My undergraduate degree was in Mathematics (University of Dallas, 1971). My core interest is General Systems Theory. My career was mostly in computer programming, however, I also taught English, and high-school mathematics, in China for 9 years. I am currently semi-retired, drawing social security, and working on my various websites. As far as I am concerned, anything I do here is in the Public Domain.

comment Is there any significance to the logarithm of a sum?
I have up-voted your answer. (I’m not claiming to understand it - I’m just giving you the benefit of the doubt, namely, that your answer is indeed as astute as it seems.) Since you say in your profile that you are a non-native speaker interested in writing and speaking decent English, you might be interested in the learner-friendly front-end to the (free, online) Merriam-Webster dictionary that I am creating, at prof-vortaro-de-la-merk-angla.weebly.com
