1. What was John Napier famous for inventing? Logarithms
2. Who first argued that the world was not flat? (famously. Possibly Nog of Noggleland also had the same notion but alas no-one listened to him.) Your answer might be Christopher Columbus, but I would say Eratosthenes of Cyrene who calculated the circumference of the Earth in Egypt in c. 240BC and was only 1% in error.
4. How is a polygraph better known? Lie Detector
6. How many bones are in a human neck? 2, 7 or 31? 7
9. Which two elements make up the alloy brass? Copper and Zinc
3. Who invented the light bulb?
not Edison, who successfully commercialised it. Some Scot whose name I forget 
5. What was used to drive Charles Babbage`s calculating machine which is regarded as the world`s first computer? Electricity, Steam or Mice?
none of the above - I thought they had to wind it up by hand?
7. What nuclear process takes place in an atomic bomb?
fission
10. What quantity is measured in amperes?
current
Wiki page on Babbage suggests helio is quite right and that the first ones were mechanical and then he moved on to steam-powered engines. (My own PC, Doomed, is not much more advanced and does steam a bit at times as it slowly chunters its way through the few operations I ask of it 
)
2. Who first argued that the world was not flat?
Aristotle
A couple of Google hits seem to support this. Obviously a question with much-disputed answer. I am sure the chaircat knows as much and more than any old Google answer!
8. What is tocophobia the fear of?
Childbirth
Here's that lovely 'difference engine' put together by Babbage's son from parts left around his dad's lab. Suggesting that pcs then as now spent much of their time in bits on the bench waiting to be repaired. 
Must be the great great great great ....... grandparent of Hex!
