If a Tree Falls: The Physics of What Happens and Who Is Listening

WEDNESDAY, AUGUST 17, 2016

6:30PM – 8:30PM Welcome Reception

THURSDAY, AUGUST 18, 2016

8AM – 9AM Breakfast

9AM – 12PM Intro Panel: Dirty Secrets

Introductory session to uncover the hidden-in-the-attic issues, brushed-under-the-rug assumptions, and embarrassing unsolved problems in: cosmology, quantum mechanics, quantum gravity, science of life, artificial intelligence, and consciousness. These these talks will also will review each of these topics, while shining particular light on issues concerning treatment of “events” and “observers.”

Speakers:

12PM Boxed Lunch (take on excursion)

12PM (varies) – 4PM Breakout Sessions Off-site

4PM-6PM Session 2: QM Experiments

This session will explore the latest and greatest in experimental probes of quantum reality, ranging from quantum computing to macroscopic entanglement to much more. What do experiments tell us about the nature of quantum events and observers?

Speakers:

Moderator: Seth Lloyd

Panelists: Andrew BriggsAlberto PeruzzoRaj PatelTim Taminiau

6PM-7PM Lightning Talks 1

FRIDAY, AUGUST 19, 2016

8AM – 9AM Breakfast

9AM – 12PM Session 1: What’s an Event?

This session will explore the concept of an “event.” What is an event at the quantum level? What does it mean for something to “happen” in fundamental physical theories with unitary dynamics? Can things “unhappen,” and how? When are events objective happenings and when are they observer dependent?

Speakers:

  • Charles BennettOccam’s Razor, Boltzmann’s Brain and Wigner’s Friend in Equilibrating and Non-Equilibrating Cosmologies
  • William UnruhEffect of Measurement on Location of a Quantum Event
  • Sean CarrollWhat Happens Inside the Wavefunction? (YouTube)

Moderator:  Andrew Briggs

Panelists: Emily AdlamClaus KieferMairi Sakellariadou

12PM – 1PM Lunch

1PM – 4PM Session 2: What’s the Gap Between Life and Non-life?

What separates physical systems with agency from those without it? How is agency compatible (or not) with deterministic physical laws? What sorts of physical systems can be considered agential, alive, observers, conscious – and which ones can’t? How should we think about free will?

Speakers:

Moderator: Anthony Aguirre

Panelists: Joscha BachPaul DaviesBart SelmanSusanne Still

4PM – 5PM Lightning Talks 2

5PM – 7PM Breakout Sessions (on your own)

7PM Public Event: Speed Dating Science at Banff Public Library

SATURDAY, AUGUST 20, 2016

8AM – 9AM Breakfast

9AM – 12PM Session 1: What’s an Observer?

What are the capabilities of “observers” required by various theories, and what systems have these capabilities? Where can we go wrong in ignoring properties of the observers, and how? Is there a physics without observers? Is there an observer-centered physics?

Speakers:

  • Jim HartleThe Return of the Observer
  • Susanne StillOptimal Information Processing as an Observer’s Way to Represent Information (YouTube)
  • David WolpertObservers as Systems That Exploit Information About the Environment to Stay out of Equilibrium (YouTube)

Moderator: Adam Brown

Panelists: Alan GuthAdrian KentDavid Wallace

12PM Boxed Lunch (take on excursion)

12PM – 4PM Breakout Sessions off-site

4PM – 7PM Session 2: Science & Society

This session will delve into the relationships between science and society. How does each category impact the other? What are the responsibilities of scientists towards larger society, and what does science need from society? We may be at a crucial, existential juncture in human history. What role does/will/should science play?

Moderator: Max Tegmark

Panelists: TBD

SUNDAY AUGUST 21, 2016

8AM – 9AM Breakfast

9AM – 12PM Session 1: What Exists?

Black hole interiors; the region outside of cosmological horizons; spacetime itself; the quantum statevector; “information”; “infinity”; the “self”; consciousness. These among many other things have an ontological status under active, rigorous debate – with some ascribing quite fundamental reality to them, and others seeing them as emergent, subjective, or even illusory. This session delves in.

Speakers:

  • Raphael BoussoWhat Exists and What Happens: The Role of the Observer
  • Steve GiddingsWhat Exists in the Quantum Universe – Observation in Gravitational Systems (YouTube)
  • Jenann IsmaelWhy Physics Should Care About the Mind, and How to Think About It Without Worrying About the Hard Problems

Moderator: Carlo Rovelli

Panelists: Andreas AlbrechtBianca DittrichLaura Mersini-HoughtonDon Page

12:00PM – 12:15PM Group Photo

12:15PM – 1:15PM Lunch

1PM – 4PM Breakout Sessions (on your own)

4PM – 7PM Session 2: Consciousness

This session will explore the nature of consciousness, including efforts to define and measure it. What systems have subjective experience? What do we mean when we refer to various types of consciousness? How simple, and how sophisticated, can consciousness in principle be? Can we define necessary conditions for a physical system to be conscious? Sufficient conditions?
