Getting up to speed in linear algebra and a reasonable familiarity with tensor calculus is a pretty big prerequisite step....
Also this book which I could definitely use. I'll take all the help I can get with relativity, thank you very much. 😂

Sharp cheddar and apple go well together, so I could certainly imagine a fruit pizza:
To clarify, I'm not saying blueberries inherently lack flavor. I'm saying that when you bake a blueberry on your pizza, it loses all flavor. I think it leaks into the cheese around it, along with the dye from the skin. The remaining berry is like a little wad of hot, unpleasantly textured slime.
Strawberries on pizza are delicious and I will die on this hill. Blueberries taste of nothing, BUT they dye the cheese around them purple, and this delights me, so I will always do it if given the opportunity.
