Free Essays on Steve Hawking

Dr. Stephen Hawking has been considered to be more brilliant then Einstein. Dr. Hawking was born on January 8 1942 in Oxford, England on the 300th anniversary of Galileo’s death. Is this a coincidence? After his studies at St. Albans School, he attended University College, Oxford. He wanted to study Mathematics, but because it was unavailable at Oxford, he concentrated on Physics and earned a degree in Natural Science three years later. Stephen went on to Cambridge to do research in Cosmology. After attaining his Ph.D., he became a Professorial Fellow at Gonville and Caius College. He left the Institute of Astronomy to become a professor at the Department of Applied Mathematics and Theoretical Physics at Cambridge. He has held the post of Lacasian Professor of Mathematics since 1979. In the early 1960’s, Stephen Hawking was diagnosed with the dreadful disease Amyotrophic Lateral Sclerosis (A.L.S.), an incurable degenerative neuromuscular disease, also known as Lou Gerhi g’s Disease. He has been paralyzed unable to use every muscle in his body. The only muscles he has use of are those around his eyes. This explains why Hawking has become a theoretician rather than a â€Å"hands-on† scientist. He spends hour after hour in his wheelchair pondering complex ideas and formulating mind bobbling equations in his head. Dr. Hawking’s work is primarily in the field of general relativity and in particular on the physics of black holes. He uses his theory on the origin of black holes to help explain the creation of the universe. In 1971 he suggested the formation (following the big bang), of numerous objects containing as much as 1,000,000,000 tons of mass but occupying only the space of a proton. These objects, called mini- black holes, are unique in that because of their immense mass and gravity, they are ruled by the laws if relativity, while their minute size requires that the laws of quantum mechanics apply to them also.

Diapause - Definition of the Term Diapause

Diapause - Definition of the Term Diapause Diapause is a period of suspended or arrested development during an insects life cycle. Insect diapause is usually triggered by environmental cues, like changes in daylight, temperature, or food availability. Diapause may occur in any life cycle stage – embryonic, larval, pupal, or adult – depending on the insect species. Insects inhabit every continent on Earth, from the frozen Antarctic to the balmy tropics. They live on mountaintops, in deserts, and even in the oceans. They survive frigid winters and summer droughts. How do insects survive such extreme environmental conditions? Â  For many insects, the answer is diapause. When things get tough, they take a break. Diapause is a predetermined period of dormancy, meaning its genetically programmed and involves adaptive physiological changes. Environmental cues arent the cause of diapause, but they may control when diapause begins and ends. Quiescence, in contrast, is a period of slowed development that is triggered directly by environmental conditions, and that ends when favorable conditions return. Types of Diapause Diapause can be either obligatory or facultative: Insects with obligatory diapause will undergo this period of arrested development at the predetermined point in their life cycle, regardless of the environmental conditions. Diapause occurs in every generation. Obligatory diapause is most often associated with univoltine insects, meaning insects that have one generation per year.Insects with facultative diapause undergo a period of suspended development only when conditions require it for survival. Facultative diapause is found in most insects and is associated with bivoltine (two generations per year) or multivoltine insects (more than two generations per year). Additionally, some insects undergo reproductive diapause, which is a suspension of reproductive functions in adult insects. The best example of reproductive diapause is the monarch butterfly in North America. The migrant generation of late summer and fall goes into a state of reproductive diapause in preparation for the long journey to Mexico. Environmental Factors That Trigger Diapause Diapause in insects is induced or terminated in response to environmental cues. These cues may include changes in the length of daylight, temperature, food quality and availability, moisture, pH, and others. Â  No single cue solely determines the start or end of diapause. Their combined influence, along with programmed genetic factors, controls diapause. Photoperiod – A photoperiod is the alternating phases of light and dark in the day. Seasonal changes to the photoperiod (such as shorter days as winter approaches) cue the start or end of diapause for many insects. Photoperiod is the most importantTemperature – Along with photoperiod, changes in temperature (such as an extreme cold spell) can influence the start or end of diapause. The thermoperiod, alternating phases of cooler and warmer temperatures, also influences diapause. Some insects require specific thermal cues to end the diapause phase. For example, the woolly bear caterpillar must endure a period of chilling to trigger the end of diapause and continuation of the life cycle.Food – As the growing season ends, the diminishing quality of their food sources may help trigger a diapause phase in an insect species. As potato plants and other hosts turn brown and dry, for example, Colorado potato beetle adults will enter a state of diapause. Â   Sources: Encyclopedia of Entomology, 2nd edition, edited by John L.

Self awareness assignment Essay Example | Topics and Well Written Essays - 1500 words - 1

Self awareness assignment - Essay Example Oakes et a defined self-esteem as â€Å"emphasize efective self-regard . . . feeling of affection toward neself (779). Others define it as an overall judgment one makes about one’s worth as a person. But regardless how it is defined, self esteem includes affective and cognitive components. â€Å"High self esteem people feel good about themselves and think they have many positive qualities† (779). On the reverse, low self-esteem people hold ambivalent feelings toward themselves and are less certain that they have many certain positive qualities (Baumeister, Tice & Hutton, 1989 qtd in Oakes et al 779). To this, Anjala and Worthen added the specifics of body image and self image which comprises self-esteem (90) Inferring from these definitions in setting up a SMART Goal in developing my self esteem, I will initially target a 20% increase in positive self esteem, progressing to 40% in the second week, 60% in the third week and 80% increase in self-esteem the fourth week of assessing the development of my self-esteem. The SMART Goal is effective because it is grounded on reality and the parameters were conservative. It is not an overly optimistic goal that is difficult to achieve that would make one eventually abandon the plan. Rather, it is composed of step by step plan that only requires realistic efforts that could be done consistently. Inferring from the definition of Oakes et al and and Anjala, I will categorize the componenets of self esteem as internal and external. Internal are those whom Oakes said to feel good about myself and which is triggered by a positive stimuli that helps us cope positively with the challenges of life(Tariq 23). To achieve these goals I will engage in activities that are consistent with the internal and external components about self esteem. With regard to the internal factor of feeling good about myself, I will begin making more friends and spending more time with family

Teaching Special Groups - Coursework Example Tutor Signature: Date: Table of Contents Table of Contents 3 Task 1 4 Task 2 5 Task 3 6 Task 4 7 Task 5 8 Task 6 9 Task 7 11 References 12 Task 1 List the different categories of beginner students, giving a brief explanation of each: Answer 1: There are different categories of beginners students, this includes: The absolute beginner’s students are those who do not have any knowledge of English language. This may include the small children’s, students from abroad or people speaking language other than English (Davison and Dowson 2003). The false beginners are those who have a little knowledge of the English language as they were previously thought English, but do not have proper knowledge. As they are only able to make few simple structures in English language. The adult beginners are those who can have made their own decision related to learning English language and are highly motivated for learning it (Davison and Dowson 2003). The young beginners are those who are una ware of the benefits of learning English and also lack motivation as they just have made the choice to learn the subject. These learners are fast and grab the language more easily than the adult beginners. Beginners devoid of Roman alphabet: These students need a lot of personal attention and also need a lot of initial working on their basic skills related to the literacy. They also require a lot of reading and writing exercises for making them learn the language (Davison and Dowson 2003). Task 2 How would you as a teacher adapt your approach to beginner students? Answer 2: As a teacher for the beginner students the needs of students will be initially identified as why the learning of the language is important for them and make clear and realistic aims for them. I will adopt the methodology to that will suit the situation the most for the students. The classroom will be arranged in a manner that will highly benefit them in learning English language using many visual which will aid t hem in learning (Davison and Dowson 2003). I will also take care of the board work which includes the justification of simple and clear instructions. The lessons to be given to them will be of appropriate pace in order to make them comfortable in learning. The practices provided will also be repeated in appropriate interval in order to make them learn the practices. Lots of questions will be asked to them in order to clear all their doubts and also to make them remember the learning’s (Osborne 2005). The students will also be encouraged to speak English in class in order to make them familiar with the language and make them revise the lessons in a proper interval. The students will also be assigned with appropriate homework’s which will assist them in learning the language on a continuous basis and make them learn the language perfectly. Task 3 How can teaching individual students differ from teaching groups? Answer 3: There is a large difference in between teaching in dividual students and teaching students in groups. Teaching individual students have a number of advantages and disadvantages as compared to group teachings. As in the individual teaching the students are highly motivated as compared to students in groups, and the needs of individual students can also be easily defined as compared to the groups. In individual learning the teacher builds up a close relationship with the student as compared to the group’s teachings (Osborne 2005).

Habitat for Humanity Essay Example for Free

Habitat for Humanity Essay Habitat for Humanity originated at Koinonia Farm, which is a small Christian farming community located outside of Americus, Georgia. Clarence Jordan brought the idea to Millard Fuller, who is the founder and president of Habitat for Humanity International. They developed the idea of â€Å"partnership housing,† calling for families in need of a home to partner with volunteers to build affordable homes. In 1975 Fuller and his wife Linda established Habitat for Humanity with one clear vision in mind â€Å"a world where everyone has a decent place to live. † Habitats ministry is based on the conviction that to follow the teachings of Jesus Christ we must reflect Christs love in our own lives by loving and caring for one another. Our love must not be words only – it must be true love, which shows itself in action, this is the full forces that lead Fuller and his wife to establish this organization. Habitat provides an opportunity for people to put their faith and love into action, bringing diverse groups of people together to make affordable housing and better communities a reality for everyone. The idea of Habitat for Humanity is to work in partnership with God and people to build decent, affordable, houses in which people can live and grow into all what God has intended. The Fuller’s vision has become a successful reality that has presently helped build over 500,000 homes and helped over 2.5 million people worldwide. Habitat for humanity is operated based on two main sources: donations and mortgage payments of the homeowners. Donations generate from individuals, foundations, and businesses their monies are used to purchase land and materials. The no-interest mortgage payments made by current Habitat homeowners greatly contribute to support the construction of additional Habitat homes. Some organizations such as Ameri-Corp may pay their volunteers with school courses and materials in return for their time. Habitat for Humanity’s crucial point is not just to build a house and help people to be under a roof, but their main goal is to build a clean, decent, and stable house for families: these families can provide stability to their children, the sense of dignity and pride grows for these families; health, physical safety, and security improves, educational and job prospects. My experience at Habitat for Humanity was a powerful and passionate one. Amazingly, one of the most precious gifts we can give one another is – time. A couple of hours or days can translate into a lifetime of hopefulness and commitment to strive and I had the opportunity to experience this reality, throughout my experience at the Habitat. I have learned what the meaning of passion is mainly because I’ve had the genuine sentiment to finish the work I’ve started, along with many other people that shared this experience with me. The other thing that I discovered about passion is how easy it is to be a family with people you have met for the first time if you open your heart to them and let them be part of your life. The other thing I found about passion is the skills that I have that would help to repair the universe. In this experience I found something that has deepened my faith that God created each one of us uniquely with specific skills that not everybody has; therefore, this experience helped me to find skills that I am going to use to help building the world again with passion and also the experience and realize that the simple usage of my hands can a the life of a family. The people that I met at Habitat for Humanity were dedicated to their jobs. As I approached the job site, I noticed several groups of people who were putting their time and organization into this home-building project. They invested hundreds of hours of sweat into building houses to help low income families. Some days, community volunteers spend more than eight hours working on the houses. To complete their jobs, volunteers overcame obstacles such as: lack of supplies, unusable wood, and lack of enough workers. The employees and volunteers I met were motivated to overcome obstacles to help families in need. Though they may not have had the best materials, they used what they had in order to complete the job. Many of these materials come from the Re-Store; this store sells donations mostly given by the community. The funds collected are used for materials and other services that are required. Volunteers must be willing to work in the heat and endure a lot of intense physical labor. Wall-framing, installing dry wall, plumbing and roofing are skills that the organization needs from volunteers. The volunteers I worked with were willing to endure the heat and physical labor in order to help low income families who need a home. If you are looking for a place where you can make a huge impact on society, Habitat for Humanity is the place. People of all backgrounds, races, and religions are invited to build houses for people in our community. Habitat for Humanity is capable of working with each volunteer’s skill level. Don’t be afraid of hard work. No matter what goes on in your life, you will always remember all of the positive things you have done to help out in your community. In conclusion, Habitat for Humanity does such essential work and by that work they recognize the concept of passion and Christianity, and the other thing about them is they recognize that there are needs in the world and these needs should be met with their work. My experience helped me change my idea about service and the real meaning of service, and it let me be familiar with the big three R’s- restoration, reparation, and reconciliation that are the keys for service. The three R’s were spoken among many of the volunteers that I met, indeed the R’s simply describe this experience, the other thing I found is that dedicating myself is another important part of service because without dedicating myself, the work that we need to do to repair the universe would not be as perfect as how it should be.

Exodus and the Ethics of Labor Essay -- Social Issues, Oppression

Oppression is something that has been repeated throughout history all over the world. Whether it was the oppression of Black Americans during the Jim Crow period or the oppression of Jews in Nazi Germany during World War II, oppression is an unethical act that humanity has not yet moved past. Looking to the Bible as a source of Christian ethics in terms of how to fight oppression and promote equality brings to attention how God intended His people to be treated, especially the poor and the helpless. The book of Exodus is a primary guide for what the ethics of labor ought to be in the work force to avoid oppression. One might reference the story of the Israelites in the book of Exodus. The Israelites are under the thumb of the Pharaoh and the Egyptians that force them into slave labor. The grueling and overly strenuous labor conditions in which the Israelites are put under is comparable to the labor conditions that the employees of slaughterhouses are forced to endure today, as illus trated by Fast Food Nation by Eric Schlosser. By comparing these two labor conditions, the reader is able to apply the Biblical ethics found in Exodus to modern times. â€Å"Knocker, Sticker, Shackler, Rumper, First Legger, Knuckle Dropper,† these are just a few of the positions the workers at a slaughterhouse get assigned to. Simply reading the names of the above job positions induces a sense of nausea and hints at the inherent brutality that these positions demand (Schlosser, 172). Because the weight and size of cows is unpredictable, most of the labor in the slaughterhouse must be done by hand. On the kill floor of a slaughterhouse, workers are forced to slice cattle into halves with a power saw â€Å"as though they were two-by-fours,† (Schlosser, 170). Wo... ...is people to be free and live and work under ethical and just conditions. Jesus preaches that as long as the Israelites follow his commandments, they will be â€Å"treasured among all people† and that they will live in a â€Å"land of milk and honey,† (Exodus 3:8). Unlike the unethical laws that the Pharaoh forced upon the Israelites, Jesus’s commandments are moral and promote the common good of the whole community. The Bible says in Exodus 1:12, â€Å"But the more they were oppressed, the more they multiplied and spread.† This provides hope the workers in the slaughterhouses whom are still forced to work under unsafe conditions today. The workers must become collectively active and speak up and fight for their right to an ethical work environment. Ultimately, the minorities and immigrants will become the majority, and the â€Å"dictators† of the world will be forced to step down.
