| 中文简介: |  在约瑟夫·斯特凡学院举办的数学座谈会上，诺贝尔奖获得者哈罗德·克罗托爵士举行了盛会。该研讨会是与数学和物理学院，JožefStefan研究所以及纳米科学和纳米技术卓越中心合作举办的。 人类对天堂的敬畏已经驱动了人类的几乎所有方面文化和知识，并导致技术总体上产生积极影响，但有时产生消极影响。自伽利略认识到金星的相位提供了证实哥白尼日心系统并巩固其作为“科学之父”地位的证据以来，可以说是最积极的。从这一刻起，我们终于有了一种直接的哲学构想和语言，使人类能够确定什么是“真”。特别重要的真理源于人类对宇宙运作方式的详细了解的好奇心。这导致了天体物理学及其相关技术的发展。其中最重要的就是望远镜-从伽利略的原始设计到NASA推出的神奇的卫星发射设备。这些不仅使我们能够更清楚地观察到行星和恒星，而且还能够看到宇宙的边缘，并从恒星到恒星之间空间的占据者，对宇宙的各个方面进行了大量的发现。发生在恒星内部的过程。也许基于空间观测的最根本的进步导致了古典力学的发展，以了解行星和彗星的运动，并随之发展了微积分，这是数学上最伟大的成就之一。随着量子力学与光谱学一起发展，不可避免地我们应该开始研究天体第一热星以及冷彗星的原子和分子组成。随着射电望远镜的发展，非常冷的星际介质被认为是名副其实的潘多拉魔盒，充满了迷人而奇特的分子，尘埃颗粒以及一些令人费解的材料，构成了一些尚不确定的光谱特征。后者被称为1920年代首次发现的漫射星际带（DIB）。 |
| 课程简介: | The mathematical colloquium held at Jožef Stefan Institute hosted a distinguished guest Nobel laureate Sir Harold Kroto. The seminar was prepared in collaboration with Faculty of mathematics and physics, Jožef Stefan Institute and Center of excellence in Nanoscience and Nanotechnology. The age-old awe that man has had for the heavens has driven almost all aspects of human culture and knowledge and resulted in technologies with generally positive, though occasionally negative effect. Arguably the most positive have taken place since Galileo recognized that the phases of Venus provided the evidence that confirmed the Copernican heliocentric system and cemented his position firmly as the “Father of Science”. From this moment on we had, at long last, a straightforward philosophical construct and language which enabled mankind to determine what is and is not “True”. Particularly important truths have resulted from the curiosity that humans have had for a detailed understanding of the way Universe works. This led to the development of astrophysics and the associated technologies that have been spun-off. Not least of these has been the telescope – from Galileo’s beautiful original design to the fantastic satellite-born devices put up by NASA. These have not only enabled us to observe the planets and stars more clearly but we have been able to see to the very edge of the Universe and make a plethora of discoveries about all aspects of the Universe from the occupants of the space between stars to the processes occurring deep inside stars. Perhaps the most fundamental advance based on space observations led to the development of Classical Mechanics in order to understand the motions of the planets and comets and concommitantly the development Calculus, one of the greatest of Mathematical achievements. As Quantum Mechanics developed along with Spectroscopy it was inevitable that we should start to study the atomic and molecular composition of heavenly bodies - first hot stars as well as cool comets. With the development of radiotelescopes, the very cold interstellar medium was found to be a veritable Pandora's Box, full to the brim with fascinating and exotic molecules, dust particles and also some highly puzzling material responsible for some as yet unidentified spectroscopic features. These latter are known as the Diffuse Interstellar Bands (DIBs) first observed in the 1920s. |
