One other reason why many chemists and biologists are skeptical about parity violation and other subtle physical effects, is that the breaking of symmetry can be realized rather simply in the chemistry laboratory. According to Meir Lahav, one of the best known researchers in the field, breaking of symmetry is not the problem. He means by that, that the problem is rather the propagation and amplification of chirality. In sidebox 3.3 he summarizes some of the main concepts in particular, he considers crystals as agents of symmetry breaking (Weissbruch et al, 2003). 

In this chapter the question of homochirality has also been considered according to Meir Lahav breaking of symmetry is not the problem. I do not know how many scientists would agree with him, but it is certainly true that in the laboratory chiral compounds can be obtained starting from racemic mixtures -and this by simple means, without invoking subtle effects of parity violation. Of course we do not know how homochirality really evolved in nature however, it is comforting to know that there is in principle an experimental solution to the problem. 

A number of colleagues were very kind and helpful with their advice. I would like to thank Antonio Lazcano, and Albert Eschenmoser, who in different ways helped me with their frank comments and Meir Lahav, Joseph Ribo, Jeffrey Bada, and David Deamer. Particular thanks are due to Dr. Pasquale Stano, whose help has been essenhal, particularly, but not only, with the bibliography also Rachel Fajella helped with the editing of some parts of the manuscript. I am also particularly indebted to Angelo Merante for the illustrahons and the formatting of the manuscript without him, the manuscript would shll be in my drawers. Last, but not least, I want to thank my students of the University of Rome 3, their positive feedback at the very early stages of the manuscript was very important.

With the appearance of this volume we are pleased to welcome two new members to our Editorial Advisory Board Marian M. Mikolajczyk (Polish Academy of Sciences) and Nikolai S. Zefirov (Moscow State University and Soviet Academy of Science). We also welcome Meir Lahav (Weizmann Institute of Science), who joined the editorial board with the appearance of Volume 19. We hope that these colleagues will help us keep in touch with stereochemical developments in Poland, in the Soviet Union, and in Israel, respectively. We also wish to acknowledge with thanks the advice received over the past decade from Professor Jan Michalski who is relinquishing his position on the Board.
