Oswald's Midnight Press Conference
The midnight press conference of Oswald held on the evening of November 22, 1963. The video shows Jack Ruby at the back of the room.
Students examine images of galaxies and learn to recognize the various shapes used in the Hubble classification system. They can follow the site independently, using a worksheet that prompts them to answer questions in the text, then take a java "quiz" that requires them to place various galaxies in their correct positions on the Hubble "tuning fork." There is some supplemental material about galaxies and Hubble's observations.
Pollen Bots Activity
This activity visits the Japanese Weather Site that uses pollen monitoring robots as part of a remote sensing system in Japan. The robots collect current pollen counts in Japan.
Remembering Jim Crow
Remembering Jim Crow is a companion to a radio documentary, and examines the system that, for much of the 20th century, barred many African Americans from their rights as U.S. citizens. Read personal histories of segregation. See a sampling of Jim Crow laws. Learn how African Americans fought economic hardships imposed by Jim Crow and how they built social institutions to combat segregation.

Water management in Urban Areas
Master course on design and planning of the urban water management system. It deals with fluxes and processes in water and soil. Furthermore, aspects of water management policy development are discussed.
Advanced semiconductor devices are a new source of energy for the 21st century, delivering electricity directly from sunlight. Suitable semiconductor materials, device physics, and fabrication technologies for solar cells are presented in this course. The guidelines for design of a complete solar cell system for household application are explained. Cost aspects, market development, and the application areas of solar cells are presented.
This resource consists of a Java applet and expository text. The applet is a simulation of the fire process, an interacting particle system consisting of a rectangular lattice of "trees". At each discrete time unit, each tree is either on green, on fire, or burnt. A tree on fire at a given time can catch neighboring trees on fire at the next time unit. The probabilities of fire spread can be varied.
Tsunamis harbor an element of surprise: In the deep ocean, tsunami waves pass unnoticed beneath boats, yet they rise to dangerous heights near shore. How do tsunamis work? What was the worst tsunami in recorded history? How does a tsunami warning system work?
STS-135 Centennial of Naval Aviation Message
STS-135 Commander Chris Ferguson and Pilot Doug Hurley record a special message to commemorate the centennial of naval aviation.
The Power of Revolutionary Thinking: What Today's Scientists Can Teach You About Driving Innovat
“You’ll be on your way up!
You’ll be seeing great sights!
You’ll join the high fliers who soar to high heights.”
While Dr. Seuss may not have been a direct inspiration, “Oh, the Places You’ll Go!” seems especially suited to these four “brainy and footsy people” with exceptional re
Worldwide Amphibian Declines
AmphibiaWeb is an online system enabling anyone with a Web browser to search and retrieve information relating to amphibian biology and conservation. This site was inspired by the global declines of amphibians, the study of which has been hindered by the lack of multidisplinary studies and a lack of coordination in monitoring, in field studies, and in lab studies. We hope AmphibiaWeb will encourage a shared vision for the study of global amphibian declines and the conservation of remaining amphi
This is a project to develop a document for teaching graduate econometrics that is "open source", specifically, licensed as GNU GPL. That is, anyone can access the document in editable form, and can modify it, as long as they make their modifications available. This allows for personalization, as well as a simple way to make contributions and error corrections. The hope is that people preparing to teach econometrics for the first time might find it useful, and eventually be motivated to contribu
Mark Ratliff, Princeton University: Collaboration Tools at Princeton PDF
Lunch 'n Learn presentation: New forms of electronic collaboration promise to ease the sharing of information and ideas. These technologies reduce the barriers to participation and increase the efficiency with which information can be produced and exchanged. The University is now making available a new set of collaboration tools. This talk will introduce three of these tools and discuss their primary features, most appropriate uses, and how to begin working with each. Mark Ratliff, Princeton's
The American Jury: Bulwark of Democracy
"The American Jury: Bulwark of Democracy" is a project of the Constitutional Rights Foundation Chicago and is the national expansion of "The American Jury: Past and Present," conducted in Illinois during 1998-1999. Beginning with a two-week institute in July 1999, "The American Jury" focused on the jury system in the United States. its role in American legal, social, and political life; its origins and history; its adaptations to changes in law and American society; its strengths and limitations
Multilingual portal for free and open content courses and tutorials that people can benefit from in daily life. Educators can also add their own educational content to the system. The content at the moment consists mainly of language and computer related material. Not all content is multilingual.
Foucault Pendulum Model
The EJS Foucault Pendulum model displays the dynamics of a Foucault pendulum. The simulation is designed to show the dynamical explanation of why precession of the Foucault pendulum is slower at lower latitudes. The simulation shows simultaneously the motion with respect to the inertial coordinate system, and the motion as seen from a co-rotating point of view.
"Uchuhiko" (Japanese for Space Flight) is a wrapper for NASA/JPL's online Solar System Simulator running with both, QVGA and VGA Pocket PC screens. When you select date and time, view-to object (left combo box) and view-from object (right combo box) plus a field of view, Uchuhiko will download a computed and rendered image from the Solar System Simulator server. Tap and hold on a downloaded image to confirm settings. Simulate almost any exciting phenomena in the solar system by simply providing
Thinking About Politics: American Government in Associational Perspective
The goal of this textbook is to provide students with a comprehensive survey of the American political system and with a framework for analyzing its processes and functions. It will appeal to instructors of introductory American government courses who wish to take students beyond a traditional institutional orientation. Throughout the text, the various dimensions of American politics are integrated into an analytical framework designed to stimulate thoughtful understanding of the political world
