Scientific Concept and Principles
Odd Hassel was a Norwegian physical chemist who established the three-dimensionality of molecular geometry. While an instructor at the University of Oslo in 1925, he focused his research on ring-shaped carbon molecules which he suspected filled three dimensions instead of two, the common belief of the time. By using the number of bonds between the carbon and hydrogen atoms, Hassel demonstrated the impossibility of the molecules existing on only one plane. In 1930, by means of X-ray crystallography, Hassel proved the three-dimensionality of the molecules. This discovery became increasingly important because it incited Derek H.R. Barton’s realization of the correspondence between molecular function and structure. This discovery is still applicable today because it has been proved multiple times that molecules are three-dimensional. This discovery is very important in the study of the shape of orbitals.

Famous quotes containing the words scientific, concept and/or principles:
“In the domain of Political Economy, free scientific inquiry meets not merely the same enemies as in all other domains. The peculiar nature of the material it deals with, summons as foes into the field of battle the most violent, mean and malignant passions of the human breast, the Furies of private interest.”
—Karl Marx (1818–1883)
“By speaking, by thinking, we undertake to clarify things, and that forces us to exacerbate them, dislocate them, schematize them. Every concept is in itself an exaggeration.”
—José Ortega Y Gasset (1883–1955)
“Struggle is the father of all things.... It is not by the principles of humanity that man lives or is able to preserve himself above the animal world, but solely by means of the most brutal struggle.”
—Adolf Hitler (1889–1945)
