question:  Peter Schattschneider is a cientist who has specialized knowledge in the exploration of the interactions of matter and energy across what?
answer: the physical universe
context: Title: Large Underground Xenon experiment
  Passage: The Large Underground Xenon experiment (LUX) aims to directly detect weakly interacting massive particle (WIMP) dark matter interactions with ordinary matter on Earth.  Despite the wealth of (gravitational) evidence supporting the existence of non-baryonic dark matter in the Universe, dark matter particles in our galaxy have never been directly detected in an experiment.  LUX utilizes a 370 kg liquid xenon detection mass in a time-projection chamber (TPC) to identify individual particle interactions, searching for faint dark matter interactions with unprecedented sensitivity.
  Title: Peter Schattschneider
  Passage: Peter Schattschneider (a.o. Univ.Prof.  Dipl.-Ing.  Mag.rer.nat.  Dr.techn.) (born 1950 in Vienna) is an Austrian Physicist and Science-Fiction-Writer, currently a Professor at the Institute of Solid State Physics and a staff member of the USTEM special unit of the Vienna University of Technology.  His research focuses on electron microscopy, specifically on Electron energy loss spectroscopy and the inelastic interactions between electrons and matter.  He is also interested in the history of physics, the science in Science Fiction, and the role of science in society.  His group was responsible for the discovery of Electron magnetic circular dichroism in 2006.
  Title: Biologist
  Passage: A biologist, is a scientist who has specialized knowledge in the field of biology, the scientific study of life.  Biologists involved in fundamental research attempt to explore and further explain the underlying mechanisms that govern the functioning of living matter.  Biologists involved in applied research attempt to develop or improve more specific processes and understanding, in fields such as medicine, industry and agriculture.
  Title: Pharmacist
  Passage: Pharmacists, also known as chemists (Commonwealth English) or druggists (North American and, archaically, Commonwealth English), are healthcare professionals who practice in pharmacy, the field of health sciences focusing on safe and effective medication use.  A pharmacist is a member of the health care team directly involved with patient care.  Pharmacists undergo university-level education to understand the biochemical mechanisms and actions of drugs, drug uses, therapeutic roles, side effects, potential drug interactions, and monitoring parameters.  This is mated to anatomy, physiology, and pathophysiology.  Pharmacists interpret and communicate this specialized knowledge to patients, physicians, and other health care providers.
  Title: Domain-specific learning
  Passage: Domain-specific learning theories of development hold that we have many independent, specialized knowledge structures, rather than one cohesive knowledge structure.  Thus, training in one domain may not impact another independent domain.
  Title: Technocracy
  Passage: Technocracy is a system of governance where decision-makers are selected on the basis of technological knowledge.  Scientists, engineers, technologists, or experts in any field, would compose the governing body, instead of elected representatives.  Leadership skills would be selected on the basis of specialized knowledge and performance, rather than parliamentary skills.  Technocracy in that sense of the word (an entire government run as a technical or engineering problem) is mostly hypothetical.  In another commonly used sense, technocracy is any portion of a bureaucracy that is run by technologists.
  Title: Physicist
  Passage: A physicist is a scientist who has specialized knowledge in the field of physics, the exploration of the interactions of matter and energy across the physical universe.
  Title: CNERU
  Passage: The "Cordoba Near Eastern Research Unit" (CNERU), is an interdepartmental and interdisciplinary unit of the Faculty of Humanities of the University of Córdoba (Spain), which offers undergraduate and graduate courses and seminars related to all areas of Near and Middle Eastern Studies and seeks to foster knowledge of Near and Middle Eastern societies from the ancient period to the modern times.  Through its academic activities CNERU also seeks to promote dialogue and understanding on the complexities of the modern Middle East.  CNERU assists with and enhances the dissemination of specialized knowledge of this field through publications and media diffusion in Spanish-speaking countries and abroad.  CNERU was founded in 2012 within the Faculty of Humanities of Cordoba University.
  Title: Business process modeling
  Passage: Business process modeling (BPM) in systems engineering is the activity of representing processes of an enterprise, so that the current process may be analysed or improved.  BPM is typically performed by business analysts, who provide expertise in the modeling discipline; by subject matter experts, who have specialized knowledge of the processes being modelled; or more commonly by a team comprising both.  Alternatively, the process model can be derived directly from events' logs using process mining tools.
  Title: AirPair
  Passage: AirPair is a service and eponymous company that connects people who need help with programming issues (usually, programmers at small technology companies or at finance companies that use technology products) and people who can help them.  Unlike services such as oDesk and Elance, AirPair is not a service for outsourcing programming tasks, but rather a service that facilitates one-off knowledge transfers from people with highly specialized knowledge of particular technology stacks or programming issues to people who are in need of specialized help.
