An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
In 1951, the first 24 Statements on Auditing Procedure were codified [6] The Codification also contains a summary history of the process of standardizing auditing practice up to 1951 (see pp. 5–8). In 1954, the Committee on Auditing Procedure finished work on the booklet Generally Accepted Auditing Standards: Their Significance and Scope. [7]
Materiality in governmental auditing is different from materiality in private sector auditing for several reasons. Most importantly, due to the format of state and local government financial statements under GAAP , the AICPA Audit Guide for State and Local Governments requires auditors to consider materiality by "opinion unit" rather than for ...
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

Statistical process control is appropriate to support any repetitive process, and has been implemented in many settings where for example ISO 9000 quality management systems are used, including financial auditing and accounting, IT operations, health care processes, and clerical processes such as loan arrangement and administration, customer ...
The Eyring equation (occasionally also known as Eyring–Polanyi equation) is an equation used in chemical kinetics to describe changes in the rate of a chemical reaction against temperature. It was developed almost simultaneously in 1935 by Henry Eyring , Meredith Gwynne Evans and Michael Polanyi .
The history of such philosophical theories that relate to chemistry can probably be traced back to every single ancient civilization. The common aspect in all these theories was the attempt to identify a small number of primary classical elements that make up all the various substances in nature.
