The Discovery of our (Space-)Time

Wednesday March 6, 2013
1:00-2:00pm
Smith Seminar Room
PRB 1080

CCAPP Public Lecture - Free and open to all

The Large Hadron Collider, perhaps the greatest machine ever built by human beings, represents one step in a thousands-year-old quest to understand the nature of reality. A chapter in this adventure was closed with the much anticipated discovery of the Higgs Boson last summer. Its identification, and the measurement of its mass, has given us the first hint of what might be coming next. The favored idea, supersymmetry, would be the first extension of Einstein's space-time symmetry in 100 years. Will this be the generation to discover it, or is the information beyond our grasp?

David Kaplan is a professor of physics at Johns Hopkins University and producer of the upcoming documentary film Particle Fever.

Note: Documentary film crews will be present to record the talk and audience reactions.

The Particle at the End of the Universe:
How the Hunt for the Higgs Boson Leads Us to the Edge of a New World

Wednesday February 20, 2013
8:00pm
Smith Labs Room 1153 - Directions and Parking Info

CCAPP Public Lecture - Free and open to all

For decades, particle physicists have searched for the elusive Higgs boson, the missing piece to the "Standard Model" that explains the world we see. In July 2012, scientists at the Large Hadron Collider in Geneva announced that they found it. I will explain why the Higgs boson is so important, talk about the enormous challenge physicists overcame to build the LHC and get it running, and consider what the future of particle physics will look like.

The Era of International Space Station Research:
Discoveries and Potential of an Unprecedented Laboratory in Space

Date: Monday April 4, 2011
Time: 7:30pm
Location: Smith Labs 1153
Speaker: Julie A. Robinson, Ph.D. --
(International Space Station Program Scientist, NASA Johnson Space Center, Houston, TX)

The assembly of the International Space Station was completed in early 2011. Its largest research instrument, the Alpha Magnetic Spectrometer is planned for launch in late April. Unlike any previous laboratory in space, the ISS offers a long term platform where scientists can operate experiments rapidly after developing a new research question, and extend their experiments based on early results.

This presentation will explain why having a laboratory in orbit is important for a wide variety of experiments that cannot be done on Earth. Some of the most important results from early experiments are already having impacts in areas such as healthcare, telemedicine, and disaster response. The coming decade of full utilization offers the promise of new understanding of the nature of physical and biological processes and even of matter itself.

Ice Fishing for Neutrinos
Scientists are melting holes in the bottom of the world!

Monday October 12, 2009

Scott Labs Room 0001
7:30pm
201 W 19th Ave

We have melted half of the eighty holes over two km deep in the Antarctic icecap to be used as astronomical observatories. Into each hole is lowered a string knotted with basketball-sized light detectors which are sensitive to the shimmering blue light emitted in the surrounding clear ice when ghostly particles called neutrinos pass through the Earth. These neutrinos are cosmic messengers from the most violent processes in the universe, for example giant black holes gobbling up stars in the heart of quasars, and gamma-ray bursts which are the biggest explosions since the Big Bang. Neutrinos will tell us if there are dark matter particles trapped in the heart of the Sun, and perhaps even reveal if there are additional dimensions in space.

Dr. Francis Halzen is a Hilldale and Gregory Breit Distinguished Professor at the University of Wisconsin, Madison. He is a theoretician studying problems at the interface of particle physics, astrophysics and cosmology. Since 1987, he has been working on the AMANDA experiment, a first-generation neutrino telescope at the South Pole. AMANDA obser- vations represent a proof of concept for IceCube, a kilometer-scale observatory now under construction.

Island Universe

From the Big Bang to Island Universe

Josiah McElheny and David Weinberg

Wednesday May 6, 2009

  • 5:30pm
  • Film/Video Theater
  • (Located in the lower level of the Wexner Center)

  • Over the last four years, MacArthur-award winning artist Josiah McElheny and Ohio State astronomer David Weinberg have collaborated on the design of four cosmologically inspired sculptures. In this joint lecture, McElheny and Weinberg will describe the history of their collaboration and the scientific and philosophical ideas behind these extraordinary art works, which have been exhibited across the United States and Europe.

  • Their work together began with An End to Modernity, a memorable sculpture produced when McElheny was a Wexner Center Residency Award artist and exhibited here in 2005, and is concluding with a five-piece installation titled Island Universe (2008) that's been shown in London and Mardrid.

  • Today, they'll describe the history of their collaboration and the scientific and philosophical ideas behind these extraordinary art works. The presentation concludes with the Columbus premiere of McElheny's recent film, also titled Island Universe (19 mins., Super 16mm film transferred to high definition video).

An End to Modernity

  • Co-sponsored by Wexner Center for the Arts and the Center for Cosmology and AstroParticle Physics (CCAPP). Image Up/Left: Island Universe

  • The sculpture to the left, An End to Modernity was designed in collaboration with CCAPP scientist David Weinberg. McElheny's sculpture traces the 14 billion year history of the expanding universe. The central aluminum sphere, lamps, and glass pieces depict the last scattering surface, the rise and fall of the quasar population, and the growth, transformation, and clustering of galaxies.

  • First exhibited at the Wexner Center for the Arts, An End to Modernity is now in the collection of the Tate Modern gallery in London.

  • Watch a video of artist Josiah Elheny discussing his work.

The View From The Center Of The Universe

March 24, 2008

  • The Ballroom, The Blackwell Inn
  • 5:00-6:00pm
  • 2110 Tuttle Park Place

  • The universe is made mostly of dark matter and dark energy, with visible matter making up only about half a percent of the total. This lecture explains and visualizes this new picture of the universe and its evolution. Joel and Nancy alternate frequently during the presentation, presenting scientific and philosophical viewpoints. They show spectacular new images and videos, using both updated ancient symbols and the latest astronomical data and simulations. They also use humorous cartoons to illustrate how cosmological ideas have cultural implications. The talk is both entertaining and educational, and it can be enjoyed by everyone from people who know nothing about modern astronomy to experts in the field. It is a remarkable fact that humans - and indeed intelligent life anywhere in the universe - must have a size that is in the middle of all possible size scales. Becoming aware of this and other aspects of our special place in the cosmos opens a sweeping new perspective on what we truly may be as humans and what we can do to resolve our personal and global challenges.
