Motor Car

Daimler, Maybach and Benz introduce the first practical gasoline-engine automobile.

It is difficult, if not impossible, to imagine a world without the motorcar. When German engineer Karl Benz ( 1844-1929 ) drove a motorcar tricycle in 1885 and

 Wilhelm Maybach (1846-1929) converted a horse-drawn carrige into a four-wheeled motorcar in August 1886,

none of them could have foreseen the effects of their new invention.

Benz recognized the great potential of petrol as a fuel. His three-wheeled car had a top speed of just ten miles (16 km) per hour with its four-stroke, one cylinder engine. After receiving his patent in January 1886, he began selling the Benz Velo, but the public doubted it's reliability.

Benz's wife Bertha had a brilliant idea to advertise the new car. In 1888 she took it on a 60-mile (100 km) trip from Mannheim to near Stuttgart. Despite having to push the car up hills, the success of the journey proved to a skeptical public that this was a reliable mode of transport.

Daimler and Maybach did not produce commercially feasible cars until 1889. Initially the German inventions did not meet with much demand, and it was French companies like Panhard et Levassor that redesigned and popularized the automobile.

 In 1926 Benz's company merged to form the Daimler-Benz company. Benz had left his company in 1906 and, remarkably, he and Daimler never met. Due to higher incomes and cheaper, mass-produced cars, the United States led in terms of motorization for much of the twentieth century.

This kind of movement has, however, come at a cost. Some 25 million people are estimated to have died in car accidents worldwide during the twentieth century. Climate-changing exhaust gases and suburban sprawl are but two more of the consequences of a heavy reliance on the automobile...

The Greek Civilization

The earliest Greek civilization thrived nearly 4,000 years ago. The Ancient Greeks lived in Greece and the countries that we now call Bulgaria and Turkey. The Greek Empire was most powerful between 2000 BC and 146 BC.

Ancient Greece was split into many different states: each state had its own laws, government and money but they shared the same language and religion. The two most important city states were states were Athens and Sparta.

The Greeks focused more on the mind instead of the gods.

They developed new ideas for government, science, philosophy, religion, and art. Their influence is still felt by us today.

The word “ democracy ” is Greek; it means “ government by the people ”. The word ‘ theatre ’ is Greek; most modern theatres follow the Greek plan.“ Polis ”, the Greek word for “ city state ” is where the word “ Politics ” came from. The first Olympic Games were held in 776 BC at the Greek city of Olympia.

The Ancient Greeks played an important part in the development of the alphabet. The first two letters of the Greek alphabet - alpha and beta - have given us the word “ alphabet ”...

The Egyptian Civilization

Ancient Egypt was an ancient civilization of eastern North Africa and it developed around the river Nile. Egypt was an agricultural state. The Egyptian turned desert patches into farmlands, irritating them with the Nile's water. The yearly flooding of the Nile enriched the soil and brought good harvests and wealth to the land. The people of ancient Egypt built mudbrick homes in villages and in country.

The main Egyptian god was Amon Re, the king of all gods. One important Egyptian symbol was that of the solar disk surrounded by the sacred snake. Crocodiles were sacred in the ancient Egypt, and they were even embalmed. Ibis was the sacred bird.

Egyptians used hiéroglyphic inscriptions - a writing system using picture symbols or diagrams. These diagrams were thought to have magical powers.
             Hieroglyphic Inscriptions

 To preserve the magical power of their art. the Egyptians believed they must copy exactly the style handed down through the ages. This meant that most artists painted in the same way, and the people they painted all looked the same.

The Egyptians loved music and played instruments like the harp. They loved beauty and fashion; eye paint was worn both by men and women. They also used a lot of perfume and jewellery .

The Egyptian people believed that their rulers, or pharaohs, were gods, and that they would continue to work even after their death. So, they preserved the bodies of the kings through the process of mummification. Mummies were entombed and included food, gifts and provisions were kept there for the afterlife.
                 The Pyramid Of Giza 

The pyramids were built to contain the tombs of pharaohs To avoid the theft of the treasures and tomb's profanation, the architects built a real labyrinth of false passages inside the pyramid, to confuse the thieves. The pyramids were the earliest buildings ever to be made by precisely cutting and putting together great blocks of stone. One of the most famous pyramids is the Great Pyramid of Khufu. It has 2,300,000 blocks and each block in the pyramid weighs 2.5tons.
                      Mummification 

The civilization coalesced around 3150 BC and lasted for three millennia until the conquest of Alexander the Great...

What is Space?

Space holds many secrets. It contains places  where human beings can be stretched into spaghetti shapes, or boiled, or frozen solid: that's  why astronauts wear protective clothing in the  space. 

Welcome to a mysterious — and endlessly fascinating — world. 

What is space?
                               When people think of space,  they think of:
                      Weightlessness — everything  floats as if there's no gravity.
                       Nothingness — vast areas of  space are completely empty.
                        Stars —  every star is a burning ball of gas. Our Sun is a star.
                         ♠  Astronautspeople who  explore the world beyond our Earth.
                          Rockets and Satellites — These  are what scientists use to explore space.
                           Silence — there is no air in  space, so there is absolutely no sound.

 


Is that space?
                              On a cloudless night, you can see  thousands of stars. Space is the name we give to  the huge empty areas in between the  atmospheres of stars and planets. Apart from the odd rock, space is sprinkled only with dust and  gas.

Why is space so dark?
                                            Space is black because  there is nothing there to reflect light. From space,  Earth looks lit up because light from our Sun  reflects off sea, and land, and the particles in our  atmosphere.

How the distance is measure in space?
                                                                         The  distance measure in space in light years. One light year is the distance light travels in one year: that's  10 million million km ( 6 million million miles ). 

Is anyone there?
                                  • If there are aliens, it is unlikely they will speak the languages of Earth, so  communication may be a problem. Coded signals  have been sent into space. People are also  listening for signals from space.
           
                                   SETI ( The search for Extra Terrestrial Intelligence ) uses powerful radio  telescopes to scan for alien signals. However, so  far nothing has been found. 
         
                                   Message into space:
                                                                         In 1974,
 astronomers at Arecibo, Puerto Rico, sent a radio  message from us to the stars. It was sent towards 
a cluster of stars called M13, where it will arrive  in 25,000 years. We may then get a reply after  another 25,000 years.( Is anyone there to read it ! )
                                    
 The Arecibo message lasts  three minutes. It is consists of 1,679 pulses,  which when arranged from a pictogram. The  pictogram explains the basis of life.

 Is a black hole may be a doorway to another  universe?
                 Some people think a black hole may be a doorway to another universe. But it's all just  speculation. Nobody really knows. However, it is  doubtful someone could survive the journey  through the hole to find out. An astronaut unfortunate enough to try would be stretched out  like a piece of spaghetti...

History of France 🇫🇷 ( From Brest To Strasbourg )

The history of France dates back thousands of  years ago when the earliest human being arrived in the area. In ancient times, France was part of the Celtic territory known as Gaul or Gallia. Later,  Gaul was subject to barbarian raids by the  Germanic Franks.

                 The Frankish King Clovis I.

 In the late 5th century, the  Frankish king Clovis I united most of Gaul under  his rule , setting the stage for Frankish dominance  in the region for hundreds of years. France  became separate country in the 9th century. 

              French Before The Revolution.

The French society was divided into three separate castes known as estates. The first  estate was made up of priests, and reglious  leaders. The second estate was made up of the  nobility, while third and lowest estate consisted of  everyone else, over 97% of the population of  France.  

In time, most of the western part of France was yielded to the British crown. After the death of the  last Capetian King Charles IV, Edward III of  England claimed the French Throne and started  the Hundred Years' War in 1337.

 With the help of  a France peasant girl, Joan of Arc, Charles VIII  emerged victorious in the war and drove the  English back to Calais
    Right - Joan of Arc ; Left - Charles III of France.

France became a centralized state where an absolute monarchy was established. The long  Italian Wars ( 1494—1559 )marked the beginning  of early modern France.

France has six overseas departments: French  Guiana in South America; Guadeloupe and  Martinique in the West Indies; Mayotte, an island  formerly part of the Comoros, located in the  Indian Ocean; Reunion, an island in the Indian  Ocean; and Saint Pierre and Miquelon, islands off  the east coast of Canada. In addition, it has  numerous small possessions called overseas  territories and many small islands in the southern  oceans.

Since the 17th century, France has played a major  role in European and world events. In the 20th  century, it has experienced numerous crises, and  the loss of a large empire in Indochina, Algeria,  and West and Equatorial Africa. It has, however,  survived and emerged as an important world  supplier of agricultural and industrial products.  France has been a leading member in the United  Nations, the European Union and NATO, and  remains a strong economic, cultural, and political 
influence in 21st century...
