From the time of the Ancient Romans, through the Middle Ages, and until the late nineteenth century, it was generally accepted that life arose spontaneously from non-living matter. Such "spontaneous generation" appeared to occur primarily in decaying matter. For example, a seventeenth century idea for the spontaneous generation of mice required placing sweaty underwear and husks of wheat in an open-mouthed jar. Then, waiting for about 21 days, during which time it was said that the sweat from the underwear would penetrate the husks of wheat, changing them into mice. Although that idea may seem ridiculous today, that and other ideas like it were believed and accepted during that time, which was not too long ago.
The first serious attack on the idea of spontaneous generation was made in 1668 by Francesco Redi, an Italian physician and poet. At that time, it was thought that maggots arose spontaneously in rotting meat. Redi believed that maggots developed from eggs laid by flies after observing that they had different developmental stages.. To test his hypothesis, he set out meat in a variety of flasks, some open to the air, some sealed completely, and others covered with gauze. As he had expected, maggots appeared only in the open flasks in which the flies could reach the meat and lay their eggs.
This was one of the first examples of an experiment in which controls are used. In spite of his well-executed experiment, the belief in spontaneous generation remained strong, and even Redi continued to believe it occurred under some circumstances. The invention of the microscope encouraged this silly belief. Microscopes revealed a whole new world of organisms that appeared to arise spontaneously. It was quickly learned that to create "animalcules," as the organisms were called, you needed only to place hay in water and wait a few days before examining your new creations under the microscope.
The debate over spontaneous generation continued for centuries. In 1745, John Needham, an English clergyman, proposed what he considered the definitive experiment. Everyone knew that boiling killed microorganisms, so he proposed to test whether or not microorganisms appeared spontaneously after boiling. He boiled chicken broth, put it into a flask, sealed it, and waited - sure enough, microorganisms grew. Needham claimed victory for spontaneous generation.
An Italian priest, Lazzaro Spallanzani, was not convinced, and he suggested that perhaps the microorganisms had entered the broth from the air after the broth was boiled, but before it was sealed.
Another man that made discoveries that reinforced those of Pasteur was Robert Koch. Robert Koch isolated the germ that causes tuberculosis, identified the germ responsible for Asiatic cholera, and developed sanitary measures to prevent disease. (1) In the late 1880s, genes, white blood cells, and aspirin were discovered. An Augustinian monk from Austria, Johann Gregor Mendel, experimented in the crossplanting of pea plants.
The Articles of Confederation was the United States first attempt at creating a democratic government. Instead of giving power to the central government they divided it up among the states (Kelly). This fact left the Articles with many weaknesses that ultimately led it to fail. The lack of a strong central government led to economic disorganization, no central leadership and an ineffective legislative, all which led to its downfall (Brackemyre). Leaving power to the states left the nation in a state of economic disorganization. Without the national government having the power to levy taxes, it was left with the states (Murphy). The legislature only had the right to request taxes, and it was left up to the states how they wanted to raise them, but they oftentimes weren't (Brackemyre). There was also no uniform system of currency which made trade between states difficult. The fact that states instead of Congress regulated trade led to a lack...
The Articles of Confederation were incapable of providing the United States with an effective form of government. The Articles of Confederation presided weakly over the government as it allowed little or no power to tax, control trade, and branches of government were missing. In addition to this, the thirteen states acted as separate nations and the national government had little control over them.

It contain terms agreed upon by all thirteen states and created a centralize form of government. The Articles were ratified and placed into operation on March 1, 1781. The Articles of Confederation remained in effect and was the basis of the governing body of the United States during the American Revolution. There were many defects and weaknesses that made revision of the Articles of Confederation necessary. The National Government could not form a strong Congress, because it lacked strong leadership. It did not have the power to tax states for privately own land and could not force states to obey established laws or taxation notices. Other problems the National Government faced were no military or national court system. Additionally, each state issued its own currency, and they had no money to protect it borders from Spain and Great Britain. In order for Congress to make any changes to the Articles all of the states had to be in totally agreement. The founding fathers soon discovered, conflicting views of the common good was held by reasonable

The Articles of Confederation was approved on the 15th of November in 1777 by the Second Continental Congress. The Founding Fathers had decided that because the United States had just gained their independence from a strong central government (England), they did not want to create another government like that. The Articles of Confederation gave a lot of the power to each individual state. There was not a strong central government. Under the Articles of Confederation, the National Government did not have the power to tax citizens for military reasons, draft citizens for the military, or create a common monetary system. These were just few of many things that gave fault to the Articles of Confederation. For the time being, this did not seem like a big deal for the citizens of the new country.
Government". This statement is invalid on the premise that "an unregulated global economy dominated by corporations that recognize money as their only value is inherently unstable, egregiously unequal, destructive of markets, democracy, and life, and is impoverishing humanity in real terms even as it enriches a few in financial terms." 1 John Dickenson’s original drafted model of the Articles of Confederation for the young United States as a nation was modified by Congress to protect individual powers of the states. It is important to note that the question specifies from the time of the articles ratification to the point where the first session of Congress took place under the Constitution. The Articles made a central government consisting of a unicameral legislature where each state was given a vote, with nine votes out of thirteen necessary to pass laws that were considered important; whereas a Committee of States, with one representative from each state could make minor decisions when the full Congress was not in session. An amendment of the articles required a unanimous vote. The most important powers of the government under the articles included the power to wage war, make treaties, send diplomatic representatives, and borrow money. The government lacked the power to regulate commerce, or to collect taxes, and this forced the congress to rely on the taxes which were voted by each state. The congress also did not have the power to enforce its laws. The lack of these fundamental powers rendered the government ineffective. The people involved in the crafting of the Articles as weak did so. The government put forth,...
The Articles of Confederation was the first attempt “for a new continental union of the states” (pg 38). Many states had their own written laws in place and were not anxious enough to ratify the AOC. They had concerns “over the amount of power given to the confederation government” which resulted in a delay of ratification. The Articles of Confederation consisted of a unicameral legislative body with no separation of a executive or judiciary branch or clear executive authority. In reality the states wanted to keep their own constitutions that did pay some respect to a separation of powers. “The Articles of Confederation reflected American distrust of central authority” (39) which ended up consisting up of a confederation of separate states and lack of authority. With no power to enforce regulation upon the states, a reform of the AOC needed to

Confederation, Articles of, in U.S. history, ratified in 1781 and superseded by the Constitution of the United States in 1789. The imperative need for unity among the new states created by the American Revolution and the necessity of defining the relative powers of the Continental Congress and the individual states led Congress to entrust the drafting of a federal constitution to a committee headed by John Dickinson. In the Articles of Confederation submitted by the committee to the Second Continental Congress on July 12, 1776, three points provoked much argumentthe apportionment of taxes according to population, the granting of one vote to each state, and the right of the federal government to dispose of public lands in the West. After several revisions were made, however, this constitution, comprising a preamble and 13 articles, was adopted by Congress on Nov. 15, 1777. In their final form, the Articles retained the vote by states, but based the apportionment of taxes on the value of buildings and land, and specified that no state should be deprived of territory for the benefit of the United States.
The Articles of Confederation set up a unicameral Congress in which each state had one vote. The executive authority would be in a commit...
Now during his time of teaching and being a part of administration at these different schools, he was also researching and performing studies in his labs. These breakthroughs are what Pasteur tends to be remembered for. One of his most well-known works is his work on the Germ Theory of Fermentation. Around this time many people believed in spontaneous generation. Spontaneous generation states that living organisms would develop from nonliving matter. Pasteur disproved this using boiled broths. He placed them in tubes with longs necks that did not allow particles to get in. No bacteria formed when the tube had the long filter on it. When he used regular tubes, the bacteria would form, thus proving that the origins of bacteria were caused by spores or dust particles and not by the broth itself. This began the theory of biogenesis which then caused spontaneous generations to be forgotten and disregarded. From here, Pasteur 's research showed that beers, milks, and other beverages would be spoiled due to the growth of these micro-organisms. He then invented a process of heating up the liquids in order to kill them and disinfect the liquids. This process is known as Pasteurization. He also hypothesized that micro-organisms caused human and animal diseases and could be prevented by not letting them into the body. Because of this, Joseph Lister inventing antiseptics to use in surgery, which helped to prevent diseases
The impact these men had on religious thought was tremendous. Some of them are the starting points for many of the controversies existing today. Of all the scientists, historians, and philosophers in the nineteenth century, the most influential and controversial was Charles Darwin. Born in 1809, Charles Darwin always had an interest in the nature, so he chose to study botany in college. His strengths in botany led him to become the naturalist on the H.M.S. Beagle. On a trip to South America, he and the rest of the crew visited the near by Galapagos Islands in the Pacific Ocean. It was there he noticed many different variations of the same general plants and birdshe saw previously in South America. He also observed ancient fossils of extinct organisms that closely resembled modern organisms. By 1859, all of these observations inspired him to write down his theories. He wanted to explain how evolution had occurred through a process called natural selection. In his published work, On the Origin of the Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life, or On the Origin of Species for short, Darwin stated that, "new species have come on the stage slowly and at successive intervals."(1) He also said, "old forms are supplanted by new and improved forms," and all organisms play a part in the "struggle for life.
Federalism is the system of government that divides power between a central government and the regional government. The idea of federalism came about after the American Revolution when the drafters of the Constitution were debating over the roles of the national and state governments. The Federalists carefully planned out their idea of federalism and ensured that their view would best handle their concerns and issues. In Madison’s Federalist 51, he explains many key concepts that he believed were important to the foundation of a new government. Since Madison’s Federalist 51, there have been many changes made to the federalist system, which now allows the central government to act with the original powers of the states. Although federalism has changed, it is still a very effective system of government implemented in the United States and that could be implemented anywhere.
