We know about Dark Matter from gravitational interactions, but the nature of Dark Matter is still not understood. One of the possible models is that Dark Matter is made of Mirror Matter. How might this affect some measurable properties of the matter, e.g. lifetime of the neutron?

We depend on a number of natural resources to maintain our modern civilization; are we running out of some of these, do particular countries (with government subsidies) control some critical resources; are there some critical resources that we in the US are not producing that could be? Topics to be considered are: Introduction to basic controls of resource distribution; critical resources for civilization; rare earth elements and who has the most; fuels—are we running out?; alternative energy resources; and field trip introduction.

This course introduces the concepts of quantum mechanics by following the history of its development. The emphasis is on the physics, but there is some mathematics (kept to the barest minimum). The topics covered are the following: blackbody radiation; the photoelectric effect; the specific heat of solids; quantization of the atom; wave mechanics; the oscillator according to wave mechanics; the Pauli exclusion principle; the statistical interpretation of the wave function; the Heisenberg uncertainly principle; the debate over hidden variables; Bell’s theorem; how Bell’s theorem is used. A STEM background will be useful.

Eight sessions: Thursdays, 11:00 a.m. - 12:10 p.m., February 18, 25; March 3, 10, 17, 24, 31; April 7
ORICL lost one of its most popular teachers last year with the untimely death of Tina Riedinger. Her wonderful lectures on various topics in modern physics and cosmology were always informative, stimulating, and fully subscribed. This series of four lectures on renewable energy sources will be offered by Tina’s husband and other selected speakers.
Generation of electricity from wind and solar is increasing in the U.S. and in the world for a variety of reasons - governmental mandates, economic opportunities, concern about carbon emissions, etc. Some states (e.g., California) and some nations (e.g., Germany) have been especially aggressive in promoting renewable energy. The purpose of this course is to look carefully at the status of wind and solar in the world - understand what is the current status, discuss future opportunities, and realize both the opportunities and the constraints. In a series of four lectures, one will be spent on solar energy, one on wind, a third on storage issues, and a fourth on policies and projections.
Lee Riedinger led a program of experimental studies of nuclear structure at the Holifield Heavy Ion Research Facility at ORNL for many years. He was Chairman of the Physics Department, served on the staff of Senator Howard Baker, and held numerous senior administrative positions at UT. From 2000-2004, he was the ORNL Deputy Director for Science and Technology.
Four sessions: Wednesdays, 4:00 – 5:10 p.m., February 3, 10, 17, 24
ITER is the crown jewel of the international fusion power program using magnetically confined plasma. It has been two decades since the major milestone in fusion research of ‘breakeven’ was achieved on the Toroidal Fusion Test Reactor (TFTR) facility in the US and Joint European Tours (JET) in Europe. ITER has the goal of exceeding JET and TFTR by an order of magnitude and is expected to produce ten times as much fusion power as the input power required to create it. ITER is a technically difficult and complex project supported by a seven-party international collaboration, and is being designed and built by a new organization at the Cadarache Facility in southern France. The challenges of the project will be discussed from four different perspectives: the U.S. ITER Project Office, the Department of Energy, the ITER Organization, and the ORNL Fusion Program. The course will conclude with a discussion of the International Space Station (ISS). Like ITER, the ISS is a large and complex international project.
Brad Nelson is Chief Engineer for the U.S. ITER Project Office and leads the engineering effort. He joined the U.S. ITER effort with over 30 years experience at ORNL in the design and construction of fusion projects. The project included facilities at Oak Ridge as well as collaborations with other laboratories. Nelson is a registered professional engineer, received bachelors and masters degrees in mechanical engineering from the University of Missouri.
John Glowienka received his degrees from Rensselaer Polytechnic Institute. After a stint in the Air Force, his 30-year career at ORNL includes work in fusion using ion beams to measure plasma parameters and work in ORNL management. There he led laboratory activities dealing with safety, performance management, and performance assessment. After 30 years, he retired from ORNL to become the DOE program manager for ITER in Washington, DC. He has now retired from DOE and returned to live in Oak Ridge.
Wayne Houlberg received his degrees from the University of Wisconsin, Madison. He then joined the ORNL Fusion Energy Division where he developed theoretical models and computer simulations of fusion plasmas. These models played a key role in understanding the behavior of existing devices and assessing the performance of future devices. After retiring from ORNL in 2007, he joined the ITER Organization, living in Aix -en-Provence near the French Cadarache facility. At Cadarache, he worked in the ITER Integrated Modelling Section. After retiring (again) Wayne is now living in Oak Ridge.
Larry Baylor received degrees from Iowa State University and the University of Tennessee. He started his career at ORNL working on instrumentation design and development. He then moved to work on using high velocity solid hydrogen pellets to fuel fusion plasmas and currently leads pellet system design activities for the U.S. ITER Project Office.
Mark Uhran formerly directed the International Space Station effort in NASA's Office of Space Operations and is now Director for Strategic Communications for the U.S. ITER Project Office in Oak Ridge.

This course will start with some discussion of the discovery of stainless steel and detail its evolution, after overcoming some initial technical challenges, into a myriad of beneficial applications for industry, home, and art. One topic will be clarifying why stainless steel “rusts” at times that contradicts its “stainless” name.
Gerard M. Ludtka is a Distinguished Research Staff Member of the Processing and Joining Group of the Materials Science and Technology Division at the Oak Ridge National Laboratory with over 30 years of industrial and national laboratory research experience in metallurgy and materials science.
