Designing Digital Institutions: Science in Government 2.0
Beth Noveck - New York Law School
The current paradigm for decision-making is government is beset by instances of ideological bias and manipulation. The Bush-Cheney Administration, which imposed ideological litmus testing on scientific advisors, eliminated advisory panels, and selectively edited reports on environmental hazards and…
Astrophysics and Cosmology through Problems - 2A
Mark Wyman - PDT Partners LLC , Niayesh Afshordi - University of Waterloo
This course is aimed at advanced undergraduate and beginning graduate students, and is inspired by a book by the same title, written by Padmanabhan. Each session consists of solving one or two pre-determined problems, which is done by a randomly picked student. While the problems introduce various…

Volodya Miransky - Western University
Quantum Field Theory I course taught by Volodya Miransky of the University of Western Ontario
Science as an ethical community
Lee Smolin - Perimeter Institute for Theoretical Physics
I develop the idea that science works because scientists form communities defined by a set of ethical principles which, even if imperfectly applied, tend to lead to progress in our understanding of nature. While these communities have long been international, the combination of the internet with…
Toil, Trouble, and the Cold War Bubble: Physics and the Academy since World War II.
David Kaiser - Massachusetts Institute of Technology (MIT)
In the wake of recent swings in the values of technology stocks and the prices of real estate, many people have become (painfully) familiar with the boom-and-bust cycles of speculative bubbles. Although playing out on longer time-scales, student enrollments in the sciences have followed a remarkably…

Does electronic communication make any difference to the nature of expertise?
Harry Collins - Cardiff University
I introduce `The Periodic Table of Expertises\' (Collins and Evans 2007). The classification is driven by the idea of tacit knowledge. Its most important division is between the expertise of those who have acquired tacit knowledge pertaining to a specialism as a result of social interaction with the…
Mendeley: A Last.fm for Research? (IT tools for Science)
Victor Henning - Mendeley (United Kingdom)
Mendeley is a new \'science 2.0\' tool for managing & sharing academic papers. Its co-founder, Victor Henning, will highlight conceptual similarities between Last.fm and Mendeley to explore whether the ideas behind social music services can be applied to social software for researchers.
Physics Wiki (IT tools for Science)
Garrett Lisi - Pacific Science Institute
A wiki is an excellent tool for organizing and representing human knowledge. By building a personal wiki notebook, a scientific researcher may optimally organize past and current research notes. In this brief practical introduction I will provide a guided tour of an open scientific notebook --…
The Wiki: An Environment for Scholarly Conversation and Publishing (IT tools for Science)
Gerry McKiernan - Iowa State University
\'The Medium Is The Message ... The Audience Is The Content\', Marshall McLuhan, Understanding Media: The Extensions of Man, New York: McGraw-Hill, 1964. A \'wiki is a ... collaborative space ... because of its total freedom, ease of access, and use, [and] simple and uniform navigational conventions…
The evolution of scholarly communication and the supreme power of inertia
Andrew Odlyzko - University of Minnesota
The rapid technological change around us supports the idea of general speedup in the tempo of life, the illusion that we are living \'on Internet time.\' Yet many changes are still taking generations, and that includes changes in scientific communication as well as in sociology of science. The…
Averaging Robertson-Walker Cosmologies
Iain Brown - University of Oslo
The so-called cosmological backreaction arises when one directly averages the Einstein equations to recover cosmology. While usually applied to avoid employing dark energy models, strictly speaking any cosmological model should be built from such an averaging procedure rather than an assumed…
