OM BOOKS INTERNATIONAL 365 Inventions That Changed the World

It is really very good book.

Good to read

Arranged in chronological manner although with some mistakes in the images shown e.g. an ammeter is shown for the description of volt meter. Over all very good as general information with some major miss outs like electric motor, generator, thermionic valve.

A good compilation of inventions, some huge, some silly but all interesting! My kid loved this book. Good quality paper and sturdy back cover. Illustrations are colorful and attractive for children. Easy to read font and font size.

Very interesting for children above 7 year. atlest you can divert them from blue light
