SciFi: The unexpected problems with gravity
Artificial gravity in science fiction falls into three categories: Applied Phlebotinum works via madeup technobabble. Examples include the gravity plating in Star Trek. Spin gravity is where inertia wants you to keep going in a straight line, but centripetal force from your outer hull keeps pulling (or pushing) you towards your axis of rotation, creating…

Hᵤ(2, 2) = 4 for all u>0
A bit of recreational mathematics. I’d be (pleasantly) shocked if this is novel. 2+2 = 2×2 = 2² = 4 🤔 Hᵤ is the set of hyperoperations, e.g. H₁(a, b) = a + b H₂(a, b) = a × b Hu(a, b) = Hu1(a, Hu(a, b1)) when u≥3 & b≠0 ∴ Hu(2, 2) = Hu1(2,…
