The Brain, the Broken Brain & the Neural Biology of Language

Speaker:

Steven Small

My laboratory focuses on understanding how the human brain produces and comprehends language, and how the motor functions of the hands and mouth achieve goal-directed actions, such as speech and gesture. By  investigating the neural bases of language and hand motor function  using a variety of methods, such as computational modeling, functional  and structural brain imaging, and cognitive assessment, we have been  able to understand better the biology of language and to develop novel  treatment approaches for language disorders.

Chasing Cosmic Bullets

Speaker:

Angela Olinto

The most energetic particles in the universe are ultra-high energy 
cosmic rays. They are strange beasts: millions of times more powerful than anything produced by man-made accelerators, concentrated (e.g., one can pack the energy of a fastball into a subatomic particle), and very rare (they occur once/sq km/century). The nature and origin of  these cosmic bullets has been a scientific mystery for a century. Recently, an international collaboration of 17 countries joined forces to solve this mystery by building the Pierre Auger Observatory, which is spread over 3,000 square kilometres in the Pampas of Argentina. Auger has captured enough of these rare particles to find the first clues to their origins, which seems to be  from nearby galaxies that host super massive black holes. Auger scientists continue to study these most extreme particles to learn where they come from, what they are made of, and how they are accelerated to such enormous energies.

Looking for Dark Matter through the Bottom of a Wine Glass
 

Speaker:

Evelyn Gates

What is the Universe made of?

New data insist that normal matter  –  everything you were ever taught in chemistry class  –  makes up only about 5% of the total amount of matter and energy in the Universe. Dark Matter, an exotic new form of matter that has never been directly detected, accounts for about 23%, while the remaining 72% is not matter of any kind, but some strange new substance, dubbed Dark Energy, that is fueling an accelerated  expansion of space itself. The search for dark matter and dark energy is complicated by the fact that they cannot be seen directly with even our most powerful telescopes. Instead, cosmologists are using the warps and dimples in space-time described by Einstein in his theory of  General Relativity as giant "cosmic lenses".  Gravitational lensing – also known as Einstein’s Telescope – allows us to probe the dark Universe in an entirely new way:  to search for black holes and planets within our own Galaxy, map out the dark matter that dominates a galaxy or cluster of galaxies, and detect the imprint of dark energy on the web of dark matter that winds across the cosmos.

The Warped Side of the Universe

Speaker:

Kip Thorne

Poster available

Our Universe has a "warped side": objects and phenomena that are made not from matter, but rather from warped space and warped time.   
Examples include black holes, and the big-bang singularity from which the Universe was born. Thorne will discuss this mysterious warped side, the quest to simulate it using supercomputers, and the quest to observe it using gravitational waves and strange telescopes.

A Cosmic Road Trip: Chicago to the South Pole to the Edge of the Universe

Speaker:

Tom Crawford

By making maps of (quite literally) the farthest edge of the visible Universe, the 10-meter South Pole Telescope (SPT) is unlocking some of the deepest mysteries in science, including the nature of the strange form of mass-energy that seems to dominate the Universe and be responsible for its accelerated expansion. Join a conversation about the telescope and the science it is delivering, intertwined with a personal perspective on what it's like to travel to the most remote 
location on Earth to build a 269 ton telescope on top of Antarctic ice.
