Chemistry is a science. This means that attempts to organize the information collected in a system of knowledge. Its object of study is the matter and its transformations, though it differs from the scale physics in which you work: the basic unit of best general chemistry book is the molecule (which are included monatomic molecules and giant molecules such as polymers). The parts of the atom (protons, neutrons and electrons) are of interest as they serve to understand the chemical transformations. The atomic structure remains as a topic of interest to physicists. The chemical then studied everything about the transformations of the molecules, their energies, velocities, detailed descriptions of each step in the transformation of one molecule into another. The chemical is not stopped in the molecule, has recently emerged systems chemistry, which studies the interactions of molecules to form structures, as in the case of the fat molecules that are grouped inside the cell wall. The chemistry is primarily an experimental science. This means that the vast majority of chemical have been obtained from carefully controlled observations and measurements (empirically). Like all human activities, chemistry is capable of being used for good or for ill. Chemical is the responsibility of evaluating the effect that their work will have on other people, either directly as in the case of a new drug, or indirectly, by affecting the environment for example. These considerations are more important when we see the enormous economic importance of chemistry. . .
While most eyes are now turned to the new information technology and communication (NTIC), there are growth sectors that continue to thrive in the shadow of the technological monster, and who demonstrate a real economic strength. Chemistry is one of them . . . . Appeared in the nineteenth century during the second phase of the industrial revolution, the chemical industry is in constant development since. Some scientists, such as Claude Louis Berthollet, who discovered the virtues of chlorine bleaching, are powerful symbols of the industry today must. If the chemical sector grew over time, is because it benefits from the technological advances that attract so much attention. Each year, investments in equipment, products, and other ingredients involved in various experimental protocols are considerable, and fueling the momentum of the chemical industry, dependent on research. Chemistry is a particularly active in the pharmaceutical field because, as you know, modern societies can not live without drugs and other chemicals that are of health. According to this, there is naturally a certain force employment in pharmaceutical research, or simply the use of pharmacist. Employment in research is vital because, as we noted above, it is the engine of the chemical industry. Without research, there is no invention, without invention, there is no product or process innovation, without products or innovative processes, there is no progress, and the industry would eventually collapse on its own foundations. As for employment as a pharmacist, it meets a need corresponding to changes in hygiene and health. For if the drugs are proliferating at the same rate as bacteria and other infections, it is always more specialists able to make the connection between all these treatments and people . . . . . .
