A non-scientist not knowing much algebra certainly doesn't imply he/she cannot understand the difference between pure and applied maths (to physics in this case).

"I think you underestimate some people's intelligence here."
I certainly OVERESTIMATED Sonhouse's comprehension of basic mathematics.
Indeed, I was shocked (as Blood on the Tracks apparently was) when Sonhouse failed
to comprehend the basic equation if A / B = C / D, then AD = BC.
It was obvious to me as a young child, shortly after beginning to learn arithmetic.
I was astonished that any supposed engineer could be so ignorant.
And I am astonished that Westerners here seem eager to excuse that ignorance in a Western engineer.
I expect that Chinese, Japanese, or Koreans would not excuse such ignorance in one of their engineers.
In general, many, if not most, of the supposedly 'well-educated' Westerners here show
obvious gaping ignorance, common blatant errors in reasoning, and near illiteracy in English.
Given their popular ideology of white racial superiority, of course, none of this matters much to them.
All that many, if not most,, white Westerners have to do is congratulate one another on
being white, which is taken as effortless proof of their superiority in about everything.
