American Journal of Physics, 2016 More than a decade ago, Edwin Taylor issued a “call to action” that presented the case for basing introductory university mechanics teaching around the principle of stationary action [E. F. Taylor, Am. J. Phys. 71, 423–425 (2003)]. We report on our response to that call in the form of an investigation of the teaching and learning of the stationary ...

What tool representation, intuitive physics, and action have in common: The brain’s first-person physics engine [PDF]
Cognitive Neuropsychology, 2021 An overlapping set of brain regions in parietal and frontal cortex are engaged by different types of tasks and stimuli: (i) making inferences about the physical structure and dynamics of the world, (ii) passively viewing, or actively interacting with ...

Geometrical aspects of an Abelian (2,0) action [PDF]
Journal of High Energy Physics, 2020 We explore various geometrical aspects of an action for six-dimensional chiral 2-forms based on the formalism of 1903.12196. We elucidate the coupling to general backgrounds and construct the full supersymmetric completion to an abelian (2, 0 ...

Extremal Kerr Black Holes as Amplifiers of New Physics. [PDF]
Physical Review Letters, 2023 We show that extremal Kerr black holes are sensitive probes of new physics. Stringy or quantum corrections to general relativity are expected to generate higher-curvature terms in the gravitational action.

DexDeform: Dexterous Deformable Object Manipulation with Human Demonstrations and Differentiable Physics [PDF]
International Conference on Learning Representations, 2023 In this work, we aim to learn dexterous manipulation of deformable objects using multi-fingered hands. Reinforcement learning approaches for dexterous rigid object manipulation would struggle in this setting due to the complexity of physics interaction ...

Action research in the physics classroom: the impact of authentic, inquiry based learning or instruction on the learning of thermal physics [PDF]
, 2017 Students experience thermal physics phenomena from a very young age, but in Singapore their formal science instruction occurs in Primary 3 or 4 (aged 9 or 10) and again in secondary school (aged 13 to 16).

Post-Minkowskian radial action from soft limits and velocity cuts [PDF]
Journal of High Energy Physics, 2021 We consider gravitational massive scalar-scalar scattering from unitarity and demonstrate how intermediate soft graviton behavior and the concept of extracting classical physics from localization of integrands on velocity cuts devise an efficient ...

An algorithm for discovering Lagrangians automatically from data [PDF]
PeerJ Computer Science, 2015 An activity fundamental to science is building mathematical models. These models are used to both predict the results of future experiments and gain insight into the structure of the system under study.

EP-PINNs: Cardiac Electrophysiology Characterisation Using Physics-Informed Neural Networks [PDF]
Frontiers in Cardiovascular Medicine, 2021 Accurately inferring underlying electrophysiological (EP) tissue properties from action potential recordings is expected to be clinically useful in the diagnosis and treatment of arrhythmias such as atrial fibrillation.
