Acoustics and radio engineer in the UK, aka @acoustics_in_uk on Twitter and @zark_off on Mastodon
And physicists are the biggest arrogant [censored]..
There's one in the UK university who thinks he invented a whole new physics field in a different subject area he's no experience in...
More than that, not even the field of physics he studies
engineers are in my experience absolutely the worst crackpots because they know just enough physics that they think they can make a contribution (or outsmart Einstein). They're the ones who come up with free limitless energy and suchlike.
