Ode to SnarXiv

So many things pass me by these days that I’m not usually surprised when I have no idea what people around me are talking about. I am however quite surprised that, until yesterday, never heard of the snarXiv. As its author explains:

The snarXiv is a ran­dom high-energy the­ory paper gen­er­a­tor incor­po­rat­ing all the lat­est trends, entropic rea­son­ing, and excit­ing mod­uli spaces. The arXiv is sim­i­lar, but occa­sion­ally less ran­dom.

The snarXiv uses “Context Free Grammar” together with a database of stock words and phrases to generate its content, which is actually just limited to titles and abstracts rather than entire papers. It’s just a matter of time, though. The results are variable, with some making no sense at all even by the standards of theoretical particle physics, but the best are almost good enough to pass off as real abstracts.

Here’s an example in the form of the abstract of a paper called (P,q) Brane Probe Predicted From Conformal Blocks:

Recently, work on new inflation has opened up a perturbative class of braneworld matrix models. We make contact with observables, moreover investigating trivial Beckenstein-Boltzmann equations. Next, using the behavior of a left-right reduction of models of WIMPs, we reformulate instanton liquids at the LHC. After discussing positrons, we check that worldsheet symmetric central charges are equivalent to electric-duality in gravity. Finally, we make contact with a special lagrangian brane, surprisingly obtaining models of inertial fluctuations.

Why not have a go at arXiv versus SnarXiv to see if you can spot the genuine article titles?

I’m tempted, with a nod in the light of the Sokal Affair, to suggest that a similar approach used in the social sciences, but the thing that really struck me is that someone should do a snarXiv for astronomy and astrophysics. Or is someone going to tell me it already exists?

Come to think of it, judging by some of the proposals I’ve read while serving on the Astronomy Grants Panel over the years, a similar generator may already exist for writing grant applications…
