A New Age in Space Exploration? :: Space Exploration Essays

â€Å"A Renewed Spirit of Discovery† was the title of President Bush’s speech for his vision of new Space Exploration. Since the debate was given on January 14, 2004, it has produced viable concerns from those who support and oppose the initiative. Arguments for and against it have appeared in all types of media, and more importantly in the minds of Americans. This Literature Review will discuss many of these beliefs in order to achieve a well-rounded, objective analysis of the issue. But before any opinions are put forth, it is always important to talk about the relative facts. Why put forth a new vision? Over past 30 years, it is hard to say that we have â€Å"explored† space. It is more appropriate to say we have conquered manned flight in Earth’s lower orbit. Truly, the Apollo Missions to the moon, which ended in the mid 70’s, was also the end to Manned Space Exploration. We have continued to build satellites and space stations to orbit the earth, and robots and satellites to explore Mars and Deep Space. By proposing to put humans on the Moon and Mars, the President has not changed our manned space exploration policy; he has created one. President George W. Bush proposed a new age in Space Exploration on January 14, 2004. The Space Shuttle Columbia disaster was only part of his reasoning for announcing a new direction for NASA. A reason not as well known is the current lack of any direction for NASA. Other than sending probes and robots to Deep Space and Mars, NASA has continued to upgrade current projects like the Hubble Space Telescope. [3] Not since the design of the Space Shuttle around 1980 has a new and demanding project been given to NASA. It is essential that the brilliant minds at NASA be pushed to greatness. The President’s new plan for Moon and Mars landings will provide the direction and new energy needed for NASA [2]. NASA Director Sean O’ Keefe has fully agreed with the need to challenge NASA and push its abilities to another level. Space Exploration History Humans are constantly exploring new horizons, which in turn raise the bar for new ideas to conquer the next step in exploration. New goals force the development of new technologies, which in turn are used to design technologies that affect everyday Americans.

Computer in Life Essay

What do you think of when you hear the word ‘computer’? Do you think of technology? Or maybe one of the ways to get on Facebook which I am sure many of you are thinking right now or you might even imagine a boring office full of screens and keys with people typing frantically in front of. All of those visions are correct, but first let’s take a look at the history of several inventions that led the creation of computers which has dramatically changed the world of technology. The first machine that was invented, which worked like a computer, was a gear-powered German device dubbed the Calculating Clock created by Wilhelm Schickard in 1623. It operated by pulling or pushing rods set inside a glass case. 20 years later, in 1640s, a similar device known as a Pascaline was invented and became famous dramatically.. In 1944, the Harvard Mark-1 computer was completed. That computer was approximately similar to a modern computer, but it was a large calculator driven by a camshaft with no stored programs. This massive computer filled a large room and was a joint effort between Harvard University and IBM. Personally, I believe that one of the most important inventions in my life has always been a computer. I was raised in this technological world where computers are a necessity. Computers dramatically transform my life in terms of education. They acknowledge me with the events that happen around the world, which I think are extremely important to learn. They give me an efficient, convenient and cozy way of work and study. Computers do not just provide me with education or learning experiences, but they are also one of the means of entertainment and globalization. They provide me with leisure time watching movies online or listening to music. According to me, it is one of the most relaxing ways to release the stress from studying and working day and night. Also in terms of globalization, with the aid of computers, I can visualize and make conversations with my long distance family and friends. They assist me in keeping relations with my family and friends, even though I am extremely far from them. I, as a student, strongly believe that computers are extremely important in terms of education as I mentioned before. Before computers were invented, I (you were born after computers were invented) as well as everyone else relied on books to provide them with educational knowledge. Now that computers are available, I never search through hundreds of pages of books. I can just surf the Internet in the blink of an eye to research for learning information. If I need to type anything or write an essay, I have easy access to my Microsoft word or Notepad in which I can also save the information and open it whenever I desire to and if I make any errors typing, it provides me with the correct word or information. Isn’t that amazing? It’s like a human sitting in the back of the computer screen reading my essay and correcting it of any mistakes I may make. Furthermore, the computers also assist me when it comes to math, such as math problems like logarithms, sine, cosine, and tangent can be awfully difficult to calculate and may take students a long time to do so manually. Luckily, with the help of computers, students may turn a five-minute problem into a one-minute problem. Computers have also made a major impact in the business field. They have gained importance as they have increased the productivity and efficiency of workload. Large amounts of data in the personal lives as well as in business and industrial sectors are stored on computers. Overall, as I provided you with all the benefits of computers, according to me, computers are one of the necessities in today’s technological world. In today’s world, it is almost impossible to think that one can survive without computers. They have become a gadget of almost daily use for people of every age. With the computer industry growing rapidly, the computer technology has also brought about a revolution of laptops and palmtops replacing the desktop, which are still popular in many of the industries. With the reduction in size, it has become quite easy to carry the computers and use them to the fullest. Computers are extremely helpful in terms of education, entertainment, globalization, etc. People might think that there might be negative aspects to the inventions of computers, but as far as I am concerned, I do not believe that the statement is true. The computers have had numerous positive effects and they will continue to do so in the future as well.

This is a horrible disease that is attacking many women as well as men each day. Although it is known for men to develop the disease, it is mainly common among women. I have several friends and one real close friend that has battled with breast cancer. Don’t waste time! Our writers will create an original "Breast Cancer Problem" essay for you Create order Between the treatment, surgery and the pain one goes through, it is awful. Personally, my oldest daughter and myself have dealt with what is known as borderline cells and had to surgically have them removed. It was a very scary time for both of us. Breast cancer is one of the top ten most common cancers among women in the United States and it is one of the increasing public health problems that we have today (Starr, Biology Life Science, 11th edition). Description Breast cancer develops in breast tissue, usually in milk ducts or glands. At the beginning, breast cancer starts as a malignant tumor, a cluster of abnormal cells, which grow and invade surrounding healthy tissue (UAB Medicine 2018). Depending on the type of breast cancer and when it hits the blood system, the breast cancer can travel rapidly. Lumps that can be found in the breast are called signs of early detection. It is important for a woman to be familiar with her on breast so she might detect any changes to the nipple or the outer part of the breast. Sometime there is pain associated with the lump or abnormal of the outer skin to give a clue that something is wrong but not always does the individual feel the pain or discomfort as the first sign. Another sign can be discharge (clear or bloody) from the nipple of the breast. The changes in the breast are due to that tumors grow without the normal support of the connective tissue. Unfortunately, breast cancer does not stay within t he means of the breast. Breast cancer can spread to the bones, the liver and the lungs. This horrible cancer and the painful treatment alone, weakens the immune system. When the cancer metastasis to the bones, and with the persons weaken immune system, the bones can easily be broken and hard for healing. If the cancer metastasis to the lungs, the person can develop difficulty in breathing, a persistent cough can develop and even pneumonia. Lastly, if the cancer metastasis to the liver, the person can develop abdominal pain, jaundice and problems with clotting of the blood (Mayo Clinic 2018). Some of the symptoms other than soreness of the breast can be but not limited to, extreme fatigue, nausea, no appetite, lack of energy and weight loss. Diagnosis In most cases accurate breast cancer diagnoses is done through a diagnostic exam from a physician. The most classic symptom from early detection of breast cancer can be finding a lump in the breast or armpit. At the present time breast cancer remains unexplained. It is important to know your family health history as of can play a important roll in your health and help the physician. First degree relatives, (Mother, sister, daughter) are most important in estimating risk. Several second-degree relatives (grandmother, aunt) with breast cancer may also increase risk (Wiseman, 2000). Treatment With the treatment and early detection in today’s medicine, breast cancer survival rate has dramatically increased, Chemotherapy is linked to reducing the recurrence of cancer and it’s deaths by a little under fifty percent (Davis 2016). There are two surgical procedures that can be done. The first being a lumpectomy (removal of only the lump) and the other being a mastectomy (removal of entire breast). After the surgeon has done the procedure he will decide if radiation (high energy x-ray or gamma rays, which target a tumor or post-surgery tumor) or chemotherapy is needed. The purpose of chemotherapy is to destroy cancerous cells that are present. Chemotherapy is often given in cycles, a treatment for a period of time, followed by a recovery period, then another treatment can be administered before surgery to shrink the tumor and sometimes make the breast conserving surgery possible rather than a mastectomy (Howell 2014). Conclusion Breast cancer is painful and a individual can suffer long term effects. My dear friend still suffers from weaken bones, nerve damage and breathing difficulties. The last report when she reported back to MD Anderson Clinic was a answer to prayer, no cancer cell noted. In the 1960’s, only thirty-five percent of women diagnosed with breast cancer in the United States would have been alive ten years later, by the mid 1990’s that figure was seventy-seven percent and today the percent is even higher (Grayson 20120. With each day, researchers are finding more to help with higher survival rates. Since we can not control our age or our genetic make-up, we can practice other preventions of breast cancer. A person can practice in their day to day life style to maintain a healthy weight, limit the fat in your diet, limit alcohol consumption and see you physician at least once a year for a complete check-up. Until there is a sure cure people will still lose their life to this dreadf ul disease. Spreading the word and financial support can help paved the way for a brighter future for our children and grand-children. I am so thankful that God allowed the survival of my life long friend. We have known each other since we both were in diapers. I cannot image this world without her glowing personality, beautiful smile and sweet friendship. She has truly blest not only me but everyone she comes in contact with. ? References Star, Biology Life Science, 11th Edition(custom) Ricks, D. (2005).
