Listening to the shape of a drum

A drum vibrates at distinct frequencies. These frequencies are related to the eigenvalues of a differential operator called the Laplacian. Mathematicians are interested in knowing how much geometric information about the domain (the surface of the drum) can be retrieved from the eigenvalues.     

下午，和苏格拉底听一首歌

乔布斯说,我愿把所有科技换成和苏格拉底相处一个下午。我们每一个人,是否也该沉静下来,和苏格拉底一起,喝杯下午茶,听一首歌,寻找那些藏在旋律中的真理与智慧呢?就这么一辈子(节选)演唱/江美琪花刚刚开过玫瑰有成为玫瑰的理由人就只有这么一辈子怎能不到秋天就凋落云刚刚飘过

Listening to Mothers II as a Catalyst

The Listening to Mothers II report is not only a document; it is a tool that is accessible to childbirth educators. By becoming familiar with its contents, educators can use the information to help expectant parents think about options available to them and inspire them to use evidence-based information as they make choices for the birth of their child.     

倾听学生的沉默之“声”

学生的沉默是指在特定的教学情境中学生静默无语的态度及行为。不同教学情境下,学生的沉默至少呈现出三种不同的样态,即受控性沉默、抗拒性沉默和建设性沉默。教师必须对学生的沉默做出适切的回应,然而在当下的教学中,教师对学生沉默的回应却呈现出随意性、简单化和非伦理化的倾向,由此遮蔽了学生沉默的教育性价值。笔者认为,倾听学生的沉默之"声",是凸显学生沉默的教育性价值的应有之举,其意义至少表现为:学生的沉默权获得尊重、学生成长的契机得以彰显、和谐的师生关系成为可能。     

倾听鸟儿歌唱

科学家们早就注意到公的斑胸草雀在它们独处时和附近有一只（可能成为配偶的）母雀时的鸣叫声有着细微的差别。为研究这一现象，有些研究人员决定把注意力集中在听到公雀鸣叫的母雀的反应上。他们竖起了一个长长的鸟笼子，在笼子两头各安上喇叭。一边播放公雀独处时唱的歌；而另一边则播放公雀专为某只母雀唱的歌。     

讨论出真知

Resonant frequencies of a piezoelectric drum transducer

This paper presents a piezoelectric-metal structure called a drum transducer. An equation for calculating the resonance frequency of the drum transducer is obtained based on thin plate elastic theory of piezoelectric and metal material combined with the Rayleigh-Ritz method. The finite element method （FEM） was used to predict the excitation frequency of the drum transducer. To verify the theoretical analysis, the input impedance characteristic of the drum transducer was measured using an experimental method. The results obtained from theoretical analysis were in very good agreement with those from the FEM and experimental results. The effect of geometrical changes to the thick-walled steel ring of the drum transducer at the first resonance frequency is also described. The calculated results were found to be in good agreement with the FEM results. The results indicate that the first resonance frequency of the drum decreases with the increasing inner diameter of the thick-walled steel ring.     

Listening to Student Voices

This study explores the perspectives of rural and suburban adolescents on the nature of schools, teaching, and leadership that influences learning. Middle and high school students with and without disabilities offer relevant insights to educators who are seeking to promote greater engagement, community, and success in their schools. Results suggest that student voices can be a powerful tool for school improvement.
