Erg

[cruzloco]

Is erg not a small unit, equal to a force of one dyne exerted for a distance of one centimeter? In the CGS base units, it is equal to one gram-square centimeter per second squared (g�cm2/s2). It is thus equal to 1 � 10-7 joules or 0.1 microjoule (�J) in SI units. It is approximately the amount of energy that a mosquito uses to take flight.

This is a question from an annual Quiz, kindly compiled by one person for a national body staffed by thousands of trained volunteers. The organisation exists to inform people of their legal rights and responsibilities, so the trained volunteers and their paid associates do have to develop some good research skills.
Each year there are 100 questions, set by the generous individual who (presumably) puts a lot of thought into making this a challenging-but-fun quiz, and who (indubitably) knows that the contestants are trained to research answers to tricky questions.
In recent years people�s research skills have developed to include the IT User's Friend, viz. the Boolean search on keywords over the Internet. Use of Mr Boole�s legacy is to be encouraged. And in certain circumstances, posting a direct question on a Quiz Answer Site - such as this one � gets as good a result as that which would be obtained by the boolean approach. And often much faster.
But the thing is, the Quiz Setter did make one request, which was:
�Naturally surfing the internet for answers is permitted but can I please ask you not to just post the questions on the net � that really is not in the spirit of the quiz.�
Shall we read that again? He asked: CAN I PLEASE ASK YOU NOT TO JUST POST THE QUESTIONS ON THE NET. Is this really so very difficult to understand?
There is no question of enforcing this polite request. Or indeed of policing any Quiz websites. If people really feel they have to post the questions on the net, then that is their affair. But in future years, would it not be considerate, at the very least, to ACKNOWLEDGE THE WORK that went into producing this quiz, and RESPECT the author�s request?
