I’m Ken Kuwako, your science trainer. Every day is an experiment! Have you ever seen a book hanging more than halfway off the edge of a desk without falling? It looks like a magic trick, but there is a perfectly logical scientific secret behind it. Today, let’s use the laws of physics to explore how […]

I’m Ken Kuwako, Science Trainer. Every day is an experiment. Return to Special Page When you think of “generating electricity,” do you imagine massive dams or giant power plants? In reality, the same mechanism used in the heart of a power plant is hidden inside tiny toys that fit in the palm of your hand. […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. 【This article is also available on Radio!】 If I told you there’s a “mysterious water” that changes color just by shaking it, would you believe me? Imagine a potion brewed by a wizard—shifting from yellow to red, then to green, and eventually fading back […]

I am Ken Kuwako, your science trainer. Every day is an experiment! Our world is absolutely flooded with waves—sound, light, earthquakes, and even the signals for your smartphone. However, it is a well-known fact that many students find physics suddenly difficult when they transition from studying mechanics to the world of waves. This happens because […]

I’m Ken Kuwako, your Science Trainer. For me, every day is an experiment! Have you ever heard of a machine that unravels the mysteries of the universe and matter by whirling invisible particles at breakneck speeds? Its name is the “Cyclotron.” While it’s a staple in high school physics textbooks, the sheer scale of this […]
