Can someone either explain or point me to a visual example of this?
If you have an x-y axis and the line y=x and you rotate this line
along the y-axis, how do you get an upside-down cone? I can't picture
the result of that and it's been perplexing me for a very long time..
What does it mean "rotate this line along the y-axis?" I know
what rotate *around* an axis means, but I'm confused by rotate
*along* an axis.

... When resting on a flat surface, if it is given a push to make it rotate around its point of surface contact, it has the characteristic of moving smoothly in that direction of rotation but if given a push to rotate in the other direction, it will start to turn but then, with a rocking motion, come to a stop and begin rotating in the direction it somehow prefers. ...
