The essays during this booklet examine the query of no matter if physics may be in accordance with info, or – as John Wheeler phrased it – no matter if we will be able to get “It from Bit”. they're in response to the prize-winning essays submitted to the FQXi essay festival of a similar identify, which drew over a hundred and eighty entries.
The eighteen contributions tackle subject matters as diversified as quantum foundations, entropy conservation, nonlinear common sense and countable spacetime. jointly they supply stimulating examining for all physics aficionados drawn to the prospective role(s) of knowledge within the legislation of nature.
The Foundational Questions Institute, FQXi, catalyzes, helps, and disseminates examine on questions on the foundations of physics and cosmology, rather new frontiers and leading edge principles indispensable to a deep realizing of fact, yet not going to be supported by way of traditional investment sources.

Drawing Quantum Contextuality with ‘Dessins d’enfants’ Michel Planat1 (1)Institut FEMTO-ST, CNRS, 15 B road des Montboucons, 25044 Besançon, France Michel Planat e-mail: michel. planat@femto-st. fr summary within the general formula of quantum mechanics, there exists an inherent suggestions of the dimension atmosphere at the effortless item less than scrutiny. therefore one can't imagine that an ‘element of fact’ prexists to the size and, it truly is much more interesting that unperformed/counterfactual observables input the sport. this can be known as quantum contextuality. basic finite projective geometries are so that it will photo the commutation kin of quantum observables getting into the context, at the least for platforms with or 3 events. within the essay, it really is additional came upon a mathematical mechanism for ‘drawing’ the contexts. The so-called ‘dessins d’enfants’ of the prestigious mathematician Alexandre Grothendieck function workforce, graph, topological, geometric and algebraic homes of the quantum contexts that will differently were ‘hidden’ within the obvious randomness of size results. creation the incentive for being attracted to the subject of quantum contextuality dates again the prestigious Bohr-Einstein discussion concerning the basic nature of quantum truth. the 1st sentence of the Einstein-Podolski-Rosen (EPR) paper  is as follows If, with out in any respect tense a procedure, we will are expecting with walk in the park (i. e. , with chance equivalent to cohesion) the price of a actual volume, then there exists a component of actual fact akin to that actual volume.
