Where does technology come from? Physics! Exploring basic mysteries such as "What is light?", "How can atoms exist?", and "What is space and time?" led to computers, wireless communication, mp3 players, lasers, medical imaging - indeed, virtually every "high tech" device on the planet. Join us in a celebration of the immense power of theoretical physics to transform our world for the betterment of humanity, and learn how current theoretical explorations may hold potential for even more fantastic innovations in the future.

The mysteries of quantum theory run deep. Despite 80 years of research, there is still no consensus on its interpretation. This talk will explore some of the important issues in the foundations of quantum theory, from the idea that we have only a limited knowledge of a deeper reality, like the prisoner in Plato’s cave who sees only the shadows of objects and never the objects themselves, to John Bell’s famous discovery of the difference between quantum correlations and Dr. Bertlmann’s socks, namely, that whereas the mismatched colours of the doctor’s socks can be attributed to a decision at the sock drawer that morning, certain quantum correlations cannot be explained by a common cause, at least not without doing violence to some cherished principles of physics, such as the fact that causes cannot travel faster than the speed of light.

Our understanding of the physical world at the most fundamental level is based on two theories: quantum theory and general relativity. They are impressively successful when each is considered on its own, but in situations where both play a role, we are reduced to puzzles and absurdity. To the great frustration of researchers, candidate theories of quantum gravity produce more puzzles than answers. We shall tour of some of the problems, focusing on the role of spacetime and causality. We will consider the possibility that spacetime did not always exist but is instead emergent and explore how one can create a spacetime from a world with no notion of "here" and "there".

In this closing session, festival panelists will look back over the preceding ten days to review what we've learned about the Quantum, the Cosmos, and Ideas for the Future.
