Liberal Arts Become Mathematical

April 25, 2017

“Adding Math To Save Humanities” is the title of a sidebar article in the Wall Street Journal, April 25, 2017, about liberal arts colleges trying to add more mathematical contents to traditional liberal arts courses to better prepare their graduates for the work world.  Along with the Big Data revolution comes the need for employees in many diverse fields to be able to analyze data and to “rigorously and effectively” use data to answer questions.  “Emory University in Atlanta has created a degree that marries traditionally qualitative disciplines such as anthropology and English with math and statistics.”  This shift is in part to due students enrolling in liberal arts programs in smaller numbers.  Click below for the full article.

November 1, 2016

Movie directors use shapes as well as color, lighting and sound to create moods and tell stories.  Triangles, circles, and squares are loaded with feelings.  This short YouTube video (4 min.) describes some of the common uses of shapes to communicate with the audience beyond the conscious into the unconscious.

June 19, 2016

The Ten Commandments of Math

September 27, 2012

The Ten Commandments of Math

 1. You shall read your problems.

2. Whatever you do to one side of your equation, Do also to the other side.

3. You must use your “Common Sense”, or else you will have flagpoles 9,000 feet in height, and … even fathers younger than their sons.

4. You shall ignore the teachings of false prophets to do work in your head.

5. When you do not know something, you shall look it up, and if your search is not successful, Then you shall ask the all-knowing teacher.

6. You shall master each step before putting your heavy foot down on the next.

7. Your correct answer does not prove that you have worked your problem correctly. This argument will convince no one, least of all, your teacher.

8. You shall first see that you have copied your problem correctly before bearing false witness that the answer book lies.

9. You shall look back even to your youth and remember your arithmetic.

10. You shall learn, speak, write, and listen correctly in the language of mathematics, and surely A’s and B’s shall follow you even to graduation.
