近来关于交叉科学的讨论越来越多,中国科学院和高等学校建立了多处交叉科学研究 中心。人们谈论着“一级学科”的交叉、自然科学和社会科学的“大交叉”、社会科学和 自然科学的“联盟”甚至“融合”。其实,学科交叉并非新话题。在1984年中国科学院拟 议设立支持基础研究的“院内”科学基金时,笔者就参与起草过“大交叉”的申请指南。 多年来,笔者对自然科学内部某些角落的交叉,有过一点实践,对“大交叉”时有所思

《科学观察》( Science watch)中所列举的最热 门课题(即由SCI引用率最高的论文所确定的前沿领域),可以看到近一年来(1989 1999.8)在世界范围内,物理学、化学、生物学和医学四大学科中哪些课题或领域处于最 前沿或属于最热门的范畴(引用率进入前10名),并可从统计数字的变化来分析各学科前 沿领域热门课题的发展趋势 物理学 近一年来,理论物理中对超弦理论的研究无疑在整个物理学的热门课题中占据着绝对的主 导地位,其引用率在一年的连续6次统计中,没有一次不进入前10名

从《费曼物理学讲义》的诞生过程,介绍费曼教育思想的要点指出基础物理 学课程的主要目的,并不是为后续课程的连接,为将来的具体应用做准备,或者向学生们 展示物理学发展的“窗口”;必须注重最基本的内容,避免不适当地追求新“花样” 关键词费曼;物理学

This vertical view shows the complex caldera at the summit of Olympus Mons on Mars, the highest volcano in our Solar System. Olympus Mons has an average elevation of 22 km and the caldera has a depth of about 3 km This is the first high-resolution colour image of the complete caldera of Olympus Mons. The colour image was taken from a height of 273 km in orbit 37 by the High

SPIRIT UPDATE: Spirit probes deeper into 'Clovis'outcrop-sol 209-218, August 23,2004 Spirit continued work over the past nine sols at a rock called \Clovis.\ The rover used roscop its rock abrasion tool, microscopic imager, alpha particle X-ray- spectrometer,and Mossbauer spectrometer to probe deeper into the history of this rock. Clovis is the most altered rock encountered by Spirit to date. It is part of a rock outcrop located on the\West Spur\ of the \Columbia
