The Physics of the Violin essays

The Physics of the Violin essays Musical instruments are divided into four primary families, determined by the manner of their construction and the way in which they are played. These four groups are named Stringed Instruments, Keyboard Instruments, Wind Instruments, and Instruments of Percussion. The Stringed Instruments can once again be broken down into those in which the strings are plucked, for example the harp or guitar, and those in which the strings are played with a bow, such as the cello or the violin (Abele, p.1). The violin is the most important stringed instrument as it plays a chief role in orchestras and sets the fundamental design and confers its basic principles upon the lower stringed instruments, such as the viola, cello, and double bass. It is the essential and the unique design of the wood, the bridge, and the bow that provide the listener with an exclusive and distinctive sound only a violin can produce. Violinmakers have always paid particular attention to their woods selection and the characteristics of each individual piece of wood. Makers often use different kinds of wood in the different parts of the instrument. They look at important properties such as elastic modulus, acoustic velocity, and acoustic damping (Dunlop, p.37). The elastic modulus of wood is much stronger along the grain than across it, and also depends on how moist or dry the wood is along with the species of wood (Dunlop, p.38). Acoustic velocity, or the sound speed of a medium, has been measured in a wide range for different woods. Sound traveling along the grain and across the grain have produced dissimilar values with each other and among various woods. Studies show that sound passes through the wood medium at least four times faster along the grain than across the grain (Dunlop, p.38). Acoustic damping can be described as the time required for vibrations to decay. When high frequencies are played, s mall motions of atoms will generate heat and cause damping...

9 Tips for Handling a Difficult Coworker

9 Tips for Handling a Difficult Coworker No matter where you work, there always seems to be at least one coworker who is difficult to deal with. Sometimes, that coworker even turns into a bully, and that can affect your job performance and self-esteem when all you want to do it get along and get the job done. If you let it go, you can end up losing your temper, and that could adversely affect you both personally and professionally. However, there are some ways you can get along or defuse the situation to make life easier on the job. 1. Difficult CoworkersAll work situations have difficult coworkers from health care jobs to sales jobs. It may be the office gossip, the one who never seems to be able to get the job done without help or the serial dodger, who never seems to take responsibility and blames everyone else for his or her shortcomings. Then there is the nasty coworker, who never has anything nice to say about you, no matter what. Your first step in dealing with difficult coworkers is to identify who they are to ensur e you aren’t blaming the wrong person.2. Discuss the ProblemWith a workplace bully or backstabber, it may be necessary to confront the person instead of letting the behavior continue. Having a calm discussion about the problem may have a surprising response. Some people do not realize the adverse impact their statements and actions have on others and be genuinely surprised and taken aback. Try to talk reasonably and hold your temper, but let the person know that you will take the issue to a superior if the actions continue.3. Talk to a FriendA little unbiased opinion is never harmful, so talking over your coworker situation with a friend can be a good idea. It not only lets you vent your frustrations but can give you an unbiased opinion of what may be going on and how to handle the situation.4. Use Humor to Defuse a SituationWhile this type of tactic can work for some people, not everyone is able to make a humorous comment to defuse a situation spontaneously. A light bit of h umor might be the tactic for you if you have a funny side.5. Have an Exit StrategyHaving an excuse to get away from a difficult coworker can help. Whether inventing a phone call you have to make, work you have to do right away or another excuse, spend as little time with the toxic coworker as possible. When people realize they aren’t being listened to, they give up.6. Keep Your Co-Worker Problem PrivateYou don’t want your character questioned, so maintain your cool when faced with a problem co-worker. Complaining to others in the office might get you branded as a problem yourself, so keep any complaining down to those in your family or a close friend outside the office. Going public with grievances is always a bad idea.7. Be Bigger Than Your Co-WorkerYou know the old adage, â€Å"You can attract more flies with honey than with vinegar.† This applies to coworkers too. It doesn’t mean you have to come in every day with a new joke or be the person who organi zes birthday parties. However, just being pleasant, smiling and polite can improve another person’s attitude toward you.8. A Friend Can’t Be an EnemyWhile it doesn’t work in all cases, being friendly but not overly friendly to a difficult coworker can produce positive results. If the problem is gossip, having a friendly conversation can set things straight. If, on the other hand, the coworker is trying to take credit for work you have done, you can let your boss know beforehand that you are working on a certain aspect of a project, so you will get the credit.9 Go to Your BossNo one likes to do this, but sometimes there is no other choice if your requests to your toxic coworker have fallen on deaf ears. If you do decide to take the matter up with your supervisor, make sure to go armed with the information you need to make your case. Take notes on how this person’s actions are affecting your work and productivity on projects, and write down exactly what tha t person is doing to adversely affect your work.Whether working in a health care job or another field, there are ways to deal with toxic coworkers to make your job easier.

Chemistry - Essay Example This could be manifested in a person suffering from bipolar disorder or related mental illnesses. As early as 1800, pharmacological studies came up with antipsychotic drug that will help doctors during psychiatric treatment. Research and surveys showed that by the year 2005, based on the report of Archives of General Psychiatry, approximately 5.7 million of adult Americans or 2.5 percent of its population were affected by bipolar disorder (BD). There are also cases of BD found among children (Geller B, Luby J, 1997). Bipolar disorder or manic-depression is a mental disorder characterized by signs of mania or depressions which can be observed in alternating episodes. Prominently, these episodes show shifts of mood swings, from extremely energetic moods to hopeless and depressive moods. It includes one or more incidents of manic behavior, disrupted sleep, fast speech, distractibility and increase in goal-oriented-activities. Together with these manic episodes are depressive episodes characterize with lost of interest, displeasures, feeling of emptiness and unworthiness. A bio-chemical explanation was presented by scientist and researchers to explain why people tend to suffer manic-depression. Biologically speaking human brain was composed of nerve cells, neurotransmitters and receptors sending messages from one another (Prof. Hokin, University of Winconsin).Over activity or under activity in these neurotransmitters or messengers of the brain could be the reason for such disorders. So bipolar disorder could be manifested whenever brain operations has gone wrong resulting to alternating poles of mania and depression. Anti-psychotic drugs are prescribed by psychiatrists to treat bipolar disorder. These are termed to be mood stabilizers and help the patient as it goes into psychiatric treatment. The most common yet old used anti-psychotic drug nowadays is lithium. Dr.
