... e of Hermetic theory and the consciousness in the alchemical mind that what might with success be applied to nature could also be applied to man with similar results. Says Mr. Waite, "The gold of the philosopher is not a metal, on the other hand, man is a being who possesses within himself the seeds of a perfection which he has never realized, and that he therefore corresponds to those metals which the Hermetic theory supposes to be capable of developing the latent possibilities in the subject man." At the same time, it must be admitted that the cryptic character of alchemical language was probably occasioned by a fear on the part of the alchemical mystic that he might lay himself open t ...

Austria is predominantly a mountainous country, with an average elevation of about 3000 feet. Most of the land falls within the eastern part of the Alps. In general the major mountain ranges of Austria run in an eastern-western direction and are separated from one another by large valleys. The northernmost line of ranges includes the North Tirol Alps and the Salzburg Alps. Among the central range is the Hohe Tauern, which tops in the Grossglockner, the highest elevation in the country. The Pasterze Glacier, one of ...

- Chemical Reactions - 1,932 words
Chemical Reactions Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the air from all substances during combustion. He explained that a burning candle would go out if a candle snuffer was put over it because the air inside the snuffer became saturated with phlogiston. According to his ideas, wood is ...

- Diamond - 1,187 words
Diamond The unique nature of diamond is heavily dependent upon its composition, crystal structure, and mechanical, thermal, and electromagnetic properties.1 Of those dependencies, composition exacts the most influence over the characteristics. Crystal structure is the repeating pattern of diamonds composition, and each of the properties are the result of molecular interaction which is determined by composition. Therefore, composition is paramount in the determination of the qualities of diamond. Before its discovery, adamantane was known as decaterpene, the name applied by Decker to his tricyclic hydrocarbon. Decker believed that his decaterpene was similar in structure as the diamond lattic ...

Environmental Hazards Which Effect Pregnacy Environmental Hazards That Effect Pregnancy Did you know that 30 to 80 percent of all conceptions end in miscarriages, stillbirth or early infant death? And that mens sperm counts have gone down by 40 percent during the last thirty years? There are many reasons that these things happen. Most of these factors to a healthy birth have to do with the environment. Some examples include radiation, viruses, drugs and chemicals. These are the cause of 5 to 11 percent to birth defects and can cause miscarriages. Toxic substances come in many forms. You should know the different forms to look out for. There are hazardous vapors such as the fumes that come fr ...

It Technology 1.0 INTRODUCTION A quote from a PC World magazine on "The Digital Future" said, "in the future, people will live twice as long, computers will die twice as fast" 1. As computer technology continues to accelerate at an unprecedented rate, information technology (IT) equipment waste is becoming an increasingly significant portion of the solid waste stream. Information Technology equipment waste is receiving increased attention for the following reasons: Rapid advances in technology result in IT equipment becoming obsolete at an increasingly rapid pace. This is resulting in an increase in the rate and quantity of IT equipment entering the waste stream; A piece of IT equipment wa ...

- Place In Periodic Table - 1,300 words
Place In Periodic Table Phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi) form a group of four elements in Group 5A of the periodic table. They exhibit increasing metallic properties going down the group. Nitrogen (N), which heads the group, is a colorless, odorless, and tasteless gas. Phosphorus is a highly reactive nonmetal, arsenic and antimony are poisonous metalloids, and bismuth is a true metal. Because of the arrangement of the outer electrons in their atoms, each of these elements can form up to five chemical bonds with other elements or groups of elements. Arsenic has an atomic number 33, atomic mass is 74.9216, and it sublimes (passes directly into a vapor without melti ...

- Platinum - 866 words
Platinum I am a silvery metal that is as resistant to corrosion and tarnishing as gold. I am almost as rare and consequently am the likewise highly valued and used in Jewelry. I am also used in chemicals industry as a catalyst, in medicine as an anti-cancer drug, and in catalytic converters for car exhausts. I have an atomic number ok 78, my atomic weight is 195.09 (when rounded 195) and a symbol of Pt. Who am I? Im platinum of coarse! Platinum is a member of the six transition elements in Group VIII of the periodic table known collectively as the platinum metals (ruthenium, rhodium, palladium, osmium, iridium, and platinum). The name is derived from the Spanish platina, meaning, silver. The ...

- Printing Press History - 574 words
Printing Press History In the early 1450's rapid cultural change in Europe fueled a growing need for the rapid and cheap production of written documents. Johannes Gutenberg, a goldsmith and businessman from the mining town of Mainz in southern Germany, borrowed money to develop a technology that could address this serious economic bottleneck. Gutenberg foresaw enormous profit-making potential for a printing press that used movable metal type. Gutenberg developed his press by combining features of existing technologies: textile, papermaking and wine presses. Perhaps his most significant innovation, however, was the efficient molding and casting of movable metal type. Each letter was carved in ...

- Science Alchemy Alchemy, Ancient Art Practiced Especially In The Middle Ages, Devoted Chiefly To Discovering A Substance That - 850 words
Science Alchemy Alchemy, ancient art practiced especially in the Middle Ages, devoted chiefly to discovering a substance that would transmute the more common metals into gold or silver and to finding a means of indefinitely prolonging human life. Although its purposes and techniques were dubious and often illusory, alchemy was in many ways the predecessor of modern science, especially the science of chemistry. The birthplace of alchemy was ancient Egypt, where, in Alexandria, it began to flourish in the Hellenistic period; simultaneously, a school of alchemy was developing in China. The writings of some of the early Greek philosophers might be considered to contain the first chemical theorie ...

- Silicon Microchips - 1,443 words
Silicon Microchips Silicon is the raw material most often used in integrated circuit (IC) fabrication. It is the second most abundant substance on the earth. It is extracted from rocks and common beach sand and put through an exhaustive purification process. In this form, silicon is the purist industrial substance that man produces, with impurities comprising less than one part in a billion. That is the equivalent of one tennis ball in a string of golf balls stretching from the earth to the moon. Semiconductors are usually materials which have energy-band gaps smaller than 2eV. An important property of semiconductors is the ability to change their resistivity over several orders of magnitude ...

The Republic Of South Africafrica The Republic of South Africa By John Wendell September 27, 2000 The Republic of South Africa has had an interesting history. The country gained its independence from Great Britain on May 10, 1910. At that time the country was a struggling agricultural nation, and now it is a semi-industrialized nation. South Africa is slightly less than twice the size of Texas and has a population of 43,421,021 person, With about 15 million economically active in the work force, the unemployment rate is about 30%. The country started of as predominately agricultural with 1,219,912 sq. km of land. They use 67% of the land as pastures, 10% is arable land, 1% is crops, and 7% i ...
