In India heart attacks, diabetes and cancer are increasing within the wealthy and the poor. Martina Merten reports for the Pulitzer Center.

Assessment in Math and Science-When I Was in School...
Workshop 8. When I Was in School...: Implementing Assessment Reform (90 min.)
'Changing old ways is not easy. Communication is the first step toward encouraging support for new assessment strategies. This workshop will focus on the importance of collaboration among teachers, administrators, and especially parents, when implementing assessment reform in a school or district. Content Guide: K. Michael Hibbard.'
Roll-bonded aluminium alloy diffusion couple annealed for 60 minutes at 600°C.
This micrograph shows the grain structure of a roll-bonded aluminium alloy diffusion couple annealed for 60 minutes at 600°C. The upper half of the couple is Al-0.5Fe-1.0Mn (wt.%), the lower half is Al-1.0Si (wt.%). Annealing has recrystallised the microstructure. The Al-Fe-Mn alloy has many intermetallic particles (the dark phase). These help create recrystallisation nuclei, hence this alloy has a high density of small grains relative to the Al-Si alloy.The Barker's etch produces a thick oxide
On The Technical Features Of The Endoscope - OES Modelscope as a Case in Point
The Olympus Optical Company of Japan was formed in 1919, with the introduction of the first generation single lens reflects camera, and soon after with the first microscope. Since that time, the organisation has developed and is now split into three main divisions: manufacturing and supplying cameras, microscopes and endoscopes. Other smaller specialist divisions exist suppling such products as dictaphones. Perhaps, rather surprisingly, the endoscope division is the largest part of the organisat
An Interactive Shape Modeling System for Robust Design of Functional 3D Shapes
In Architecture, it is essential to design functional and topologically complicated 3D shapes (i.e. shapes with many holes, columns and handles). In this paper, we present a robust and interactive system for the design of functional and topologically complicated 3D shapes. Users of our system can easily change topology (i.e. they can create and delete holes and handles, connect and disconnect surfaces). Our system also provide smoothing operations (subdivision schemes) to create smooth surfaces.
Sports slide show
This video is a slide show listing several sports. You can read the name of the sport as you hear it and see the image. The sports are repeated twice.
Handwriting Lesson: Letter Size and Placement
Children have fun learning size and placement of tall, small, and descending letters with the letter sizes and places activity.
CMS.600 Videogame Theory and Analysis (MIT)
This course will serve as an introduction to the interdisciplinary academic study of videogames, examining their cultural, educational, and social functions in contemporary settings. By playing, analyzing, and reading and writing about videogames, we will examine debates surrounding how they function within socially situated contexts in order to better understand games' influence on and reflections of society. Readings will include contemporary videogame theory and the completion of a contempora
2.14 Analysis and Design of Feedback Control Systems (MIT)
This course develops the fundamentals of feedback control using linear transfer function system models. It covers analysis in time and frequency domains; design in the s-plane (root locus) and in the frequency domain (loop shaping); describing functions for stability of certain non-linear systems; extension to state variable systems and multivariable control with observers; discrete and digital hybrid systems and the use of z-plane design. Assignments include extended design case studies and cap
9.322J Genetic Neurobiology (MIT)
This course deals with the specific functions of neurons, the interactions of neurons in development, and the organization of neuronal ensembles to produce behavior. Topics covered include the analysis of mutations, and molecular analysis of the genes required for nervous system function. In particular, this course focuses on research work done with nematodes, fruit flies, mice, and humans.
Multiplying rational expressions is basically two simplifying problems put together. This video clip explains how to multiply rationals by factoring both numerators and denominators and identifying equivalents of one to cancel. Dividing rational expressions is the same as multiplying with one additional step—we take the reciprocal of the second fraction and change the division to multiplication. (1:41)
Information Pioneers: Sir Tim Berners-Lee
This six minute video explains how the world wide web came to be and the rules that were used to start it including everything being free to join. The connections are stressed as well as how the developer is still working on creating a more sophisticated web. A good review of why the web was created as well as how it came into being.
This video explains how a central angle is an angle where the vertex is on the center of the circle and the endpoints are on the circle. The endpoints on the circle are also the endpoints for the angle's intercepted arc. The angle measure of the central angle is congruent to the measure of the intercepted arc which is an important fact when finding missing arcs or central angles. (2:12)
This video describes how inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc. Inscribed angles that intercept the same arc are congruent. (1:44)
Angles in Semicircles
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees. This video describes how angles in a semicircle can be used to find missing missing angles and lengths. Pythagorean's theorem can be used to find missing lengths (remember that the diameter is the hypotenuse). Also, the measure of an angle formed by a chord to a tangent is half the intercepted arc. (2:08)

Lose Yourself in the Digits - Song
This music video is to the tune of Eminem's "Lose Yourself" and teaches about the concept of Pi. Lyrics are not included on the screen but can be found at www.teachpi.org. The lyrics in the chorus are, "You better lose yourself in the digits of pi. It's a high but you got a thousand more to go. The numbers do not stop or drop into pattern, no. To memorize it would take most of a lifetime." (04:26)
