I read this essay by Alfred Jarry called, “How to Construct a Time Machine”, and I noticed something which I don’t think anyone else has thought of because I’ve never seen any criticism of the piece to suggest this. I seemed to suss out immediately that what he was describing was his bicycle. He did have that turn of mind. He was the kind of bloke who’d think it was a good joke to write this very informed sounding piece, full of really good physics (and it has got some proper physics in it), describing how to build a time machine, which is actually about how to build a bicycle, buried under this smoke-screen of physics that sounds authentic.
