Niels Henrik David Bohr (1885-1962) Niels Henrik David Bohr, 1885'de Copenhagen Universite 'sinde fizyoloji profesörü Christian Bohr'un oðlu olarak dünyaya geldi. Niels ve küçük kardeþi Harald(geleceðin matematik profesörü) geliþimi için çok olumlu bir atmosferde büyüdü, Babasý çok seçkin bir profesördü. Onun okul yýlarýnda fizikle ilgilenmesinde büyük etkisi olmuþtur. Annesi de eðitim alanýnda önemli kiþilerden biriydi. 1903' de Gammelholm Grammar okuluna girdikten sonra çok seçkin ve yetenekli bir profesör olan C. Christiansen 'in danýþmanlýðýnda Copenhagen Universite'sine girdi. Master derecesini 1909'da doktorasýný 1911'de aldý. Daha öðrenciyken Copenhagen'daki bilimler akademisi tarafýndan bazý özel bilimsel problemlerin çözümü için ödül verileceði duyrulunca, Bohr akýþkanlarýn yüzey gerilimi konusunda deneysel ve teorik araþtýrma yapmaya baþladý. Babasýnýn laboratuvarlarýnda yaptýðý bu çalýþmayla duyurulan ödülü aldý. Bohr'un bundan sonraki çalýþmalarý daha çok teorikti. Doktora tezi tamamen teorik ve günümüzünde klasik problemlerinden olan, elektron teorisi yardýmýyle metallerin özelliklerinin açýklanmasýydý. Bu teoriyle ilk defa Bohr, Planck 'ýn quantum teorisiyle çatýþtý.

Detaljeret om indholdet i enkelte mapper Overordnet beskrivelse af samlingen Kort beskrivelse: Denne samling består bl.a. af manuskripter, notater, korrespondance, nekrologer og avisartikler. Omfangsmæssigt udgøres størstedelen af samlingen dels af materiale vedrørende Bohrs undervisning og dels af materiale i forbindelse med udgivelsen af Bohrs Collected Mathematical Works i 1952-53. Undervisningsmaterialet omfatter en stor del af hans forelæsningsmanuskripter og hans eksemplarer af anvendte lærebøger med kommentarer. Faktisk alt materiale fra udgivelsen af Collected Mathematical Works er bevaret, dvs. plan for værkerne, korrespondance med forlag, redaktører etc. Det biografiske materiale i samlingen er særtryk af de fleste nekrologer om Bohr, avisudklip om Bohr, en del billeder af ham og forskellige personlige papirer. Korrespondancen er udelukkende videnskabelig korrespondance og iøvrigt kun en meget lille del af Bohrs samlede videnskabelige korrespondance. De videnskabelige manuskripter og notater er næsten alle fra Bohrs studietid 1904-10. Endvidere er der en samling taler, som Bohr har holdt ved forskellige lejligheder. Materialet som helhed er fra perioden 1904-65 og på sprogene dansk, tysk, engelsk og fransk med hovedparten på dansk.

His model assumed that (1) the electron exists at precise distances from the nucleus, (2) as long as an electron remains in one location, no energy is given off, (3) electrons have circular orbits (this is only correct for s orbitals), and (4) the angular momenta associated with allowed electron motion are integral multiples of . Bohr stated the Correspondence Principle, which states that quantum mechanical formulas must reduce to the classical results in the limit of large quantum number.

He entered the Copenhagen University in 1940, following the steps of his father. By that time, Aage was already assisting his father with mail and writing papers. 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.

The Bohr Model of the Atom Go to "Bohr Model - Part 2" Return to Electrons in Atoms menu On June 19, 1912, Niels Bohr wrote to his brother Harald: "Perhaps I have found out a little about the structure of atoms." I. Setting the Stage The Bohr model of the atom deals specifically with the behavior of electrons in the atom. In constructing his model, Bohr was presented with several problems. Problem #1: charged electrons moving in an orbit around the nucleus SHOULD radiate energy due to the acceleration of the electron in its orbit. The frequency of the emitted radiation should gradually change as the electron lost energy and spiraled into into the nucleus. Obviously this was not happening, because the spectral lines of a given element were sharply defined and unchanging. Problem #2: the spectral lines did not show overtones (or harmonics). These are lines where the frequency is double, triple and so on of the fundamental frequency. The lines of the spectrum of each element were scattered about with no apparent pattern, other than the purely empirical formula of Balmer (which dates to 1885). However, no one knew what Balmer's formula meant. cm.) and allow the electrons to distribute themselves inside. The calculations for his "plum pudding" model, published in 1904, showed that the model did produce electron arrangements that were stable.
