In this blog post, we’ll explore the concepts of scientific design and optimal design as applied in mechanical engineering, as well as the role that optimal design plays in product design.   What Are Scientific Design and Optimal Design? In the past, the importance of product design garnered significant attention due to patent disputes surrounding smartphones. In the lawsuits between Samsung...

In this blog post, we’ll explore the concept, characteristics, limitations, and future direction of evidence-based medicine—an approach that evaluates medical decisions based on scientific evidence.   What Is Evidence-Based Medicine? A patient visited the hospital, distressed by a persistent cough and sleepless nights caused by it. After asking a few questions and conducting a physical...

In this blog post, we’ll examine the principles behind stealth technology applied to modern warships and the various ways it’s implemented, and explore what this technology means for naval power.   The Power of Stealth Demonstrated by Submarines   “We have lost more men than Admiral Nelson lost in all the battles he fought throughout his entire life.” This remark is said to have been...

In this blog post, we’ll explore why transit card readers are equipped with clocks by examining the principles behind electronic clocks and quartz oscillators.   Electronic Clocks and Quartz Oscillators Just a few decades ago, clocks were considered luxury items, but those days are long gone. Every room has at least one wall clock, and clocks are built into computers, smartphones, and...

In this blog post, we’ll examine the advancements in vehicle dynamics control technology and explore how advanced driver-assistance systems are helping to reduce traffic accidents.   The history of the automobile truly began with the development of the internal combustion engine. In 1860, Étienne Renoir of France developed a functional internal combustion engine, and in 1876, Nikolaus Otto...

In this blog post, we’ll examine the principles and processes by which traffic engineering uses real-time traffic information to reduce travel time during the holiday season.   During Seollal and Chuseok—the nation’s two major holidays—private vehicles heading to their hometowns congest the highways, leading to recurring traffic jams. Such traffic congestion causes significant losses not...

In this blog post, we will examine why the petition by the Committee for the Revision of Evolution Theory in Textbooks to remove evolution theory became controversial and what specific criticisms it faced.   The Petition by the Committee for the Revision of Evolution Theory in Textbooks and the Social Controversy In June 2012, the world-renowned scientific journal ‘Nature’...

In this blog post, I’ll examine the historical events and thoughts on modern politics that the movie ‘Gwanghae: The Man Who Became King’ brought to mind, while correcting and editing them to align with current facts.   The movie ‘Gwanghae: The Man Who Became King’ was a huge box office hit, drawing over 10 million viewers. I had wanted to see it, but I lacked the...

In this blog post, we’ll explore the concept and importance of optical isomers, as well as their significance in pharmaceuticals and biological processes.   The world we live in is made up of various small particles. Among them, the most functional and readily accessible particles are molecules. Molecules are composed of various types of atoms, and each molecule has its own unique molecular...

In this blog post, we’ll explore the principles behind optical fibers—which have made today’s ultra-high-speed optical communications possible—and “thermal migration,” the key technology used to manufacture them.   Today, we use the internet every single day without fail. The internet allows us to easily exchange information from all corners of the world, no matter where we are on the globe...
