An alternative way to estimate tmeness is to analyze a series of test samples by the method based on the developed sensor and by another method (preferably a reference/validated method) based on different physical/chemical principles. This because it is quite unlikely that the second method can suffer from the same systematic errors. Method comparison must be performed by specific regression techniques since, in its case, assumption (1) of the OLS method is not valid anymore both variables are affected by experimental errors (see Sect. 18.2.1) and Model II regression methods are mandatory. The relevant literature information is unexpectedly plentiful, since disciplines interested in such a kind of comparison span from statistics to astronomy, geology, physics, chemistry, biology, allometry, industrial pharmacology, and medicine (references (2i-23) (4S-50) ...

The first listing of the elements is generally attributed to Lavoisier in 1789. Of the twenty elements listed, the discovery of five was the result of research conducted by Stheelc of Golltenberg. With the development of nuclear physics and the application of these principles to astronomy and cosmology, in recent years the chemical elements have been viewed from new vantage points with much concentration on physical and nuclear characteristics as well as chemical properties. 

Due to element formation in stars, the abundances of the isotopes in our Galaxy have evolved over time. While study of this evolution can be an excellent classroom activity for illustrating principles of chemistry, astronomy, and nuclear physics, it requires a number of complicated ingredients. We are developing some online tools for investigating these inputs and for demonstrating the chemical evolution of the Galaxy. We recommend that persons interested in these tools subscribe visit www.webnucleo.org for more information. 

About every other year from 1900 onward there was a question about the work of one or two eighteenth- or nineteenth-century chemists such as Cavendish, Lavoisier, Dalton, Davy, and Faraday. Other historical questions included Describe, and explain, the principle of the spectroscope. How has this led to the discovery of new elements and to a knowledge of the sun and stars , which links astronomy with the discovery of the periodic system. Another question, from 1918, was, In what respect has the discovery of radioactivity modified our conception of the chemical atom There were, however, only a few historical/philosophical questions, with most questions being more factual, such as, How does ammonia react with chlorine, mercuric chloride, potassium, ethyl iodide, ethyl oxalate ...
