In this blog post, we’ll examine the principles behind sinkholes and ground subsidence—where the ground suddenly collapses—as well as their natural causes and those arising from urban development, and explore corresponding preventive measures. A Bolt from the Blue on Dry Land: Sinkholes Back in 2012, the ground collapsed like a bolt from the blue. Near a construction site for the Incheon...
In this blog post, we’ll explore what plastic surgery means in a society where physical appearance is seen as a competitive advantage, and how we can view the pursuit of beauty and societal perceptions of plastic surgery. There’s a saying: “If the price is the same, choose the better option.” This means that if two options cost the same, you should choose the better one—a principle that...
In this blog post, we’ll explore how an airplane weighing hundreds of metric tons can fly, understand the principles of flight through the lift generated by the wings, and examine the flaws in the commonly held “long-path theory.” When I lie in bed scrolling through Facebook before sleep, I’m constantly seeing a flood of photos posted by friends from their overseas trips—featuring blue...
In this blog post, we’ll explore the principles behind how airplanes—including the massive A380 passenger jet—fly, and examine how lift is actually generated by debunking the commonly held misconceptions surrounding Bernoulli’s principle and the “equal-time theory.” “Where dreams are made. The A380, the airplane of dreams.” This was the advertising slogan used by Korean Air when it first...
In this blog post, we’ll explore the principles, structure, pros, and cons of Gore-Tex—which blocks rain while allowing sweat and water vapor generated by the body to escape—as well as recent technological advancements. Have you ever gotten soaked in sweat while trying to stay dry in the rain? Imagine walking in a raincoat on a rainy day. It’s raining, but it’s hot, so you start to sweat...
In this blog post, we’ll explore how the “Bung Bung Drink” works in our bodies and the effects of caffeine on the human body. Have you ever heard of “Bung Bung Drink,” which recently became a trend among middle and high school students?

In this blog post, we’ll explore ways to solve the free-rider problem that arises in group projects by examining the evolutionary process behind altruistic behavior in humans, and based on that, we’ll reflect on what it means to live righteously. “I’m not feeling well today, so I don’t think I can make it,” or “Something came up at home, so I’m out.” If you’ve ever worked on a group...
In this blog post, based on the movie ‘Gattaca’, we’ll explore how the creation of “designer humans” might affect human free will, happiness, and the meaning of life. The Choice Between “Designer Humans” and “Natural Humans” Vincent, from the movie ‘Gattaca’, was born out of his parents’ love. However, a genetic sequencing test conducted immediately after his birth...
In this blog post, we’ll examine the differences between custom-made humans—who could be created through genetic engineering—and natural humans, and we’ll explore the implications of likening custom-made humans, who overcome genetic limitations, to “natural humans wearing glasses.” In the popular weekend drama “Passion,” the main character discovers through a paternity test that he is...
In this blog post, we will examine the potential of personalized human technology to prevent diseases and disabilities and improve the quality of human life, as well as the social and ethical issues that may arise in the process, and consider how this technology should ideally be utilized. In the early 2000s, when Professor Hwang Woo-suk’s research team garnered worldwide attention for...
