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 ...

Geometric and physical interpretation of the action principle
Scientific Reports, 2023 AbstractWe give a geometric interpretation for the principle of stationary action in classical Lagrangian particle mechanics. In a nutshell, the difference of the action along a path and its variation effectively “counts” the possible evolutions that “go through” the area enclosed.

Physical and observational practices of unusual actions prime action verb processing [PDF]
Brain and Cognition, 2020 Numerous studies have highlighted a strong relationship between language and sensorimotor processes, showing, for example, that perceiving an action influences subsequent language processing. Moreover, previous studies have demonstrated that the context in which actions are perceived is crucial to enable this action-language relationship. In particular,

An action-related theory of causality [PDF]
, 2005 The paper begins with a discussion of Russell?s view that the notion of cause is unnecessary for science, and can therefore be eliminated. It is argued that this is true for theoretical physics, but untrue for medicine where the notion of cause plays a ...

A Biofeedback Game with Physical Actions [PDF]
, 2010 We developed a biofeedback game in which players can take other physical actions besides simply "relaxing". We used the skin conductance response for sensing a player's surge of excitement and penalized players when they did not attack enemies in situations because they were not calm enough to meet the biofeedback threshold.

Four-Dimensional Supergravities from Five-Dimensional Brane Worlds [PDF]
, 2001 We give the explicit form of the four dimensional effective supergravity action, which describes low energy physics of the Randall-Sundrum model with moduli fields in the bulk and charged chiral matter living on the branes. The relation between 5d and 4d
