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...

Chemical engineering has a profound impact on our daily lives and industries, including synthetic fibers and plastics, electronic device materials, and energy resource processing. It is linked to various fields and plays an important role in solving environmental pollution problems and developing green energy, and is systematically taught in undergraduate schools from basic subjects to advanced...

This article discusses whether animal testing is an essential part of the process of treating human diseases and ensuring human safety, or an unnecessary practice that violates animal rights. While animal testing has successfully led to the discovery of new medicines, due to the physiological differences between humans and animals, safety cannot always be guaranteed, and testing for non-essential...

This article explores the positive impact that AI robots will have on our daily lives, as well as the fears of a sci-fi future of robotic oppression of humans. Using examples from movies, we’ll compare the ethical and technological limitations of AI robots with the concept of human free will, and suggest possibilities and positive uses in the real world.   What do you think of when you...

In science fiction movies, robots are portrayed as thinking and conversing naturally with humans, but in reality, AI reacts based on pre-stored data and doesn’t have the ability to truly think. The quest for strong artificial intelligence has been ongoing since the Turing Test and the Chinese Room experiment, but the emergence of AI that can understand new concepts and think creatively like...

Evolutionary theory is a theory that explains how organisms change over time, and it uses mechanisms such as natural selection and gene drift to illustrate the process. Modern evolutionary theory has had a profound impact on many fields beyond biology, including the humanities and social sciences, and its importance has been expanded by attempts to explain the evolution of culture and language...

Why is analog circuit design still essential in an era dominated by digital technology? The ability to process continuous analog signals, such as voice, touch, and environmental data, and digitize them enables us to communicate with the real world. In particular, autonomous driving, smartphones, and medical devices require precise data processing that combines digital and analog signals.  ...

Electrical engineering is not just about electricity, but is a comprehensive and applied discipline that is closely connected to various fields such as electric energy, communication, control, semiconductor, electrophysics, computer, and biomedical. Electrical technology is essential in modern society and can be applied to many industries, and graduates of the Department of Electrical Engineering...

Just as giraffes evolved longer necks to give them an advantage in survival, so too did evolution and natural selection give rise to Homo sapiens. However, we are now using science to create ourselves, and to cross the boundary between biology and humanity through intelligent design, including genetic manipulation, cyborg engineering, and non-organic engineering. This suggests the possibility of...
