one example;

in encryption, there are good math techniques that generate excellent 
codes, but the understanding of how to detect errors that occur to the 
encrypted part is usally varies from good to poor, to unknown. 
Calculation of the Probability of Undetected Error, PUE.  The encryption 
generation uses solid known math, but one cannot tell from that math if 
it can detect errors very well.  A few codes are fully known, most are 
unknown. The military has some codes run on special chips (by 
contractors) to find out by exaustive search this factor.

the encryption code generators are like a few good known threads in 
thousands of possabilities.  but the math is not there yet to show the 
other possabilities are good.




Statistics, - good book => the Black Swan where it was argued wallstreet 
was misusing the binomial distribution (book came out before the 2008 
crash).  (wall street was and still is)

in general, I think math applications has a hard time with 
multi-dimentional problems (or larger than 5 variables)


take a fastest route + minimize gasoline for Uber, over a 2 dimentional 
city, with streets and pickup times, and drop off time locations.
	for 1 car, 10 pickups(trips) during the day how does the computer 
determine the solution.
	for 271 cars, 4821 pickups,   etc...

this "bleeding edge" of math is what is being published in the 
professional journals today.  like going from the known, (math works 
fine) into the unknown (math starts to degenerate, solution sets vague...)
