Science Education International, 2020 Newton’s third law of motion is probably one of the easiest and simplest laws in physics for students to recite. However, when they are given questions where they must apply the understanding of the law to solve a problem, it often becomes a challenge ...

Fictional metaphysics of fiction: Metaphysics and imagination in the humanities
HTS Teologiese Studies/Theological Studies, 2017 A very simplified description of physics could be, according to Wikipedia, natural science that involves the study of matter and its motion and behaviour through space and time.

Geometrical Field Formulation of Thermomechanics in Rational Mechanics [PDF]
arXiv, 2010 In modern science, the thermo mechanics motion can be traced back to quantum motion in micro viewpoint. On the other hand, the thermo mechanics is definitely related with geometrical configuration motion (phase) in macro viewpoint. On this sense, the thermomechanics should be formulated by two kinds of motion: quantum motion and configuration motion ...

A simple superluminal but not physical motion
, 2007 We discuss a superluminal unphysical motion which, we believe, has a high pedagogical potential. It highlights the physics behind the concept of simultaneity in special relativity and illustrates the non-physical character of superluminal speeds offering a rewarding exercise in handling the Minkowski space-time diagram.

Physical Review Special Topics. Physics Education Research, 2014 In our pilot studies, we found that many introductory physics textbook illustrations with supporting text for sound standing waves of air columns in open-open, open-closed, and closed-closed pipes inhibit student understanding of sound standing wave ...

The basis of discontinuous motion [PDF]
arXiv, 2002 We show that the instant motion of particle should be essentially discontinuous and random. This gives the logical basis of discontinuous motion. Since what quantum mechanics describes is the discontinuous motion of particles, this may also answer the question 'why the quantum?'.

Journal of Advances in Modeling Earth Systems, 2018 A set of idealized experiments are developed using the Community Atmosphere Model (CAM) to understand the vertical velocity response to reductions in forcing scale that is known to occur when the horizontal resolution of the model is increased.

Non-rigid 3D motion estimation at high temporal resolution from prospectively undersampled k-space data using low-rank MR-MOTUS [PDF]
arXiv, 2020 With the recent introduction of the MR-LINAC, an MR-scanner combined with a radiotherapy LINAC, MR-based motion estimation has become of increasing interest to (retrospectively) characterize tumor and organs-at-risk motion during radiotherapy. To this extent, we introduce low-rank MR-MOTUS, a framework to retrospectively reconstruct time-resolved non ...
