This file includes the lab manual write-up for the Au nanosphere and nanorod photoabsorption and scattering Lab experiment for the 2nd year Experimental Contemporary Physics Lab Course. In addition, several handouts are provided along with some additional information for instructors. This work was supported in part by by NSF Awards: ECCS #0701703, DMR #0707740 & DMR #1105121. The experiment can readily be upgraded to an advanced lab by giving more responsibility to the students for lab setup (give them an optical breadboard and parts) and by asking for more in-depth analysis and questions which require more knowledge and experimental skills to answer.

The American Mathematical Society (AMS) was founded in 1888 in order to further mathematical research and scholarship. Since that time, they have embarked on a number of outreach programs designed to educate the public about the importance of various mathematical endeavors. In the past several years, they have been developing the AMS Books Online website, and it's quite a resource. The works were all originally published by the AMS, and they can be browsed by author or subject. The subject headings include analysis, general interest, logic and foundations, and number theory. Users can download individual chapters from each book, and there are currently over thirty books available on the site. Visitors should make sure and check back, as there are plans to add books to the site periodically.

The National Oceanic and Atmospheric Administration's (NOAA) polar-obriting satellites monitor the ozone levels around the globe. The ozone layer acts to protect life on Earth by blocking harmful ultraviolet rays from the sun. The "ozone hole" is a severe depletion of the ozone layer high above Antarctica. It is primarily caused by human-produced compounds that release chlorine and bromine gases in the stratosphere. NOAA scientists reported that the 2006 ozone hole in the polar region of the Southern Hemisphere broke records for area and depth. In this animation, the POES satellite sensors document the change in the ozone hole over Antarctica. In the critical layer of the atmosphere between 8 and 13 miles, nearly all of the ozone has been destroyed. However, large declines in the ozone hole, such as the one in 2006, are common year-to-year variations caused by Antarctic stratosphere weather fluctuations. Overall, the ozone hole is estimated to decrease annually very slowly in area by about 0.1 to 0.2 percent for the next 5 to 10 years.

In this activity, developed by the Lane Community College MAPS GIS Program, students are asked to investigate the distribution of Chinook salmon in the Columbia River basin using GIS technology and web-based maps. The objectives of the lesson are for students to be able to "use GIS to investigate historic changes in salmonid habitat, understand the factors affecting fish habitat, and improve map skills and problem solving." On the site, visitors will find a link to the student activity, some introductory material about GIS and the web-based viewer used in this lesson. The link to the actual data leads visitors to the wrong map, but you can access it by clicking here. This is an excellent activity for high school or early undergraduate students for hands-on work with GIS and population ecology.

This printable sheet is an excellent reference tool for geometry students. It details the formulae for finding the area, volume, and surface area for a variety of two- and three-dimensional shapes and includes an illustration of each that shows which measurements are important to the calculation. Presented are: areas of polygons (square, rectangle, parallelogram, trapezoid, circle, ellipse, triangles); volumes of polyhedra (cube, rectangular prism, irregular prism, cylinder, pyramid, cone, sphere, ellipsoid); and surface area (cube, prism, sphere).

Where previously in Part 1 we covered the basics of program design and analysis and the usefulness of design patterns, in this part in this series of articles we develop models for programs that are more general than source code. Why not use the source code directly? First, there are many different types of source code - assembly languages, C code, and so on - but we can use a single model to describe all of them. Second, once we have such a model, we can perform many useful analyzes on the model more easily than we could on the source code.

This report describes the results of a major United States Geological Survey (USGS) geologic and oceanographic study of the Gulf of the Farallones, adjacent to the San Francisco Bay region. The first of its kind, the investigation was intended to establish a scientific database for an area of 3,400 square kilometers (1,000 square nautical miles) on the continental shelf for the purpose of evaluating and monitoring human impact on the marine environment. Topics include techniques and technology used in the investigation; oceanography and geology of the Gulf of the Farallones; biology and ecological niches; and issues of environmental management. There is also a list of supplemental reading materials and a glossary. The report is available in two versions: a shorter version for a general audience, and a more technical long version that is also available as a CD-ROM.
