17.874 Quantitative Research Methods: Multivariate (MIT)
This course is the second semester in the statistics sequence for political science and public policy offered in the Political Science Department at MIT. The intellectual thrust of the course is a presentation of statistical models for estimating causal effects of variables. The model of an effect is a conditional mean (though we might imagine other effect). The notion of causality is the effect of one variable on another holding all else constant.
Cold War: Red China - part 1/5
1949 - 1972 Chinese communists win the longest civil war in 20th century history. Mao's land reforms are popular but in 1958, he embarks on a series of catastrophic changes. China maintains an incrasingly uneasy relationship with the Soviet Union. In 1960, the Sino-Soviet split paves the way for President Nixon's historic visit to Beijing.
Statistics - an intuitive introduction : normal distribution
One of the most common statistical distributions is the normal distribution. What does it tell us and how do we use it?

Virtual Maths, Cylinder Voids - Calculating volume
Interactive simulation with exercises and video demonstrating the use of auger piling and showing how to calculate the volume of cocrete needed to fill the cylindrical voids.
The PDZ Domain as a Complex Adaptive System
Specific protein associations define the wiring of protein interaction networks and thus control the organization and functioning of the cell as a whole. Peptide recognition by PDZ and other protein interaction domains represents one of the best-studied classes of specific protein associations. However, a mechanistic understanding of the relationship between selectivity and promiscuity commonly observed in the interactions mediated by peptide recognition modules as well as its functional meaning
2.4 Defining terms
Care is needed at all stages of life. This unit makes care in the family its focus because the overwhelming majority of care, including health care, is supplied in families, much of it in private, much of it unnoticed and unremarked upon. The meaning of the term (informal carer) and the word (care) itself are explored.
