Professor Diamond builds on previously introduced material about the cardiac system and introduces angiology, the study of the blood vessels. To begin, she draws a diagram of the composition of the circulatory system, showing how the arteries, arterioles, capillaries differ from veins and veinules. She also explains what blood vessels are made of and their specific functions. She then details elastic arteries (those more limited in number...more

Jennifer Raymond (Stanford University) is building a "wiring diagram" for the brain. By bridging the gap between individual synapses and whole-brain learning & memory, Raymond's research offers new insights and strategies for medical rehabilitation and K-12 education.

It is important that chemists agree on notation and nomenclature in order to communicate molecular constitution and configuration. It is best when a diagram is as faithful as possible to the 3-dimensional shape of a molecule, but the conventional Fischer projection, which has been indispensable in understanding sugar configurations for over a century, involves highly distorted bonds. Ambiguity in diagrams or words has led to multibillion-d...more

In this lecture Processor Lewin introduces elasticity and Young's modulus. The fractional length deformation of a material (the strain) depends on the force per unit area (the stress). The stress vs. strain dependence is described conceptually, then explored empirically. The speed of sound in a material depends on the stiffness and density of the material; from this follows the fundamental frequency at which a rod resonates. Professor Lewi...more

Figuring out configurations for the d-block elements.

This lecture deals exclusively with frictional forces. Starting with a block at rest on a horizontal surface, Professor Lewin describes the normal force, the maximum frictional force that must be overcome to budge the block, and the coefficient of static friction. He continues to make measurements of the coefficient of static friction, and presents ways to reduce friction using hydroplanes and air tracks. Even a flea can move a very heavy...more

In this economics-oriented lecture, Professor Shapiro introduces neoclassical utilitarianism as it was formulated by economist Vilfredo Pareto and further described by Francis Edgeworth, examining such concepts as indifference curves, transitivity, the Pareto principle, and the Edgeworth box diagram. It is revealed that the main departure of neoclassical utilitarianism from classical utilitarianism was that it did away with Bentham's troub...more

Jeff Housenbold, CEO of Shutterfly, recalls how he learned that merging community with commerce was the winning ticket in business online. He recounts his days at Raging Bull, an upstart financial vehicle that knocked the larger, more established players out of the ring. It's secret? The site was bullish on building community and responsive to its users, resulting in millions of users in just a few short months. Furthermore, Housenbold cre...more
