Unification of theories

Stage 3 The scientific or positive age. The unification of theory and practice, which is the result of a combination of rational thinking and observation, allows us to recognize relationships and similarities. Ideally it is possible to describe many single phenomena on the basis of one unified postulate, i.e., to formulate a scientific law. 

The Kona Conference and many other events that I could cite show that it is now time to end this compartmentalization of knowledge, get our act together, and understand that there is a common body of concepts and techniques that apply to a large domain of very important processes and situations. Professor Doraiswami Ramkrishna has made a major contribution to the needed unification of theory and computational techniques of population balances with the preparation of his book Population Balances Theory and Applications to Particulate Systems in Engineering. It should be, and I hope it will be, the source that workers from many diverse fields turn to when they seek to learn the concepts and techniques of population balance modeling of particulate systems. 

We present a molecular theory of hydration that now makes possible a unification of these diverse views of the role of water in protein stabilization. The central element in our development is the potential distribution theorem. We discuss both its physical basis and statistical thermodynamic framework with applications to protein solution thermodynamics and protein folding in mind. To this end, we also derive an extension of the potential distribution theorem, the quasi-chemical theory, and propose its implementation to the hydration of folded and unfolded proteins. Our perspective and current optimism are justified by the understanding we have gained from successful applications of the potential distribution theorem to the hydration of simple solutes. A few examples are given to illustrate this point. 

Standard Model The model for the formation of the Universe and the unification of forces - the current, flawed theory of everything. 

Dalton presented his atomic theory in his bookyl New System of Chemical Philosophy, the first and crucial part of which was published in 1808. His pictures of atoms and molecules provide a unification of the micro-world and the macro-world of chemistry they show at once what we can observe (for example, hydrogen and oxygen combining to make water) and what we cannot the union of real, tangible atoms. Historian of chemistry William Brock says that Dalton s symbols encouraged people to acquire a faith in the reality of chemical atoms and enabled chemists to visualize relatively complex chemical reactions. .. Between them, Lavoisier and Dalton completed a revolution in the language of chemistry. ... 

We note that Sachs epochal unification of general relativity and electrodynamics [27] does cover the quarks and gluons causally, as well as fermions and bosons. We point out that curvature of spacetime involves both positive and negative curvatures—with time involved as well as space. Certainly the theory is compatible with the consideration of time as a special form of EM energy. 

Hence the first unification of relativity and quantum theory originated from the combination of Eqs, (1) and (3) in the form...

Energy-momentum conservation is expressed by dvT = 0 for a closed system. If Tfi were a symmetric tensor (when converted to 7 /x"), this would be assured because i f Tfi = 0 by construction. Since the gauge field part of the tensor deduced from Noether s theorem is not symmetric, this requires special consideration, as discussed below. A symmetric energy-momentum tensor is required for any eventual unification of quantum field theory and general relativity [422], The fermion field energy and momentum are... 

Einstein granted that the (Dirac) equation was "the most logically perfect presentation" of quantum mechanics yet found, but not that it got us any closer to the "secret of the Old One". It neither described the real world phenomena that he wanted to understand nor proposed new concepts that would make the real world accessible to understanding. Furthermore, Dirac s unification of quantum mechanics with special theory of relativity left out Einstein s later success with general relativity and the gravitational field. 

Hence, the further development of quantitative copolymerization theory, as it ensues from the above-mentioned unsolved problems, is connected with the consideration of physical factors, along with chemical ones, which have a direct influence on process rate and statistical characteristics of the forming products. The future success in such a direction will be connected obviously with the unification of the ideas of chemical copolymerization theory, presented in this review, with the modern concepts of statistical physics both of macromolecules and copolymer solutions. 

Chemistry is a great and complex subject, and an engrossing one. It has two aspects descriptive chemistry, the discovery, tabulation, and correlation of chemical facts and theoretical chemistry, the formulation of theories that, upon verification, unif) these facts and combine them into a system. Both of these aspects are presented, side by side, in this book. 

There is merit in the view that forces and entropy are important. There is merit in the view that geometry is a determining factor in self-assembly. But there have been few attempts at model self-assembly problems which embrace both views. The aim of this paper is to develop a simple theory dealing with one area of self-assembly, the spontaneous aggregation of one-component lipid suspensions, where the fusion of both notions results in a unification of a multiplicity of diverse observations.
