It's amazing how back in the old days it came already downloaded and printed for you. Will you venture to name the reviewer?

PS The part about it sounding fishy was just a ruse.

I think it was Dick Olsher. John may remember better than I.

Vo ~ 10 x (Vi + .0001Vi^2 + .0002Vi^3 + .000025Vi^4 + O(5) )

If Vi gets large, then the higher order terms would be significant and the algebra would get messy. I'm too old to do messy algebra!
Ah but it is the small terms that are the game we are after. I don't mean anything personal by this, but this was supposed to be an easy math problem!

This thread is degenerating again. This Bybee thing has been beat to death but here we have the same people going at it again............guys I think it is time to move on. This childishness has to stop we know your opinions so stop sniping and agree to disagree.

It's all MY fault, everybody. Every underemployed individual can and will criticize me here. If I complain about it, it is my fault. If I bring up something new, it is my fault. If my associates tend to make audio products that can't be PROVEN with double blind tests to work differently than anything else, it is my responsibility for having them as colleagues. And so on, and so on! '-)

Default With all due respect

Mr.Curl did not start the thread so does not have ownership of it...........you could ignore him( a simple solution)..........but in his defense there seems a particular group that goes after him regardless, incessantly at that. If you disagree state you opinion and engage a discussion, if no conclusion is reached move on.

I am starting to feel that posting of cartoons (which I have been guilty of in times past) is more fruitful than this Bybee diatribe which attract trolls that suddenly appear out of the woodwork, invariably the same ones I might add.
