Throughout the years of reading and studying I have read many books of the French
encyclopedic series “Que sais-je?” . Each book of the series consists of about 128 pages
and deals with a particular subject or field of study and is written by a specialist . The number
of books I’ve read in this series amounts to about one hundred , books related to various

a good overview of the subject , while the “Que sais-je?” series delves deeper into the
subject and gives more advanced details with mathematical proofs and equations when
