Estimation Theory
A parameter space can be defined as a group of values of parameters which we can obtain in a particular situation or problem. Often the parameters become the inputs of a function, in which the parameter space becomes the domain of the function . In statistics, Parameter spaces are generally u..
Arrhenius Theory
In 1884 the Swedish chemist Svante August Arrhenius (1859-1927) proposed that acids and bases be defined in terms of the chemical species they form when they dissolve in water. An Arrhenius acid is a hydrogen containing compound that, in water produces hydrogen ions (..

The presence of halogens in any organic compound is detected by using sodium extract (Lassaigne's extract) with silver nitrate as follow..
Quantum Theory
In 1928, P.A.M. Dirac made a bridge between quantum theory and relativity by his linear wave equation of the electron. Previously there had been three principle stages of progress, namely Einstein's special theory ( 1905), his general theory ( 1915), and Weyl,s ..
VSEPR Theory
The VSEPR theory, proposed by R.J.Gillespie and R.S. Nyholmm in 1957, is based on the repulsions between the electron-pairs in the valence-shell of the atoms in the molecule. According to VSEPR Theory Definition, it was developed to predict the shapes of the molecules in which..
Werner's Theory
Introduction : The evolution of today's atomic structure took nearly 40 to 50 years to finish. There were many milestones, like discovery of sub-atomic particles,finding out the charge on them, etc. Among them is the inclusion of Quantum mechanics. This provided a clear concept for the wave nat..
Theories of Ageing
Many theories have been proposed to explain the process of ageing. Many theories have been proposed to explain the process of ageing. The important ones have been listed. The theories of Ageing have been grouped into two categorie..

Theory of Magnetism
A completely satisfactory theory of magnetism has still not been formulated. At present it is assumed that magnetism is due to the movement of the electrons. The electrons circulate around the nucleus of the atom. A completely satisfactory theory of magnetism has still no..
