PIRSA:09050048  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The Drunkard's Walk
Speaker(s): Leonard Mlodinow
Abstract: In The Drunkard's Walk, acclaimed writer and scientist Leonard Mlodinow shows us how randomness, change, and probability reveal a tremendous amount about our daily lives, and how we misunderstand the significance of everything from a casual conversation to a major financial setback. As a result, suc... read more

The Universe from Beginning to End
Speaker(s): Brian Schmidt
Abstract: Astronomers believe our Universe began in a Big Bang, and is expanding around us. Brian Schmidt will describe the life of the Universe that we live in, and how astronomers have used observations to trace our Universe's history back more than 13 Billion years. With this data a puzzling picture has be... read more

Top Quark: The Elusive Truth
Speaker(s): Michael Peskin
Abstract: The top quark is the heaviest known type of quark, and possibly the last. Particle physicists sometimes refer to it as the "truth” quark, not always with tongue in cheek. The top quark might be just an ordinary quark, no stranger than the "strange" one, but it might hold the key to major questions... read more

The Robotic Scientist: Mining experimental data for scientific laws, from cognitive robotics to computational biology
Speaker(s): Hod Lipson
Abstract: For centuries, scientists have attempted to identify analytical laws that underlie physical phenomena in nature. Despite today’s computing power, the process of finding natural laws and their corresponding equations has resisted automation. A key challenge to finding analytic relations automatical... read more

PIRSA:10030119  ( MP4 Medium Res , MP3 , PDF ) Which Format?
The quantum world: from weird to wired
Speaker(s): Joseph Emerson
Abstract: Does quantum mechanics really tell us that particles, molecules, and maybe even cats, can be in two places at once? Does it force us to deny a reality that is independent of our observation? How can scientists disagree about what quantum mechanics means and yet still agree that it is right? Joseph E... read more

The Science of Galaxy Zoo, or What 250,000 astronomers can tell us about the Universe
Speaker(s): Chris Lintott
Abstract: Since its launch in 2007, the website Galaxy Zoo (www.galaxyzoo.org) has become the largest astronomical collaboration in history, involving more than 250,00 volunteers in classifying galaxies. Humans outperform computers at this kind of visual classification, and the results from Galaxy Zoo have be... read more

Searching for the Quantum Origins of Space and Time
Speaker(s): Renate Loll
Abstract: Einstein's theory of General Relativity has taught us that empty space (or, more precisely, spacetime) is in itself a dynamical and wonderfully rich entity for both theoretical physicists and science fiction authors alike. Although it may stretch our imagination, astrophysical observations leave lit... read more

The Ubiquitous Bell Curve: What it does and doesn't tell us
Speaker(s): John Mighton
Abstract: The Bell Curve is an extremely beautiful and elegant mathematical object that turns up – often in surprising ways – in all spheres of human life. The Curve was first used by astronomers to correct errors in their observations, but it soon found important applications in the social and medical sc... read more

Why did Isaac Newton Believe in Alchemy?
Speaker(s): William Newman
Abstract: Isaac Newton is known today as one of the most profound scientists to have ever lived. Newton's discoveries in physics, optics, and mathematics overturned a variety of fundamental beliefs about nature and reshaped science in ways that are still powerfully with us. But this is only part of Newton's f... read more

Quantum Life
Speaker(s): Seth Lloyd
Abstract: Recent experimental evidence suggests that living organisms are using quantum mechanics in a sophisticated fashion to enhance the efficiency of photosynthesis. Bacteria are essentially performing a quantum computation to extract energy from light. I will show how plants and bacteria perform quantum ... read more
