I've had uncertain knowledges about science in general. So I couldn't explain wonders of science and nature properly to my son. And thanks to this book, I've become able to do the task better than before.
Chapters about electricity and electronics were interesting in particular. For instance, I could understand what "one-seg" is and what's the difference between cellphones and PHS.
