Galileo and Aristotle on falling bodies 29 November Alchemy can be defined as a science practiced in the early and Middle Ages with the aim or transforming ordinary metals into gold. It was based on a complex view where by everything is believed to contain a universal spirit. Metals were believed to grow inside the earth, when a base metal was found, it was thought to be spiritually immature form of higher metals. Alchemy was based on the misunderstanding of basic chemistry and physics.

From the first sight it seems that the book is just a continuation of long-lasting debate about the false facts of American history pupils are taught in school. However, close reading makes it clear that Loewen’s approach to problem in teaching American history is unique. While other critics of teaching methods and modern textbooks talk about false information, Loewen states that American history is not only full of false facts, but uninteresting (Loewen, 1995).

By this phenomenon, a majority of proteins, likemany other molecules in the body, exist in two forms as mirror images of each other. However, within the body, these molecules exist in one chiral form although they could be present in both forms, and reason for such an existence has been explored for a long time.

Iron is found in different concentrations at\round the world. It constitutes about 5 percent of the earths crust. However, iron alone is not useful; it is not hard enough to be molded into shapes. In addition, iron is too weak to carry weights. To ensure its usage in the manufacture of goods, iron must be alloyed with other minerals. Carbon is the best and readily avail able element that is alloyed with iron. Carbon is found in large quantities from wood and coal (Hall, 1997).

An exothermic reaction (usually, hydration of metal salts in water) provides the heat energy required. In the cup, the reactants are placed in separate compartments. A trigger on the cup allows you to heat the contents of the cup when required. On press of the trigger, the wall separating the reagents punctures and water reacts with the reagent to generate heat.
