“Which transparent coin bank do you want?” I asked my son. “What’s the meaning of transparent, btw?” that was my real intention of asking him to make a decision. “let light pass through it,” he replied. Okay, he passed my formative assessment. He had replied “let light go through it”, which I think is not as scientifically rigorous. “Light travels in a straight line,” I persisted in my efforts to impart some Science knowledge. Need to move on to shadows once he internalizes this. It is important that he gets a transparent coin bank so that he can get a good dose of endorphins when he observes his coins piling up. Looking through my photos, I think transparency plays an important part not just in my professional life, but also during my leisure time. I love watching the locals at work whenever I go overseas. I can’t help wondering the efforts they must have put in in order to master their craft, whether they like their job, whether they are used to strangers staring at them. I love musing about the nature of work, and transparent windows help me indulge in this endeavour. https://diaperfinancingfund.blogspot.com/2025/09/psle-science-properties-of-materials.html
