What is Love Essay - 648 Words

Love, Love, Love. We all think about it, dream about it, sing about it, and even lose sleep worrying about it, but why? Love is such a small word paired with a vital meaning. It’s universal, easy to spell, difficult to define, but impossible to live without. When we don’t have it, we search for it, when we find it, we don’t know what to do with it, when we have it, we fear losing it. Love is the constant source of happiness and sorrow. I am young and I havent a clue as to what love is, let alone what falling in love is. However, I have my ideas of what love is like. I have never witnessed the beauty of people falling in love, or the severity of those falling out of love, so what is love? Love in general could be frightening. Some†¦show more content†¦I think falling in love with someone happens when you least expect it to, when youre too busy focusing on other aspects of your life. This is where fate comes into play. That specific person was led to you for some unknown reason. Out of the blues, it’s like your knight in shining amour that you have longed to be with finally found his/her way to you. There are people in this world that think they may never fall in love again. You fall at times, but you get back up. You will love again, and you will also trust again. You have to simply let things get themselves done, thats when you know its meant to be, because destiny took its course, and while you were too busy doing something else, the love of your life came along. Love dates way back to when the world began. In reality, we really have no idea what love truly is. Raising questions like, is it even real? We watch love movies, read romance novels, but thats the sugar-coated, sweet and simple version of it. Meeting someone, fall in love, get married, have kids, spend the rest of your lives together. What about the suffering we have to endure when falling in love? Risking everything for that one person? And even when we feel weve reached the end of the road, this person has the power to leave us at any given moment. We put ourselves out there with the chance they can break us apart.

Discriminatory laws and riots due to increased tension between immigrants and white settlers. Labor unions were active in the cities. Social reform movements arose in Ohio and Illinois. In rural areas, farmers were also politically active. It was a region in which social and political campaigns took root. Social The growth of industry highlighted the gap between rich and poor. Wealthy entrepreneurs wanted to increase profits. Workers wanted better wages and working conditions. The post-Civil War South continued to have problems related to race. New laws regarding segregation made it hard for southern African Americans to enjoy the improved and rebuilt transportation. The willingness of the immigrants from China to work for lower wages and the cultural differences between them and the white settlers led to friction. Like the Northeast, the Midwest had waves of immigrants come to its cities. The gap between rich and poor was a source of friction. Economic or Type of Economy The Northeast remained the leading industrial region in the Second Industrial Revolution. New York, Massachusetts, and Pennsylvania produced more than 85 percent of all U.S. industrial products in 1890. The war ended slavery, which took away the South’s main source of labor. Although it remained mostly agricultural, the South began developing its timber industry. Coal and iron deposits in the southern Appalachian Mountains gave rise to steel  production in Birmingham, Alabama. Agriculture became more efficient in the Midwest and also encouraged settlers to obtain land in the West. However, the sparse population of the West did not support much industrial growth, and the economy continued to be based on natural resources. This region experienced economic growth in both farming and manufacturing. The upper Midwest states became centers of industry and a hub for shipping and transport. Population Change The rapid growth of a manufacturing economy created a need for workers. Cities in the Northeast became destinations for the immigrants that came to the United States. By 1870 about 15 percent of the U.S. population was foreign born. About one of every five industrial workers was an immigrant. Most of these immigrants settled in the Northeast. Many African Americans left the South to work in new factories in the North and Midwest. There they had a better chance of earning good wages and improving their economic and social standing. Immigrants from China arrived in the West looking for jobs on the expanding railroads. The thinly spread population of the West did not support much industrial growth. Cities grew rapidly, attracting large numbers of immigrants. Chicago, Illinois became one of the nation’s largest cities during this period. In 1860, the city’s population was about 110,000.

Explain how the Second Industrial Revolution affected the North, South, West, and Midwest. Which region would you have preferred to live in during this period? Why? The Second Industrial Revolution affected the North, South, West, and Midwest with changes such as population, transportation, and economy changes. The rapid growth of the manufacturing economy in each region created a need for workers attracting many immigrants. By 1870 about 15 percent of the U.S. population was foreign born and, about one of every five industrial workers was an immigrant. In addition, each region also developed and improved their transportation system, usually, by railroads. These railroads connected cities and were used to transport natural resources and goods from manufacturers to other places. Moreover, each region had their own type of economy. The northeast remained the leading industrial region and the south and west maintained a developing agricultural economy but, the west’s sparse population did not support much industrial growth. Also, the Midwest experienced economic growth in both farming and manufacturing. Furthermore, if I had to live in a certain region during the Second Industrial Revolution period I would prefer to live in the northwest region which was the leading industrial region in both the First Industrial Revolution and Second Industrial Revolution. The rapid growth of the economy begged for more workers so it would have been easy for me to find a job and provide for my family. The northeast region benefited, improved, flourished more than any other region in both Industrial Revolutions and I would have wanted to be a part of that experience.

A Man for All Seasons Story Essay Example

A Man for All Seasons Story Essay Many times in literature characters follow a common flow with society. In the story A Man For All Seasons by Robert Bolt, the Common Man is a conformist who highlights many important roles of society in England during the fifteenth century. The Common man appears throughout the play as: Sir Thomas More’s steward named Matthew, a boatman, a publican, a jailer, a jury foreman, and a headsman who decapitates Sir Thomas More. The significance of the Common Man lies in his role in representing society as an individual and as a foil to Sir Thomas More. The Common Man is first introduced in the play as Sir Thomas More’s steward, Matthew. Matthew is very effective in expressing the role of the common man because he takes part in much slander in order to benefit himself such as in Act One Matthew takes money from Chapuys and Cromwell and gives them information about Sir Thomas More in return. In the opening of the play Matthew is displeased with Sir Thomas More’s generosity when he gives the silver cup to Richard Rich. Matthew replies to this act by saying â€Å"My master Thomas More would give anything to anyone. We will write a custom essay sample on A Man for All Seasons Story specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on A Man for All Seasons Story specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on A Man for All Seasons Story specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Some say that’s good and some say that’s bad, but I say he can’t help it and that’s bad because some day someone is going to ask him for something that he wants to keep; and he will be out of practice. There must be something that he wants to keep. That’s only common sense. † This quote is very significant because it foreshadows Sir Thomas More’s death. Sir Thomas More could have prevented his death if he would have given up his sense of self and went against his conscious and beliefs. Another significant act by Matthew is in Act Two, Sir Thomas can no longer afford Matthew and so More dismisses Matthew from his home. Matthew seeks employment from Richard Rich; this shows the common man’s only concern for himself and his aloofness to any loyalty to Sir Thomas More. In Act One the Common Man takes on the role of the Boatman. The Boatman most closely represents society of our time because he complains about his low income and his aging wife. When More asks the boatman for a ride home the boatman replies â€Å"Bless you sir – that’s all right. I expect you’ll make it worth my while, sir. † This quote indicates that the boatman is looking for money, as most characters played by the Common Man behave. In Act Two the Common Man plays the role of a jailer. The Jailer also is guilty of complaining about his low wages. More continues to go against the flow of society even more as the story progresses. As king Henry said in Act One to Sir Thomas â€Å"There are those like Norfolk who follow me because I wear the crown, and there are those like Master Cromwell who follow me because they are jackals with sharp teeth and I am their lion, and there is a mass that follows anything that moves – and there is you. † This quote implies the decisive difference between Sir Thomas More and the Common Man. It establishes his role as the counter part of the Common Man which is the role of the man for all seasons. The last character played by the Common Man is the Headsman. It is ironic that the Common Man plays the role of decapitating Sir Thomas More. It is important to realize that this is not a symbol of society defeating Sir Thomas More, rather it shows that Sir Thomas More is loyal enough to his self that he was able to face death even at the hands of the Common Man. As one can see, the role of the Common Man throughout the play A Man For All Seasons by Robert Bolt emphasizes the moral of the play. The significance of Sir Thomas More would not be expressed so greatly without the roll of the Common Man.

How a Gamble Paid Off

How a Gamble Paid Off Several years ago, I spent ten days in Las Vegas on business. I allowed myself only twenty dollars to gamble with and am proud to say I broke even. After my home state approved the lottery, people lined up to buy the prized tickets. Not I. I can probably count on one hand the number of lottery tickets Ive bought. Im just not that much of a gambler. But the one time I did gamble, it paid off in a big way. A very big way. I had this completed manuscript titled Wink of an Eye gathering dust in my file drawer when I saw a notice in FundsForWriters for the St. Martins Press/Private Eye Writers of America Best 1st PI Novel competition. The manuscript met all the criteria for submission so I stuffed it in an envelope, scraped together the thirty dollar entry fee and mailed them off. To others, thirty dollars may not seem like a lot, but at that time I was unemployed and on the last weeks of collecting unemployment. It was a weeks worth of groceries. But I took a chance, crossed my fingers and said a prayer. Time went Then one day many weeks later, there in my inbox was an email from St. Martins Press. They were pleased to advise me Wink of an Eye had been chosen as a finalist for the competition. I remember being super excited that it could garner a publishing contract or some other kind of notice as a second place, third place, or honorable mention submission, because surely it wouldnt win. A week later, I received another email from St. Martins advising me my manuscript, Wink of and Eye, had won the competition. The prize was a ten thousand-dollar advance and publishing contract. Not a bad return on a thirty-dollar investment. Im still not much of a gambler, but I will take a second look at contests with big prizes now. If you consider entering your work in a contest, there are a few things to consider. First, is the entry fee fair in relation to the prizes? I saw a recent call for submissions where the entry fee was forty dollars with a hundred-dollar prize. You do the math. Secondly, winning a contest does not mean your winning entry will be published, unless the prize is publication. In that case, you still must read the contest rules and regulations, and contract if offered, thoroughly, to determine if the rights taken and means published fit your preferences. And lastly, entering your unpublished work in a contest should carry the same polish as if you were submitting to a publisher. Revise, edit, proofread. Repeat. The process should be the same whether its going to a contest, small press, or big house. Not all contests are equal, but there are some really good ones out there. And they can be an excellent way of getting your foot in the door and reaching an audience, if youre willing to take the gamble.

Radiation in Space and Astronomy - Definition

Radiation in Space and Astronomy - Definition Astronomy is the study of objects in the universe that radiate (or reflect) energy from across the electromagnetic spectrum. Astronomers study radiation from all objects in the universe. Lets take an in-depth look at the forms of radiation out there. Artwork of a planet orbiting a pulsar. Pulsars are very rapidly spinning neutron stars are the dead cores of massive stars and rotating on their axes often hundreds of times every second. They radiate radio waves and in optical light. Mark Garlick/Science Photo Library (Getty Images) Importance to Astronomy In order to completely understand the universe, scientists must look at it across the entire electromagnetic spectrum. This includes the high-energy particles such as cosmic rays. Some objects and processes are actually completely invisible in certain wavelengths (even optical), which is why astronomers look at them in many wavelengths. Something invisible at one wavelength or frequency may be very bright in another, and that tells scientists something very important about it. Types of Radiation Radiation describes elementary particles, nuclei, and electromagnetic waves as they propagate through space. Scientists typically reference radiation in two ways:  ionizing and non-ionizing. Ionizing Radiation Ionization is the process by which electrons are removed from an atom. This happens all the time in nature, and it merely requires the atom to collide with a photon or a particle with enough energy to excite the election(s). When this happens, the atom can no longer maintain its bond to the particle. Certain forms of radiation carry enough energy to ionize various atoms or molecules. They can cause significant harm to biological entities by causing cancer or other significant health problems. The extent of the radiation damage is a matter of how much radiation was absorbed by the organism. The electromagnetic spectrum show as a function of frequence/wavelength and temperature. Chandra X-Ray Observatory The minimum threshold energy needed for radiation to be considered ionizing is about 10 electron volts (10 eV). There are several forms of radiation that naturally exist above this threshold: Gamma-rays: Gamma rays (usually designated by the Greek letter ÃŽ ³) are a form of electromagnetic radiation. They represent the highest energy forms of light in the universe. Gamma rays occur from a variety of processes, ranging from activity inside nuclear reactors to stellar explosions called  supernovae and highly energetic events known as gamma-ray bursters. Since gamma rays are electromagnetic radiation, they do not readily interact with atoms unless a head-on collision occurs. In this case the gamma ray will decay into an electron-positron pair. However, should a gamma ray be absorbed by a biological entity (e.g. a person), then significant harm can be done as it takes a considerable amount of energy to stop such radiation. In this sense, gamma rays are perhaps the most dangerous form of radiation to humans. Luckily, while they can penetrate several miles into our atmosphere before they interact with an atom, our atmosphere is thick enough that most gamma rays are absorbed b efore they reach the ground. However, astronauts in space lack protection from them, and are limited to the amount of time that they can spend outside a spacecraft or space station. While very high doses of gamma radiation can be fatal, the most likely outcome to repeated exposures to above-average doses of gamma-rays (like those experienced by astronauts, for instance) is an increased risk of cancer. This is something that life sciences experts in the worlds space agencies study closely. X-rays: x-rays are, like gamma rays, a form of electromagnetic waves (light). They are usually broken up into two classes: soft x-rays (those with the longer wavelengths) and hard x-rays (those with the shorter wavelengths). The shorter the wavelength (i.e. the harder the x-ray) the more dangerous it is. This is why lower energy x-rays are used in medical imaging. The x-rays will typically ionize smaller atoms, while larger atoms can absorb the radiation as they have larger gaps in their ionization energies. This is why x-ray machines will image things like bones very well (they are composed of heavier elements) while they are poor imagers of soft tissue (lighter elements). It is estimated that x-ray machines, and other derivative devices, account for between 35-50% of the ionizing radiation experienced by people in the United States.Alpha Particles: An alpha particle (designated by the Greek letter ÃŽ ±) consists of two protons and two neutrons; exactly the same composition as a hel ium nucleus. Focusing on the alpha decay process that creates them, heres what happens: the alpha particle is ejected from the parent nucleus with very high speed (therefore high energy), usually in excess of 5% of the speed of light. Some alpha particles come to Earth in the form of cosmic rays  and  may achieve speeds in excess of 10% of the speed of light. Generally, however, alpha particles interact over very short distances, so here on Earth, alpha particle radiation is not a direct threat to life. It is simply absorbed by our outer atmosphere. However, it is a danger for astronauts.   Beta Particles: The result of beta decay, beta particles (usually described by the Greek letter Î’) are energetic electrons that escape when a neutron decays into a proton, electron, and anti-neutrino. These electrons are more energetic than alpha particles but less so than high energy gamma rays. Normally, beta particles are not of concern to human health as they are easily shielded. Artificially created beta particles (like in accelerators) can penetrate the skin more readily as they have considerably higher energy. Some places use these particle beams to treat various kinds of cancer because of their ability to target very specific regions. However, the tumor needs to be near the surface as not to damage significant amounts of interspersed tissue.Neutron Radiation: Very high-energy neutrons are created during nuclear fusion or nuclear fission processes. They can then be absorbed by an atomic nucleus, causing the atom to go into an excited state and it can emit gamma-rays. These photons will then excite the atoms around them, creating a chain-reaction, leading to the area to become radioactive. This is one of the primary ways humans are injured while working around nuclear reactors without proper protective gear. Non-ionizing Radiation While ionizing radiation (above) gets all the press about being harmful to humans, non-ionizing radiation can also have significant biological effects. For instance, non-ionizing radiation can cause things like sunburns. Yet, it is what we use to cook food in microwave ovens.  Non-ionizing radiation can also come in the form of thermal radiation, which can heat material (and hence atoms) to high enough temperatures to cause ionization. However, this process is considered different than kinetic or photon ionization processes. The Karl Jansky Very Large Array of radio telescopes is located near Socorro, New Mexico. This array focuses on radio emissions from a variety of objects and processes in the sky. NRAO/AUI Radio Waves: Radio waves are the longest wavelength form of electromagnetic radiation (light). They span 1 millimeter to 100 kilometers. This range, however, overlaps with the microwave band (see below). Radio waves are produced naturally by active galaxies (specifically from the area around their supermassive black holes), pulsars and in supernova remnants. But they are also created artificially for the purposes of radio and television transmission.Microwaves: Defined as wavelengths of light between 1 millimeter and 1 meter (1,000 millimeters), microwaves are sometimes considered to be a subset of radio waves. In fact, radio astronomy is generally the study of the microwave band, as longer wavelength radiation is very difficult to detect as it would require detectors of immense size; hence only a few peer beyond the 1-meter wavelength. While non-ionizing, microwaves can still be dangerous to humans as it can impart a large amount of thermal energy to an item due to its interactions with water and water vapor. (This is also why microwave observatories are typically placed in high, dry places on Earth, as to lessen the amount of interference that water vapor in our atmosphere can cause to the experiment. Infrared Radiation: Infrared radiation is the band of electromagnetic radiation that occupies wavelengths between 0.74 micrometers up to 300 micrometers. (There are 1 million micrometers in one meter.) Infrared radiation is very close to optical light, and therefore very similar techniques are used to study it. However, there are some difficulties to overcome; namely infrared light is produced by objects comparable to room temperature. Since electronics used to power and control infrared telescopes will run at such temperatures, the instruments themselves will give off infrared light, interfering with data acquisition. Therefore the instruments are cooled using liquid helium, so as to lessen extraneous infrared photons from entering the detector. Most of what the Sun emits that reaches Earths surface is actually infrared light, with the visible radiation not far behind (and ultraviolet a distant third). An infrared view of a cloud of gas and dust made by Spitzer Space Telescope. The Spider and Fly Nebula is a star-forming region and Spitzers infrared view shows structures in the cloud affected by a cluster of newborn stars. Spitzer Space Telescope/NASA Visible (Optical) Light: The range of wavelengths of visible light is 380 nanometers (nm) and 740 nm. This is the electromagnetic radiation that we are able to detect with our own eyes, all other forms are invisible to us without electronic aids. Visible light is actually only a very small part of the electromagnetic spectrum, which is why it is important to study all other wavelengths in astronomy as to get a complete picture of the universe and to understand the physical mechanisms that govern the heavenly bodies.Blackbody Radiation: A blackbody is an object that emits electromagnetic radiation when it is heated, the peak wavelength of light produced will be proportional to the temperature (this is known as Wiens Law). There is no such thing as a perfect blackbody, but many objects like our Sun, the Earth and the coils on your electric stove are pretty good approximations.Thermal Radiation: As particles inside of a material move due to their temperature the resulting kinetic energy can be described as the total thermal energy of the system. In the case of a blackbody object (see above) the thermal energy can be released from the system in the form of electromagnetic radiation. Radiation, as we can see, is one of the fundamental aspects of the universe. Without it, we would not have light, heat, energy, or life. Edited by Carolyn Collins Petersen.
