This lecture is an introduction to kinematics which ultimately leads (in Lecture 4) to trajectories in three-dimensions. Professor Lewin begins with a description of one-dimensional motion of a particle. He talks about average velocity, the importance of + and - signs, and our free choice of origin. He moves into a conversation about average speed vs. average velocity, instantaneous velocity (reviewing when velocity is zero,...more

Estrin emphasizes that a good leader and entrepreneur should have flexibility--flexibility in dealing with people and navigating through changes in plans. Estrin thinks that this is a hard time and environment for startups, but that should not prevent people from being entrepreneurs. Big companies must embrace entrepreneurial thinking.

February 11, 2009 lecture by Jefferson Tester for the Woods Energy Seminar (ENERGY301). In his talk "A Pathway for Widespread Utilization of Geothermal Energy--the Roles of Multi-scale Resource and Technology Research and Systems Analysis," Tester talks about the benefits and challenges of harnessing geothermal energy, and he asserts that it is a large resource that complements solar and wind energy and is both carbon free and scalable.

Earl talks about how the majority of the products at EA are sequels that are released every year. The main decision for EA on these projects is budgeting how many people to work on each every year, he says. Occasionally, there is a new product idea. This idea must pass a lot of market opportunity analysis before it is launched because it is very expensive and risky to build a new product. Still, new products are seen as a critical part...more
