PRESENTATION OUTLINE
Neils Bohr background- Niels Henrik David Bohr was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.

Bohr's experimental design-Bohr's theory that electrons existed in set orbits around the nucleus was the key to the periodic repetition of properties of the elements. The shells in which electrons orbit have different quantum numbers and hold only certain numbers of electrons -- the first shell holds no more than 2, the second shell up to 8, the third 10, the fourth 14. Atoms with less than the maximum number in their outer shells are less stable than those with "full" outer shells. Elements that have the same number of electrons in their outermost shells appear in the same column in the periodic table of elements and tend to have similar chemical properties.
Procedures involved in the expirement- The advancement of science depends in general on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigor while giving little weight to experiments and observations. For example, while developing special relativity, Albert Einstein was concerned with the Lorentz transformation which left Maxwell's equations invariant, but was apparently uninterested in the Michelson–Morley experiment on Earth's drift through a luminiferous ether. On the other hand, Einstein was awarded the Nobel Prize for explaining the photoelectric effect, previously an experimental result lacking a theoretical formulation. Which was invented by Bohr .
Collected data- The influence of Niels Bohr's work, of his approach to research, both practical and theoretical, is widely felt today. His contributions to our knowledge of the atomic constituents of matter and to our view of science, remain of fundamental importance.The publications of his collected works will give historians of science and scientists easy access to a life-work entirely devoted to the rational analysis of the laws of nature and of the singular character of their meaning for us.In addition to Bohr's published papers, the series includes unpublished manuscripts and a wide selection of letters and other documents, with explanatory notes.
Conclusion- Less of a household name than colleagues such as Albert Einstein, Niels Bohr nevertheless contributed immensely to the developments of twentieth-century physics. Building on the work of his mentor Ernest Rutherford, Bohr developed his own atomic model that clarified and expanded the field of quantum theory. This and other contributions mark him as one of the century's most distinguished scientists, whose work has fundamentally changed and influenced our understanding of physical reality.
