Q1.00002: The Energy Problem: What Can Physicist Do? Invited Speaker: Among Americans most serious concerns are national security, which is intimately tied to our energy security, economic competitiveness, and the environment. These issues transcend our national boundaries and have serious implications for the entire world. At the core of these problems is the need to secure, clean, affordable and sustainable sources of energy. Progress must be made to decrease the demand of energy per person and the creation of new sources of clean, CO$_2$ neutral energy. After briefly describing the energy problem with emphasis on the latest findings on climate change, the remainder of the talk will describe our current options and some areas of energy research that may lead to transforming technologies.

Q1.00003: The String Theory Landscape Invited Speaker: In recent years, it has become increasingly clear that string theory, our most promising framework for a unified theory of the fundamental interactions, admits a ``landscape'' of vacua permitting different laws of 4d physics. That is, although the underlying theory is unique, it admits a large number of metastable solutions manifesting different effective cosmological constants, low-energy gauge groups and matter contents, and so forth. I describe the theoretical evidence in favor of this picture, the close connection to ideas in inflationary cosmology, and the scenarios for 4d physics (including testable ideas about inflation and particle physics) that have resulted from this research.
