I had to look up STEM to see what it is. Thanks for the information. Yes, you do admirably well in explaining things. I'm a welder by trade and most in my field are not even able to speak about the job with any proficiency much less trouble shoot things. Even a job supervisor at one point didn't understand why the welding equipment we had on shore was grounded improperly. I used the word "inadequate" which he failed to understand. He got pissed off at me, failed to take action so I did it myself. This sort of ignorance would drive me crazy on a job. It would have been nice to have a knowledgeable person who could explain it to them without curse words even if they deserved a good cussing out to drive the point home. I'd be more like the Gordon Ramsey of welding so that didn't get me far. On one job where the supervisor and all the foremen were instructing the entire shop to set their machines wrong I finally wrote to the manufacturer who informed me I was perfectly right. The very next day the argument started up again and I tried to explain the settings when the supervisor told me he's emailed the manufacturer and was told he was right. I told him, "No, you didn't. I emailed them and was told my settings are correct. I can go to the office and have the email printed out if you'd like to see it". Supervisor walked off in a huff. Foreman came to me a few minutes later and said, "Ok, I get it, your welds are good and that's not a problem but why are you setting up the machines this way and everyone else is setting them the other way". Me: "Because, you're all wrong and I'm right.". He walked off angry. Obviously I don't have your skills. LOL.
