Thought I'd formally introduce myself...

First and foremost, I'm a farmer with a bunch of cows, the better part of them are pets.
I've always been very mechanically inclined, I love figuring out the why and how of something works, because if I can understand that, I am better prepared to fixing it when it doesn't work.
As my name would suggest, I have experience with Wankel rotaries.. I owned over a dozen rotary powered cars and loved them, but since I moved back to the farm, I don't do much with them anymore... I now have a old 12V Cummins diesel Dodge that I built a new engine for, completely restored, and put a variable vane turbo from a much newer truck on.. so it needed a lot of electronics to go with it... and LOTS of programming. So I have a little experience in C (Arduino controls the turbo over CAN bus), and for Windows my experience is mostly in VB.net. I live in a small town with a few mechanical shops... I'm the guy they call when they can't figure something out.

In a previous life, I was a packaging equipment technician.. In other words, I built machines that make boxes.. my specialty was "tray formers".. Some you may recognize are the trays that hold tomatoes, cucumbers and peppers at Costco, etc, but I built some that had 'cultured stone', or essentially bricks in a banana box.. I tested them, and an empty box filled with steel was 300 lbs, I put 2 of those on an empty box, and stood on top it.. very very strong! At this job I traveled all over North America and saw many placed I'd never otherwise see... At the shop I did assembly, drafting, machining, welding, and design, since the engineering department never got it quite right (Cardboard (technically called corrugate) is an imperfect material and not very predictable), I also did a lot of PLC programming and the machines were all controlled by 3ph inverter drives and pneumatics.

For my formal education, I was an ace student in high school, thought I wanted to become a veterinarian, but lost focus and my GPA tanked, I ended up with a good collection of 1st and 2nd year science courses, which I've forgotten a lot of (it was 20 years ago), but still remember the broad strokes and use them surprisingly often in theory, though I forget how to do the details.. Calculus is a good example, Maximizing or minimizing, limits, etc I can use in theory, though I forget the derivations for the different types of functions.

There's me in a nutshell!
Cheers!
 
Physics news on Phys.org
very detailed introduction, welcome on the forum
 
Thanks.. I was on a few other forums for a long time.. they've gotten boring... This place looks like a nice place to exercise my mind a little :)
 
Hello everyone, I'm Cosmo. I'm an 18 years old student majoring in physics. I found this forum cause I was searching on Google if it's common for physics student to feel like they're in the wrong major in the first semester cause it feels like too much for me to learn the materials even the ones that are considered as "basic math" or "basic physics", I've initial fascination with the universe's mysteries and it disconnect with the reality of intense, foundational mathematics courses required...
Hi there! This is Vmax, an old (relatively, but the profession can definitively accelerate aging) aerospace engineer now returning to physics in my 50s. I can definitively use some help in refreshing long forgotten topics and guidance in tackling new challenging subjects in modern physics. I'm looking forward to engaging in interesting, informative and stimulating conversations with you all. Have a great day!
