Less apparent than the swirling movement, which is more about energetic impulse than shape, are the extreme changes in speed and the way in which Mr. Forsythe braids tension with bodies.
Even so, Ms. Mahler's austere investigations have less to do with creating a narrative world than with the juxtaposition of stillness and the energetic impulses that propel movement into action.
The paid series began in April 1858, the immediate impulse being to find some energetic distraction from his marital unhappiness.
The usual approach is to seek more energetic propellants with high specific impulse ("Isp" the number of seconds a pound of fuel can be made to deliver a pound of thrust) values.
He found a kindred soul in Alex Westerman, an energetic former art director who on an impulse had quit a job working for a children's television show to found a Web site called Radical Zoo.
Secondly, the angle of take-off from the compliant surface during 1.8 m jumps is closer to the optimal for energetic efficiency (45°), possible due to the impulse provided by the surface as it returns stored energy during the final stages of the take-off.
Both shows are slick, energetic stories about cable-news pundits with lousy impulse control, advice-givers with high standards for everyone but themselves.
Being irrepressibly energetic and playful, children need room to express their impulses and imaginations, which do not always align with adult, bourgeois strictures of behavior.
However, there is a better chance that radio-loud CMEs produce an energetic storm particle event (Mäkelä et al. 2011) and strong sudden commencement/sudden impulse (Veenadhari et al. 2012), suggesting that stronger shocks near the Sun do matter.
Vesicles are also released from oligodendrocytes, the glial cells responsible in the CNS for producing the myelin sheath which coats the axons, allowing fast impulse conduction; in addition, like astrocytes, oligodendrocytes have a trophic function and provide neurons with energetic substrates, such as lactate [ 42– 42].
