There are a number of examples of decisions that were made in American history that were done to protect the elite class.  Howard Zinn dedicates an entire book on this very topic (A People's History of the United States.)  He begins his narrative with the birth of the United States and how the establishment instigated the conflict with Great Britain in an effort to create more wealth for themselves.  Most of the middling and lower...

There are a number of examples of decisions that were made in American history that were done to protect the elite class.  Howard Zinn dedicates an entire book on this very topic (A People's History of the United States.)  He begins his narrative with the birth of the United States and how the establishment instigated the conflict with Great Britain in an effort to create more wealth for themselves.  Most of the middling and lower classes in the colonies had very little to gain from independence from England.  They were essentially trading one elite group for the other.  For this reason, there was draft violence throughout the colonies as the lower classes were forced to fight this conflict.  He examines every American conflict in the same way:  they are fought to protect the interests of the powerful.  

The use of the American military throughout history to protect the interests of the wealthy needs be discussed when altering the standard narrative. History textbooks generally discuss American wars being fought to protect democracy and freedom around the world.  If you think about American involvement in World War I, it can be stated that American forces were sent to Europe to protect the interests of banks and munitions dealers that were creditors to the Allied Powers.  Congress itself drew the same conclusion in the 1920's (Nye Committee.)  The United States would commit to the same action a generation later in World War II when it instigated Japan to war in an effort to protect financial efforts in China.  The narrative continues into the Cold War and more recently with the War on Terror.  When you examine the acts of the United States through the lens of who benefits from different actions, the answer is usually the "chess players" that you reference in your question.

A convex lens is used in a projector. If the object is located 10 cm from the lens, and the image is projected at 150 cm, what is the magnification...

Magnification is the increase in size of the appearance of an object. It does not increase the object in size, just its appearance to us. When using a convex lens, the magnification of an object is given as:

M = -Di/Do

where M is the magnification, Di is the distance of the image and Do is the distance of the object from the lens.

In this case, the object is placed 10 cm from the...

Magnification is the increase in size of the appearance of an object. It does not increase the object in size, just its appearance to us. When using a convex lens, the magnification of an object is given as:

M = -Di/Do

where M is the magnification, Di is the distance of the image and Do is the distance of the object from the lens.

In this case, the object is placed 10 cm from the lens, thus, Do = 10 cm

Similarly, the image is formed 150 cm from the lens and hence, Di = 150 cm

Using the equation for magnification:

M = - (150/10) = -15

Thus, the object would be magnified by a factor of 15 in this case. A negative sign indicates that the image will be inverted. 

Hope this helps.

I just need help for creating a better thesis statement regarding politics.

I can help you to the degree I am able to give you general advice on thesis statements and on politics.  The kind of essay you are expected to write, for example, an informative essay, an argumentative/persuasive essay, a cause and effect essay, or a compare and contrast essay, is going to affect the nature of your thesis statement.  

But in any event, a thesis statement is meant to make an assertion of your main...

I can help you to the degree I am able to give you general advice on thesis statements and on politics.  The kind of essay you are expected to write, for example, an informative essay, an argumentative/persuasive essay, a cause and effect essay, or a compare and contrast essay, is going to affect the nature of your thesis statement.  

But in any event, a thesis statement is meant to make an assertion of your main idea along with providing the points you wish to make to support that assertion.  For example, you may want to argue that the political process in the United States is a disaster right now.  A thesis statement for such an assertion could look like this:

Politics in the United States at the present time are a disaster, with gridlock in the legislative body, with Americans having less faith in their political institutions than at any other time in history, and with the present presidential campaign being mired in personality and fear, rather than premised upon ideas and policies. 

I have made an assertion here, and then I "list" the evidence I will be using to support that assertion.

If I wanted to have a cause and effect kind of essay, here is thesis statement I might use:

Because of the nature of campaign financing today, campaigns have become orgies of expenditure, rather than full and fair explications of candidates' positions.

I am in that thesis statement asserting a cause and effect, which I will support with evidence in my body paragraphs.

So, your thesis statement is going to depend on the nature of the essay you are expected to write, as well as what it is exactly, that you wish to assert.  I hope this helps you, and as you home in on what your main idea is going to be, we can help you more to refine it.

How can I create a comparative study of breast cancer awareness using newspapers?

Comparative analysis typically refers to comparing and contrasting 2 or more ideas. In reference to your question, your instructor could be asking you to compare and contrast 2 or more newspapers or compare/contrast how newspapers located within 2 different countries/states have brought awareness to breast cancer issues during a specific time frame.  For example, a question could be the following: over the past 10 years, how have Paper A and Paper B covered breast cancer issues or brought awareness to breast cancer issues?

The essay could then discuss how often articles referring to this topic have been published, where in the newspaper have these types of articles been published (front page, health section, etc.), the average length per article, and what topic/issue these articles typically covered (i.e., detection, prevention, treatment, etc.). I would strongly suggest that you contact your teacher and ask him/her to give you more specific information on how to compose this paper. Does your instructor want you to conduct a comparative analysis of 2 or more different newspapers, 2 different publishers, etc.? Would the comparative analysis cover information that has been published during the past 5 years or more? What specific information would your instructor like for you to include/cover within your paper (i.e., information regarding how often certain types of articles were covered)?

Also, you would want to confirm that your instructor would like for you to conduct a comparative study and not compose a comparative essay. The purpose of a comparative study is very similar to the definition of comparative analysis. However, a comparative study is usually a comprehensive overview and would involve a collection/analysis of qualitative and quantitative information. If this is the case, then your study design could be a case study and your approach to analyze the data could be grounded theory. For example, in case studies, researchers collect data using observations, interviews, tests, records, surveys, etc. in order to answer a descriptive question (what is happening or what has happened?) or an explanatory question (how or why did something happen?), or to address how effective an initiative is in producing a particular outcome. Grounded theory refers to your qualitative approach: you develop a theory about a phenomenon of interest. This theory is usually grounded in or developed from observations. In the written report, the sections of a comparative study would typically include an Abstract, Introduction, Literature Review, Methodology, Results/Findings, and Conclusion.

I hope this helps!

For an essay, I have to pick an epigraph from Into the Wild, by Jon Krakauer, which best explains Krakauer's purpose in writing this book. Can...

Krakauer has a number of reasons to write Into the Wild.In the Author's Note in the Anchor Books edition, Krakauer lists a few: he is interested in the "grip wilderness has on the American imagination," in the allure of high risk activities, and in the "highly charged bonds between fathers and sons."

Krakauer has a number of reasons to write Into the Wild. In the Author's Note in the Anchor Books edition, Krakauer lists a few: he is interested in the "grip wilderness has on the American imagination," in the allure of high risk activities, and in the "highly charged bonds between fathers and sons." At bottom, I think Krakauer writes the book to try to understand why McCandless did what he did, and to describe the volitile mixture of extreme self confidence, practical skill, and rampant Romanticism that made McCandless the person he was. But mostly, I think, Krakauer is drawn to McCandless's story because he sees something of himself in Chris. McCandless was a person who had a dream and followed it to the end. So in a way, writing McCandless's biography is a kind of inside way for Krakauer to write about his own need for the wild. Perhaps the book is an expression of Krakauer's own dream.

In regards to the novella Animal Farm, what ways does George Orwell make us think about corruption of power?

Throughout the novella, Orwell depicts how positive ideology can be twisted and manipulated by power hungry individuals. Initially, Napoleon studies and helps create the tenets of Animalism, but shortly after finds an opportunity to usurp power by getting rid of Snowball. Napoleon enjoys receiving special treatment for being a pig and wants to be in control of the entire farm. Napoleon does so by using brute force. He secretly trained several savage dogs in the...

Throughout the novella, Orwell depicts how positive ideology can be twisted and manipulated by power hungry individuals. Initially, Napoleon studies and helps create the tenets of Animalism, but shortly after finds an opportunity to usurp power by getting rid of Snowball. Napoleon enjoys receiving special treatment for being a pig and wants to be in control of the entire farm. Napoleon does so by using brute force. He secretly trained several savage dogs in the loft of the barn to act as his personal assassins and protectors. These dogs strike fear in the animals and force them to accept Napoleon's reign as leader. Napoleon also employs Squealer to spread propaganda which influences the animals to act in Napoleon's favor. Orwell warns his audience that anytime power is consolidated among a small group of individuals, there is a likely possibility that at least one person will become corrupt which could lead to tyranny. Once individuals experience a sense of control and privilege, they can easily become corrupted by the power they possess.
