Australian Air Force's Recruiting Puzzle Shown To Be Unsolvable

KernelMuncher writes "Australia's Royal Air Force has been left red-faced after a job ad asked applicants to solve a complex math problem that was revealed to be unsolvable. The service posted the puzzle in a bid to attract the country's best minds to its ranks. 'If you have what it takes to be an engineer in the Air Force call the number below,' it read, above a complicated formula which candidates had to crack. But there was a slight difficulty: The problem had typos and ended up not giving potential operatives the correct contact information."

    Your problem may be solved by means of a most ingenious proof I have, which the margin of your ad is too small to contain.

    Mathematicians don't bother with such low-level expressions. This is indeed a problem for engineers. A good engineer would know how to load the problem into Matlab (or whatever symbolic solver engineers use), and lean back while it computes the answer.

      A wise person knows what they do not know. I used to interview entry level programmers. I would ask harder SQL questions until they could not provide a good answer. Usually "what is a left outer join". The best non answer was "I am not sure, it is similar to this, and I know were to look it up". The worst answer (in a valley girl voice). "It is like a regular join, except like outer.".

    This. Most of what I'll -- for lack of a better term -- call applications engineering is done this way. You learn the math in high school and college so you understand the problems, not so you can solve them in your head. Even in research fields it's unusual to solve equations of this size by hand.
