• 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 1938’s Helen Keller’s 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 women’s rights. She also founded and promoted the American Foundation for the Blind. During her lifetime Keller was regarded as one of America’s most inspirational figures.

Keller’s 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... Keller’s 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.
