Much of what I heard, however, seemed to come from an inverted world, the axis spinning backward, all the essential story lines turned inside out.
Isolated in my riverside reverie it would be easy to forget that we are hurtling through space, on a planet that is tilted over on its axis, spinning as we go, travelling on an orbit that takes us closer and then further from the Sun.
Centrifugal expansion happens when the axis spins in one direction and contraction happens when centripetal forces spin in the opposite direction.
This season the double-cork 1080, an inverted off-axis spin of three rotations, has divided the men's halfpipe field.
Although no one has performed the double cork, an off-axis spin, in a halfpipe, "that is probably going to be the next step," Fisher said.
Howell unleashed a switch-900 an off-axis spin that includes 2 ½ rotations during a run that finished with a score of 94.20, trouncing the rest of the field on a warm and sometimes frightening day.
Torah Bright of Australia, a strong contender for an Olympic medal in the women's halfpipe, sent a buzz through the snowboarding world in recent weeks when she announced that she had been practicing a double-cork 900 — an off-axis spin of two and a half rotations that has never been landed in competition by a woman.
Figure 2 describes their geometry in (a) the external view and (b) the view from the Z-axis (spin axis), with the definition of Arase's coordinates.
With Boys Noize and Lil Wayne cranking on the loudspeakers and the Colorado crowd cheering, they threw aerial tricks like off-axis spinning double-back flips and switch 1080s — three 360-degree spins with backward takeoffs.
As Titan orbits Saturn, Titan is slowly spinning on its axis, one spin for each trip around Saturn.
