My boss’s son is a physicist and work in a research part of the government in defence.
He can’t tell anyone what he does. To the extent that he can’t put his experience on his cv as if he even said what type of techniques he knows people could work out what he does. Even his dad doesn’t know what he does.
Nothing is allowed in or out the office he works in without some insanely lengthy sign off process.
His marriage fell apart because of it which is very sad.
I’d love to know what he works on.
