A course at the University of Michigan ends with a live concert featuring students using iPhones as instruments. “Building a Mobile Phone Ensemble“ teaches students to code musical instruments for the iPhone, using the Apple-provided software-development kit. Georg Essl, assistant professor of computer science and music, says, "What’s interesting is we blend the whole process. We start from nothing. We teach the programming of iPhones for multimedia stuff, and then we teach students to build their own instruments.”
It's because it makes sense to use space telescopes to look at radiation that can't be observed with ground based telescopes, because the Earth's atmosphere absorbs all of it. Herschel with its three instruments (HIFI, PACS and SPIRE) operates in the submm and far infrared, a part of the spectrum inaccessible from ground, and will spend a lot of observing time e.g. to look at interstellar water, a molecule believed to play an important role for the cooling of star forming clouds.
