William Sahlman, professor at Harvard Business School, talks about the four key elements of an entrepreneurial venture: 1) People, 2) Opportunity, 3) Context and 4) Deal. He illustrates with the example of John Osher who developed the spin toothbrush.

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.

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.

February 25, 2009 lecture by Jacques Bouchard for the Woods Energy Seminar (ENERGY301). In his talk "Can Nuclear Energy be a Sustainable Contribution to Address Climate Change Concerns? The French Experience," Jacques Bouchard gives a comprehensive overview of France's development and innovation of nuclear energy technology.

Steve Young, former quarterback of the San Francisco 49ers, explains how he uses different elements of negotiation throughout his life, whether it is in his marriage or on the field. According to Young, financial returns are not the only incentive in negotiations. He describes one of the negotiation tactics he used with his agent Leigh Steinberg.

Professor Barry Sharpless of Scripps describes the Nobel-prizewinning development of titanium-based catalysts for stereoselective oxidation, the mechanism of their reactions, and their use in preparing esomeprazole. Conformational energy of cyclic alkanes illustrates the use of molecular mechanics.

The Big Bang created the physical universe. Of course life is part of this physical universe, but the immediate building blocks of life are chemicals. Before the Big Bang, words such as “time” had no meaning, but even in the first few minutes there could be no chemistry since there were no atoms. The nuclei of some of the lighter elements formed within minutes, atoms some time later, and elements heavier than lithium were forged in the sup...more

After a discussion of electrochemical cells, Professor Sylvia Ceyer defines the points of oxidation and reduction in a battery as the anode and cathode, respectively. She discusses the application of Faraday's Law and its relationship to electrochemical cells. Finally, the relationship between cell potential and Gibbs free energy is highlighted.

Professor Sylvia Ceyer devotes this lecture to a discussion of the periodic table, beginning with its history. Period trends are covered, including ionization energy, electron affinity, elecrtonegativity, and atomic sizes. The lecture concludes with isoelectronicity, where two molecular entities have the same number of valence electrons and the same structure, regardless of the nature of the elements involved.
