re-projecting (Utrecht) Event 4: Me and You
Me and You Choreographies, Games and Exercises
Groups are invited to wear shirts with the printed pronouns ‘me’ and ‘you’. The proposal is always to perform games and exercises developed collectively (although sometimes prepared instructions can be used). It is a piece about group dynamics that is always referred as ‘person or group specific’. Every time the results differ, according to the people who take part and the groups that are constituted during the time we practice together. The results are brought about in two different directions: one record is established in terms of body-memory, accessible only to the ones who shared the intensity of the experience, being refractory to documentation; the other, its opposite, is constituted through the images and videos produced during the actions.
The aim is to understand the evolution of the system (person or electron) in time, taking into account the existence of the others. In this approach, the question of You and Me (two-body problem) is the first aim to be understood. This project involves the gesture of writing with the participant's bodies. A narrative is produced, one that is read at the same time it is performed and which constitutes the experience of the group exercise: the words are the visible signs (remember: pronouns are "shifters", getting their meaning according to the context and the act of speech) by which intensity is modulated, and the new "bodies in motion" can be designed by the close encounter between discursive and non-discursive strategies.
Lecture on Pedestrian Flows
The analysis of pedestrian flows is becoming an important part of the planning and the design of public areas and large buildings. This is originated by the necessity to improve the quality of walking facilities from the pedestrian perspective and by the necessity to determine the safety levels of these areas in emergency situations. The behaviour of pedestrians can be modelled and simulated macroscopically or microscopically. The distinction between them is the representation of pedestrians. Macroscopic models do not describe the pedestrians individually but use aggregated variables like flows or queues, while microscopic agents treat pedestrians as individual entities. The type of modelling chosen depends on the type of analysis of pedestrian flows that has to be done. In the Nomad microscopic pedestrian model the pedestrians are autonomous agents that are modelled according to three behavioural levels: Strategic, Tactical and Operational.
Lecture on Theoretical Physics and Diagrams
The field of research is the so-called Many-Body Quantum Physics. In simpler terms, it is about the "sociology of electrons". Electrons are one of the constituents of the atoms, which on their turn are the small building blocks behind all kinds of matter. Remarkably, an ensemble of interacting electrons behave very differently than a single individual one. One of the biggest challenges of Modern Quantum Physics is to describe the interactions between electrons, and at the same time, how do they interact with impurities (or perturbations) in the environment. Physics relies strongly on Mathematics to express the behavior of this bunch of electrons. However, the corresponding equations are terribly long and complicated and one needs to find a correct though simplified way to express their collective behavior. The solution to this dilemma is provided by Diagrams. Precisely as in art, a diagrammatic representation is a universal, correct, and simple way to express how an individual (electron) interacts with other individuals (electrons) and with external perturbations (impurities).
