E-paper’s bistability, reflective properties, and flexibility make it low-power and eco-friendly, and it’s finding applications in e-books, smartwatches, electronic price tags, and more. By combining the advantages of traditional paper with display technology, e-paper is increasingly becoming a new alternative to protect the environment and reduce costs, and it has the potential to...

This article explains the concept of a “singularity” – the point at which technology transcends humans – and relates it to a change in the state of matter. The interaction of temperature and pressure transforms matter into solids, liquids, and gases, and when a critical point is crossed, a “supercritical fluid” is formed that has properties of both liquids and gases. Supercritical...

Advances in genetic engineering have made it possible to manipulate the appearance and abilities of our children, not only to cure diseases, but also to create ethical problems and social inequalities.   Genetic engineering has come a long way, and as a result, people have mixed reactions to it: hopeful and worried. While some people are hopeful that modern medical technology will be able to...

Display technology has evolved from black-and-white TVs, through LCDs and PDPs, to innovative technologies like OLEDs, especially transparent OLEDs. Transparent displays are nearing commercialization, with the promise of new functions and roles in smart homes, autonomous driving, healthcare, education, and more.   From the first black-and-white TVs in the 1960s, to PDPs, LCDs, and now 3D...

  In 2018, gene editing became a reality with the successful gene-editing experiment on human embryos in China, thanks to CRISPR/Cas9. While this technology holds the promise of curing genetic diseases and improving the quality of human life, it also raises the risk of misuse and ethical controversy. Gene editing can lead to social inequality, especially in the form of designer babies, and...

This article questions whether science can determine absolute truths about the natural world, examining the history of science and the positions of various philosophers of science. It discusses the possibility that scientific knowledge is always subject to change, just as the theories of Newton and Einstein have been revised over time. It concludes that science explores the external world, but is...

The gaming market has exploded with technological advancements, but it takes more than just graphics and technology to succeed. The past failures of Atari and the success of Nintendo show that inherent fun and differentiated content are key to ensuring a game’s long-term success.   Since the first simple tennis video game called Pong, games have become increasingly flashy and...

As biotechnology advances, animal testing is increasing for human health and convenience, but the sacrifice of millions of animals raises questions about whether it is justified. We need to rethink whether it’s right to inflict pain on animals just because we are superior, protect animal rights, and shift to life-centered thinking.   Recent advances in biotechnology have led to the...

This article explains how semiconductors are so deeply involved in our daily lives, and introduces you to their principles, functions, and various applications. Semiconductors are able to control the flow of electric current by the direction of the voltage, which allows them to power and control electronic devices. Semiconductors are applied to various devices, from computer CPUs to LEDs, digital...

In movies, the killer’s voice over the phone sounds bizarre and alien, which adds to the suspense. This is due to the frequency band limitations of phones and the effect of voice modulation. As the voice is converted into electrical signals, the original timbre and sound quality is altered, and horror movies in particular maximize this feature to immerse the audience. Recently, AI...
