In this blog post, we’ll explore what engineering beauty is by examining the engineering principles and structural characteristics of truss bridges.   What is engineering beauty? When we think of beauty, we often imagine the aesthetic value found in landscapes such as natural scenery, parks, or beautiful buildings. However, beauty exists in far more diverse places around us. Have you ever...

In this blog post, we’ll take an in-depth look at the structure and properties of carbon fiber, the principles behind carbon fiber-reinforced plastic (CFRP), its applications across various industries, and its future prospects.   The Rise of Carbon Fiber-Reinforced Plastic In the automotive industry, a new material is rapidly gaining traction as a replacement for steel, which has long been...

In this blog post, we’ll explore the structure of the tower crane—often called the “flower of the construction site”—and examine the principles behind its installation and dismantling processes.   The Tower Crane: The “Flower of the Construction Site” The tower crane is one of the key pieces of equipment on a construction site and is the first thing that catches your eye at high-rise...

In this blog post, we’ll take an easy-to-understand look at everything from why couple rings are worn on the ring finger to the differences between 24K, 18K, and 14K gold, the necessity of gold alloys, the principles behind the colors of white gold and rose gold, and the differences between white gold and platinum.   Why Are Couple Rings Worn on the Ring Finger? Stories linking fingers to...

In this blog post, we’ll explore why green ships are gaining attention, changes in international environmental regulations, and the direction of the latest green ship technologies, including LNG, methanol, and ammonia-powered vessels.   Tightening Environmental Regulations and the Emergence of Green Ships As climate change and carbon neutrality have recently emerged as global challenges, the...

In this blog post, we’ll take a simple and fun look at the principles behind the Sn2 reaction—one of chemistry’s most representative substitution reactions—by comparing it to a romantic relationship.   How Does Chemistry Explain Human Relationships? Chemistry is the study of the countless elements that make up our world. Perhaps this is because humans are also part of that world. Many...

In this blog post, we’ll examine the principles behind a soccer ball’s curve, focusing on fluid dynamics and the Magnus force, and explore the science behind the “banana kick.”   “A soccer ball is round.” This is a phrase often heard when a team considered the underdog in a match pulls off an unexpected victory, or when a dramatic comeback occurs in a situation that seemed all but lost. The...

In this blog post, we’ll explore the principles behind reinforced concrete, its advantages and disadvantages, and why it’s the most widely used material in buildings today.   Definition and Characteristics of Concrete Structural materials are just as important in buildings as the technology used in their construction. Concrete is one of the most widely used structural materials today, and we...

In this blog post, we’ll take a simple look at why chords sound beautiful—focusing on vibrational modes—and explore the physical principles behind this phenomenon and how they’re applied to instrument making.   Memories from School Days and a Sense of Curiosity Do you remember finding music theory classes boring back in school?
