If it takes a "smartass" character to do so - so be it. The story is meant to inspire and bring across a message about the state of education. If it takes a “smartass” character to do so – so be it.

But I admire your superb analysis on the problem solution you even impress me on the way you dig an analogy of the student's premise to common situation in a classroom. I could somehow relate that to all my bookies professor during my college days who were just lazy to teach and just let students memorize the pages of the books.

A problem can have various solutions, which one to choose will depend on the constraints. A prerequisite to be able to pick out the best solution is that you have to think of multiple solutions first. Good one! I think this is a classic case study for software development.

We're looking for situations where we have a well-defined problem and have multiple solutions. Of course there are plenty of examples of this in Quantum Computing. Many are engineering type problems though: how do you build a qubit? Superconductors? Lasers? Ions in a lattice? Perhaps there are more ways to do it that we haven't yet conceived. Or, how do you measure the state of a qubit? But these aren't very well defined questions. I'm looking more for questions that are things like "prove this" or "calculate that". I vaguely remember one example from String Theory. Something about if you look at the string over time it forms an encompassing surface that can shield the universe from otherwise potentially disastrous events.

Science has never been so much fun! Geoff - the story would probably not have gotten as much popularity if students could not relate to the simpler approaches. I think quantum computation would be a fine example of <em>different thought</em> in modern Physics, especially as it relates to Computer Science. Students are taught to think linearly, in 1s and 0s. Though here's a new world that requires a completely different mindset - concurrent computation with states that are sometimes both 1 and 0! It could be mind boggling.

All the solutions to this problem could have been solved in the time of Newton (or even Galileo?). This makes it more accessible to the layman, but then you have to ask if there's really that much freedom of thought in modern physics. The answer is yes, there is still freedom of thought (I can't quantify how much, though), but it's still nice to see examples of it.
