Pitch & Power, Altitude & Airspeed Question

[Alamanach]

This is truely the only correct explaination...

Epistemological silliness, though this takes us off on a wildly different topic. How we choose to order our knowledge and understanding of the world is largely arbitrary, and can be done in more ways than we could hope to imagine. As it happens, we've ordered our knowledge such that we end up with these concepts we call pitch, power, airspeed, and altitude. But all those concepts rest on ideas of length, mass, and time. And length, mass, and time are all ideas that people made up. We could have made up different ideas, and developed a science that was equally valid, but wholly different.
