Steemhomework for the week" Marie Curie "

MARIE CURIE, (MARIA SALOMEA SKLODOWSKA), was born in Warsaw, on November 7, 1867, a Polish nationalized French scientist, her studies took place in the "Polish Floating University", she began her practical scientific training between 1890-1891 in the chemical laboratory of industry and agriculture of Warsaw, at the end of 1891 he left for France to continue his studies, physics, mathematics and chemistry, at the University of Paris. Being self-taught in the learning of the French language, he obtains the degree in physics 1893 and the following year the degree in chemistry.

In 1894 he began research on the magnetic properties of various steels, for this year he met Pierre Curie. French physicist Born in Paris on May 15, 1859 who was part of the science faculty of the Sorbonne or historic university of Paris France. Facts presented by the Polish physicist Josef Kowalski-wierusz, since Marie was in search of a laboratory with more work space, where he could find a place in Pierre's laboratory and there they were joined by a great friendship and interest in science to the point that Marie said she had found a new love, partner and scientific collaborator in whom she could trust, a time later on July 26, 1895, they strengthened ties in marriage.

During 1896, she started with her husband the study of radioactivity, discovered by the French physicist Henri Becquerel, works that led to the discovery of the existence of two new elements in 1898; such as the radium (atomic number 88 in the periodic table), highly radioactive, and polonium (atomic number84), the name the latter receives in honor of Marie's birthplace

Since then, Marie concentrated on obtaining the metallic radius, which she achieved with the collaboration of A.Debierne, while her husband Pierre studied the chemical, physiological and luminous properties of the radioactive

After the death of her husband Pierre, being hit by a car in 1906, Marie continued the work and founded the radio institute (1914), in which I carry out a deep study of the applications of X-rays and radioactivity in fields of medicine.
The Curies were able to determine from their experiments that when the human being is exposed to the radius the diseased and tumor-forming cells were destroyed faster than the healthy cells.

Contributions from the studies and experiments of the Curie spouses

• In 1880 Pierre Curie together with his brother Jacques discovered piezoelectricity, a phenomenon in which compressing a crystal (quartz) generates an electrical potential. Under this principle, vibration and pressure sensors are currently based, as well as the design of piezoelectric fuel injectors in automobiles.
• 1894 Pierre enunciated the universal principle of symmetry: the symmetries present in the causes of a physical phenomenon are found in their consequences.
• The studies and research of magnetism, ferromagnetism, paramagnetism very diamagnetism resulted in the discovery of the effect of temperature on paramagnetism (Curie's law) as well as discovered that ferromagnetic substances have temperature above which they lose their ferromagnetic character, which is known as Curie point
• In 1903 he received the Nobel Prize in Physics together with his wife Marie and Henri Becquerel in recognition of their research on radioactivity.
• In 1911 Marie Curie was awarded the Nobel Prize for Chemistry for the discovery of radio and polonium elements, among other contributions
• During the First World War, Marie Curie traveled through hospitals to help surgeons apply radiology techniques and related to radioactivity. Design of mobile radiography units that I call radiological ambulances, which were later known as "little Curie"
• Thanks to their studies, the "Curie Institute of Radio", directed by Marie Curie, was founded together with the Sorbonne and the Pasteur Institute

MARIE CURIE

Supreme benefactor of humanity", this is how she was called Maria Sklodowska-Curie, better known as Marie Curie, one of the women who made great contributions to chemistry and physics
