manic depression Essay -- essays research papers

MANIC DEPRESSION Estimates say that about 2 and a half million Americans suffer from manic depressive illness. Also called bipolar disorder, this mental illness involves episodes in which a persons mood alternates between extreme mania and depression. A person may experience pressure and racing thoughts and speech, and often uncontrolled reckless behavior. Two thirds of those who suffer from bipolar illness have numerous episodes of recurrences of alternating phases. Most people suffering from manic depressive illness experience extreme cases of up and Dow emotion. Studies say manic depression is one of the most understudied psychiatric illnesses. Bipolar disorder is much less common than depression. atleast 8 percent of people experience depression within their lives. bipolar disorder affects men and women almost equally, and is most common amongst upper economic classes. 15 percent of people with bipolar disorder commit suicide. research shows that highly creative people such as artists, composers , writers, and poets, show usually high rates of bipolar disorder. Their periods of mania is said to fuel their creativity. Bipolar disorder usually begins in a persons late teens early twenties. Men usually experience mania as the first mood episode, where as women usually experience depression first. episodes of mania and depression usually last from several weeks to several months. In most cases swings between mania and depression occur within days. In other cases a person may experience major depression and minor mania. Mania and depression may also follow patterns of seasons. Mania in the winter and fall and depression in summer and spring. People suffering from bipolar disorder feel indifferent to work and have no desire to do anything constructive. They think slow, concentrate poorly, feel tired, and experience changes, usually an increase in appetite and sleep. They often feel a sense of worthlessness and helplessness. In some cases a person may feel pessimistic about the future and may attempt suicide. a patient may all experience delusions and hallucinations. In the manic phase people feel intensely and inappropriately happy, self important and irritable. During this state a person becomes highly energized and sleeps less, talking in rapid fire speech often going off in all directions. They have inflated confidence and unfounded self esteem. Man... ... symptoms become extreme or dangerous. experts say causes can be fights between spouses or loss of sleep. A patient most likely will still suffer from some symptoms even if they follow the exact order of medicine. This illness has no cure. Doctors also have not figured out what causes bipolar disorder. Allot of patients find comfort in talking to other patients about their illness. This allows the patients to find a common bond with another person. Giving the patient the comfort of knowing someone else is going through the same thing if not worse. hospitals offer many support groups for manic depressive people. Stress is said to be the biggest cause of mania and depression occurances. Therapy is supposed to reduce a persons feeling of stress. Manic depression research as come a long way since it was first discovered. It still remains though one of the most understudied psychiatric disorders. Millions of people a year suffer from this diease. It can result in suicide, drug abuse, and unprotected sex. This illness deserves more attention then it is receiving. I feel we as a nation should address the on going rise of suicides as a cause of one form or another of manic depression.

Children and Screen Time Essay

Every parent wants nothing more then their child to succeed. They want their child to develop and learn with out struggle. In this day in age we have access to so many devices that can help contribute to a child’s success. Many will argue that a device such as a I-pad or mobile device will hinder ones learning. I feel the exact opposite will occur, and the child will gain knowledge. Children develop and learn so much at a very young age. They absorb everything they see and hear. They best learn through touch, sight, and sound. Using a device such as a touch I-pad, or I-phone a child can interact on their level. There are so many Apps available for children of all ages. They will help a child develop at their capability and speed, while learning. I feel they will absorb more knowledge with a educational hands on device rather then TV. Children have to interact and use their brains in order for the App to work. Placing a child in front of a TV to just sit and learn, they do not get the same hands on experience. There will be those arguing that placing a phone or tablet in a child’s arms will cause harm. I do not see that being true, in this day in age we use App’s for everything. Rather at the grocery store, banking, or even schools, most teach with touch devices. I feel that helping your child learn with a hands free device, will only help them in the future.

Understanding Quantum Optics

Quantum optics is a field of quantum physics that deals specifically with the interaction of photons with matter. The study of individual photons is crucial to understanding the behavior of electromagnetic waves as a whole. To clarify exactly what this means, the word quantum refers to the smallest amount of any physical entity that can interact with another entity. Quantum physics, therefore, deals with the smallest particles; these are incredibly tiny sub-atomic particles which behave in unique ways. The word optics, in physics, refers to the study of light. Photons are the smallest particles of light (though it is important to know that photons can behave as both particles and waves). Development of Quantum Optics and the Photon Theory of Light The theory that light moved in discrete bundles (i.e. photons) was presented in Max Plancks 1900 paper on the ultraviolet catastrophe in black body radiation. In 1905, Einstein expanded on these principles in his explanation of the photoelectric effect to define the photon theory of light. Quantum physics developed through the first half of the twentieth century largely through work on our understanding of how photons and matter interact and inter-relate. This was viewed, however, as a study of the matter involved more than the light involved. In 1953, the maser was developed (which emitted coherent microwaves) and in 1960 the laser (which emitted coherent light). As the property of the light involved in these devices became more important, quantum optics began being used as the term for this specialized field of study. Findings Quantum optics (and quantum physics as a whole) views electromagnetic radiation as traveling in the form of both a wave and a particle at the same time. This phenomenon is called wave-particle duality. The most common explanation of how this works is that the photons move in a stream of particles, but the overall behavior of those particles is determined by a quantum wave function that determines the probability of the particles being in a given location at a given time. Taking findings from quantum electrodynamics (QED), it is also possible to interpret quantum optics in the form of the creation and annihilation of photons, described by field operators. This approach allows the use of certain statistical approaches that are useful in analyzing the behavior of light, although whether it represents what is physically taking place is a matter of some debate (although most people view it as just a useful mathematical model). Applications Lasers (and masers) are the most obvious application of quantum optics. Light emitted from these devices is in a coherent state, which means the light closely resembles a classical sinusoidal wave. In this coherent state, the quantum mechanical wave function (and thus the quantum mechanical uncertainty) is distributed equally. The light emitted from a laser is, therefore, highly ordered, and generally limited to essentially the same energy state (and thus the same frequency wavelength).
