In this blog post, we’ll examine why shots commonly referred to in soccer as “spinless shots” or “knuckleballs” wobble erratically through the air, from the perspective of fluid dynamics and airflow. Today, the so-called “spin-free shot”—a shot with almost no spin—is attracting significant attention from many soccer players and fans. On online video sites, it’s easy to find not only...
How does Mercedes-Benz’s body stability technology reduce body roll and create a comfortable ride?
In this blog post, we’ll explore the evolution of body stability technology—from the basic principles of suspension, which determine a car’s ride comfort, to Mercedes-Benz’s Active Body Control (ABC), Magic Body Control, and today’s E-ACTIVE BODY CONTROL. As cars have become deeply integrated into everyday life, people now spend more time inside them than ever before. Consequently, the...
How did machine learning become a core technology of artificial intelligence?
In this blog post, we’ll explore the concept of artificial intelligence, the principles of machine learning, the difference between supervised and unsupervised learning, the pros and cons of machine learning, and its various applications. Artificial intelligence (AI) became a global topic of discussion following the match between AlphaGo—an AI developed by Google—and Lee Sedol, the world’s...
What are the ethical issues surrounding designer babies?
In this blog post, I’d like to examine the ethical issues surrounding designer babies—ranging from the birth of designer babies for therapeutic purposes to embryo selection and disposal, the human rights and freedom of choice of designer babies, the potential for misuse of the technology, and social inequality. There is a movie called ‘My Sister’s Keeper’ that tells the story...
How Can Micro- and Nano-Robots Transform Disease Treatment and Surgery?
In this blog post, we will explore the concept of micro- and nano-robots, their potential applications in the medical field, the advantages they offer in improving existing treatments, and the limitations and side effects of this technology. While medical technology has been advancing by leaps and bounds recently, there is a growing need for methods to address new diseases and treat...
How have the twelve episodes of Lineage shaped the history of the World of Aden?
In this blog post, we’ll explore how the early episodes of Lineage—beginning with the Talking Island and continuing through Gludio, Kent Castle, the Fairy Forest, the Valley of the Dragons, Giran, Heine, the Fire Dragon’s Nest, and Oren, all the way to Aden—have shaped the world and its stories. Episode 1: “The Talking Island” First introduced in September 1998, the Talking Island served...
What kind of future will mechanical and aerospace engineering—the driving force behind rocket and aerospace technology—create?
In this blog post, we’ll explore everything from the principles of rocket propulsion to aerospace control research, and examine how mechanical and aerospace engineering plays a role in realizing humanity’s dreams of reaching space. “4, 3, 2, 1… Launch!” Just hearing this countdown and the word “launch” brings to mind a rocket blasting off into space. At that very moment, neither the...
How has robotics evolved as a field of science and technology through the convergence of various disciplines?
In this blog post, we’ll explore the characteristics of robotics—which has evolved through the convergence of knowledge from various disciplines, including mechanical engineering—as well as the structure of robotic arms, their control principles, and their role in industrial settings. When many people hear the term “mechanical engineering,” they likely think of cars, gears, or factories...
Why do lasers produce such intense light?
In this blog post, we’ll explore the principles behind why lasers produce light that is far more intense than ordinary light sources, using the concepts of stimulated emission, optical pumping, population inversion, and the directionality of light. “Fire the laser beam!” This is a line often heard in robot animated movies. The green laser beams fired from robotic arms are usually powerful...
How can we analyze complex structures, such as LEGO sets, and predict their safety?
In this blog post, we’ll explore the principles, applications, and limitations of finite element analysis—a method that breaks down complex structures, like LEGO sets, into small elements for analysis. Among the countless toys loved by children, LEGO is a must-mention. LEGO is a toy consisting of colorful blocks of various sizes that are interlocked to build large objects; its appeal lies...
