Extractions: Bohr Comes to Cambridge In 1911, the 26-year-old Niels Bohr earned a Ph. D. at the University of Copenhagen; his dissertation was titled "Studies on the Electron Theory of Metals". He was awarded a postdoctoral fellowship funded by the Carlsberg Brewery Foundation, which enabled him to go to Cambridge in September to study with J. J. Thomson. Bohr was a great admirer of Thomson's many achievements, both experimental and theoretical. In his thesis work, he had closely studied some of the problems covered in Thomson's book Conduction of Electricity through Gases. He had uncovered some apparent errors in Thomson's work, and looked forward to discussing these points with the great man. Unfortunately, by the time Bohr arrived, the Cavendish Laboratory had grown to the point where Thomson as director had more than he could manage. He had no spare time to think about electrons, and was not happy to hear from Bohr that some of his earlier work might be incorrect. In fact, Thomson went out of his way to avoid theoretical discussions with Bohr (Pais, page 195). He did assign Bohr an experiment on positive rays, but Bohr was not enthusiastic. (Rhodes, page 65) Bohr kept himself busy writing a paper on electrons in metals, reading Dickens to improve his English, and playing soccer. In December, Rutherford came down from Manchester for the annual Cavendish dinner. Bohr later said that he was deeply impressed by Rutherford's charm, his force of personality, and his patience to listen to every young man who might have an ideacertainly a refreshing change after J. J.! A little later, Bohr met with Rutherford again when he visited one of his father's friends in Manchester, someone who also knew Rutherford. Although Rutherford was usually skeptical of theorists, he liked Bohr. For one thing, Rutherford was a soccer fan, and Bohr's brother Harald (only nineteen months younger than Bohr) was famoushe had played in the silver medal winning Danish soccer team at the 1908 Olympics in London.
From Bohr's Atom To Electron Waves harald bohr wrote to his brother from Göttingen in the fall of 1913 that theyoung physicists there considered bohr's model too bold and fantastic . http://www.phys.virginia.edu/classes/252/Bohr_to_Waves/Bohr_to_Waves.html
Extractions: Reactions to Bohr's Model Bohr's interpretation of the Balmer formula in terms of quantized angular momentum was certainly impressive, but his atomic model didn't make much mechanical sense, as he himself conceded. For example, an electron jumping from the n th orbit to the m th emitted radiation at frequency equal to the energy difference of the orbits divided by h . Presumably, it began radiating as soon as it left its original orbit. As Rutherford put it in a letter to Bohr, "how does an electron decide what frequency it is going to vibrate at when it passes from one stationary state to another? It seems to me that you would have to assume that the electron knows beforehand where it is going to stop." A few days later, Bohr sent Rutherford another manuscript containing the correspondence principle argument gone over in our last lecture. This was a bit too long for Rutherford. He responded: "As you know, it is the custom in England to put things very shortly and tersely in contrast to the Germanic method, where it appears to be a virtue to be as long-winded as possible". Mysterious Spectral Lines One good reason for the Germanic skepticism was the recent discovery of apparently new spectral lines for hydrogen corresponding to half -integers in the Balmer formula. These new lines had been seen by a spectroscopist, Alfred Fowler, in a discharge tube containing a mixture of hydrogen and helium, and also in the spectra of a star by Pickering.

Extractions: Die Person Niels Bohr Niels Hendrik David Bohr wird am 7. Oktober 1885 in Kopenhagen, Dänemark, geboren. Sein Vater, Christian, ist Wissenschaftler, ein Physiologe an der Kopenhagener Universität. Seine Mutter, Ellen, stammt aus einer prominenten Bänkerfamilie. Niels nimmt zwar die Konfession seiner Mutter, die Jüdin ist, an, erklärt aber im Alter von 18 Jahren, Religion bedeute ihm nichts. Dies ist auch auf den Einfluß seines Vaters zurückzuführen, der selber nicht gläubig und daher auch nicht kirchlich getraut ist. Niels hat eine ältere Schwester Jenny , sowie einen jüngeren Bruder, Harald. Jenny und Harald waren beide auch sehr begabt. Jenny studierte in Kopenhagen und Oxford und wurde eine hervorragende Lehrerin, die wegen ihrer Herzlichkeit überall geschätzt wurde. Trotzdem war sie nach einiger Zeit ein nervliches Wrack und wurde in eine Nervenheilanstalt eingeliefert. In ihrer Sterbeurkunde steht, sie starb ``in der manischen Phase einer manisch depressiven Psychose'' [ Sein jüngerer Bruder Harald, später Professor für Mathematik in Kopenhagen, promovierte noch vor Niels und entschied sich für Deutschland

Extractions: Instituto Niels Bohr, Denmark Su amistad con Einstein Einstein le escribió una vez a Bohr: "Not often in life has a man given me so much happiness by his mere presence as you have done," ("Muy pocas veces en mi vida un hombre me ha dado tanta felicidad con su mera pesencia como vos lo hiciste") y también "I have learned much from you, mainly from your sensitive approach to scientific problems." ("Aprendí tanto de vos, especialmente de tu sensibilidad en el acercamiento a los problemas científicos") A Einstein le gustaba inventar frases como "God does not play dice" ("Dios no juega a los dados") o "The Lord is subtle but not malicious" ("El Señor es sutil pero no malicioso"). En una oportunidad Bohr respondió "Einstein, stop telling God what to do" ("Einstein, dejá de decirle a Dios lo que tiene que hacer") Nota: en su juventud Bohr era todo un atleta y dentro de la cancha de fútbol se lo consideraba inferior únicamente a su hermano, el conocido matemático Harald, "indiscutiblemente el mejor guardavalla del equipo de Copenhague" según George Gamow.
BOHR ON EPR, AS INFLUENCED BY JAMES AND KANT, PART I harald Hoffding had visited William James in America in 1904, duringwhich time bohr was Hoffding's immediate student. However http://www.geocities.com/saint7peter/BohronEPRI.html
Extractions: PART I Concerning my essay, entitled "THE METAPHYSICAL MESSAGE OF BOHR, JAMES, AND GOETHE", I should probably contextualize its relevance. My intent was simply to make coherent sense of Bohr's quintessential statements on EPR by comparing them to the statements of James and of Goethe. Henry Stapp has retracted his comment (which was quoted in my essay) on Bohr's first statement because readers found Bohr's statement bewildering and obscure without further contextualization. I have provided that contextualization for anyone who has the intellectual integrity to investigate the matter deeply. For those who simply hate the orthodox interpretation, nothing I nor anyone else could say can ever convince them, but their irrational hatred and resistance is proof positive that the orthodox interpretation is the correct one. Why William James? Bohr's statement in an interview conducted one day before his death was: "William James is really wonderful in the way he makes it clear - I think I read 'The Stream of Thought'. I know something about William James. I thought he was most wonderful." James actually featured in an arguably relevant way the terms "complementary" and "superposition" 35 years before they were employed as central doctrines of quantum theory. "The Stream of Thought" begins on p. 224 of the first volume of "The Principles of Psychology". On p. 206 we find the following: "It must be admitted, therefore, that in *certain persons*, at least, *the total possible consciousness may be split into parts which coexist but mutually ignore each other*, and share the objects of knowledge between them. More remarkable still, they are *complementary*. Give an object to one of the consciousnesses, and by that fact you remove it from the other or the others."

Extractions: Margrethe Norlund and Niels Bohr engaged, 1911 Margrethe Norlund grew up the daughter of a pharmacist in the small Danish town of Slagelse, some 50 miles south-west of Copenhagen. She was studying French for a private teacher's certificate, when in 1910 she met the brothers Niels and Harald Bohr, friends of her own brothers. A year later she was engaged to Niels, and in 1912 they were married in a brief civil ceremony. They had six sons. Photo credits In the early 30s, the Danish government honored Niels by moving him and his family into the "Residence of Honor," a palatial mansion on the Carlsberg Brewery grounds reserved for the country's foremost scientist. There, Margrethe officiated with great warmth and charm over the many receptions held for visiting scientists and high dignitaries, from England's Queen Elizabeth II to the Indian Prime Minister Jawaharlal Nehru.

Extractions: Niels Bohr, 1925 Niels Bohr was one of the most influential scientists of the 20th Century and a major force in the field of quantum physics. He won the 1922 Nobel Prize in physics for his study of the structure and radiation of atoms. [See the animation of "The Bohr Atom", below, right.] Bohr recognized that Ernest Rutherford's model of the atom, in which electrons emitted radiation continuously, was unstable according to the laws of classical physics. Bohr postulated that radiation is emitted from atoms not as a result of the periodic motion of the electron in its orbit, but only when an electron "jumps" from one orbit to another losing energy that is emitted as radiation. Bohr's theory of the compound nucleus , in which the repulsion between positively charged protons is countered by huge amounts of energy in order to hold the nucleus together, helped lead to the hypothesis that splitting an atom would produce enough energy to fabricate a powerful weapon. Bohr's father was a well-known Danish physiologist, his mother came from a wealthy family of Jewish bankers. Bohr earned his Ph.D. at the University of Copenhagen in 1911, then worked in Cambridge, England with J.J. Thomson, discoverer of the electron, and in Manchester with Rutherford, who proposed the first nuclear model of the atom.
