I always wondered what would happen if you cite an original source of something we consider common sense now. What would nature say if you use conservation of momentum and cite Isaac Newton and the Principia Mathematica.

What if you quote something in latin. For most of science history this was completely normal.

Die Leuchtfeuer von Minas Tirith. Die Leuchtfeuer brennen. Gondor bittet um Hilfe.

I would say “High Temperatur Superconductor”. If they can be made cheaply, they solve our Energy Problems in almost every way. Turbines will become more effective, Transport of Energy cheap and lossless and storage crazy effective. They will also revolitionize meassurement of magnetic fields witch will have a huge impact on medicin and other fields.
