Re: Math Word Problem

Guess Who,
I agree about the original poster being a troll and I was planning to post a caveat. He posts from a gmail account rather than a K12 email account. He has never posted on a teachers' newsgroup before. His other Internet posts (rishabhnasa@gmail.com) seem to be almost exclusively nerdy 18 yearold tech talk. He purports to have been a gifted 4th grade writer, yet few of his newsgroup messages would appear to be written by a gifted writer. Etc.
And, of course, the original post was total BS. There certainly is no group of 4th graders who can solve any word problem and there certainly isn't any teacher assigned to gifted 4th grade math & science students who isn't bright enough to quickly come up with hundreds of word problems which would totally baffle the little kiddies. Consider a very typical word problem in first order differential equations, which would be presented to first year math & science college students:
A container holds 100 gallons of 90/10 mixture of water/alcohol. A 50/50 solution of water/alcohol is added at the rate of 8 gallons per minute while the tank is simultaneously being drained at the rate of 10 gallons per minute. What is the alcohol content of the tank after 10 minutes, assuming continuous stirring of the tank contents during those 10 minutes?
This problem is well beyond the scope for any group of gifted 4th graders (or most adults) and yet there are word problems which are orders of magnitude more difficult.
Consider a problem from both philosophy and math: Humans are intrinsically rational creatures, yet many participate in lotteries, raffles and/or casino games in which basic game theory indicates that participation is "nonrational." 1) Analyze and explain this apparent irrational behavior. 2) Defend the premise that humans are rational while also defending traditional game theory axioms. 3) Discuss the fallacy that gaming rewards and losses have linear utility values. Support your thesis by analyzing the utility value of money, which, under casual observation, appears to be obviously linear. 4) Using nonlinear utility values for money in conjunction with intangible utility values, illustrate how participating in a casino game and attending a movie at a theater are possibly analogous  both are examples of "non zerosum games" in which all participants, including the operators, appear to "win."
This second question appears to be more of an essay assignment rather than a math or science word problem. But it really is a math oriented word problem and any reasonable answer will involve considerable math.
The original poster is an obvious troll. On the other hand, sometimes trolls stimulate some interesting discussions.

FYI: Since the 60's, game theory has explained very well why humans behave in many nonrational behaviors such as casino gambling. On the other hand, nothing but a "stupidity gene theory" can explain many other human behaviors.

The point of fact is that it was a troll, and he seems to have been imminently successful getting people to respond, hook, line and sinker. There is no way in H... that he has 4th graders understanding string theory. He doesn't understand it himself. Or, perhaps he's just setting up a satirical discussion on the concept of "gifted" students, which is also fair game.
