That's what happens when Engineering appropriates terminology from the Math department.....
Yes, quite: confusion arises; misunderstandings ensue; overly-confident haughty statements beginning with phrases like "I can assure you that..." are carelessly tossed about; and even when the confusion is exposed and cleared up in a sincere and polite way which should put the damn thing to rest, boring chauvinistic sentiments about My Field vs. Their Field are hid behind.
That is indeed what happens when some piece of terminology is used in two different fields of study. Which is too bad.
