Gradient
A difference in a quantity across space that creates directional flow. Concentration gradients (differences in substance amounts) drive diffusion, osmosis, and nerve signals. Temperature gradients drive heat flow.

"...p of market." (Importing the best talent requires active transport—the energy-intensive process cells use to pump molecules against the concentration gradient.) "Context, not control." (Give people information and trust them to make good decisions.) The culture deck served as a negative feedback loop."
"...(rotating its flagella in opposite directions, spinning randomly), and picks a new direction. This is chemotaxis: directed movement along a chemical gradient. The bacterium never "knows" where the glucose is. It just keeps comparing "now" to "just now" and adjusting."

Biological Context
Gradients store energy and information. Cells use concentration gradients to generate ATP and transmit nerve signals—sodium is 10x higher outside cells, potassium 30x higher inside, creating the electrical potential for neurons to fire. Developmental gradients position cells and determine their fate. Organisms orient themselves using environmental gradients (light, temperature, chemicals).
Business Application
Business gradients: differences in price, talent, information, or opportunity across markets. Gradients create flows—value moves down gradients. Arbitrage exploits gradients. Competitive advantage often comes from positioning on the right side of gradients.
