the universe's promise that almost everything snaps back, until it doesn't.
means The property of a material or system to stretch, deform, or change under pressure and then return to its original shape or state once that pressure is removed.
from From the Greek 'elastikos,' meaning 'propulsive' or 'driving,' built on 'elaunein,' to drive or set in motion. Scientists of the 17th century borrowed it to name the springy quality of gases and solids — the thing that pushes back when you press on it. From physics it stretched (fittingly) into economics, biology, and finally everyday speech, where a deadline, a budget, or a person's patience can all be said to have it.
- hidden limit
- Stretch past the elastic limit, it stays deformed forever.
- economics steal
- Economists borrowed the word to measure how demand flexes.
- spider supremacy
- Spider silk outstretches steel before breaking.
- rubber paradox
- Heated rubber bands contract instead of expanding.
- resilin
- Insect protein rebounds with 97 percent efficiency.
