The Internet of Things (IoT) is a technology that connects various objects via networks to share information and establish automated systems, significantly enhancing convenience and efficiency in homes and industries.   You’ve probably seen descriptions in school textbooks from your childhood about how a light left on by someone rushing out of class could detect the absence of people...

This blog post explores how the uncertainty principle of quantum mechanics and the concept of wu-wei (non-action) in Eastern philosophy bridge science and philosophy. It offers new insights through the connection points between these two fields.   Quantum mechanics is both the culmination of highly developed modern physics and a new starting point. The discovery of quantum mechanics was a...

In this blog post, we explore the reasons why the Copenhagen interpretation has garnered significant support over time among the various interpretations of quantum mechanics, despite its complexity.   Quantum mechanics is the science applied to microscopic particles like atoms and molecules. It forms the foundation of semiconductors, including transistors, and has profoundly influenced...

This blog post examines the claim that the mind creates reality from a quantum physics perspective.   Introduction Do you remember ‘The Secret’, a book that was a long-term bestseller at Kyobo Book Centre in Korea during 2007 and 2008? It was a book about a ‘secret’ that supposedly allowed you to obtain everything, whether it was money or beauty. That secret was the ‘Law of Attraction’. It...

In this blog post, we examine why Einstein never fully accepted quantum mechanics and ponder whether his stance was stubbornness or perseverance.   Among the scientists who lived in the same era as Werner Heisenberg, there is one figure we know well: Albert Einstein. He is the famous scientist who opened a new chapter in physics by proposing the theory of relativity. However, when quantum...

This blog post explores how quantum mechanics transcended the laws of causality in classical mechanics and the resulting shift in worldview.   Classical mechanics served as the fundamental theory by which physicists described the world until the early 20th century. It included two key assumptions. The first assumption is that measuring one physical property of an object can be done without...

In this blog post, we explore how stable isotopes, through microscopic observation, have become a tool for illuminating the macro world—revealing ancient environments, human migration, and climate change.   Humans have long pursued science to understand smaller things. This human curiosity has driven us to constantly break down and analyze the world, seeking deeper understanding. For...

This blog post examines why safe drinking water remains inaccessible for many and explores the potential and limitations of appropriate technology to address this issue.   What happens if you drink contaminated water? Countless people worldwide still drink contaminated water. According to the World Health Organization (WHO), approximately 29% of the global population still lacks access to...

This blog post takes an in-depth look at whether euthanasia is a right to a dignified death or a choice that could lead to a disregard for life and ethical confusion.   Euthanasia refers to the act of artificially hastening death to alleviate the suffering of patients afflicted with incurable diseases or similar conditions. As a sensitive issue concerning human life, it has been the subject...

This blog post explores the impact recurring nightmares have on our routines and introduces practical methods to regulate and overcome them.   Humans spend one-third of their lives asleep. During this time, which can feel both long and short, we experience countless dreams. Sleep plays a vital role in our lives, allowing our bodies and minds to recover and recharge. Yet, sometimes this...
