How to Send A Secret On A Postcard: Public Key Cryptography - March 3, 2010
Lunch 'n Learn presentation: Computers use an ingenious invention called public key cryptography to transmit secrets on the internet, even through public channels that can be observed by anyone. This talk will explain how public key cryptography works, without assuming any prior knowledge of math or computer science. We'll also find out why there was a big party in San Francisco on September 21, 2000. Further info: http://blogs.princeton.edu/itsacademic/2010/03/how_to_send_a_secret_on_a_postcard

Inside Theory-Aware and Standards-Compliant Authoring System
In their paper [14], Bourdeau and Mizoguchi foresaw a framework for ontology-based intelligent systems. Although it took longer years than their expectation, the ontology they have been developing is now released for evaluation with the help of the second author. Ontology building is a labor-intensive process and it is rarely perfect. Our enterprise is not an exception. The current ontology is still very preliminary because it has been completely reconstructed from the existing one with a few ne
NGO and citizen politics
The purpose of this course is to introduce students to the conceptual issues, theories, and debates concerning ‘civil society and new politics.’ Focusing on the domestic and global issues of ‘civil society and new politics’, the topics that will be covered in class include concept of civil society, social capital, engaging communities, associative democracy, global civil society in action, civil society and global governance, etc. Class will be conducted in a seminar consisting of lectur

Mrs. Matthews Centers for the week of September 27
The students in Mrs. Matthews science class have been studying plants this week. They have been learning the parts of a plant, parts of a flower, parts of a seed, and various jobs a plant has. The students work through six centers throughout the week. The centers include (1) an art activity about pollination (2) an A.R. book about pollination (3) several interactive websites about the growth of plants and how plants respond to light and gravity (4) an art activity about the life cycle of a

Light Years Measurement
Astronomers have more practical units of measurement, such as the light-year, to describe the vast distances between objects in the universe. Because light does not travel instantaneously—in a vacuum, light travels at a finite speed of about 300,000 km/s (186,000 mi/s)—it takes time for light to travel through the universe. One light-year is equal to the distance that light can travel in one year's time, which is nearly 10 trillion km. Thus, Proxima Centauri is about four light-years away. T
Great Circle – A Virtual Manipulative
Use a 3D globe to visualize and measure the shortest path between cities. This manipulative shows the great circle route and the great circle distance between a number of cities around the globe. Click and drag to rotate the globe.
To see the route and distance between any two cities on the map, simply click on the red dots representing the two cities. Two routes are shown. The green route is the smaller arc of the great circle containing your two cities. The approximate great circ

PLATO - A Culture of Innovation
On June 3, 2010, the Computer History Museum hosted a 6-session conference on the PLATO learning system. Session 1 was entitled "A Culture of Innovation: What Don Bitzer Wrought."
Session 1 Description:
The Computer-based Education Research Lab, where the PLATO system was invented, was a caldron of innovation. Out of that environment, new technologies grew and lives were changed. What was it about the environment that stimulated innovation? Bob Sutton, management guru and scholar of innovation,
PLATO - Innovations in Hardware

Session 2 Description:
Early discussions at the University of Illinois on how to use emerging computer system technology for delivering quality education quickly led to the formation of a very exciting demonstration project called PLATO. This project was a highly "mission oriented" effort and used
PLATO Learning System Software
On June 3, 2010, the Computer History Museum hosted a 6-session conference on the PLATO learning system. Session 3 was entitled "PLATO Software: Driven by a Clear, Compelling Challenge."
Session 3 Description:
The software architecture of the PLATO Learning System permitted high interactivity with hundreds of users and a TUTOR programming language that enabled faculty (and gamers) to write their own interactive graphics programs. These capabilities required close management of scarce system res
PLATO - Online Education & Courseware
On June 3, 2010, the Computer History Museum hosted a 6-session conference on the PLATO learning system. Session 4 was entitled "Online Education & Courseware: Lessons Learned, Insights Gleaned."
Session 4 Description:
Thousands of hours of courseware in dozens of academic disciplines were developed on the PLATO system, and deployed to thousands of students at levels from K-20. The open environment and sophisticated authoring tools enabled any interested and creative instructor to develop cours
PLATO - An Early Community of Multiplayer Games
On June 3, 2010, the Computer History Museum hosted a 6-session conference on the PLATO learning system. Session 5 was entitled "PLATO Games: An Early, Robust Community of Multiplayer, Online Games."
Session 5 Description:
Social gaming is the fusion of computer games and digital communities. Some of the earliest instances of this occurred on the PLATO system, and were made possible by the PLATO system's technological innovations as well as a sufficiently open environment to allow the developme
PLATO - An Early Online Community
On June 3, 2010, the Computer History Museum hosted a 6-session conference on the PLATO learning system. Session 6 was entitled "An Early Online Community: People Plus Computing Grows Communities."
Session 6 Description:
The developers of PLATO didn't set out to build an online community. So how did it turn into one? In 1972 few suspected that a human community could grow and thrive within the electronic circuitry of a computer. But two years later the world's first online community was flouris
