Biography of Albert Einstein
Albert Einstein was born at Ulm, in Württemberg, Germany, 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 acquired 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 at the Patent 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 renounced his citizenship for political reasons and emigrated to America to take the position of Professor of Theoretical Physics at Princeton. He became a United States citizen in 1940 and retired from his post in 1945.
After World War II, Einstein 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 Weizmann in establishing the Hebrew University of Jerusalem.
Einstein always appeared to 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 reconcile the laws of mechanics with the laws of the electromagnetic field. He dealt with classical problems of statistical mechanics and problems in 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 observations laid the foundation 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 problems of the theory of radiation and statistical mechanics.
In the 1920"s, Einstein embarked on the construction 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 mechanics by his development of the quantum theory of a monatomic gas and he has also accomplished valuable work in connection with atomic transition probabilities and relativistic cosmology.
After his retirement he continued to work towards the unification of the basic concepts of physics, taking the opposite approach, geometrisation, to the majority of physicists.
Einstein"s researches are, of course, well chronicled and his more important works include Special Theory of Relativity (1905), Relativity (English translations, 1920 and 1950), General Theory of Relativity (1916), Investigations on Theory of Brownian Movement (1926), and The Evolution of Physics (1938). Among his non-scientific works, About Zionism (1930), Why War? (1933), My Philosophy (1934), and Out of My Later Years (1950) are perhaps the most important.
Albert Einstein received honorary doctorate degrees in science, medicine and philosophy from many European and American universities. During the 1920"s he lectured in Europe, America and the Far East and he was awarded Fellowships or Memberships of all the leading scientific academies throughout the world. He gained numerous awards in recognition of his work, including 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 intellectual solitude and for relaxation music played an important part in his life. He married Mileva Maric in 1903 and they had a daughter and two sons; their marriage was dissolved in 1919 and in the same year he married his cousin, Elsa Löwenthal, who died in 1936. He died on April 18, 1955 at Princeton, New Jersey.

This autobiography/biography was first published in the book series Les Prix Nobel. It was later edited and republished in Nobel Lectures.

 Biography of Mahmood Hesabi
"Professor Mahmood Hesabi was born in Tehran in 1903 (1281, A.H. Solar). His parents were from Tafresh. At the age of four his family moved to Syria and at the age of seven he moved to Beirut and while tolerating difficult situations and poverty he started his education at elementary school far from the home land in a French Priests" School. At the same time, his mother, Gohar Shad Hesabi, who was dedicated, religious and knowledgeable woman, started teaching him Persian Literature and religious education.


Hesabi memorized Quran and he had very strong belief in it. He also memorized Hafez"s Diwan and had completed proficiency in Saadi"s Bustan and Golestan, Ferdowsi"s Shahname, Molavi"s (Rumi"s) Masnavi and Ghaem Magham"s Monshaat.


The beginning of his guidance school coincided with the start of the World War I when the French schools of Beirut were closed. After two years of studying at home he prosecuted his studies at American University of Beirut and obtained his BA in Literature at the age of 17, and at the age of 19 he got his BA in Biology. Then he obtained a degree in engineering and earned money as a draftsman and a civil engineer. Hesabi also studied Medicine, Mathematics and Astrology.


In order to appreciate Hesabi, the civil engineering company that he was working there dispatched him to France for prosecution of studies. He was admitted to the "Ecole Superieure d"Electricite" in 1924 and graduated in 1925. Concurrent with studying mineralogy he was hired by the French Electric Railway Co. and after graduation in this field he started his work in Iron mines of north of France and Coal mines of the state of "Sar".


Since he had a scientific mind and spirit he continued his studies and research in Physics at Sorbonne University. He obtained his PhD IN Physics with an excellent degree at the age of 25. The title of his dissertation was "Sensitivity of Photo Electric Cells".

At that time when 15 thousand people were volunteers to attend Einstein"s class he had the chance to be one of the 5 chosen ones. He had a meeting with Einstein at Princeton in American and one year later he presented a theory called "Infinitely Extended Particles". By the help and guide of Einstein and his own research in Chicago University he was able to defend his theory and explain it to other great scientists such as Born, Mezmi and Schrodinger and he was awarded the medal of the "Commandeur De La Legion D"honneure", France"s greatest scientific medal. When he returned to Princeton, Einstein elected him as a substitute of himself at this university and it was a very big honor that he received.


The following are some of his accomplishments in scientific fields:


Founding modern sciences, founding "Teachers" College" (Dar-ul Moallemin), construction of the first radio-set in Iran, founding higher college for teachers and teaching Physics and Mechanics there, construction of the first weather-station, installation and operation of the first radiology center (for his brother Dr. Mohammad Hesabi), establishing Persian Language Academy, Topography, founding Tehran-Shemshak Railway, founding Tehran University and acting as the dean and the instructor of the university, founding applied optic and lens-making center at Tehran University, establishing the first modern observatory in Iran, establishing nomad school in the country, establishing Geophysics Society of Iran, founding the atomic research Center and Atomic Reactor of Tehran University, founding modern center for satellite studies in Shiraz, founding Physics Society of Iran and etc.


While serving the country during this period he continued his scientific cooperation such as membership of Oslo Mathematics Congress in Norway, membership of Princeton scientific conference, membership of research team at Institute of Nuclear Research of Chicago, membership of New York Science Academy, membership of Geneva Atomic Conference, membership of Physics Society of Europe and America, etc.


He spoke five living languages Persian, French, English, German and Arabic and he also knew Sanskrit, Latin, Greek, Pahlavi, Avestan, Turkish and Italian which he used for his etymological studies.


He was chosen as the Man of Science in the World in 1989. On 3rd of September, 1992 (12th of Shahrivar 1371, A.H. Solar) at 7:30 am (still a university professor at Tehran University) he passed away in hospital of Geneva University after a period of illness."

By the way, "Professor Hesabi was the only Iranian student of Professor Albert Einstein and was known to be his favorite student. During his years of scientific research he met many distinguished scientists such as Erwin Schrodinger, Max Born, Enrico Fermi, Paul Dirac, and Aage Niels Bohr and scholars such as Bertrand Russell and Andre Gide."

Biography of

Helen Keller

  • Born: 27 June 1880
  • Birthplace: Tuscumbia, Alabama
  • Died: 1 June 1968 (natural causes)
  • Best Known As: The blind and deaf woman who became a famous activist

Helen Keller was, for a time, the most famous handicapped person in the world. A severe fever at age 19 months left Keller blind and deaf and barely able to communicate. At age six Keller met Anne Sullivan (later Anne Sullivan Macy), the tutor who taught Keller the alphabet and thereby opened up the world to her. Keller became an excellent student and eventually attended Radcliff College, where she graduated with honors in 1904. While at Radcliff she wrote an autobiography, The Story of My Life (1902), which made her famous. Her many later books included The World I Live In (1908), Out of the Dark (1913), and 1938s Helen Kellers Journal. In later life Keller became an activist and lecturer, sometimes in support of the blind and deaf, and sometimes for causes including Socialism and womens rights. She also founded and promoted the American Foundation for the Blind. During her lifetime Keller was regarded as one of Americas most inspirational figures.

Kellers story was told in a 1957 television play, The Miracle Worker, which later became a Broadway play (1959) and then a 1962 film starring Anne Bancroft as Sullivan and Patty Duke as Keller; both Bancroft and Duke won Academy Awards for their work... Kellers image appears on the quarter-dollar coin honoring Alabama, first released in 2003. According to the U.S. Mint, the coin is the first U.S. coin to feature Braille.

Who was Einstein?Einstein was the world’s most popular physic scientist of 20 century. He was a physic tutor and his wife was a mathematic tutor and she has such a mathematic talent and power that Einstein has said that she was my tutor in some fields. They had worked together and designed lots of valuable formulas and theories. Einstein has two best popular, valuable and reasonable theories are: 1: Quantum theory: The quantum theory that says the energy transfer from one thing to another thing by something like boxes that have very light mass.2: The filament theory: The filament theory that could elaborates and expounds all aspects of the earth, materials, energies and at all it could describes all world and it’s events.In the following there is a description about Einstein has adopted from an electrical dictionary’s entry:Physicist born in Germany who formulated the special theory of relativity and the general theory of relativity; Einstein also proposed that light consists of discrete quantized bundles of energy (later called photons) (1879-1955).Question: It is what I want to ask you: What are details about quantum’s and filament’s theories? Like always correct me please!!!!!!!!!!!!!!!!!!!!!!!!ThaNk yOu alL sO MucH

Hans Christian Oersted

Born: 14-Aug-1777
Birthplace: Rudkøbing, Denmark
Died: 9-Mar-1851
Location of death: Copenhagen, Denmark
Cause of death: unspecified

Gender: Male
Race or Ethnicity: White
Occupation: Physicist, Chemist

Nationality: Denmark
Executive summary: Discovered electromagnetics

One of the most distinguished scientific discoverers and physicists of his time, Oersted was born in 1777 at Rudkjobing, on the Danish island of Lange land, where his father practiced as an apothecary. In 1794, he entered the University of Copenhagen, where he took the degree of doctor of philosophy in 1799, and soon afterwards became assistant to the professor of medicine, in which capacity he gave lectures on chemistry and natural philosophy. In 1806, after having enjoyed a traveling scholarship for several years, and visited Holland, the greater part of Germany, and Paris, he was appointed extraordinary professor of natural philosophy in the University of Copenhagen.

During his residence at Berlin, he wrote his famous essay on the identity of chemical and electrical forces, in which he first developed the ideas on which were based his great discovery of the intimate connection existing between magnetism and electricity and galvanism -- a treatise which, during his residence in Paris, he translated into French, in conjuction with Marcel de Serres. In 1819, he made known these important truths in a Latin essay, entitled Experimenta circa Efficaciam Conflictus Electrici in acum Magneticam, which he addressed to all the scientific societies and th eleading savans of Europe and America, and thus made good his claim to be regarded as the originator of the new science of electromagnetism. This discovery, which formed one of the most important eras in the history of physical science, obtained for Oersted the Copley Medal from the Royal Society of England, and the principal mathematical prize in the gift of the Institute of Paris. The original and leading idea of this great discovery had been in his mind since 1800, when the discovery of the galvanic battery by Alessandro Volta had first led him to enter upon a course of experiments on the production of galvanic electricity. The enunciation of his theory of electromagnetism was followed by many important experiments in regard to the compression of water, and by numerous other chemical discoveries, among which we may instance his demonstration of the existence of the metal aluminum in alumina.

The influence which Oersted exerted on the science of the day by his discoveries was recognized by the learned in every country, and honors increased upon him with increasing years. Oersted’s great object through life was to make science popular among all classes, in furtherance of which he wrote numerous works, contributed scientific papers to the newspapers and magazines of his own country and Germany, and in addition to his regular prelections in the university, gave courses of popular scientific lectures to the public, including ladies. The majority of his more important physical and chemical papers are contained in Poggendorff"s Annalen, and were written by him in German or French, both of which he wrote with the same faculty as his own language. At the close of 1850, a national jubilee was held in honor of the 50th anniversary of his connection with the University of Copenhagen -- a festival which he did not long survive, as his death occurred at Copenhagen on 9th March 1851. A public funeral, attended by all persons distinguished by rank or learning in the Danish capital, bore testimony to the respect and esteem with which he was regarded by his fellow citizens, among whom his memory is cherished, not merely as one of the greatest scientific benefactors of his times, but as a man who contributed largely, by his eloquent and earnest advocacy of liberal principles, to the attainment of the high degree of constitutional freedom which Denmark now enjoys.
