I’m Jack, a retired physicist and the author of many scientific papers published in international reviews. After many years spent in formulating mathematical models describing the physical word, at present I dedicate part of my time in creating word search and sudoku puzzles.

The idea of this blog is to present not only my books but also the most recent books that I’ve found on Amazon and that I’m glad to suggest to you.

This blog is open to the collaboration of any other author that would like to do.
