- 191: Nuclear Fusion
- ... to use several more times just because it is so cool. In a thermonuclear reaction matter is forced to exist in only in a plasma state, consisting of electrons, positive ions and very few neutral atoms. Fusion reactions that occur within a plasma serve to heat it further, because the portion of the reaction product is transferred to the bulk of the plasma through collisions. In the deuterium- tritium reaction the ...
- 192: The Fear of Science
- ... of the evolution of man because it went against their religion, which believed that God created the world. Science, soon, developed the big bang theory, which states that earth was created by the attraction of atoms. The nineteenth century society was afraid of science because it contradicted their beliefs, and was afraid that the results of science would lead to the destruction of mankind. Thus, the study of science was limited ...
- 193: Alcohol 2
- A class is chemical compounds, all if which consists of chemically bonded atoms of carbon, hydrogen, and oxygen all alcohol molecules contain at least one hydroxyl group. When people say alcohol they usually think of beer, wine, or liquor, but there are several types of alcohol. An alcoholic ...
- 194: The History of Phamaceutical Compounding
- ... this theory and came up with the idea of the four elements that composed the earth: earth, water, air, and fire. With this scientific break through, others like Democritus thought these elements were composed of atoms with minute particles moving in a vacuum. Aristotle believed that the elements formed a continuum of mass and therefore a vacuum could not exist. Slowly, the atomic idea was lost by the Greeks, but it ...
- 195: The Discovery Of The Electron
- ... that is, a current, about the electron axis; but a classical analog to this moment has much less meaning than that to the orbital magnetic dipole moment. The magnetic moments of the electrons in the atoms that make up a solid give rise to the bulk magnetism of the solid.
- 196: Alternate Energy Sources
- ... about this new energy source so we can use it to power the future. Fusion Power Fusion Power is probably the biggest known Alternate Energy Resource. Fusion is the joining of the nuclei of two atoms to form the nucleus of a heavier element. It occurs mostly with hydrogen and other light elements. Fusion reactions, also called thermonuclear reactions, release a great deal of energy. Scientists are still conducting experiments on ...
- 197: A Chemist
- ... subfields some of these are analytical chemistry, organic chemistry, and physical chemistry. Analytical chemists ascertain the nature, structure, and composition of a substance. Organic chemistry involves orgainc substances. Aphysical chemist, however, studies the attributes of atoms and molecules. Also they study why and how chemical reactions occur (Choices). After researching this career thoroughly I have concluded that this occupation, even though it is not my first choice, would be a good ...
- 198: Derek
- ... floor. He could hear the clank and clatter of dishes from the dishroom, and the slamming of doors and calling of orders as the waiters and waitresses bounced off of and around each other like atoms in a solution. He realized he had to go back out there and face that frantic pace again in only fifteen minutes. Unconsciously he looked at his watch and saw that five of those minutes ...
- 199: Arsenic
- ... 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 ...
- 200: Comets
- ... and tiny fragments of stony and metallic meteoric material. Some comets, the larger ones, have a nucleus of 10 kilometers (Schweighauser 22). The second feature of comets is the coma. The coma is composed of atoms and molecules of gas that travels with the nucleus. The coma may be up to 100,000 kilometers in diameter. The third feature of a comet is the head. The head is just the name ...
