I created the MP3 below using the Universal Audio Hammond B3 plug-in.

Blog Entry © Saturday, September 28, 2024, by James Pate Williams, Jr. My Latest MP3
The following MP3, “Sextets on Fire” was created using Cake Walk’s SONAR Platinum Digital Audio Workstation with the Universal Audio Mini Moog Synthesizer emulator. I utilize three Nomad Factory audio effects:
- BT Analog Chorus with CP70 Piano Chorus Preset
- BT Valve Driver with CP-70 Piano Warmer Preset
- Blue Verb DRV-2080 with Small Bright Room Preset
The composition uses 42 six note chords repeated 4 times.

I created the following fast battleship Iowa class ballistics table using a single coefficient of form with the value 0.531. The ballistic coefficient is 19.86229.
For comparison use the actual October 1941 Iowa class ballistics tables:

I wrote a C# program to graph NASA’s Earth Atmospheric Model’s variation of air density with height in Imperial Units and the United States Navy’s air density altitude equation.
Earth Atmosphere Model – Imperial Units (nasa.gov)
The USN’s formula for density – altitude is found in “Exterior ballistics, 1935” by Lieutenant Commander Ernest Edward Herrmann who was an instructor at the United States Naval Academy.

My father, James Pate Williams, Sr. (Born November 8, 1912, and Died February 10, 1993) was forced to quit school at the age of thirteen in 1925 or 1926 and was initially a sweeper at the West-Point Textiles Company’s Dixie cotton mill on Greenville Street in LaGrange, Georgia. The reason he quit school was to support his birth family after they were abandoned by my Williams side grandfather. Sometime in the 1930s my father received a cost accountant degree from LaSalle Extension University based in Chicago, Illinois. He corresponded via mail with his professors to earn his degree. LaSalle Extension University was one of the first examples of a distance learning center. While on the job he used a Friden tabulating machine, a K&E drafting kit, and K&E slide rule. I probably got my love of mathematics and numbers from my birth parents. My father taught me how to use a compass, protractor, slide rule, and tabulating machine. He used paper spreadsheets and his Friden calculator to maintain household expenses and to document his and my mother’s income tax. My father was also in charge of the Civil Defense equipment stored at Dixie Mill. That Cold War era equipment included a Roentgen measuring device and Geiger counter. I learned how to use both Civil Defense devices while I was in high school.
