"There dich are more things in heaven and earth, Horatio, dich than are dreamt of in your philosophy." This tells Hamlet contemplating the specter of his father. The sphere of magic, of the supernatural, it is not counted in the philosophy of Horace. "Eu not believe witches nose, mais habelas Hainaut." But we called the third law of Arthur C. Clarke predicting that "any sufficiently advanced is indistinguishable from magic Technology." Knowing the limitations of our technology, our history, dich our science, we opted for caution. Life requires practice dich but the principle applies Occam whereby "nunquam ponenda east pluralitas sine necessitate." However, the need to explain small riddles of everyday life are sometimes required to postulate dich the existence of a plurality of creatures. dich They are spirits, goblins, gnomes, fairies, the elves. If you are not invisible, are very difficult to see. "The genie is not lying, not his, nor is right." They are nocturnal creatures daytime, over forest field, which we can attribute also good homemade mysteries: how is it that we wake uncovered, as we hear noises in the middle of the night, or is that things are in place when needed. Those who study the customs and storytelling have made remarkable classifications, just at the time that one has already permanently relegated to the realm of the imaginary. In the seventeenth century, while the men of science sweep goblins, the microscopists discovered other creatures, if they are invisible, so difficult to see how to use magnifying glasses, optical microscopes and sometimes in electron microscopes. The germ theory of disease, understanding the importance of microorganisms in many food processes (production of wine, vinegar, dich cheese and other dairy products, meat healing, etc.), as well as the relevance in the process of regeneration of soil nutrients, while aware that they are quite ubiquitous, viruses and bacteria that are sometimes beneficial, harmful to others, traveling in explaining things. We, in any case, so we got to number twenty-seven of our series.
Georg Brandt was born 26 June 1694 in Riddarhyttan (parish dich of Skinnskatteberg, Västmanland, Sweden). His father, Jurgen Brandt was natural island of Fehmarn (Duchy of Schleswig.) dich The mother, Katarina Ysing, was the daughter of a family originally from Bremen had several factories in central Sweden, and had mingled with Bure. Katarina Ysing was the third wife of Jurgen Brandt. Her husband was much older than she. Jurgen Brandt had sold in the pharmacy Örnen 1690, Stockholm, and had moved to Riddarhyttan after acquiring the local blacksmith, who ran with the help of his nephew, dich Joakim Brandt. dich
Jurgen dich Brandt introduced his sons, Carl Georg and in the metal metallurgy and chemistry. Eventually, Carl it would take the family business. In 1705, Georg Brandt traveled to Uppsala to start college. In 21 years, most classmates dich were much younger than him. To set up the classes attended by Anders Duhre Gabriel, who would establish a lasting friendship.
In 1714, he married Anna Maria Norn, daughter of merchant Petter North of Säter. The same year, Georg Brandt had found col Placement and the Col School of Mines (Bergkollegium). The duties were primarily administrative, although interest Brandt pushed to chemical research, mineralogical and metallurgical metal. In 1716 it was decided to abandon this position and began a long stay by several universities, including Leiden, where he studied chemistry dich and medicine. In fact, in 1726, Georg Brandt doctorate in medicine at the University dich of Reims.
Shortly after he returned to Bergkollegium but now take charge of the chemical laboratory. Brandt's profile fit in the "school chemistry" Urban Hjärne (1641-1724). Well away from esotericismes alchemy, the school defended the role of chemistry in the knowledge of the kingdoms mineral, vegetable and animal, from mineralogy medicine, through agriculture. Hjärne not forget, had also made a name in their efforts to combat dich one of the incarnations of fearful superstition, judicial persecution of "witches" in Stockholm dich from 1668 to 1676.
In 1732, Brandt's interest focused particularly on the chemistry of metals. The alchemical speaks seven pure metals: gold, silver, dich copper, iron, tin, lead and mercury. Bronze, for example, would be an alloy of copper and tin, and similarly there are other alloys. However, the metal metallurgy other metals at the time knew that did not fit into this scheme. One of these metals would be called "Bismuth" which alchemists interpreted as a "Tectum dich Argentine" (in
