Sometimes an idea hits me and I feel compelled to write about it. Some of these articles are short and others are quite involved. They are all free.
Chaos: This is an article a former student of mine wrote about Chaos. Just the basic idea to start students on this fascinating topic.
Coronavirus: When COVID began in early 2020, it was called the coronavirus.I was fascinated by it from the start and when the numbers were relatively small (compared to what it became), I tracked them. This shows the very beginning of exponential growth.
Coronavirus 2: This continued the preceding article as COVID reached the U.S. and my naive thoughts that it would be contained. But again, the math behind this is fascinating.
Fairness: The concept of deciding what is fair from a math point of view interests me. This goes into a real-life problem in my condo association.
Flattening the Curve: In the early days of COVID in the US, the term that was on everyone's lips was "Flattening the Curve." This refers to flatten the exponential growth curve of the disease to a logistic one, which is studied in BC Calcuus. But all calc students and others can understand it.
Handshakes: A fascinating little study about men and women shaking hands using combinatorics.
Hurricane Dorian: When this major hurricane was flattening the Bahamas, its track took it right over South Florida and I was in its crosshairs. This was one of the biggest hurricanes ever and the damage it would have done is catastrophic. When its track shifted, there was still a chance that it could hit my area and with nothing to do but wait, I wrote an article showing the math behind its movement.
Reading Math: Years ago, I read math textbooks for the blind of dyslexic. It wasn't easy and this article talks about what it means to read mathematics to someone who cannot actually visualize it. I helped thousands of people I never met while doing so.
Slip-Sliding Away: Should you slide into first base or run through the bag? For you baseball people with calculus knowledge, this explains the mathematics of it. Included is a sample AP Problem.
What is Average? The term "average" is bandied about quite a bit but depending on the actual topic, it can mean amany different things. This is an in-depth study of average from a calculus versus a statistics point of view.
