Dell describes the PC industry today as a jump ball environment where no company can stay in a strong position for long. The development of wireless networks, miniaturization, and the influence of the internet has changed the competitive landscape of the industry, he says. One of the biggest threats is the changing computing model. To combat this threat, Dell, Inc. is focused on online servers and storage, new online devices, and anticipat...more

William Sahlman, professor at Harvard Business School, highlights for critical elements to observe in the process of hiring people: 1) Integrity, 2) References, 3) Attitude and 4) Adaptability. He highlights the importance of seeing through a resume to the core of the person underneath, one way of which is to use your network of contacts to get the back story on an individual.

The lecture opens with tricks ("Z-effective" and "Self Consistent Field") that allow one to correct approximately for the error in using orbitals that is due to electron repulsion. This error is hidden by naming it "correlation energy." Professor McBride introduces molecules by modifying J.J. Thomson's Plum-Pudding model of the atom to rationalize the form of molecular orbitals. There is a close analogy in form between the molecular orbita...more

After discussing the classic determination of the heat of atomization of graphite by Chupka and Inghram, the values of bond dissociation energies, and the utility of average bond energies, the lecture focuses on understanding equilibrium and rate processes through statistical mechanics. The Boltzmann factor favors minimal energy in order to provide the largest number of different arrangements of "bits" of energy. The slippery concept of di...more

After a mock trial session to whittle down the most critical causes from an applicant pool of 10,000, Google.org chose just five areas of concentration: renewable energy, plug-in vehicles, prevention of pandemics, famines, and floods, public services for the poor, and job creation. And the organization's Executive Director, Larry Brilliant, offers this overview of these pressing global issues, and pinpoints Google's resources dedicated tow...more

Larry Bawden discusses the competitive strategy in solar energy start-ups lies in bringing vertical integration to your product mix. He believes that there is a huge potential for any viable technology in the value chain. He notes that continuous improvement of technology is key to the success of a company in this field.
