Real life example needed

[AlanMiller]

OK, I'm stumped to find one!

There is exponential growth, like multiplying bacteria, there is exponential decay, like radioactivity, and there is logarithmic growth, like gaining aptitude through practice. But is there a real life example of logarithmic decay?

Logarithmic decay can only be a partial match for real-life phenomena, since it doesn't converge to 0 but diverges to minus infinity.
But apparently, the behavior of sprite lightning follows logarithmic decay to some extent. Search Google for sprite logarithmic decay.

Thanks Stuart. I did spot this one, but didn't read deep enough - thought it was just a misuse of the term, like people talking of any apparently rapid growth as (wow factor ->) "exponential".

Thanks Hans. That should keep me busy for the next few weeks trying to get a handle on it.
I hope the learning curve is more linear than logarithmic!
