[SystemSafety] Faults in maths proofs

[Olwen Morgan]

I misapprehended your meaning but I still agree with you. :-)

There's no shortage of piss-poor mathematics to be found among the 
lumpenengineeriat. Even the modest example I gave has subtleties that 
most engineers will fail at first to notice.

At least I can personally test soap powder in my own washing machine.
