I work in physics.
Throughout my graduate career, I heard about people who have been known to see work done in a talk and subsequently catch up to that work and then-some, and attempt to publish first. I ignored this lore assuming it wasn't really true.
Now I am presenting at a conference where there will be someone (actually a big-wig) who has a reputation for this sort of maneuver, and I don't have a pre-print yet to post online.
Any recommendations about how to mitigate the potential for this to happen (besides being ready sooner obviously, I'm working very hard on this work). Thanks.
