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

好了，现在我只需垂转机体，到绿灯熄灭。

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

龙卷风是转的垂气柱， 由雷暴形并延伸到地面。

It is perpendicular to that axis of rotation.

它垂个转轴。

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

它垂上升，转 90 度并进入您的髋骨。

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

转第一个圆， 使 1 位 q 所在的位置，然后将垂的圆转相同的量。

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900度翻转，他在U型池上方做了两圈半的垂转。

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.

就像转的陀螺与向下的重力相反以保持垂一样，转的橄榄球想要推动作用它的主要力量。

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，随着时间的推移，通过碰撞和崩解，星云失去了它垂转平面上的粒子高度变扁平状（大概是二维的圆盘）转，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.

它只是杠杆臂的乘积， 是一个矢量，必须垂转轴。

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的两个垂转，并理解它们将你锁定在一个且仅有一个刚体运动中，对超球体来说是这样。
