A note for beginners
Someone wrote me: "I do agree with all the concepts you’ve introduced to your post. They are very convincing and can definitely work. Nonetheless, the posts are too short for beginners. May you please prolong them a little from subsequent time? Thank you for the post."
My purpose here has been motivational. I could easily fill the blogs with mathematical detail. In college, my English teacher stressed that "a good article is like a woman's skirt; It should be long enough to cover the subject, but short enough to be interesting."
Use the hyperlinks given in the articles
There are many sites online that help with the mathematical details. KahnAcademy. com for example, or http://www.analyzemath.com/. Many more can be found by entering, "Math tutorials" into your favorite search engine. I do scatter some hyperlinks in my discussions to helpful material online.
