Albert Einstein (biography)

Abert Einstein was born at Ulm, in Wurttemberg, Germay, on March 14, 1879. Six weeks later the family moved to Munich, where he later on began his schooling at the Luitpold Gymnasium. Later, they moved to Italy and Albert continued his education at Aarau, Switzerland and in 1896 he entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. In 1901, the year he gained his diploma, he acqured Swiss citizenship and, as he was unable to find a teaching post, he accepted a position as technical assistant in the Swiss Patent Office. In 1905 he obtained his doctor's degree.

During his stay atthe Patene Office, and in his spare time, he produced much of his remarkable work and in 1908 he was appointed Privatdozent in Berne. In 1909 he became Professor Extraordinary at Zurich, in 1911 Professor of Theoretical Physics at Prague, returning to Zurich in the following year to fill a similar post. In 1914 he was appointed Director of the Kaiser Wilhelm Physical Institute and Professor in the University of Berlin. He became a German citizen in 1914 and remained in Berlin until 1933 when he renouced his citizenship for political reasons and emigrated to America to take the position of Professor of Theoretical Physics at Princton*. He became a United States citizen in 1940 and retired from his post in 1945.

After World War II, Enstein was a leading figure in the World Government Movement, he was offered the Presidency of the State of Israel, which he declined, and he collaborated with Dr. Chaim Wezmann in establishing the Hebrew University of Jerusalem.

Einstein always appearedto have a clear view of the problems of physics and the determination to solve them. He had a strategy of his own and was able to visualize the main stages on the way to his goal. He regarded his major achievements as mere stepping-stones for the next advance.

At the start of his scientific work, Einstein realized the inadequacies of Newtonian mechanics and his special theory of relativity stemmed from an attempt to recencle the laws of mechanics with the laws of the electromagnetic field. He dealt with classical problems of statistical mechanics and problems is which they were merged with quantum theory: this led to an explanation of the Brownian movement of molecules. He investigated the thermal properties of light with a low radiation density and his obsevations laid the fondation of the photon theory of light.

In his early days in Berlin, Einstein postulated that the correct interpretation of the special theory of relativity must also furnish a theory of gravitation and in 1916 he published his paper on the general theory of relativity. During this time he also contributed to the promlems of the theory of radiation and statistical mechanics.

In the 1920's, Einstein embarked on the constuction of unified field theories, although he continued to work on the probabilistic interpretation of quantum theory, and he persevered with this work in America. He contributed to statistical emchacis by his devopment of the quantum theory of a monatomic gas and he has also acccomplished valuable work in dennection with atomic transition pro babilities and relativistic cosmology.

After his retirement he continued to wourk towards the unification of the basic concepts of physics, taking the opposite approach, gemetrisation, to the majority of physicsts.

Albert Einstein received honorary doctorate degrees in scince, medicine and philosophy from Europen and American universities. During the 1920's he lectured in Europe, America and the Far East and he was awrded Fellowships or work, in cluding the Copley Medal of the Royal Society of London in 1925, and the Franklin Medal of the Franklin Institute in 1935.

Einstein's gifts inevitably resulted in his dwelling much in inteectula solitude and , for relaxition, music played an importanat part in his life. He married Mileva Maric in 1903 and they had daugther and two sons; their marriage was dissolved in 1919 and in the same year he marriedhi cousin, Elsa Lowenthal, who died in 1936. He died on April 18, 1955 at Princeton, New Jersey.

Halloween falls on October 31th each year in North America and other parts of the worid. What do you know about Halloween? Do you celebrate it in your country? Here is a little history about it.

Like many other holidays, Halloween has evolved and changed throughout history. Over 2,000 years ago people called the Celts lived in what is now Ireland, the UK, and parts of Nor them France. November 1 was their New Year's Day. They believed that the night before the Ne Year (October 31) was a time when the living and the dead came together.

More than a thousand years ago the Christian church named November 1 All Saints Day (also called All Hallows). This was a special holy day to honor the saints and other people who died for their religion. The night before All Hallows was called Hallows Eve. Later the name was changed to Halloween.

Like the Celts, the Europeans of that time also believed that the spirits of the dead would visit the earth of Hallowen. They worried that evil spirits would cause problems or hurt them. So on that night people wore costumes that looked like ghosts or other evil creatures. They thought if they dressed like that, the spirits would think they were also dead and not harm them.

The tradition of Halloween was carried to America by the immigrating Europeans. Some of the traditions changed a little, though. For example, on Halloween if Europe some people would carry lanterns made from turnips. In America, pumkins were more comon. So people began putting candies inside the and using them as lanterns. That is why you see Jack `o lanterns today.

These days Halloween is not usually considered a religious holiday. It is primarily a fun day for children. Children dress up in costumes like people did a thousand years ago. But instead of worrying about evil spirits, they go from house. They knock on doors and say "trick or treat". They owner of each house gives candy or something special to each trick or treater.
