Prize motivation: "for his services in the investigation of the structure of atoms and of the radiation emanating from them.
Niels Bohr postulates the atomic model which states that electrons move in specific circular orbits around the nucleus with quantised kinetic and potential energies. Ernest Rutherford said that atom consists of the whole mass that is concentrated into the centre. From the above statement, we can say that both the models of the atom differ in the way they explained the movements of electrons around the nucleus and their energy levels.

In atomic physics, the Bohr model depicts an atom as a small, positively charged nucleus surrounded by electrons. These electrons travel in circular orbits around the nucleus—similar in structure to the solar system, except electrostatic forces rather than gravity provide attraction. The Bohr model was an improvement on the earlier cubic model , the plum-pudding model , the Saturnian model , and the Rutherford model Since the Bohr model is a quantum-physics-based modification of the Rutherford model, many sources combine the two: the Rutherford—Bohr model. While the Rydberg formula had been known experimentally, it did not gain a theoretical underpinning until the Bohr model was introduced. Not only did the Bohr model explain the reason for the structure of the Rydberg formula, it also provided a justification for its empirical results in terms of fundamental physical constants.

Rutherford and Bohr
Sadoway discusses the atomic spectra of hydrogen Session 4. Lecture Slides PDF - 9. Periodic Table and Table of Constants. Sadoway talks about the principles of modern chemistry and how that led to the understanding of the structure of the atom.
The Rutherford model was devised by the New Zealand-born physicist Ernest Rutherford to describe an atom. Rutherford directed the Geiger—Marsden experiment in , which suggested, upon Rutherford's analysis, that J. Thomson 's plum pudding model of the atom was incorrect.
Rutherford model , also called Rutherford atomic model, nuclear atom , or planetary model of the atom , description of the structure of atoms proposed by the New Zealand-born physicist Ernest Rutherford. The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents , called electrons , circulate at some distance, much like planets revolving around the Sun. The atom , as described by Ernest Rutherford , has a tiny, massive core called the nucleus.
Однажды вечером на университетском представлении Щелкунчика Сьюзан предложила Дэвиду вскрыть шифр, который можно было отнести к числу базовых. Весь антракт он просидел с ручкой в руке, ломая голову над посланием из одиннадцати букв: HL FKZC VD LDS В конце концов, когда уже гасли огни перед началом второго акта, его осенило. Шифруя послание, Сьюзан просто заменила в нем каждую букву на предшествующую ей алфавите. Для расшифровки Беккеру нужно было всего лишь подставить вместо имеющихся букв те, что следовали непосредственно за ними: А превращалось в В, В - в С и так далее. Беккер быстро проделал это со всеми буквами.
Он взорвался: - Сьюзан, выслушай. Я вызвал тебя сюда, потому что мне нужен союзник, а не следователь. Сегодня у меня было ужасное утро.
