ASAP: Aligning Simulation and Real-World Physics for Learning Agile Humanoid Whole-Body Skills

arXiv.org
Humanoid robots hold the potential for unparalleled versatility in performing human-like, whole-body skills. However, achieving agile and coordinated whole-body motions remains a significant challenge due to the dynamics mismatch between simulation and ...

Physics in action - visiting a hospital

Physics Education, 1989
Very often, an appreciation of a technological application cannot be gained without actually seeing `the real thing' in action. To this end, this article describes the preparation for and organisation and evaluation of a visit to a hospital.

Part I: Physical Insight Into Carbon-Doping-Induced Delayed Avalanche Action in GaN Buffer in AlGaN/GaN HEMTs

IEEE Transactions on Electron Devices, 2019
Physics behind the improvement in breakdown voltage of AlGaN/GaN HEMTs with carbon-doping of GaN buffer is discussed. Modeling of carbon as acceptor traps and self-compensating acceptor/donor traps is discussed with respect to their impact on avalanche ...

Experimental extraction of the quantum effective action for a non-equilibrium many-body system

Nature Physics, 2019
On the fundamental level, quantum fluctuations or entanglement lead to complex dynamical behaviour in many-body systems 1 for which a description as emergent phenomena can be found within the framework of quantum field theory. A central quantity in these

Physicalism, Action, and Explanation

1993
Abstract Naturalism, construed broadly, states that whatever exists is part of the natural order of things. One common understanding of the natural order implies that whatever is natural is explainable, at least in principle, by the natural sciences.

The Social Meaning of Physical Action

2013
Intelligent systems should be able to initiate and understand social interactions, which are always brought about by physical actions. Thus, all physical actions need to be interpreted for their social effects. This paper gives an analytical framework that identifies the main challenges in modelling social interactions.

Availing the Physics of Least Action

New Literary History, 1995
Amidst the talk about totality of language?its logic, its rhetoric, its aesthetics, its politics?there persists an unapparent action that we do every day. Like Wittgenstein's language games that we use as commonplace, this kind of action seems not to have a locutionary figure of speech, perhaps because we do it unskeptically.

Orientations of the actions of physics teachers

International Journal of Science Education, 1989
Although teachers’ thinking and their subjective (implicit) theories have been investigated for many years, little research has been carried out into teachers’ thinking and decision‐making in specific areas. This paper describes the main orientations of physics teachers that are assumed to be typical for this subject.

Pipe organs: physics in an action

Physics World, 2002
The pipe organ is the most impressive of all musical instruments, often reaching heights of metres or even tens of metres in concert halls and churches. One of the most crucial parts of the organ is the "action" – the mechanism that links the keys and the pipes.

Action at a Distance in Physics and Cosmology

Physics Bulletin, 1975
F Hoyle and J V Narlikar Reading: W H Freeman 1974 pp x + 266 price £7.80 Neither of these authors has shirked controversy in the past and this together with their undoubted ability to write in an attractive way made the review of this book an exciting prospect. I was not disappointed.
