Physics Apps for iPhone: Any Advanced Options?

[Geezer]

I've always wanted to put some Physics apps on my iPhone, but the ones I keep coming across are way too low-level; they seem geared to high school kids who are first encountering the material...

Any recommendations for apps that are more advanced?, like upper-division or graduate student level?

DropBox? I store my .pdf archive of papers in DropBox (along with all the .bib files and annotations) and have access to them on whichever computer I use. If you have a particularly dry paper or two, it also doubles as a sleep-aid!

As for more advanced apps, I don't think you'll find a whole lot since the processing power on the iPhone is a whole lot less than what you'd have on a desktop, or even a netbook, and the input, while great for texting and e-mails, also isn't that great for extended input. Just my 2 cents worth.
