In the context of the third industrial revolution, electric vehicles have gained prominence as an environmentally friendly alternative, but they are not a fundamental solution to the energy problem, and the charging infrastructure and consumer value have not been met. In contrast, hydrogen internal combustion engine vehicles are being seen as a potential solution to both environmental and...

  This article uses the flow of cigarette smoke to illustrate the basic principles and applications of fluid dynamics. It covers fluid motion and various hydrodynamic phenomena, such as laminar flow, turbulence, and detachment, using everyday examples to emphasize their importance and applications.   Fluid Dynamics Through Cigarette Smoke We all have memories of watching our...

In chemical engineering, separation processes are essential for obtaining the desired product and are responsible for efficiently separating the different substances produced after a reaction. Various techniques, such as distillation and membrane separation, can be utilized to increase purity and reduce costs, and they play an important role in many industries beyond chemical processing.  ...

As artificial intelligence robots develop, situations where they demand freedom may become a reality. This article explores the meaning of freedom and raises the ethical and philosophical question of whether robots can be recognized as autonomous beings rather than mere possessions.   In 2005, the Richard family makes a surprising purchase. It’s Andrew the Robot (NDR-114). This...

  This article explains the transition from modern architecture to postmodern architecture through a change in humanity’s view of truth. Based on a critique of the efficiency and rationality of modern architecture, it emphasizes that postmodern architecture is an attempt to restore human aesthetic sense in an inefficient and asymmetrical form.   What is truth? It may seem like an...

  Computer science is a rapidly evolving discipline, with new paradigms constantly emerging that emphasize the balance between performance and correctness. Analyze the unique way computer science has developed compared to theories of scientific revolutions and explore the impact of the latest technologies, such as artificial intelligence and quantum computing, on its progress.  ...

  Underground spaces are gaining attention as an alternative solution to population growth and resource scarcity. Utilized since ancient times, underground spaces have expanded with technological advances to include a variety of uses, including housing, industry, and energy, and are playing an important role in future projects such as nuclear waste storage and high-speed transportation...

  Microfluidic devices are an innovative technology that overcomes the limitations of traditional two-dimensional experiments by culturing cells in a three-dimensional environment to mimic in vivo conditions. This technology provides more accurate results in anticancer drug efficacy testing and diagnostics, and has the potential to transform cancer research and treatment.   Microfluidic...

  Graphene is a thin, two-dimensional structure made of carbon atoms that is 200 times stronger than steel, electrically conductive, flexible and transparent. It can be used in a variety of fields, including semiconductors, batteries, medicine, and electronics, but it is expected to be commercialised only after overcoming the limitations of mass production.   Graphene, the new material...
