Matrix Concepts -- Multiplying Matrices
This module covers multiplication of matrices.
Do gamblers make good leaders?
A professor of corporate strategy at Tsinghua University explores the link between risk-taking in the casino and in the board room.
Visualizing Magnetic Field Lines
In this activity, students take the age old concept of etch-a-sketch a step further. Using iron filings, students begin visualizing magnetic field lines. To do so, students use a compass to read the direction of the magnet's magnetic field. Then, students observe the behavior of iron filings near that magnet as they rotate the filings about the magnet. Finally, students study the behavior of iron filings suspended in mineral oil which displays the magnetic field in three dimensions.

Why Study Icons with Dr Mary Cunningham
Icons -- religious images from the eastern Churches -- are far more than religious images as seen in western churches: they enable an encounter between the observer and the mystery. In this video, Mary Cunningham, an expert on Orthodoxy, introduces them.
Race activists want more black models
June 20 - Black rights campaigners in Brazil criticize labels at Sao Paulo Fashion Week for casting a small number of dark-skinned models and demand 20 percent quotas for future shows. Tara Cleary reports.
5.111 Principles of Chemical Science (MIT)
This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. In an effort to illuminate connections between chemistry and biology, a list of the biology-, medicine-, and MIT research-related examples used in 5.111 is provided in Biology-Related Examples.

6.641 Electromagnetic Fields, Forces, and Motion (MIT)
6.641 examines electric and magnetic quasistatic forms of Maxwell's equations applied to dielectric, conduction, and magnetization boundary value problems. Topics covered include: electromagnetic forces, force densities, and stress tensors, including magnetization and polarization; thermodynamics of electromagnetic fields, equations of motion, and energy conservation; applications to synchronous, induction, and commutator machines; sensors and transducers; microelectromechanical systems; propaga
16.050 Thermal Energy (MIT)
This course is taught in four main parts. The first is a review of fundamental thermodynamic concepts (e.g. energy exchange in propulsion and power processes), and is followed by the second law (e.g. reversibility and irreversibility, lost work). Next are applications of thermodynamics to engineering systems (e.g. propulsion and power cycles, thermo chemistry), and the course concludes with fundamentals of heat transfer (e.g. heat exchange in aerospace devices).
Statistics - an intuitive introduction : standard deviation

9.520 Statistical Learning Theory and Applications (MIT)
Focuses on the problem of supervised learning from the perspective of modern statistical learning theory starting with the theory of multivariate function approximation from sparse data. Develops basic tools such as Regularization including Support Vector Machines for regression and classification. Derives generalization bounds using both stability and VC theory. Discusses topics such as boosting and feature selection. Examines applications in several areas: computer vision, computer graphics, t
Hydrophone spatial averaging corrections from 1 to 100 MHz
The purpose of this work was to develop and experimentally verify a set of robust and readily applicable spatial averaging models to account for ultrasonic hydrophone probe's finite aperture in acoustic field measurements in the frequency range 1 - 100 MHz. Electronically and mechanically focused acoustic sources of different geometries were considered. The geometrics included single element circular sources and rectangular shape tranducers that were representative of ultrasound imaging arrays u
17.872 Quantitative Research in Political Science and Public Policy (MIT)
This course provides students with a rigorous introduction to Statistics for Political Science. Topics include basic mathematical tools used in social science modeling and statistics, probability theory, theory of estimation and inference, and statistical methods, especially differences of means and regression. The course is often taken by students outside of political science, especially those in business, urban studies, and various fields of public policy, such as public health. Examples draw
