The Art of Studying Smart

Most of the world tends to look down upon the idea of procrastination with a frown. She’s lazy. She’s not responsible. She doesn’t have a work ethic. My view of this concept is slightly different. I wish I could slip back into my elementary school days as a model student, but I’m barely learning yesterday’s content by the time tomorrow rolls around. My stress levels and recent academic performance, on the other hand, tell an entirely different story. Procrastination might not be for everyone—some people need rigid schedules for their personal sanity and success, and these individuals should be held in high regard. For the rest of us: if we learn how to properly procrastinate, we could have all the success and time in the world. In fact, there are three simple steps to embracing the art: always keeping the task in the back of your head, being able to self-discipline when it’s time to work, and knowing your personal capabilities and limits.

The Power of Music and its History

“Scientists have found that music stimulates more parts of the brain than any other human function.” These are the words of Elena Mannes in her book, The Power of Music. Music has had significant impacts on communities throughout history and evidently remains influential today through its cultural effects on society and scientific effects on the individual brain. 

Music has essentially existed since the beginning of history. Although extremely different from what comes to mind when thinking about music today, it has been representative of many different cultures, religions, societies, and events throughout centuries. 

The history of music begins as early as Medieval times when music had emerged in society through the influence of the power of Roman Catholic churches. The Medieval period was the longest period of music in history and ran between the years 400 and 1400. This music was largely monophonic meaning there was a single melody to each piece of music. Gregorian chant, which would have a single line of vocal melody, was a very common type of music during this time which was heavily influenced by the Church. As the Medieval times evolved, monophonic music eventually turned into polyphonic music with multiple melodies. When the Catholic Church wanted to unify the Church music across the Western world, music notation was first created and documented so people could share and play the same music. Instruments that characterized the music of this era include wooden flutes and wooden string instruments including the first bowed instruments such as the Lyra.

Psychology 101: Emotions – Why Do We Feel the Way We Do? James-Lange Theory vs Cannon Bard Theory vs Two-Factor Theory

When we are met with sudden bursts of emotions, what comes first: the physical or mental reaction? 

Since the inception of psychology, emotions have turned into an interesting chicken or the egg phenomena. When good things happen, we smile, but does smiling make us happier? 

In the world of psychology and motor neurons, these questions remain unanswered, but countless theories have arisen to explain this almost unexplainable human characteristic. These theories have tried to distinguish the specific firing point within our bodies regarding these emotions, but all of them lack an explanation broad enough that can effectively describe such a diverse human race. 

Emotions are a complex mixture of our physical, cognitive, and expressive behavior, but to what extent do each of these matter? Of course, when good, positive things happen to us, we feel a gut-reaction, whether that be smiling or laughing. All of these reactions happen both beneath our skin and within our neurons while also being presented outward and physically.

History of Tea and Modern Afghan Tea Culture

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.

Literary Analysis: An Examination of Free Will Through Anthony Burgess’ A Clockwork Orange

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,

The Magic of Music: History, Cognitive Boost, and Music in Medicine

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.

Mass Media vs Local Journalism: A Pillar of American Democracy

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.

Calculus: Infinite Limits vs Limits at Infinity with Explanations, Practice Questions, and Answers [AP Calculus, Calculus 101, Math]

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.

Calculus: Limits vs Continuity with Explanations, Practice Questions, and Answers [AP Calculus, Calculus 101, Math]

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!
