The Black Civil Rights Movement - 1120 Words

The history of United States is drenched in the fight for equality in the society. From women to gay rights but it is undeniable that the black civil rights was the bloodiest and most violent among them. Two methods were used to bring message to the people: the violent or the non-violent way. Most activists and civil rights group like Martin Luther King Jr., NAACP (National Association for the Advancement of Colored People) and CORE (Congress of Racial Equality) at that time chose for the latter but one did not follow that lead: the infamous Black Panthers Party. Each method had its effect on the history for the equality of African Americans. The majority of participants in the civil rights movement chose the non-violent way. Within this path, individuals and groups took different approaches to the method. There were individual protests here and there. The prominent of the black civil rights movement began after the Brown vs. Board of Education decision where the Court declared stat e laws establishing separate public schools for black and white students to be constitutional. The court case brought notice to the world about the state of African Americans. Organized Civil Rights Movements went on the rise after that. People began to apply civil disobedience to achieve their goals. Rosa Parks, a prominent figure in the Movement, was famous for her action on one of her bus rides.

Critical Disscussion Of Scient Essay Example For Students

Critical Disscussion Of Scient Essay Critically Discuss the Use of the Scientific Method in Psychology This essay examines the advantages and disadvantages of using a method primarily for gathering research on human subjects that can be examined for later use. It will give a basic outline of the methods of investigation, their uses and their suitability. I will also look at the scientific method as a whole and examine the criticisms of this method using the writings of Hume and Popper. The first method I will look at is the rt method which is built upon collected data from surveys etc. Its main plus points being that it uses a much larger sample than the other methods because it takes less time to collate the results. It is also useful because it allows for further research to be added it can be updated. There are a number of problems with this. The subjects may not feel comfortable and could answer just to please the experimenter. A big problem with the method is that it does not give enough range for the subject. The y are restricted within the boundaries of the tick boxes. The researcher can only learn so much. The laboratory experiment gives the experimenter a greater chance to control the conditions and enables you to measure behaviour with greater precision. This method also allows for quantative research and also enables greater control of variables. Although it gives the experimenter greater control, this can also seem daunting to the subject who may feel more uncomfortable and is less likely to give an natural reaction or answer. This type of research also relies on strict controlled conditions so that the experimenter can in no way affect the test or experiment. The field experiment is similar to the laboratory experiment in the way that an independent variable is manipulated but the methods differ because the field experiment tries to simulate the real life scenario more effectively. It is seen as a more valid real-life situation. The participant is unaware of the experiment and so the results are unaffected by bias. This method does not give the experimenter enough control over the independent variable being tested so examination and comparison of the results is difficult. There are ethical issues to be looked at as well because of the participants ignorance of what is taking place. For these reasons the experiment will also be difficult to replicate. The natural experiment is seen by some as a non-experiment. It does not test an independent variable but rather analyses the variables on offer. This has the highest level of ecological validity because there are no test conditions as such. Though there are many good and bad aspects of the scientific method, there is an underlying fault with all of them. The scientific method in psychology relies on empiricism. Empiricism is a view that all knowledge is derived from experience. The scientific method can ultimately be split into two attitudes. The first is the dogmatic attitude. Dogmatism is the wish to impose regularities on the basis that repetition of regularly occurring events mean that a belief in the truth of something proves that is correct. It relies on the view that you can confirm a belief by testing it. It is the product of an inductive method. It assumes that conclusions can be justified because you can repeatedly produce the same results. The critical attitude is that you can add to your belief and make it stronger through testing. Humes theory states the strength of a belief should be a product of repetition The critical attitude a method is a way of trying to establish a belief rather than trying to prove its genuineness. Popper believed then that the critical attitude is identified with the scientific attitude and that the dogmatic attitude is associated with the pseudo-scientific. Yet Popper goes further to criticise both the methods of deduction and induction. He points out The demand for rational proofs in science indicates a failure to keep distinct the broad realm of rationality and the narrow realm of certainty: it is untenable, an unreasonable demand. In fact nothing can be proved or disproved (outside of maths and logic). This is then the most important fault in the scientific method. For the scientific method to be used, then it must rely on assuming a number of things are true which are not testable within the system. They are only true to the extent that, for example, we think we have included al l the relevant variables when conducting a psychological experiment. However, this is an assumption because we have no way of knowing whether all the relevant variables have in fact been taken into consideration.

Mars Rover free essay sample

Thus the force of gravity on Mars is about one-third of that on Earth. Mars is probably the planet we know the most about since it is so close to Earth, though what we know now is not even close to everything about the planet. Over the past several decades, humans have been interested about life on mars. In 1877, Giovanni Schiaparelli, an Italian astronomer, was the first person to draw a map of Mars. His map showed a system of streaks or channels, which he called canali. In 1910, the U. S. astronomer Percival Lowell made observations of Mars and wrote a book. In his book, Lowell described Mars as a dying planet where the civilizations built an extensive network of canals to distribute water from the polar regions to the center of the planet. Mars was discovered by scientists in the 1600’s. Researchers descried a pale pink object that was only visible in the early morning just before dawn. We will write a custom essay sample on Mars Rover or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The object moved closer to the stars, got brighter over the next year and rose earlier and earlier. Then it reversed direction. Mars was the third most brightest object in the night sky, it had an intense red color and could see all night long. After moving the opposite direction for about 70 days, it reversed direction again, and gradually got dimmer. It was only visible in the evening sky and set earlier and earlier. After another year it again was a pale pink object, this time only visible just after sunset. Shortly after that, it could not be visible at all. It remained unseen for about one hundred days when the cycle began again. Each cycle took a little over two years. Scientists believed that water may have existed on the planet Mars. The total journey time from Earth to Mars takes between 150-300 days epending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target. We would need food, waste disposal, oxygen, and the matter of getting back to earth. Another reason we wouldnt send humans to mars dont know how our body would react to mars atmosphere. Mars doesnt have a magnetic field, such as earth, our planet blocks it out. If a human went to mars for a period of time there is a 40% chance they would come back with cancer. So at this time rovers are our best option. The first rover ever sent mars was in 1962 called Mariner 3. The rover never landed on mars it was a flyby which means it only took pictures of the planet while in obit. In 1965 Mariner 4 took more pictures. In 1969, flybys ended and NASA came up with spacecrafts. Mariner 9 was the first rover to take pictures of the entire surface of Mars when it landed in 1972. In the mid 70’s, they launched Viking 1 and 2, they were the first to discover ultraviolet radiation with dry soil and oxidizing nature preventing organisms from forming. The cost, to build a rover is about 2. 7 billion dollars, for us to send over humans the cost is twice as much. Sojourner, which launched in 1996 and landed in 1997, was part of the Mars Pathfinder Mission. The itty-bitty rover weighed in at 23 pounds. It was 26 inches long, 19 inches wide, and 12 inches tall. In 83 Martian days of operation, Sojourner never ventured more than 40 feet away from its lander, and its odometer for the whole trip read onl y about 330 feet. The rover snapped 550 photographs and performed tests on a rock named Yogi. In 2001 NASA discovered ice when the spacecraft Odyssey orbited Mars and took pictures. What Spirit and Opportunity found was a credit to the technology that allowed them to explore Mars. Within a couple months of landing, the Opportunity uncovered evidence of saltwater, which leaves open the possibility that life (and fossil indications) might at one time have existed on the planet. Spirit stumbled across rocks that pointed to an earlier, unrulier Mars that was marked by impacts, explosive volcanism and subsurface water [source: NASA Mars]. Water is key because almost everywhere we find water on Earth we find life, NASAs Web site. However, we are still unsure life existed on Mars. The rover Curiosity, finally landed on mars August 6, 2012, it was launched November 26, 2011. Before NASA could be launched Curiosity, the rover it had to go through series of test, drop tests, pull test, drive test, load test, stress tests, and shorting tests. So scientists had to realize that Earth and Mars revolve around the sun at different rates meaning it takes Mars 686 earths days and the Earth 365 days. They did to figure out when Mars was closest to Earth. Curiosity was launched from Cape Canaveral. Stage one, it reaches space and the tip of the cone opens and fall off. During the second stage, a centuar engine starts placing the vehicle into obit. When everything is alined the second engine starts to bring it to mars. Once Curiosity is on Mars it will do tasks such as collecting rock, soil sampling and placing them on instruments in order to be analyzed. What goes into the rover (Siceloff, Steven. Mars Rover Well-Equipped for Studies. NASAs John F. Kennedy Space Center. Nov. 22, 2011. (Dec. 9, 2011) http://www. nasa. gov/mission_pages/msl/launch/mslprelaunchfeature. html): A miniaturized gas chromatograph and mass spectrometer will separate and analyze chemical compounds in samples. A tunable laser spectrometer will look for organic (carbon-containing) compounds and determine the ratio of key isotopes both vital to unlocking Marss atmospheric and aquatic past. CheMin, an X-ray diffraction and fluorescence instrument, will measure the bulk composition of samples and detect their constituent minerals. Located on the rover arm, the Mars Hand Lens Imager will photograph rocks, soil and, if present, ice in extreme close-up. This uber-camera can spot details thinner than a human hair or focus on objects more than an arms length away. The Alpha Particle X-ray Spectrometer for Mars Science Laboratory, also located on the arm, will figure out the relative amounts of various elements present in Martian rocks and soils. Curiositys neck, or mast, is also decked out in instrumentation: The Mars Science Laboratory Mast Camera (MSLMC), attached at human-eye height, will help the rover navigate and record its surroundings in high-resolution stereo and color stills or high-definition video. The MSLMC can view materials collected or treated by the arm. Stereo hazard-avoidance cameras located further down the mast will aid the rovers navigation. Another mast-mounted instrument, ChemCam, will vaporize thin layers of material up to 30 feet (9 meters) away using laser pulses, then analyze them with its spectrometer. Its telescope can capture images of the beams target area. The Radiation Assessment Detector will monitor surface radiation levels. The Rover Environmental Monitoring Station will take readings of atmospheric pressure, temperature, humidity and wind, as well as levels of ultraviolet radiation. The Dynamic Albedo of Neutrons instrument can detect hydrogen a potential indicator of ice or water trapped in minerals up to 3 feet (1 meter) beneath the surface. Earthlings have long been fascinated by the planet Mars. Well before modern science fiction speculated about advanced civilizations upon Mars, the red planet was regarded as a malevolent agent of war, pestilence, and apocalyptic disaster inhabited with little green men. For untold millennia prior to scientific astronomy and well before there were any records which could properly be called historical, human beings recounted myths surrounding their favorite heroes and gods about Mars. It wasn’t until the 17th century when Mars was first discovered by scientists that we began to understand the red planet. The first rover sent to Mars was in 1962. The first successful mission was the 1964 trip by the Mariner 4, a United States craft that returned 21 images of the planet. In 1969 the flybys ended and In 1972 pictures were taken of the planets surface by the rover Mariner 9. Viking 1 and 2, which launched in the mid-70s, both had landers that descended to the surface of Mars. In 2003, the Mars Exploration Rover mission team launched Spirit and Opportunity, one of which was still traversing the planet as 2011 ended. Which leads us to Curiosity and 2012. Curiosity, previously known as the Mars Science Laboratory weighs 2000 pounds and has a planned mission duration of 23 Earth months, which it could exceed by quite some time, based on NASAs experience with the Spirit and Opportunity rovers. True to its old name (Mars Science Laboratory), Curiosity is packed with instruments as mentioned above. Who knows what our curiosity will lead to. Hopefully, life.

How to Increase Concentration (Studying Hack)

How to Increase Concentration (Studying Hack) The life of a student is great. You have the freedom to learn, to grow, to find yourself, hang out with your friends. Now if only you could skip over the actual studying part you might be on to something! School work is real work, and sooner or later you are going to have to buckle down and get your grey matter in gear and do some serious studying. When you need to buckle down, the ability to concentrate is an important one. If you are used to the noise of the Internet and gadgets, where you get things popping up at you right away with little to no waiting, having to sit down and focus on studying can seem like a real chore. Not to worry, help is at hand. Since you know you have to study or run the risk of flunking out of school, here are some suggestions to help you buckle down and improve your ability to concentrate when it matters: Start by getting organized Make sure that you have all the materials you need in one location. If you have to get up to go look for books or papers, concentration-killer. It will also mean that you will be spending a lot more time studying or working on your assignment than if you got organized right away. Make sure your environment is comfortable If the room is too hot or too cold, you wont be able to work effectively. Are you hungry or thirsty? Make necessary adjustments to your environment and look after these basics before you get started. You wont do your best work if you are listening to your stomach rumble. Its a good idea to have a bottle of water with you so that you can stay well hydrated while you are working. Remove distractions from your desk Take everything off your desk except for the coursework or study materials you are dealing with right now. Place other books or papers on the floor or in another location for the time being. You need to give this subject your full attention. Use your course outline as a guide If you arent sure where to start tackling the material you should be studying, pull out your course outline. Use it to give you some structure around where to start in your studying. It will list the main units that the course covers. Once you have the main units listed, you can start making a list of each chapter or section your instructor has covered. Then start filling in smaller pieces until it starts to make more sense. You should be able to see a pattern emerge as you go through this process. Try to find something interesting about the course material You may not find a course particularly interesting, but if you do some digging you should be able to find some nugget of information that is interesting about the topic. You have to do the work of studying anyway and for some courses this is going to be a stretch, but try to put the best face on the experience that you can. Dont worry about your school performance If you are worried about not doing well in your studies, you will find it very difficult to stay focused on anything you are trying to read or write. The harder you try, the more you will feel bogged down in the exercise. Try taking a few deep breaths to clear your mind and help you feel ready to settle down to work. A good technique to try is inhaling for three seconds, holding your breath for three seconds, and exhaling for three seconds. This will give you time to slow down any racing thoughts and a too-rapid heartbeat. Once you feel more centered, it will be easier for you to take in the ideas you are trying to learn. Take a break when you feel you need one If your mind starts wandering and you cant stay on topic, look at your watch. If you have been working diligently for a couple of hours without a break, get up and stretch. Have something to drink. Eat a snack or a meal if you are hungry. Give yourself a limited time to recharge and then sit back down to work so that you can concentrate anew.

Heinkel He 280 Fighter in World War II

Heinkel He 280 Fighter in World War II The Heinkel He 280 was the worlds first true jet fighter. Developed by Ernst Heinkel, the aircraft built upon his earlier successes with the civilian He 178. First flying in 1941, the He 280 proved superior to the piston-engine fighters then in use by the Luftwaffe. Despite this success, Heinkel had difficulty gaining official support for the aircraft until late 1942. Plagued by engine issues, the He 280s development was eventually halted in favor of the Messerschmitt Me 262. The He 280 represents a missed opportunity for the Luftwaffe as it could have been operational a year earlier than the more famous Messerschmitt and aided Germany in maintaining air superiority over Europe. Design In 1939, Ernst Heinkel began the jet age with the first successful flight of the He 178. Flown by Erich Warsitz, the He 178 was powered by a turbojet engine designed by Hans von Ohain. Long interested in high-speed flight, Heinkel presented the He 178 to the Reichsluftfahrtministerium (Reich Air Ministry, RLM) for further evaluation. Demonstrating the aircraft for RLM leaders Ernst Udet and Erhard Milch, Heinkel was disappointed when neither showed much interest. Little support could be found from RLMs superiors as Hermann Gà ¶ring preferred to endorse piston-engine fighters of proven design. Undeterred, Heinkel began moving forward with a purpose-built fighter that would incorporate the He 178s jet technology. Beginning in late 1939, the project was designated He 180. The initial result was a traditional looking aircraft with two engines mounted in nacelles under the wings. Like many Heinkel designs the He 180 featured elliptically-shaped wings and a dihedral tailplane with twin fins and rudders. Other features of the design included a tricycle landing gear configuration and the worlds first ejection seat. Designed by a team led by Robert Lusser, the He 180 prototype was complete by summer 1940. Aircraft designer Ernst Heinkel. Bundesarchiv, Bild 183-B21019 / CC-BY-SA 3.0 Development While Lussers team was making progress, engineers at Heinkel were encountering problems with the Heinkel HeS 8 engine which was intended to power the fighter. As a result, initial work with the prototype was limited to unpowered, glide tests which began on September 22, 1940. It was not until March 30, 1941, that test pilot Fritz Schfer took the aircraft up under its own power. Re-designated the He 280, the new fighter was demonstrated for Udet on April 5, but, as with the He 178, it failed to earn his active support. In another attempt to earn RLMs blessing, Heinkel organized a competition flight between the He 280 and a piston-engine Focke-Wulf Fw 190. Flying an oval course, the He 280 completed four laps before the Fw 190 had finished three. Again rebuffed, Heinkel redesigned the airframe making it smaller and lighter. This worked well with the lower thrust jet engines then available. Working with limited funding, Heinkel continued to refine and improve its engine technology. On January 13, 1942, test pilot Helmut Schenk became the first to successfully use the ejection seat when he was forced to abandon his aircraft. RLM Support As designers struggled with the HeS 8 engine, other power plants, such as the V-1s Argus As 014 pulsejet were considered for the He 280. In 1942, a third version of the HeS 8 was developed and placed in the aircraft. On December 22, another demonstration was organized for RLM which featured a mock dog fight between the He 280 and the Fw 190. During the demonstration, the He 280 defeated the Fw 190, as well as showed impressive speed and maneuverability. Finally excited about the He 280s potential, RLM ordered 20 test aircraft, with a follow-on order for 300 production aircraft. Heinkel He 280 Specifications (He 280 V3):GeneralLength: 31 ft. 1 in.Wingspan: 40 ft.Height: 10 ft.Wing Area: 233 sq. ft.Empty Weight: 7,073 lbs.Loaded Weight: 9,416 lbs.Crew: 1PerformancePower Plant: 2 Ãâ€" Heinkel HeS.8 turbojetRange: 230 milesMax Speed: 512 mphCeiling: 32,000 ft.ArmamentGuns: 3 x 20 mm MG 151/20 cannon Continuing Problems As Heinkel moved forward, problems continued to plague the HeS 8. As a result, the decision was made to abandon the engine in favor of the more advanced HeS 011. This led to delays in the He 280 program and Heinkel was forced to accept that another companies engines would need to be used. After assessing the BMW 003, the decision was made to use the Junkers Jumo 004 engine. Larger and heavier than the Heinkel engines, the Jumo drastically reduced the He 280s performance. The aircraft flew for the first time with the Jumo engines on March 16, 1943. With the reduced performance caused by the use of the Jumo engines, the He 280 was at a severe disadvantage to its primary competitor, the Messerschmitt Me 262. Several days later, on March 27, Milch ordered Heinkel to cancel the He 280 program and focus on bomber design and production. Angered by RLMs treatment of the He 280, Ernst Heinkel remained bitter about the project until his death in 1958. Only nine He 280s were ever built. A Lost Opportunity Had Udet and Milch seized upon the He 280s potential in 1941, the aircraft would have been in frontline service more than a year earlier than the Me 262. Equipped with three 30mm cannon and capable of 512 mph, the He 280 would have provided a bridge between the Fw 190 and Me 262, as well as would have permitted the Luftwaffe to maintain air superiority over Europe at a time when the Allies would have lacked a comparable aircraft. While engine issues plagued the He 280, this was a constant issue with early jet engine design in Germany. Messerschmitt Me 262. Photograph Courtesy of the US Air Force In most cases, government funding was lacking at the key early stages of development. Had Udet and Milch initially backed the aircraft, the engine problems most likely could have been rectified as part of an expanded jet engine program. Fortunately for the Allies, this was not the case and a new generation of piston-engine fighters, such as the North American P-51 Mustang and later versions of the Supermarine Spitfire, allowed them to take control of the skies from the Germans. The Luftwaffe would not field an effective jet fighter until the Me 262, which appeared in the wars final stages and was unable to significantly influence its outcome.

In the current day context, its distributors can be observed to have much in similarities, possessing minor differences in their application forms. Contextually, some of the major distributors offering Linux server and workstation facilities currently active can be identified as Red Hat, Debain, SUSE, Ubuntu, Slackware and Mandriva. Irrespective of their high degree of similarities, each distributor has been examined to comprise their unique strengths and weaknesses when compared with other players or their rivals. Thesis Statement The paper intends to compare and contrast Linux workstation and Linux server emphasizing on the operations performed by three different vendors namely Red Hat, SUSE, and Debain. The factors to be considered when evaluating the similarities and differences based on this context can be accounted as the total cost of ownership, training, support, performance, reliability and application availability. Linux Server and Linux Workstation and the Three Vendors A Linux server can be termed as a ‘high-power variant’ of the Linux open source operating system. The Linux server has been designed with a fundamental intention to deal with the needs of modern day business applications which is becoming majorly depended on networking and systems administration, virtual database management and web services. Linux servers are often selected over available other server operating systems due to its benefits in relation to stability, flexibility and security aspects. Similar ly, workstation is commonly regarded as a high performance desktop computer used for various purposes such as for business and trade as well as for personal and educational uses. To be specific, the Linux workstation can be noted as a computer system installed with Linux server and other Linux Operating System (OS) packages (Negus, â€Å"Linux Bible 2010 Edition: Boot Up to Ubuntu, Fedora, KNOPPIX, Debian, openSUSE, and 13 Other Distributions†). Red Hat Red Hat was established in the year 1993 which has headquartered at Raleigh, NC. Currently, Red Hay has more than 60 offices located in different parts of the world. Essentially Red Hat is considered to be the largest publicly traded technology company that is fully committed to open source. Red Hat Enterprise Linux server can be identified as a high scalable system which can effectively manage the underlying systems complexities. One of the competitive features possessed by Red Hat Enterprise Linux server products over its su bstitutes can be identified as its tendency to reduce data bottlenecks. Its mechanism which allows lower power consumption can also be considered as another competitive feature. This particular Linux server system tends to improve application performance and further ensure end to end data integrity. The Red Hat Enterprise Linux server products also provide a complete portfolio of security technologies with solution to various security challenges. Red Hat
