The first 5 were relatively simple (7 really, counting the first and last one here, for anyone with a modicum of science background with a dab of trivia knowledge/interest thrown in). The other 3, not so much...

What? You don't remember your Maxwell's Equations? Once upon a time, I studied these in college. Don't ask me to explain them now.
And as for PET scans, it looks like I was the only one to talk myself out of the right answer. I recognized "tomography" from CAT scans, but I never heard of using positrons for medical applications. There are isotopes that produce those naturally, without nuclear accelerators?

Yes, I studied them as well, once upon a time. A long ago once upon a time I might add! My guess on this one was based on a vague recollection at best.
Positrons have been used for some time in medical applications (tumor evaluation and scans for brain activity/function are the two that come immediately to mind) but it has only been the improved technology to allow for smaller particle accelerators that are a wee bit more affordable that PET scans are becoming a little more available and accessible since a facility can have ready access to the needed isotopes.
Because my father just had a PET scan I know that the isotope used is typically flourine mixed with glucose that is then injected into the patient.

My daughter is going to have a PET scan done on her brain soon, at my insistence. For that they need to have an cyclotron feeding directly into the exam room as they use oxygen-15 which has a half-life of just two minutes.
