In this blog post, I’ll share my honest thoughts on how time transforms the grief of parting ways with a loved one. Breakup. It was a word I’d heard countless times in romantic movies and love songs, but to me, it felt strangely unfamiliar. That’s because, in my twenty-odd years—a life not all that long—I had never experienced a heartbreaking breakup. So I had absolutely no idea what a...
In this blog post, we’ll explore why altruistic behavior evolved and persisted despite the selfishness inherent in human nature, using group selection theory. In our society, altruistic acts such as donating blood or cleaning up alleys are commonplace. However, viewed through the lens of natural selection, this is nothing short of a mystery. This is because altruistic individuals help...

In this blog post, I’ll explore the history of the atomic concept and the significance of modern atomic models, starting with a question that came to mind while grilling pork belly. Sizzle~ Mmm~ Ah, it’s truly a joy to eat this no matter when (tears of joy). I just finished grilling and eating pork belly, and now that I’m sitting at my desk, the savory scene is still fresh in my mind...
In this blog post, I’ll take a lighthearted look at the reasons behind laughter and empathy through my personal experiences. To be honest, this post began with a somewhat academic curiosity.
