Finding Common Ground
Finding common ground helps students make informed decisions to conserve temperate forests in the United States and central China, habitat of the endangered giant panda. Through classroom activities, on-line simulations, and field investigations students learn about the important role temperate forests play in local and global ecosystems. Action steps culminate in a Class Conservation Action Plan. In the course of this curriculum students locate the biome in which they live, explore a local habi
Barrier Scattering model
The EJS Barrier Scattering model shows a quantum mechanical experiment in which an incident wave (particle) traveling from the left is transmitted and reflected from a potential step at x=0. Although the analytic solution to this standard problem is well known, its visualization shows how the incident and reflected waves form an interference pattern and how the incident wave penetrates the classically forbidden region when its energy is less than the barrier height height V0

Charge in Magnetic Field
The EJS Charge In B-Field model allows the user to simulate moving charged particles in two identical magnetic field regions separated by a zero magnetic field gap.

The EJS Helmholtz Coils Model shows a the magnetic field between two circular coils of wire. The default configuration, known as a Helmholtz coil, sets the separation distance D equal to the coil radius R. These values produce a nearly uniform magnetic field B between the coils.
Field day sponsored by USC
Several athletes cross the finish line of a 100-yard dash while men in hats measure their time during a USC field day held at Santa Monica. In the background a small crowd sits in the grandstands.
Field day between Pomona College and Occidental College
Pomona College and Occidental College athletes compete in a hurdles event during a field day [probably at Occidental College]. A line of men in hats stand all along the track cheering them on.
Field Notes: Human rights defenders speak
In this seventh 'Field notes' event held in conjunction with Human Rights Watch UK, frontline human rights defenders will discuss monitoring human rights violations in Nepal and Zimbabwe: their different personal experiences, methods of collecting and evaluating information and the ways in which they develop advocacy campaigns both locally and at an international level.

Intimate Strangers: Unseen Life on Earth
This PBS documentary provides an overview of the microbial world and offers an exciting glimpse into the field of microbiology. Meet scientists from around the world investigating the microbial world in diverse locations, from a termite's stomach to a hospital operating room to an African village, and even outer space. These programs - including The Tree of Life, Keepers of the Biosphere, Dangerous Friends and Friendly Enemies, and Creators of the Future - increase the microbial literacy of stud

The Visual Datasets text module discusses the concept of visual learning and presents some suggestions for ways to design learning environments that support students in developing visual literacy skills. Three visual datasets that can be used for problem solving activities in evolution, classification, development, and botany are included: Caminacules: A dataset of imaginary animals that can be used as the basis for a variety of problem-posing and problem-solving activities in evolution, classi
Microbial Genetics Construction Kit (?GCK)
A µGCK problem starts with a field collection of bacteria, either in a test tube or plated onto a petri plate. Each of the gray circles on the plate represents one colony. These colonies result from bacteria collected from the field. The colonies are of unknown genotype and phenotype, although all bacteria within a colony share a genotype and phenotype. µGCK includes several tools to help organize and analyze the data that are collected during an experiment. The Media Matrix window displays t
Heroes and Heroines
Teachers can use this lesson to introduce or examine in depth the concept of heroism through discussions of heroic actions and character.Students will look at images of military, religious, political, and everyday heroes and heroines and discuss their lives and the effects of their deeds. For the purposes of this lesson, heroes are defined as figures who have great strength and ability and are admired for their achievements. They may risk or sacrifice their lives for others or may be noted for s
Gerry Martin at a Seminar
Gerry Martin talks about the development of science and technology over the last ten thousand years. He illustrates his arguments with charts and glass instruments.,Gerry starts the seminar held at King's College, Cambridge, in April 2003, and then makes several interjections. At the end he summarizes much of his philosophy of historical change. Filmed by Alan Macfarlane. Lasts about 42 minutes.
Lecture on fieldwork in the Soviet Union, 1988-9
Public lecture given in October 1989 by Professor Ernest Gellner. He reflected on his year spent in the Soviet Union on the eve of the collapse of communism.,The lecture was given to a Cambridge Audience in the Rayleigh Lecture theatre in the Social and Political Sciences Faculty. Professor Gellner had flown in that morning from America. It was filmed, using a video 8 camera, by Humphrey Hinton. It was chaired by Dr. Alan Macfarlane. The video is unedited. The lecture lasts for about 65 minutes.
Fault-tolerant distributed shared memory on a broadcast-based interconnection architecture
This thesis focuses on the issue of reliability and fault tolerance in Distributed Shared Memory Multiprocessors, and on the performance impact of implementing fault tolerance protocols that allow for Backward Error Recovery through the use of synchronized checkpointing. High Performance Parallel computing systems that implement Distributed Shared Memory (DSM) require interconnection networks capable of providing low latency and high bandwidth and efficient support for multicast and synchronizat
