Hydrogen fuel cells are a renewable energy source that can solve the problems of fossil fuel depletion and environmental pollution. It generates energy by reversing the decomposition of water, and it is noiseless and does not have to worry about resource depletion. It is also highly anticipated as a future energy source due to its high efficiency and various application possibilities.  ...

Cryonics is being studied as a way to treat terminal illnesses and extend life, and it is also expected to play a role in future industries such as space development. However, despite the success of the cooling phase, there are still many challenges to overcome, such as brain damage during the thawing process. Scientists are still hoping to overcome this with future technologies.   People...

This article covers the changes and evolution of programming paradigms, explaining the characteristics and advantages of procedural, object-oriented, and functional programming. The main paradigms used in modern software development are complementary to each other, and there are expectations for new paradigms to emerge in the future.   Although object-oriented programming is the most widely...

Jimi Hendrix’s introduction of the overdriven sound and innovative playing techniques revolutionized the electric guitar. His daring stage performances and unique musical style had a profound impact on subsequent guitarists, and despite his later death, he is still revered as the ‘guitar god’.   Around the 12th century, the guitar first appeared on the scene. The electric...

In this article, we’ll discuss how, while it may seem like the only way to succeed is to stay ahead of the game, sometimes it’s more empowering to pause and find your true passion. It emphasizes the importance of enjoying life and looking at it as a time to recharge, rather than a time to lose.   We live in an era of endless competition. In order to do what we love and want to...

The popularization of Wi-Fi in the information age has provided many conveniences, but there are concerns that excessive installation and use can have adverse health effects. Some argue that it should be regulated in certain places, such as daycare centers and hospitals, and this requires careful consideration.   Unlike material, information is difficult to monopolize. As a result, it was...

If robots with human-like intelligence and morality are developed, we need to discuss whether we can entrust them with important decisions that humans make. We conclude that it is difficult to entrust robots with all decisions due to their lack of accountability, value judgment, and creativity.   However, if robots are created with intelligence and morals close to those of humans, will we be...

This article explains the principles and role of semiconductors in enabling the development of information and communication technologies, and covers the impact and importance of the semiconductor industry on modern society and economies. It discusses how the development and evolution of semiconductors has put them at the center of the digital revolution and what role they will play in future...

By explaining the structure and principles of a thermos, specifically how heat is transferred by conduction, convection, and radiation, this course explains the science behind why a thermos keeps drinks hot longer, and in doing so, explores the scientific principles behind everyday objects.   A thermos bottle keeps cold drinks cold and warm drinks warm. These ubiquitous objects first...

There are arguments that governments should regulate the minimum cooling temperature of air conditioners, given that low air conditioner settings lead to excessive energy waste and health problems such as cooling sickness. Limiting the minimum temperature can be a practical way to protect people’s health and reduce electricity consumption.   In summer, the sun is shining outside the...
