Cryptology ePrint Archive
The International Association for Cryptologic Research (IACR) maintains this archive of nearly 400 research papers on various topics in cryptology. Contents date back to 1996, and new material is posted most weeks. Papers generally describe original theories about a certain topic, analyses of cryptologic methods, or proofs of specific equations. Anyone can submit their research for possible inclusion in the archive. There is not an extensive refereeing process, which allows authors to more quick
The TeraGrid: A Primer
A project of the National Science Foundation, the TeraGrid is "a multi-year effort to build and deploy the world's largest, fastest, distributed infrastructure for open scientific research." This paper, published in September 2002, describes the activities and ongoing projects that will ultimately lead to the project's completion. TeraGrid, as the name implies, is based on principles of grid computing. It will eventually consist of a massive network of computers spread out over several sites tha
Vienna University: Differential Geometry and Geometric Structures
Differential Geometry and Geometric Structures is one of six research units which comprise the Institute of Discrete Mathematics and Geometry of the Vienna University of Technology. From this website, visitors can read about members and their research activities and download select publications (in German and English). They have also developed some software, which is in German, for use in geometry courses in Austrian schools. The Picture Gallery offers a collection of world Map Projections creat
Observe an animation of metamorphic rocks forming
This interactive Earth science resource for middle and high school students demonstrates how heat and pressure beneath the surface of the Earth change igneous rocks into metamorphic rocks. Photographs accompanied by a short animation and text boxes illustrate how the igneous rock diorite is transformed into the foliated metamorphic rock gneiss. The mineral components of each rock are labeled. Students are able to use control buttons to play, pause, and move forward and backward through the simul
In this lesson, students model a bungee jump for a Barbie doll. They collect data in a table (number of rubber bands and jump distance), then create a scatterplot of the data, find its line of best fit, and write an equation of that line. Students go on to analyze the equation, noting its slope in relation to the data collected, and the meaning of the y-intercept. Since the distance to which the doll will fall is directly proportional to the number of rubber bands, the lesson provides a scenario
Microbes : too smart for antibiotics?
This lesson packet builds on a peer-reviewed article about antibiotic resistance in microorganisms. The packet contains discussion questions about the article, instructions for an activity about hand washing that uses fake, fluorescent 'germs,' and two handouts of ideas for student activities. The first handout is appropriate for general biology students, and the second is designed for advanced, AP, or first-year undergraduate students. In many of the activities, students create a product, such
The Need for Ocean Literacy in the Classroom - Part I : An overview of efforts to promote ocean lite
Society is largely ocean illiterate and a basic understanding of the key concepts needed for sound decision making on matters related to sustainability and the health of humankind is lacking. At present, a network of approximately 100 members of the ocean science and education communities are working together to make understanding the ocean part of the formal K-12 curriculum. The emergent consensus among the members of the group has resulted in a definition of ocean literacy that is supported by
This Java applet is designed to allow students to practice visualizing and calculating area and perimeter for figures formed by adjacent squares on a grid. After the student selects a size using a slide bar, the Java applet generates a random closed figure. The student enters values for the figure's area and perimeter, which are checked automatically. The applet limits figures to rectangles and generates two column comparisons of areas and perimeters for multiple figures. From the activity page,
Lotto or Life: What Are the Chances?
Students are naturally inquisitive about space science and the topics surrounding the existence of intelligent life in other parts of our Universe. Tapping into this curiosity, this lesson uniquely combines the concepts of astronomy and probability to have students use inquiry, problem solving, reasoning, and communication skills to compare winning the lottery with the likelihood of intelligent life existing elsewhere in the Universe. The site contains all of the information and materials needed
Teachers can direct students to this material to help them investigate a career as a zookeeper. Having students review this page can be an excellent precursor to a job-shadowing activity. The discussion board's set of questions and answers can be a helpful resource for an activity in which students produce a number of pertinent questions that should be asked of a zookeeper when investigating this field of work.
