Adaptive Evolution is driven by natural selection. Natural selection is not "survival of the fittest," but rather "reproduction of the fittest." Evolution can occur at many different speeds based on the strength of the selection driving it. These types of selection can result in directional, stabilizing, and disruptive outcomes. They can be driven by frequency-dependent selection and sexual selection, in addition to more standard types of...more

Martin Eberhard discusses the shortfalls of using Solar Energy as a key component in manufacturing a car. He believes that using fuel-cells to drive cars is a huge stretch in imagination. He finally notes that a mix of plug-in hybrid and gasoline is a viable idea for an interim solution for alternative energy sources to drive a car.

In this lecture, Professor Kagan continues to discuss the constitution of Athens. In particular, he explores the judicial workings of Athens. He describes in detail the effort of the Athenians to create a system of justice that would not only minimize tampering, in order to insure justice, but also maximize citizen participation. After this discussion, Professor Kagan comments on the role of women in Athens by looking at two types of...more

Larry Bawden discusses the immense potential in Solar Energy by illustrating the high demand for this alternative source. He notes that there is huge demand from a variety of sources - residential houses to large industries. He also highlights the fact that substantial demand for this energy source is international.

This course is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. The course introduces the fundamentals of the lumped circuit abstraction. Topics covered include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; amplifiers; energy storage elements; dynamics of first-...more

Climate change will be a core concern that will influence policy and economic activity for years to come. It raises classic issues of distributional justice, law and science, risk, uncertainty and precaution, federalism, technology policy, and international relations. Students will leave this course with an understanding of the sources and impacts of climate change, the key state, national and international policies, and the role of law.

Understanding conformational relationships makes it easy to draw idealized chair structures for cyclohexane and to visualize axial-equatorial interconversion. After quantitative consideration of the conformational energies of ethane, propane, and butane, cyclohexane is used to illustrate the utility of molecular mechanics as an alternative to quantum mechanics for estimating such energies. To give useful accuracy this empirical scheme...more

Thompson stresses the need for customer diversity. Software companies that were dependent on Fortune 1000 companies for their business suffered when their niche clients also suffered in the economic downturn. If a company is to survive challenging economic times, companies must have a diverse customer base, he says. Symantec brings stability to its business by serving individual customers as well as the largest governments and...more

Armen Berjikly, Founder and CEO of Experience Project, discusses how to build a start-up team, a task that he argues is critical for success. Berjikly suggests building a team of people with complementary skills by reaching out through personal networks and in some cases recruiters. On the other hand, he suggests that entrepreneurs avoid hiring from sites such as Craigslist or other sources where it is difficult to verify someone's skills.
