Human inertia

The answer to this paradox is explained by dirt, leaks, and human inertia. A partial list of the causes of increased per-barrel energy use at reduced throughput is ... 

Body mass The mass of the unclothed human body in kg, which is a measure of its inertia, or resistance to any alteration in its motion. The mass of a given body is the same anywhere on the earth or in space.

Techniques like Random Stimulus initially might seem too disconnected in the way they lead to new ideas, but this disconnection from one s mental inertia is exactly what is needed. Humans naturally establish logic patterns as they process information over time, so creative thinking actually becomes unnatural. The only way to spark it is to move away from these patterns, and using Random Stimulus is one way to do that. 

It takes little thinking to understand why British industries should face such difficulties the situation is not specific to Britain. Like most human organizations, chemical industries find it difficult to overcome their own organizational inertia and when they must do so, they find it easier to copy someone else than to invent something new. However, copying always involves risks, if only because the borrower must assess whether the local situation is sufficiently analogous to that taken as model to insure a successful transfer. 

Fluid flow around a hair in an array depends on the relative importance of inertial and viscous forces, as represented by the Reynolds number (Re = ulp/p), where u is velocity, 1 is hair diameter, p is fluid density, and p is the dynamic viscosity of the fluid (viscosity is the resistance of the fluid to being sheared a fluid is sheared when neighboring layers of fluid move at different velocities). We humans are big (high 1), rapidly moving (large u) organisms who experience high Re turbulent flow dominated by inertia. In contrast, very small (low 1) structures such as aesthetascs operate at low Re, where fluid motion is smooth and laminar because viscous forces damp out disturbances to the flow. 

Structural measures include dimensions, masses (of objects, limb segments), moments of inertia, circumferences, contours, compliances, and any other aspects of the physical system. These maybe considered hierarchically as being pertinent to the total human (e.g., height, weight, etc.), specific body segments (e.g., forearm, thigh, etc.), or components of basic systems such as tendons, ligaments and muscles.
