Saving the World: Reflections on the US Government and Energy Security

“Saving the world” must sound terribly overstated, but global warming has become just that kind of issue for the U.S. government. Countering the effects of global warming has become an integral part of nearly every U.S. policy, and it is clear that if the U.S. government is to save our country from the effects of global warming, it must literally save the world, as we all live in a shared environment. Also, the need to save the world is mostly an issue of our own making, reflecting our desire for better, more secure lives based on improved health, agriculture, technology, national defense and mobility, and we have been so successful at creating these lives that much of the world now aspires to live the same. These improvements, however, require ever higher energy demands, which have been largely met by fossil fuels like coal, oil and gas that generate the greenhouse gases which have primarily fueled global warming.

Through accidents of geology and creative U.S. technology, our country is now offering the world an alternative to high-carbon fuels like coal and oil, and that is shale gas, natural gas produced from organic-rich shales that abound in our country and in much of the world — even in Kentucky! These rocks have been known and ignored for a long time, because the technology to fracture them and allow gas to flow was available until recently. This technology has now made gas the “go-to” fuel to counter global warming, because it produces less than half the CO2 of burning coal and lacks the associated particulate and gaseous pollutants. As a result, it has become U.S. government policy to help wean countries from coal dependence, diversify energy sources, and encourage the switch to natural gas and other unconventional fuels.

Energy necessarily creates vulnerabilities and leverage among countries. Shale gas, for example, has made the U.S. a largely self-reliant, energy superpower and given it the leverage to further its environmental, energy-security and economic objectives, as well as those of its allies. At the same time, however, we must realize that gas is only a bridge fuel — a transition to a period of diverse, renewable energy, energy efficiency and sustainable development. It is hoped that this transition, what the Germans call “energiewende,” could ultimately result in a reorientation from demand to supply, a shift for centralized to dispersed energy distribution, and an overall democratization of energy.

Gas shales have clearly been a real game changer for the U.S., and potentially for the world, and for the last nine months as a Jefferson Fellow, I have been using my knowledge of gas shales to help colleagues in the Bureau of Energy Resources, Department of State, understand and assess shale resources. This has given me the opportunity to see how government works (or doesn’t) and how energy policy is formulated. In this talk, I would like to share some reflections on these issues with you.

Quantum mechanics and the geometry of spacetime

 

Abstract: Quantum mechanics is important for determining the geometry of spacetime. We will review the role of quantum fluctuations that determine the large scale structure of the universe. In some model universes we can give an alternative description of the physics in terms of a theory of particles that lives on its boundary. This implies that the geometry is an emergent property. Furthermore, entanglement plays a crucial role in the emergence of geometry. Large amounts of entanglement are conjectured to give rise to geometric connections, or wormholes, between distant and non-interacting systems.

About the speaker: Juan Maldacena is the leading string theorist of his generation. His 1998 discovery of the AdS/CFT correspondence set off a revolution in string theory, and has found applications in many areas of physics and mathematics. Maldacena's work since then has included groundbreaking work in particle physics, cosmology, and quantum gravity. He was awarded a MacArthur Fellowship in 1999, the 2007 APS Dannie Heineman Prize, the 2008 Dirac Medal, the 2012 Fundamental Physics Prize, and is a member of the National Academy of Sciences.

 

About the van Winter Memorial Lecture in Mathematical Physics

The van Winter Memorial Lecture honors the memory of Clasine van Winter, who held a professorship in the Department of Mathematics and the Department of Physics and Astronomy from 1968 to her retirement in 1999. Professor Van Winter specialized in the study of multiparticle quantum systems; her contributions include the Weinberg-van Winter equations for a multiparticle quantum system, derived independently by Professor van Winter and Professor Steven Weinberg, and the so-called HVZ Theorem which characterizes the essential spectrum of multiparticle quantum systems. She died in October of 2000.

Stargazing at MacAdam Observatory with Tim Knauer

The University of Kentucky's own MacAdam Observatory provides students with the opportunity to use the most powerful telescopic lenses on campus and see the universe. On clear nights, students are welcome to join director Tim Knauer and his graduate assistants as they look out into the stars and observe those celestial bodies.

Here, Tim and assistants Kyle and Aaron join us to talk about running the observatory and their experiences there.

Anthro Colloquium: Dr. William Y. Adams, "The Boasians"

Professor Emeritus, U Kentucky. He is the winner of the 1978 Herskovits Prize for his history of Nubia, Nubia: Corridor to Africa. In 2005 Adams was awarded the Order of the Two Niles, Sudan's highest civilian honor, for his contributions to Nubian history. Adams's work in Nubia began in 1959 as part of the UNESCO archaeological salvage campaign to excavate sites threatened by the rising flood waters of Lake Nasser following the construction of the Aswan Dam.
