Abstract: The philosophy of Tannaka duality tells us that we can understand geometric objects by studying their symmetric monoidal categories of vector bundles. Taking a liberal interpretation of this philosophy allows us to view any symmetric monoidal category as a(commutative) geometric object in its own right.

I will apply this philosophy to explain an analogy between Serre's formula for the category of modules on a projectivisation and a construction from homotopy theory not traditionally thought of as "geometric": that of symmetric spectra.
