Can math be useful for nature and engineering? Can you add apples and oranges? Can you add two apples? Can you describe any property of an apple using math?
Since you are a Ph.D in math, it will be good to know your views on the above questions.
(Also, I am not a Ph.D in math, but I tell you this: you can add apples and oranges, if you are interested in the set consisting of both these sets. Like, how much ascorbic acid would I get from eating 2 such-and-such apples and 3 such-and-such oranges.)
