According to Musk, some causes of the high costs in space exploration are: The energy to launch a rocket into space is very high, all the calculations have to be right and this is very expensive given the low launch rate. His final analysis is that rockets should be a lot cheaper and presently there are a lot of inefficiencies.

The visual system has developed to allow us to navigate in a complex and dangerous world in order to find food and to avoid danger. This survival system works by building a complex three-dimensional model based on two-dimensional data from the retina. This model is tested against "reality" and checked with information from other senses and updated if needed. The brain suppresses the complexity of this processing and we believe that visi...more

Although molecular mechanics is imperfect, it is useful for discussing molecular structure and energy in terms of standard covalent bonds. Analysis of the Cambridge Structural Database shows that predicting bond distances to within 1% required detailed categorization of bond types. Early attempts to predict heats of combustion in terms of composition proved adequate for physiology, but not for chemistry. Group- or bond-additivity schemes a...more

The Industrial Revolution in France is often said to have been entirely overshadowed by British industrial development. This analysis is inaccurate because it ignores the significance of domestic and other non-factory occupations. Indeed, it was the class of artisan workers, rather than industrial factory workers, who were first responsible for the organization of labor movements. One of the great innovations of the factory was the imposit...more

This lecture continues the analysis of the Capital Asset Pricing Model, building up to two key results. One, the Mutual Fund Theorem proved by Tobin, describes the optimal portfolios for agents in the economy. It turns out that every investor should try to maximize the Sharpe ratio of his portfolio, and this is achieved by a combination of money in the bank and money invested in the "market" basket of all existing assets. The market basket...more

Marxism is the second Enlightenment tradition upon which the course will focus. Contrary to popular belief, Marx did not hate capitalism but derived from economic analysis that it would self-destruct and lead to socialism. It is also a myth that Marx did not care about freedom; he was only egalitarian in the sense that he wanted everyone to have freedom. Ergo, Professor Shapiro asserts that Marx's dialectical materialism is as committed to...more

Young talks about how it is important to step back and understand your own weaknesses. This allowed him to improve his ball throwing skills, even though he had a height disadvantage from other quarterbacks. According to Young, a great negotiator is able to understand his strengths and weaknesses through self-analysis.

Note: This course is being offered this summer by Stanford as an online course for credit. It can be taken individually, or as part of a master’s degree or graduate certificate earned online through the Stanford Center for Professional Development. The goals for the course are to gain a facility with using the Fourier transform, both specific techniques and general principles, and learning to recognize when, why, and how it is used. To...more

Professor Kleiner traces the evolution of Roman architecture from its beginnings in the eight-century B.C. Iron Age through the late Republican period. The lecture features traditional Roman temple architecture as a synthesis of Etruscan and Greek temple types, early defensive wall building in Rome and environs, and a range of technologies and building practices that made this architecture possible. City planning in such early Roman coloni...more
