When the term tea culture comes up, people usually think of places like Japan, China, or England, though perhaps Afghanistan deserves to be in this lineup too. While not as well known as those already mentioned, Afghanistan’s tea culture is a venerable one that dates back centuries. As with many ancient cultural artifacts, tea came to Afghanistan by way of the Silk Road, likely via merchants going to or from China. This tradition continues to this day, as while the country does grow some of its own tea, the majority of Afghanistan’s tea consumption relies on imports from China and Pakistan.
Fundamental conversations, on freedom and self-determination, greatly influenced Anthony Burgess’ choice of immoral characterization and dramatic plot development in his 1962 dystopian novel A Clockwork Orange, dealing with what it means to be able to make choices in a restrictive society and dabbling in themes of freedom and bondage.
Modern-day democracies across the globe continue to thrive as world powers as a result of the choices made by its citizens. However, when governments suppress the voice of the people, as seen in A Clockwork Orange’s totalitarian government, growth is stunted and the government remains static. Similarly, philosophers have debated whether individuals have free will and the extent to which this self-sufficiency extends. Alvin Plantinga, an analytic professor at the University of Notre Dame describes the ability to choose as, “Now, God can create free creatures, but he can’t cause or determine them to do only what is right. For if he does so, then they aren’t significantly free after all; they do not do what is right freely.” (Plantinga). Plantinga’s attention towards the ability to make choices rather than rely on foreordained outcomes reveals the very hypocrisy Burgess aims to reveal through his novel, a hypocrisy centered on the notion that good can’t live without the choice to do otherwise. Alex, who is the antihero of the novel, questions the government which strives to dictate him, wondering, “ What does God want? Does God want goodness or the choice of goodness? Is a man who chooses the bad perhaps in some way better than a man who has the good imposed upon him?” (Burgess). Alex’s internal line of questioning and later entrapment by the restrictive government reveals the evident truth of decision making. Without choice, then there is no moral guideline to follow and, essentially, no discernment from right and wrong. To state that the ability to make a choice through self-autonomy is an act of hypocrisy in and of itself as the individual making such a claim would be referring to their own volition. For example, Jans Jonas, a German philosopher reveals an anecdote about a group of physiologists such as Ernst Brucke and Emil du Bois-Reymond who promised early in their careers, “Brucke and I pledged a solemn oath to put into effect this truth: ‘that no other forces are at work in the organism except chemical-physical ones’” (Jones). Contrary to their statement, their eventual rise to fame is an indicator of the impact personal actions have on an individual. As Seifert, an Austrian philosopher explains,
There is some universal beauty in the harmonies and melodies that dance their way to an ear in weaving sound waves. Music has been an integral part of everyday life since the glorious sounds of 500 BCE Ancient Greece and Rome. In the last few decades, the industry has grown to encompass over a thousand different genres and continues to expand and evolve alongside the world. Many recognize music as a reflection of their mood: upbeat to go along with a night out with friends, mellow to accompany the endless waterworks, or maybe rock and roll to fit a certain rebellious phase of life. However, behind the curtain, music can work all forms of magic on the mind. In fact, listening to music can increase cognitive performance, stimulate pain reduction, and promote stress relief.
In recent years, the labels of “fake news” and “the enemy of the people” have been prevalent when talking about the media, especially from the White House. The hostile rhetoric from Washington has had a considerable impact on the public: Americans’ trust in mass media is at 41%, a significant 4% drop from the previous year. Additionally, partisanship has dramatically increased as many Americans opt to solely consume news media that perpetuate their beliefs, leading news companies to produce blatantly partisan content, and thus, further promoting partisanship among their readers. This cycle creates an echo chamber that results in a sharply divided and often misinformed population.
In this article, Infinite limits are limits that evaluate to infinity. You can, however, have limits that are evaluated at infinity or have an evaluated value of infinity. While infinity is a strange concept, we can use it to determine the behavior of functions. This leads us to the discussion of infinite limits and limits at infinity.
In the last two articles, we talked about limits and their application in determining the continuity of a function. Here, we will apply those skills to few practice questions. Attempt the problems on your own at first; however, if you get stuck, the solution to each problem is just below it. These problems vaguely range from easy to hard. Enjoy!
In this study guide, we review anemia, types of anemia, formulas, vocabulary, heme breakdown, and anemia of chronic diseases.
In this chapter, we will introduce the first big idea in AP Calculus: Limits and Continuity. This a topic that is included in both the AB and BC Calculus courses. Even if your course hasn’t started yet, a good way to prepare yourself for it is to study limits, as they are generally easy to grasp. This will give you a head start on (most likely) the first topic you will learn in your AP calculus course, and can inhibit you from falling behind.
In this calculus article, we will talk about the methods for actually solving or evaluating limits. There are practice questions included, labeled PRACTICE, and they are there for you to test your understanding of the different methods. The answers are at the very bottom. Enjoy!
What happens when you put good people in an evil place? Does humanity win over evil, or does evil triumph? Philip Zimbardo, a psychologist and a professor at Stanford University posed the same exact question in 1971, thereby leading to what is known as The Stanford Prison Experiment (SPE). The experiment was originally created to uncover the truth about human nature, a more in-depth look on what our true ambitions were, what really drove us. Zimbardo began by choosing 24 volunteers, making 12 of them “guards” and the other 12 “prisoners”. They were taken to a prison simulation, a fabricated illusion to make the volunteers feel as if they were actually in prison. He began by giving the guards ultimate power and left the prisoners vulnerable. This evidently led to a distinction of power between the two groups. 45 years later, people still ponder the question that drove the experiment to its end. Was this study ethically right? The Stanford Prison Experiment was not ethically right, it stripped volunteers of emotion temporarily, forcing them to turn against each other and was physically harmful to the majority of the participants.
A huge thank you to all the teachers around the world! May 3 is Teacher Appreciation Day, also known as National Teachers Day, and Teacher Appreciation Week lasts from May 2 – May 6. Teachers are invaluable to our communities. They nurture the growth of our students, both young and old, and inspire us to succeed with the gift of learning and education.
B-Cell Development Stages. stem cell –> early pro-B cell –> late pro-B cell –> large pre-B cell –> [1st checkpoint – selects for functional heavy chains] –> small pre-B cell –> [2nd checkpoint – select for functional light chains] –> Immature B cell (has surface IgM, no surface IgD). Somatic recombination is the process in which different individual gene segments of the H (heavy) chain combine with rearranged gene segments of the L (light) chain. The enzymes responsible for somatic recombination are the recombinase enzymes (RAG-1 and RAG-2) that recognize specific sequences (RSS) or recombination signal sequences. RAG-1 and RAG-2 are only expressed in B or T lymphocytes. These specific sequences recognized by the RAG-1 or RAG-2 enzymes are either a 1) heptamer or 2) nonamer. The heptamer literally contains 7 nucleotides, and the nonamer literally contains 9 nucleotides. There are typically 12 or 23 nucleotides in between the heptamer and nonamer to separate them.
In the midst of the COVID-19 pandemic, many people have been forced to quarantine themselves in their homes. Although countries are starting to open and people are exiting quarantine, social distancing is still common and previously planned summer activities such as trips, internships and summer jobs have been postponed or cancelled. With summer having arrived, students will no longer be distracted by their classes. This raises the question, what can we do over a quarantined summer?
