This should not be news to anyone who has been married for any length of time.What does a cam shaft do?
What is a vertical flyback interval?
What role does expansion play in refrigeration?
What does an address bus do?
Timed delay of arrival is the basis of what common technological service?
What is the role of a CCD in a digital camera?
Name any space craft now in orbit around anything.
What does TCP/IP stand for?
What is the purpose of a torque wrench?
The questions measure, I think, the degree to which people understand the physical world in which they live. Now, I may be wrong (almost inconceivable, I know, it has to happen sometime, like an asteroid strike) but I will bet that anyone scoring perfectly on the foregoing will be male. In fact, anyone coming close will be male. Should this prove true, the conclusion must be that men and women inhabit utterly different head-spaces.
I'm also willing to bet that only men will use Wikipedia to look up the ones they don't know.
