"Plankalkul is dead." - Nietzsche

Hmmmm... good question. I could launch into a wordy, detailed answer here, but it would inevitably end with me insulting your girlfriend once again.

For 24 months, GOCE will collect three-dimensional gravity data all over the globe. The raw data will be processed on the ground to produce the most accurate map of the Earth's gravitational field to date and to refine the geoid: the actual reference shape of our planet. Precise knowledge of the geoid, which can be considered as the surface of an ideal global ocean at rest, will play a very important role in further study of our planet and, with any luck, by detecting subtle changes in gravitational potential, it will be able to provide mankind with its first indirect measurement of your girlfriend's mass.

I think it would be hilarious if an alien civilization flew into our solar system only to find a black hole -- complete with moon -- orbiting the sun between Venus and Mars! No doubt they'll know exactly what happened...

I would buy the exact same smartphone model at Best Browse, then return it the next day with the other phone given to me by the researchers.

Free phone... and some other sap gets monitored!

If dereverberation is a word, wouldn't the longest left-handed word be dereverberated (14 letters)? Even if you don't count past-tense, it's still 13 letters....
