Are there any useful higher education apps for university/graduate level education? Organic Chemistry, Molecular Biology, Thermodynamics? "The Elements" is a decent start, but are there any Molecular Modeling applications that would largely eliminate the need for kits for example? The touch screen would lend itself quite well to creating three dimensional representations and eliminate the need for another thing university students need to drag around. I ask because a large portion of university students where I work seem to be embracing the iPad, and keep talking about the lack of actual educational software available aside from the worthless kiddie applications. I'd like to direct them somewhere but a majority of the applications seem to just be basic information that shows up on Wikipedia, only with more pictures. All the "2+2=?" apps are grouped with the university and graduate level applications which makes them even more difficult to find in the first place. Anyone know if there's a plan to dump all the kiddie garbage in a "K-12" section?
