Amid the clouds of unpredictable change, there always seems to be a sliver of light - of hope - on the horizon. However, in Chandler's estimation, the fundamental insight to be gained in the Anthropocene is that ours is a world without the privilege of hope. Hope (seemingly) provides opportunities and encourages action even though the (un)intended result may be a harsher constraint, as the articles of Guerrieri, Ottendörfer and Chandler note. As he demonstrates, the historical and philosophical perspective of hope as a desire for "alternative possible outcomes" (Chandler, [4]) lives on in the Anthropocene. [Extracted from the article]

We study numerically orientation of rigid fibres in a turbulent flow. Instead of a Lagrangian approach, i.e. following fibres along trajectories and analyzing orientations after simulations, we are using a fibre orientation probability distribution (FOPD) model. The mathematical model predicting the two spherical orientation angles (in a three-dimensional computational domain) is presented and solved in a coupled manner, which is the novelty of our approach. Furthermore, numerical predictions are validated with experiments. The origin of the problem is in the papermaking industry, that is, distributing and orienting fibres optimally into a paper sheet produced. [ABSTRACT FROM AUTHOR]
