Created by the Center for Nanotechnology Education and Utilization at Pennsylvania State University this Power Point presentation discusses top-down nanofabrication and its basic steps. These steps are then broken down further and examined â steps included are deposition, pattern transfer, etch more
This site, authored by Erik Francis and hosted by Alcyone Systems, is a dictionary of physics and astronomy. Users can look up laws, rules, terms and constants related to physics in pages listed by letter. The site is not a complete reference, but it is a useful resource for introductory physics.
This web page, authored and curated by David P. Stern, provides information and a graphical exercise for students regarding the interaction between magnetic field lines and a plasma. The activity involves tracing a typical interplanetary magnetic field line, dragged out of a location on the Sun by t more
This series of web pages, authored and curated by David P. Stern, gives an elementary discussion of cosmic rays, followed by sections on high energy particles in the universe and high-energy particles from the Sun. It describes the existence particles whose velocity approaches that of light, their p more
This resource describes the rocky intertidal habitats of the Monterey Bay National Marine Sanctuary and their biological diversity, distribution patterns, temporal changes, links to other habitats and assemblages, and management issues. Supporting materials include photos, tables, figures, and in-te more
This United States Geological Survey site focuses on water and its properties. The site contains activities for teachers and students, along with pictures, data, maps, and an interactive center where users can give opinions and test their water knowledge. Unique aspects of this site include the sect more
This is one of a series of animations that were produced to be part of the narrated video shown in the HoloGlobe exhibit at the Smithsonian Museum of Natural History and the Earth Today exhibit at the Smithsonian Air and Space Museum. This particular animation was not used in the final video.
This series of animations (animations 107, 1416, 1417, and 1418) show sheets of magnetic flux undergoing velocity perturbations. The conditions for each simulation are outlined within the video.
