In this blog post, I’ll explain in simple terms what data compression technology lies behind MP3s and why they allow us to store so many songs on such small devices.   Introduction I still vividly remember the shock I felt when I first saw an iPod box emblazoned with the phrase “1,000 songs in your pocket.” The fact that a palm-sized device could hold so many songs seemed like magic to me...

In this blog post, I will analyze the advantages and limitations that MMORPGs can offer to the study of collective behavior by examining their physical and structural similarities, the projection of player behavior, and real-world examples such as the “Tainted Blood Incident.”   Motivation for Choosing the Topic Since the late 1990s, the development of gaming technology has led to a surge in...

In this blog post, we’ll explain the concept of micro-electro-mechanical systems (MEMS) and its key fabrication processes—lithography and etching—in simple terms.   From cartoon to reality: tiny machines are all around us Anyone who has watched “The Magic School Bus” will remember the children learning about science whilst riding on a bus that could change size at will. In particular, the...

In this blog post, taking the premise of the film ‘The Matrix’ as our starting point, we will establish a few premises and explore the question of which life we would choose between reality and a virtual reality that is indistinguishable from it.   Setting the Scene — The Matrix Dilemma Let us recall Neo’s situation in the film.

In this blog post, we’ll look at what LIBS is and why Curiosity uses it to analyse Martian soil.   What is LIBS? LIBS stands for Laser-Induced Breakdown Spectroscopy. Put simply, it is a method of identifying the constituent elements by firing a strong laser pulse at a sample to instantly turn it into a plasma state, and then analysing the spectrum of light emitted as the plasma cools. The...

In this blog post, we’ll focus on temperature and thermal management systems—particularly the role of thermal interface material (TIM)—which significantly impact the lifespan of LEDs.   LEDs and Heat: Why Temperature Matters An LED (Light Emitting Diode) is a device that emits light when an electric current flows through a compound semiconductor junction, causing electrons and holes to...

In this blog post, I will provide an easy-to-understand overview of the basic principles and structures of LCD and OLED, as well as the pros and cons of each technology.   Basic Concepts of Displays Displays are core components that serve as the “face” of most electronic devices, such as TVs, computers, and smartphones. As electronic devices have become more sophisticated, the demand for...

In this blog post, I will summarize the current state of K League broadcasts and related programs, as well as the reasons why they need to be improved.   Current Situation: Broadcasts Focus on European Soccer, K League Takes a Back Seat Currently, soccer-related programming in Korea is overly biased toward European leagues, while K League-related broadcasts are relatively scarce.
