Optical camouflage was once the stuff of science fiction, but modern technological advances are making it a reality. This technology can raise ethical issues, especially because of its potential military applications, and we need to think about its responsible use in the context of the value-neutrality debate in science and technology.   Introduction Optical camouflage has long been a...

  Advances in space exploration and rocket science are making space travel a reality that humans could only imagine in the past. While private space travel is becoming increasingly commercialised, Korea is also working hard to develop its own rocket. The time when space is no longer a dream, but a reality, is just around the corner.   Outer space, beyond the horizon! The human...

  A bladeless fan uses the Coanda effect and Bernoulli’s principle of fluid dynamics to generate wind without wings. Safe and efficient thanks to its mechanical design, this innovative product is the result of the application of the principles of fluid dynamics in various fields.   Mechanical engineering and a fan without blades The first appliance that comes to mind during the...

This article discusses the different ways in which science and religion pursue truth and the resulting conflicts. It examines the relationship between science and religion through three main perspectives and discusses whether religion still has value in the modern world.   Science and religion. These are two topics that seem to go hand in hand, yet they are constantly discussed together...

  This article highlights that advances in engineering technology cannot be successfully commercialised and performed in the marketplace without the integration of business administration. It explains the importance of managerial thinking for engineering students, and suggests that business administration will play a key role in the future engineering revolution.   The need for...

Macromolecules are widely used in everyday life and have been with mankind since ancient times. This article covers what they are, their historical development, and explores their potential applications in future nanotechnology and medicine, particularly through the properties of block copolymers.   In this blog post, I’d like to talk about macromolecules, an area of research that is...

  Dye-sensitised solar cells are a next-generation technology for generating electricity from sunlight that is flexible, adaptable to a variety of surfaces, affordable and environmentally friendly. This technology has the potential to revolutionise clothing, building materials and more.   Current energy challenges and alternatives Currently, we rely on fossil fuels and nuclear power for...

  Quantum computers are based on qubits, which perform far more complex and powerful operations than bits, and can efficiently solve problems such as prime factorisation. However, their sensitivity to the external environment and lack of practical algorithms have hindered their commercialisation.   About quantum computers A few years ago, the world’s first commercially available...

The Boeing 747 has played a historic role in the aviation industry for many years, but newer aircraft like the A380 and B787 are now taking over. The A380 uses the benefits of a large aircraft to carry a large number of passengers, while the B787 emphasises fast flight and fuel efficiency. Both aircraft are leading the fleet generation shift with different strategies.   Currently, the most...

  A technology that allows you to watch 3D movies with your bare eyes without stereoscopic glasses is becoming a reality through the research of Professor Kookheon Cha of Seoul National University. This technology, based on research on polymer thin films in chemical biomedical engineering, has the potential to be applied to various industries and is expected to be used in future daily life...
