Welcome to my website containing technical notes, publications, and random musings. The website is a place where I document notes on topics of interest to me. For example, a few of my friends had a discussion about the periodic nature of the length of an day on earth as the planet moves through the seasons. Is it a simple sine wave, or something more complex. In the notes section of this website, you will find an unpublished paper describing the answer to this question. These are personal notes, not intended for publication. Recently, I was wondering how the Webb Space Telescope was able to orbit around a point without mass located on the axis between the earth and sun, and beyond the orbit of the earth about the sun. You will find my incomplete notes describing this problem. I wrote this up to share with my grandchildren who, at the time, were studying physics in high school.

During the COVID epidemic, I wanted to understand the concept of "flattening the infection curve." How, could various strategies be used to quell the epidemic? This led to a concept paper (unpublished) which you will find here. I did share this with our county health officer, and a number of other individuals. The intent of the paper was to look at the pandemic as a dynamic system and try to understand how different control strategies might affect the outcome.

In another section of this site you will find notes I have created as I learned the Python programming language. My first computer course in college was taught before the university even had its original computer--an IBM 1620. My first structured language was ALGOL, which I taught to students at Oakland University. Later, I learned C, and taught that language to freshman engineering students at Wayne State University. I have found Python and the many packages that enhance its foundation to be very useful, and easily executed on my laptop computer.

If I ever get to the stage of including my publications on this site, you will find that my interests are very broad. I have published papers on dynamic systems and control, optimal management of human population dynamics, statistical methods, robotics, manufacturing, engineering education, and even anthropology.
