1. A special event to mark the publication of Professor Barrow's new book, 'The Book of Universes'.
    This is a book about universes, a story that revolves around a single unusual and unappreciated fact: that Einstein?s famous theory of relativity describe universes ? entire universes. Not many solutions of Einstein's tantalizing universe equations have ever been found, but those that have are all very remarkable. Some of them describe universes that expand in size, while others contract; some rotate like a top and others are chaotic. Some are perfectly smooth, while others are lumpy, or shaken in different directions by tides of energy; some oscillate forever, some become lifeless and cold, while others head towards a runaway future of ever-increasing expansion. Some permit time travel into the past, and others allow infinitely many things to happen in a finite amount of time. Only a few allow life to evolve within them; the rest remain unknowable to conscious minds. Some end with a bang, some with a whimper. Some don?t end at all. Our story will encounter universes where the laws of physics can change from time to time and from one region to another, universes that have extra hidden dimensions of space and time, universes that are eternal, universes that live inside black holes, universes that end without warning, colliding universes, inflationary universes, and universes that come into being from something else ? or from nothing at all. Gradually, we will find ourselves introducing the latest and the best descriptions of the Universe we see around us today, together with the concept of the 'Multiverse' ? the universe of all possible universes ? that modern theories of physics lead us to contemplate. These are the most fantastic and far-reaching speculations in the whole of science. Other cosmology and astronomy books focus on particular topics ? dark matter, dark energy, the beginning of the universe, inflation, life-supporting coincidences, or the end of the universe ? but this book introduces the reader to whole universes in a coherent and unified way.

  2. Science for the Public, September 11, 2012. Steven Nahn, Associate Professor of Physics, Massachusetts Institute of Technology.
    Finding the Higgs —or Higgs-ish— is one of the greatest triumphs in the history of science. This particle is the source of mass that makes possible the existence of our familiar form of matter. Professor Steven Nahn explains what the Higgs boson is and why it is so important for a model of the structure of matter. He also describes the enormous challenge of finding the Higgs —even with the power of the Large Hadron Collider— and the extreme requirements of scientific verification for this elusive particle.
    Dr. Nahn is involved in one of the major projects at the LHC, the Compact Muon Solenoid.

  3. A new version of this talk, along with pictures, can be found here: dancingphysicist.com/quantum-physics-harry-potter/

    The universe of Harry Potter is filled with magic and wonder. Yet it is not that different from the world we inhabit. Just beneath the surface of our ordinary lives lies a shocking quantum reality. This talk is an introduction to some of the cutting edge research being carried out in quantum physics today, and how it relates to JK Rowling's universe of Harry Potter.

    Featuring physicist Krister Shalm and special guest magician Dan Trommater (dantrommater.com), this talk took place at the Department of Physics at the University of Toronto on February 26, 2010.

  4. Special Presentation “The Arrow of Time and the Evolution of the Universe” in the H.F. Deluca Forum -- open to the public. Co-organized by WID Town Center and MathBio4

    Speaker: SEAN M. CARROLL, Physicist, California Institute of Technology

    Moderated by: PATTY LOEW , Professor, Life Sciences Communication, College of Agricultural & Life Sciences, UW

    This talk, open to the public and MathBio4 attendees, is geared to captivate a broad audience. It will provide an intriguing perspective on the scale and evolution of the universe in terms those outside the field of physics will grasp and appreciate.

    The arrow of time is a central aspect of the physical world, from physics to biology. Dr. Carroll will discuss how it arises from the notion of entropy, how entropy is connected to cosmology and the Big Bang, and how the evolution of complexity relates to the evolution of entropy. A skilled moderator will guide questions after the talk to facilitate interactive dialogue with Dr. Carroll.

    Sean Carroll’s research focuses on theoretical physics and cosmology, especially the origin and constituents of the universe. He has contributed to models of interactions between dark matter, dark energy, and ordinary matter; alternative theories of gravity; and violations of fundamental symmetries. Carroll is the author of "From Eternity to Here: The Quest for the Ultimate Theory of Time," "Spacetime and Geometry: An Introduction to General Relativity," and the forthcoming "The Particle at the End of the Universe." He has been awarded fellowships by the Sloan Foundation, Packard Foundation, and the American Physical Society. His blog Cosmic Variance is hosted by Discover magazine.
