"100 Science Questions That 90% of Japanese People Can't Answer" Author: Wadai no Tatsujin Club Publisher: Seishun Bunko Price: 690 yen + tax Why doesn't a calculator make calculation errors? Why doesn't the "secret sauce" of an eel restaurant rot even after being used for 200 years? How do we know the distance to stars that are "tens of thousands of light-years" away? And many more questions that you've always wondered about but don't know the answers to. This book provides clear answers to everyday science questions that you can't answer even when asked by children! I've read a few pages, and it's in very good condition with no stains or writing. Thank you. #book #bunko #nature #science #novel #science #parenting #knowledge #science
