With the development of biotechnology, we need to think about whether we will remain Homo sapiens or whether a new species will emerge and change the direction of our evolution. Biotechnology can bring great benefits to humanity, but we must also carefully consider the ethical issues and side effects of the technology.   Humanity has gradually evolved into more advanced forms, starting with...

Pesticides are essential for increasing food productivity, but in the long run, they cause serious damage to the environment, ecosystems, and human health. Alternatives to minimize pesticide use, such as eco-friendly farming, improved varieties, and glasshouse technology, have been proposed, increasing the importance of sustainable agriculture.   Food is the most important resource for human...

Inspired by the technology in the movie Iron Man, this article imagines a future where the lines between humans and machines are blurred, and considers how we define the difference between human identity and robotics. We discuss the possibilities of advances in science and technology and the resulting changes in human identity, and ask whether we will still be Homo sapiens in the future.  ...

This article explains how smartphones have become an essential tool in our daily lives, and discusses how they have evolved into miniaturized computers through advances in semiconductor technology, integrated circuits, Moore’s Law, and more, and what the future holds.   In 2024, our day begins with a smartphone, where we search for news or check social media messages. During the...

In the modern world, where the meaning given to humans by God has disappeared, social ideologies such as liberalism and human rights have provided new normative values for individuals. However, individuals still have the freedom to choose not to conform to society’s values, which shows the impact of the rise of humanism on human values. Society uses normative values to give meaning to...

The food and nutrition and foodservice industries play a vital role in improving quality of life and shaping a greener, more sustainable food culture that goes beyond just providing meals. It’s a move towards socially responsible eating, where health and the environment are considered at the same time.   What is one activity that you typically do that you can’t go a single day...

This article describes the similarities between the central role of a principal in school operations and the critical role of a controller in a mechanical system. It specifically addresses how school operations are connected to how mechanical systems are controlled, emphasizing their importance and effectiveness.   What are the differences between schools with and without a principal...

The exploration of human origins begins with understanding the process of natural selection at different levels through the theory of evolution. Along the way, Darwin’s theory has been expanded by scholars like Dawkins to show that evolution can occur at multiple levels, including genes, individuals, and populations. These discussions play an important role in helping humans understand...

Electrical engineering provides the core technology for robotics, and the four disciplines of electricity, electronics, control, and computers play an essential role in advancing the design, control, and cognitive capabilities of robots.   What is electrical engineering and why do I need it to study robotics? As mentioned earlier, the core technology for robotics comes from electrical...

Using the cuckoo’s reproductive strategy and the prisoner’s dilemma, we explore the recurrent reciprocity hypothesis, which explains why selfish organisms choose altruistic behavior in repeated interactions. The hypothesis uses the examples of mating and vampire bats to shed light on the complexity of altruistic behavior in human and animal societies, and discusses how these behaviors...
