3.3 Mixing different forms of data: disjoint union of sets
This unit will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.

Recognizing Trees as Providers and Inspiration for Our Lives
Sponsored by the School of Forest Resources, the College of the Environment, and the Lockwood Endowment for Program Enhancement, the lecture addressed one of the greatest challenges of our new century—how to ensure that forests, which sustain human, animal, and plant communities worldwide, thrive and nourish both the livelihoods and spirits of future generations. Nalini Nadkarni , Faculty Member, The Evergreen State College shared her vision of how fostering deeper human relationships with tre
A Dollar as Good as Gold [Statement and testimony before the Subcommittee on Domestic Monetary Policy and Technology, March 17, 2011] Since the expansive Federal Reserve program of quantitative easing began in late 2008, oil prices have almost tripled; gasoline prices have almost doubled. Basic world food prices such as sugar, corn, soybean, and wheat have almos

Bestanden op een eenvoudige manier centraliseren op school : Stappenplan Een hindernis bij gebruik van voorleesssoftware (Sprint, Kurzweil 3000) voor kinderen met dyslexie is het tijdig aanleveren van de digitale bestanden bij de leerlingen die het nodig hebben. Bestanden “uitdelen” met een …

GSC-IS Version 2.0
The Government Smart Card-Interoperability Specification (GSC-IS) was released June 27, 2002. Developed in part by the National Institute of Standards and Technology, it provides an overview of the GSC architecture and discusses "solutions to a number of the interoperability problems associated with smart card technology." The main sections of the document offer details about the GSC architectural model, access control model, basic services interface, virtual card edge interface, card capabiliti
Laboratory for Atmospheric and Space Physics
A participant in the U.S. space program since the 1950s, the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado conducts research in atmospheric and planetary sciences, develops space instrumentation, and creates computer information systems. Through the extensive Tour, visitors can learn about LASP's assistance in unmanned robot spacecraft missions and its involvement in the International Solar Terrestrial Physics (ISTP) program. Students can read about experiment
Backyard Jungle
Created by Forum One Communications and funded by the Corporation for Public Broadcasting, Backyard Jungle is a kid-friendly Web site where members can upload photos, drawings, and descriptions of their own backyard or other natural area to share with an online community. Membership registration is straightforward and free of charge. While Backyard Jungle does not include any formal lesson plans or educational activities, it offers kids a fun incentive to explore and communicate about their natu
ANWR Technology
Drilling for oil in the Arctic National Wildlife Refuge (ANWR) in Alaska has been a topic of debate for many years. Although initial exploratory drilling has not yet been authorized by the government, this site presents some technologies that could eventually be used to find and extract oil without damaging the land. Nine articles describe different drilling methods, spill prevention tactics, exploration techniques, and more. One topic is 3D reflective seismic technology, which is used to help a
Battelle: Technology Forecasts
Battelle Memorial Institute works with the government and industry to develop new technologies and products. In the course of this work, Battelle has compiled several technology forecasts that speculate about what will be common in the years and decades to come. These predictions range from 2005 to 2020, and many of them are quite interesting. Concepts such as nanomachines, "personalized public transportation," and genetaceuticals are defined, and their use in society is explained. Only time wil
Galaxies
This Topic in Depth presents the science and research of galaxies. First, the University of Cambridge offers clear, logical descriptions and images of the Milky Way, spiral and elliptical galaxies, clusters, and dark matter of the Universe (1). Users can also find educational tutorials on many other cosmology topics. Next, the Space Telescope Science Institute's "Galaxies Galore, Games and More is a learning module designed to allow elementary students to use their observational skills, recogniz
Problems to Enjoy
Problems to Enjoy presents an enormous selection of mathematics problems for middle and high school students. Teachers will find it especially useful; divided into four categories and three grade levels, the problems are easily searchable. Eventually, the site's creators hope to "build up a comprehensive library of problems in a format that is simple to access, download and customize." The collection is already quite substantial. Number problems, algebra, geometry, and statistics are the main to
METRIC Math
Developed by individuals from the Mathematics Department and the Chemistry Department at the Imperial College in London, METRIC Maths aims to help students improve their math skills and knowledge. Visitors can download for free the Java-based program, which is geared towards advanced secondary level mathematics and as preparation for transitioning to University level mathematics. The program provides students an opportunity to "investigate mathematical ideas using METRIC's explorations," practic
Young Engineers: Tomorrow's Ideas Today
This is the official homepage of Young Engineers, "a UK educational charity whose purpose is to inspire young people to recognise the importance and excitement of a career in engineering." Being tailored to British and other UK students, the site contains information on engineering competitions in the region, including coverage of past competitions and details on entering future events. Despite having substantial resources for prospective engineers in the UK, there is plenty of additional materi
Deep Content: Guide to Effective Searching of the Internet
This outstanding website is, without question, one of the most comprehensive online resources for learning efficient Internet search techniques. The guide begins with some fairly non-technical background about the Internet and explains why searching such a massive amount of information is more complex than it seems. The general process used by search engines to rank webpages is described. After covering the fundamentals of search engine operation, the guide discusses some best practices to use w
"Just the Maths"
Developed by a retired mathematics professor from Coventry University, this website "is a collection of separate units, in chronological topic-order, intended to service foundation level and first year degree level courses in higher education, especially those delivered in a modular style." Although there are separate sections for students and teachers, both contain essentially the same information except for the format of the material -- printable pages with slightly more detailed explanations
