• Sommario/riassunto: Here, numerous winners of the Wolf prize from all chemical disciplines provide an overview of the new ideas and approaches that will shape this dynamic science over the forthcoming decades and so will have a decisive influence on our living conditions. This glimpse of the future is naturally based on the findings granted us by the rapid increase in chemical research during the 20th century. It may be said that a silent ""revolution"" took place, the positive results of which are still not fully predicted. For example, chemists in research laboratories nowadays are able to develop drugs
