La trayectoria de un conocido químico teórico se utiliza para mostrar cómo, en 4 décadas, los desarrollos de teorías, programas (algoritmos) y de la tecnología computacional nos permiten en la actualidad el estudio confiable de la estructura electrónica de sistemas cuyos tamaños los hacían prohibitivos hace 40 años. Se señala y enfatiza que la dificultad central en el estudio teórico de la Química reside en que, en todas los escalas, se trata de un problema de muchos cuerpos cuya solución y comprensión siguen siendo un reto científico no resuelto y fascinante.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[A review of the methods developed within Theoretical Chemistry to study matter in many spatial and temporal scales is presented. The scientific career of a well known theoretical chemist is used to show how the astonishing advances that have been achieved in four decades in the development of theories, codes (algorithms) and computer technology allow nowadays the reliable study of the electronic structure of systems whose sizes were unmanageable forty years ago. It is emphasized that the central difficulty in studying Chemistry from a theoretical perspective is that, in every scale, one deals with a many-body problem whose solution and comprehension are still an unsolved and fascinating scientific challenge.]]></p></abstract>
