3D-printed experimental devices for teaching dynamical systems in physics
Mario Silva, Victoria López, Daniel Freire +1
We present the design, construction and classroom use of 3D-printed experimental devices aimed at introducing dynamical systems in physics courses. Theoretical, technical and pedag…
Multiple harmonics from a hand-struck tube: a simple and precise measurement of the speed of sound
Francisco Echegorri, Martin Monteiro, Cecilia Stari +1
The speed of sound in air can be determined from the resonance frequencies of the harmonic waves inside a thin cylindrical tube. A pressure wave is generated in the tube by strikin…
AI-Assisted Assessment of Experimental Physics Laboratory Reports: Potential, Limitations, and Support for Teaching Practice
Marcos Abreu, Cecilia Stari, Arturo C. Marti
The incorporation of AI into the assessment of physics laboratory reports offers opportunities to support the review of student work and the provision of feedback. This article rev…
Stable levitation of ring magnets: A low-cost, 3D-printed experiment on the magnetic force-distance law
M. Flores, A. Kahrs, F. Rinderknecht +1
Magnetic levitation is one of the most captivating phenomena in physics, combining a striking visual appeal with the rich underlying physics of forces and interactions in equilibri…
Uniform and Accelerated Circular Motion with a Smartphone: A No-Code, AI-Generated Browser Laboratory
Josep Ll. Suñer, Francisco M. Muñoz-Pérez, Juan C. Castro-Palacio +4
Smartphones have become a standard measurement instrument in the physics laboratory. Their built-in accelerometers, gyroscopes, magnetometers, and cameras have been used to investi…

Enhancing Kinematics Understanding through a Video Game Based on Real-Time Motion Graphs
Mateo Dutra, Marcos Abreu, Martín Monteiro +4
Interpreting kinematic graphs remains a significant challenge in physics education. The MissionMotion Project addresses this issue by providing a gamified physical-computational en…
Light intensity does not always decay with the inverse of the square of the distance: an open-inquiry laboratory
Cecilia Stari, Marcos Abreu, Martín Monteiro +1
The square inverse law with distance plays an important role in many fields of physics covering electromagnetism, optics or acoustics. However, as every law in physics has its rang…
Basin of attraction organization in infinite-dimensional delayed systems: a stochastic basin entropy approach
Juan P. Tarigo, Cecilia Stari, Arturo C. Marti
The Mackey-Glass system is a paradigmatic example of a delayed model whose dynamics is particularly complex due to, among other factors, its multistability involving the coexistenc…
Magnetic field of a linear octupole
E. Arribas, I. Escobar, R. Ramirez-Vazquez +4
We measure the magnetic field produced by a linear octupole formed by four magnets placed in such a way that both their magnetic moments and their quadrupole moments cancel each ot…
Basin entropy as an indicator of a bifurcation in a time-delayed system
Juan Pedro Tarigo, Cecilia Stari, Cristina Masoller +1
The basin entropy is a measure that quantifies, in a system that has two or more attractors, the predictability of a final state, as a function of the initial conditions. While the…
Learning difficulties among students when applying Ampère-Maxwell's law and its implications for teaching
Álvaro Suárez, Arturo C. Marti, Kristina Zuza +1
We investigate learning difficulties among second-year students on electromagnetism courses when they apply Ampère-Maxwell's law. Using phenomenography, we analysed written answers…
Using smartphone pressure sensors to measure vertical velocities of elevators, stairways, and drones
Martin Monteiro, Arturo C. Marti
We measure the vertical velocities of elevators, pedestrians climbing stairs, and drones (flying unmanned aerial vehicles), by means of smartphone pressure sensors. The barometric…
Random Delays and the Synchronization of Chaotic Maps
Cristina Masoller, Arturo C. Marti
We investigate the dynamics of an array of logistic maps coupled with random delay times. We report that for adequate coupling strength the array is able to synchronize, in spite o…
Delay-induced Synchronization Phenomena in an Array of Globally Coupled Logistic Maps
A. C. Martí, C. Masoller
We study the synchronization of a linear array of globally coupled identical logistic maps. We consider a time-delayed coupling that takes into account the finite velocity of propa…
