Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle scattering by kind, physics, measurement techniques and applications.

A physical process in which particles or waves, such as light, sound or particles, are deflected from a straight path by interactions with matter or fields; includes elastic and inelastic, Rayleigh, Mie and Compton scattering.

What it is for: Explaining phenomena and probing matter in science and engineering.

It can be explain why the sky is blue; compare scattering types; choose scattering techniques for analysis; interpret cross sections.

Distinguishing features

Deflection by interaction

Depends on wavelength and particle size

Quantified by cross sections

Basis of many analytic methods

What it looks like

Seen as haze, sky colour, glare or diffraction patterns.

How it is recognised

Rayleigh for small particles, Mie for larger

Elastic versus inelastic

Scattering of seeds or ashes is an everyday sense

  • How should techniques be linked?
  • How should the everyday sense be split off?
