内容説明
GENERAL INTRODUCTION TO THE ETTORE MAJORANA INTERNATIONAL SCHOOL OF CLIMATOLOGY The "Ettore Majorana Centre" for Scientific Culture, founded at Erice in 1963 by prof. Nino Zichichi, pursues the fundamental aim to create in Europe a cultural forum of high scientific standard, which can allow young research workers to appreciate current problems of major interest in the various fields of scientific research. , Since the beginning, its International Schools (over 70, today) have actively worked in disseminating scientific culture produced at the most advanced frontiers of human knowledge, spanning varied domains from biology to nuclear physics, earth sciences, meteorology, architecture, medical sciences and so on, Recently, in 1979, the International School of Climatology has been created with the purpose to organize post-doctorate cour ,;es, in which outstanding and up-to-date outlooks, theories and results in the climatic field must be presented in didactic form. Climatic variability was the subject of the first Course, in that climatic changes represent one of the most exciting phenomenologies to study; in fact, even if the climate has changed many times in the past, so making it reasonable to as sume that it will do so in the future, it is still not easy to understand the above mentioned changes from an hydrodynamical point of view.

内容説明
In this book two ethical systems are described in the language of mathematics. Ordinarily mathematics is thought to be a science of quantity. Indeed, manipulation of quantities constitutes much of mathematics. Elementary applied mathematics deals with reckoning and measurement, where concrete quantities are objects of attention, such as counting sheep or weighing corno But the operations on these quantities are performed with the help of symbols, from which concrete referents have been 'abstracted out': 3 + 5 = 8 regardless of whether the symbols stand for numbers of sheep or tons of corno Thus, the first principle that exhibits the power of mathematics is abstraction. It is one ofthe three pillars on which the edifice of mathematics rests. Another pillar is precision. Ordinarily, man communicates by words. W ords serve communication to the extent that they refer to things, events, states of affairs, feelings of the speaker, and so on. These are the meanings attributed to words. Communication is successful to the extent that the meanings coded upon words by the speaker correspond to the meanings decoded by the hearer. As is weH known, the degree ofthis correspondence varies enormously in different contexts of discourse and with the back grounds or attitudes of the speakers and hearers. Mathematics is a language in which the meanings ofthe symbols (the 'words' ofthis language) are absolutely precise. This precision is achieved by abstraction. Abstract terms are defined by their relations to other terms and by nothing else."
