Okay, now all I have to do is rotate it vertically until the lights turn off.

好了，现在我只需垂直体，直到绿灯熄灭。

Tornadoes are whirling, vertical air columns that form from thunderstorms and stretch to the ground.

龙卷风是垂直气柱， 由雷暴形成并延伸到地面。

It is perpendicular to that axis of rotation.

它垂直于那个轴。

It goes up vertically, turns 90 degrees and goes into your hip bone.

它垂直上升， 90 度并进入您髋骨。

You rotate the first circle so that 1 ends up where q was, and rotate the perpendicular circle by the same amount.

第一个圆， 使 1 位于 q 所在位置，然后将垂直圆相同量。

I have the most fuzzy memories of watching him complete his 900 with two and a half vertical spins high above a half pipe.

我模糊记得看他完成那900度翻，他在U型池上方做了两圈半垂直。

And just like the spinning top pointing against the downward force of gravity to stay vertical, the spinning football wants to push against the main force acting against it.

就像陀螺与向下重力相反以保持垂直一样，榄球想要推动作用于它主要力量。

So over time, through collisions and crashes, the cloud loses its loft and flattens into a spinning, roughly 2 dimensional disk shape, like a solar system or a spiral galaxy.

所以，随着时间推移，通过碰撞和崩解，星云失去了它垂直于平面上粒子高度变成扁平状（大概是二维圆盘），就像太阳系或螺星系。

It is simply the product of that lever arm which is going to be a vector, it has to be perpendicular to that axis of rotation.

它只是杠杆臂乘积， 是一个矢量，必须垂直于轴。

Geometrically, a four-dimensional creature would be able to look at those two perpendicular rotations that I just described and understand that they lock you into one and only one rigid motion for the hypersphere.

从几何上讲，一个四维生物能够观察到我刚才描述两个垂直，并理解它们将你锁定在一个且仅有一个刚体运动中，对于超球体来说是这样。
