Measuring Health Disparities
Measuring Health Disparities is designed to be accessible to a broad audience of practitioners across all sectors of the public health workforce. In contains audio and interactive elements and focuses on some basic issues for public health practice - how to understand, define, and measure health disparity. The material is divided into four parts. Parts One and Two review what health disparities are, how they are defined, and provide and overview of common issues faced in measuring health dispar
Inquiring Minds: Fermilab
This sie features an introduction to elementary particles and forces in our universe, physics questions answered by Fermilab scientists, an interactive timeline illustrating the history of high-energy physics, links to other high energy physics sites, and more.
AlgTop7: The Klein bottle and projective plane
The Klein bottle and the projective plane are the basic non-orientable surfaces. The Klein bottle, obtained by gluing together two Mobius bands, is similar in some ways to the torus, and is something of a curiosity. The projective plane, obtained by gluing a disk to a Mobius band, is one of the most fundamental of all mathematical objects. Of all the surfaces, it most closely resembles the sphere. This is the seventh lecture in this beginner's course on Algebraic Topology, given by Assoc Prof N
AlgTop3: Two-dimensional surfaces: the sphere
After the plane, the two-dimensional sphere is the most important surface, and in this lecture we give a number of ways in which it appears. As a Euclidean sphere, we relate it to stereographic projection and the inversive plane. This is the third lecture in this beginner's course on Algebraic Topology. The lecturer is Assoc Prof N J Wildberger of the School of Mathematics and Statistics at UNSW.
Frontiers of Biomedical Engineering
The course covers basic concepts of biomedical engineering and their connection with the spectrum of human activity. It serves as an introduction to the fundamental science and engineering on which biomedical engineering is based. Case studies of drugs and medical products illustrate the product development-product testing cycle, patent protection, and FDA approval. It is designed for science and non-science majors.
OPSE 410: Biophotonics
An introduction to the interaction of light with biological tissues. Biophotonics for diagnostic and therapeutic applications will be discussed. Topics include propagation of light in turbid tissues, absorption, scattering, laser surgery, and optical rotation.
Introduction To Singapore Math
This is a brief introduction (slide show) to Singapore Math.
Essential Science for Teachers: Physical Science Session 3. Physical Changes and Conservation of Mat
What happens when sugar is dissolved in a glass of water or when a pot of water on the stove boils away? Do things ever really "disappear"? In everyday life, observations that things "disappear" or "appear" seem to contradict one of the fundamental laws of nature: matter can be neither created nor destroyed. In this session, participants learn how the principles of the particle model are consistent with conservation of matter.,The segment shows the interviewer trying to find out the student's id
Idaho Civil Rights Program: American Indian Emphasis Program (AIEP)
This site provides an introduction to the American Indian Emphasis Program, which provides sound program practices in administering the Idaho Civil Rights Program. The site features contact information and an overview of the AIEP's goals.
Remote engineering implies a new strategy of assessment?
When we spoken about remote engineering as a new methodology used in the cyberspace with the final goal of the teaching/learning improvement and cost sharing, we are obliged to approach all of the process sides. Assessment is one of these sides and there is considered the most powerful tool for illustration, in the qualitative and quantitative ways, the learners responds at educational objectives offered by the remote engineering learning environment. In the present paper the authors have the in
Biology of Plants

Space Time Travel
Black holes and travel at nearly the speed of light: Visualization of the theory of relativity. This site offers online papers, images, movies and paper models. The website presents computer simulations that provide "virtual experiences."The images and movies are correctly computed within the framework of the theory of relativity. They are carefully explained in an intuitive, non-mathematical way.
Ejs Normal Modes on a Loaded String Model
The EJS Normal Modes on a Loaded String model displays the motion of a light string under tension between two fixed points. The string is also loaded with N masses located at regular intervals. The number of masses on the string can be changed via textboxes.
DynaFit - (Bio)Chemical Kinetics and Equilibria
The freely available software package uses a nonlinear least-squares regression analysis to fit chemical kinetic, enzyme kinetic, or ligand-receptor binding data to a user-defined molecular mechanism represented symbolically by a set of chemical equations. Dynafit is available for Microsoft Windows XP or 2000.
Elementary Linear Algebra & Solutions to Elementary Linear Algebra
This book is an introduction to linear algebra, based on lectures given by me over 17 years, in the (now defunct) first year course MP103 at the University of Queensland.
Cosmic Survey: What are Your Ideas About the Universe?
Lesson plans and activity composed of a three-part questionnaire that launches students on discussions about where objects in space are located, and when they were formed- an introduction to the concepts of structure and evolution of the universe. This astronomical image-sorting activity lays the groundwork for discussions about the size, scale and history of the universe. Use it as a front-end assessment of how students understand the universe. Recommended for teachers of Grades 6-12 and inform
9.10 Cognitive Neuroscience (MIT)
This course explores the cognitive and neural processes that support attention, vision, language, motor control, navigation, and memory. It introduces basic neuroanatomy, functional imaging techniques, and behavioral measures of cognition, and discusses methods by which inferences about the brain bases of cognition are made. We consider evidence from patients with neurological diseases (Alzheimer's disease, Parkinson's disease, Huntington's disease, Balint's syndrome, amnesia, and focal lesions
