New theories for new instruments: Fabrizio Mordente's proportional compass and the genesis of Giordano Bruno's atomist geometry

The aim of this article is to shed light on an understudied aspect of Giordano Bruno's intellectual biography, namely, his career as a mathematical practitioner. Early interpreters, especially, have criticized Bruno's mathematics for being “outdated” or too “concrete”. However, thanks to developments in the study of early modern mathematics and the rediscovery of Bruno's first mathematical writings (four dialogues on Fabrizio's Mordente proportional compass), we are in a position to better understand Bruno's mathematics. In particular, this article aims to reopen the question of whether Bruno anticipated the concept of infinitesimal quantity. It does so by providing an analysis of the dialogues on Mordente's compass and of the historical circumstances under which those dialogues were written.     

DNA编码的模型分析

提出了适应DNA计算的DNA编码问题.对等码长的DNA编码问题的数学模型进行分析.以优化码长作为目标,分析了约束条件.以杂交反应为核心将约束条件分为基本约束和控制生化实验的约束,而控制生化实验的约束包含组合约束和热力学约束.控制移动不匹配的下值才能控制杂交反应,由此改进了移动距离.引入窗口距离解决了错配总量和分布的控制问题.

工学结合模式下经济数学课程改革的研究与实践

本文从研究高职院校经济数学课程教育目标入手,从经济数学课程内容体系改革、教材建设改革、教学方法和考核方式改革以及数学建模活动的开展等四个方面给出经济数学课程建设和改革的实施方案。     

高师数学教学实习的模式探索与研究

教育实习是师范教育实践教学的最重要部分,课堂教学实习是教育实习的首要内容。关于数学教学实习的模式,国内外也在积极地探索与研究,不断有一些新的模式出现,但是这些模式宏观性,共同性较多,而针对性、专业性的较少。为了适应教育发展与改革的需要,在多年数学教学实习经验的基础上,构建了高师院校数学教育专业"双循环"教学实习模式,以提高数学教学实习的效率和质量。     

工程数学教学的几点建议

The influence of Spinoza’s concept of infinity on Cantor’s set theory

Georg Cantor, the founder of set theory, cared much about a philosophical foundation for his theory of infinite numbers. To that end, he studied intensively the works of Baruch de Spinoza. In the paper, we survey the influence of Spinozean thoughts onto Cantor’s; we discuss Spinoza’s philosophy of infinity, as it is contained in his Ethics; and we attempt to draw a parallel between Spinoza’s and Cantor’s ontologies. Our conclusion is that the study of Spinoza provides deepening insights into Cantor’s philosophical theory, whilst Cantor can not be called a ‘Spinozist’ in any stricter sense of that word.
