Geeks

This is my life as the wife of a mathematician/neuroscientist and the daughter of a physicist...
My computer is from 2002, and at the time it was made, 20GB of memory was a lot. Of course, now your cell phone probably has more. Because of all the pictures I've been taking here, I've got less than 1 Gig left, so I decided it was time for an external hard drive. David went with me to help me pick one out.
Here is the e-mail David had me send to my dad to let him know about my new purchase. It's a puzzle (like those annoying questions on the SAT that start with "there's a train traveling west at 140mph..."):

We're in Frankfurt now. Our hotel has free WI-fi so I brought my computer. We went on a shopping spree here this afternoon and bought a new external hard drive for me!!! I'm set for life! Or, at least until I take about 640,000 pictures, and each picture will cost me .025 Euro-cents to store. A fantastic deal considering the 4GB USB-stick that we almost bought was 120 euros. The space/price ratio of the hard drive was 60 times better than the stick! so... what's the size of my hard drive, and what is the picture size setting on my camera?

Of course, my dad figured it out very quickly. And now David is quite proud of his work, and wonders if anyone else reading our blog wants to give it a shot. (if you just want the answer without all the math, just send me an e-mail)
