Archimedes
Few certain details remain about the life of antiquit^s greatest
mathematician, Archimedes. We know he was born in 287 B.C. around
Syracuse from a report about 1400 years after the fact. Archimedes
tells about his father, Pheidias, in his book The Sandreckoner.
Pheidias was an astronomer, who was famous for being the author of a
treatise on the diameters of the sun and the moon. Historians speculate
that Pheidias^ profession explains why Archimedes chose his career.
Some scholars have characterized Archimedes as an aristocrat who
actively participated in the Syracusan court and may have been related
to the ruler of Syracuse, King Hieron II. We also know Archimedes died
in 212 B.C. at the age of 75 in Syracuse. It is said that he was killed
by a Roman soldier, who was offended by Achimedes, while the Romans
seized Syracuse.
Archimedes had a wide variety of interests, which included
encompassing statics, hydrostatics, optics, astronomy,
engineering, geometry, and arithmetic. Archimedes had more stories
passed down through history about his clever inventions than his
mathematical theorems. This is believed to be so because the average
mind of that period would have no interest in the Archimedean spiral,
but would pay attention to an invention that could move the earth.
Archimedes^? most famous story is attributed to a Roman architect under
Emperor Augustus, named Vitruvius. Vitruvius asked Archimedes to devise
some way to test the weight of a gold wreath. Archimedes was
unsuccessful until one day as he entered a full bath, he noticed that
the deeper he submerged into the tub, the more water flowed out of the
tub. This made him realize that the amount of water that flowed out of
the tub was equal to the volume of the object being submerged.
Therefore by putting the wreath into the water, he could tell by the
rise in water level the volume of the wreath, despite its irregular
shape. This discovery marked the Law of Hydrostatics, which states that
a body immersed in fluid loses weight equal to the weight of the amount
of fluid it displaces.
There are three main mechanical inventions credited to
Archimedes. The first one is the Archimedean screw which supposedly could serve as a water pump. The second invention was the compound pulley. The third invention
was the way of finding the volume of something by displacement as
demonstrated in the story above. Most historians would agree that more
important than his great mechanical inventions were his mathematical
discoveries.
The mathematical works that have been presented to us by
Archimedes could be classified into three groups. The first
group consists of works that have as their major objective the proof of
The First World War was monumental in history because of all the new technology that was introduced. One particular area that developed during the Great War was the use of airplanes by the German and Allied militaries. In comparison, they both had different mentalities towards an invention that was only made successful less than a decade before the outbreak of war in 1914 by the Wright Brothers in North Carolina, United States. The German Military welcomed the idea with open arms, investing in its potential for military uses, whereas the Allies remained reserved and hesitant, claiming that aircraft could not be used for anything more offensive than reconnaissance missions. These differences in opinions later affected the development of each air force. The German military kept making consistent improvements to their equipment whereas the allied pilots were slow in their respective air force evolution. However, there was a common progression that both militaries had which was the slow phasing out of the cavalry on either side due to the effectiveness of the aircrafts reconnaissance and battle capabilities. During the World War One, the German military took advantage of the new technology available to them, which gave significant results, whereas the Allies had a more traditional mindset and followed behind at a slower pace.
Evidence: Drones have many beneficial uses, including in search-and-rescue missions, scientific research, mapping, and more. But deployed without proper regulation, drones equipped with facial recognition software, infrared technology, and speakers capable of monitoring personal conversations would cause unprecedented invasions of our privacy rights. Interconnected drones could enable mass tracking of vehicles and people in wide areas. Tiny drones could go completely unnoticed while peering into the window of a home or place of worship.
New technology is arriving every day. The greatest invention during this time was the steam engine. The creation of the steam engine was credited to James Watt. There had been other steam engines before James Watt’s, but none of them were efficient. Watt’s engine was the first efficient engine that could be used in a factory.
in the year 1182 in the town of Assisi in Italy. His father's name was
Perhaps one of the greatest accomplishments of the 3rd century was made by Eratosthenes, who calculated the circumference of the earth within 300 miles of its actual distance. Also, the Alexandrians made great leaps forward in the field of medicine. Hippocrates, who is regarded as the father of modern medicine wrote 53 books on medicine. Later, Herophilus became the first to dissect a human corpse and document in great detail the inside of a human body. Furthermore, he and almost all Egyptian, Greek, and Roman doctors put great stress on the importance of hygiene, diet, exercise and bathing, which are still some of the foundations of modern health. However, the greatest overall advancements that the Alexandrians made great were technological advancements. One man who helped move technology of the ancient world forward the most was Hero, who invented the water clock and the steam turbine. Some of the inventions created by the Alexandrians are still used today, such as levers, pulleys, pumps, screws, springs, and
It can be asserted that with current technology and supervision drones lack the stability required to be successful and safe and in actuality are counter-effective because these drones create an unsupervised means of power that could quickly spiral out of control. The drone program fails to decrease the death count of war, increase the intelligence needed to dismantle terrorist cells and be secure against hackers. As a result, drones are counterproductive, and in truth create a newfound terrorism. At the end of the day, the only means to eradicate the enemy is to make them a friend.
War can be defined as “an organized and deliberate political act by an established political authority, which must cause 1,000 or more deaths in a twelve-month period, and which requires at least two actors capable of harming each other” (253, Mingst.) This is a broad definition as war can take several different forms, categorized in various ways. Today, the United States is engaged in the War on Terror. In a post-9/11 world, terrorist attacks are even greater sources of fear to citizens, as well as massive threats to national and international security. Over the past few decades, terrorists have been successful in increasing support and achieving political aims. This poses a major security dilemma to victims, such as the United States. It is this sense of insecurity that leads to military action. Any sense of threat is likely to send a nation to arms (251-252, Mingst.) The U.S. government thus must decide as to what the best course of action would be, in protecting the nation. Over the past decade, drone use has increased exponentially for this purpose. These unmanned aerial vehicles, or drones, are often used in attempts to eliminate terrorism. While it is evident that terrorism poses massive threats to the nation, drone strikes are not conducive to a just war.
This study addresses how the Department of Homeland Security has incorporated unmanned aircraft to protect America’s borders. The Department of Homeland Security received authorization in 2003 to purchase one Predator Unmanned Aircraft System (UAS) (Barry 2013). The Predator B is stationed at Sierra Vista, Arizona and flies in support of securing the border between Mexico and the U.S... Unmanned aircraft bring a new and dynamic advantage when it comes to surveillance and incorporating cutting edge technology. During FY13, the Border Patrol seized 2,428,419 pounds of marijuana along the Southwest, border according to U.S. Department of Homeland Security (2014). Is the Department of Homeland Security employing unmanned aircraft to their full capacity to secure A...
Coming out is never easy for anyone and when paired with being married and having kids and learning how to survive according to male construct in a heterosexually dominant society, it becomes even more difficult to define one’s sexuality.
Arising issues and questions surrounding drones are brought up in hundreds of articles. Articles from The Washington Times, The New York Times, and Global Research highlight the legal aspects and issues. These articles introduce several facts and some opinions on the idea of Drones coming on American Soil.
By using drones in worldwide assaults, the US sets a dangerous example to the many other nations with similar technology. Because America sends military drones instead of actual troops into areas like Pakistan and Yemen, it runs the risk of allowing its enemy countries to conduct similar strikes against its very own home front (Benjamin). While the US, UK, and Israel are the only world powers that currently contain armed drone machines, the US’s frequent uses of these modernized arsenals will influence other nations into building their own military drones to threaten our nation’s security in the upcoming years (Mulrine). This is already seen in countries like ...
Should countries be allowed to use drones in modern countries? Since the installment of drones in warfare, the unmanned aerial combat vehicle has proven to be quite an effective tool. Nowadays, the efficiency of drones has overpowered the opposing arguments since it has more pros than cons. By defining the importance to keep military personnel safe, by providing coherent data on civilian lives, and by refuting the significance of drones to keep terrorism at bay, one will be enlightened to see that drones are the way of the future.
Euclid of Alexandria was born in about 325 BC. He is the most prominent mathematician of antiquity best known for his dissertation on mathematics. He was able to create “The Elements” which included the composition of many other famous mathematicians together. He began exploring math because he felt that he needed to compile certain things and fix certain postulates and theorems. His book included, many of Eudoxus’ theorems, he perfected many of Theaetetus's theorems also. Much of Euclid’s background is very vague and unknown. It is unreliable to say whether some things about him are true, there are two types of extra information stated that scientists do not know whether they are true or not. The first one is that given by Arabian authors who state that Euclid was the son of Naucrates and that he was born in Tyre. This is believed by historians of mathematics that this is entirely fictitious and was merely invented by the authors. The next type of information is that Euclid was born at Megara. But this is not the same Euclid that authors thought. In fact, there was a Euclid of Megara, who was a philosopher who lived approximately 100 years before Euclid of Alexandria.
The U.S Air Force trained 350-drone pilots in 2011 and only 250 bomber and fighter pilots were trained that year. There are a total of 16 drone operating and training sites across the United States with a 17th site in the works. There are also twelve U.S drone bases outside the U.S. More time and money are being spent on drones than on other capabilities, and can sometimes be useless with certain threats. Drones are very easy to shoot down, Drones must have clear airspace to operate, which would be useless against enemy’s like North Korea and Iran. Drones also require extensive maintence and have a high crash rate. Drones rely on cyber-connections to operate, which are increasingly vulnerable. Another problem with drones is that they destroy crucial evidence that could really benefit the U.S with counterterrorism. Whenever the U.S uses drones to kill suspected terrorist, they lose the chance to find out what he was planning, whether anyone else was involved or if he was even a terrorist. Drone attacks distinguish the chances of arresting and interrogating the suspected terrorist. Its important to note that drones don’t seize hard drives, organizational charts, strategize plans or secret correspondence, and the effectiveness of the drone is based on human operating. And humans are far from perfect, which just opens up a whole new door
Galileo was probably the greatest astronomer, mathematician and scientist of his time. In fact his work has been very important in many scientific advances even to this day.
