Quantum gates
Jon Yard - Institute for Quantum Computing (IQC)
Fault-tolerant quantum computers will compute by applying a sequence of elementary unitary operations, or gates, to an error-protected subspace. While algorithms are typically expressed over arbitrary local gates, there is unfortunately no known theory that can correct errors for a continuous set of… -
Mario Livio: Brilliant Blunders
Even the greatest scientists have made some serious blunders. "Brilliant Blunders" concerns the evolution of life on Earth, of the Earth itself, of stars, and of the universe as a whole. In this talk, astrophysicist Dr. Mario Livio will explore and analyze major errors committed by such luminaries… -
The Dawn of Gravitational Wave Astronomy
Chad Hanna - Pennsylvania State University
100 years after the existence of gravitational waves was first postulated by Albert Einstein, the LIGO and Virgo Collaborations detected gravitational waves for the first time on September 14, 2015. The gravitational waves originated from a pair of black holes that merged over one billion years ago… -
Growth dynamics and scaling laws across levels of biological organization.
Ian Hatton - McGill University
Recent findings on quantitative growth patterns have revealed striking generalities across the tree of life, and recurring over distinct levels of organization. Growth-mass relationships in 1) individual growth to maturity, 2) population reproduction, 3) insect colony enlargement and 4) community… -
Translating quantum gravity for the massless
James Sully - McGill University
Recent developments in our understanding of black hole evaporation and the information paradox suggest that effects from quantum gravity are not necessarily hidden at the Planck scale. They might even one day be testable by gravitational wave measurements. To prepare ourselves, we must first… -
Entanglement of spacetime
William Donnelly - EA
Entanglement is both a central feature of quantum mechanics and a powerful tool for studying quantum systems. Even empty spacetime is a highly entangled state, and this entanglement has the potential to explain puzzling thermodynamic properties of black holes. In order to apply the methods of… -
Tim Palmer: Climate Change, Chaos and Inexact Computing
Tim Palmer - University of Oxford
How well can we predict our future climate? If the flap of a butterfly’s wings can change the course of weather a week or so from now, what hope trying to predict anything about our climate a hundred years hence? In this talk I will discuss the science of climate change from a perspective which… -
P-adic Integers and Quantum Reality: Towards a realistic locally causal theory of fundamental physics.
Tim Palmer - University of Oxford
Almost the first thing we learn as human beings is a sense of spatial awareness: the smaller the Euclidean distance between two objects, the closer they are. As adults, we apply this deeply held intuition to state space. In particular, as philosopher David Lewis made explicit in his seminal 1973… -

What drives weather changes?
Gregory Falkovich - Weizmann Institute of Science
Winds are driven by the gradients of solar heating. Vertical gradients cause thermal convection on the scale of the troposphere depth (less than 10 km). Horizontal gradients excite motions on a planetary (10000 km) and smaller scales. Weather is mostly determined by the flows at intermediate scale…
