Hope
I one day hope to discover a small historical innacuacy in a research paper, fall down a research rabbit-hole, reading random newspaper exerpts, visiting a libriary far away to dust off ancient un-digitalised research journals, to eventually discover a forgotten scientist who's very existence nobody knows about, and who's theories were ridiculed or overlooked at the time, but are either now central to the modern study of biology and/or have the potential to change the way we look at biology.
Alas.
