This collection of concise biographies of scientists has been an important and attractive feature of the CHILDREN'S DIGEST for more than five years now. The first set of articles published by the Pauline Publications, Mumbai, entitled "INVENTORS AND DISCOVERERS" has been well-received by the public. The letters being received at the Digest from schools and homes all over India also testify that the series makes for one of the more popular items of the magazine. Each article has been written very carefully keeping in mind its readers. The narration is direct and lucid, story-like, with touches of humor, so as to interest the young, both boys and girls of the high school and higher secondary levels. The biographies are intended to help our youth in better understanding science with reference to the extraordinary lives that were given to nurture it. A perceivable common thread that runs through those great lives is spun from a spirit of adventure in the realm of thinking and individual initiative in the search for knowledge. This book will help young people to imbibe this spirit too.
