Did Anyone Else Notice that Van Jones...

Did anyone else notice that Van Jones used the same words, ‘inflection point,’ that Robert Gibbs used when asked about the oil spill?  Van Jones used it when he was talking about how this week would be marked in progressive history as an inflection point. 

If one imagines driving a vehicle along a winding road, inflection is the point at which the steering-wheel is momentarily “straight” when being turned from left to right or vice versa.  An inflection point is a statistical point in which a curve changes to another direction.

Funny, I’ve never heard that word before and now I’ve heard it twice in the period of a few days.  Coincidence?
