Sir Ernest Rutherford, presidente de la Sociedad Real Británica y Premio Nobel de Química en 1908, contaba la siguiente anécdota: Hace algún tiempo, recibí la llamada de un colega. Estaba a punto de poner un cero a un estudiante por la respuesta que había dado en un problema de física, pese a que este afirmaba con rotundidad que su respuesta era absolutamente acertada. Profesores y estudiantes acordaron pedir arbitraje de alguien imparcial y fui elegido yo. Leí la pregunta del examen y decía: "Demuestre como es posible determinar la altura de un edificio con la ayuda de un barómetro". El estudiante había respondido: "lleva el barómetro a la azotea del edificio y átale una cuerda muy larga. Descuélgalo hasta la base del edificio, marca y mide. La longitud de la cuerda es igual a la longitud del edificio". Realmente, el estudiante había planteado un serio problema con la resolución del ejercicio, porque había respondido a la pregunta correcta y completamente. Por otro lado, si se le concedía la máxima puntuación, podría alterar el promedio de su año de estudios, obtener una nota mas alta y así certificar su alto nivel en física; pero la respuesta no confirmaba que el estudiante tuviera ese nivel. Sugerí que se le diera al alumno otra oportunidad. Le concedí seis minutos para que me respondiera la misma pregunta pero esta vez con la advertencia de que en la respuesta debía demostrar sus conocimientos de física.

His model assumed that (1) the electron exists on precise circular orbits around the nucleus, (2) as long as an electron remains in one orbit, no energy is given off, and (3) the angular momenta associated with allowed electron motion are integral multiples of . Bohr introduced the Correspondence Principle, which states that quantum mechanical formulas must reduce to the classical results in the limit of large quantum number. He also advocated a probabilistic interpretation of quantum mechanics known as the Copenhagen Interpretation In 1922 he was awarded the Nobel Prize in physics for this work.

October 7 ~  A Profound Truth Niels Bohr Gentle Genius "The o p p o s i t e of a profound t r u t h may well be a n o t h e r profound truth ." ~ Niels Bohr One of the leading figures of modern science, Danish physicist Niels Henrik David Bohr (1885-1962) was born on this day, studied at Copenhagen University, and was a professor there. "If an idea does not appear bizarre, there is no hope for it," he once said. In 1912, Bohr moved to England and worked with the Nobel Prize -winning scientist Ernest Rutherford to better understand the structure of the atom. Their research combined quantum theory with atomic structure and showed the atom's center nucleus with electrons, fixed in orbit from the nucleus. "When it comes to atoms," Bohr said, "language can be used only as in poetry . The poet, too, is not nearly so concerned with describing facts as with creating images." Bohr is well-known for his friendly debates with Albert Einstein about quantum theory. "Not often in life has a man given me so much happiness by his mere presence as you have done," Einstein wrote to Bohr. "I have learned much from you, mainly from your sensitive approach to scientific problems."

Last updated: 05.08.2001 06:34:02 Niels Bohr was born in Copenhagen in Denmark in 1885. His father was a professor of physiology at the University of Copengagen. Niels attended the same university and was a distinguished soccer player as well as a brilliant student. Bohr studied at J. J. Thomson ´s Cavendish Laboratory and at Rutherford ´s laboratory. At the young age of 28, while working with Rutherford, he invented the first effective model and theory of the structure of the atom. His work ranks as one of the truly great examples of an imaginative mind at work. He was awarded the 1922 Nobel Prize for physics for his study of the structure of atoms. During Worls War 2, Bohr and his family escaped from occupied Denmark to the United States. He and his son, Aage, acted as advisers at the Los Alomos Atomic Laboratories, where the atom bomb was developed. Thereafter, Bohr concerned himself with developing peaceful uses of nuclear energy. Aage Bohr, Neil´s son was awarded the Nobel Prize for physics in 1975. Optimální rozlišení - 1024x768, minimálnì 800x600.

Web Links Niels Bohr Niels Bohr was born in Copenhagen on October 7, 1885, and earned his doctorate in Physics at the University of Copenhagen in 1911. In the autumn of 1911 he began working under J. J. Thomson at Cavendish Labroartory . There he began to work on the problem of the atom's structure. He was able to merge the Rutherford model of the atom with the new idea of quanta that had been put forth by Max Planck. This new model of the atom came to be known as the Bohr model, and won the 1922 Nobel Prize in Physics After Hitler took power in Germany, Bohr was deeply concerned for his colleagues there, and offered a place for many escaping Jewish scientists to live and work. In 1939 Bohr visited the United States with the news that German scientists were working on splitting the atom. Shortly after Bohr's return home, the German army occupied Denmark. Three years later Bohr's family fled to Sweden in a fishing boat. They ultimately went to the United States, where he joined the atomic bomb effort at Los Alamos. Bohr had qualms about the consequences of the bomb. After the war, Bohr spent the rest of his years in Denmark where he began work on the development of peaceful uses for atomic energy. In 1955 he organized the first Atoms for Peace Conference in Geneva, Switzerland. He died on November 18, 1962 in Copenhagen.

During World War II, the Bohr family fled to Sweden to avoid the Nazis. Shortly afterwards, Aage and his father went to England. During this time, Aage was acting as his father's assistant and secretary, sharing his father's research. In August 1945, they both returned to Denmark, and Aage resumed his studies, obtaining a master's degree in the following year with a thesis on some aspects of atomic stopping problems. In 1948, Aage joined the Institute for Advanced Study at Princeton University, and from there went to Columbia University, where he discussed a newly discovered effect in the hyperfine structure of deuterium with I.

Niels Bohr Memorial Bohr, Niels Henrik David (1885-1962), Danish physicist and Nobel laureate, who made basic contributions to nuclear physics and the understanding of atomic structure. Bohr was born in Copenhagen on October 7, 1885, the son of a physiology professor, and was educated at the University of Copenhagen, where he earned his doctorate in 1911. That same year he went to Cambridge, England, to study nuclear physics under the British physicist Sir Joseph John Thomson, but he soon moved to Manchester to work with Ernest Rutherford. Bohr's theory of atomic structure (see Quantum Theory), for which he received the Nobel Prize in physics in 1922, was published in papers between 1913 and 1915. His work drew on Rutherford's nuclear model of the atom, in which the atom is seen as a compact nucleus surrounded by a swarm of much lighter electrons (see Atom and Atomic Theory). Bohr's atomic model made use of quantum theory and the Planck constant (the ratio between quantum size and radiation frequency). The model posits that an atom emits electromagnetic radiation only when an electron in the atom jumps from one quantum level to another. This model contributed enormously to future developments of theoretical atomic physics. In 1916 Bohr returned to the University of Copenhagen as a professor of physics, and in 1920 he was made director of the university's newly formed Institute for Theoretical Physics. There Bohr developed a theory relating quantum numbers to large systems that follow classical laws, and made other major contributions to theoretical physics. His work helped lead to the concept that electrons exist in shells and that the electrons in the outermost shell determine an atom's chemical properties. He also served as a visiting professor at many universities.

Nov. 18, 1962, Copenhagen in full NIELS HENRIK DAVID BOHR Danish physicist who was the first to apply the quantum theory, which restricts the energy of a system to certain discrete values, to the problem of atomic and molecular structure. For this work he received the Nobel Prize for Physics in 1922. He developed the so-called Bohr theory of the atom and liquid model of the atomic nucleus. Early life  Bohr's father, Christian Bohr, professor of physiology at the University of Copenhagen, was known for his work on the physical and chemical aspects of respiration. His mother, Ellen Adler Bohr, came from a wealthy Jewish family prominent in Danish banking and parliamentary circles. Bohr's scientific interests and abilities were evident early, and they were encouraged and fostered in a warm, intellectual family atmosphere. Niels's younger brother, Harald, became a brilliant mathematician. Bohr distinguished himself at the University of Copenhagen, winning a gold medal from the Royal Danish Academy of Sciences and Letters for his theoretical analysis of and precise experiments on the vibrations of water jets as a way of determining surface tension. In 1911 he received his doctorate for a thesis on the electron theory of metals that stressed the inadequacies of classical physics for treating the behaviour of matter at the atomic level. He then went to England, intending to continue this work with Sir J.J. Thomson at Cambridge.

Niels Bohr (1885-1962) Short biography Niels Bohr was born in Copenhagen on October 7, 1885. His father was a professor (physiology) a the university of Copenhagen. On his mother's side, he was of jewish descent. Bohr had an older sister, Jenny, and a brother Harald, who became a famous mathematician. In 1911, Bohr finished his doctoral work on the electron theory of metals. He did postdoctoral studies in 1912 and 1913 in England, first in Cambridge under Thomson (who discovered the electron), then in Manchester, under Rutherford. Rutherford had just discovered the atomic nucleus. The young Bohr proved able to unify the new discoveries into a theory, that permitted prediction of atomic spectra for atoms with one electron. The archetypical representation of the atom, also present as an icon on this page, is derived from Bohr's theory. Bohr published his insights in 1913. A most important aspect of his theory was the introduction of Planck's constant in atomic theory. Moreover, his theory introduced a profound break with classical mechanics. The discontinuous 'quantum jump' is a basic part of the theory. In 1922, Bohr received the Nobel prize 'for his investigations of the structure of atoms and of the radiation emanating from them'. In that same year, he met the young physicists Heisenberg and Pauli. Bohr, Heisenberg and Pauli were going to constitute the kernel of the Copenhagen School in physics.
