Fisidabo at the European Journal of Physics: Modelling human behaviour in a bumper car ride using molecular dynamics tools: a student project

A partir dels resultats obtinguts a un dels experiment Fisidabo 2013 realitzat per Jorge J. Buendía, Hector Lopez i Guillem Sanchis, quan feien el primer curs del grau en enginyeria física, aquests estudiants i el professor del grau Luis Carlos Pardo han publicat un article al European Journal of Physics 38 035802 titulat Modelling human behaviour in a bumper car ride using molecular dynamics tools: a student project.



Amusement parks are excellent laboratories of physics, not only to check physical laws, but also to investigate if those physical laws might also be applied to human behaviour. A group of Physics Engineering students from Universitat Politècnica de Catalunya has investigated if human behaviour, when driving bumper cars, can be modelled using tools borrowed from the analysis of molecular dynamics simulations, such as the radial and angular distribution functions. After acquiring several clips and obtaining the coordinates of the cars, those magnitudes are computed and analysed. Additionally, an analogous hard disks system is simulated to compare its distribution functions to those obtained from the cars' coordinates. Despite the clear difference between bumper cars and a hard disk-like particle system, the obtained distribution functions are very similar. This suggests that there is no important effect of the individuals in the collective behaviour of the system in terms of structure. The research, performed by the students, has been undertaken in the frame of a motivational project designed to approach the scientific method for university students named FISIDABO. This project offers both the logistical and technical support to undertake the experiments designed by students at the amusement park of Barcelona TIBIDABO and accompanies them all along the scientific process.
