Turnaround: Third World lessons for First World growth [Audio]
Speaker(s): Peter Blair Henry | Thirty years ago, China seemed hopelessly mired in poverty, Mexico triggered the Third World Debt Crisis, and Brazil suffered under hyperinflation. Since then, these and other developing countries have turned themselves around, while First World nations, battered by crises, depend more than ever on sustained growth in emerging markets. In Turnaround, economist Peter Blair Henry argues that the secret to emerging countries’ success (and ours) is discipline—sust
20.109 Laboratory Fundamentals in Biological Engineering (MIT)
This course introduces experimental biochemical and molecular techniques from a quantitative engineering perspective. Rigorous quantitative data collection, statistical analysis, and conceptual understanding of instrumentation design and application form the underpinnings of this course. The four discovery based modules include DNA Engineering, Protein Engineering, Systems Engineering, and Biomaterials Engineering. Additional information is available on the course Wiki (hosted on OpenWetWare.) T
The Spiritual Exercises of St. Ignatius Loyola: Dynamics of the Spiritual Exercises
The essential dynamics of the Spiritual Exercises are discussed from the different perspectives of Fathers John O?Malley, George Aschenbrenner, John Padberg, and William Barry.
Detecting Down’s syndrome in the unborn fetus
Downs syndrome is the condition that is screened for the most in pregnant women because of the increased risk with the increasing age of mothers. This free course, Detecting Downs syndrome in the unborn fetus, describes several bioanalytical tests, and how these are used in conjunction with scans to screen and diagnose the condition.Author(s):
5.72 Statistical Mechanics (MIT)
This course discusses the principles and methods of statistical mechanics. Topics covered include classical and quantum statistics, grand ensembles, fluctuations, molecular distribution functions, other concepts in equilibrium statistical mechanics, and topics in thermodynamics and statistical mechanics of irreversible processes.
14.772 Development Economics: Macroeconomics (MIT)
This course emphasizes dynamic models of growth and development. Topics covered include: migration, modernization, and technological change; static and dynamic models of political economy; the dynamics of income distribution and institutional change; firm structure in developing countries; development, transparency, and functioning of financial markets; privatization; and, banks and credit market institutions in emerging markets. This course contributes to the fulfillment of requirements for the
How to Set up a Still Life in Oil Painting
This Expert Villiage video shows how one sets up a still life for oil painting. He focuses on how light effects the still life and how you can do anything with still life. (2:27)
What goes up must come down
Falling demand for oil is not just an immediate reaction to the current financial crisis but a response to the structural impact of five years of very high oil prices, says Dr Pierre Noel, an expert in energy economics and policy, who notes that oil prices will rise again due to the cyclical nature of the business. However, Dr Noel believes that OPEC exacerbates these ups and downs by overshooting in both directions and considers the long term implications as the OPEC cartel gathers strength.
Douglas Melton, Harvard University: "Stem Cell Challenges in Biology and Public Policy" - April 10,
Douglas Melton will discuss the biology and public policy challenges surrounding stem cell research. The potential of human embryonic stem cells for understanding human development and finding new therapies will be presented. Dr. Melton is a cell and molecular biologist as well as an advocate of embryonic stem cell research. His research focuses on the developmental biology of the pancreas. One of the primary goals of his work is to understand how human embryonic stem cells differentiate into pa
Virtual laboratories in Molecular and Cell Biology - Immuno-electron-microscopy
A virtual laboratory that includes immuno-gold labelling and transmission electron micrography (immuno-EM). It allows the student to study intracellular-traffic pathways of two cell-surface receptor molecules, following stimulation of the cells with their specific ligand, for different time periods. The programme first introduces the theory underlying the techniques and includes a video of EM work in a real laboratory. The student is then taken through a series of questions which requires them t
Virtual laboratories in Molecular and Cell Biology - SDS-PAGE
A protein analysis laboratory using SDS-PAGE, western-blotting and endoprotease digestion. The programme includes a section on the theory of the techniques, a video demonstration in a real laboratory, and a series of questions which guide the students through the structural analysis of model proteins (3 are included). Students go to the virtual laboratory and devise their own experiments in order to determine the molecular weight, subunit composition etc of the proteins. Results (gels and blots)
Molecular reaction dynamics
This package, written in 1998, includes interactive questions and demonstrations on the dynamics of chemical reactions. The aim is to show the effect of the potential energy surface, on reaction rates. It is intended for third or fourth year undergraduates in Chemistry.

Fracture surface in a liquid crystalline polymer, oriented by a magnetic field
Above their melting point, liquid crystalline polymers exhibit a mesophase within which, although able to flow and are not arranged in a crystal, they exhibit long range orientational order. This molecular alignment can be exploited to make high strength and stiffness fibres such as Kevlar, or even mouldable thermotropics such as Vectra. Molecular alignment can also be controlled by an external applied field; a property exploited in liquid crystal displays. This polymer has been subjected to a m
Injection-moulded polystyrene (PS) case
The colours in the image are the result of birefringence and relate to the residual strain in the polystyrene. The pattern of strain is indicative of the flow of material during the injection process and it highlights the injection point (known as a 'sprue') which can also be identified by a small lump on the surface; the molecular alignment is greatest near this point. Towards the edges of the ruler and along its length, the material becomes more relaxed and as the molecular alignment falls, th
Injection-moulded polypropylene (PP) hinge
The colours in the image are the result of birefringence and relate to the residual strain in the polypropylene. The pattern of strain is indicative of the flow of material during the injection process and reveals the molecular alignment in the constriction which constitutes a hinge. The aligned molecules provide a fatigue resistant, flexible joint. A sprue which has been cut off is also visible in the top left-hand corner of the image.
