Earth's temperature (time-scales)
Stability landscape of Earth
[Steffen et al. (12018 HE)]
Toy model (Landau-Langevin)
Multiple timescales in atom dynamics (my research)
Short times: vibrations in local atomic cage.
Long times: collective flow events (avalanches).
Emergence of multiple time-scales in condensed matter
Hot topic: multi length/time-scale modeling.
Multiple Time Scales in Life Sciences (diabetes research)
Short: Rapid up-and-down of insulin secretion rate.
Long: Essential secretion, at low rate.
[From P. Rorsman et al (12003 HE)]
Multiple Time Scales in Economics (Germany)
Short: Keynes' business cycles.
Long: Kondratiev-Schumpeter cycles.
Take-home message: Multiple time-scales is essential in many
scientific and social problems. Disregard of multiple time scales can
induce underestimation of long-time effects.
