Throughout this book, we discuss some open problems in various branches of
science, including mathematics, theoretical physics, astro-physics, geophysics
etc. It is of our hope that some of the problems discussed in this book will
find their place either in theoretical exploration or further experiments,
while some parts of these problems may be found useful for scholarly
stimulation. The present book is also intended for young physics and
mathematics fellows who will perhaps find the unsolved problems described here
are at least worth pondering. If this book provides only a few highlights of
plau-sible solutions, it is merely to keep the fun of readers in discovering
the answers by themselves.Comment: 139 pages, many figure
