In this blog post, based on the history of how humans have overcome their biological limitations and the advancements in cyborg engineering, we will examine the meaning of the “end” that Homo sapiens will face as they transform into a new form of existence: the cyborg. It has been approximately 300,000 years since Homo sapiens, modern humans, first appeared. While the entire history of...
What is the Internet of Things (IoT), and how are the objects in our lives connected?
In this blog post, we’ll explore the concept and operating principles of the Internet of Things (IoT), the sensors and communication technologies that enable it, real-world use cases, and the security issues that are becoming increasingly important as the IoT continues to spread. These days, it’s not uncommon to hear the term “Internet of Things” in everyday conversation. The Internet...
How are the human eye and machines similar, and how do machines and computer vision perceive the world?
In this blog post, we’ll explore the principles behind how the human eye recognizes objects and how computer vision mimics this process to recognize and process the movements of objects and people. Nintendo’s “Wii” game console, which sold over 70 million units worldwide and held a significant market share in the gaming console market, was a huge hit because it allowed users to...
The Light Revolution: Can SPP-Based Optical Integrated Circuits Surpass Semiconductors?
In this blog post, we’ll examine the limitations of electronics—a field long dominated by semiconductors—and explore how optical integrated circuits, which utilize light, and their core technology, SPP, can overcome these limitations. Technology has evolved as the times have changed. In the Stone Age, people used stone, and as time went on, they began crafting daily necessities and weapons...
The Big Bang Theory and Karl Popper’s Theory of Falsifiability: Where Did We Come From, Who Are We, and Where Are We Going?
In this blog post, we examine the fundamental questions posed by Paul Gauguin’s painting ‘Where Do We Come From? What Are We? Where Are We Going?’ from the perspectives of the Big Bang theory, the cosmic microwave background, the theory of inflation, and Karl Popper’s concept of falsifiability. Where Did We Come From? The painting ‘Where Do We Come From? Who Are We? Where...
Hadoop, the “magician” of big data processing—how does it store and analyze such vast amounts of data?
In this blog post, we’ll explore the core principles of Hadoop—which distributes the storage and processing of big data across multiple computers—as well as HDFS, MapReduce, cluster architecture, and the evolution of the Hadoop ecosystem to this day. Social media and online services are generating enormous amounts of data even as we speak. Users constantly share where they’ve been, what...
How do airplanes fly through the sky, and how do they unlock the mysteries of modern civilization?
In this blog post, we’ll examine the principles that allow airplanes to fly from an aerodynamic perspective and explore how aeronautical engineering is connected to our lives. Have you ever planned a backpacking trip that made your heart race just thinking about it? On the day of departure, standing at the airport and looking at that massive machine, have you ever wondered, “How can I fly...
How can an airplane use the force of air to lift its heavy body into the sky?
In this blog post, we’ll explore the basic principles of fluid dynamics—the study of air and water—and examine how the airflow and pressure differences around an airplane’s wings generate lift, enabling the heavy aircraft to take flight. If we were to list the substances essential for life on Earth, what would they be? Many people would think of air and water. Air and water play an...
How do emergency evacuation slides—which save lives in plane crashes—work?
In this blog post, we’ll examine the structure and operating principles of emergency evacuation slides, which help passengers evacuate quickly in critical situations such as plane crashes, as well as the technology that rapidly inflates these massive slides using a small amount of compressed gas. Even if a car or ship breaks down while in operation, it can, depending on the situation...
How does BitTorrent share files, and why should you use it with caution?
In this blog post, we’ll examine the basic operating principles of BitTorrent, how it differs from traditional client-server and P2P models, the roles of torrent files, peers, and seeders, and the precautions you should take when using copyrighted material. When we want information, we search the internet, and when we need files, we download them for use. There are many ways to obtain...
