The lecture uses little formalism and illustrates every notion by numerous pictures and diagrams. We thoroughly investigate a few significant examples of creating rod groups and symmetry groups of spiral mosaics from wallpaper groups. distinct translations of the Euclidean plane may correspond to translations, rotations and screws of the Euclidean space. In this dictionary axes of transformations are important since f.e. The relationship between these groups is given by means of an interpretation dictionary translating isometries of the Euclidean space into isometries of the Euclidean plane restricted to a stripe and further, into the inversive transformations of the Gaussian plane. However, rod groups are far less popular and symmetry groups of circular and spiral mosaics of the Gaussian plane were not so extensively investigated and popularised. The aim of the talk is to describe a relationship between frieze groups, wallpaper groups, rod groups and symmetry groups of circular and spiral mosaics.Īll is known about frieze and wallpaper groups and they were approached in many ways. Abstract for 17196įrom friezes and wallpapers to ornaments of rods and further to circular and spiral mosaics Authors: Bogumila Klemp-Dyczek Affiliations: Nicolas Copernicus University We shall make a brief survey of the collection, its academic value and to discuss works of particular interests in Dynamic Geometry.

The collection is a part of the Internet Archive which serves as a valuable source of intellectual capital for researchers and students alike. Abstract for 17150Īpplications of the Internet Archive to Dynamic Geometry Authors: Jen-Chung Chuan Affiliations: Department of Mathematics, National Tsing Hua University, Hsinchu, Taiwan 300Īs of this date, The Open-Access Text Archive contains 1,450,319 items. The Affiliations and feedback of the students to the course, as well as the expectation and prospect for the future are presented in the end of the paper.
All of those records present valuable experience for pre-service teacher's education.

The strong incentive to learn dynamic geometry and the skilled using of dynamic geometry software - Super Sketchpad after training gives us surprises and pleasure. First, the classroom teaching details is presented so that the situation of course is better understood, and the problems exposed in the practice are also shared in this paper, which deserve our reflection. This paper records our experience of teaching dynamic geometry course in 2008. Practice and think about teaching dynamic geometry course in Normal UniversityĪuthors: Jingzhong ZHANG, Xicheng PENG, Mao CHEN Affiliations: Central China Normal UniversityĪccording to the demand for modernization of education, combined with math education requirements of middle school, we provide the dynamic geometry course for students majoring in mathematics education, i.e., the pre-service teachers of mathematics, in Huazhong Normal University. Abstracts for Plenary Talks & Invited Papers Abstract for 16936 With the markup ready, first we apply some basic styles to the unordered list.
We start with some very basic markup a plain unordered list with a span element inside each of the list items: To get an idea of what we’ll be creating, have a look at the embedded CodePen demo below: HTML Markup

Although HTML5 Canvas and SVG might be more elegant solutions for building charts, in this tutorial we’ll learn how to build our very own donut chart with nothing but plain CSS.
