Alpha in Chemistry
Alpha in ChemistryAlpha in chemistry refers to the concept of measurement, both in the natural and human sciences. According to the eminent American scientist Charles Hartshorne, 'a single measure is not a single degree of change,' as in physics, or 'all the true measures are not degrees of freedom.' The quantum physicist Hermann Weyl said, 'There are only two forms of the science of measurement: it must either be an indirect measure, if measured by itself.' So, then the measurement is the absence of an object, which must also be defined by another, and then measured.The word 'measurement' comes from Latin, from 'mettere', which means to put or to set. The Latin measurere means to set. This means that the measuring instrument, the person, the procedure, and the body part or substance used in measuring are all equally important. This applies also to the quantitative method, which can either be quantitative or qualitative.The notion of the quantitative aspect of chemistry dates back to the 17th century, when Sir Humphry Davy, the distinguished scientist, devised his theory that molecules exist in pairs, that is, identical in chemical relationship, and that they take on the roles they fulfill only as a result of the interaction they engage in with each other. He also advanced the idea that gases can be broken down into simpler substances, such as solids and liquids. He realized that acids and bases were compounds of hydrogen atoms and non-polar molecules, and thus that only the atom of hydrogen was the same with the corresponding atom of a polar molecule. The ionic compound, which consisted of one electronegative atom, was his next step. He hypothesized that oppositely charged atoms should remain in contact with each other.However, in modern chemistry, this concept of quantitative chemistry is merely recognized. This branch of chemistry does not have a formal methodology for determining exact quantities. Most, if not all, measurements are only based on random gues swork, assuming only that there are a good number of steps taken. All that is required is for the chemist to rely on intuition and compare how one thing differs from another.There is one exception, though. According to the famous Russian chemist Ignatius Mukwege, a quantitatively defined method is required for precision work. On this basis, the techniques used for measuring are called 'quantitative', or 'proportional', and they are used to quantify the quantities and their variations.In Chemistry, it is not enough to determine the degree of or quantity of a substance, but one must also calculate its rate of change, or 'change of variation', and compare this with a standard. This requires a corresponding calculation, which is called the 'standard-area formula'. On this basis, a particular amount of some substance must be equated with the same quantity of another substance having the same physical nature.It is not necessary to use an actual specimen, as such, in chemical analysis. For example, one can have a material dissolved in water and trace the biological waste through the residue. A specific ratio of biological waste to biological sample can be calculated using the standard-area formula. It is not too difficult, however, to establish 'measurements' on biological samples, and determine the quantity of waste present in them.Alpha also refers to qualitative properties of matter. Such properties may be physical properties, such as the temperature at which an element melts, or the physical nature of the element, as it is. Or, these properties may be properties of molecules.
