territory but died out in 1456. Its numerous large estates subsequently became the property of the Habsburgs, who retained control of the area right up until the beginning of the 20th century.

Meriam Makeba



Miriam Makeba (4 March 1932 – 9 November 2008), nicknamed Mama Africa, was a Grammy Award-winning South African singer and civil rights activist.
In the 1960s she was the first artist from Africa to popularize African music in the U.S. and around the world. She is best known for the song "Pata Pata", first recorded in 1957 and released in the U.S. in 1967. She recorded and toured with many popular artists, such as Harry Belafonte, Paul Simon, and her former husband Hugh Masekela.
Makeba campaigned against the South African system of apartheid. The South African government responded by revoking her passport in 1960 and her citizenship and right of return in 1963. As the apartheid system crumbled she returned home for the first time in 1990.
Makeba died of a heart attack on 9 November 2008 after performing in a concert in Italy organized to support writer Roberto Saviano in his stand against the Camorra, a mafia-like organisation local to the region of Campania.
On 4 March 2013 - what would have been her 81st birthday Google commemorated her life with a "doodle".
Zenzile Miriam Makeba was born in Johannesburg on 4 March 1932. Her mother was a Swazi sangoma (traditional healer-herbalist). Her father, who died when she was six years old, was a Xhosa. When she was eighteen days old, her mother was arrested for selling umqombothi, an African homemade beer brewed from malt and cornmeal. Her mother was sentenced to a six-month prison term, so Miriam spent her first six months of life in jail. As a child, she sang in the choir of the Kilmerton Training Institute in Pretoria, a primary school that she attended for eight years.
In 1950 at the age of eighteen, Makeba gave birth to her only child, Bongi Makeba, whose father was Makeba's first husband James Kubay. Makeba was then diagnosed with breast cancer, and her husband left her shortly afterwards.
Her professional career began in the 1950s when she was featured in the South African jazz group the Manhattan Brothers, and appeared for the first time on a poster. She left the Manhattan Brothers to record with her all-woman group, The Skylarks, singing a blend of jazz and traditional melodies of South Africa. As early as 1956, she released the single "Pata Pata", which was played on all the radio stations and made her name known throughout South Africa.
She had a short-lived marriage in 1959 to Sonny Pillay, a South African singer of Indian descent. Her break came in that year when she had a short guest appearance in Come Back, Africa, an anti-apartheid documentary produced and directed by American independent filmmaker Lionel Rogosin. The short cameo made an enormous impression on the viewers and Rogosin managed to organise a visa for her to attend the première of the film at the twenty-fourth Venice Film Festival in Italy, where the film won the prestigious Critics' Award. That year, Makeba sang the lead female role in the Broadway-inspired South African musical King Kong; among those in the cast was musician Hugh Masekela. She made her U.S. debut on 1 November 1959 on The Steve Allen Show.
