I will absolutely take a look at that this weekend. And nope, physics hasn't changed a bit since 83 (although my physique has, but I was born in 83 and that's a different story).
No worries at all about insulting, I'm here to learn as much as possible. Just for those wondering, my background is basically what my dad has taught me, and research I do on my own. I've been interested in flight and aircraft design since I was a kid. I won an invite to NASA's Space Camp program in 6th grade for a Space Craft design program, but was unable to go due to money. Initial intentions in junior high and high school were to go through the UC Davis Aeronautical Engineering program, but I generally had problems focusing in school as it was usually too easy, and bored me. I usually aced tests, but didn't do homework or class work. Then I also started slacking off when I started getting paid to jump motocross bikes my senior year.
My dad's background is a masters in physics, and 30+ years designing power supplies for everyone from NASA and the military, to Honeywell home thermostats. I can't say (and don't know everything hes built), but I know the F-16 gyroscopes used power supplies he's designed. He also is a hobby engineer, building a robotic vacuum 20 years ago that relied on radar to map out the house. He's also been working on a voice recognition/simulation program. His goal is realistic sounding human voice, and is using FEA and Navier Stokes equations to do it instead of the common Fourier transform equations (which result in the metallic sounding "Steven Hawking" voice. I have a file that I'll ask him about sharing, that simulates air blowing through a tube, and it actually sounds real. He said it took 500 billion calculations per file, and there are 3 different tube length/diameters. His goal is to as accurately as possible model an average human lung set, voice box, throat, mouth, etc, to attempt to make the simulation indistinguishable from real human voice.
He actually recently left the company he was with for 30 years to start his own project, although I can't yet divulge what his new project is, it is something that most people would assume is straight out of a movie.
