An Ultimate disc is a wing you can catch. 𐃏 It has no tail, no fuselage, and no static stability whatsoever — by the standards of a fixed-wing aircraft it should tumble within the first few metres. Instead it flies a hundred, because it carries its stabiliser as angular momentum. This treatise works through the mechanics in four movements: the disc as a rigid body, the aerodynamic forces on it, the gyroscopic dance that shapes every throw, and the resulting flight envelope. The canonical sources are Hummel’s flight simulations (Hummel, Sarah Ann, 2003), the Manchester wind-tunnel programme of Potts and Crowther (Potts, Jonathan R. and Crowther, William J., 2002), and Lorenz’s instrumented discs (Lorenz, Ralph D., 2005).1
Physics
Lesson 1: General Relativity
This and the next chapter are mutually exclusive. i.e. General Relativity and Quantum Mechanics cannot co-exist simultaneously.
Differential Geometry
Lesson 2: Quantum Mechanics
Differential Geometry or here.
Lesson 3: The Cosmos
Lesson 4: Quarks
Lesson 5: Loop Quantum Something
Lesson 6:
Heat, probability and black holes.
Things that obviously do tie together.
Lesson 7: Psychology; The Self.
Interestingly, the first Delphic Maxim at Apollo was meden agan, which is related to the importance of this notion of the self.
