Professor Sylvia Ceyer explains the standard Gibbs free energy of formation and its relationship to thermodynamic stability. The Second Law of Thermodynamics is defined as it relates to controlling spontaneity with temperature. The lecture concludes by defining the thermodynamic equilibrium constant and the reaction quotient/direction of change in a chemical equilibrium.

According to Wirt, the biggest factor in determining whether a convergence device is successful or not is the rate of the technical change of its components.

Professor Blight begins his lecture with a description of the sea change in Civil War scholarship heralded by the Social History revolution of the 1960s and 1970s. Along with a focus on the experience of the common solider, women, and African Americans, a central component of this shift in scholarly emphasis was an increased interest in the effects of the war on the Union and Confederate home fronts. After suggesting some of the ways in wh...more

Inevitably, when a company goes public, there's an enormous amount of change that takes place, says Levinson. While the IPO may be an indication of financial success, the true measure is within the company, and maintaining a level of normalcy and maintaing the company's original culture, he adds.

Genetics controls evolution. There are four major genetic systems, which are combinations of sexual/asexual and haploid/diploid. In all genetic systems, adaptive genetic change tends to start out slow, accelerate in the middle, and occur slowly at the end. Asexual haploids can change the fastest, while sexual diploids usually change the slowest. Gene frequencies in large populations only change if the population undergoes selection.

Steve Jurvetson, Managing Director of Draper Fisher Jurvetson (DFJ), explains that VC firms are supposed to think first about maximizing investment return for investors--but they also have a perfect opportunity to change the world through entrepreneurs. When DFJ evaluates an opportunity, they look at whether it extends lives, makes a sustainable planet, provides better energy with renewables, and even narrows the rich/poor gap, he says.

Companies today need to be nimble and adaptable to the changing environment and market around them. Being nimble is important. The second skill is to think through when you're going to ship your product. If you think about the innovation; is it a 2x improvement, is it a 10x improvement? Think about what the market will be when you ship your product. If you have a four-year development cycle, youwill have a physical product that's going to ...more
