In this blog post, we’ll explore various technologies for controlling car noise, as well as the principles and future directions of the latest technologies designed to transform unpleasant sounds into pleasant ones.   “Vroom, vroom.” When walking along the roadside, it’s natural to frown at the noise emitted by countless cars. In fact, on roads with heavy traffic, it’s often difficult to...

In this blog post, I’ll examine from a philosophical perspective whether humans would truly be happier if advances in science and technology made eternal life possible.   Most people have likely experienced a time when they felt sick or unwell and visited a hospital, worried that they might have a serious illness. Humans are, by nature, beings driven by the desire to survive. Based on this...

In this blog post, we’ll explore what artificial photosynthesis is, what its advantages are, how far research has progressed, and what challenges remain on the path to practical application.   Introduction: Resource Challenges and Solar Energy While humanity’s demand for energy and resources continues to grow, the Earth’s resources are finite. In particular, non-renewable resources such as...

Banks use deposited money to make loans, and in reality, not all of that money stays in the bank. Discover the hidden principles of the banking system, which originated with goldsmiths!   The Money Lended Out Isn’t Actually in the Bank The “reserve requirement” means that banks are allowed to lend out all but 10% of total deposits. However, for this to be possible, another前提 is necessary:...

In this blog post, we’ll explore the innovations and real-world applications of silver nanotechnology, its potential risks, and whether this future technology will be a blessing or a new challenge for us.   These days, the term “nano” is commonly encountered across a wide range of fields. From smartphones to cosmetics, medical devices, pharmaceuticals, and semiconductors, nanotechnology is...

In this blog post, we’ll examine, from the perspective of modern evolutionary biology, the role genes play in shaping phenotype and how their influence is understood in the context of interactions with the environment.   We use the biological term “gene” very frequently in everyday conversation. For example, there are countless expressions referring to genes, such as “genes for height,”...

In this blog post, we’ll explore what the advancement of gene-editing technology means for individuals’ lives and free will, and examine the issues surrounding “natural humans” and “designer humans” through the lens of the films ‘Gattaca’ and ‘The Truman Show’.   Advances in Genetic Engineering and the Questions Raised by “Gattaca” Genetic engineering and human...

In this blog post, we’ll explore the history of genetic engineering and GMOs, their advantages and limitations, safety controversies, and the extent to which we can control their impact.   Warnings About Genetic Engineering The film ‘Planet of the Apes’ has been remade several times; based on a novel, it was first adapted into a movie in 1968, and sequels and reboots have been...

In this blog post, we’ll examine how the conventional wisdom and knowledge that humans have held have changed through the evolution of science from classical physics to quantum mechanics.   “I think, therefore I am.” This is the first proposition presented by Descartes to establish an unshakable foundation of knowledge, in opposition to the skeptics of his time who argued that, because...

In this blog post, we examine whether reductionism helps us understand complex phenomena or whether it distorts the whole.   Reductionism is the view that, when interpreting complex phenomena, breaking them down into their most basic units and analyzing each one will ultimately lead to an understanding of the phenomenon as a whole. This perspective has been applied not only in science but...
