Here's the second half of the quiz. This will probably go up on Sploofus sometime this weekend, BTW, if you want to look really smart.

D. Inertimeter

7. Which of these types of earthquake-generated waves does not travel primarily along the surface of the Earth?

A. Rayleigh waves
B. Love waves
C. Surface waves
D. Shear waves

8. Who is given credit for “uniting” the forces of electricity and magnetism, by writing 4 equations that can describe all electromagnetic phenomena?

A. James Clerk Maxwell
B. Benjamin Franklin
C. Isaac Newton
D. Michael Faraday

9. The Balmer series (along with the Lyman, Brackett, Paschen, and Pfund series) are important achievements in spectrometry. Which element was being analyzed?

A. Carbon
B. Oxygen
C. Hydrogen
D. Gold

10. In medical imaging, what does the acronym PET (as in PET scan) stand for?

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. :P

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.
