Experiments with Everyday Objects: Science Activities for Children, Parents and Teachers - K... Book

I first read this book in 1974 and the effect it had on my view of knowledge has persisted ever since. What often passes for knowledge is often mere familiarity or recognition rather than the deep understanding that this book exemplifies. I resolved then that I would judge my level of attainment by the extent to which I could explain a concept to someone else. It was much later that I found out this approach is known as the Feynman Technique. I've since added other metrics such as economy of expression and use of memorable phrases and diagrams. In short, Asimov's simple concept for this book became something of a foundation for my future learning.
