This lecture covers resistive forces such as air drag. It includes the viscous (linear in velocity) and pressure (quadratic in velocity) terms. Quantitative demonstrations with balloons and with ball bearings dropped in syrup are shown. He concludes with numerical calculations of air drag examples, also discussing the contribution of air drag to the quantitative experiments down earlier in the course with falling apples.

The focus of the lecture is on fluid dynamics and statics. Different properties are discussed, such as density and pressure. The Archimedes' Principle is introduced and demonstrated through a number of problems. The final topic of the lecture is Bernoulli's Equation.

Professor Sylvia Ceyer continues her discussion on chemical equilibrium and external effects such as a change in volume, adding inert gas, and a change in temperature. Parameters are set for maximizing the yield of a reaction, and the Principle of Le Chatelier's is returned to. Hemoglobin is used as an example involved in a series of equilibrium reactions in response to oxygen pressure.

Sutton talks about several important factors that turn people into jerks. He describes how being around many aggressive people will transform a person into a jerk. He also explains how pressure is a key contributor in building jerk behavior.

Ringold informs us that drugs for lowering blood pressure and those to lower cholesterol are among the leading pharmaceutical products today--and these are not treating a disease. The fundamental opportunity lies in the surrogate market, he says.

Early Modern England: Politics, Religion, and Society under the Tudors and Stuarts (HIST 251)Professor Wrightson reviews the consequences of the economic and population changes discussed in the last lecture. While economic shifts allowed some members of English society, especially members of the gentry and the land-holding classes, to increase their wealth, they also (coupled with an expanding population and price inflation) resulted in th...more
