In this blog post, we’ll explain in simple terms the limitations of computer-generated random numbers, the nature of randomness, and the difference between TRNGs and PRNGs. “If there’s one thing computers are really bad at, it’s flipping a coin.” These are the words of Steve Ward, a professor in the Department of Computer Science at MIT. He means that because today’s computers can only...
In this blog post, we’ll explore why medieval and Renaissance physicians didn’t question Galen’s physiology. We’ll examine why his theories maintained their authority for so long. From the Middle Ages through the Renaissance, the undisputed authority in the field of physiology was Claudius Galenus, who systematized Greek medicine around the 2nd century. According to Claudius Galenus...
In this blog post, we’ll take a step-by-step look at the principles and main methods of 3D printing technology, as well as its material limitations and future applications. Why Is 3D Printing Gaining Attention? Imagine a situation where a sudden illness or accident creates an urgent need for a custom-made replacement part. For example, if a father collapses from a heart attack, finding a...
In this blog post, we’ll take a step-by-step look at the principles and main methods of 3D printing, its applications and challenges, and its future potential. The Evolution of Printing and the Emergence of 3D Printers Amid the ceaseless flood of printed materials, it’s hard to imagine daily life without printing technology. Just as Gutenberg’s movable-type printing in the Middle Ages...
In this blog post, we’ll take a look at the current state of 3D printing technology, examples of its applications, ethical issues, and the future outlook (diversification of materials and expansion of production scale), in that order. How 3D Printers Will Change Our Lives and the Market Let’s think about a tangible “3D” object. In the past, if you wanted to buy a small coffee maker, you...
In this blog post, we’ll explore how 0s and 1s are repeated and utilized inside electronic devices through the “Dodge the Poop” game. Modern Society and the Foundations of Digital Technology Modern society is one where cutting-edge equipment is ubiquitous—in homes, offices, cars, and on the streets. We now have self-parking cars, and we can even operate our home’s boiler while we’re out...
In this blog post, we’ll examine the anticipated challenges and countermeasures at each stage by dividing the development of artificial intelligence into early, mid, and late phases. The prediction that “by 2045, AI will surpass humanity…” is a claim Ray Kurzweil has made on numerous occasions. In his book ‘The Singularity Is Near’ and elsewhere, he argues that the...
In this blog post, I’ll explore how documentaries and feature films are intertwined and influence one another. The Meaning and Dramatic Nature of Documentaries The term “documentary” translates to “record” in Korean. In other words, a documentary refers to a specific part of reality captured on camera. That part can be seen as a condensed version or summary of the world the director wishes...
In this blog post, I will provide an easy-to-understand overview of the principles, characteristics, general rules, and practical applications of the Diels-Alder reaction. The Diels-Alder Reaction in Organic Chemistry and Total Synthesis Organic chemistry is the field that deals with carbon compounds and plays a central role in various areas, including chemical processes, biological...
In this blog post, we’ll explain three key techniques for boosting CPU performance—pipelining, memory hierarchy, and multithreading—in a simple and accessible way. Overview Speed is a key factor when evaluating a computer’s performance, and one of the primary ways to increase that speed is by improving CPU performance. The CPU plays a role similar to the human brain in a computer system...
