Aristotle believed that happiness was the ultimate goal of human life. We often comfort ourselves by saying that wealth does not guarantee happiness, especially when money is tight. But is that really true? How much wealth do we actually need to feel happy? Psychologist Professor Eun-guk Seo suggests that Aristotle’s view is just a personal perspective—not a scientifically proven fact. He explains that, in nature, survival is the primary goal, and happiness is more of a tool for survival than an end in itself. So why do we work hard and strive to earn money, even in tough times? While money may not guarantee happiness, it can help us live more comfortably. In the end, economic activity is about survival—if we can’t meet our basic needs, it’s hard to enjoy happiness or convenience. - Joseph’s “just my thoughts”
The reason pencils can be writing instruments is due to pencil lead. The material used for pencil lead is graphite. The graphite element is carbon (C), and four carbon atoms are combined. One carbon atom can have four bonds and can combine with another element. Diamond is similar to graphite, with four carbon atoms. However, diamonds have four carbon bonds that create a strong covalent bond with other carbon atoms, while graphite has only one weak bond. We can write or draw with a pencil because of this loose combination. When you apply pressure to the pencil with your finger, this weak bond in graphite breaks, leaving some of the crystals damaged. Don’t view it merely as a pencil; it’s a diamond’s cousin. The degree of consanguinity is very, very close. - Joseph’s “just my thoughts”
