Do you know about metric spaces? Would you like to be the subject of an experiment? Then Timothy Gowers needs you!
Gowers put a post on his weblog this morning containing five propositions to do with metric spaces, along with three write-ups of proofs of each proposition. He’s looking for feedback on how easy or hard to understand each write-up is, as well as how well-written they were.
If you’ve some time to spare, go and take part in the experiment over at Gowers’s weblog.
