Sulfur Hexafluoride, the Anti-Helium

Sulfur Hexafluoride, the Anti-Helium Sulfur hexafluoride is a non-toxic, invisible gas that you can use to perform interesting chemistry demonstrations. Breathe it in and make your voice much deeper when you talk. Pour it into a container and float an airplane or a ship on nothing. In a way, it is like the anti-helium gas, because while helium is about six times lighter than air, sulfur hexafluoride is six times heavier. Sulfur Hexafluoride Facts Inorganic compound with a chemical formula SF6Non-polar gasNon-toxic, odorless, colorlessnNn-flammable at room temperature and pressureOctahedral geometryPoorly soluble in water; soluble in nonpolar organic solventsDensity of 6.13 g/L at sea level Fun Things to Try with Sulfur Hexafluoride Float Your Boat: Pour sulfur hexafluoride into an aquarium or large beaker. It is heavier than air, so it will sink. You can float light objects on the invisible gas, such as a paper airplane or a boat made from aluminum foil. If you use a cup to scoop up some of the sulfur hexafluoride and dump it into a foil boat, you can sink it.Talk or Sing with a Deep Voice: Sulfur hexafluoride is denser than air, so sound travels through it more slowly. If you breathe in a lungful of sulfur hexafluoride, your voice will become much deeper. Even though sulfur hexafluoride is non-toxic, you need to use care when performing this demonstration to avoid hypoxia and fainting (the same caution applies to helium). Dont breathe the gas for prolonged periods of time. Where You Can Get Sulfur Hexafluoride Sulfur hexafluoride is a specialty gas, used in medicine for eye surgery and ultrasound imaging; in industry as a tracer gas, dielectric, and as an etchant; and mixed with argon as an insulator between layers of windows. It has enough uses that you may be able to find it at a store that sells specialty gasses (try the yellow pages), such as oxygen, argon, and nitrogen.

Pyrrhic Victory - Origin of the Term

Pyrrhic Victory - Origin of the Term A Pyrrhic victory is a type of win that actually inflicts so much destruction on the victorious side that it is basically tantamount to defeat. A side that wins a Pyrrhic victory is considered ultimately victorious, but the tolls suffered, and the future impact those tolls, work to negate the feeling of actual achievement. This is sometimes referred to as a ‘hollow victory’. Examples: For instance, in the world of sports, if team A defeats team B in a regular season game, but team A loses its best player to a season-ending injury during the game, that would be considered a Pyrrhic victory. Team A won the current contest, however losing their best player for the remainder of the season would take away from any actual feeling of accomplishment or achievement that the team would typically feel after a victory. Another example could be drawn from the battlefield. If side A defeats side B in a particular battle, but loses a high number of its forces in the battle, that would be considered a Pyrrhic victory. Yes, side A won the particular battle, but the casualties suffered will have severe negative effects from Side A going forward, detracting from the overall feeling of victory. This situation is commonly referred to as â€Å"winning the battle but losing the war.† Origin The phrase Pyrrhic victory originates from King Pyrrhus of Epirus, who in 281 B.C., suffered the original Pyrrhic victory. King Pyrrhus landed on the southern Italian shore with twenty elephants and 25,000-30,000 soldiers ready to defend their fellow Greek speakers (in Tarentum of Magna Graecia) against advancing Roman domination. Pyrrhus won the first two battles that he participated in upon arrival on the southern Italian shore (at Heraclea in 280 BC and at Asculum in 279 BC). However, throughout the course of those two battles, he lost a very high number of his soldiers. With his numbers cut drastically, King Pyrrhus’s army became too thin to last, and they eventually ended up losing the war. In both of his victories over the Romans, the Roman side suffered more casualties than Pyrrhus’ side did. But, the Romans also had a much larger army to work with, and thus their casualties meant less to them than Pyrrhus’s did to his side. The term Pyrrhic victory comes from these devastating battles. Greek historian Plutarch described King Pyrrhus’s victory over the Romans in his Life of Pyrrhus: â€Å"The armies separated; and, it is said, Pyrrhus replied to one that gave him joy of his victory that one other such victory would utterly undo him. For he had lost a great part of the forces he brought with him, and almost all his particular friends and principal commanders; there were no others there to make recruits, and he found the confederates in Italy backward. On the other hand, as from a fountain continually flowing out of the city, the Roman camp was quickly and plentifully filled up with fresh men, not at all abating in courage for the loss they sustained, but even from their very anger gaining new force and resolution to go on with the war.†

Parties and Democracy in the Eastern European Countries Essay

Parties and Democracy in the Eastern European Countries - Essay Example Parties help fix the newly established democratic governments in a broader community and influence their stability among the numerous processes of quick social and industrial change. Valuable constitutions and the various processes implicated in the rule of law are reinforced by the possibilities parties put forward for the progress of a more active citizenry and the appearance of a strong democratic political way of life. "There are also strong reasons to believe such conditions are conducive to stable processes of economic development and the formation of effective market economies" (ibid, p.2). The concentration on electoral activity and the methods parties use to reach administration office are particularly important. To the extent of post-communist eastern Europe, it can be stated that involvement in competitive elections is a foremost attribute of party identity development and the advancement of such organizations. Party competition is an important characteristic of the contemporary governments that differentiates them from the single party totalitarianism of the communist era and offers at the present moment a real focus of attention. The single-party government that existed within the Soviet dictatorship, and afterwards reached other parts of Europe and the world, had nothing in common with the experience of the democratic competitive party regime. Modern Eastern Europe contains most of the post-communist countries and the main part of former the Soviet Union. Lewis gives the following classification of eastern European countries: "east-central Europe: Hungary, Poland, Slovakia, Slovenia and the Czech Republic; the Baltic states: Estonia, Latvia and Lithuania; the Balkans: Romania, Bulgaria, Albania and the most of the former Yugoslavia (Bosnia, Croatia, Macedonia, Montenegro and Serbia) former Soviet republics: Belarus, Moldova and Ukraine" (ibid, p.5). 1989 was an important year both for the states of eastern Europe and the growth of a democratic Europe in general. Its most outstanding image can be seen in opening wide of the strongly protected gates set in the Berlin Wall and the enthusiasm with which the inhabitants of Berlin set about its destruction, but consequently it was a process of creation that would do most to resolve how long and in which form this recently received liberty would exist. This probably influenced Velvet revolution in the Baltic states with final fall of the Soviet empire. The main part of the process was the construction of new political organizations and the establishment of a variety of parties competent in expressing the viewpoints and objectives of contemporary population. On the other hand, there was a serious problem faced by the number of post-communist countries - the lack of experience of liberal democracy and the comparative limitation of party development after the countries had gained independ ence. The building of civil society as the main focus of political interest has succeeded during the recent years, since general civil liberties, gained by people, have influenced their outlook and political viewpoints. This is the main characteristic of 'subunits, capable of opposing and countervailing the state' (Gellner, 1991, p.500).
