This was, however, not achieved by Bohr through giving the electrons some kind of wave-like properties, since the idea that electrons could behave as matter waves was not suggested until twelve years later.

In October 1943, shortly before he was to be arrested by the German police, Niels Bohr escaped to Sweden with his family, later travelling to London and on to work on the Manhattan Project.

Bohr worked at the Institute for Advanced Study in Princeton in early 1948, and later at Columbia University from January 1949 to August 1950.

Still, Thomson's model ( along with a similar Saturnian ring model for atomic electrons, also put forward in 1904 by Nagaoka after James Clerk Maxwell's model of Saturn's rings ), were earlier harbingers of the later and more successful solar-system-like Bohr model of the atom.

The Soviet ( later, Russian ) team proposed the name nielsbohrium ( Ns ) in honor of the Danish nuclear physicist Niels Bohr.

Furthermore, as noted by Bohr, Moseley's law provided a reasonably complete experimental set of data that supported the ( new from 1911 ) conception by Ernest Rutherford and Antonius Van den Broek of the atom, with a positively-charged nucleus surrounded by negatively-charged electrons in which the atomic number is understood to be the exact physical number of positive charges ( later discovered and called protons ) in the central atomic nuclei of the elements.

He studied at the Institute for Theoretical Physics of the University of Copenhagen ( later to become the Niels Bohr Institute ), and Technical University of Denmark.

Years later it became a favorite book of the Danish physicist and thinker Niels Bohr, who often quoted it during lectures.

The constant first arose as an empirical fitting parameter in the Rydberg formula for the hydrogen spectral series, but Niels Bohr later showed that its value could be calculated from more fundamental constants, explaining the relationship via his " Bohr model ".

In Berlin, he met two physicists who would later be significant to the biology community: Niels Bohr and Max Delbrück.

Rutherford's model was later elaborated into the Bohr model by physicist Niels Bohr in 1913.

A later conference would include Niels Bohr, Werner Heisenberg, Max Born, and Erwin Schrödinger.

He moved to Institute for Theoretical Physics ( later the Niels Bohr Institute ) in Copenhagen on the Sheldon Traveling Fellowship from Harvard, and remained in Denmark, becoming a professor at the newly formed Nordic Institute for Theoretical Physics ( Nordita ) in 1957.

The concept was first studied by Harald Bohr and later generalized by Vyacheslav Stepanov, Hermann Weyl and Abram Samoilovitch Besicovitch, amongst others.

Like his father and brother before him, in 1904 Bohr enrolled at the University of Copenhagen, where he studied mathematics, obtaining his masters in 1909 and his doctorate a year later.

His book Brighter than a Thousand Suns: A Personal History of the Atomic Scientists was the first published account of the Manhattan Project and the German atomic bomb project, and its first Danish edition included a passage which implied that the project had been purposely dissuaded from developing a weapon by Werner Heisenberg and his associates ( a claim strongly contested by Niels Bohr ), and lead to a series of questions over a 1941 meeting between Bohr and Heisenberg in Copenhagen, Denmark, which was later the basis for Michael Frayn's 1998 play, Copenhagen.

Heisenberg is best known for his “ Uncertainty Principle ,” ( translated from the German Ungenauigkeit or Unschärfe of sharpness Relation, which was later changed to Unbestimmtheit meaning “ indeterminate .”) In 1927, he and Bohr presented the Copenhagen interpretation of quantum mechanics.

* Margrethe Bohr, known later in her life as Dronning or “ Queen ” Margrethe, was born in 1890 in Denmark.

) According to Bohr's later notes, Heisenberg then told Bohr that he had not come to discuss the technical aspects of the potential weapons:

Heisenberg had hoped to convey his concerns later during private discussions with Bohr.

That Supek stated that Margrethe believed that Weizsäcker was present and that Bohr recalled this private meeting as taking place " in my room at the Institute ", where Heisenberg and Weizsäcker had made their public statements may suggest that Bohr blurred two events and did not distinguish between the public statements Heisenberg made and the private message Heisenberg hoped to convey to Bohr later that evening at Bohr's house.

By the late 1940s it was known that the properties of atomic nucleus could not be explained by the then-current models ( such as the liquid drop model developed by Niels Bohr amongst others ).

The first isotope separator was developed at the Copenhagen Cyclotron by Bohr and co-workers using the principle of electromagnetic separation.

Lakoff's reliance on empirical scientific evidence, i. e. specifically falsifiable predictions, in the 1987 work and in Philosophy in the Flesh ( 1999 ) suggests that the cognitive-metaphor position has no objections to the scientific method, but instead considers the scientific method a finely developed reasoning system used to discover phenomena which are subsequently understood in terms of new conceptual metaphors ( such as the metaphor of fluid motion for conducted electricity, which is described in terms of " current " " flowing " against " impedance ," or the gravitational metaphor for static-electric phenomena, or the " planetary orbit " model of the atomic nucleus and electrons, as used by Niels Bohr ).

This was, at first, followed by a heuristic framework devised by Arnold Sommerfeld and Niels Bohr, but this was soon replaced by the quantum mechanics developed by Max Born, Werner Heisenberg, Paul Dirac, Erwin Schrödinger, and Wolfgang Pauli.

Niels Bohr, who developed the Bohr Model of the atom, said,

In 1950 – 51, James Rainwater and Aage Bohr had developed models of the atomic nucleus which began to take into account the behaviour of the individual nucleons.

Schrödinger's equation developed the idea from a flat two-dimensional Bohr atom to the three-dimensional wave function model.

It was first proposed by George Gamow and then developed by Niels Bohr and John Archibald Wheeler.

The principle was developed and introduced by Niels Bohr in 1927.

At the time quantum mechanics was developed in the 1920s, the momentum operator was found by many theoretical physisists, including Niels Bohr, Arnold Sommerfeld, Erwin Schrödinger, and Eugene Wigner.

He suggested a new synthesis of the Bohr theory of quasiperiodic functions and developed methods for asymptotic integration of nonlinear differential equations which describe oscillating processes.

However, the idea that electrons might revolve around a compact nucleus with definite angular momentum was convincingly argued at least 19 years earlier by Niels Bohr, and the Japanese physicist Hantaro Nagaoka published an orbit-based hypothesis for electronic behavior as early as 1904.

Bohr, visiting Columbia at the time, had independently conceived the same idea, and submitted a paper for publication about a month after Rainwater's which discussed the same problem along more general lines.

The physical interpretation of the theory was also clarified in these years after Werner Heisenberg discovered the uncertainty relations and Niels Bohr introduced the idea of complementarity.

Born's idea was soon taken over by Niels Bohr in Copenhagen who then became the " father " of the Copenhagen interpretation of quantum mechanics.

There he explained to Bohr and Kramers his original idea that classical radiation fields guided light quanta, a sort of forerunner of the duality principle.

After a brief stay at the University of Cambridge, he went on to the University of Copenhagen, where " he explained to Bohr and Kramers his idea ( that was ) a sort of forerunner of the duality principle, ( hence ) the celebrated paper " on the work that others dubbed the Bohr-Kramers-Slater ( BKS ) theory.

Bohr was one of the most vocal opponents of the photon idea and did not openly embrace it until 1925.

His idea contemplates the existence of an experimental apparatus which was subsequently designed by Bohr in such a way as to emphasize the essential elements and the key points which he would use in his response.

Bohr had concluded that they would have both drowned had he jumped in to save his son, and this presents an idea of futile heroics, particularly with reference to Heisenberg and what should happen if he were to resist Hitler ’ s rule.

It was not until the work of Henry Moseley working with the Bohr model of the atom with the explicit idea of testing van den Broek's theory, that it was realized that atomic number was indeed a purely physical property ( the charge of the nucleus ) which could be measured, and that van den Broek's original guess had been correct, or very close to correct.
