You too, eh? I’m a lay scientist, but consider myself up to par with the PhD folks as far as keeping abreast of current physics, etc.
I understand.
When I looked for the author’s background I think I found here education listed as Psychology or a related field.
I have a business degree. But I have been a Ham Operator most of my life (& commercial radio license) and for most of the 14 years I lived in NM ran I with the techs and engineers from the labs.
I have also known a few “non-degreed” engineers who worked in the defence industry. Those “engineers” were head and shoulders above most of them. They started as tech’s and had a hands on background that the university only engineers did not. One of those techs worked for my father-in-law in the weapons industry. He was absolutely the brightest I ever met. He could smell the cause of problem by instinct. Amazing. His name was Dwyane Cauthorn, he went by DC (appropriate). He held several patents.
There was a time when many mechanical engineers had the grease under the fingernails experience before college. Many of those were tops too.
