After discussing the statistical basis of the law of mass action, the lecture turns to developing a framework for understanding reaction rates. A potential energy surface that associates energy with polyatomic geometry can be realized physically for a linear, triatomic system, but it is more practical to use collective energies for starting material, transition state, and product, together with Eyring theory, to predict rates. Free-radical...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

April 27, 2009 - Leonard Susskind discusses the basic physics of the diatomic molecule and why you don't have to worry about its structure at low temperature. Susskind later explores a black hole thermodynamics.
-
April 20, 2009 - Leonard Susskind explains how to calculate and define pressure, explores the formulas some of applications of Helm-Holtz free energy, and discusses the importance of the partition function.
-
May 11, 2009 - Leonard Susskind lectures on harmonic oscillators, quantum states, boxes of radiation and all associated computations such as wavelengths, volume, energy and temperature.
-
May 4, 2009 - Leonard Susskind explains the second law of thermodynamics, illustrates chaos, and discusses how the volume of phase space grows.

Wirt explains that the invention of the electric motor revolutionized the way factories operate. With steam power, there was one central boiler which dictated how the factory had to be organized. As electric motors evolved, it became possible to make small motors that could be distributed around the plant to provide power to individual machines allowing for greater flexibility. Now, electric motors are everywhere, he says....more

William Sahlman, professor at Harvard Business School, reflects on three things that helped John Osher, the developer of the low-cost spin toothbrush, succeed. Sahlman identifies three factors: 1) Reflecting on your experience to improve your understanding, 2) Looking at the situation differently to successfully innovate, and 3) Scanning your environment to find new opportunities.

Priceline co-founder Jesse Fink explains to entrepreneur Steve Blank how his early company was a technology-enhanced solution to a business model - and not a real technology play - that succeeded in providing for both business and consumer. Fink brings these same solutions to his current investment firm, MissionPoint, who believes it will be business models and capital markets that find environmental solutions, and not the technology itself.

Musk talks about the problems with space exploration in the US in the 22nd century. The long term plans are to have something cheaper and safer. In Russia, it is safer and cheaper and they have a better track record. They are constrained however by the weakness of the Russian economy. China is expected to launch their first person into space this month, becoming the third country to put a person into the orbit. They have great ambitions an...more

Anand Chandrasekaran, Producer of Tapestries of Hope, tells the tale of a small soap maker who realized that the gum they were giving away as a promotional item began to outshine their core product. The company had to make a bold decision to focus on what's selling, rather than what they deemed their core competency, and the rest is entrepreneurial history. Chandrasekaran's lesson is that we should keep ourselves receptive to new ideas and...more

During its inception, Dell explains how the computer industry was run by engineers. Over a thirty-year period however, customers began to have an important role in the industry, but many companies were still being run by engineers working to promote complexity. With complicated products being sold, says Dell, customers had to rent specialized software and hire consultants from the computer companies to get their products to work. As a resu...more
