I've just been informed by a reporter on my television that "... the (economic) slowdown is gathering pace". I'm not entirely sure that that makes sense. Any opinions, please?

Well, if you can speed up more slowly, can you not slow down faster?
The gathering pace metaphor is unfortunate, though. A horse can't slow down by gathering pace, so I guess that's what makes it sound odd. But we get the drift (and secretly we love this stuff, don't we?)

... (and secretly we love this stuff, don't we?) We do. I wonder why? |

It's amusing. I love a good mixed metaphor: hot potatoes coming over the horizon.

The rate of change of deceleration (acceleration). I have heard this used in my current employment. All the way through university I never heard it, or used it., my colleagues write as "mm/s/s/s", I hate this obviously, but can not get them to change it to its correct format. I think they call it "jerk" symbol j. |

Jerk>> How do you do the link thingy with the word "JERK" but with the link behind?  >>>update>> Thanks, Paul.

Oh, goody! I can start telling idiots that they're "third derivatives of position". |

Oh, goody! I can start telling idiots that they're "third derivatives of position". WOW! Have I actually provided the board with something they didn't know? I am truley amazed! 'bout time I gave something back  |

'bout time I gave something back You gave a little too much back, Vadim: it's spelt "truly". I wonder what they call a change in the rate of decrease of acceleration. |
