Explore the Basic Fundamentals of Physics
Explore the Basic Fundamentals of Physics Physics is a systematic study of the natural world, particularly the interaction between matter and energy. It is a discipline that attempts to quantify reality through a precise application of observation coupled with logic and reason. In order to make use of such a discipline, you must first understand certain fundamentals. Only by learning the basics of physics can you build upon it and dive deeper into this field of science. Whether you are pursuingà a career in physics or merely interested in its findings, it certainly is fascinating to learn about. What Is Considered Physics? To begin the study of physics, you must first understand what physics actually means. Understanding what falls within the realm of physics- and what does not- helps focus the field of study so you can formulate meaningful physics questions. Behind every question in physics lies four very important termsà you will want to understand:à hypothesis, model, theoryà and law.à Physics can be either experimental or theoretical. In experimental physics, physicistsà address a scientific problem using techniques such as the scientific method in an attempt to prove a hypothesis. Theoretical physics is often more conceptual in that physicists are focused on developing scientific laws, such as the theory of quantum mechanics.à These two forms of physics are related to each other and connected to other forms of scientific study. Quite often, experimental physics will test the hypotheses of theoretical physics. Physicists themselves can specialize in a variety of fields, from astronomy and astrophysics to mathematical physics and nanotechnology. Physics also plays a role in other fields of science, such as chemistry and biology. The Fundamental Laws of Physics The goal of physics is to develop precise models of physical reality. The best case scenario is to develop a series of very fundamental rules to describe how these models function. These rules are frequently called laws after they have been used successfully for many years. Physics is complicated, but it does fundamentally relyà on a number ofà accepted laws of nature. Some are historical and groundbreaking discoveries in science. These includeà Sir Isaac Newtons Law of Gravityà as well as his Three Laws of Motion.à Albert Einsteins Theory of Relativityà and theà laws of thermodynamicsà also fall into this category. Modern physics is building off those monumental truths to study things such as quantum physics which explores the invisible universe. Similarly, particle physics seeks to understand the smallest bits of matter in the universe. This is the field where strange words like quarks, bosons, hadrons, and leptons enter the scientific dialogue that makes headlines today. The Tools Used in Physics The tools that physicists use range from the physical to the abstract. They include balance scales and laser beam emitters as well as mathematics. Understanding this wide range of tools and the methods for applying them is essential to understanding the process that physicists go through in studying the physical world. The physical tools include things likeà superconductorsà and synchrotrons, which are used to create intense magnetic fields. These can be applied in studies like the Large Hadron Collider or practically in the development of magnetic levitation trains. Mathematics is at the heart of physics and is vital in all fields of science. As you begin to explore physics, fundamentals such as using significant figuresà and going beyond the basics of the metric system will be important. Math and physics go much deeper as well and concepts like vector mathematicsà and the mathematical properties of waves are crucial to the work of many physicists. Historys Famous Physicists Physics does not exist in a vacuum (even though some physics is practiced in an actual vacuum). The forces of history have shaped the development of physics as much as any other field in history. Quite often, it is useful to understand the historical perspectives which led to our current understanding. That includes the ââ¬â¹many incorrect paths that were faltered along the way. It is also useful and intriguing to learn about the lives of the famous physicists of the past. The ancient Greeks, for instance, combined philosophy with the study of natural laws and are particularly known for an interest in astronomy. In the 16th and 17th centuries, Galileo Galilei further studied, observed, and experimented with the laws of nature. Though he was persecuted in his time, he is regarded today as the father of science (coined by Einstein) as well as modern physics, astronomy, and observational science. Galileo inspired and was followed by famous scientists like Sir Isaac Newton, Albert Einstein, Niels Bohr, Richard P. Feynman, and Stephen Hawking. These are just a few of the names of physics history that have shaped our understanding of how our world works. Their abilities to challenge accepted theories and devise new ways of looking at the universe have inspired physicists who continue to achieve scientific breakthroughs.

PUSH essays
PUSH essays Pushy by Sapphire is a novel spoken through the voice of Claireece Precious Jones dealing with her experiences in the two major classrooms, one being her family setting and the other her education experiences. The novel contains many graphic descriptions of many touchy subjects including sexual abuse, AIDS, welfare, illiteracy, domestic violence, and the educational system. Claireece, or by her own demands Precious lives in Harlem, NY around the early 1980s. She talks about her relationships with her mother and father. These experiences that were never positive scar her for the rest of the novel and her life. It all basically started about the age of two where her mother and father were having intercourse and he reached over towards Precious and started to sexually abuse her. Shortly after this incident her mother as well began to start the abuse. Her mothers and fathers abuse was just like a one night stand but in fact was repetitive along with the demands of having to take care of house hold chores of cooking, cleaning, etc. At the age of twelve Precious gave to birth to a baby girl on the kitchen floor. Who was the father? Yes, sadly enough it was her father. The baby was born with Down syndrome and was referred to as lil mongo. Then at the age of 16 another child yes again by her father. The Childs name was Abdul. Lil mongo was taken care of by P reciouss grandmother but her own mother was getting welfare for supposedly taking care of both the new born and Precious. Shortly after Abduls birth Precious tells the truth to social services and lil mongo is then placed into a special home. This then causes Precious to leave her mothers house where she then finds residence in a home for young mothers and their children. Eventually, her mother comes to the house and tells her that her father had passed away and that he had HIV, which then was passed along to Precious via the sexually abuse. In the educational setting of Push,...

Social Class and Gender Essay Example | Topics and Well Written Essays - 1500 words
Social Class and Gender - Essay Example Question 1-Movie and Gender Gender issues come out clearly in the movie. The interactions between the various characters and the roles given to them bring out the gender relationships. Mrs. Tuohy is an extremely strong woman in the movie despite her being a female. She is also highly demanding as she heads her household and controls all the decisions made in the family. This portrays changing gender roles in the family, where women have gained ultimate control and ability to make vital family decisions. The changing authority and roles of women clearly comes out in the movie when Mrs. Demands that they go back and help Big Mike. She even offers him a place to sleep at their home (Lewis 18). In relation to the course materials from the gender lectures, Mrs. Tuohy shows that women have the capacity to give out orders just like men. On this regard, therefore, both genders should make decisions in their home. Men should not always dominate as the heads of households. No gender should be superior to the other; all should have equal opportunity and be accorded equal rights (Lewis 22). Mrs. Tuohy represents a typical modern woman, who does not heed to the traditions, which sidelined women and favored men. Her character and actions depict women who have the determination to challenge the status quo in the society. Question 2-Movie and Social Class The issue of social class depicts itself in the movie, with some characters having an elevated social status, while others appear to be in the low social stratum. Michael Oher belongs to the lower social status as his family cannot afford to cater for his education. For many years, during his childhood, Michael was under foster care with various families in Tennessee and Memphis (Lewis 30). He runs away whenever placed in a new home. On the other hand, the Tuohys can be regarded as influential and belonging to the upper social class/status. They live in a beautiful mansion. Besides, the friends of the Tuohy family have riches and property similar to that of the Tuohys. In relation to the lecture notes, the social prestigious status of the Tuohy and the lower social of Michael Oher depict the differences in social status. Further, this portrays the vast differences between the poor and the rich in the society. The rich, wealthy, and influential members of the society can be able to afford a luxurious and a happy, desirable life. On the contrary, the poor have difficulties affording to cater for the basic needs of shelter and education. The fact that the families surrounding the Tuohys have a lot of wealth depicts the existence of strong links and networks among the rich (Lewis 35). In the beginning of the Movie, Mrs. Tuohy nearly gets influenced by her friends, who discourage her not to adopt Michael. The Friends argue that the decision to adopt Michael would negatively influence SJ, Tuohyââ¬â¢s son. This shows how the wealthy view the poor as deviant and having undesirable morals. Moreover, when Mich ael goes back to interact with his family and friends, the community appears as poor African Americans who engage in criminal activities as gangs. Question 3-Movie and Race/Ethnicity Scenes from the Blind Side depict the relations that exist between the characters based on their racial and ethnic affiliation. The Tuohys, who belong to the white race, live a prestigious life, while Oher has gone through numerous challenges in life. Racial stereotyping is represented when the family friends
