So you've got yourself an iPad. We're sure you're probably playing Angry Birds HD or watching 30 Rock on Hulu, but it's time to put your iPad to good use. Here's a rundown of our favorite apps.

1. Papers. This must-have made the top of our list of iPhone apps for science nerds. Building on the success of its desktop and iPhone applications, mekentosj--yes it's pronounced like Macintosh--has built a fully optimized version for the iPad. Papers on the iPad is hands-down the best way to read, organize, and rate PDFs on the iPad. It provides quick access to a large collection of research papers and scholarly publications. Papers features a complete set of professional tools to help you organize, annotate, and expand your personal library of research. (Price: $14.99)

2. Evernote. For our money, (yes we know it's free), Evernote is the best note-taking application around. It's simple, robust, and more importantly syncs across all your devices. Evernote is increasingly becoming the go-to research and note-taking tool for students, teachers, and school administrators at all levels of education. Being able to take class notes on your iPad and then access, edit, and share them from anywhere is essential functionality. (Price: Free)

3. iStudiez Pro. There are a 1001 GTD--that's "get things done"--apps out there, but none of them are as specifically suited for student's needs as iStudiez Pro. iStudiez Pro separates its functions into five basic areas: Overview, Assignments, Planner, Instructors, and Holidays. The labels are self-explanatory. The combination of a fun and intuitive UI combined with the student-focused nature of the app is why iStudiez Pro made our list. (Price: $9.99)

4. Instapaper Pro. Even if your campus has Wi-Fi, that doesn't mean that you won't ever leave campus. Instapaper Pro makes it so that even if you don't have a constant connection, you can have constant access to articles and news posts that you enjoy. With Instapaper Pro, you can surf the web, and when you come across longer articles that interest you, save them to your iPad for later offline reading.(Price: $4.99)

5. WolframAlpha is a computational knowledge engine on the web. Looking to solve a math equation or find the current position of a comet? WolframAlpha's got your back. Need to compare the frequency of surnames in North America, quickly view the nutritional value of a meal, or analyze a gene and see its position on a chromosome? Yup, WolframAlpha does all that too. It's an amazing resource that can find out facts on all sorts of subjects and also does computations. And it's fun to simply pop from subject to subject in search of trivia and other compelling tidbits. (Price: $1.99)
