Preface to the English edition
The book is based on the English translation of the Russian book «
Osnovy kosmomikrofiziki » (Basics of cosmoparticle physics), which
is used as a textbook for the course “Introduction to cosmoparticle
physics”, given during the last two decades to 5th year students of
National Research Nuclear University “Moscow Engineering Physics
Institute” (MEPhI), specialized in physics of elementary particles.
The aim of this course is to present the general trends of development
of modern cosmology and particle theory that lead to foundation of
cosmoparticle physics as the new field of science, studying fundamental
relationship of macro- and micro-worlds.
During the last decade the development of astroparticle
physics, precision cosmology and collider physics has been
progressing so rapidly that it may be now meaningless to review
all the directions of these studies in a comprehensive and self-
consistent way. The Virtual Institute of Astroparticle Physics
(VIA) created in 2007, now incorporated into the structure of
APC Laboratory (Paris, France), and operating on its website
http://viavca.in2p3.fr/site.html provides online the first hand information 
about the current progress in this field, so that the interested reader
can enter this site, get acquainted with the huge library of records of
previous videoconferences with VIA lectures, online VIA transmissions
from various conferences, colloquiums or seminars. He/she can also 
participate in an interactive regime online in all such events.
On the other hand, sometimes this progress passes by important
experience of earlier works and it is the aim of this book, presenting
the subject in its historical development, to fill in such gaps of the
common knowledge.
The ideas and methods of cosmoparticle physics, the nontrivial cross-
disciplinary links, arising in its research are to be developed in the full
body of this science, being the great challenge for this Millennium. I
can only express the hope that fundamentals of cosmoparticle physics,
here discussed, could play the role of proper cornerstones on which
this great future science will be built.
I am grateful to Victor Riecansky of Cambridge Intrenational Science
Publishing for cooperation in the work on the text of the manuscript.
