A Little Bit About Einstein Essay -- essays research papers fc
Albert Einstein is known as one of the greatest scientists of all time. He has propose many great theories like the Special Theory of Relativity, the Theory of General Relativity, and E=mc2. (Einstein is famous for these theories along with his help in developing the laser.) He also influences many other scientists in the study of quantum theory and the cosmos. Know one really will ever understand what went on in this man’s mind but he was defiantly one of the greatest men of all times. The following is a description of this great scientist. Albert Einstein was born in Ulm, Germany on March 14, 1879. He was born to Herman and Pauline Einstein, middle class German Jews. Einstein was a very bright child; a magnetic compass sparked his interest in the natural world, at the young age of four. Einstein began his formal education at a school in Ulm. Contrary to what you would think Albert hated formal schooling. He often did poorly in subjects such as Geography, Language, and History, but excelled in Mathematics and Science. He generally did his real studies at home where he concentrated on physics, mathematics, and philosophy. One year one of Einstein’s teachers suggested that he leave school, so at mid-term the 15 year old boy quit school. Einstein then moved to Italy to help his father in business. In 1895, he failed the entrance exam for the Swiss Federal Institute of Technology. They suggested that he studied at a Swiss school in Aarau. There he studied theories of electromagnetism, by James Clark Maxwell. At the age of 16, he wrote an essay on why he would like to study theoretical math or physics. He stated, "All above it is my individual disposition for abstract and mathematical thought, my lack of imagination in practical talent. My inclination s have also led me to resolve that is quite natural; one always likes to do things which one has talent. And there is a certain independence in the scientific profession which greatly pleases me." He graduated from the Swiss school, in 1896 at 17 years old. Then he was then accepted to the Institute of Technology in Zurich. This is where he met his first wife, Melvia Merich; she was the only girl in his physics class. They had a daughter, Lieserl, together who was given up for adoption and never see or heard of again. Th... ...es were confiscated by the Nazi government, The Nazi’s put Einstein at the top of the list of people stripped of their German citizenship. Einstein moved to the United States to escape the Nazi Germany, and also settled in Princeton New Jersey with Elsa. After World War II began Einstein urged President Roosevelt, after a series of letters, to push the study of nuclear war power and its effects. He was informed that Nazi Germany had the intelligence to create nuclear weapons of mass destruction. Einstein then became a United States citizen, he also remained a Swiss Citizen. He remained in the United States until his death in 1955. Einstein died of heart failure on April 16th in Princeton New Jersey. Einstein the was one the greatest scientists of all time, he discovered theories no one else ever even thought of, and created a completely different way to look at the natural world.

Preparation and Reactions of Boric Acid
To prepare boric acid from sodium deteriorate (borax) To carry out tests on the prepared sample of boric acid To study the physical and chemical properties of boric acid Introduction: Boron is an element in the p-block of the periodic table. It has the electron configuration of 1s22s22p1 and is in group 3 or coup 13 (PUPAS classification). In nature, it consists of two isotopes BIB (19. 6%) and BIB (80. 4%). Boron is bonded to the oxygen in nature. The important sources of Boron are borax and kerning.Boron sides and their derivatives are technologically important and are relatively inexpensive to produce. Boron oxides is very difficult to crystallite and normally exists in a glassy state (d=l . CACM-1). Molten boron oxide has a high melting point of 450 degree Celsius that is readily dissolves metal oxides to form colored borate glasses as one of the main commercial uses of boric oxide. Particularly, borosilicate glasses find wide applications in glassblowing and the production of gl ass objects. On top of the boric acid, it is also known as hydrogen borate as a weak monobasicLewis acid. At room temperature, it exists as white powder or colorless crystals with a chemical formula of HOBBS or B(OH)3. Apparatus and materials: ;Sodium deteriorate ;Concentrated hydrochloric acid ;Concentrated sulfuric acid ;Methyl red indicator ;Imitation ;Beaker ;Methanol ;Distilled water ;Electric heater ;Test tube ;Test tube rack ;Glass rod ;Suction funnel ;Suction pump ;Filter flask ;Filter paper ;Spatula ;Watch glass ;Splint Procedures: 1 . About log of sodium deteriorate (borax) is dissolved in CACM of water in a beaker. 2.The mixture is boiled and CACM of concentrated hydrochloric is added into the solution. 3. The beaker is immersed into a container with ice and water to cool down the temperature. 4. After the solution is cooled down, the boric acid is crystallized out by using the Boucher funnel, 2 layers of filter papers, suction pump and a filtering flask. 5. The remaining crystals in the beaker and on the glass rod are washed well with ice-cold water for a few times and filtered off with the Boucher funnel. 6. The yield is left aside to be dried and the weight is measured and recorded.Test 1 1. A little boric acid is inserted into a test tube. 2. Small amount of distilled water is added to dissolve the acid in the test tube. 3. A drop of methyl red indicator is added. 4. Test tube is labeled as A. 5. Steps 1 to 3 are repeated again by replacing the acid with the imitation and the test tube is labeled as B. 6. Half of each solution in test tube A and B are mixed in a test tube labeled as C. 7. All results and observation are recorded. -rest 2 1. A small amount of boric acid crystals is inserted into a Tyrant boiling tube. 2.A little ethanol is added into the boiling tube Just to cover the acid. 3. Some concentrated sulfuric acid is then added into the tube. 4. The boiling tube is held by a test tube holder and heated on a Bunsen burner. 5. The vapor produced is ignited by using a burning wooden splinter. 6. All observations are recorded. Discussion: First and foremost, we managed to yield 4. Egg of HOBBS. According to our calculation, the theoretical mass that we are supposed to obtain is 6. Egg. This means that our percentage of yield is 74. 64%. According to Vogue's Textbook ofPractical Organic Chemistry, yields around 100% are called quantitative, whereas yields above 70% are good. This means that our team did quite a great Job. Boric acid is a Lewis acid that is able to interact with the water molecules to give out hydrogen ions and dehydrogenation ion in the solution. In test 1, the methyl red indicator is used to determine the acidity of the each solution in different test tubes. The indicator can show the pH range at around 4. 4 ââ¬â 6. 2. At pH 4. 4, the solution with the indicator will appear to be in red in color and whereas at pH 6. , it will show allow. On test tube A, solution turns from colorless to pink color . This shows that boric acid is a relatively weak acid with pH around 4-5. Next on test tube B, the methyl red indicator is added into a imitation solution. The color of the solution seemed to remain unchanged. It is colorless. In fact, the solution is supposed to change from colorless to yellow. Perhaps, we accidentally made some mistakes by adding the wrong reactant in the experiment or we were a bit of too rush deciding the color of the solution without looking at it carefully.Thirdly, when we mix both he solutions from A and B, an intense pink solution is formed. This means that a stronger acid is formed. It can be simply explained by the stronger acid complex formed in between imitation and boric acid. The pH is less than 4 for sure. According to the test 2 results, a beautiful green flame is formed when we ignite the vapor with a burning wooden splinter. By mixing the alcohol (methanol) and acid (conch HOSTS) will create ester (CHI)BIBB. An alcohol flame itself is usually, ord inarily colorless. The presence of the green in the flame is indicating the ester formed contains boron element.A strong acid like concentrated sulfuric acid is needed to propionate the HOBBS and this will create the electroplate which attacks the O atom of the methanol. Without the existence of a strong acid, an intense green flame might not be formed. This is because ester may not formed and even if it is formed, it will exist in equilibrium with the alcohol & boric acid. Thus, making the green flame not really intense. There are a few precautionary steps that should be taken during this experiment. Firstly, suction pump used in test 1 is powerful and thus, 2 layers of filter papers are seed to cover the holes of the Boucher funnel.From our experience, the suction pump will cause the filter paper to be torn if only a piece of filter paper is used. Furthermore, we shall always pour the solution slowly on the rod, so that the solution will flow slowly without causing any wastage. By using this method, we can make sure the crystals are accumulated in the middle of the filter paper and it eases our Job to take out the filter paper from the funnel. On top of the safety, all acids are corrosive. In this experiment, we use concentrated hydrochloric acid and concentrated elliptic acid.We shall wear gloves and handle them with extra care to prevent and avoid any accident to occur. In addition, a tyrant boiling tube is used instead of a test tube in test 2 (flame test). A boiling tube can withstand strong heat without breakage. Test 2 (flame test) has to be carried out in the fume hood as the vapor released from the boiling tube is toxic. Therefore, we shall remain our distance with the vapor, although the green flame is beautiful. Last but not least, we shall discard the excess boric acid into the waste bottle instead of basin as to prevent water pollution.

Effective Conflict Prevention and Management Essay
We are responsible for our actions in every situation. Choosing appropriate conflict style is the key to effective conflict prevention and management. We use our favorite conflict style in conflict situations but we can choose a different style when it is needed. I have never thought of my conflict style before. The quiz provided in this course gave me an opportunity to rediscover this aspect of myself. The style of conflict management quiz tells me that I have the ââ¬Ëorangeââ¬â¢ conflict style. It tells me that I have a collaborative style of managing conflict. Cooperative problem-solving style enables people to work together so no one loses but everyone is the winner. People who use this style try to find a solution that isâ⬠¦show more contentâ⬠¦The goals of collaborating style is to integrate solutions, learning, merging perspectives, gaining commitment, and improving relationships. It works best in handling conflicts over important issues. This mode has high asse rtiveness and high cooperation. It is a best style adopted to find a solution of a conflict that would not have been generated by a single individual. This strategy works best when both sides have trust in them and are working towards a common goal. For example, if team members are establishing initial parameters for how to work effectively together, then collaborating mode could be quite useful to complete a task. The Chinese proverb is ââ¬Å"even the teeth would sometime bite the tongueâ⬠. Even in marriage conflict does arise and call for resolution. I find that the conflict style with my husband is more often collaborating but sometimes accommodating. The conflict style with my boss is different from my default ââ¬Å"collaboratingâ⬠style. I think that this relation fits better in the ââ¬Å"accommodationâ⬠category which is quite similar to the ââ¬Å"collaborationâ⬠conflict style. My conflict style is different in working with boss because the accommodat ing style is a ââ¬Å"lose-winâ⬠situation as compared to the ââ¬Å"win-winâ⬠collaborating style. A lose-win situation is when you do things for the sake of a good relationship with your boss, you would try to focus on his views first and put yourself next, ignoring the issues thatShow MoreRelatedObesity : A Study Focused On Obesity1435 Words à |à 6 Pagesnursing roles due to its accessibility and familiarity among families.
