First seperate edition of a lecture delivered by Bohr before the Physical Society of Copenhagen on October 18, 1921. In this lecture Bohr attacked the problem of atomic constitution by asking the question: ""How may an atom be formed by the successive capture of the electrons one by one in the field of force surrounding the nucleus?"" The answers are found primarly from an analysis of the observed spectra with quidance from the chemical properties and the correspondance principle. (Collected Works, vol. 4, pp.20). The lecture was quickly translated into German and published in 'Zeitschrift für Physik'

The work is inscribed to renowned Danish physicist and meteorologist Dan la Cour (1876-1942), son of the great Poul la Cour (1846-1908), who is considered the ""Danish Edison"". Dan la Cour was the assistant of Niels Bohr's father, Christian Bohr, and a well known scientist. From 1903, he was head of the department of the Meteorological Institute, and from 1923 leader thereof. From 1908 he was Associate Professor at the Polytechnic College. His original scientific works are highly respected, as are his original apparati for measuring earth magnetism which are considered highly valuable. ""His original intelligence, which in many ways resemble that of his father, also bore fruit in his patenting of various inventions: the ""Pyknoprobe"", developed to quickly determine the different layers of the sea"" a use of termite in quickly heating food and drinks out in the open under unfavourable weather conditions."" (From the Danish Encyclopaedia - own translation). He wrote a number of important and esteemed works and was member of the Danish Scientific Academy as well as many prominent international scientific commissions of meteorology and geophysics (i.e. president of the International Geodetical and Geophysical Union). He was also honorary Doctor at the George Washington University. Rosenfeld, Bohr Bibliography No. 40.

The subject was to experimentally investigate a method, proposed by Lord Rayleigh, for measuring the surface tension of water by the observation of a regularly vibrating jet. ""Bohr [...] included in his work essential improvements on Rayleigh's theory by taking into account the influence of the liquid's viscosity and of the ambient air, and by extending the earlier theory from infinitesimal to arbitrary large vibration amplitudes.

One of the few scarce original stenciled copies of the ""Journal of Jocular Physics, Vol. III,"" the 1955-volume of the privately circulated amateur-comedy-journal that Bohr's students made on the occasions of Bohr's most important birthdays (beginning with his 50th in 1935), in this case his 70th. The ""Journal"" is an eclectic blend of funny and clever stories, songs, poems, aphorisms, humorous descriptions of recent developments in physics, etc., all written in an informal tone with the underlying subject being Bohr's birthday.Since 1929 most of the greatest physicists of the 20th century had been gathering around Niels Bohr for a conference in Copenhagen at the Bohr Institute. Since 1931 this conference had also included a skit prepared by the youngest of the participants, the ""Copenhagen Faust"" of 1932 being the most famous and important of them. It is this skit that later develops into the ""Journal of Jocular Physics"" which was prepared and compiled for Bohr's 50th, 60th and 70th birthdays, the first in 1935, the second in 1945, and the third (the present) in 1955. The 1955 ""Jocular Physics"" was the last of them. ""The early decades of the present century witnessed the heady development of the Quantum Theory of the atom, and during that era the roads of theoreticians of all nationalities led, not to Rome, but to Copenhagen, the home city of Niels Bohr, who was the first to formulate the correct atomic model. It became customary at the end of each spring conference at Blegdamsvej 15 (the street address of Bohr's Institute of Theoretical Physics) to produce a stunt pertaining to recent developments in physics.However Copenhagen was also the home of abundant humor. As a respite from the intensive and highly competitive efforts taking place to characterize fundamental interactions on an atomic scale, physicists took the time to develop satirical letters, articles, plays and other works."" (Gamow, Thirty Years that Shook Physics, pp. 167-68).In his Report at the Niels Bohr Archive Symposium, ""Copenhagen' and beyond: Drama meets history of science"", Yu.V. Gaponov accounts for the history of ""physical art"": ""The 1950s and 1960s were the golden age of the utmost prosperity in Physics. The atomic revolution having opened for the scientists a new world of quanta led soon to the nuclear fission discovery and to the first steps in techniques to dominate the atomic energy. The realization of national atomic programs which first took place in USA and then in Russia (USSR) and Great Britain had attracted the whole world's attention and placed Physics and the natural sciences in general in a top position. Being concerned with matters of physics became then exclusive and prestigious and physicists as individuals attracted the society's attention. They became heroes of literature, theater, movies, press. This process was observed in many advanced countries. It was also typical for the former USSR of those times, although owing to special social circumstances it had acquired some particular forms. One such form was the creation of ""Physical Art"" traditions... The birth of these traditions is commonly associated with the appearance at MSU PhysFac in 1960 of a Student Humor Festival called ""Birthday of Archimedes"" (later ""Physics Day"") along with a comic buffoonery opera ""Archimedes"" (authors - physicists and poets V. Kaner, V. Milyaev). However, MSU physicists consider the ""Physical Art"" traditions to have started earlier.

First edition of Bohr's seminal main work, which constitutes the departure from classical theories" by incorporating Planck's quantum postulate it became possible to calculate the wavelength of the hydrogen emission and thus to explain the regularity of the Balmer-lines.In his previous paper (""On the Theory of Decrease of Velocity of Moving Electrified Particles on passing through Matter"") Bohr had adopted Rutherford's nuclear model of the atom, and had become convinced that it was the peripherical electrons that determined the chemical properties of an element, whereas the nucleus determine the radioactive properties. However, Rutherford's model had an apparent explanatory problem: Why were the negatively charged electrons held away from the positive nucleus? In his doctorial dissertation on the electron theory of metals, Bohr had clarified the limitations of this theory, in particular its ability to explain magnetic properties, and he had shown how this arose from the classical nature of some of its foundations. Bohr strongly expected that the key to solving this problem was to be found in some way of introducing Planck's law of quantum action.In the beginning of 1913 Bohr heard about Rydberg's remarkable discovery in spectroscopy. Rydberg's formula could represent the frequencies of the lines of the hydrogen spectrum in the simplest form in terms of two integers. As soon as Bohr saw this formula, he immediately recognized that it gave him the missing clue to the correct way to introduce Planck's law of quantum of action into the description of the atomic systems. The rest of the academic year was spent reconstructing the whole theory upon the new foundation and expounding it in a large treatise, which was immediately published as these three papers in the 'Philosophical Magazine'. It was in these papers that Bohr first gave his postulates of the orbital structure of the electrons and their quantized radiation.Bohr's atomic theory inaugurated two of the most adventurous decades in the history of science. In 1922 Bohr was awarded the Nobel Prize ""for his services in the investigation of the structure of atoms and of the radiation emanating from them"".Bohr introduced the following postulates: 1. An electron can revolve about its nucleus only in certain special circular orbits. 2. The ordinary electron revolves about its nucleus in an invariable orbit, without radiating or absorbing energy. 3. Radiation takes place when and only when the electron falls from an orbit with greater energy to one of less energy.Rosenfeld, Bohr Bibliography No. 6.
