I’m Ken Kuwako, your Science Trainer. Every day is an experiment. When you hear the word “capacitor,” what comes to mind? Most people vaguely know that it’s a component that stores electricity. But far fewer have ever seen what’s actually happening inside one. This time, I used a simulation tool called GeoGebra to visualize the […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment. Here are two tuning forks placed face-to-face. Strike just one of them, then immediately stop its sound by touching it with your hand. The room should be silent. Yet somehow, you can still hear a tone ringing out. Behind this curious little phenomenon lies […]
