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.

comment I want to learn math!
I’ve written a lot of instructional material for high school mathematics that I am in the process of up-loading to my Weebly-hosted website. I have put all of these materials into the Public Domain, and you can view or download them as you wish. Here is the link: public-domain-materials.weebly.com

comment Why do introductory real analysis courses teach bottom up?
I agree that the topological definition should come first. In support of this approach, I have written “A Short Intro to General Topology”, and put it into the Public Domain. Here is the link where you can view it or download it: public-domain-materials.weebly.com/…. Definition 290 is the relevant item.

comment Mathematics understood through poems?
I was going to add a poem of mine regarding the primes as an answer to this question. Since the question is closed, I posted it to my account in Ipernity. Here is the link: ipernity.com/blog/101198/379526
