Or at least nearly all - it's lolmythesis.com, where people summarise their PhDs in one sentence (or, for those who can't count to one, a small number of sentences).
Some I liked:
"That Galaxy wasn’t the one we were looking for, and after careful examination we can say that it doesn’t have any other particularly interesting traits either."
- Dark Cosmology Center, University of Copenhagen.
"A well known chemical reaction works just like the literature said it would"
- Chemistry, University of Cambridge
"Using flash-cameras set up in the wild to count how many animals are in an area is a bad idea because bright flashes at night scare animals."
- Biology, Stanford
And, finally, one from France
"The people doesn’t understand."
- Political science, Sciences Po Bordeaux
